## Chapter 262 — Saturday Rules The Saturday class began before Isha was allowed to join it. She sat against the wall with her training bag beside her and watched twelve people work through a sequence Shibata had not taught in the beginner sessions. One partner entered beneath a punch that was not thrown, drove the other toward the padded fence, changed level when the hips retreated and followed the movement into a takedown that ended against the wall rather than in the open mat. No part lasted long enough to become a technique by itself. The striker’s missing punch determined the entry. The fence changed the takedown. The failed takedown opened the body lock. The body lock created the trip. Each pair moved through the same broad sequence, but the details altered with height, stance and resistance. Isha liked it immediately. She wore the black short-sleeved rashguard and loose shorts from Tuesday. Her hair had been braided tightly enough that no pale strand reached her face. The class had already warmed the room, and the muscles along her bare arms held a fine sheen beneath the lights while she watched. Arai sat beside her for the first ten minutes, though she had attended the session before. “You are supposed to observe,” Arai said. “I am observing.” “You are moving your feet.” Isha looked down. One heel had shifted outside an imaginary stance as Kurata, the larger man currently against the fence, attempted to turn his partner. “I am observing with preparation.” “That is how Shibata describes impatience when he wants to charge membership fees for it.” Across the mat, Shibata told Kurata to stop trying to win the demonstration. Kurata replied that he was supplying realistic resistance. His partner remained folded beneath one arm and said realism could be reduced by twenty percent. The exchange loosened the room without interrupting the drill. Saturday contained people Isha had not met during the beginner classes. Some came from the gym’s amateur fight team; others trained only grappling but had enough experience to move without waiting for instruction at every stage. Mizuno was present, taping two fingers together near the equipment rack. A compact woman in a grey rashguard stretched beside her with both heels flat and her knees turned outward farther than Isha’s human joints found inviting. Arai followed Isha’s attention. “Hoshino Emi,” she said. “Very light. Do not let that become reassuring.” “What does she prefer?” “Anything that begins with you thinking you have passed her legs.” Hoshino looked up as if the warning had travelled across the mat. Her face was narrow, her dark hair cut level with her jaw. She smiled once at Isha and returned to stretching. Shibata called the first section to an end. Everyone took water. He crossed to Isha, looked at the marked invitation card resting on her bag and pointed toward the open mat. “Warm up. You join the positional rounds. No standing work yet.” Isha rose. Arai collected her own mouthguard. “Observation has been revoked.” “It was useful.” “You have watched eleven minutes.” “I learned several things.” Arai looked toward Shibata. “This is why he should have made you watch longer.” The warm-up did not treat Isha as new. She joined the final circuit of hip escapes, shoulder rolls, technical stands and short sprawls while the other class members prepared for rounds. Her body was already warm from the walk and the restrained effort of watching, but the first rapid roll pulled differently across her neck where Mizuno had choked her on Tuesday. The tenderness was nearly gone. Shibata divided the mat into three areas. The first began with one person’s back against the fence and the other controlling the clinch. The second began in half guard on the ground. The third began with one arm already threatened from side control. Each round lasted ninety seconds before the disadvantaged person changed. “Today you do not need to escape beautifully,” Shibata said to the class. “You need to recognise the problem before you solve the wrong one.” His gaze passed over Isha without stopping upon her. She began at the fence with Kurata. He was in his late thirties, perhaps ten centimetres shorter than Isha and considerably heavier. His shoulders filled the black rashguard, and one knee carried a soft brace beneath his shorts. He introduced himself, checked that Isha understood the starting pressure and placed his forehead beneath her jaw. “Tell me if the knee makes the position strange,” he said. “Which knee?” “The left.” Kurata shifted his stance to show her the brace. Isha watched where his weight settled instead. “Your right side is carrying more weight.” He looked down at his own feet. “That was fast.” The timer sounded, and he drove her into the padding. Unlike Arai, Kurata did not need Isha to make an obvious mistake before he occupied space. His weight arrived through shoulder, forehead and hips at once. One arm controlled beneath hers; the other joined behind her back before she could establish the frame Shibata had taught. Isha