Insomniacs After School manga volume 2 features story and art by Makoto Ojiro.

The school forces the insomiacs' re-formed astronomy club to operate as a proper club. The problem is, neither Nakami - its new president - nor the club's adviser know a thing about astronomy. Yui Shiromaru, once a prize-winning astrophotographer, now the manager of a small-town video arcade, might just be the person they need.
