Literally what the tag says, UNPRINCIPLED, the author is literally trying to make u hate the MC, he has ok interaction with his sister and the female classmate, however anyone else or anything else, he sees as weak or not worth it, he himself acknowledges that divine beasts are very rare, however when he sees other ppl with beasts less than saint rank he disdains them unnecessarily. Good story trope ruined by the character himself. He is intelligent don't get me wrong, but he behaves over-smart.
