Mikado sadly only knows one of the possible throws. With the Naginata, her signature weapon, she can break her opponent's neck. I can cheat her into using the others, but let's talk about a Story mode oddity first.
Neck breaker demonstrated by a fully battle damaged versus Mikado on a clean story Mikado.
In the second game, all four limbs and the torso can be damaged. This is marked with either bloodstains or bandages.
Story damage is in the game's files and code, for all six starting characters' versus outfits and the four unlockable characters from Slash mode, too. This is despite that none of them should be in Story mode.
Uno Reverse Card! This is what Mikado's story outfit looks like with all five damage points.
Mikado, that illegal! You can't use throws in Group Battle Mode!
