Wind-up Nanamo already exists. I don't know how to get her, but the data is there. Personally, I want a wind-up Yugiri!

I also want more pet like minions with clever interactions, like when the Moogles dance together, or the Wind-up Bahamut and Louisoux do battle. I was squeeling when I noticed that my Wind-Up Succubus would cling to my shoulder as I ran around, not letting go for anything. I want more minions that have these kinds of quirks.
