>>39379230I can tell you what I think about them: The japanese chat is neccessary for Koro as feedback. English comments are welcome in theory, but can become a nuisance if they are too numerous.
Also, VTubing has a lot of rules and conventions that english speakers are usually not aware of.
As long as you don't stick out too much, don't drown out the japanese chat, and don't bring in politics / talk about unrelated stuff, she'll probably be happy to have you.
