Jujutsu Kaisen leans Marxist-Leninist, Chainsaw man actually delves deeper into Stalinism and some of Stalin's speeches and written works. There's even a part all about kulaks and the violence the bourgeois will enact to maintain their wealth and power, and goes into dialectical materialism. Makima, the main character's boss, is literally just authoritarian tankie-ism embodied in a person and as a woman to reflect that under Stalinism everyone had equal oppression opportunities. She literally also feeds Denji instead of paying him, reflecting the adage 'who doesn't work, doesn't eat' and because money is a capitalist social invention.
