A 5000-year-old vegan dragon was living peacefully when one day a young girl showed up in his cave. She offered herself as a sacrifice in order to gain favor for her village. He played along as the great "Evil Dragon, the Demon Lord's Army Leader" in order to get rid of her. However, his little white lie awoke her hidden powers and his peaceful life suddenly ended.

The Hero has defeated the Demon King, but the Princess he meant to save turned out to be a Prince. NEETdom, here he comes, but a life of relaxation surrounded by anime is a pretty sweet deal. Unfortunately, he gets caught up in millennia old legends, curses, and a twisted plot involving multiple Kingdoms and many dragons. Through and through, though, he'll follow a path of whimsy, even if that involves him palling it up with "villains".
