XD Yuki emits poisonous gas from his whole body. Like Smoker in One Piece, he can change his whole body into the poison, but he has to be really careful when he shakes hands because he can't always control it. He wears gloves so that he won't kill anybody by touching them. Yuki is also afraid of fire because he's flamable! And, unfortunately for Yuki, his best friend smokes!

Yayy, an original character!! Eee, you're right, that scarf is cute on him. :D And might I ask... WHERE he emits his poisonous gas from? lol Just curiousss... XD
