It takes the most reverent, breath-held sports anime KyoAni ever made and spends a whole episode on the boys cramming idol trivia for Masa-san's sake. That's the joke, and it lands because Tsurune normally treats a single release of the bowstring like a religious event. Kazemai and Kirisaki sharing screen time as collaborators instead of opponents is the real gift here, and it quietly pays off in how those clubs read each other later. Nobody's arc advances. Nothing is at stake. It's a gag reel with a bow rack in the background, and if you already love these kids you'll take it gladly. If you came for target panic and trembling forearms, know going in that this one is just the team being idiots for their coach.

Kazemai and Kirisaki are rival kyudo teams, yet they end up teaming up for an unusual reason: learning about a pop idol so they can help Masa. This single OVA episode never aired on television. It was shown early at an event and later came bundled with the fifth Blu-ray and DVD volume. Drama, slice of life and sports genres shape this side story about the two archery clubs.
