The anime series of Ranma ½ does not have a definitive ending; it simply stops after 161 episodes with the status quo largely unchanged. Ranma is not cured, and his relationship with Akane, while progressed, is not officially resolved. The final arcs adapted involve Ranma's mother, Nodoka Saotome, visiting the Tendo Dojo, forcing Ranma and Genma to hide their curses from her due to a vow Genma made to raise Ranma as a 'man among men' or commit seppuku.
The manga, however, continues for much longer and has a conclusive final arc. The main characters travel to the Jusenkyo springs in China for a final confrontation with a powerful villain named Saffron, who controls the springs' water flow. During the battle, Akane is critically injured and seemingly dies after saving Ranma. Desperate, Ranma manages to defeat Saffron and restore the flow of water, reviving her. The Jusenkyo guide offers Ranma a container of water from the 'Spring of Drowned Man,' the long-sought-after cure. Back in Japan, everyone prepares for Ranma and Akane's wedding. Just as they are about to exchange vows, Happosai appears with the container of cure water, thinking it's sake, and drinks it, causing chaos that disrupts the wedding. The various rivals and fiancées crash the ceremony, turning it into an all-out brawl. In the end, the wedding is postponed, and Ranma never gets cured. The final panel shows Ranma and Akane running to school together, bickering as usual, implying that while their feelings are clear, their chaotic life will continue.
