Kazusa Yuu, a Japanese high school student interested in food and camping, dies in a traffic accident and ends up reincarnated in the wilderness in another world. He must learn to survive in an unfamiliar environment, learn the powers he was granted and the magic of the world that is based on eating other creatures, and rescue fair maidens in distress to feed them and build up his harem.

This is the story of a "princess" who torments the whole world. She is loved by God, she has beautiful hair, and she wields a violent blade. She was the prettiest young lady in the kingdom, but she was also the most powerful of mercenaries, nicknamed "Savage Fang." All of them are now beginning to be trampled by a girl who defies expectations.

"It has been too long since I reached the so-called peak of magic art" "I get my answers before even doing anything... And such a life is boring" "So i got an apprentice for myself." The manga is from the perspective of Arietta (Arietta Pelcia) the apprentice, bought form slavery by an incredible, yet bored magician (Theo Elvram).
