For the past 13 years, the Nefarious Monster Army have appeared beneath their floating fortress every Sunday to advance their goal of conquering Earth. Luckily, the Dragon Keepers are here to save the day! Having defeated the majority of the monsters during their initial invasion, the heroes now routinely show up to clear away any remnants of resistance. Unbeknownst to the public, however, every fight beyond the first has been a deliberate show put on by both sides: the Dragon Keepers reap the fame and prestige from fighting imaginary enemies, while the surviving weakest monsters, altogether called Dusters, are allowed to live for another day. Sentouin D, a Duster tired of living this life of shame, leaves the fortress in an attempt to overturn his fate. With the unexpected help of the mysterious ranger Yumeko Suzukiri, he discovers the key to defeating the Dragon Keepers lies in their Divine Artifacts—ultimate weapons crucial to the rangers' transformation and unique powers. Teaming up with Suzukiri to infiltrate the garrison of Red Keeper Sousei Akabane, Sentouin D must defy all expectations to save his species from the cruel hands of humans.

Seishuu Handa is an up-and-coming calligrapher: young, handsome, talented, and unfortunately, a narcissist to boot. When a veteran labels his award-winning piece as "unoriginal," Seishuu quickly loses his cool with severe repercussions. As punishment, and also in order to aid him in self-reflection, Seishuu's father exiles him to the Goto Islands, far from the comfortable Tokyo lifestyle the temperamental artist is used to. Now thrown into a rural setting, Seishuu must attempt to find new inspiration and develop his own unique art style—that is, if boisterous children (headed by the frisky Naru Kotoishi), fujoshi middle schoolers, and energetic old men stop barging into his house! The newest addition to the intimate and quirky Goto community only wants to get some work done, but the islands are far from the peaceful countryside he signed up for. Thanks to his wacky neighbors who are entirely incapable of minding their own business, the arrogant calligrapher learns so much more than he ever hoped to. [Written by MAL Rewrite]