lowered her centre and found the wall refusing the distance she would normally create. The exposed side of Kurata’s neck offered an old answer. So did the knee brace, the fingers locked behind her and the soft place beneath the ribs where breath could be removed. She let each pass. Kurata changed level. Isha widened her stance before his hands reached the legs. He returned to the body lock and lifted just enough to reduce the usefulness of her feet. The movement was controlled, but his strength was real. For an instant her weight belonged more to his joined hands than to the mat. She threaded one arm inside, placed her forehead against his temple and turned her hips away from the stronger side. Kurata followed. The knee brace remained outside the direction of force. Isha changed again, not attacking the injured side but using the expectation that she might. His weight shifted. She stepped around him. Kurata met the fence chest-first with Isha behind one shoulder. She controlled his waist, blocked the unbraced leg and began the return to the mat. The easiest finish would have lifted him clear before turning. Shibata had prohibited neither high-amplitude throws nor strong takedowns in the class, but Kurata’s knee and the narrow distance to the wall made the answer unnecessary. Isha lowered her own weight instead. Kurata descended through a slow spiral, one hand reaching the mat before his hip followed. She stayed behind him and secured the top position. The timer sounded before he could begin the escape. Kurata sat back against the fence. “You made that polite.” “You told me about your knee.” “I did not mean you had to move me like furniture in someone else’s house.” He stood, tested the leg once and found no complaint. Shibata had watched from the centre of the mat but offered no judgement. He pointed Isha toward the half-guard station. Hoshino waited there. She was smaller than Isha had expected when standing—perhaps just above one hundred and fifty centimetres, with narrow shoulders and legs that seemed disproportionately strong when she lowered herself to the mat. Isha began on top with one leg caught between Hoshino’s. “Do not protect me from your weight,” Hoshino said. “Protect my joints from your speed.” Isha settled carefully across her upper body. Hoshino adjusted the trapped legs by a few centimetres and asked for more weight. Isha gave it. “More,” Hoshino said. The request became interesting. Isha lowered her hips and let her chest carry pressure through Hoshino’s shoulder line. The smaller woman’s breathing changed, but her frame did not collapse. The timer began. Isha worked to free the trapped leg. Hoshino turned slightly onto one side, caught Isha’s wrist and allowed the first layer of control to disappear. Isha placed her hand upon the mat to prevent the turn. The position changed beneath her. Hoshino’s upper leg climbed across Isha’s shoulder. Her lower leg withdrew from the half guard and moved behind Isha’s arm. One of Hoshino’s hands controlled the wrist while the other reached beneath Isha’s ankle. Isha understood that her shoulder had become the centre of the structure but not which direction made it safe. She could stand. She could roll forward. She could pull the arm backward before the legs closed. Each answer might escape or complete the attack for Hoshino. The smaller woman’s hips moved away. Pressure entered Isha’s shoulder slowly, rotating the joint while her posture folded. Isha tapped Hoshino’s hip. The structure opened at once. “Good,” Hoshino said. “Again.” “What was it?” “Omoplata. Shoulder lock with the legs. You put your hand on the mat where I wanted it.” Isha rotated the shoulder. Nothing hurt. “Show me the dangerous direction.” Hoshino repeated the final position without pressure and moved Isha’s arm through the line that would strain the joint. The control felt less like a lock than an entire body arranged around one shoulder. “You can roll before I flatten you,” Hoshino said. “You can posture before the leg is high. You can keep your hand away from the floor. Once I have the angle, do not test whether your shoulder is unusual.” “It is not.” “I know. Everyone says that with their face eventually.” They reset with thirty seconds remaining. This time Isha refused the first wrist control and placed her hand upon Hoshino’s sternum instead of the floor. Hoshino changed direction, underhooked the trapped leg and rolled beneath her. Isha followed too quickly. The omoplata began from the opposite side. Isha rolled forward before the shoulder closed, came onto her back and found Hoshino already sitting beside her with the arm still trapped. The timer ended before the position became another submission. Hoshino released and stood. “Faster learning. Still mine.” Isha accepted the offered hand. “For another second.” Hoshino’s grip tightened as she pulled Isha upright, the smaller woman smiling at the correction rather than disputing it. “Good. You are unpleasant.” The third station began with Mizuno controlling Isha’s arm from side