Earth Reference

Compact writer-facing reference for the modern Earth sequel. It combines the useful functions previously served by world, map, and ecology files without attempting to catalogue real Earth.

Add a place, institution, technology, animal, plant, or environmental detail only when it has appeared in prose, is likely to recur, constrains continuity, or carries clear narrative purpose. Verify changeable real-world detail when a chapter depends on it; do not convert incidental research into canon.

Earth Continuity

Ch.433-440 Earth Continuity Additions

Location Register

Place Status and continuity use
Sendai, Japan Current city and principal Earth setting. Thomas has prior experience of Japan but not automatic knowledge of Sendai, its local systems, or every change since his original life. Use real geography accurately when relevant, but establish only locations that matter on page.
Hospital / emergency department Thomas and Isha awaken here after the recorded road accident and a coma lasting several days. Ch.278 later returns Thomas by ambulance after more than five minutes without meaningful stable waking and fluctuating recognition. ECG, blood tests, neurological checks and non-contrast head CT find no acute cause; he is discharged after recovery with ordinary follow-up. The hospital's name, precise district, room number and recurring staff remain unestablished.
Residential district east of central Sendai Broad location of their home. The neighbourhood mixes apartment buildings, tiled houses, utility poles, small gardens, compact parking, local shops, and practical public transport. Do not assign an exact district or address until the home station, river, university, and later GIS layout are chosen together.
Thomas and Isha's current flat (202) Large rented Japanese-2F / GIS-level-1 corner home chosen after the Akiyama family moved out. It has a genkan and short hall, separate WC and wash/bath area, three bedrooms, an LDK whose kitchen and dining occupy the inner elbow, a quieter main bedroom, deep bedding storage, two exterior aspects and a long balcony that turns around the outer wall. Thomas uses one smaller room as an office; the other remains flexible for guests, storage, drying and camping equipment, with the floor and fully opening door protected as deliberate constraints. The refrigerator, sink and counter can operate without the old two-person conflict. Restoration before handover included damaged wall covering, partial kitchen-floor repair and replacement of the old air conditioner. Unit number 202 and its relative position are canon; surveyed dimensions, exact orientation and final furniture layout remain open.
Former flat (304) Modest Japanese-3F / GIS-level-2 flat supplied with their recorded identities and occupied through Ch.237. Its compact kitchen, LDK, double bedroom and overloaded second room shaped early Earth domestic life. Thomas and Isha vacate, clean, document and return it after the Ch.238 same-building move; the tenancy has ended and it is no longer theirs. Preserve it as historical setting and an unassigned/vacant unit until future prose gives it another resident.
Nearby narrow river and cherry-lined path Two streets from the flat. A regular walking route follows the engineered river for nearly a kilometre beneath cherry trees, with older stones, retaining walls, moss, weeds, swallows, bridges, benches, cyclists, children, and distant wooded hills. It is Isha's first recurring proof that Earth remains alive beneath its infrastructure. Ch.241 adds a small riverside recreation ground with a fenced ball court, exercise bars, benches and faded community markings at ten-metre intervals to an uncertified 100 m line; Isha's informal 12.94-second standing-start run there is not directly comparable with the municipal-track result. Exact river and recreation-ground identities remain unestablished.
Nearby convenience store Walking-distance shop used during Isha's first shopping lessons. It establishes automatic doors, chilled shelves, hot cabinets, rapid clerk etiquette, cash, cards, and self-checkout. Chain and exact location remain unestablished; it may recur for small purchases, payments, deliveries, and language practice.
Local food shop / supermarket By the third week Isha can shop here alone from a kana-marked list, buying vegetables, rice, fish, and the wrong kind of flour. It may or may not be the convenience store. Treat it as the main regular grocery location unless later prose distinguishes several shops.
Neighbourhood hardware shop Found by Isha after a loose cupboard hinge evokes Kelda. Thomas and Isha buy suitable fittings and learn practical tool vocabulary. Useful recurring location for repairs, household competence, and Kelda-associated memories. Exact premises remain unestablished.
