Now the guardians are ready to do everything to prevent the appearance of Vanitas - the fifth season.

Bloom believes that the seasonal houses will be able to get the Winter Crystal and melt the glaciers. However, when the girl is on the verge of life and death, and the world is on the verge of chaos, who will perform the ritual of the passage of the seasons?
