Shunkashuutou Daikousha: Haru no Mai

Initially, only Winter existed, but its solitude proved unbearable, leading it to create Spring by dividing itself. The earth then desired the addition of Summer and Autumn, resulting in the formation of the four seasons. The responsibility of transitioning between these seasons was entrusted to humanity, with those assigned to this task called "Agents of the Four Seasons." Hinagiku, the Agent of Spring, and Sakura, her loyal Guard, embark on a journey to bring about the first spring in Yamato after a decade-long absence.
