About

Something is wrong with this apartment building. The place the protagonist moved into was a perfectly ordinary apartment complex found anywhere. ...Except for one single, strange thing. The elevator only goes up to the 12th floor. And yet— When midnight strikes, a button for **"Floor 13"** appears, even though it shouldn't exist. A button that glows a deep red. Driven by curiosity, the protagonist presses it and arrives at the unfamiliar 13th floor. There, rows of rooms with lights turned on await, even though no one is supposed to live there.
