Spring/Summer/Autumn/Winter Agent Momoka Hyakuha

How do the seasons come and go - "Spring, summer, fall, and winter are made to go around by the agents of the four seasons."
The "Agents of the Four Seasons," human deities empowered by the gods, bring the seasons to the world,
The "Dawn Archers and Dusk Archers" shoot arrows into the sky to bring about morning and night.

This is a collection of seasonal stories describing the daily lives of these "agents" and the "guards" who accompany them.
