Ok this was a very funny and kinda light-hearted chapter. I knew Kisuke would come and save Yoruichi. We gotta see more of that partnership. So I kinda like the power up. I mean she was never really much about using her weapon, even her Shikai. She is more of a martial arts fighter and her body is her weapon. So the power up does kinda make sense.
I also like the mention of the five people that can't be calculated. I mean it does make the story more interesting that Ywach recognizes them as special. Kisuke will probably get involved in this fight somehow, since I don't think it's gonna be over in a couple of chapters.
