The February issue of Bessatsu Margaret also announced in January that Rainbow Days was approaching its climax.
This year’s second issue of Shueisha’s Bessatsu Margaret Sister Winter Fest magazine published a new one-shot by Minami Mizuno on Tuesday.
Mizuno announced on Twitter last month that her Rainbow Days manga has two chapters remaining.
The one-shot, titled “Koi o Shiranai Boku-tachi wa” (We Who Know Nothing Of Love), will tie into a new series that Mizuno will launch in the July issue of Bessatsu Margaret on June 13.
