Reika is a large girl that is friends with Erika and is in the same class as Erika and Shou. She has a kind and quiet personality. Despite being large, she has an affinity for soccer. When the team needs one more player to qualify for the preliminaries, Reika steps up. Originally she states that she wants to play soccer for dieting, which really angered the Furuyas (especially Kota). She finds that she loves soccer and pushes hard to prove herself to the team, particularly Kota. It is shown that she is in a well-to-do family and that she is secretly skipping her piano lessons to practice soccer under her mother's nose. She is a hard worker and is seen early in the morning practicing hard so that she won't be a burden for the team
