text: Aya Fuse Aya Fuse (pronounced EYE-a FOOZ-eh) is the protagonist for the book Extras. While the world suffers from a metal shortage, she discovers a secret stash of metal, which she believed was to be used for weapons. She then allies with Tally Youngblood and her friends to find out the purpose for the metal stash.
  Moggle
  Moggle is Aya's hovercam. He gives Aya someone to talk to, and is also helpful in many situations in the book. Moggle follows Aya and he takes photos of the Sly Girls for Aya's kick stories.
  Hiro Fuse
  Hiro is Aya's older brother. He is popular in their reputation-based city and is invited to the Thousand Faces Club, which consists of the top 1,000 popular people in the book.
  Frizz Mizuno
  A leader of a clique called "Radical Honesty", where the members must have a brain surgery that gets rid of all deception. He becomes Aya's boyfriend. His surgery did not agree somewhat with the story as he was unable to hide anything, and it especially did not agree with Tally. She convinced him that he was not strong enough to tell the truth all the time (he took the surgery because he lied constantly, especially to girls).
  Ren Machino
  Hiro's technologically gifted friend. He installed the mods on Moggle to make him waterproof, able to fly and carry Aya, and fitted Moggle with artificial intelligence.
