Well, if you look at whole story, Sora and Kairi are only 14, thus making them underage characters unfortunately. Simply making them older, posing them in a sexual or alluring situation is considered a loophole by the dA administration and it would most likely get removed once it comes to the administrators' attention and it's something that no want wants to argue about at all.

Thanks again.

(I deeply apologise that I couldn't reply to this comment for months, because I had to do other things on dA.)
