Seki, Kazuaki
Summary
Kazuaki Seki joins the Eisen swim team after the coach unexpectedly tests him while he was on his way to watch Ami dive. He passes the evaluation even though the exam was deliberately set to be more difficult than usual. Keisuke helps him overcome a personal slump by making him tutor the coach in swimming, a process that forces Seki to concentrate on refining his technique. Additionally, he holds a 3rd Dan rank in karate.
