My vote HELL NO!!!!!!!
My Reason: I'm sick to the point of wanting to vomit of omg, lol I just met you five minutes ago ,but i'm in luv with you!! LOL! unbelievable, unrealistic, cliched love stories!*Looks at Tidus and Yuna*
Riku is completely fine the way he is. Which is single!
As a matter of fact I wish Kairi and Sora weren't interested in each other. I'm sick to death of characters being thrown together in movies, books games, etc just because it seems that society thinks if you aren't paired up with someone no matter how out there said pairing is something is wrong with you.
