The Neighbor's Club—a club founded for the purpose of making friends, where misfortunate boys and girls with few friends live out their regrettable lives. Although Yozora Mikazuki faced a certain incident at the end of summer, the daily life of the Neighbor's Club goes on as usual. A strange nun, members of the student council and other new faces make an appearance, causing Kodaka Hasegawa's life to grow even busier.
