Gatekeepers

The four Gate Guardians each defend one of the four gates of the Seireitei. Jidanbō Ikkanzaka, a giant from Rukongai, defends the west-facing White Road Gate.

The other three gate guardians are only briefly seen, having betrayed Soul Society and become agents of Aizen, who had hypnotized them. They are: Hikonyūtō, guardian of the Red Hollow Gate; Danzōmaru, guardian of the Black Ridge Gate; and Kaiwan, guardian of the Blue Stream Gate. The three are easily defeated by Jidanbō and Kūkaku Shiba.



Trivia

 * Jidanbō had said that the other Gatekeepers were on very good terms with each other. Because of this, their nonchalant attitudes towards one of them falling is thought to be so due to the effect of Aizen's Zanpakutō.
