Ruri Ginjō

Ruri Ginjō is an active female junior high school owner who is only 15 years old, but struggles to make Silver Castle lively. After being informed that Ricardo, the former owner of Silver Castle and her father had died, she inherited Silver Castle and became the owner of the team and manages it.

Her carefree and bright smile is a big attraction, and she has always encouraged the players to play fair and is there for them. Since she keeps her father's belief that one should play fair and square, she is surprisingly solid in the part that she never allows rough play even if she and team loses. Yet even though the team is like a family to her, the loneliness of losing her father cannot be easily wiped out.
