I'll give points for Ichigo being confident and wasting no time in attacking Bach (reaching for his sword no less). Behold the powers of being whatever the author says you are a mutthybrid! And what's this? References to the Ulquiorra fight, only 300-odd chapters later? It's something I suppose.
But the art continues to be ink splots everywhere, and while Grand Rey Cero is cool, it just looks like Kubo just did some light sketching. It's one of those things, like the actual Getsuga Tenshou, that would look better in the anime.
And really? We're doing the "strong attack seemingly wounds main villain who was previously invincible" cliffhanger again? Bach is just going to regenerate or reveal his TRUE power, or something like that.
