古手 梨花

Rika is a grade lower than Keiichi, and thus is a classmate of Satoko's.

She is very quiet and reserved for her age, which makes her almost the polar opposite of Satoko. However, the two of them can often be found in each other's company.

Whenever Satoko is in tears after losing against Keiichi, it is Rika who cheers her up. When Satoko wins, Rika comforts Keiichi instead. When Keiichi teases Rena, Rika comforts her.

In fact, Rika comforts whomever is in need of comfort.

She seems happy with it.
