Hoozuki no Reitetsu

In the afterlife, there exists Heaven and Hell. Hell consists of the Eight Greater Hells and the Eight Cold Hells, which are further divided into 272 subdivisions. Spearheading the seemingly endless, multifarious affairs in this gargantuan Hell is but one Fierce God, King Enma's first aide, Hozuki. Between this cool-headed sadist and his colorful band of peers, every day is a riot in Hell! And though this book might make Hell seem like a happening place, please try to behave during life!
