This boss is so badly designed it's not even funny. If you try to fight her "fair", you probably want to uninstall the game. She is impossible to hit because her ki doesn't drain at all. She can dodge literally infinitely, nothing she does drains her ki and she even blocks your heavy attacks when at under 10% ki. Even kicks are useless since she'll run away for half a second and gets full ki. She can do instant 7-8 attack combos while breaking out of your stuns mid animation, retreat to the other side of the arena to recover and instantly dash back with a three dash attack that has the most broken hit box in the history of gaming. You can't even heal because of course she has ranged attacks. On the flip side if you use parries, she's a walk in the park. She can't even damage you. Either rage inducing bs or a complete joke... Yea well designed boss...
