4 Cut Hero

Story:

The Hero has defeated the Demon King, but the Princess he intended to save has been revealed to be a Prince. NEETdom awaits, but a life of relaxation surrounded by anime is a fairly good offer. Unfortunately, he becomes entangled in millennia-old legends, curses, and a convoluted scheme involving various Kingdoms and numerous dragons. Through and through, he'll follow a road of whimsy, even if it means palling it up with "villains."
