The December 2020 issue of Ichijinsha’s Monthly Comic Rex magazine has published the final chapter of Eri Takenashi’s Rainbow and Black (Niji to Kuro) manga.
The story of the manga is described as:
College student Shirahoshi Kuroe feels like she’s living in black and white, and she longs for more excitement… until a small, rainbow, incredibly weird bird-thing brings color to her life. Now they live together. Is this creature just a pet, or is it more like a roommate? Penned by Eri Takenashi, a prolific Japanese artist best known for the manga (and anime) Kannagi, Kanpachi, and Take-Moon/Carnival Phantasm, this unique manga series is sure to move right into your heart.
Takenashi launched Rainbow and Black in Monthly Comic Rex in July 2018. Seven Seas Entertainment has licensed the series, and it will publish the first large trim edition volume on November 10, 2020.
