This is a tribute to the Chun Li spinoff film. Yamai Ren is one of those characters who can be quite obsessive at times and is an obstacle for several characters. She isn’t really much of a fighter though and that’s why Chun Li would still crush her in a fight. The difference in their respective power levels is quite large and it’s a gap that can’t really be bridged right now. Yamai would need massive power ups in order to do that and I don’t see it happening. Chun Li wins.
