There actually was a short-lived ugly bastard vtuber created by infamous guro mangaka, Uziga Waita, who also had a vtube model for his original character, Death Panda.
Can anyone link me any primary sources about the Dungeon Seeker/Arifureta lawsuit? I've only seen people mention things on comments and forums; the best thing I could find was a mangadex comment paraphrasing a 2chan post.
