The Proxy of Yama

Don't think that mediocre men have no spring time. A little gangster that takes protection fees in front of the school entrance strangely became the highest administrator of hell. Now, things are getting interesting. Being King Yama, fighting the heavens, reforming hell's system, and leading ghosts to resist the oppression by the gods of heaven… Finally, I'm at the highest position within the heavens and hell. Mwahaha…
