this girl is ichika matsumoto. she is my childhood friend. ichika's grandfather was called "masaru matsumoto" and was a legendary shogi player in the shogi world. ichika, who was her grandfather's favorite, inherited the strategy "bougin" that her late grandfather excelled at, but this is extremely strong and i have never been able to win against ichika. i like her as a friend, rival, and as the opposite sex. i decided to confess my feelings when i finally won against ichika.
