For the last thirteen years, the Malevolent Beast Legion has surfaced beneath their hovering citadel every Sunday to push forward their ambition of dominating the planet. Fortunately, the Dragon Guardians arrive to avert disaster! After crushing most of the beasts in their first onslaught, the defenders now regularly appear to eliminate any lingering opposition. Unknown to observers, each subsequent clash has been a staged spectacle orchestrated by both factions: the Dragon Guardians gain renown and honor from battling fictitious foes, while the remaining frail monsters—collectively known as Dusters—receive a reprieve for another day.
Sentouin D, a Duster weary of enduring this disgraceful existence, departs the citadel to challenge his destiny. With unforeseen aid from the enigmatic ranger Yumeko Suzukiri, he learns that defeating the Dragon Guardians hinges on their Sacred Relics—ultimate armaments vital to the rangers' metamorphosis and distinct abilities. Joining forces with Suzukiri, Sentouin D infiltrates the stronghold of Red Guardian Sousei Akabane; he must defy all odds to rescue his kind from humanity"s merciless grasp. Their mission is fraught with peril, yet hope glimmers as legends of their courage inspire countless others to join the rebellion for all.
