Intro
You were on patrol in the forest late at night when, without warning, a portal tore open in front of you. Its pull was relentless, dragging you—and several demons—through before you had the chance to resist. When you came to, you realized you were no longer in your world. Everything felt foreign. For days and nights, you’ve tracked down the scattered demons that were dragged through the portal alongside you. So far, you’ve slain twenty, but you know forty still remain. The hunt never ends.
Tonight, while patrolling near a strange building labeled “U.A. Class 1-A Dorms,” you catch sight of a demon slipping through the gates. You’ve seen students living on this campus before, which means there’s no time to waste.
You vault over the wall, blade drawn, and intercept the demon before it can get any farther. Steel clashes against razor-sharp claws as the two of you exchange a relentless barrage of attacks beneath the moonlight.
The commotion doesn’t go unnoticed.
Lights flick on inside the dormitory.
The front door swings open.
Bakugo: lOI! WHAT THE HELL’S GOING ON?!”
Midoriya: “Wait… that’s not a Nomu.” His eyes dart rapidly between your blade and the creature. “I’ve never seen anything like it…”
Kirishima: “Who’s the girl?! She’s fighting that thing by herself!”
Yaoyorozu: “Aizawa-sensei should be notified immediately. We don’t know what either of them is.”
Todoroki: “Stay back.” His gaze remains fixed on the battle. “Until we know what’s happening, assume they’re both potential threats.”
@: Mina: “Whoa… she’s actually holding her own!”
You spare the group a single glance. A handful of students stand outside in their pajamas, staring at the battle unfolding before them with varying expressions of shock, caution, and curiosity.
You don’t have time to explain.
The demon lunges again.
You pivot on instinct, narrowly avoiding its claws before driving your Nichirin blade toward its neck. The creature screeches, forcing itself backward and, in its desperation, charges straight toward the students.
A sudden burst of grey fabric flashes across the courtyard.
Aizawa lands between the demon and his students, his capture weapon already unfurling around him. “Class 1-A.” His voice is calm, but firm. “Inside. Now.”
No one moves.
Bakugo clicks his tongue, already igniting small explosions in his palms.
Bakugo: “Like hell I’m—”
Aizawa: “That’s an order.”
Bakugo scowls but doesn’t advance, while the rest of the class reluctantly begins backing toward the dorm entrance, their eyes never leaving the battle.
Aizawa’s sharp gaze shifts from the monstrous creature… to you.
An unfamiliar swordswoman. Unknown attire. Unknown weapon. Unknown enemy. His eyes narrow. “Who are you?”
