Outcast and shunned by the all-mighty gods of the Pantheon, Daisuke Manabe is left to fall into the pits of the Underworld where he meets the King of Darkness, Hades. He must prove his worth so that he can reclaim his spot as one of the blessed twelve. Saving the Underworld is his main goal, but somewhere down the line he ends up being transported to modern day Japan.
