ah, i am half way thru the comments here, but before i keep going i want to have my own input, put in heh.
Like many have said, i like both Yuki and Kyo. But, my difference is that i'd like to see her with both, and beyond that i can see her with both. It's obvious that both Kyo and Yuki care about her, and they both stand up for her. In the series (mind you that i may make mistakes, i've only gotten to see the whole of the series once) all those things that Yuki has, and is given... he does not want, and he's said that. He wants to change, and i think he would rather work for what he has. Like he had to work to become a well trained fighter, i mean you are not born with the ability.

As for the fan club, i get the feeling it's coming was not his idea(and i have to say i am peeved that a whole episode was dedicated to the club and it's president *seethes*) Eh, i dunno, i see alot of good in Yuki, and i see that while she can help make him a better person, he could also make her happy. and seeing her happy i think would make him happy. He's had a soft spot for her since the begining anyway, like when he brought her to his base. I really don't see yuki as emotionally detached as everyone makes im out to be *looks troubled* i see much emotion in him, but it's more expresed inside, rather than out. and the only person he shows it to IS Tohru
Now as for Kyo, i don't relly need to explain. much of how i feel on him has aready been explained. Just his contolled anger is a drastic change from the whole he made in Tohru's ceiling. I think just being with Kyo would make Tohru happy, and a happy tohru is a happy kyo, so.. yeah there ye go, and as for liking his character, heh what's not to like ^_^ you get the outcast, the cutie that he is, adorable rants that he makes when he tries to hide how he feels, and a guy that needs picking up from a tough past!
well that's my two cents for the moment, probably more to come tho ^_^
