God Eater Burst's official blog has just announced that it will be having DLC costumes of Asbel Lhant and Cheria Barnes from Tales of Graces/Tales of Graces F.
The only one they actually announced is the Asbel costume. The Cheria costume was given in the form of a little mystery costume here, though it's obvious it's her. The DLC will be available on February 10, 2011.
