Reversal Jewel Arc

The  is the 55th story arc covered in the Ranma ½ manga, spanning four chapters. This arc was included in volume 22 of the  and volume 21 of the Viz Media tankōbon.

Plot Summary
Cologne lets Shampoo choose a piece of antique jewelry from her collection. Shampoo chooses a brooch from a box. The brooch can control the wearer's emotion depending on how it is placed. If it is right side up, it amplifies the love one has even more, whereas if it is upside down then any love the person has for one turns to hate. She puts it on upside down without knowing the effects and begins hating Ranma, running him over with her bike and ignoring him every other time. Ranma then boldly claims that he will make her love him again. Ranma attempts various tactics he read from a magazine, but nothing seems to work.

Suddenly he is greeted by Cologne, who tells him that the only way for Shampoo to love him again is to tell her that he loves him. He accepts this idea, and after getting Ukyo to tell him that she loves him, is confident that it will work. He proceeds to the Cat Café, where Cologne and Shampoo prepare. Once he gets there, he begins to get nervous and stall. When he finally comes to saying the words, it is overshadowed when Akane says "I love you" to him first, thanks in part to Mousse placing the brooch in an upright position. Ranma is glad to have won his love battle but ends up in hospital when he remarks on Akane's weight.
