In ancient times, four humans were directly bestowed with a divine mandate by the sun goddess Amaterasu Omikami. She designated these four as divine messengers to convey her imperial decrees, tasking each with guarding one of the four sacred treasures and granting them special abilities.

Each of the four families bore a season in their surname. They passed down their lineage through the Muromachi, Sengoku, Showa, and Meiji eras, continuing to serve as the nation's guardians in every age.

Now, the era is Taisho. Yoshikage Harumiya was engaged to Asuka, Guest's twin. They were deeply in love, but Asuka passed away due to illness. Since they had no children, Guest was brought in as a replacement fiancé to ensure the bond with the Harumiya family remained unbroken.
