Susano Oh
With this manga, Nagai won the "Kodansha Manga Award" in the Shōnen category. The original serialization of Kodansha was suspended in 1981, but the success of the novels written by Yasutaka Nagai, prompted Kadokawa Shoten to request Go to resume his work on "Susano Oh". With this, the manga would be published for a period of ten years, from 1979 to 1989. Even so, the manga was left with an open ending for a possible next part.
