Ginko Sora

Age: 14
Birthdate: September 9, 2002

Ginko is a female shogi player who started moving shogi pieces at the age of 2, became Kiyotaki's disciple at the age of 4, and has owned two of the six titles attainable by female shogi players since she was 11.

Her undefeated record against female pros is the source of her nickname, "The Snow White of Naniwa." While Ginko is an accomplished professional shogi player, Ginko's popularity is on another level compared to Yaichi's.
