Mazinger Z Interval Peace is a manga spin-off of the 2017 anime movie. It debuted in the June issue of Monthly Young Magazine. The manga's scenario is drawn by Takahiro Ozawa while artwork is drawn by Kaoru Osada. Compared to some of its contemporaries, the series is a 'youthful group drama', following the pilots conflicts rather than the robots.
The manga takes place in a world where the use of Super Robots is questioned. Koji is a former pilot with his companions faced with both personal and outer conflicts. They were once heroes but peace was achieved, bringing their robot's use into question. Can this peace even last and can it even lead to true peace...?
