How does Ranma 1/2 end in the manga vs the anime?
The manga's final movement returns to where the curse began. Ranma and the cast travel to Jusenkyo for the Spring of Drowned Man, battle the Phoenix people who guard the springs' source, and fight over a cure that could lock Ranma male forever. The cure is lost in the chaos, and Ranma comes home still cursed, a choice that defines the ending: the story was never really about removing the curse.
The true finale is the wedding. Back in Nerima, Ranma and Akane's wedding is arranged, invaded by every fiancee, rival and grudge in the series, and postponed in the wreckage, but the final pages make the direction unmistakable. Takahashi closes on the couple running to school together, late as always, with the engagement no longer in doubt to anyone except, officially, themselves.
The 1989 anime has no equivalent. Nettohen ended in September 1992 because the production ended, not because the story did, and its final episodes are ordinary adventures. The OVAs adapted later manga arcs out of sequence but never attempted the Jusenkyo finale or the wedding, leaving screen Ranma permanently open ended in its classic form.
The difference shapes how the versions are valued. The manga is the only complete Ranma, which is why the Library treats the tankobon and the faithful English omnibus as the core texts, and the anime eras as beloved expansions. Fans waited decades hoping an adaptation would animate the ending; the MAPPA remake is the first production positioned to do it, if it runs long enough.
Spoiler care is part of this page's design: it describes the shape of the endings, not their final jokes, because Ranma's last volume earns its surprises. What can be said plainly is that Takahashi ended her series warmly and deliberately, and the ending is a major reason the manga outranks its adaptations in reader memory.
