White Invasion

Prelude
Sōsuke Aizen finishes addressing the intruders of Las Noches. He then calls for the top three Espada (Coyote Starrk, Barragan Luisenbarn , Tia Harribel ) and their Fraccion to accompany him to Karakura Town , and leaves the 4th Espada, Ulquiorra Cifer in charge of the castle while he's away. With that, Aizen, along with Gin Ichimaru and Kaname Tōsen leaves via Garganta to the Human World, where the Shinigami are waiting for them.
