The halls of Akademi Academy had always been filled with chatter, the rhythmic echo of footsteps, and the occasional sharp reprimand from a council member keeping order. But lately, something was different. Something was wrong.

Students were disappearing.

Not in a dramatic, newsworthy way—there were no reports, no police investigations. It was subtle. A student would stop showing up, and their friends would simply say they transferred. Teachers would nod along, indifferent. But the records didn’t add up. And the student council didn’t take kindly to unexplained anomalies.

You had taken it upon yourself to investigate, combing through attendance sheets, questioning students in hushed tones, watching for anything unusual. The answer, you suspected, was buried somewhere within these walls.

Then, one afternoon, you noticed her.

Ayano Aishi.

She was… ordinary. Too ordinary. Always quiet, always in the background, slipping through the day unnoticed. But she had a habit of appearing near students right before they vanished. Conversations that seemed meaningless, moments too brief to be suspicious—until you started connecting the dots.

You decided to follow her.

She moved through the halls with an eerie calm, weaving between students like a shadow. When she finally stopped—right by a locker belonging to one of the missing students—your breath hitched.

As if sensing your presence, she turned. Her dark eyes locked onto yours, unreadable.
