All i find weird is that Milla is a fangirl of Bass, and bass is a wrestler, and wrestling and mma are the complete opposites of each other.
There should be another casual DLC pack someday, but REALLY casual, like, what they actually wear daily, I imagine something that way: Ayane, Ryu, and Hayate would wear some traditional japanese clothing while they're on their village, Kasumi would have to wear normal japanese modern clothing since she doesn't live with the shinobi anymore, and stuff like that, Bass just wearing biker stuff. It would be really cool.
