Hoozuki no Reitetsu

The afterlife includes Heaven and Hell, with Hell divided into the Eight Greater Hells, the Eight Cold Hells, and 272 additional subdivisions. Managing the vast and complex operations of this enormous Hell is a single Fierce God, Hozuki, who serves as King Enma's top assistant. Hozuki and his diverse group of colleagues handle the endless and varied tasks of Hell, often resulting in chaotic and lively situations. Despite the book's portrayal of Hell as an eventful place, it encourages readers to behave well in life.
