I like Sakura and Touya.
Sakura because, well, she's just WAY too cute. I love her personality, especially. And the way she goes "HHOOOEEE" and "hanyaa" is just so adorable...*huggles* ^_^
And Touya, because he's a really important character in the series. What happened to him was really sad though... he made the biggest sacrifice all series long. (Which I'm not going to reveal, lest I spoil it to others)
