I feel like Asian women are extremely brutal when it comes to catfights. I've seen some Chinese videos where the wife pummels the mistress, strips her nude and cuts her hair on the street in front of everyone and no one steps in to stop it. Must be a cultural thing where people see the mistress as a whore and think she deserves what she got.
As far as blood goes, women get very aggressive when they start leaking. I recently saw a reddit video where a girl got hit and started leaking and then went off on the other one until she made her a bloody mess. Her opponent kept saying sorry and she didn't mean it, but the chick was like nope you made me leak so I will make sure you bleed more than me.
