As revealed in the February issue of Shueisha’s Bessatsu Margaret magazine, Nijiiro Days (Rainbow Days) manga is approaching its climax, presaging its end. The creator, Minami Mizuno, confirmed the rumors on her Twitter account and specifically mentioned that only two chapters remain. If there are no breaks, the manga is expected to end on March 13.

At the same time, this year's second issue of Shueisha's Bessatsu Margaret Sister Winter Fest magazine published a new one-shot manga by Mizuno titled Koi o Shiranai Boku-tachi wa (We Who Know Nothing Of Love). This will become the new manga series by Minami Mizuno after Nijiiro Days and it will be launched on June 13 in the July issue of Bessatsu Margaret.

Mizuno launched Nijiiro Days on February 2012. On January 2016, the anime series premiered, while the story has also inspired a drama CD.
