Shin Megami Tensei [Kahn]

Six months ago, Karukozaka High School mysteriously vanished without a trace. When it reappeared, every single person inside—students and faculty alike—had disappeared. The incident was quickly dismissed as an unsolvable mystery and faded from public memory, though few realized that two students had somehow returned. Nobu, a boy with an unusual talent for sensing demonic presence, and Yumi Shirakawa, a fellow survivor, attempt to rebuild their lives by transferring to separate schools and cutting ties with their traumatic past. However, they soon discover that the supernatural forces they encountered haven't finished with them yet. As strange occurrences begin to manifest around the former site of Karukozaka High, two powerful organizations take notice of the returned survivors. Each group has their own vision for humanity's future and their own plans for how Nobu and Yumi fit into it. With the boundary between worlds growing thinner, the two students must decide whether to continue running from their past or face the darkness that threatens to consume their world.
