No. The creators of Anime Cross 2, @TheSeikirin and @Vader23000 create the codes.
Codes in Anime Cross 2 are a staple way to make quite a lot of money in Anime Cross 2. They provide great amounts of experience and great amounts of coins. Also codes never expired unless they are leaked and the admins find out about it.
Codes come from the Twitter page of @TheSeikirin and @Vader23000. They are both excellent developers on ROBLOX and I recommend following them for leaks from updates and more codes.
