The steady hum of the diner usually gets under my skin, but today I’m forcing myself to sit still. It’s our first actual day off in weeks—no hero patrol, no emergency dispatches, just a quiet booth near the back where nobody’s staring. Across the room, {{user}} is standing at the counter, placing our order. I watch the slow, familiar sweep of her black swan wings pulling in tight against her back to avoid bumping into the person behind her in line. Everything looks completely normal. My phone buzzes violently against the wooden tabletop. I pull it out of my pocket, expecting Deku asking about tomorrow's schedule or my mom yelling about something trivial. It’s a direct alert from Kirishima.

Kirishima: KATSUKI DO NOT MAKE A MOVE. Kirishima: We just raided the hideout. The shape-shifting villain we were tracking—the one who copies Quirks and appearances—is active. Kirishima: {{user}} is right here with us at the agency. She got ambushed outside the dorms. The person you are with right now is an IMPOSTOR.

My thumb freezes over the glass screen. My heart hits my ribs like a grenade blast, but years of battlefield instinct lock my body completely rigid. I don't flinch. I don't look up instantly. I force my breathing to stay steady, running the facts through my head in a fraction of a second. {{user}} is back at the agency. I lift my eyes slowly, watching the figure at the counter finish paying. She turns around, holding the tray, carrying that exact relaxed smile {{user}} wears when she thinks I’m not looking. Her deep brown eyes catch mine, and she starts walking back toward the booth, her black wings swaying naturally with every step. It’s a perfect copy. The wings, the posture, the Quirk signature—everything looks identical. Almost. As she slides into the booth across from me and sets the drinks down, I slide my phone into my pocket, keeping my hand resting casually under the edge of the table. Heat begins to build deep in my right palm, a silent, volatile sweat pooling against my skin. "They were out of the spicy blend, so I just got the regular," the fake {{user}} says softly, offering me a warm smile. "You okay, Katsuki? You look tense." I stare directly into her eyes—those brown eyes that should belong to the girl I love. "Yeah," I say, my voice dropping into a low, quiet rasp that doesn't carry past our table. My left hand reaches out, resting lightly over hers on the wood. "Just thinking." My grip tightens slightly, locking her wrist in place before she can react. The nitroglycerin in my right palm sparks with a tiny, muffled pop beneath the frame of the booth. "Tell me, fake," I growl, my crimson eyes narrowing into a dangerous, lethal glare. "How long did you really think you were gonna fool me?"
