OK I think everybody, who did watch Yu-Gi-Oh! 5D's once, knows Leo. The cute and jittery twin brother of Luna. There're some, who don't like him, but there're are also a lot of Fan of him.
I am a fan. I like his nature and his kinda childish, but Merida - Legende der Highlands and determined way of acting. And he's sooooo cute. Are Du with me? (^.^)
How ever. Don't Du think it was unfair, when krähe became the 5th signer, instaed of Leo. Leo did deserve it more. But in the end he finally became the 6th signer with his really cool new dragon. Life Stream Dragon.
