I'm looking for Heart of Madness from Hokuto no Ken sung by a female

after scouring youtube myself I've only been able to find a live performance with meh sound quality, two women but in spanish, and a neco arc ai cover
my memory is hazy at best but I feel like years ago I heard a female cover of the song or at least part of it, and my inability to find it leads me to think it might've been an extra bit at the end of some other video or compilation and might not even be on youtube but perhaps on newgrounds, niconico, or some other website
