Chapter 6: First Session
His alarm went off at 5:30 AM.
He'd slept maybe two hours. The rest of the night was spent lying on the futon with the system's knowledge database open like a floating textbook in the dark going through everything he could find on the Straw Doll Technique.
The system didn't have a manual for teaching. What it had was raw data. Technique descriptions. Cursed energy flow patterns. Theoretical frameworks for technique evolution.
Most of it was above his comprehension level. He wasn't a sorcerer. He couldn't feel cursed energy let alone manipulate it. But he could read. He could analyze. And he could take concepts from a manga he'd read cover to cover dozens of times and translate them into something practical.
He hoped.
He splashed water on his face in the small bathroom attached to his room. The mirror showed the same unfamiliar face. Dark eyes with shadows under them now. Messy hair. Skinny shoulders.
He put on the cleanest clothes he could find from the previous owner's sparse wardrobe. A black long sleeve shirt and dark pants. Functional. Boring.
Then he grabbed the Gojo sunglasses from the desk and put them in his pocket. Just in case.
The training grounds at six AM were beautiful.
The morning sun cut through the tree line in golden shafts. Mist hung low over the dirt field. Birdsong filled the gaps between the sound of wind.
Nobara was already there.
She stood in the center of the training area in full combat gear. Jujutsu uniform. Hammer in her right hand. Nails held between the fingers of her left hand like metal claws. Her hair was pulled back into a short ponytail that exposed the line of her neck and jaw.
She looked like she was ready to kill something.
Possibly him.
"You're late." She tapped the hammer against her thigh.
"It's 5:58."
"I said six. If you're not early you're late."
He decided not to argue with the girl holding a hammer. "Fair enough. Should we start?"
"Start what exactly?" She planted the hammer head on the ground and leaned on the handle. "You said you know about resonance chaining. So talk."
Haruto took a breath. This was it. If he couldn't deliver on what he'd promised last night he was done. The system would deactivate. He'd be a zero cursed energy nobody with no protection in a world full of monsters.
"Your Straw Doll Technique." He started pacing. Not nervously. Deliberately. The way a coach walks a sideline. "The core mechanic is sympathetic cursed energy transfer. You establish a link between a proxy and a target. What you do to the proxy happens to the target."
"I know what my own technique does."
"You know what it does NOW. Not what it CAN do." He stopped pacing and faced her. "When you use Resonance on a target through a proxy what happens to the cursed energy flow?"
She frowned. "It transfers from me through the straw doll to the target. One direction. One target."
"Right. One direction. But cursed energy isn't unidirectional by nature. It wants to cycle. Flow and return. Your technique forces it into a straight line but the energy itself is fighting you the entire time."
Nobara's frown deepened. Not confused. Processing.
"If instead of forcing a one way transfer you allowed the cursed energy to loop back through the connection you could create a sustained resonance. Not a single hit. A continuous effect."
"That would mean keeping the link open. That takes concentration and—"
"And more cursed energy. I know. That's why you need to practice efficiency." He walked closer. Carefully. "Right now you're using your cursed energy like a firehose. Full blast. One direction. What if you used it like a river? Constant flow. Self sustaining."
She stared at him. The hammer dangled loosely in her grip.
"You're not wrong." She said it like the words physically hurt. "I have thought about sustained resonance before. But every time I try to keep the link open it snaps after three seconds."
"Because you're trying to hold it with force. You need to hold it with rhythm."
"Rhythm."
"Like a heartbeat. Pulse the energy instead of streaming it. Each pulse reinforces the connection. The gaps between pulses let the link settle. Over time you can extend the duration from three seconds to thirty. Eventually minutes."
Nobara was quiet for a long moment. Her eyes were focused on something internal. Running the theory through whatever instinctive understanding she had of her own technique.
Then she turned and walked to a wooden training dummy at the edge of the field. She pulled a nail from between her fingers and pressed it into the dummy's surface.
"Stand back."
He stepped back. Way back.
Nobara pulled a straw doll from her belt and held it in her left hand. Her hammer came up in her right. She closed her eyes.
He could feel it. Even without cursed energy he could feel the shift in the air. Like the temperature dropped half a degree. Like the molecules around her got tighter.
She brought the hammer down on the straw doll.
The wooden dummy cracked. A visible line split down its torso.
But this time Nobara didn't let go. Her eyes stayed closed. Her jaw clenched. The hammer stayed pressed against the straw doll and the connection stayed open.
One second. Two seconds. Three—
The dummy cracked deeper.
Four. Five—
The connection snapped. Nobara stumbled forward a step and caught herself. She was breathing hard. Sweat had appeared on her forehead despite the cool morning air.
But her eyes were wide.
"Five seconds." She looked at the dummy. The crack ran from its head to its base. Deeper than anything a single resonance should have done. "That was five seconds of sustained resonance."
