I was bored on pornhub and stumbled upon a video that was literally just anime girls running.

What's the song? Sounds familiar. Pretty low quality sound output though.
I guess I'll bump this once.
EGOIST - Namae No Nai Kaibutsu.

I think it's a remix though. This song was the ending for Psycho-pass.
