>>22190222She's definitely over 25, called anyone under 25 babies. Likes a lot of old shit like Ami does. But she also almost sold feet pics to someone online when she was underage, so she can't be too old. She's really into internet shit and I'm guessing heavily into Tumblr type communities from the shit she seems to be into, so she probably heard about vtubers the same way we all did.
