The official Tales of the Rays Twitter account has revealed a new anime, apparently named Tales of the Rays Theater. This will be a short gag anime unrelated to the actual Tales of the Rays game. Production is mostly complete, and information about when and where it can be watched is planned to be revealed at Tales Of Festival.
