汐宮 志保

A former competitive swimmer who was the idol of Taito, but she has since retired and settled down. However, since she still has a lingering affection towards swimming, she has taken a part time job as an instructor at a swimming school. Due to her competitive nature, she is strict with herself and everyone else she teaches. She's not good with kids, so the children at the school are afraid of her. [Translated from Getchu]
