Teppei

Teppei (鉄平, Teppei) is a famous Saiseiya under the tutelage of Yosaku and is the grandchild of "Knocking Master" Jiro, from whom he inherits the title. He decided to become a Saiseiya after seeing a once beautiful valley that his grandfather used to hunt in, be turned into a barren wasteland due to over-hunting.
