The manga is serialized on the Gene Pixiv site and has three volumes out so far.
The TV anime series was directed by Owl Todoroki with Shin Okashima handling the scripts.
The fall 2018 anime adaptation of the web manga series Gaikotsu Shotenin Honda-san from Honda looks like it may not have been enough to save the manga that inspired it.
The property is the first professional work from creator Honda and the manga is distributed in print form by Media Factory.
