That's just my theory for the song and the only reason I believe he is an Octo is on the assumption this song is gonna take place in Jakoku and afterall Gammon had to have gotten his black hair from somewhere so I don't think it is too wild of an assumption to believe he has some Jakoku blood running through him.

It could be about a war though as you say and a completely unrelated Gakupo.
