Two sleepless teenagers find kinship as they escape to their school’s astronomy observatory. Unable to sleep at night, Ganta Nakami is cranky in class and unpopular with his classmates. He discovers that the school observatory, once used by the now-defunct astronomy club, may be the perfect place for a nap—but he's not alone. Fellow insomniac Isaki Magari is willing to share the observatory with Nakami, and a friendship between the two begins as they bond over the most unlikely things. Magari is back, full of energy and ready for anything. As the holiday season approaches, she and Nakami prepare to spend their first Christmas together. As the year comes to an end, Kurashiki Sensei drops by Shiromaru’s place and the two enjoy a peaceful evening together. On New Year’s Day, everyone gathers at Shiromaru’s arcade to help clear the snow and ring in the new year!
