This is a story in which an aloof (?) Young evil dragon who is "lonely, cold, not understood by the world and does not conform to the world" brings up a big sister and a goddess who is "my destiny is determined by nature. I can't help but have an opinion, even if I say I'll beat you, it's okay to hit you", and finally upgrades and transforms and is adopted by the goddess as a little brother-in-law. This is a story about a profiteer wizard who "makes money through entertainment and gossip" and the middle-class tsundere dragon he raised (trying to pretend that he destroyed the world) to help the soy sauce god. Also known as, "Sister, can you not cheat your teammates?" ?
