Firstly, the item is not mine. But I found someone wanting to sell their code on ebay. I can't vouch for whether to code is used or not (The description says it's unused), but I just wanted to let people in the US/using US versions of Dissidia Duodecim that this code is available, I'm aware that it's hard to find cheap.
Bidding as of this post is $0.01.
