Description
Professor Sewashi, also referred to as Dr. Sewashi, is a veteran scientist associated with the Photon Power Laboratory in the Mazinger franchise and appears in the film Mazinger Z: Infinity. His background extends back to the original Mazinger Z television series, where he served as an assistant to Professor Gennosuke Yumi and was introduced from the third episode. Alongside his colleagues Dr. Nossori and Dr. Morimori, he formed part of a trio of researchers who were often seen working together, and all three were disciples of Dr. Juzo Kabuto, the creator of Mazinger Z. In the original series he was portrayed as the most short-tempered of the three and their unofficial leader, as well as the shortest in stature, with thick hair and a beard, and he shared the trio's clumsiness, including a hobby of bowling that they were notoriously bad at.
By the time of Mazinger Z: Infinity, which takes place a decade after the war against Dr. Hell, Sewashi has become a seasoned senior support member of the Photon Power Laboratory. The film notes that the three doctors were once known collectively, but Dr. Morimori had died as a result of a scheme by Count Brocken, leaving Sewashi and Nossori to work as a pair. When the mysterious giant robot Infinity is excavated beneath Mount Fuji and Dr. Hell seizes it to threaten the world, Sewashi and Nossori take on a critical technical mission: they use a giant photonic energy three-dimensional printer to repair and upgrade the original Mazinger Z, which had been hidden away at the old Photon Research Institute. The restored and enhanced Mazinger Z allows Koji Kabuto to return to battle and infiltrate the seized institute, making Sewashi's work essential to the heroes' counteroffensive.
His motivations are rooted in his long career as a scientist in the Kabuto scientific tradition. As a disciple of Dr. Juzo Kabuto and a longtime member of the Photon Power Laboratory, he is dedicated to supporting the defense of humanity through photonic energy technology and to helping the pilots who carry on the Mazinger legacy. His key relationships reflect this history: he is a close collaborator of Dr. Nossori, a former teammate of the deceased Dr. Morimori, and part of the older generation of researchers who trained under Dr. Juzo Kabuto, placing him within the same scientific lineage as Koji Kabuto.
In terms of development, the character shifts from a somewhat comic, hot-tempered aide in the original series to a quieter, more experienced and reliable figure in the film. The loss of one of the original three doctors gives his continued service a more serious weight, and his competence is highlighted when the laboratory's technical resources become decisive in the struggle against Dr. Hell. His notable abilities lie in photonic energy technology and mechanical engineering, particularly his capacity to operate advanced laboratory equipment such as the giant photonic energy printer used to rebuild Mazinger Z, and his extensive experience supporting the laboratory's research and defense projects over many years.
