Kyoko is a good, and I always enjoy threading Makoto and Kyoko. I'd be up for tossing Makoto at any of your dangans, as well as the rest of mine! (Makoto and Sonia would be cute friends, as would Aoi and Sonia!)

As for DDLC/Dangan, that's a good idea! I also have Sayori, who would be good bouncing off of Kyoko or Sonia, or even DR2!Chiaki!

I do have plurk as well, if that would be easier to toss some ideas around on!
