One of the best aspects of Bleach is the factions the characters are divided into. Ichigo's Team Karakura, the Gotei 13, and most recently, the Wandenreich. In the Arrancar Saga, Tite Kubo introduces the Vizored. A group of mysterious yet colorful Soul Reapers that were exiled from the Soul Society and wear Hollow masks. The Vizored train Ichigo to use his Hollow powers and later on they join the battle against Aizen and the Espada.
