Shouyou Hinata, after losing to Kitagawa Daiichi Junior High's setter Tobio Kageyama in his first official volleyball match, transfers to Karasuno High, intent on finally having a proper volleyball team and getting his revenge on Kageyama. Upon arrival at Karasuno, however, Hinata finds out Kageyama has also gone to Karasuno. Initially at odds with each other, the two form an oddball combination and fight together with the other members of the volleyball club. Karasuno reunites with a former rival school, Nekoma High, in a practice match and reignites their school rivalry.
Masaru, a 23-year-old who has a passive attitude toward life in general, professes himself as a “genius odd-job-man” but is screwing up all of the time. He is freeloading off his girlfriend Kiriko, who works as a tattoo artist. One day, he is offered to do a rather eccentric job from an otaku-looking public employee named Nirasawa, who claims that Masaru’s voice is necessary in activating a giant robot named Land Zeppelin. He goes on straight-faced that the Earth is about to be attacked by Saturnians, and the robot is necessary in the fight against them. At first, Masaru ignores this far-fetched story, but one day he is framed in a dangerous job he takes on together with his friend Kou, and is driven into a tight squeeze. What will happen to Masaru? Does this robot Land Zeppelin really exist?
