Its from Bluebird's Illusion a game they will NEVER release in America. They stopped making it because they did not own the story and where not allowed to use it. At least that's what I heard and yes Ed is a Sin he's the Bluebird's Illusion's PRIDE.

Ed's cute as a sin.... what do you think happened to him?

naw he's a sin. i think its in the one video game they made. not sure its in america yet tho -EE2

that's just a fanart ed's not a sin in this picture i think he is supposed to be the philosophers stone

Its sad that my Edo-chan is a sin...
