Shintarou Kisaragi, a technology enthusiast, had secluded himself in his room for two years until an argument with Ene, a computer resident, led to a cola spill that damaged his keyboard. Needing a replacement, they discovered the store closures during Obon festival, forcing them to leave their place of comfort and visit the nearby department store. Ironically, Shintarou found himself involved in a frightening hostage situation on the same day. Fortunately, the "Mekakushi Dan," a group of teens with inexplicable sight abilities, saved him and added him and Ene to their team. As their pasts unfold, the puzzle pieces of their connection slowly fit together.
