Shadow here.
Well, first off, this isn't really my work, its Eminai's but I saw her make it on Photoshop. X3 And I have the honor of uploading it. -grins- But anyway, you must be wondering what this whole picture is about? Well, ok, first off the Sora plushie is from this [link] (He's so cute!) And Xemnas of course grows attached to his Sora-kun and clings onto the plushie obviously stating: Mine!

Obvious pairing? Goodness. I wonder who it could be? Don't be shocked my friends. There are weirder things out there.

Besides. I like this paring. Its so rare. XD Never existed really. But now... Heh. Xemnas and Sora could.

Eminai: Eminai here. I apologize beforehand if my typing is somewhat... erratic. I'm half blind and running on a couple hours of sleep. Cursed school. However, since Shadow actually uploaded this picture, I feel an explanation is due. It all started when I was first introduced with Kingdom Hearts way back when in junior high (Goodness, makes me feel old...). Shadow has kindly showed me the final battle between Sora and Xemnas. Keep in mind, at that time and moment, I was a bit of a newbie in the KH universe. In fact... I didn't think I knew who Kairi was. O.o So, then came Valentine's Day. I was going to draw a comic for Shadow as a gift but then came the task of satisfying her. What in the world does she like? Simple: Kingdom Hearts, and (somewhat unfortunately) yaoi. Right then on the spot I thought of the final battle, and considering good guys got paired up with bad guys quite often, the strange pairing of Sora and Xemnas was born. Yes, I did draw a Sora/Xemnas comic just for her and suffered (I was twitching while drawing the kissing scene... Ugh...), and yes, the love for the pairing still continues to this day. So there you have it: the origins of this madness.
