anime

There's a manga adaptation of Das Kapital. It's neat.

I'm gonna recommend a bunch of anime, since I'm less of a manga reader:

Rose of Versailles is the best depiction of revolution around, even if it handles something really poorly late in the show, but is about the bourgeois revolution in France 1789 instead of anything socialist - as the name says. The author hadn't gone back to being a lib yet back when it was written.

Fang of the Sun Dougram is the story of a guerrilla war of independence... with mechs, of course, because 1981.

The Irresponsible Captain Tylor is arguably pro-anarchist. E1 is the worst of the whole thing.

Patlabor is a mecha police slice of life/comedy made by a bunch of commies or commie-adjacent people in the late 80s. Patlabor 2 is basically a pondering of "1989-1991. what now?"

The Universal Century Gundam shows approach leftist themes, but Tomino's politics are kind of a mess.

Then there's left-friendly but ultimately still lib media like Interviews With Monster Girls (yes, really. It's somewhat horny, but it genuinely is actually good and has something to say about society, in spite of the fetishistic-sounding title), Ghibli movies, Hinamatsuri (for a big arc at least - inequality is a topic) and the like.

There was a famous leftist manga creator who's main Marxist works have never been translated into English https://hexbear.net/comment/3317686

Kamui Den, the first series published in Garo, can be considered his most important manga work. It is the story of Kamui, a ninja who leaves an organization that pursues him and clearly sees the true nature of the Edo period and the discrimination that existed in the feudal system. Shirato's works are primarily historical dramas that focus on ninja, present a historical record of Japan, and criticize oppression, discrimination, and exploitation.

I like to describe I'm in Love With The Villainess as 'Lesbian isekai with Marxist-Leninist Characteristics', as it has a revolution lead by a vanguard party in the first two light novels (which the manga has yet to get past the first two LNs). 'Part 2' of the story does get away from the same precise political themes a bit but it's still entertaining (and it'll probably be nice if/when the manga gets there).

I also read Koroshiya Yametai! (or: I wanna be fired!) recently. It's kiinda mid but it's lesbian and there's an interesting polemic about refugees and their role as cheap labor in the global north.

I can also recommend the classic Akira, which while it isn't explicitly leftist it portrays the military-industrial complex in fairly left wing fashion and also talks about some of the struggles of poverty.

I'll definetly give the ones that you've posted a look :)
