There is some support for Miki, now that you mention it. I think it's because she really does offer something V3 doesn't: a realistic, expressive Asian face. I do buy stuff for Miki. I would buy stuff for Koji, if there were any. (Though frankly, I don't care for Koji's body. I don't care for M3's body, either, but at least it's easy to morph.)

I would buy stuff for Miki and Koji. Though probably not pinup gear. I like Miki's casual clothing pack, stuff like that.
