If we are talking about how Coco affected Hololive these are all the negatives:
1. She gets brought up all the fucking time by annoying EN fans
2. If there is a dragon, they mention Coco
3. If there are meme reviews, they mention Coco
4. If an EN member like Mori, Kiara or Ame does something innovative they praise Coco.
5. Kanata had rooted relationships surrounding Coco. She has successfully gotten free from it thankfully.
6. Coco is more remembered by JP fans than you might think, her appearance is more likely to appear than an EN or ID member in Soul Calibur (Hosted by Miko or Pekora)
