My entry for a contest at
They are Mana and Mahado, from YU-GI-OH! She is the spirit of the Dark Magician Girl, and Mahado the spirit of the Dark Magician. They are probably Atem´s (Atem is Yami´s real name) best friends and Mahado is also his guardian...
Many people ask if they are my fan characters NO THEY DON´T! They are official characters, here I have put a link to some screenshots of them from the anime ^^ (the images are from this site [link] )
