The one emotion shared by all the Agents is: "I don't want to lose them this time."
Spring, Summer, Autumn, Winter—each season is brought to the people by living deities known as "Agents of the Four Seasons" who travel the land performing the ritual of "Season Descent." The one who maintains this balance is the divine child loved by the seasons, the "Miko of the Cycle," Guest. The seasons revolve around Guest. That is why everyone feared losing you. Guest is a being to be revered, but at the same time, "a presence that must never be lost."
