The hero of justice "Moonlight Mask", who appears dashingly on a motorcycle and slays the wicked, is back! In 1958, the TV drama was produced by Seikosha Productions, and it was an instant hit, and "Moonlight Mask Games" were played by children everywhere. It was such a monster program that "children disappeared from public bathhouses" during its airing time. Although "Moonlight Mask" has been adapted into manga by many mangaka, it was not until three months after the start of the TV program that the story was told in the form of a manga. The popularity of Jiro Kuwata's version, which was serialized in Kodansha's "Shonen Club" three months after the TV drama started, was overwhelming and contributed greatly to the increase in the magazine's circulation. The biggest reason for this was that Kuwata was good at what he did. The thrilling action scenes produced by Kuwata's sharp touch, was his forte. The expression transcended live-action and was a great hit with children, winning as much support as much as that of TV version. This book is a complete edition (9 volumes) that includes all chapters of Kuwata's version without omission. Some of the chapters are made by Kuwata's close friend and assistant, Koji Kusunoki, when Kuwata was too busy at that time. The complete edition of the book is a must-have for any fanatic.
