It's a cover for the 57th volume of Bleach. Yes, the volumes have titles. It's title suggest that this volume will be about recovering from the last battle and the like.
I dont remember who mentioned it, and Im lazy to search back xP but its quite interesting that Shutara has those boney arms that are somewhat remniscent of Nnoitra, not to mention the moon shaped horn thing, (it looks like horns on Nnoitra) ...probably just coincidence. :3
Maybe they joined with their zanpakuto's like in that one filler movie with the guy who became one with his sword so he would be super powerful but everyone says not to do it, maybe zero squad did it lol and thats why they don't have zans
Your idea is way cooler than mine paul! Id like to see that more, it would show such a level of synch with their souls and zanpakuto that I would expect no less from squad 0. Hope this weeks chapter shows us something exciting or at the very least a ton of new info
I say aizen can beat everyone in zero squad all by himself at the same time
