>>20643The late 1830s, Engels (the male self-insert) is a literal angel sent by god to save the world. Marx is a lazy, sharp-tongued tsundere with pink hair that is always fighting with her friend, the energetic tomboy (with brown/orange hair) Willich. Feuerbach, the cool-headed and reliable big sister/teacher character (black, long hair) often gives them tutelage and advice. Around episode 8 it is discovered that Feuerbach is literally the antichrist and that she is the leader of the shadowy cabal that has been conspiring against the group (mostly because she is jealous of Marx and wants Engels for herself). Engels defeats her in an intense final battle, after which he rejects Willich, who had proposed him around episode 6 after the beach trip, and proposes to Marx - she accepts, and the anime ends as they finally kiss on the ferry to London.
Yes, all the young hegelians besides Engels have to be women.
