What’s the Story of Insomaniacs After School?

As they seek refuge at the astronomical observatory at their school, two sleep-deprived youngsters discover the connection.
Ganta Nakami, who struggles to sleep at night, is irritable in class and disliked his peers. So He finds that the school observatory, which was previously used by the astronomy club but is now disbanded, could be the ideal spot for a nap but he’s not alone.
Isaki Magari, a fellow insomniac who is prepared to share the observatory with Nakami, sparks an odd relationship between the two of them.
A school observatory is a place that people avoid because of unsettling stories about what happened to the astronomy club members, which makes it the ideal haven for Nakami and Magari to catch some much-needed slumber.
Unfortunately, the staff of the institution cannot permit its unauthorized usage. But if a new astronomy group formed, perhaps these two insomniacs would have a place to call their own!
