Wait wiat why is this marked as complete??

Maybe the future chapters scarred/ triggered them. I wouldn't blame them for dropping it if that's the case. Hopefully, someone ( or maybe the current translator) can finish it just so we can read the rest of the story and finally understand what is happening.

This was published back in 2017 in japan, doesnt seem likely there was a continuation, likeliness the volume ended with 4 chapters is possible.
