@TrueAether It's Monna not Lynn. Monna has brown short hair and Lynn has long black hair. Monna's hair would be visible in the screenshot in the art, but it's not. It's brown short hair right at the top of the screenshot.
Here's a screenshot of the scene I grabbed from a video. Notice it's Monna standing to the left of Ellen.
Image is tagged Vocaloid on Pixiv but I'm not sure if this is a reference to a real-life death or a Vocaloid song. First impression is that this is wowaka but the upload date would be off by two months.
