You should take it as it's written
R.Mika didn't exactly appeal to me the first time i ever saw her, but seeing as every single new grappler ever made by capcom has continued to be topless muscle men I don't hold much hope for themcreating a new female grappler, so in the face of nothing I'll happily take Mika
also, keep in mind that the 6 confirmed peeps have been touched up to various degrees, especially Birdie, so I imagine she'd be redesigned a bit.
As an added bonus, if mika did make it, I'd probably attend fights with a bag of skittles so I can offer my opponents to 'taste the rainbow' if I beat them :3
