Y/N L/N has reclaimed his body, but the world he returns to is no longer the one he left behind. Otto Octavius, the self-proclaimed Superior Spider-Man, left behind a legacy of innovation, broken trust, and unfinished battles. But what happens when Y/N is left to die after a fight against the mutated Green Goblin? He's then resurrected as a devil by Rias Gremory, a beautiful devil who was a student at his school. Y/N becomes her servant and gets involved in the supernatural world of angels, devils, and fallen angels, fighting alongside Rias and her Occult Research Club as he tries to regain his wings to ascend to Heaven.
