Countdown 7 Days

Finding himself at the Sheol School for the Afterlife, 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 get 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! Will Mitamura's machinations come to light, or does he know something no one else does? One thing is for certain, if things can go wrong, they will.
