Looking for similar songs/artists to Tsurugi (Tsukiko Amano)

Hello! I'm really bad at finding new songs, and I've been searching for similar stuff to this one song on and off for months now and not really finding anything I like. The song is Tsurugi by Tsukiko Amano. I'm not that knowledgeable with genres, but it was giving me a rock vibe. But looking through rock playlists on Spotify hasn't yielded much results. I'll add that I generally prefer lower female voices (as in it's my favorite, more than higher female voices or any male voices) which is probably part of why I was struggling to find much.

Do you guys have any recommendations for songs with a similar voice (and vibe)? Thank you in advance!
