Well it was nice seeing Shishigawara’s never-give-up attitude and guts, and it was nice seeing Ikkaku lecturing him on not throwing his life away for someone who wouldn’t do the same for him, but other than that I felt the main part of this chapter was one big deus ex machina with Tsukishima revealing that he can also swap battlefields into his favor or insert himself into Byakuya’s sword. It’s overpowered and the limits of his abilities have been completely shattered as he shows that he can manipulate reality into whatever he wants by using parallel worlds. That truly is the power of gods, and hopefully his ability doesn’t become too much more ridiculous.
At least the battle won’t be as one-sided as the other fights so far, and once Byakuya releases his full power it should be good fight. Of course he just has to avoid getting touched by Tskishima’s sword, else he’d be completely erased in an instant, or worse — turned into an ally. It would be troublesome if his own zanpakutou turned on him, but it’s still unlikely Byakuya will be defeated with all his skills and battle experience. Tsukishima may have a stupidly overpowered ability, but he’s not on the Aizen level yet and really he’s only shown his proficiency in screwing around with people by controlling reality itself. He’s started giving himself all sorts of knowledge too, but it’ll be yet to be seen whether that actually does him any good.
