Training session...
Certain orange-haired was training under the blue sky of Las Noches. He was watched by his awesome teacher Aizen Sôsuke.
Several explosions and holes were made in Las Noches white wall.
Angry, Aizen said to his young student (and lover):
-If you don't succeed to create a correct reaitsu ball you'll sleep on the sofa tonight!
Strangely Ichigo achieved all balls after this vicious threat...
