I also like them all. xp Though if I had to pick one, it'd be Kaname. I relate to him the most and he makes me laugh the hardest. Everyone is great though. The twins are probably next for me. They're so blunt and rude. xD Oh, and I really liked Fuyuki. I hope he's in more chapters. =]
Even though Chihiro is the main reason I started to watch the anime, I think I like Akira the most! I also like Azuma-sensei and the main five, but not the kouhai girl.
I ♥Two Syaorans from Tsubasa RESERVoir CHRoNiCLE and TRC!!!
Defiantly Shun. He's just so sweet and adorable and thoughtful towards his friends. I would honestly love having someone like him as a friend. ♥ I also sometimes find myself relating to him a lot, especially during the latest episodes.
Chizuru is a close second though; at first I thought that he was... too much. But after a couple episodes he REALLY grew on me, and I found myself loving every moment he's on screen. He's just so bright and endearing.
.... I guess I just have a thing for "sunshine-y" characters.
