Shūshi Mizuho is the original creator behind the manga Itsuka no Main: Kaminari Shōnen Tenta Sanjō, which was later adapted into an anime OVA. The manga, a seinen series blending action and comedy, was serialized in Shueisha's Weekly Young Jump magazine and ran for a total of eight volumes published between 1995 and 1996. Mizuho is credited with both the story and the art for this work.

The story centers on Kannonji Tenta, a middle school student and member of a bosozoku motorcycle gang in Asakusa who relies on bluffing rather than fighting skills. The anime adaptation, produced by the studio J.C. Staff, lists Shūshi Mizuho as the original creator.
