Future Card Buddyfight DDD ( X Reader OC )

This story is a fanfiction of Future card Buddyfight DDD. It's a new aired season after Future card Buddyfight 100. This anime contains new characters, but I would recommend watching the anime first since this story will give out spoilers to the episodes of the anime.

(I do not own the characters of Future card Buddyfight DDD or any of the Kantai Collection characters.)
