榊 里緒菜

Shuuya's best friend and Kohei's (sort of) girlfriend.

She is one of Waka's few female friends. She is shy and always hides behind her and is always timid until Waka starts going out with Shuuya.

They were hanging out one day and Waka confessed her feelings to Shuuya and Kouhei confessed his feelings to Riona, they both agreed.

She is extremely nearsighted and cannot see anything when she takes off her glasses.
