[Desperate] Looking for an old Mugen music video

Hey everyone,

in the early 2000s a friend and I got a Mugen fighter and within the files was a really cool music video. I can't find it, and I've been looking for weeks. So I'll try here, maybe someone remembers.

What I think I remember:

1. It wasn't the intro, it was in the files of the Mugen
2. It featured C17 and C18 in the Future Trunks timeline and you saw them walking to, and I think killing, Goku in his house.
3. It also featured Vegeta standing in the rain
4. I think the video was in Japanese and by a female singer
5. The length was about 1m30s or so, if I had to guess.

Please tell me I'm not tripping :(
