Horsegirl actually growing on me. She just dropped a video debunking every rrat about this situation, including one where she say moruru graduation stream was just a zatsu stream and not a totsumachi one. While finding clips from the archives. Tl;dr:
there isn't any concrete proof moruru was bullied by another talent.
Her viewers didn't watch a single second off the video and just comment by the title though.... And even random ass rrat about polka...

. Idk why she always went for research and not acknowledging rrats in her content but her audience are like this.
