Yoshitsune Tesshū

Yoshitsune Tesshū (鉄舟山岡) is a member of the Tesshū family and daughter of Yamaoka Tesshū, the heir the family throne attending Masahige High School.

Yoshitsune has apparently had a crush on Orion Masahige even before he left because they spent a lot of time together.

However, ever since Orion has become a spawn of the family and then quit the second family he was in, Mugendai, her mother has banned Orion from the compound. Orion called her Yoshi (ヨッシー, Yosshī) when they were younger, apparently. She has coined the nickname as it seems everyone close to her calls her this.
