Owarimonogatari

Ougi Oshino, an unusual new transfer student at Naoetsu Private High School, is introduced to senior Koyomi Araragi through their mutual friend Suruga Kanbaru. Ougi seeks Araragi’s insight after noticing something unsettling in the school’s layout: a classroom sitting in a section that should be empty, as if it were never meant to exist.

With the possibility of an apparition in mind, Araragi and Ougi investigate the anomaly together. When Araragi ends up trapped inside the room with Ougi, the mystery takes on a more personal edge, drawing out the lingering trace of an incident he’s forgotten for far too long.
