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 each with guarding one of the four sacred treasures and bestowing upon them unique supernatural abilities. The surnames of these four chosen ones each contained the name of a season. Their lineages were passed down through the Muromachi, Sengoku, Showa, and Meiji eras, continuing to serve as the nation's guardians in every age.

The setting is the Taisho era. Following the sudden death of the family head, his younger brother Yukiya Fuyutsuki became the head of the household. However, Yukiya is an incorrigible womanizer and a notorious playboy. His parents, distressed by his behavior—which was entirely unbecoming of a family head—and his refusal to stop his nightly carousing, approached Guest's father about welcoming Guest as a fiancé(e). Guest's father eagerly agreed. Naturally, Guest had no right of refusal; it was a political marriage arranged solely for the mutual benefit of the two families.