Sendai Station Main rail hub used for travel beyond their neighbourhood and the natural transfer point for the first countryside trip. In Ch.226 two intoxicated men harass and grab Isha in a public station area; she moves toward staff/cameras, uses controlled redirection without striking and makes a formal complaint. Footage, two civilian witnesses and police photographs support her account. By Ch.236 the man who grabbed her admits it after seeing the footage and receives a fine through summary procedure; the second man is not separately charged, and both are instructed not to contact her. The exact home-to-station route remains open until their local station or bus connection is fixed.
Oku-Nikkawa Station and lower ravine trail Canon destination of Thomas and Isha's first train trip beyond denser Sendai. Reached from Sendai on the JR Senzan Line. They leave at the quiet mountain station and follow a maintained lower route through cedar, pine, and mixed deciduous woodland, crossing a stream by a small bridge before returning the same day. Exact trail branch remains flexible; recheck real access conditions when revisiting it in prose.
University and campus Their records show them as recent graduates of the same university. The institution anchors Matsuda, their former seminar adviser, archery and climbing contacts, qualifications, and possible work or social return. Name, departments, degrees, and full campus layout remain unestablished.
Library-side three-cherry-tree bench Campus micro-location shown in an inherited graduation-era photograph. Thomas and Isha find the same bench and take their first genuine Earth photograph there. It is a strong recurring site for distinguishing supplied continuity from lived memory.
University international-support office Thomas's workplace from Ch.221 and initial posting after becoming regular administrative staff on 1 June 2027. Ch.350-354 add the late-summer four-date arrival pilot: entry into Japan, first university contact, enrolment completion and local address remain separately owned milestones, with a shared exception view rather than one international-support master date. Thomas coordinates but does not enter another office's date merely because it emails him. The pilot functions while he is absent at regular-staff induction. Mori, Endo and Sugiyama remain established staff; the university name and exact building remain unassigned.
Campus gym / athletics building University facility used by Thomas during weekday lunch periods from before Ch.231. It is near his office building and set behind a larger athletics hall; Thomas and Isha reach the campus area from home in less than roughly twenty minutes by the route used in Ch.231. Contains maintained cardio machines, resistance machines, dumbbells, benches, squat racks with safeties, barbell platforms, trap bars, cable stations, pull-up frame and a marked 30 m carry strip. Staff recognise Thomas as a regular. Ch.244 establishes card-controlled reduced-year-end access from 05:00 before the staffed desk begins at 07:00; the weight area can be empty during that interval, but this is not a standing claim about all future opening hours. It supports Thomas's technically careful novice routine and Isha's one private progressive strength assessment; exact campus and facility name remain unassigned.
Follow-up clinic / physiotherapy practice Recurring medical setting during early recovery. Staff document Isha's exceptional but human balance, grip, reactions and endurance. The bicycle-and-child incident occurs outside after an appointment. After the Ch.278 event a clinic reviews the hospital record, finds a normal examination, permits ordinary work if symptoms do not recur and arranges non-urgent neurology review. Name and exact location remain unestablished.
Endocrinology clinic / laboratory Late-November through February setting for Isha's Graves-like diagnosis, blood tests, ultrasound, dose changes and remission monitoring. It records mild diffuse enlargement, positive TRAb and elevated thyroid hormones, then an unusually rapid but medically plausible normalisation. By Ch.323-325 the gland has normal size/vascularity, antibodies are undetectable and thiamazole is stopped; a later off-medication test remains normal. No staff member suspects the System. Name, district and recurring clinician name remain unestablished.
Kyūdō dōjō Traditional Japanese archery setting introduced in Ch.305 under Fujisaki Tomoko. It includes makiwara work, borrowed yumi, formal entry and group shooting at twenty-eight metres. Isha's prior archery accelerates safe handling and accuracy, but the eight stages, timing and group line remain distinct study. Exact club, district and governing association remain unassigned.
Book market / small-press venues Thomas and Kanno's earlier book-market day strengthens their direct friendship. On 24 July 2027, Kanno takes twelve copies of Until Replaced to a civic-hall small-press event with rows of half/full tables, zines, photo books and handmade publications; Isha briefly translates for an English buyer who later proves to be Ian. The exact book-market and civic-hall venues may be distinct and remain unassigned.
