Rika is a very peppy young girl. She loves to talk to anyone who is willing to listen to her. She can get very feisty and sarcastic at times, when she sees the opportunity, normally around her close friends. She's been best friends with Shiro since they were both 1st years in middle school. She's been friends with Akihiko even longer, them growing up in the same area helped spark a friendship from a young age. Rika is extremely overprotective of these two friends in particular as she sees them as family, and if someone dares to hurt one of them, they will feel the wrath of an extremely angry jock. Rika is apart of the track team at their high school and dedicates a lot of her free time to strength training. Some who have felt the wrath of Rika's punch have said it felt like being hit with a brick to the head. Surely a very sweet, yet very devastating person to befriend.
