hello , I've been struggling to find a song about japanese navy from some anime I think your profile picture belongs to that anime aswell I might remember wrong but Ithink actually you posted that song aswell now I cannot find it, can you somehow help me ? song's title was something related to sacrifice.
I believe his profile picture is from the 1971 movie, "Animentary: Ketsudan", meaning "Decision". He has translated the theme songs already and has uploaded it to his channel.
