A Kingdom Hearts yaoi pairing between Xigbar and Demyx. While not half as popular as the well established pairs such as AkuRoku or SoraRiku, it does have a fair amount of popularity in the Kingdom Hearts fandom. It is typically seen as a crack pairing, due to the fact that over the course of Kingdom Hearts II Xigbar and Demyx have no contact with one another.

Where or why it originated it a bit obscure. It seems to make most sense that it originated from the popular theory the Demyx is one of the youngest members of Organization XII and Xigbar is the eldest. This is slightly akin to AkuRoku, seeing as Roxas is 15, and Axel is typically thought of to be an adult.

Another reason might be that Xigbar's voice carried the tone of a steriotypical 'surfer dude', while Demyx's element is water.
Person 1: I'm looking for some interesting crack pairs, can you think of any? I'm thinking maybe somthing with Demyx.

Person 2: Well there's always Zemyx, XemDem, and XigDem.
