Hinomoto, which had been destabilized by World War I in 1989, experienced a resurgence thanks to technological advancements. Advancements in modern engineering led to the emergence of new modes of transportation, such as aviation, gasoline engines, and geomagnetic technology, causing railroads to become obsolete. However, a spirited group of "Raillords," embodied by vivacious girls, were determined to return the railways to their former glory. In Ohitoyo City, under the leadership of Suzushiro from Manoka Railways, the Raillords acted as humanoid control modules for their respective railroads. Through their concerted efforts and teamwork, they successfully revived the railways, ushering in a new era of transportation.
