Endure It, Chokkaku! A Promise to Father

After the tournament, Chokkaku and Gō become fast friends. But word of their daily brawls reaches Chokkaku's father. Angry and grieved, Kotayū declares that if Chokkaku ever draws his wooden sword in a fight again, he will be made to commit seppuku. Meanwhile, Tsukigata and his gang lord it over the academy, using brute force to do as they please. Unable to stand their tyranny, Gō urges Chokkaku to teach them a lesson — but Chokkaku has a promise to keep.
