Episode 1/Ubel blatt review from someone who read the manga.

@BanryuTV The censoring isn't even the main problem, they just skipped an entire volume of world building and character introduction. Of course anime-only viewers have no idea what's going on.

Since I've dropped the anime after ep2 - did they by now explain that Keinzell was the former hero Ascheriit from 20 years ago? Did they explain how he almost died because the other 7 heroes betrayed him and his 3 comrades and barely survived due to eating an elf (or being eaten by one, he doesn't remember)? That it took him 10 years to regain and stabilize a human-like body and that his current half-elf body is incredibly unstable, so he can't even use the same strength and powers he formerly had as Ascheriit? He might be a sword master but inhabits a defect body that's only at 100% when the moon shines brightly, that's why we seem him strugle even against minor enemies early in the story.

^ That information is entirely from volume 0, which they didn't adapt. I hope it's more clear now why this anitme is garbage.