position. Mizuno had taped the fingers that Isha had gripped during their previous round. The tape was preventative rather than evidence of injury. She showed Isha the starting frame: Isha on her back, right elbow separated, Mizuno’s knee near the hip and both hands controlling the wrist and upper arm. “This is already bad,” Mizuno said. “Yes.” “I am pleased we agree before you attempt to bench-press me through the ceiling.” Mizuno adjusted Isha’s wrist and left the shoulder only just short of pressure. “I did not do that last time.” “You considered several things last time.” The timer began. Mizuno drew Isha’s wrist toward the floor above her head. Isha followed the motion enough to prevent the shoulder from becoming fixed and turned toward Mizuno rather than away. Mizuno changed to a bent-arm grip, using Isha’s own elbow as a lever. The position resembled an old break applied before interrogation, except that Mizuno left space for movement and increased pressure in a line that announced itself. Isha bridged. Mizuno rode the movement and changed her knee position. Isha recovered one forearm between them but lost the trapped arm farther from her body. She could strike, bite or turn Mizuno’s fingers. She could also accept that the starting position had been chosen because all safe escapes were late. She made space at the hip, brought one knee inside and forced Mizuno to choose between the arm and the position. Mizuno kept the arm. Isha turned with the control, came onto her knees and began to stand. Mizuno followed beneath her shoulder, maintaining the bent-arm grip. The pressure changed from shoulder rotation to balance. Isha could have lifted Mizuno from the floor by straightening. She stepped over Mizuno’s body instead and turned into the grip. The arm came free. Mizuno caught one leg before Isha could settle and drove forward, returning them to the mat with positions reversed. The timer sounded. Mizuno remained across Isha’s hips for a breath. “You escaped,” she said. “You changed attacks twice.” “And you changed problems three times.” Mizuno stood and offered her hand. Shibata called water before the full live rounds. Isha drank beside the wall, pulse elevated but breathing steady. Sweat had loosened one braid near her neck. Around her, Kurata was explaining to another man how she had avoided his braced knee. Hoshino sat cross-legged, demonstrating the omoplata entry with Arai’s arm. Mizuno retaped one finger where the edge had lifted. Arai joined Isha and drank from her bottle. “Hoshino got you.” “Yes. I did not enjoy the pressure, but I learned what it was.” “You smiled afterward.” Arai looked toward Hoshino, who was folding Arai’s arm into the same trap. “That is close enough to enjoyment here.” Shibata announced four-minute rounds. Standing starts for selected pairs; ground starts for everyone else. No strikes. Takedowns were to remain controlled. He assigned Isha to Kurata first, Hoshino second and Mizuno last. Arai made a quiet sound of sympathy. “Are these the people who make me wrong in different ways?” Isha asked. “Yes. Shibata has become organised.” The first live round began standing. Kurata no longer offered the fence position in advance. He used short hand-fighting, changed levels without committing and forced Isha to distinguish a true entry from movement intended to draw her defence. His injured knee remained protected by his stance, but he did not ask Isha to avoid it now that both understood the limit. He reached one leg. Isha sprawled and moved behind. Kurata rose through the pressure, caught her waist and carried the exchange to the fence. The padding trembled as their combined weight reached it. Isha reversed him once. He reversed her back. She threatened the outside trip; he withdrew the foot and took the inside position instead. No single movement ended the contest. Kurata attempted to lift. Isha widened her base, threaded one arm inside and found his balance divided. She could throw him hard enough that the room would remember it. The opening felt clean, familiar and satisfying. She released it. Kurata expected the throw and braced against the wrong direction. Isha changed to the quieter trip, lowered him beside the fence and followed into top position. He recovered half guard almost immediately. The trapped leg slowed her, and his upper body remained strong enough to make pressure expensive. Isha applied what Hoshino had shown her, keeping the hand away from the mat and placing weight through the shoulder line. Kurata tried to roll beneath her. Isha followed, freed the knee and moved to side control. From there she found the near arm isolated. The old break required one movement. The sport arm lock required a grip she had practised only slowly. She took the wrist, controlled above the elbow and began the taught rotation. Kurata tapped before the angle became painful. Isha released and moved away at once, and they reset standing with forty seconds remaining. “You found a legal one,” Kurata said. “Yes.” Isha settled her stance again while he