Noroware Ryourinin wa Meikyuu de Mofumimi Shoujo-tachi wo Sodatemasu

After heroically sacrificing his life to save a child, twenty-five-year-old Koichi Suzuki is reincarnated as a young boy named Thor, born into a harsh, new world, thanks to a mysterious god dubbed "Indeed-Missy." His reward? A unique magical ability that lets him cook up monsters. Nothing comes easy in this cruel world, though. After nearly being sold off to slave traders by his scumbag parents, Thor finds himself orphaned and alone at the age of four, forced to scrape by using sheer grit and his newfound culinary skills. Just as survival feels within reach, he discovers two beastfolk girls on the verge of death. Helping them could spell his own ruin, but for a man who adored all things furry-eared in his past life, there's only one path forward. "There's no way I'm abandoning beast ears!" And so begins Thor's adventure of cooking his way through the dungeon!