Small Works Weekend / municipal exhibition rooms Completed Saturday, 25 March 2028. Six regional makers share tables and short wall sections in municipal exhibition rooms west of Sendai Station. Kanno shows Until Replaced plus three existing photographs from that work, joins the optional maker conversation, sells several copies and leaves the unfinished wall/trace series unresolved. Female coordinator Okabe manages setup/break cover and is distinct from alumnus Okabe Jun. Exact venue/business identity remains unassigned.
Small paper / bookbinding shop west of central Sendai Ch.353 destination for Isha's deliberately unnecessary paper errand while developing her second hanging. Sells decorative papers individually, including imported/Japanese sheets and bookbinding materials. Exact business and district remain unassigned.
Unnamed central/western Sendai hotel used by Ian Medium-sized ordinary hotel encountered by Isha on 12 August 2027. Ian says he is staying there while visiting Japan for work. The hotel is demonstrably operating on 12 August, then closes on 21 August-10 September 2027 for scheduled facility renovation/building-services/lobby/equipment work, with reopening planned 11 September. Isha feels no unusual “weight” when she deliberately walks past the closed building without Ian present. The hotel is not a supernatural site and Ian's later location is not investigated.
Ian's external-world house, study and garden Ian states that his real-world home is in Otley, West Yorkshire, England, in his own external reality rather than the protagonists' Earth. Kelda, Lethira and Aelira inspect the study through a Ch.371 threshold without crossing. In Ch.423 Lethira receives three actual photographic prints made by Ian. The first, explicitly five by seven inches, shows a lawn-and-tree garden bounded by tall hedges and a small black shed; Ian says a warehouse is hidden behind the tall hedge, although it is not visible. The second shows broad stone walls beneath a single-sloping roof, with its higher side facing the lawn, plus large windows and glazed doors; Lethira infers that the house may have been designed for the view or the sun. Ian identifies the second upper window from the right as his study. The third is a near-current view from that study. Exact address, plan and external-world date remain unestablished. The photograph described as “now” is Ian-local only and gives no conversion to Earth or fantasy-side time.
Ian's neutral café construct Non-Earth meeting place first entered by Thomas/Isha through the flexible-room door on 18 December 2027 and later by Kanno alone on 8 January 2028. It resembles an ordinary quiet English café but has no established geographic world/location. Door access, concurrent Earth time and return destination are negotiated per meeting. It is Ian/external-mechanism infrastructure, not Homegate, the Hero System or a room physically added to 202.
Berlin — Kanno/Ian brief visit Ch.385 takes Kanno from the neutral café to real Berlin in the same Earth as Sendai for roughly thirty minutes, with Ian physically accompanying her after explicit consent. Ordinary people, weather, traffic and imperfect photographic conditions remain. Kanno photographs traces of the former Wall rather than a staged tourist view. The trip does not establish normal immigration/transport capability for the cast or standing permission for Ian to enter Earth.
Venus — Venera 14 site Ch.394 takes Kanno through an Ian-made doorway from her own flat to the actual Venera 14 landing site after she explicitly sets conditions. The lander/site are not moved, repaired, relit or beautified; Kanno uses her own unchanged camera, perceives the real Venus environment as far as Ian can make safe, remains physically unharmed and leaves no lasting footprints/fingerprints/fibres/biology. She makes twenty-seven frames; Ian makes three consented photographs of her with the same camera. The doorway later returns Kanno directly to 202 while Ian remains on the Venus side. This is external-mechanism travel, not Earth transport, Homegate or Hero-System passage.
Mars — Olympus Mons first survey On 27 February 2028, Thomas, Isha and Kanno travel with Ian to the real Olympus Mons after Isha accepts a first-look survey under a bounded safety model. Real Mars gravity/terrain and ordinary fatigue, soreness, blisters and non-catastrophic consequences remain meaningful while catastrophic injury/death is prevented; ordinary discomfort is not automatically healed. Isha learns self-directed flight, surveys from the air and carries Thomas during part of the flight. Kanno makes actual camera files and permits Ian to make photographs with her camera; those Ian-made frames are marked separately in her archive. No climbing route is selected and no climb occurs. Isha wants a longer second survey before deciding what, if anything, to climb. This visit is separate from the 16 April canyon-rim ticket trip.
