It's not HoloEN 5 but I wouldn't be surprised if she's been doing consultation work where she can offer insights on home 3d tech, western audience tastes, 3d event production with a more casual or less music-focused theme and how to weather controversies and cancellation attempts in western social media. All topics that Cover might be interested in, going forward with their EN development.
I remember she mentioned a while ago, she was invited by some now-defunct corpo (Idol-EN maybe?) to give a presentation for their newly debuting vtubers. That was mostly bullshit optics from a bullshit company BUT I always thought that behind her goofy class clown persona, she was someone who thought very seriously about working as a vtuber and treating this like a professional career.
