Kubo must have some pretty nice humiliation prepared for this guy at this point, it´s the only reason i see right now. Any guy in the rescue group can beat him.I'm still annoyed that Yami is still alive somewhere. Hes absolutely useless now. He was the lowest ranked Espada and I doubt he would be of any real use to Aizen in the coning war unless he was upgraded.
Personally i want to see Chad kick his ass.
