Frighteningly fast overhead when Tiger Knee'd, leading to Baiken's extensive corner damage and knockdown when RC'd. The ability to go into this out of any jump cancellable normal, particularly her 2D, gives you an extremely powerful mixup tool whenever the opponent is in blockstun.
Done higher in the air, it can be used to delay her fall and bait the opponent into attempting a punish. It also has an extremely early and difficult FRC point which comes before the moves goes active, but will slow and change the direction of Baiken's aerial momentum, and has its uses in corner combos.
It is, however, extremely unsafe on block, and when TK'd, will leave you wide open if it is blocked. However, you generally won't be getting any reward off of this without meter anyway, so you'll likely be saving this for when you can covert. Terrifying.
Throw invincible 1~3F. Floats opponent on hit (untechable for 28F). Baiken is in CH state during move. Baiken is in crouching state during landing recovery. FRC timing 3~4F. Fastest possible TK Youzansen has startup 9F.
