コミックフラッパー
Out of requests, Terasawa announced in February 2016 he would create a new saga for "Cobra". He aims to deal with the unsolved plot of the strange resemblance of two female characters—Dominique and Secret. More than three years later, in November 2019, "Comic Flapper" magazine's official Twitter account announced the release of "Cobra: Over the Rainbow". A sequel to the original manga, it started to be released digitally on November 19 through Kadokawa Corporation's "Comic Walker" and Niconico Manga websites under the "Comic Hu" label.
