Fate/Extra CCC takes place in the cyber world as a continuation. The themes of the story are a girl's passions and eros. Something has gone awry though and the male or female protagonist must make their escape from the world. It also appears that Sakura will be playing a bigger role in the story this time around with a strange magician that looks very similar to Sakura. There are also many recurring characters in the story. Leo and his servant appear to be in the cyber world and are trying to escape. Rin Tosaka returns as a magician and not a hacker while Shinji and the student council work at hacking. Rani is confirmed to be in the game as well with an unknown role.
All the recurring servants are known to make a return with alternate costumes. Saber sporting a wedding dress while Caster comes in a new Gothic Lolita wear. Amongst these servants are a newcomer by the name of Gilgamesh from Fate/Stay Night.
