What are your left wing manga/anime recommendations? I only got Ninpu Kamui Gaiden, because it is communist and ninjaic? You may shrug you shoulders, but a communist created all the ninja cliches, like a dude named Sasuke and the "Izuna Drop"! Unfortunately, the manga is from 1969, when the United States still had not erased all left-wing presence in Japan.
outside of uc gundam ibo also is pretty good. it's very focused on labor and class, and is kind of a great takedown of great man theory
also revolutionary girl utena is only truly leftist in its subtext (it's about the way patriarchy shapes things and how its systems abuse people but it's not hard to make the capitalism connection) but even without that it's about a bunch of queer youths navigating systems of oppression