Unnamed Sendai mineralogical/material-description firm Ch.397-415 route for Isha's large gold-bearing quartz specimen after Matsuda's bounded referral help. Staff first review photographs, then geologist Morishita conducts a roughly ninety-minute non-destructive examination on 29 March 2028 using visual inspection, magnification and controlled photography. Optional XRF of darker exposed material is declined because it is unlikely to change the useful answer. The written report arrives 13 April and supports natural native gold in quartz with iron-bearing sulphide, repeated hydrothermal fracture filling/mineral deposition and possible later deformation/remobilisation; no locality/age/mine can be inferred. No further work is planned absent a new question. Exact firm name/address remain unestablished.
Mars — canyon-rim ticket visit On 16 April 2028, Thomas and Isha use Ian's Mars ticket together. They experience real Martian terrain, reduced gravity and a vast canyon/rim landscape, take ordinary phone photographs and return to 202. Thomas considers Valles Marineris as a possibility, but the exact site is not canonically identified. This is explicitly not the future Olympus Mons climb. The physical ticket remains afterward; reuse is untested.
Mercury — Kanno ticket visit On 16 April 2028, Kanno uses her separate Mercury ticket alone with one camera body and two lenses. She experiences hard light, black sky, reduced gravity and an unidentified cratered site, adapts her exposure/walking rather than receiving photographic correction, and returns to 202 with 41 new frames. Exact coordinates/site identity remain unestablished. The ticket remains physically present afterward; reuse is untested.
Small neutral meeting room / garden construct Distinct from Ian's English café construct, the larger reunion café/garden and the later Golden Acre construct. Used for Kanno's 2 April meeting with Lethira, 19 April first meeting with Aelira and 27 April Aelira portrait session under fresh occasion-specific access and direct return. The camera session has separately negotiated recording permissions; no prior route or consent remains standing.
Golden Acre Park neutral construct Completed one-time setting for the 24 April Isha/Kanno/Aelira/Lethira afternoon. Ian bases it on Golden Acre Park near his external home: mature trees, paths, lake, smaller water arm, benches, lawns and picnic provision under deliberately perfect weather. No ordinary park users, dogs or birds appear. It belongs to neither inhabited world, closes after the last person leaves and grants no later access.
Wedding restaurant / private courtyard room Unnamed small restaurant in a low modern building a little west of central Sendai. A private room faces a modest courtyard with wet/dry stone, shrubs and two young maples; the room itself works as the complete rain plan. Level entrance/side taxi access, same-level accessible toilet, close seating and a short room solve Saitō's access and the couple's no-long-aisle requirement. Thomas and Isha choose it after two visits, book Saturday 30 October 2027, hold their own short ceremony there and eat at one long table with seven guests. The manager supplies sequence/logistics rather than an officiating religion or legal function. Nagai photographs the wedding. Exact business name/street remain unassigned.
Sendai ward-office family-register counter Exact ward and office name remain unassigned. Thomas and Isha use advance document review after their Tokyo marital-status appointments, then file the marriage notification during staffed hours on 15 October 2027. Kanno and Matsuda are the two adult witnesses. The notification is accepted that day and they request an ordinary Certificate of Acceptance/acceptance record. Keep future references at the level established in prose unless a specific ward is deliberately canonised.
British Embassy, Tokyo — marital-status appointments Thomas and Isha travel to Tokyo on 13 October 2027 for separate appointments tied to the British freedom-to-marry documentation required for their Sendai filing. The trip is procedural and ordinary; Matsuda meets them for lunch and signs the second witness box on the Japanese notification. Do not invent a special diplomatic relationship or recurring embassy contact.
Kameido and Shin-Kiba present-day route During Thomas's twenty-fourth-birthday Tokyo weekend, he and Isha walk present-day streets associated broadly with Daniel Mercer's life. They do not locate his former flat, identify a verified death site or search his name. The route remains a restrained first-life side story inside a current visit to Matsuda.
Road-accident crossing Official site of the compact car's rain-related skid onto the pavement. Exact location, driver, responsibility, witnesses, and investigative history remain unestablished and should not be invented unless the story returns to them.
