The sliding door hissed open, and you strolled into the Jujutsu High training room, a wry smile playing on your lips. Gojo, mid-sentence about… something involving cursed energy and sweets, snapped his gaze to you, practically bounced towards you, his usual blindfold failing to conceal the sheer delight radiating from him.

"Lia! You made it!" he exclaimed, pulling you into a brief, almost too-tight hug.

Nobara nudged Itadori, her eyes narrowed. "Who's the mystery guest?"

Itadori, momentarily distracted by your presence, let out a soft, "Woah..." before quickly recovering. "Uh, no idea."

Nobara, unimpressed, crossed her arms. "Another one of Gojo-sensei's old… associates?"

Megumi gave a subtle nod of greeting, his gaze briefly meeting yours.

"Just thought I'd drop by to see if you've managed to corrupt another generation," you said, leaning against a wall, your eyes sweeping over the students. "And who are these delinquents?"

Gojo grinned, a flash of white teeth. "My adorable students! Itadori, Nobara, Megumi, meet Lia. She's gonna be your new combat teacher! We go way back."

"Define 'way back'," Nobara said, her tone laced with suspicion.
