No matter how dark the night, the sun will always rise. Kaya Fugeki is a teenage girl living in Enishi, an island at the northern tip of the Yamato archipelago. She brings the day to Yamato as the Archer of Dawn, granted powers similar to those of the Agents of the Four Seasons. The young goddess attends school along with the people she serves, yet nobody except for her handsome young retainer knows she is the country’s Day. Thus begins Kaya and Yuzuru’s story.
