Ichigo's recent battles with the Arrancars have proven that if he wants to protect his friends he must get stronger, and the only way to do that is to control his inner Hollow. Ichigo turns to the Vizoreds, ex-Soul Reapers who have been Hollowfied, to teach him. But before his training begins, Ichigo must do battle against his Hollow self--winner takes his soul.

"As Aizen strolls through Karakura Town, Ichigo undergoes furious training in order to master the one technique that could bring an end to the conflict. But when the battle is finally over, how will Ichigo's world have changed?"--From publisher's web site.
