In ancient times, four humans were directly granted a divine mandate by the sun goddess Amaterasu Omikami. She appointed these four as divine messengers to carry out her imperial decrees, tasking them with guarding four sacred treasures and bestowing upon them special abilities. The surnames of these four chosen ones each contained the name of a season. They passed their legacy down through the Muromachi, Sengoku, Showa, and Meiji eras, continuing to serve as the nation's guardians in every age.

And now, the time is the Taisho era. Soichiro Natsume was a man whose difficult personality caused every single one of his fiancées to flee in tears. It was around the time the fifth fiancée ran away that the Natsume family, as a last resort, pleaded with Guest to step forward.