Modern target-archery ranges Kuroda first helps Isha return to modern archery at a quiet club range using a light bow. Ch.321/326 add a municipal indoor range inside a larger sports hall, supervised by Nakahara, where Thomas begins on sixteen- and eighteen-pound recurves at ten metres; by July he is shooting ordinary beginner ends at eighteen metres. The venues may be distinct; exact names and governing bodies remain unassigned.
Municipal sports centre / judo dojo Historical adult-beginner judo venue for Thomas and Isha. Nakamura led fundamentals; Isha also attended supervised intermediate work. Thomas formally leaves in Ch.298 after recognising that the routine mattered more than the activity, and Isha's later calendar no longer includes judo. Either may return only under ordinary beginner/specialist terms. Exact centre and district remain unnamed.
Miyagino-area mixed martial arts gym Second-floor gym above a bicycle-parts shop, introduced in Ch.260 after Abe refers Isha to Shibata Kenji. It has a matted room, heavy bags, padded wall, short chain-link section, reception/equipment area and beginner/intermediate sessions. Isha attends mixed and grappling work; Thomas does not train there. Morita Ayaka's candid candidate review occurs in the small office. The later novice bout is held at a separate modest local sports hall under ordinary officials, medical checks and corner procedure. After remission Isha returns to controlled pads, clinch and positional ground work but not hard sparring or immediate bout preparation. Exact gym, event-hall and affiliation names remain unestablished.
Climbing centre Isha's workplace after a successful interview and supervised training. She is an indefinite short-hours regular employee, guaranteed three shifts / twenty-four prescribed hours weekly, with instruction/safety responsibility and First Aid Provider certification. She completes Coach 1 on 22-23 April 2028. Ch.436 gives her a first forty-five-minute beginner block with Yoshida nearby for floor coverage; Ch.440 shows ordinary follow-up work with Horie, Kameda, Nishimura and Sakai. The qualification broadens assignable beginner coaching inside existing hours without creating management, medicine, a fourth day or automatic progression. Exact brand, district and route remain unassigned.
Municipal athletics track Community track used with Hasegawa for electronically timed adult sessions. Isha records 12.72 seconds in Ch.223 and, after medical remission and improved start mechanics, 12.38 seconds with legal wind in Ch.324. One maximal run answers the question; the result does not make her a committed sprinter. Exact facility remains unnamed.
Nobiru Station and former-station memorial Current station stands on higher ground after post-disaster railway relocation. Thomas and Isha visit the preserved former platform and memorial museum, where maps, testimony, images and damaged objects record the 2011 earthquake/tsunami and rebuilding without implying restoration of the unsafe route.
Miyato Island / Oku-Matsushima Setting of their first one-night leisure trip after beginning work and, on 6-7 November 2027, their one-night honeymoon return after the wedding. An inhabited coastal landscape of settlements, fishing equipment, fields, wooded slopes, sheltered bays and open-Pacific views rather than a resort-only backdrop. The November return is intentionally not a reenactment: colder weather, no swim, shorter daylight, harvest-bare fields and a deliberately shorter walking route.
Aomina Visitor Center and Oku-Matsushima trail Trailhead and practical visitor anchor for the roughly 10 km route used in Ch.222. Staff provide water and route advice; the walk links temple, museum, Satohama historical ground, inner bay, Tsukihama, forest and Otakamori.
Satohama Jōmon museum / shell mound Museum and historical landscape showing long habitation through pottery, bone tools, fishing equipment, reconstructed dwellings and accumulated shell-mound layers. It prompts reflection on ordinary life becoming evidence without being created for remembrance.
Hatsutsuura and reclaimed/coastal fields Sheltered inner-water section of the Miyato route, with boats, heron, managed banks, fields and drainage. Reinforces land as maintained agreement with water rather than untouched possession.
Tsukihama Beach Sheltered beach near the minshuku. Thomas and Isha first arrive at sunset in Ch.221, then return during supervised hours in Ch.222 for their first Earth sea swim together. It is pleasure and trust, not a beach-resort or danger spectacle.
Otakamori 105.8 m viewpoint overlooking Matsushima Bay, wooded islands, settlements and the Pacific. A stranger takes the couple's first genuine shared summit photograph on the initial summer trip. On 7 November 2027 they return in sharper autumn light and ask another stranger for new photographs, including one close echo of the old pose and one with Isha kissing Thomas's cheek. The July and November images sit beside each other in the shared album without either replacing the other.
