In a world where monstrous invaders from another dimension attack Earth every week, only to be spectacularly defeated by the colorfully costumed heroes known as the Dragon Keepers, a surprising truth lurks beneath the surface. The "monsters" are actually unwilling conscripts forced to participate in a staged battle for the heroes' glory. Go! Go! Loser Ranger! follows the story of D, a lowly foot soldier monster who has grown tired of this humiliating charade and decides to fight back. After witnessing the heroic facade crumble, D infiltrates human society with a daring plan to expose the Dragon Keepers' corruption from within. By disguising himself as a human and joining the very fan club that worships his oppressors, he begins a covert war against the organization. This action-packed series blends dark comedy with superhero tropes, exploring themes of class struggle, rebellion, and the price of manufactured heroism through its cleverly subversive narrative.
