Seiji Chuutamari

Seiji Chuutamari is a very minor character who was one of the participants of the under 16 Kakinokizaka Junior Tennis Tournament held in Kakinokizaka Tennis Garden in the first episode. He is never shown in the series. He is placed at 49th position on the match sequence board just below Ryoma and may have been his second opponent in the tournament if he had won in the first match. But Ryoma does not make it in time due to Sakuno misleading him at the station, and so the match between them never happened.
