Mysterious Boa Hancock File (Patreon)

I was making another backup copy of one of my old hard drives, and i found this mysterious video dated in 2017, it's just Boa Hancock with big... personalities dancing 😅, no audio and no more context, i guess i was trying to make something with MMD but i'm not sure exactly what 🤔, anyways here's the video for those who are curious.
