Kazuma Hoshino is preparing himself for a new stage of his life as a teenager. Because of his brother Ayumu's weaker than average health, their parents thought it best for the family to move out from the city to a more rural environment.

This hardly sits well with Ui’s friend Ibuki who swiftly kicks Kazuma and sends him on his way.
