Hello and welcome! It's so exciting to have a new player, and another CLAMP fan at that.
I'm Andrea, and I tagged you very briefly in the TDM (I was the Ashura), and then I got unexpectedly busy... sorry about that. I'm very excited to play with you more!
I currently play this obscure lady here, as well as Sebastian from Kuroshitsuji. I'm not familiar with Cordelia at all, unfortunately, but from your description she and Sebastian sound like the same person. Fellow hypercompetent can-do-everything-on-my-own perfectionist.
