Rebirth in a new world can bring unexpected surprises. For example, you, until recently a thirty-year-old man, may find yourself in the body of a newborn baby, and even a female one. And the blood of a demon flows in your veins, because of which those around you from an early age fear and despise you. Well, the cherry on the cake: instead of becoming a great magician or master swordsman, you end up training in a strange dojo where they practice hand-to-hand combat. Hand-to-hand, damn it, combat! In a world inhabited by demons and other evil spirits! And what do you want to do with such a second chance?
