The below teaser in Square Enix's seinen manga magazine (yes, the video game developer also publishes manga in Japan) has revealed that there will be a spin-off of Mengo Yoshinari's Scum's Wish that will debut next month titled Kuzu no Honkai décor (Scum's Wish decor). The spinoff will focus on Hanabi.
The original manga ran for 8 volumes, beginning in September 2012 and concluding in March 2017. A Winter 2017 anime adaptation from Studio Lerche (Danganronpa: The Animation, Classroom of the Elite) covered more or less all 8 volumes in 12 episodes. The series was simulcast on Amazon's Anime Strike.
Yen Press published the manga in North America.
Hanabi and Mugi are bathed in envious gazers from all around as a beautiful couple with excellent moral conduct. But these two apparently perfect people in an apparently perfect relationship share a secret they can't tell anyone.
