The Kamen Rider W series aired from September 2009 to August 2010 as the 11th Kamen Rider show in Japan’s Heisei era.
The manga is a sequel project for the 2009 Kamen Rider W (pronounced “double”) series. Riku Sanjō, a crucial writer for the original series, is in charge of the manga’s scripts.
It’s the beginning of a new battle for Kamen Rider W. The manga launched in Weekly Big Comic Spirits magazine in August 2017.
The manga also inspired a stage play adaptation titled Fūto Tantei The STAGE, which ran from December 2022 to January 2023 in Tokyo and Osaka.
