@Segoth said in Villainess Level 99 - Anime Discussion:

@pcj I never read the WN, just the LN here. Even if the WN has a darker ending than the LN, the LN has a darker ending than the anime. Again I’m only referring to vol. 1 which is what the anime covered.

I've not read the Manga, but from everything posted, it is obvious that the animators mostly took their queues from that, and that it was already significantly different from the LN.
