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. 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

 * Jidanbo noticed that the other Gatekeepers were such good buddies and now they didn't even blink while one of their comrades was falling down so they might be under the effect of Aizen's Zanpakutō