tested the freed arm. “Try not to look disappointed.” Kurata’s arm moved normally when he reset the grip, though his expression suggested he intended to preserve the accusation. “I am not.” The remaining exchange ended with Kurata holding her against the fence when the timer sounded. Neither tried to convert the final seconds into proof. Hoshino’s round began seated. Isha started outside the smaller woman’s legs. Hoshino offered one foot near the hip and one hand within reach, both invitations too obvious to accept. Isha moved around them. Hoshino followed on her back, shoulders barely leaving the mat while her legs reorganised the space. The first pass attempt failed. The second reached Hoshino’s side until one shin recovered the gap. On the third, Isha controlled both knees, stepped around and lowered her weight before Hoshino could rebuild the frame. Hoshino gave up the side position too easily. Isha recognised the trap one moment after entering it. Hoshino caught her arm, turned beneath and began the same shoulder structure from a different angle. Isha rolled before the legs closed and landed beyond Hoshino’s hips. The smaller woman followed, sat up and attached herself to Isha’s back. One forearm reached beneath Isha’s chin. Isha caught the wrist with both hands and placed her shoulders against the mat before the second arm could secure the choke. Hoshino changed to an arm attack. Isha turned into her, freed the elbow and came on top. The exchange accelerated. Hoshino threatened the shoulder again. Isha withdrew. Hoshino used the withdrawal to recover her legs. Isha stepped over one, was pulled forward by the other and found herself balancing above a trap whose final shape she did not know. She stopped trying to predict the submission and controlled Hoshino’s hips instead. For several breaths neither advanced. Hoshino’s legs continued testing angles. Isha’s weight followed each attempt while refusing to cross into the same dangerous line. She passed with less speed than before and reached side control with one minute remaining. Hoshino framed against her neck. Isha held the position. The smaller woman shifted, bridged, turned and attempted to bring a knee inside. Isha adjusted without crushing her flat. The round ended there, Isha above and Hoshino still working. Hoshino lay back after the timer. “You became boring.” “It prevented the shoulder lock.” “Yes. Very inconsiderate.” She accepted Isha’s hand and rose. Mizuno waited for the final round with her mouthguard already in place, and Shibata told them to begin standing before moving close enough to intervene. Mizuno attacked first. She reached the body, changed to one leg and drove Isha toward the open mat rather than the wall. Isha sprawled, but Mizuno had expected the defence and turned the corner before her hips settled. They fell with Mizuno above one leg. Isha framed, recovered space and stood before the position stabilised. Mizuno remained attached, climbed to the waist and attempted to return her to the mat. Isha turned within the grip. The resulting clinch lasted longer than either of their previous standing exchanges. Mizuno had learned the timing of Isha’s sweeps; Isha had learned that Mizuno used apparent imbalance to draw the attack. Each woman found openings that had already become warnings. Mizuno pulled Isha forward and dropped beneath her. Her legs climbed toward the triangle that had caught Isha during the first live class. Isha kept both arms inside, postured and turned before the structure closed. Mizuno changed to the shoulder lock Hoshino had demonstrated earlier. The transition almost worked because Isha recognised it late. She rolled, came up beside Mizuno and found her back exposed. Isha placed the first hook, controlled one wrist and reached beneath the chin. Mizuno protected the neck. Isha adjusted to the legal grip Shibata had shown, using her chest and hips to remove space rather than pulling with the arms. Mizuno’s defence held. Isha could force the chin upward. She could crush the jaw, twist the head or turn the neck until the hands separated. None were needed. She retained the back position and waited for Mizuno to make the next decision. Mizuno tried to turn into her. Isha followed and tightened the safe choke as the chin lifted. The tap landed against Isha’s forearm. She released before Shibata moved, and they separated to kneel facing one another. Mizuno removed her mouthguard. “That one was correct.” “Yes.” “You took a long route.” “It was the route I knew was safe.” Mizuno fitted the mouthguard again. “Then next time take it sooner.” They reset with more than a minute remaining, and Mizuno submitted her before the end. The attack began from a failed takedown, continued through a front headlock and became a choke whose pressure arrived only after Isha believed she had escaped the first grip. Her own arm was trapped beside her neck. Mizuno’s chest closed the remaining space while her legs prevented the turn. Isha tapped, Mizuno released immediately, and the timer sounded