Are we actually back? Did the artist conclude their Hiatus?
No, these chapters were the last* before the series went on hiatus in December 2022. Just hadn't been translated until now.
And this was the last one before the story was thrown into hiatus purgatory in 2022.
*Actually, there is one more chapter, Episode EX from the volume.
@NamekazeMinato, ye gonna do that one?

Except… after 6 chapters of Paladin-chan (only 3 of which have been translated;
@NamekazeMinato, eh
