If you don't have a nico account, the sum of the fight is: Kohaku on point with Hisui assist can call her in the air, it's plus frames, and it does no pushback. Half moon Shiki can 6AAA THROUGH SOMEONE'S COLLISION BOX and cross up from the other side. Both of these things are stupid.
Edit: Ken just pointed out something even worse lol. The combo counter DOES NOT STOP even after Kohaku is knocked down in the third round when Shiki combos both twins. It keeps counting and scaling until Hisui wakes up.
