Uh, I think it's a nice picture, showing Dark caring about Daisuke. I don't know the manga, just the anime. Cute picture. I like the colouring. Their hair is done nicely, as are the creases in the clothes. [For the record I can't see Dark and Daisuke as a shounen-ai pairing, and to my mind nothing of the sort comes across in this picture.]

In a sense you can see why they asked due to Darks expression as he's watching Daisuke sleep. *perv* It's like come with me my little child. Nice pic though.

Oh corse it's not yoai! That's in book ummm 5!
