I want to use my usual username for it since I'm so used to being called by it but I don't want to risk oshi knowing I stream and I want to be able to simp in her chat without the chance of someone who watches me noticing.
My general recommendation would be to use something that isn't used often enough to get you overwritten on a google search.
For example Sherlock Holmes is public domain but if you search that you'll always get Holmes the character and never a vtuber.
Even Oliver Evans mainly gives the real guy instead of the Nijisanji Liver.
Mixing the names of two characters you like might work.
Like Edogawa Lupin.
Or maybe Remilia Knowledge if you're a girl.