Miyato minshuku Unnamed practical two-storey lodging near Tsukihama, run in part by Sakamoto. Tatami room, reservable bathing, local seafood meals, trail advice and luggage transfer support the first one-night trip and the 6-7 November 2027 honeymoon return. Thomas quietly requests the same room if available and Sakamoto gives them that familiar room; breakfast is moved to 08:00, she supplies practical autumn-route warnings, luggage help and small congratulations sweets/dish. Do not assign a real business name unless deliberately researched and canonised.
Unnamed Sendai-area museum / bow display Ch.277 setting for a bounded historical-bow exhibit. Isha understands recent-to-her principles of wood, draw, balance and construction but does not possess specialist knowledge of ancient Earth bows. The exact museum and collection remain unassigned.
Unnamed Sendai-area aquarium Ch.280 evening setting with local fish, moray eel, giant isopod, sea angel, jellyfish, octopus and a large central tank. The late opening gives Thomas and Isha a low-exertion public outing after hospital recovery. Isha buys a small red octopus key ring; exact aquarium name remains unassigned unless later prose fixes it.
Sendai Station shopping arcade / purikura booths Kanno takes Thomas and Isha to a purikura booth after the aquarium/hospital week. Filters enlarge eyes, narrow faces and add fantasy ears/horns; a later unfiltered photograph at 202 supersedes the booth image as the clearest three-person record without erasing the comedy. Exact floor and booth brand remain unestablished.
Unnamed tattoo studio Private studio where Nagase consults and tattoos Isha's inner left upper arm in Ch.284. It has a private working room, padded arm support, mirror, sterile single-use equipment and ordinary aftercare procedure. Exact business name and district remain unestablished.
Central Sendai Tanabata arcades Ch.289 final-afternoon setting in early August: covered shopping arcades filled with low paper streamers, food stalls, seven traditional ornament displays and a public tanzaku wish station. Isha's height repeatedly meets the hanging paper. She wishes to learn to make something beautiful no one needs; Kanno wishes for one client-free Saturday each month; Thomas wishes to stop reviewing every judo throw before standing.
Sendai Airport / Incheon International Airport / Da Nang International Airport Flight chain used for the short Ch.267-270 Vietnam holiday. Return travel is Da Nang to Incheon to Sendai. Ordinary check-in, border, weather, gate-change and customs procedure apply; no police restriction is placed on the couple.
Unnamed primary hotel — Da Nang, near My Khe Beach Furnished base for the Vietnam holiday. Distinguish it from incidental bars or transit spaces. It supports ordinary rest, clothing repair, packing and recovery after the street incident; exact business name remains unassigned.
Marble Mountains, Da Nang Hot stone, stairs, cave/temple spaces and climbing/walking during the holiday. When no one is close, Thomas uses Lv.4 Cleanse to remove sweat and cool Isha's overheated back/spine by a modest amount, briefly disrupting her composure. Use ordinary heat, tourist access and footing constraints.
Hoi An Day/evening excursion for food, streets and ceramics. Thomas and Isha buy small ceramic cups, including the later green cup whose rocking is an ordinary balance/footing issue rather than magic. Keep the trip grounded in ordinary visitor movement rather than exoticised danger.
Unnamed quiet bar and camera-poor lane — Da Nang, outside the main tourist flow Final-night confrontation setting. Two men harass the couple in the bar, one attempts to punch Thomas and both follow them into a lane without useful cameras. Isha disables them with controlled force; police arrive afterward. The lane is not a recurring criminal location and creates no organised-crime plot.
Hobart / Freycinet Peninsula / Wineglass Bay, Tasmania Ch.247-250 eight-day international trip using supplied British/Icelandic identity documents, flights through Tokyo and Australia, a supported multi-day Freycinet walk, Coles Bay recovery, Bonorong wildlife visit and Tasmanian Museum and Art Gallery. Thomas and Isha return to Sendai afterward; this is a completed travel setting, not a new base. Preserve ordinary border, flight, weather, injury and pack-weight constraints if referenced.
Matsuda's Tokyo company flat Furnished temporary home for his written eighteen-month transfer beginning after Golden Week. It is in Shinagawa, roughly fifteen minutes from his office under optimistic interchange assumptions, with one induction ring, narrow counter, small sofa, folding chair and balcony rules. The plant, old mug, good knife and selected photographs travel with him. Exact building and office remain unestablished.

