Choutarou Banba
The over-enthusiastic Osakan gangster-turned-good, Bancho was recruited into the team only because Ukiya believed Bancho 'has the eyes of a Gate Keeper'. With the mindset of a samurai, Bancho likens the girls in the Gate Keepers team as princesses and himself as their hero. It is only much, much later in the series that he reveals his latent Gate Keeper ability, the Gate of Solid Crush, which seemingly attracts Kaoru (perhaps because of the similarity of their gates). His Gate color is orange. (Source: Wikipedia)
