Gonna Help raise the dead here, I still have hope for this series. My favorite, done mulitple re-reads of the WN, and the author has started writing more of it again!

Apparently there's an upcoming manga adaptation of Death Flags, for Mangabox. https://twitter.com/orefura/status/1224007462623182851 The original webnovel is still ongoing, but the author posts new chapters at a very slow rate ever since 2017, with hiatuses of 1-5 months between chapters. Likely Vol 5 hasn't come out because there isn't enough material for publication.

Please license this light novel. The manga is really good, but it is inconsistent with releases. I really want to read ALL of the differences between the Web Novel version and the Light Novel version (because I can't read or understand Japanese). I would definitely buy every volume of the light novel if it ever gets licensed.