before they could reset. Both women remained on their knees, breathing deeply. Mizuno’s face had reddened across the cheeks. Sweat ran from Isha’s braids onto the front of her rashguard. Neither looked finished. Shibata looked between them. “Good. You each found the reason the other one returns.” The sentence was almost polished enough to irritate Isha. Mizuno corrected it by saying, “I return because membership has already charged my card.” The room laughed and began the final bow. --- Shibata asked Isha to wait after the mats had been wiped. The Saturday group dispersed toward showers, vending machines and afternoon obligations. Hoshino left with a canvas bag that seemed too large for her. Kurata remained long enough to stretch the braced knee and tell Isha it felt no different than before the class. Shibata sat on the edge of the reception desk with Isha’s membership record open on a tablet. “How much do you weigh?” he asked. Isha gave the recent figure from the climbing centre’s health check. He entered it. “Stable?” “Yes.” “Any reason you cannot pass an ordinary sports medical?” “No.” The questions were too specific to concern Saturday attendance alone. Isha stood opposite him with her damp training shirt beneath one arm and waited. Shibata noticed the waiting. “I am not offering you a match.” “You have said that before.” “I will continue until you stop hearing every question as preparation.” He set the tablet down. “If I eventually thought a beginner one-match was appropriate, would you want me to tell you?” The answer came before she needed to examine it. “Yes.” Shibata studied her face. “Why?” “I want to know what the rules become when the other person is trying to win.” “They are still rules.” Shibata picked up the tablet again, giving the reminder more weight than the object required. “I know.” “You know in the calm part of training. I need to know whether you remember when someone hits you hard, when a referee is in the way and when you are tired enough that the wrong answer feels simpler.” Isha thought of Mizuno’s choke, Hoshino’s shoulder lock and the clean opening against Kurata that she had chosen not to use. “Then watch for that,” she said. “I am.” He closed the record. “For now, Tuesday striking. Saturday again next week. No match discussion until I raise it.” Isha accepted the limit and went to shower. --- Arai gave her the bruise on Tuesday. The striking class had moved beyond fixed combinations into short technical rounds: two minutes of controlled punches and low kicks, followed by a clinch entry if either fighter reached the wall. They wore large gloves, mouthguards and shin pads. The intensity was high enough that mistakes had consequences and low enough that no one intended damage. Isha’s defence had improved. She read shoulders before gloves, checked several kicks and used smaller movements than during her first visit. Arai’s jab found her less often. The cross reached her guard rather than her face. That success changed Isha’s expectation. Arai stepped left, showed the jab and turned a short right hook behind it. Isha recognised the opening for the clinch and moved inward before the hook had finished travelling. The glove caught her beneath the left eye. It was not a hard strike. Isha’s own movement supplied part of the impact. Her head turned, the lights shifted by a fraction and the clinch opening vanished. She stepped back with both hands raised. Arai stopped immediately. “Vision?” “Clear.” Shibata was already beside them. He checked her eye, asked about nausea and had her follow one finger through several directions. The skin beneath the cheekbone had begun to redden. “You entered before the second hand was accounted for,” he said. “Yes.” “You saw the clinch and stopped seeing the punch.” Shibata checked the reddening skin once more, then stepped back. “Yes.” He looked at Arai. “Lower pace. Continue only if both agree.” Arai asked Isha directly. Isha wanted the round, and they resumed. The same sequence appeared again forty seconds later. This time Isha let the hook pass, closed the distance afterward and placed Arai against the wall with her balance intact. The correction pleased her more than avoiding the bruise would have. By the end of class, colour had gathered beneath the eye in a narrow violet shadow. It did not affect vision, movement or speech. Shibata checked once more before allowing her to leave and instructed her to seek medical attention if pain, swelling or visual symptoms developed. Arai apologised despite having done nothing outside the agreed round. “You struck correctly,” Isha said. “I struck lightly.” “I moved into it correctly enough to make the result larger.” Arai examined the bruise with professional dissatisfaction. “Thomas is going to think I attacked you.” “He knows I attend a gym where people strike me.” “That sentence will not improve the first impression.” --- Thomas saw the bruise before Isha removed her shoes. He had come into the genkan carrying a clean towel, expecting only the usual damp hair and