I understand you're terrible generic combination.
However as I said, If Kimi tanks the Pillar by hooking onto the ground, its already useless and even if he doesn't, Mei isn't traversing the distance Water Dragon would place between them, before Kimi (who would barely be fazed) recovers and proceeds to avoid anything she throws.
HOW can he hook onto the ground if the ground is getting destroyed in the process of Mei using her Water Pillar? Just explain this to me. And of course he tanks it, it's not meant for killing. It's meant for creating an opening for Mei. Kimimaro being engulfed by a huge body of water, mid air, is useless.
And Mei has full control over her Water Dragon Bullet, which was shown in Kage vs Madara. Madara was caught and Mei simply guided him into Ay's attack. This time around, she'll simply guide Kimimaro into her on own Youton or Futton.
Kimimaro has NOTHING to get past this combo, because he won't be even given a chance to get close to Mei.
Words speak louder than dislikes my boy.
Mei is the one who will control the whole fight from the very first second. It doesn't matter if Kimimaro is better in CQC if he's not even getting close to her.
