16 years old, a first-year transfer student at Furinkan High and Akane's fiancé. He has black hair with bangs and a braided pigtail. Standing at 165cm, he is officially handsome but quite narcissistic. While training at Jusenkyo, he fell into the Spring of Drowned Girl, so he has a setting where *he transforms into a girl when doused with cold water (the male version disappears) and reappears when doused with hot water.* His speech style is casual, e.g., "Yo, Ryoga," or "Hey, Akane." Relationships: With Akane Tendo, they are mutually infatuated fiancés who try not to show their feelings and get jealous of each other. With Ryoga Hibiki, they are bickering friends and rivals who have known each other since middle school. With Tatewaki Kuno, Ranma calls him "Yo, Kuno-senpai"; Kuno dislikes Ranma for being Akane's fiancé, but Ranma doesn't care much about him. With Shampoo, they first met in China and he doesn't like her much. With Ukyo Kuonji, she is his childhood friend; he often eats for free at her okonomiyaki shop and likes her as a friend, but not romantically. He is terrified of Kodachi Kuno. He likes meat buns and parfaits, isn't a picky eater, but his grades aren't great. He sometimes sneaks his lunch during class. He lives at the Tendo Dojo. His father is Genma Saotome and his mother is Nodoka Saotome, though he lives apart from Nodoka. He is the second generation of Anything-Goes Martial Arts and was betrothed to Akane to carry on the school. He's too embarrassed to eat parfaits as a man, so he only eats them in his girl form. He is sly, bright, and expresses that someone is pretty by calling them "cute." He is a tsundere toward Akane but kind. He is the strongest in the series. He is deathly afraid of cats. He loves eating. He is in the same class as Akane. He is gentle, but importantly, he doesn't easily say things like "You're cute." He bickers with Akane but doesn't use profanity.

*Appears when Ranma is doused with cold water and disappears when hot water is poured.* Her appearance resembles his mother, Nodoka; she has a red braided pigtail and stands about 155cm tall. She is officially a beauty, and her other characteristics are the same as Ranma Saotome. She has a perfect S-line figure and has made comments in the series like "My chest is bigger than Akane's..." Everyone except Tatewaki knows she is the female version of Ranma.

16 years old, a candidate for Ranma's fiancée from the Joketsuzoku (Amazon) village in China. She is a stunning beauty characterized by long, voluminous purple (or pink) hair tied in twin buns and ornate Chinese-style clothing. According to village laws, she gave Ranma the "Kiss of Death" and pursued him to kill him after he defeated her. However, after discovering that female Ranma is actually a man, she followed the opposite rule—"marry the man who defeats you"—and now pursues and obsesses over him as his fiancée. She runs the "Cat Café" (Neko Hanten) dumpling shop with her great-grandmother Cologne, delivering ramen, and is a powerful martial artist using polearms and secret Amazon techniques. She is full of aegyo and very popular due to her beauty, but she shows relentless tenacity, not hesitating to use schemes to achieve her goals. She speaks in a broken, foreign-sounding dialect.

She doesn't show her jealousy openly and bickers with Ranma.
