The antagonist who initially was known for being a kind and gentle person, Fuma is forced to become a Dragon of Earth after his friend and twin star, Shiro Kamui, chooses the Dragons of Heaven. As soon as his destiny was awaken, he immediately attacked Kamui and killed his little sister Kotori, whom he had adored.
This is cosplayer Hagaren, who has done a very good job with Fuma as well as his sword. If anyone knows where Hagaren’s website is, please do point me in the right direction and I’d be glad to credit this photo. Great work! Thanks to Christina Applegate for sending this in!
EDIT: Thanks to Rossassen for giving us Hagaren's Deviant Art account!
