I've seen it. I have seen it several times. It's called a blade tooth. There are two movies, and the cartoons have not been released yet. Someone translated them at the blade tooth bar. Van Mabaki, Van MayoJiro, let's bet no, that's it. His father's back muscles are called ghost back muscles. His father fought in the war before, and killing people is terrible. His back muscles also said that it was not an accidental natural phenomenon, but death or demon possession. Blade tooth, that's it. Dad's name is Fan Mayong Jiro. His brother's name is Van Marjak, and the protagonist's name is Van Marbage. His father is called the strongest creature on earth, isn't he?
