The Draft of Citrus

During a friendly kendo match, Ritsuryokan High School, a regular at the Inter-High School Tournament, was having a hard time with Tsubakigaoka Academy, which just became a co-ed school this year. The reason for this is Kunihiko Yanagida, the vice-captain of the Tsubakigaoka team, who came in 8th at last year's Kanto Junior High Tournament. Furthermore, Tsubakigaoka still had a secret weapon in reserve. The name of the captain was left blank on the match-up list. Who will fill this position...? (Source: Shogakukan, translated)
