Description
Iroha Mizuno is a 12-year-old character from the anime Cap Kakumei Bottleman DX. He is a close friend of the main protagonist, Cota Coga, having known him since early childhood. Iroha was initially introduced to Bottle Battles through the influence of another character, Mitsuya, which sparked his interest in the competitive activity where he participates as a normal-ranked battler.

Physically, Iroha is characterized by his reddish-brown eyes and brown hair that features distinctive light green tints or streaks. His most consistent visual trait is his round glasses, which he wears at all times and which are said to aid his concentration. His typical outfit consists of a green tracksuit accented with orange, blue, and white details, light blue shorts, white socks with orange and light green stripes, and light green and blue shoes.

In terms of personality, Iroha presents as quiet and modest, often serving as the more intelligent and practical member among Cota's group of friends. He demonstrates a strong determination when pursuing his goals, though he sometimes requires encouragement or a push from those around him to fully commit. When he becomes excited or has confidence in his own victory, a more self-assured and confident side of his personality emerges. He has a noted love for data analysis and can often be found reacting to or providing commentary on situations around him.

Iroha's journey in the story involves significant growth and changing allegiances. He initially uses an unnamed Bottleman with white, beige, and lime green coloring but undergoes strenuous solo training to improve his skills. His dedication pays off when he acquires Valhas DX, a multi-type Bottleman, which becomes his primary partner starting from Episode 41. A major narrative arc involves Iroha joining Team Citrus alongside Mitsuya and another character named Santa, with the goal of supporting the idol Citrus. However, he and Mitsuya eventually leave the team due to disagreements with Citrus's new ideals. Upon discovering that Citrus was being unwillingly controlled by an artificial intelligence, Iroha aligns himself with Cota and the supporters of the BMA to oppose Team Citrus. Later, he participates in the Bottle Royale tournament meant to decide the Bottle King, though he is eliminated early in the competition by Cota. Following the resolution of the AI crisis, Iroha is seen supporting Cota and Ryo alongside his other friends and rivals.
