Chapter 22
Extra 19.1
This extra hasn't been compiled in volume 4, or volume 5 for that matter. We're only labelling it as belonging to v4 because it was released between chapter 19 and 20. It's possible that it will be compiled in a future volume and need relabelling.
There's a download option in the reader, too.
We'd like manga translators to resume or start projects. Please apply!
