There is a curse in the protagonist's family, which causes random reproduction and spread of blood. So the protagonist found a woman dressed as a woman to curse and suppress it. I thought they would balance each other out, but they ended up coming together. The protagonist is sweet-mouthed and ruthless. Although he acts like a good boy on the surface, he must be doing evil things secretly! I like to pretend to be weak, green tea, and give the opponent a mental critical hit when he puts down his guard! Anyway, it's a bad thing.
