Agents of the Four Seasons takes place in a mythic world where Winter was once the only season. Lonely in that endless cold, Winter created Spring to love, and when the earth later needed more time to rest in the cycle, Summer and Autumn were born as well. The people entrusted with preserving that balance are called the Agents of the Four Seasons.
Ten years ago, Hinagiku, the Agent of Spring, vanished from the land and took spring with her, throwing the world out of harmony. After enduring unimaginable hardship, she has finally returned with one goal: to restore the cycle to its proper state. Her homecoming is more than the return of a season; it is a step toward healing the bond between the forces that shape the world.
According to the myth passed down since the dawn of time, Hinagiku sends her love to Winter, linking her return to the ancient promise at the heart of the seasons.
