Onigawara isn't really wanting to learn about being dead...he wants to collect on the deal he made with teacher Mitamura. Complete the set task within seven days and he gets his life back. The clock is ticking but there is one thing Onigawara is as yet unaware of. Once you're dead, you stay that way. The task given just seems to get harder and harder, though. Things just keep spinning out of control. Only its not just Onigawara who seems to be in trouble when it does...
