>>454805vtubers are characters, played and acted out by the person controlling them
vtubers are like puppets, whereas avatars are like masks
the key difference here is that vtubers are a little more than just characters. They're characters that technically exist *here*, in the real world.
They make the videos on YouTube, they edit, they livestream, etc. There's a large degree of separation between the vtuber and the real person behind them
Annoying Orange is a web series/TV show. Orange doesn't record episodes, Orange doesn't stream, it's all Dane Boe (he even still has those original episodes still up!)
Likewise Grade A doesn't even have a "character" it's just him with a funny voice and a big chin avatar.
