Choutarou Banba  

Banchou, Big Boss, 番場 長太郎

Bancho was an Osakan gangster who became a member of the team due to Ukiya's belief that he had the eyes of a Gate Keeper. He viewed the girls in the Gate Keepers team as princesses and himself as their hero, with a samurai mindset. It wasn't until much later in the series that Bancho revealed his latent Gate Keeper ability, which attracted Kaoru due to similarities between their gates. His gate color was orange.
