Welcome to Dead Rock, the underworld's top educational institution! A spot at this training facility for demonic mischief is all the young demon Yakuto has ever wanted, but in Hell, there's no such thing as an easy A. Plenty of Yakuto's fellow prospects won't survive the entrance exam, and even fewer will make it to graduation. So why bother? The prize, for those who survive this death game through perdition, is the world, in the palm of their hand!
