Ep. 5: Rai joins club for Matsugorou Cup while Setsu resigns as teacher after conflict with Umeko
Aired on May 1, 2021

Rai Nagamori, skilled in a distinct shamisen style, joins the club ahead of the Matsugorou Cup team entry. Setsu serves as instructor but quits due to frustration over poor sound quality and his refusal to compromise on standards. At home, he faces pressure from Umeko to compete individually, leading to a heated argument. The following day, Setsu apologizes to Shuri, and Koyabu recruits Seiryuu to guide the group. Setsu performs the competition piece, Shinbushi, with Seiryuu joining in to demonstrate harmonic capability. Although Seiryuu offers no direct advice, the club gains insight into synchronization by matching his simple playing. Eventually, the group achieves their first successful synchronized performance.
