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. Nakami discovers that the observatory, once used by the defunct astronomy club, may be the perfect place for a nap--but he's not alone. Nakami and his new friend Isaki Magari find comfort in each other while coping with insomnia. After discovering the source of Magari's insomnia, Nakami and Magari implement a new nighttime routine, hoping to improve their sleep. With the Perseid meteor shower viewing party and the national photo contest still to come, it's shaping up to be a very eventful summer for this pair of insomniacs!
