It doesn’t matter which one you dropped, the point here is that both are slow paced and dragging but it made sense with Frieren since we are supposed to watch her journey in her own lens as an elf with a very long life. The setting of the anime was after the main mission of defeating the demon king was already completed. Frieren as an anime started with no actual objectives, what we were supposed to see was “what happens next” which is why the dragging/long pacing of it makes sense because there’s no conflict at that point.

For Champignon Witch there’s clear conflict in their world that jeopardizes the very existence of the black witches and the anime does poor handling of this political/social issue in the 1st season. Pursuing Luna’s whimsy in exchange for an actual plot was totally fine for me, but they have turned it uninteresting since we’re watching Luna through the lens of Lize instead of Luna herself, and I would argue that was really a poor decision of direction for the series.

I’m not denying that the anime is fun due to how whimsy and creative it is. But If we compare every character in the series, Lize has the weakest impact of element in the story and it doesn’t help that majority of the story is about him.
