Please help find an anime from my childhood
Back in the mid-90s, I got a VHS with a movie on it. After the movie ended, there was a short 5-minute anime fragment. It was a brutal and bloody scene where a main (or important secondary) character was dying or getting infected by some kind of virus (it was like 30 years ago, so I don't remember exactly). People were screaming, and one word was repeated constantly: "Owaru! Owaru!" I'm not sure if it was the dying character's name or the Japanese word for "it's over / ending," but either way, it made the scene even more disturbing.
What I'm 1000% sure about is the credits. It wasn't just text on a black screen, it was stylized animation, serving like a music video. The song was heavy, industrial/metal. The visual showed a character on a motorcycle, and instead of hands (or holding weapons), they had scythe blades.
