The Idaten Deities Know Only Peace (Volume 1)

It's been eight hundred years since the powerful Idaten deities sealed away the demons who plagued humanity. To the foul-mouthed Hayato, a young deity, the story is mostly a myth. There's just not much to do as he and his generation watch over humans in peace. But when the seal on the demons breaks, it's up to Hayato and his oddball compatriots to come to humanity's rescue! Can these misfit gods who know nothing of war rise to the challenge?
