HELMUT

Helmut was only a baby when he was left in the Forest of Pahe, an evil place full of beasts where sinners are banished for eternity. Luckily, one magical beast and an exiled swordsman take pity on him and raise him as their own. But with a dark seed growing inside him, Helmut decides to take up the sword to prevent the seed from turning him evil. As Helmut grows stronger, he seeks out the family that abandoned him, but will Helmut end up following his human heart or his beastly instincts?(Source: Tapas) — Description from AniList community (anilist.co).
