I am disappointed with Naruto since Sasuke just decided to be good again. Almost nothing happened in a year, this final battle is moving very slow, and now it's on hiatus. I hope Madara can save the series finale because Obito really disappointed me. Now that we know Sasuke ain't fighting Naruto, there's only Madara left. I guess Naruto will became the sage (without rinnengan) after absorbing all the bijus somehow, and Madara will fight with his infinite chakra, rinnegan + wood jutsus.
It's not clear to me, but Dangai Joue did recover from the wound in his hand, maybe Komamura also has that kind of hability when in human form. He was already hard to kill when he had a heart, imagine now.
We've seen Ayon do a lot of damage on the Fukutaichos, but even him couldn't kill opie. Also, when Opie fought Ichigo he said he could used blut to defend against a bankai, but the prob was Ichigo's and Tensa's speed. So if blut can defend bankai attacks, maybe she had took damage, but not enough to die, it's gonna be like who can take more damage, because both attacks are devastating.
I think she used her explode on the sword to prevent it from hitting her with full strength. Also, she might have used her blut for defense. She must be good at it, since her blut would be pointless for lang range attacks.
