Riku Ishizuki

A third-year student at Hoshimiya high school, and a childhood friend of Takt and Shizuku. He has romantic feelings for Shizuku but suppresses them out of respect for her relationship with Takt. He often gets teased by shizuku, and has lewd dreams of her. Riku loves both his friends dearly and doesn't want to lose either of them hence the reason he bottles up his feelings. He seems to be quite popular among the ladies, the three main female characters already head over heals for him.
