>>14151943Yes, but some are worse flops than others. Normally it's not really a big deal for most seiyuu. For example, Ayaneru has been a part of some bad flops, but she's voiced enough popular characters in popular anime, to the point where she will always score in the top of most seiyuu rankings. The flops don't really detract from a seiyuu's popularity, but it's the amount of popular roles that really boost them.
In Nozomin's case, she has only ever voiced minor background characters. her biggest role was just a supporting character in Granbelm. She hasn't landed a single popular role in a single popular anime. Normally, this would pretty much be the end for any seiyuu who's been in the industry for over 5 years, but Nozomi has gotten a huge following through her work as Kizuna Ai. If she decided to jump ship, she could go back to being a seiyuu and she would have a good chance at landing big roles. I'm sure plenty of agencies would be happy to hire the personality behind Kizuna Ai, and plenty of otaku would love to see her live.
The Kizuna Ai project was really a huge opportunity for her to advance her career. She's already reached her peak as a vtuber, so now is her best chance to really move on. If she stays on youtube as a waning internet personality, people will eventually lose interest in her all together.