Home Building: Canonical GIS/CAD Register

This section is the durable source for modelling the apartment building through Ch.440; no later chapter through that point changes the Ch.359 structural register. Use GIS level 0 = Japanese 1F (ground/entrance level). Apartment numbers follow Japanese floor numbering: 1xx on 1F, 2xx on 2F, etc. Function rooms are normally labelled by use rather than as 00x rooms.

Massing and circulation

Floor and occupancy schedule

GIS level Japanese floor Established residential units and inhabitants Common/non-residential programme Unallocated / modelling notes
0 1F 102: unnamed resident couple. 105: Yoshimura, female, residents' committee organiser. Main entrance, mailboxes, lift/stair core, meeting room, emergency store, service/electrical/comms/fire/cleaning rooms, waste/recycling access and covered bicycle parking. 101 may be absent or absorbed by lobby/meeting space. 103-104 remain undefined. Ground floor may project 15-30% beyond the upper L for communal/service use; exact percentage is estimated.
1 2F 202: Thomas Albrecht and Isha Vaeloren in the large three-bedroom corner flat after the Akiyama family moves away. 203: Saitō Fumiko, older woman who uses a cane at times. 204: Miyake Natsumi, public-library worker and private book/album-repair hobbyist, resident for six years. Lift/stair landing, corridor/gallery, risers, small fire/cleaning cupboard; access to exterior stair. 201 may be absent or partly absorbed into the enlarged 202 footprint at the elbow of the L. 205-206 remain undefined. In 202, the genkan opens into a short hall: separate WC and wash/bath lie on one side and two smaller bedrooms on the other; the hall widens into an LDK with kitchen/dining at the inner elbow and living space extending along the second wing. A short passage reaches the quieter main bedroom and a deep bedding cupboard. The smallest room receives morning light. Two-aspect windows and a long balcony follow and turn around the outer wall behind a divider. Current use: main bedroom; one smaller room as Thomas's office; one deliberately flexible guest/storage/drying room. From the lower balcony, the meeting-room roof and bicycle shelter occupy more foreground than from 304. Flat 203 contains at least one old heavy low cabinet and family photograph albums; Ch.395-396 moves the cabinet to another wall without changing the flat plan. Flat 204 contains bookcases, a low worktable, cutting mat, board, brushes and a small book press; Miyake also uses removable photograph corners/interleaving/guarded or hinged pages in private album work. Exact plans remain unestablished.
2 3F 302: Fujii Masato, older retired science teacher, lives alone. 304: vacated former flat of Thomas and Isha; no current resident established. 305: Arakawa Shigeru, older widower and retired railway-maintenance worker. 306: Nakahara household—older husband using an oxygen concentrator and his wife; an adult daughter lives elsewhere and assists. Lift/stair landing, corridor/gallery, risers and exterior-stair access. 301 and 303 remain undefined. Earlier provisional placement of Fujii in 202 is rejected in favour of 302. Do not retain Thomas/Isha occupancy metadata in 304 after their handback.
3 4F 401: unnamed university student; sex, age, course and any co-residents remain unestablished. Lift/stair landing, corridor/gallery, risers and exterior-stair access. 402-406 remain undefined. Do not fill them merely to balance the plan. This is the building's highest occupied floor; do not create 5xx units or another residential floor above it.

