The Training Field
"That went well!" Gojo beamed as they walked onto the grassy training field under the midday sun. "You melted Cathy. Yaga loved Cathy."
"I didn't mean to," Miyuki whispered, looking at her hands. They were trembling. The green glow pulsed faintly beneath her skin. "I just wanted it to stop."
"Alright, Lesson One," Gojo clapped his hands. "You know the theory. Zeno's Paradox. Infinity. My Blue is attraction, Red is repulsion. Yours will be similar, but your energy is 'dirty'. It's corrosive."
He pointed to a large wooden training dummy.
"Try to use the Lapse technique. Green. Just lift the dummy. Don't melt it. Don't crush it. Just lift."
Miyuki focused. She visualized the space. Grab. Lift. She released the energy.
Cursed Technique Lapse: Green.
A sphere of emerald light formed around the dummy. It shot upward into the sky with a sonic boom, shattering into a million splinters instantly.
"Too strong!" Gojo laughed.
"I tried to be gentle!"
"Again. On that rock."
Miyuki tried again on a boulder. Gentle. The boulder dissolved into green sludge.
"Again."
This went on for hours. Lift and destroy. Push and melt. By late afternoon, Miyuki collapsed onto the grass, gasping for air. Her body felt completely drained, despite the sugar.
"I can't," she choked out. "I can't control it. It just wants to destroy."
Gojo walked over and stood over her, blocking the sun. His expression was unreadable behind his blindfold.
"It's because you're afraid of it," he said quietly. "You're treating your power like a disease. You're tensing up, holding it back, so when it finally comes out, it explodes."
He crouched down.
"The Six Eyes showed you the truth, Arima. The 'normal' world is a lie painted over a canvas of curses and death. You can't go back to being a librarian. You have to accept what you are now."
"And what am I?" she whispered, tears leaking from behind her sunglasses.
Gojo smiled, a genuine, terrifying smile. "A monster. Just like the rest of us."
He offered her a hand.
Miyuki stared at it. It was a hand that had killed thousands of curses. A hand that held the world in balance. Then, with a groan of frustration, she swatted his hand away and shakily pushed herself to her feet.
"I hate you," she said.
"I know," Gojo grinned. "Let's go again."
That Night – The Dorm Roof
Miyuki sat on the roof, knees pulled to her chest, Soseki curled asleep on her lap. The night air was cool. She still wore the round sunglasses, afraid to take them off even in the dark.
"Yo! Arima-san!" Miyuki jumped slightly. The door swung open, and Itadori Yuji stepped out. He was holding two cold cans of soda. He wore a casual hoodie, his pink hair messy in the wind. He looked surprisingly cheerful for someone who had literally died twice.
"Sorry, did I scare you?" Yuji asked, scratching the back of his neck. He walked over and offered her a can. "Peach soda. It helps with the fatigue." Miyuki took it cautiously.
"Thank you, Itadori-kun."
"Just Yuji is fine," he smiled, sitting down on the concrete ledge a respectful distance away. He looked at Soseki. "Does he bite?"
"Only Gojo," Miyuki replied, cracking open the soda. Yuji laughed, a warm, resonant sound.
"Yeah, Sensei has that effect on people. I heard explosions all afternoon. He's really putting you through the wringer, huh?"
"He's a tyrant," Miyuki muttered, taking a sip. The sugar hit her system, giving her a brief moment of clarity. "I don't understand how you all trust him. He's reckless. He's terrifying."
Yuji's smile faded slightly. He looked up at the stars, his expression turning thoughtful.
"He is," Yuji agreed softly. "But he has to be."
Miyuki looked at him. She sensed the heavy, dormant energy within the boy. It wasn't malicious, but it was scarred.
"Fushiguro-kun mentioned... Sukuna," Miyuki tested the name. She saw Yuji flinch, a visible shudder going through his shoulders. "He said Gojo fought him. That he nearly died."
Yuji gripped his soda can. The metal creaked under his fingers.
"Sukuna... was inside me first," Yuji said, his voice low. "I was his first vessel. I brought him back into this world."
Miyuki froze.
"But when they fought..." Yuji's voice cracked. He stared at his hands as if they were stained. "When Gojo-sensei fought him in Shinjuku... Sukuna wasn't in my body anymore. He had taken over Megumi."
Miyuki's eyes widened behind her sunglasses. "Fushiguro-kun?"
Yuji nodded, pain etched into his face. "Sukuna stole Megumi's body to use his technique against Sensei. So when Gojo-sensei was fighting for the fate of the world... he wasn't just fighting a monster."
Yuji looked at Miyuki, his eyes filled with a raw, honest pain.
"He was fighting his own student. He had to look at Megumi's face while Sukuna tried to kill him. He had to destroy the boy he raised just to kill the curse inside him."
Miyuki remained silent, the wind rustling her hair. The horror of it settled in. The playful man she met that morning had fought his own adopted son to the death.
