A Sadist's Whisper (溺死) (feat. Ohaikou & more) - Project DIVA: Deep Blue

In an alternative universe where Hatsune Miku lost most of her popularity after the release of Triple Baka, Miku enters a state of depression, making rashful actions against herself as a way of coping. Shortly after, she decides to go after those who stole her voice and used it for their own popularity. The person she first goes after is Yowane Haku, who she grew up with as a child, being disgusted that she ever trusted Haku, thinking all she did was selfish and egotistical, that she never cared.
