If you didn't know already, I'm the picture hunter of this club. :3 So I just post pictures regularly. :3
There're no Yaoui pictures of Dark and Dai, 'cept those made my fanartists. Only picture that could be interpreted as Shounen Ai. But being the DN Angel Fangirl I am and not liking any of those two terms mentioned before, I like to believe that Dark and Daisuke just share an incredible strong bond. Being one and the same person. But I see at as bond between two best friends or brothers, nothing more. :3
After All, Dark could be seen as a Niwa, instead of -perhaps- a Hikari. =3
