Aizen: *shocked* the hoyogku it can speak?!

Hoyogku: you aizen have done everything wrong and I can't take anymore your will is only 20% of his only on the best day I'm tired of your god hood obsessed ass!

Just then cracks appeared all over aizen as he screamed in pain.

Aizen: *pained*AHHHHHHHHHHHHHH!!!!!

More and more cracks appeared on aizen as his form shattered and his original form was on the ground as the hoyogku floated above him as it floated towards ichigo who was still shocked as to what was currently happening as it floated right in front of him it stopped about a foot apart as she said.

Hoyogku: all that power just to be sacrificed you worked so hard rest leave it to me I'll grant your wish to protect everyone.

Just then the hoyogku glowed a bright purple as it flew to his chest and sank in as if it was a ghost he couldn't see it as he was about to examine his body a bit more he saw aizen move he got ready again as he saw aizen stand up fully again blood coming out of his mouth slightly as he said.

Aizen: *pants* I'm not done yet.

Just then shots of  kido came out of aizen as he fell to the ground as he throw up blood.

Urahara: well well well how about now?

Aizen: kisuke.

Ichigo fell to the ground as he felt so sleepy all of a sudden as he blacked out he heard.

Urahara: rest now ichigo as your teacher I'll take on the responsibility of this.

He then began sealing aizen.

Urahara then explained everything that happened.

Yamamoto: if that is the case then I will entrust both you and captain unohana to take care of the boy now.

He said standing up just then captain unohana smiled her evil smile as she said.

Unohana: *evil smile* captain commander you aren't fully healed as such you WILL be staying here to heal til then you are not aloud to leave.

Urahara put his hat down to cover his face as to not see what happens next as the captain commander wanted to talk back but pain flared in his body again for once he may listen to the doctors instructions.