"Two seconds longer than your previous best."
She turned to look at him. For the first time since they'd met the hostility in her expression was gone. Replaced by something raw and unexpected.
Excitement.
"Do that again." She grabbed another nail. "Explain the pulse rhythm thing again."
"You want to try immediately?"
"Did I stutter? Again."
They worked for two hours.
By the end of it Nobara could sustain resonance for eight seconds. Not consistently. She managed it twice out of maybe fifteen attempts. But the improvement was measurable and she knew it.
She was drenched in sweat. The uniform jacket had come off after the first hour leaving her in the fitted black undershirt that clung to her body with moisture. Her ponytail had half collapsed with strands of orange brown hair sticking to her cheeks and neck.
She sat on the bench drinking from a water bottle and staring at nothing.
Haruto sat on the ground a few feet away. Exhausted despite not having done anything physical. Coaching was its own kind of draining.
"Hey." Nobara's voice was different. Quieter. Less barbed.
"Yeah?"
"How did you know about the resonance evolution? Seriously."
"I can't explain it. Not yet."
"That answer is going to stop working eventually."
"I know."
She was quiet. Then she did something unexpected. She held out the water bottle.
"Here. You look like you're going to pass out."
He took it. Their fingers brushed. Hers were calloused from years of hammer work. Rough against his soft civilian hands.
She pulled her hand back quickly. Wiped it on her pants.
"Don't read into that. You just look pathetic and I'm not carrying you to the infirmary."
"Wouldn't dream of it."

Haruto allowed himself a small internal celebration. Almost twelve hundred points. Enough for multiple gacha pulls. And two bond levels unlocked in less than twenty four hours.
"Same time tomorrow?" He asked.
Nobara stood up. Stretched her arms above her head. The black shirt rode up just enough to show a line of toned stomach before she pulled it back down.
"Six AM. Don't be late."
She walked away. Hammer over her shoulder. Not looking back.
But she was going to come back tomorrow. That was the important thing.
He had twelve hours until Maki's session.
He spent four of those hours in his room planning. Two hours eating everything the kitchen had because his body was running on fumes. Three hours walking the campus to understand the layout.
And one hour doing something the system recommended.
[SYSTEM RECOMMENDATION: HOST SHOULD PERFORM BASIC PHYSICAL TRAINING TO AVOID DYING FROM MILD EXERTION.]
[SUGGESTED ROUTINE:] [5 PUSHUPS] [10 SQUATS] [30 SECOND PLANK]
[THIS IS THE MINIMUM HUMAN STANDARD. HOST IS CURRENTLY BELOW IT.]
He managed three pushups before his arms gave out. Seven squats before his legs burned. And a twelve second plank that made him genuinely consider whether death was preferable.
[PHYSICAL TRAINING COMPLETE (PARTIAL)]

[SYSTEM NOTE: THAT WAS GENUINELY EMBARRASSING.]
"Thanks."
[HOST IS WELCOME.]
Eleven PM.
The campus was dark and quiet. The first years were in their rooms. Gojo was somewhere being Gojo. The night staff patrolled the outer perimeter but the training grounds were empty.
Empty except for Maki.
She was waiting. Same clothes as last night. Black leggings. Gray tank top. But this time the naginata was replaced by a standard katana. She sat on the bench with the blade across her knees cleaning it with a cloth.
She didn't look up when he approached.
"You trained Kugisaki this morning."
"You heard about that?"
"She told Itadori. Itadori told everyone. The boy has no concept of secrecy." She set the cloth down. "She said you improved her resonance duration by five seconds."
"Two seconds consistently. Five was a peak."
Maki looked at him. Something in her expression had shifted from last night. The hostility was still there. The wariness. But underneath it there was a new layer. Curiosity that she was trying very hard to hide.
"Sit." She gestured to the bench next to her.
He sat. Kept a respectful distance between them. About two feet.
"Tell me about Toji's Heavenly Restriction." No preamble. No small talk. Maki cut to the point like she cut through curses.
"What do you want to know?"
"Everything."
Haruto organized his thoughts. This was different from Nobara. With Nobara he was teaching technique refinement. With Maki he was dealing with something fundamental. A body condition. A birthright that she'd been punished for her entire life.
"Toji Fushiguro reached a state where his body completely rejected cursed energy. Not just zero production. Active rejection. His physical body became so perfectly optimized that cursed energy couldn't even exist near him."
"I know the theory." She was looking at the katana in her hands. "But I also know that what Toji had... it destroyed everything else. His family. His relationships. His humanity."
"That doesn't have to be your version."
She looked at him sharply.
"Toji's Heavenly Restriction was unconscious. It happened TO him. He never trained it. Never developed it. He was born at the peak and spent his life wasting it." Haruto leaned forward. "You're different. You've been fighting your way up from the bottom. Every ounce of strength you have you earned. If you could trigger the full restriction consciously you wouldn't just match Toji. You'd surpass him. Because you'd have the strength AND the discipline."
