She's being fired because she knows the truth. 95% of Hololive Vtubers are pedos/groomers. All the girls in JP fuck little boys every day and she found out after she received a text message from Marine by accident. She was going to tell the police but Yaguoo (I don't know how to spell his name) stopped her and fired her on the spot. He then used his power and money to convince her to never talk about it and graduate her. That's what's really going on.
