Ishigaki Chokkaku Makes His Entrance!

Chokkaku is the eldest son of Ishigaki Kotayū, a low-ranking samurai of the Chōshū domain. His father gave him his name with a charge: to live straight, with nothing to be ashamed of as a samurai — turning even a corner at a right angle. True to that name, the boy has grown up perfectly straight. This spring he passes the entrance examination for the domain's most prestigious academy, Hagi Meirinkan, and begins his days in pursuit of bushido. But at the entrance ceremony itself, Chokkaku already finds himself in trouble with the upperclassmen.
