The Miracle is a giant,Kubo does seem to be going for a fairy tale feel, the Miracle is a giant and he is blowing them down like they are three little pigs houses.
He took down Byakuria, Renji, Rukia, Shinji, and Momo in one shot. I am glad that Shinji has learned lesson about blabbing his abilities I hope, though Hinamori is so naive, how did she get to the rank of Lt., if she is naive enough to show mercy to an enemy. You get your self killed that way.
Sounds like this battle is going to last about 10 chapters, where is Ichigo, it seems this would be the time for him to show up. What other heavy hitters am I forgetting about, Kenpaji is still recovery, Aizen is still tied up, maybe Urahara, other than that Ichigo is the only person I can think of that could show up to turn this fight around.
