The 16th compiled book volume of Minami Mizuno’s Rainbow Days manga revealed on Tuesday that the one book volume of the upcoming Rainbow Days side-story manga is slated for 2018.
Rainbow Days centers on a group of four male high school students who are close friends: Natsuki, Tomoya, Keiichi, and Tsuyoshi.
Mizuno launched the manga in the February 2012 issue of Bessatsu Margaret, and ended it on March 13.
The manga inspired a drama CD that Shueisha bundled with a limited edition of the seventh volume in October 2014.
