The guests that Aniplex are bringing to Sakuracon are big fans of Bakemonogatari and Nisemonogatari. They will be holding a special screening of the show at the con, and they'd like some cosplayers to help out!
Volunteers must have costumes from either Bakemonogatari or Nisemonogatari, with an emphasis on the main five girls. You must have a completed or close-to-completed costume photo uploaded on your ACParadise account for review. More details to be given once you've applied.
