From LHtranslation :

In a certain world, there was someone who excelled in magic combat, people called him 『Sage』. Seeking the strongest combat art, he devoted himself to research every magic and combat arts in existence. And the conclusion he arrived at was very cruel, 『My body is not fit for magic combat』. Yet he didn’t give up. He sealed his own soul with a magic art, and was reborn in a far-off future. And the magic theory in the completely changed world he saw there was of unbelievably low level.

At that moment, he heard the sudden sound of a voice inside his head. ≪ The monster has been subjugated, gaining experience points. ≫ 「Eh?」 Before anyone knew, the world has changed. Monsters appear, this is a game-like world where levels, skills, and status exist. This is an adventure where the modern world becomes fantasy and where the main protagonist has to strive hard for his survival.

Fujiwara Naeka is a typical 17-year-old high school student. Or so we thought.

“Why did I possess this character?”

Flash was the only magic skill I was given.

The world is ending. Monsters from legends appear everywhere. They eat people, conquer the streets, and begin to make dungeons in the buildings and subways.

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 endure a third life filled with suffering, 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 Magic and his enormous Mana pool.
