WAIT! Zangetsu isn't a Vasto Lorde?! (I'm kidding). I think Ukitake and Shunshi are (of course) going to show up together to fight Ywach, similarly to how they confronted Yamamoto while Ichigo was fighting Byakuya, except this time their actual capabilities will be shown off. I'm also hoping for an eventual explanation of what being a "special war potential" actually means because it's still a bit vague at this point.
