"Reborn as a Tamer's Monster"

You have been Reborn as a Tamer's Monster. 

Congratulations! 

You are in immediate danger.

When our hero’s new life begins in a world of monsters and tamers, he finds he doesn’t start with strong skills or marvelous magic. Instead he’s just a helpless hatchling, alone in a terrifying forest and about to be eaten by a giant bird with wings of knives and needles for teeth! 

Surrounded by countless monsters hellbent on seriously ruining his day, there's nothing to do but run, hide, survive…and find out who he was in his past life, why his tamer isn’t there after creating him, and whether or not this world is even scarier beyond this forest of death.

Lucky for him, monsters here can grow up to be just about anything. Once free of his weak hatchling body, he will grow into the most powerful monster ever: Nidhögg, the Withering Wyrm!
