Hayato Arakawa was a droppout disaster whose existence was brought to a close through the means of a pizza box, a puddle of soda, and one really, really bad extension cord.

Reborn as a non-magical royal baby, he's branded a curse and discarded into the demon worlds before he can even crawl.

Years pass, and whispers circulate among kingdoms of a mysterious figure who commands monsters, overthrows kings, and appears whenever there is strife afoot.
They call him a demon king, a god, a myth.

The reality?
Hayato just wants a quiet life, a full stomach, and enough money to live freely in this crazy new world.
