sorry but there's nothing of that sort tmk. It's all hand-drawn so only way is to have someone go through every frame & recolor.
As stated before, there's no real way to censor anything in this game. Depending on who you're playing, the closest you can get is playing with certain color palletes but thats about it really
Thats like Shadow FightSpeaking of palettes, they could issue a #000000 for every color field for a quick and easy "censor" that will turn everyone into silhouettes:

But I don't see a strong enough reason for them to bother.
