For centuries, the task of bringing the seasons has been carried out by the Agents of the Four Seasons, individuals whose god-like powers make them an easy target for covetous groups. One such group, the Rebels, orchestrates an attack on the Agents. To save the others, the Agent of Spring, Hinagiku Kayou, allows herself to be captured and disappears from the face of the Earth. Despite the lack of help, even from her own village, Hinagiku's guard, Sakura Himedaka, believes she is still alive somewhere and refuses to give up the search.

Against all odds, Hinagiku is found 10 years later. However, the traumatic event caused a massive shift in her personality. Thanks to Sakura's encouragement, Hinagiku gets the courage to summon the season that was once lost. In order to move forward, the duo must face a past that haunts them and demons willing to destroy everything to achieve their goals.
