Bunkazanai is basically soem sorta ghost-and-demon story that you wouldn't want to be stuck in.
A girl, Suka Himarei, goes to school one day, but his school isn't her school, which she realizes once she gets is. She tries to leave, but the door's locked behind her. She's trapped. She then is ordered to live there by Naiyotogi(Dead-watcher), a head man there. She gets thrown in a room filled with boys her age-sleeping in brown sheets. She gets to meet street-smart Tohru, and softer,girly-looking-haired Yukii. she learns that the school was destroyed years ago and abandoned, and 'chosen ones' think its their real school, and when they get in, they realize it, but it's too late. The school's classrooms have ghosts-good and evil-lurking in them, and some of the kids are ghosts themselves.
A part I though of:
Suka sees Yukii murdered by Naiyotogi, and his spirit's still there, and they were going to take him away, but she then threatens them, and goes into the Science room, a very haunted room, since they don't believe her threats.(Girls are sacred to the school, since barely any ever come)She then meets Prof.Watanabe, who then turns into a demon ghost. She almost gets killed-until Yukii rescues her. The men working for Naiyotogi leave her and Yukii alone-and his spirit is owned by the school, so he can never go to Heaven. He likes his fate,since he'd ratehr be with Suka and Tohru.
Yeh, I dreamt this all last night. O.o
