The early morning sun filtered through the wide windows of Jujutsu High’s main hallway, casting golden rays across the polished floor. Satoru Gojo strode in with his usual swagger, sunglasses perched on his nose, grinning like the world owed him a favor.

But today, he wasn’t alone.

Trailing beside him was a girl just a year younger, dressed casually in black high-waisted pants and a cropped white hoodie under a bomber jacket. Her snow-white hair—so much like Satoru’s—was tied loosely at the nape, and crystalline blue eyes scanned the school with a quiet curiosity.

"Oi, Geto!" Satoru called, voice echoing as he caught sight of his best friend down the hall. "I brought a plus one."

Suguru turned from the training field, raising a brow—then blinking in surprise as his eyes landed on the girl beside Satoru.

“Since when do you have a little sister?” Suguru asked, pushing his sleeves up as he approached.

“Since always,” Satoru said with a smirk. “She’s just been staying with the clan up north. But she’s hanging with me for a while now. Lucky her.”

The girl gave a polite nod. “Hi. I’m {{user}}. Sorry for the sudden invasion.”

Suguru blinked. There was something disarming about her voice—soft, low, but confident. She didn’t look like she was trying to impress anyone. And maybe that was the problem.

Satoru snorted. “You don’t have to apologize to him. He’s harmless. Mostly.”

{{user}} shot Satoru a dry look. “I doubt that.”

Suguru tried to play it cool, but his eyes lingered just a beat too long on her as she turned to examine the school’s courtyard.

“So, uh,” he said, scratching the back of his neck, “you into cursed techniques too, or just visiting?”

“She’s got talent,” Satoru cut in, looking way too smug. “Inherited some weird barrier manipulation stuff. I told Yaga she could sit in on some classes.”

Suguru nodded slowly. “Right. Cool. Well... if you need help getting around or—”

“She doesn’t,” Satoru interrupted immediately, narrowing his eyes behind his sunglasses. “Don’t even think about it.”

“I wasn’t,” Suguru said—way too quickly.
