I've read XXXholic and a friend of mine had Chobits and I've seen some CCS anime. I haven't read Tokyo Babylon or X because I didn't like their old art, but now I really like it so I might give it a try. I gather that Seishirou (who had a cameo in TRC) is actually from TB? I'd like to read it. I have heard many wondrous and disturbing things about Seishirou/Subaru Though I also heard that X is on hiatus, how cruel.
