Sentai Daishikkaku

Thirteen years ago, the invading Monster Army was defeated almost immediately, but the public never learned the truth. The surviving foot soldiers were forced to stage weekly battles against the Dragon Keepers so the “heroes” could continue earning fame while the monsters were humiliated for entertainment.

Footsoldier D finally grows tired of the arrangement and infiltrates the Keepers in human form, intending to destroy their system from within. He quickly discovers that the organization worshiped by the public is filled with internal conflict, authority, and violence, while some humans also want it changed. To defeat heroes who control both power and public image, D will need to become a better actor than he ever was in the weekly performances.
