Action

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.
    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 suicide.
    Hiroto was reborn once more as a half-Vampire, half-Dark Elf. A  Dhampir. Not wanting a fourth life, he is determined to live this third  life with the only things remaining from his previous  lives—death-attribute magic and his enormous Mana pool.
