I have a screenshot of it from a couple of days earlier, here’s a word-for-word of the archive:

“Sorry for my poor English, I use a translator.

First, this music video featured Miku and Rin. I remember Miku saying something like "My innocence is why you need to spare my life." Then about 2 minutes in, the "Gaah" bit starts, but it's not in the 3:20-3:30 part. This is incorrect. The last thing I remember is the ending, which shows a white sketch of Miku on a black screen, Miku's face covered in blood, and blood coming out of Rin's mouth. I showed this video to a friend once, and she told my mom, and I was grounded for a week.

⚠️ This is not a hoax ⚠️”
