Amamiya Hiroto is unlucky. His life consisted of misfortune after misfortune, culminating in an unlucky death during an incident on a school boat trip, trying to save a girl he barely knew. After death, he met a god of reincarnation who requested that the hundred or so dead passengers—one of them being the girl he tried in vain to save—be reincarnated into another world.... more>>

Yet a series of unfortunate events forced Hiroto to reincarnate with even less luck than before, starting with nothing but a tremendous amount of Mana. His second life, far worse than his first, came to a cruel end.

However, upon meeting the god a second time, he was informed that there would be yet another reincarnation—one that had already been set in motion and could not be stopped. Not wanting Hiroto to live long, the god cursed him before he was reborn in the hopes that he would either die quickly or commit su*cide.
