七瀬遙

Haruka is a second-year boy in high school who loves swimming and being in the water. He is a strong and quiet person who displays limited facial expressions, and has a hard time communicating his feelings.

His style captivates many and he has a strong fixation towards freestyle swimming. His love for water is so strong that he often strips down to his swimsuit at the sight of water and even considers encountering a waterfall to be a romantic experience.
