miwa did a collaboration with SUGIZO (lead guitarist of Luna Sea) and I didn't know about this info before, but the song is an ending theme to Mobile Suit Gundam THE ORIGIN: Zenya Akai Suisei. It's on
Spotify as well.
Never know about this before but, I like the song! I hope she keeps going with good release in the future.
She will also release another new single Storyteller/Teenage Dream on December 25h. One of them is the opening song for Boruto.
Teenage Dream is also on Spotify now, but... uh, meh.