Modelling authority

Recurring Functional Settings

These remain categories until a specific place appears repeatedly or gains continuity value.

Setting type Narrative and continuity use
Local cafés, bakeries, and restaurants Available for language practice, social meetings, food discovery, dates, and neighbourhood routine, but none is yet canonised as a regular establishment.
Unnamed central-Sendai cat-girl maid café Themed café above a stationery shop visited by Thomas alone in Ch.225 during an unassigned afternoon. It has tasteful cat-ear/cat-tail performance, clear consent/photography boundaries, good tea and cake, and a loyalty card Isha keeps as a possible future option. Useful for comedy, performance-as-choice, Earth fantasy imagery and beast-folk memory resonance; do not turn it into a secret supernatural site or recurring harem/comedy engine. Exact name and location remain unestablished.
Local station or bus stop The final neighbourhood GIS should provide a practical route to central Sendai and Sendai Station. Its identity remains open so the home district, river, and university can be chosen as one plausible spatial system.
Municipal, banking, and employment offices Make the supplied identities usable through residence administration, accounts, tenancy, insurance, and job searching. Procedures should create ordinary friction rather than conspiracy.
Other sport and activity spaces Additional pools, routes or clubs remain available, but established anchors are the campus gym, modern recurve ranges, kyūdō dōjō, former judo dojo, climbing centre, municipal athletics track and Shibata's MMA gym. Isha has completed two regulated novice MMA bouts: a second-round choke win over Morita Ayaka and, on 11 December 2027, a two-round decision loss to Naruse Kana. No third bout is established through Ch.440.
Accessible nature Parks, wooded hills, riverside vegetation, coast, and mountain routes may become recurring places of rest and comparison without turning Earth into untouched wilderness.

Home Continuity

Institutions and Material Baseline

Earth institutions interpret Thomas and Isha through ordinary explanations: accident, concussion, trauma, memory disturbance, foreign-resident paperwork, graduation and current employment. Thomas's regular university job and three-year work-status renewal, Isha's short-hours regular climbing job and one-year independent renewal, and their accepted 15 October 2027 civil marriage notification are ordinary administrative facts. Nothing currently gives officials reason to infer magic, another world or Ian. Kanno remains the deliberate private confidant, not an institution. Ian's neutral constructs, group chat, fantasy-side media and Berlin transport are external-narrative effects with no public administrative status.

Modern technology should be named normally in narration. Thomas broadly understands it; Isha does not initially, but learns tools quickly once their inputs, outputs, ownership, and risks are explained. Her unfamiliarity is most useful where technology intersects with culture, privacy, trust, etiquette, or hidden systems—not as repeated amazement at appliances.

Continuity-bearing systems include:

Exact legal, transport, opening-hour, fare, or procedural claims should be checked when a chapter depends on them.

Relevant Natural Environment

Earth ecology matters only where it shapes setting, Isha's adjustment, seasonal continuity, or a scene.

Established or recurring elements:

Do not create an encyclopaedic species list. Name a species only when identification affects the scene, recurs, reveals Isha's way of seeing, or needs continuity. Earth nature should neither be idealised as untouched nor dismissed as dead: it is altered, managed, fragmented, and still alive.
