it's a little hard because i'm not a pop'n player by nature, but
- in general i favor the abstract ones like papyrus and yima and tent-kant
- i like machiko, she is so cool....
- i like masamune, he is so cool... if i played pop'n i would pick him as character probably. ookami-boy is also good on the boys' side of things
