One of the products created by Tecmo Koei in relation of Dead or Alive 5 is a "I'm a Fighter" necklace.
The necklace features the game's tagline "I'm a Fighter" printed in white and red on a cut piece of clear plastic. The pendent is hung from a silver-metal chain.
The necklace is not available for retail, but Team Ninja have often used necklaces as prizes in official Dead or Alive 5-related contests.
