Meguru Watase 渡瀬めぐる

Meguru is a close friend of both Misaki and Yuu. In middle school, she is a national champion in swimming, making her a reserve candidate for the Olympics. However, Meguru quits swimming when she enters high school because her breasts grow too large and attract too much attention when she's in her swimsuit. Unfortunately, those who are attracted don't include Takei, whom Meguru secretly likes.
