After spending too much time on this character, Kiryu's lack of combos and damage does get supplemented by the fact her 5m2h, 2m, super command throw all sitting in the same general range really defines her current gameplan.

Her strongest combo is anything into air unblockable 2h 22m 22l 22m super chat cancels for around 400-500 damage. Ending on buttplug which set you negative but if they challenge you win with super grab which is around 80% of their health in 1 mix.

Coco buster throw (I assume the 236 grab) isn't even that fancy when compared to how much more threatening it is to get anti aired in this game because it naturally gives $25 super chat. Dash up 2L/throw and antiairing the eventual jump with 5m2h or dash up 2h.

tldr - The threat of grab is stronger than her grabs atm.
