Description
Mizuno Iroha appears in two iterations of the "Cap Revolution Bottleman" franchise. In the web series, he stands among Cota Coga's friends and operates an unnamed Bottleman with white, yellow, and green coloring.

The television series "Cap Revolution Bottleman DX" offers a fuller depiction. Iroha, aged 12, maintains a quiet and modest demeanor, consistently wearing glasses to aid concentration. His physical traits include reddish brown eyes and brown hair featuring light green tints. He typically dons a green tracksuit with orange, blue, and white accents, light blue shorts, white socks bearing orange and light green stripes, and light green and blue shoes.

Beyond his reserved nature, Iroha demonstrates intelligence and practicality within Cota's friend group. Though determined in pursuing goals, he often requires external encouragement. A confident side surfaces during excitement or when victory seems assured. He shares a close childhood bond with Cota Coga and developed an interest in Bottle Battles through Mitsuya's influence, competing as a normal-ranked participant.

Initially using an unnamed Bottleman with white, beige, and lime green coloring, Iroha trained diligently to acquire the multi-type Valhas DX as his partner in Episode 41.

His narrative arc involves joining Team Citrus alongside Mitsuya and Santa to support the idol Citrus. He and Mitsuya later departed due to disagreements with Citrus' new ideals, discovering Citrus was unwillingly controlled by AI. Aligning with Cota and BMA supporters, Iroha opposed Team Citrus. He competed in the Bottle King deciding Bottle Royale but was eliminated early by Cota. After resolving the AI crisis, he appeared supporting Cota and Ryo among friends and rivals.

The web series iteration lacks the DX series' extensive background, relationships, and development.
