On June 1, 2021, the original songwriter CCR and NAMU Animation signed a contract to use
the original work and agreed to produce an HD FULL 3D TV Animation Series
(11 minutes X 52 episodes).
The plan is to produce an animation called "NEW FORTRESS" (working title) in the slapstick
comedy genre that recalls the past through games that the MZ generation enjoyed in their
childhood, and to expand the Fortress world and the characters' personalities that were
only briefly shown in the game.