Maki was very still.
"How." One word. Loaded.
"Physical stress training. Not normal training. Training that pushes your body to the absolute edge. Your Heavenly Restriction responds to trauma. Not emotional trauma. Physical. Your body recognizes threats and compensates by pulling more from the restriction. Every time you push past your limit the restriction opens a little more."
"I push past my limits every day."
"You push past normal limits. I'm talking about the kind of training that would kill a regular person. The kind that forces your body to choose between dying and evolving."
"And you think you can design that training?"
"I think I can guide you through it. Yes."
She studied him for a long moment. The night air was cool around them. Crickets sang in the distant trees. The floodlight buzzed softly.
"You're not what I expected." She said it quietly. Almost to herself.
"What did you expect?"
"Some kid playing at being important. Throwing around knowledge he doesn't understand to impress people." She set the katana aside and turned toward him slightly. Her knee was close to his on the bench. Not touching. But close. "But you actually understand the theory. Better than most sorcerers I've met."
"I just—"
"Don't ruin it by being modest. I hate modest people."
He closed his mouth.
She stood up. Picked up the katana. Rolled her shoulders.
"Show me." She moved to the center of the training area. "Design a training sequence. Right now. Based on what you just said."
He stood. Walked to the edge of the training area. Thought for ten seconds. Then started.
"Thirty second full sprint across the field. The moment you stop immediately transition into vertical jumps. Maximum height. Ten of them. Then weapon forms. The heaviest weapon you have. Full speed no breaks until your arms physically can't lift it anymore."
She stared at him. "That's—"
"Extreme. I know. Your body needs to hit the wall. Hard. And then you need to keep going past it. That's where the restriction opens."
She was quiet for three seconds.
Then she ran.
The sprint was inhuman. She crossed the fifty meter field in under four seconds. Stopped on a dime. Launched into vertical jumps that took her three meters off the ground. The impacts when she landed cracked the packed dirt.
She grabbed a heavy iron training sword from the equipment rack. Eight kilos at least. Swung it like it weighed nothing.
For the first ten minutes.
By minute fifteen the swings slowed. By minute twenty her arms were shaking. By minute twenty five she was gritting her teeth so hard Haruto could hear it from across the field.
"Keep going." He called out. "You're not at the wall yet."
She snarled at him. Actually snarled. Like a wild animal being pushed into a corner.
But she kept going.
Minute twenty eight. Her arms dropped. The iron sword hit the dirt. She stood there swaying. Chest heaving. Every muscle in her body trembling.
"Pick it up."
"I can't—"
"Pick it up."
She looked at him with something between rage and desperation. Her glasses had fogged with exertion. Sweat ran down her face and neck and arms in streams.
She picked it up.
Two more swings. Ugly. Graceless. Nothing like the beautiful forms from last night.
Then she collapsed.
He ran to her. Or shuffled quickly which was the best his body could do. She was on her hands and knees in the dirt breathing in ragged gasps. Her arms shook so badly they could barely support her weight.
"That's enough." He knelt next to her. "That's the wall. That's where it starts."
She looked at him from behind fogged glasses. Hair plastered to her face. Tank top soaked through entirely.
"I couldn't... feel anything change."
"Not tonight. But tomorrow your body will adapt. And the day after it will adapt again. Each time the wall gets a little further away and the restriction opens a little wider."
She sat back on her heels. Let her hands fall to her thighs.
"You pushed me harder than anyone ever has." She said it between breaths. Not angry. Not grateful. Just stating a fact.
"Is that okay?"
She looked at him. Pulled her glasses off and wiped them on her shirt. Without the glasses her face was different. Softer somehow. The sharp edges were still there but there was something vulnerable about Maki Zenin without her armor.
"Don't stop." She put the glasses back on. The armor returned. "Same time tomorrow. Push harder."
She stood up. Wobbled. Caught herself.
He reached out instinctively. His hand caught her elbow. Just for a second. Just enough to steady her.
She looked at his hand on her arm. Then at his face.
He let go immediately. "Sorry. You were—"
"I know what I was." She turned and walked toward the building. Slowly. Exhausted in a way she probably hadn't felt in years.
At the door she stopped. Didn't turn around.
"Haruto."
First name. Not "civilian." Not "you." His name.
"Thank you."
She went inside.

Haruto sat on the bench in the dark.
The floodlight buzzed. The crickets sang. The mist crept back across the training grounds covering the cracks Maki's landings had left in the dirt.
He looked at his hand. The one that had touched her arm.
He could still feel the warmth.
"Focus." He whispered to himself. "You're here to save people. Not to..."
He didn't finish the sentence.
