‘한 때’ 고교 배구의 명문이었던 카라스노 고교에 입학하게 된 의욕 충만한 스파이커 ‘히나타’. 우연히 중학 시절 시합에서 만났던 천재 세터 ‘카게야마’를 같은 학교 배구부에서 만나고, 라이벌 구도를 형성하지만 점차 호흡을 맞추게 된다. 카라스노 고교 배구부는 예전의 명성을 찾기 위해 점차 팀을 꾸리게 되고 영원한 라이벌 네코마 고교와의 본격적인 첫 공식 연습 경기를 가지게 되는데… 최강이 되기 위한 불꽃 같은 승부가 시작된다!
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?
