So I remember watching this music video which I think had the same sort of vibe as this one
https://www.youtube.com/watch?v=xplwZU3mKTA but a lot less energetic.
The video used footage from this anime where these cute lolis fought monsters on rollerblades (I think?), all I remember was the art style definitely didn't match because of how violent and gory it was. And I think the artsyle was somewhat similar to Tsukumizu's.
I'd like to find both the music video as well as the anime pls and thanks
