Okay so in this recent chapter kirge was killed by a unknown person who just instantaneously sliced him in half and put his sword against kisuke's neck. Now who could this be. Many people have speculated that is grimmjow which is highly possible but I've noticed no one say anything about Ulquirra who said this to ichigo while turning to dust,"if u do not kill me, this will never end." soooo, that said I think it could be Ulquirra dont ask me how but I seriously don't think kubo would kill him off without developing his story more. And if does than he would do a flashback saying how he got back. Also I don't think it is Aizen especailly since he was taken to the lowest level of soul society and probably guarded pretty heavily. And also to show it could be Ulquirra did anyone notice the style in which kirge was killed? Sliced in half and the person elegantly and swiftly put his sword next to the neck of kisuke. I say if it was grimmjow he would've just gone in laughing hisarically and killed him off with a cero:noc: but I could be wrong any thoughts and is my theory plausible?