"I saw him bleeding, Arima-san," Yuji whispered. "Gojo Satoru, the man who never gets touched... he was cut open. He was lying in a pool of his own blood. And in that moment, I felt a fear I can't even describe. It wasn't just fear of dying. It was the fear of a world without him."
"But he got up," Yuji's voice grew stronger, though tears pricked the corners of his eyes. A fierce pride burned there. "He clawed his way back from the afterlife. He healed himself. He saved Megumi, and he saved us."
Yuji turned to her, his expression earnest.
"He smiles like that and acts like a goofball, so we don't carry that weight. He carries the weight of the entire sky so we can just... be students. Even if it's just for a little while."
Miyuki looked down at the peach soda in her hands. "Does it ever get easier? Knowing what's out there?"
Yuji thought for a moment. Then he grinned, that signature sunshine smile breaking through the gloom, though it didn't quite reach his eyes this time.
"I don't know if it gets easier. But the food still tastes good. And friends are still funny. And cats are still cute." He reached out and gently poked Soseki's ear. The cat didn't hiss; he purred.
"Survival isn't just about not dying," Yuji said. "It's about making sure there's someone left to eat meatballs with when it's over."
He stood up, stretching his arms.
"You should sleep! Nobara is coming for you tomorrow. And trust me, Kugisaki is scarier than Sukuna when she's shopping."
"So I've been warned," Miyuki managed a small, tired smile.
"Night, Arima-san!" Yuji waved and headed back inside.
Miyuki watched him go. He was so bright. So impossibly kind despite the guilt he carried.
She stroked Soseki's white fur.
"If he can do it," she whispered to the cat, "maybe we can too."
*
Saturday in Tokyo was usually a dream for a civilian. For Arima Miyuki, it was a tactical nightmare.
She stood at the entrance of Takeshita Street in Harajuku, wearing her new round sunglasses. To anyone passing by, she looked like a stylish, if somewhat pale, woman. To Miyuki, the crowd wasn't just people; it was a river of biological data. She saw heart rates, dopamine levels spiking from crepe consumption, and the faint, grey smog of minor stress-curses clinging to the shoulders of exhausted tourists.
"Stop standing there like a statue," Kugisaki Nobara commanded, grabbing Miyuki's arm. "We have a mission."
"Mission?" Miyuki asked, clutching her purse. "Gojo didn't mention a mission."
"The mission is you," Nobara pointed a manicured finger at Miyuki's chest. "You're wearing a cardigan that has a hole in the elbow. You look like a depressed librarian. If you're going to be walking next to me, you need to look the part."
Miyuki looked down at her clothes. "But... I am a depressed librarian."
"Not anymore," Nobara grinned, terrifying and sharp. "Now you're a sorcerer. And sorcerers have style. Let's go."
Nobara dragged her into the crowd.
The Shopping Spree
The next three hours were a blur of fabric and changing rooms. Nobara was ruthless. She rejected florals ("Too weak"), she rejected pastels ("You're not five"), and she absolutely banned beige ("You blend into the wall").
"Try this," Nobara threw a black turtleneck and a high-waisted, emerald green skirt at her. "It matches your eyes. The creepy glowing ones."
Miyuki sighed and went into the changing room. She pulled the curtain shut. For a moment, she leaned against the mirror, taking a deep breath.
The sunglasses helped, but the city was still loud. The hum of electricity in the walls, the vibrations of the subway deep underground... it was exhausting. She missed the silence of Kyoto. She missed Soseki, who was currently being babysitted by Panda, a thought that gave her mild anxiety.
She changed into the clothes. The fabric was high-quality. The skirt was structured, allowing for movement but looking sharp. The black turtleneck hid her pale throat and framed her face.
She stepped out.
Nobara was waiting, holding an iced coffee. She looked Miyuki up and down, then nodded once.
"Better," Nobara declared. "You look dangerous. Like a villain's secretary. I like it."
"Is 'villain's secretary' the aesthetic we are going for?" Miyuki asked, looking in the mirror. She had to admit, she looked... capable.
"It's better than 'victim'," Nobara said, taking a sip of coffee. She walked over and fixed Miyuki's collar. "Listen, Newbie. The clothes are armor. When you look like you can kill someone, people, and curses, hesitate. It buys you a second. And in our line of work, a second is the difference between living and dying."
Miyuki looked at the teenager. Nobara was young, but her eyes were old. She had seen death.
"You're wise for your age, Kugisaki-san," Miyuki said softly.
"Just Nobara," she corrected. "And it's not wisdom. It's survival. Now, hand over the card."
"The card?"
"Gojo's Black Card," Nobara held out her hand. "He gave it to you, didn't he? He said 'Buy whatever you want, put it on my tab'."
Miyuki blinked. He actually had given her a sleek, black metal card that morning, with a sticky note attached that said: Retail therapy is cheaper than therapy-therapy! Buy Nobara something nice, so she doesn't kill you. - G.
Miyuki handed over the card.
Nobara's eyes shone with a cursed energy of their own, pure greed. "We are going to bankrupt him."
