With the Bounts defeated, Ichigo and his friends settle down to what they think will be an ordinary life of school and battling Hollows. But things take a turn for the unusual when a new student arrives at school who seems to know all about Ichigo-including the Hollow within him that's getting stronger all the time. With a menacing Spiritual Pressure descending on Karakura Town, Isshin and Urahara are worried that someone is creating an army of Arrancar-Hollows with Soul Reaper powers-and that someone may be former Soul Reaper captain Sosuke Aizen!
