Insider here. To me, Pomu is an arrogant succubi. She has had her first taste of power after being an OL and a failed indie vtuber for so long. She is quick to anger with her audience (like Ame) and is openly disgusted by them (also like Ame). She references zoomer memes to keep her viewers on the hook but she knows that won’t keep them interested forever. She is trying to to become the most successful vtuber in history by using her position as a white female super otaku in an industry dominated by fish face Japanese women to climb the ranks of Nijisanji and the broader vtubing industry and eventually push vtubing into the mainstream. She has already bent the knee to the Chinese for their power and the sponsorships are coming soon.
