Synopsis
A tabletop world like a tray. There, the mechanical sun illuminates the world. The gliding sun operated by the public organization "Taiyo Kikaisha" was called "128 type". Type 38 rifle engineer Sabouraud is a habitual criminal who is late and absent without notice because he has been working for four years since joining the company. He was Saburo who couldn't get angry, but the only person he wasn't good at was Daigo, the chief of staff. One day, Sabouraud witnesses a secret meeting between Daigo and the "Hishii Institute," which is developing a launch-type sun. If the launch-type sun is operated, the engineers will be disqualified. Saburo's disgust and distrust of Daigo are intertwined, and he drives Daigo into his home.
