Shunka Shuto Daikosha: Natsu no Mai [First Volume] (Dengeki Bunko) [Light Novel]

[Machine Translation] Thy name is Summer, thou who followest Spring - Once the four seasons, the gods, gave their power to a portion of mankind. Spring, summer, autumn, and winter. Those who manifested each of the seasons were called "agents of the four seasons," and those who gained the power became the seasons themselves, or in other words, the deities of the present people, while still being human. In the 20th year of the Meiji Era, the island nation of Yamato, located in a great sea, was hit by a cataclysmic earthquake. Hanaba Hinagiku, the young goddess of spring, returns after ten years. The militant faction "Hanatoshi" attacked in summer and autumn. And then, an unprecedented joint front of spring, summer, fall, and winter. The Four Seasons camp was victorious after many hardships, but a problem arose at this point. The Hazakura sisters, who were the substitutes for Summer, became the first "twin gods" in history. Is this a good omen or a bad omen? The season is summer. Now, once again, the story of the agents begins.