training bag. His attention fixed beneath her left eye. He stopped close enough to inspect it without touching. “Vision?” he asked. “Clear. No nausea, headache or dizziness. Shibata checked twice.” Thomas’s shoulders lowered slightly. “What hit you?” “Arai’s right hook. I moved toward it.” “That seems cooperative beyond the purpose of training.” “It was an error.” Isha stepped out of her shoes and handed him the bag. “A useful one.” Thomas carried the bag to the utility space while she washed her hands. When she entered the LDK, a cold pack wrapped in a thin towel waited beside a cup of tea. She sat. Thomas placed the pack gently beneath her eye and watched for discomfort. The cold hurt more than the bruise. Isha kept it there because his concern had remained proportionate and because the pressure reduced the swelling Shibata had warned might appear overnight. “I will probably be less calm when there is an actual contest,” Thomas said. “There is no contest.” “I know. This is advance notice rather than an objection.” He sat beside her, one hand resting on her knee. “I am happy that you like it. I am also likely to dislike watching someone try to hit you properly.” Isha leaned against his shoulder, holding the cold pack in place. “You do not have to like that part.” “I may attend while disliking it.” “Yes.” They remained there until the pack grew less cold. Thomas asked about Saturday rather than returning to the bruise. Isha described Kurata’s wall pressure, Hoshino’s shoulder lock and the final exchange with Mizuno. She demonstrated the position of her trapped arm in the air, then stopped because the absence of another body made the explanation useless. Thomas watched her arrange imaginary limbs. “You can show me.” Isha lowered her arm. “The shoulder lock?” “Perhaps begin with something less likely to make tomorrow’s university meeting difficult.” He looked toward the flexible room. “You said you needed practice pinning people safely.” “I said no such thing.” “You corrected my previous offer by saying pinning was not the part you needed to practise.” Thomas’s mouth shifted at one corner. “I have reconsidered the available role.” The invitation remained playful, but he had waited until she was uninjured, fed and sitting beside him rather than using concern to produce permission. Isha placed the warming cold pack upon the table. “No pressure on your neck,” she said. “No joint locks. Tap twice or say stop.” “I had expected an informal demonstration.” “You offered practice.” Thomas looked toward the flexible room again. “I should have negotiated before the rules were written.” They moved the folded duvet aside and used the exercise mats already protecting part of the floor. Thomas changed into an old T-shirt and training trousers. Isha remained in the fitted black rashguard and shorts from class, her skin still warm from the shower, the bruise darkening beneath one eye. She knelt beside him. “Lie on your back.” Thomas obeyed with the care of someone who knew obedience could become comedy if acknowledged too early. Isha settled across him in side control, chest perpendicular to his, one arm beneath his head and her hips low beside his ribs. She did not place her full weight upon him. Thomas tested the position by pushing at her shoulder. Nothing useful happened. “Am I meant to move you?” he asked. “You may try.” He pushed harder. Isha followed the pressure rather than resisting it directly, shifting a few centimetres while keeping his shoulders controlled. Thomas attempted to turn onto one side. Her knee occupied the space before he reached it. He tried the other direction and found her hip blocking the movement. “You are not heavy enough for this to feel as impossible as it does.” “Weight is only useful where it is placed.” “That sounds like something Shibata would say before charging extra for Saturday.” Isha laughed. The movement loosened her control for an instant. Thomas bridged beneath her and created enough space to bring one forearm between them. “Better,” she said. His satisfaction lasted until she changed position. Isha slid one knee across his body and settled astride his hips. The rashguard drew close over her waist and chest as she leaned forward to control his wrists against the mat. Pale braids fell over one shoulder. The bruise beneath her eye made the beauty above him look less delicate and more immediate, a mark gained through a choice she had enjoyed making. Thomas stopped attempting to escape. Isha looked down at him. “You have abandoned the drill.” “I am reassessing its purpose.” “You offered to be pinned.” “I did not anticipate the instructor’s clothing.” She tightened her grip only enough to confirm that his wrists remained where she had placed them. His pulse moved beneath her fingers. “Do you want me to move?” she asked. Thomas considered the question with visible seriousness. “Not immediately.” Isha bent and kissed him. The cold pack slid from the edge of the mat where Thomas had left it and landed quietly beside them. Neither reached for it.
