The rumors had been circulating through the hero society for weeks now—whispers about strange doppelgängers appearing in the streets of Musutafu. Witnesses claimed these shadowy doubles weren't quirks in the usual sense, but something stranger: reflections born from the collective thoughts and perceptions of everyone around a person. No one knew the exact cause—maybe it was some unknown quirk manifestation? A psychological phenomenon amplified by the intense emotions of pressure? Or something deeper tied to the shared unconscious fears and impressions of the person?

What was clear was the pattern: the doppelgänger mirrored the original's abilities and memories perfectly, but its personality twisted into whatever the majority believed or feared the person to be. An innocent person seen as ruthless by rumor would spawn a cruel echo; a calm one labeled unstable might birth a chaotic mirror-self. The figures appeared fleetingly at first, reacting to attacks in eerie, impossible ways before fading, leaving everyone questioning what was real.

Today in the U.A. training grounds, the air hung heavy with tension. You and Class 1-A formed a loose circle around the wide practice arena, training dummies forgotten as eyes darted nervously. Sweat still clung to your skin from earlier drills—your movements always fluid, shifting seamlessly between defense and offense, never locked into one rigid style or mindset. That adaptability kept you balanced, ready to flow with whatever came next, whether it was a sudden shift in mood, strategy, or threat.

Then the air near the far wall shimmered like heat rising from pavement. A figure stepped out—your exact double in appearance, stance, even the subtle way your quirk hummed beneath the surface. But the aura was all wrong: distorted, amplified by the swirling mix of awe, wariness, and unspoken assumptions from your classmates. It mirrored your combat prowess perfectly, memories intact, yet something darker edged its expression, shaped by whatever fragmented ideas the others held of you in that moment.

The doppelgänger locked eyes with you, a cold smirk curling its lips that didn't quite match your usual calm readiness. Without warning, it closed the distance in a blur, launching a strike that copied your own signature combo—precise, adaptable, but laced with brutal intent. You barely dodged, feeling the displaced air whistle past your cheek.

Classmates gasped and scattered into defensive positions—Bakugo snarled curses, Midoriya's eyes widened in analysis mode, Uraraka floated slightly off the ground ready to intervene. Kirishima hardened instinctively, shouting, "What the hell is that thing?!"

From the edge of the arena, Aizawa's voice cut through sharp and low, his capture weapon already uncoiling slightly in precaution.

"{{user}}, focus. That's not you—it's feeding off what everyone thinks you are. Don't let it dictate the fight, and shut it down before it escalates. Everyone else—hold position unless it turns on you. We don't know how far this thing can spread."

The doppelgänger didn't pause, twisting mid-air to evade an instinctive counter if you threw one, its movements eerily familiar yet laced with that unnatural edge. It was waiting—daring you to meet it head-on, to see just how far the collective perception could warp what should have been only yours.

Your move.
