The 19th chapter of Shiro Moriya’s Soloist in a Cage (Ori no Naka no Soloist) manga has announced that the manga’s 20th chapter will be the final chapter. The 20th chapter will debut on June 14, 2021.
The story of the manga is described as:
This is a prison where every single prisoner is housed, an inescapable cage, which has grown to the size of being considered a “city.” Born and raised in that bleak and snowy city, a young girl lives alone with her baby brother. What will be their fate? Their story of hope and struggle begins here.
Soloist in a Cage launched on Shueisha’s Shonen Jump+ website in September 2018, but went on hiatus in March 2019 due to Moriya’s sudden illness. The English version of the manga launched alongside Shueisha’s MANGA Plus English manga website in January 2019.
