Ranma ½

Ranma ½ has a comedic formula and a sex-changing main character who often willfully transforms into a girl to advance his goals.

On a training journey in the Bayankala Mountain Range in the Qinghai Province of China, Ranma Saotome and his father Genma fell into the cursed springs at Jusenkyo (呪泉郷).

Soun Tendo is a fellow practitioner of Musabetsu Kakutō Ryū (無差別格闘流) or "Anything-Goes School" of martial arts and owner of a dojo.

Soun has three teenage daughters: the polite and easygoing Kasumi, the greedy and indifferent Nabiki and the short-tempered, martial arts practicing Akane.

Both Ranma and Akane refuse the engagement initially, having not been consulted on the decision, but the fathers are insistent and they are generally treated as betrothed and end up helping or saving each other on some occasions.

Ranma goes to school with Akane at Furinkan High School (風林館高校, Fūrinkan Kōkō), where he meets his recurring opponent Tatewaki Kuno, the conceited kendo team captain who aggressively pursues Akane, but also falls in love with Ranma's female form without ever discovering his curse (despite most other characters eventually knowing it).

Another rival is the nearsighted Mousse, who also fell into a cursed spring and becomes a duck when he gets wet, and finally, there is Genma and Soun's impish grand master, Happosai, who spends his time stealing the underwear of schoolgirls.

Ranma's prospective paramours include the martial arts rhythmic gymnastics champion (and Tatewaki's sister) Kodachi Kuno, and his second fiancée and childhood friend Ukyo Kuonji the okonomiyaki vendor, along with the Chinese Amazon Shampoo, supported by her great-grandmother Cologne.

As the series progresses, the school becomes more eccentric with the return of the demented, Hawaii-obsessed Principal Kuno and the placement of the power-leeching alternating child/adult Hinako Ninomiya as Ranma's English teacher.

Some of the places frequently seen in the series are modeled after actual locations in Nerima, Tokyo (both the home of Takahashi and the setting of Ranma ½).

[8] In a 1990 interview with Amazing Heroes, Takahashi stated that she had four assistants that draw the backgrounds, panel lines and tone, while she creates the story and layout, and pencils and inks the characters.

In 1992, she explained her process as beginning with laying out the chapter in the evening so as to finish it by dawn, and resting for a day before calling her assistants.

In 1993, an Animerica interviewer talking with Takahashi asked her if she intended the sex-changing theme "as an effort to enlighten a male-dominated society."

Takahashi said that she does not think in terms of societal agendas and that she created the Ranma ½ concept from simply wanting "a simple, fun idea".

She added that she, as a woman and while recalling what manga she liked to read as a child, felt that "humans turning into animals might also be fun and märchenhaft... you know, like a fairy tale.

From August 1987 until March 1996, the manga was published on a near weekly basis with the occasional colored page to spruce up the usually black and white stories.

North American publisher Viz Media originally released Ranma ½ in a monthly comic book format that contained two chapters each from 1992 to 2003, and had the images "flipped" to read left-to-right, causing the art to be mirrored.

At Anime Expo on July 7, 2013, Viz Media announced re-release of the manga in a format that combines two individual volumes into a single large one, and restores the original right-to-left reading order (a first in North America for this series).

[24] An anime television series was created by Studio Deen and aired weekly between April 15, 1989, and September 16, 1989, on Fuji TV for 18 episodes, before being canceled due to low ratings.

The series was then reworked by most of the same staff, retitled Ranma ½ Nettōhen (らんま ⁠1/2⁠ 熱闘編) and launched in a different time slot, running for 143 episodes from October 20, 1989, to September 25, 1992.

The anime stays true to the original manga but does differ by keeping Ranma's gender transformation a secret from the high school students, at least throughout most of its length.

[26] In September 2020, Toonami co-creator Jason DeMarco revealed that he had previously tried to get Ranma ½ aired on the American TV programming block, but "it's something we never were able to figure out, because, frankly, there's too much nudity.

Incense of Deep Sleep" manga story from volume 34, it was shown on odd numbered days at the exhibition in Tokyo from July 30 to August 11, 2008.

The first season aired from October 6 to December 22, 2024, on Nippon TV and its affiliates,[a] with Netflix licensing it for streaming worldwide weekly after the Japanese broadcast.

The special stars Yui Aragaki as Akane, with Kento Kaku and Natsuna Watanabe playing male and female Ranma respectively.

"[50] Reviewing the final volume of the manga, Anime News Network remarked that "Every dimension of Rumiko Takahashi's storytelling skills come into play here: comedy, romance and introspection, and of course, high-flying fantasy martial-arts action.

"[75] However, they felt some of the action scenes were hard to follow and noted that the mirroring to left-to-right format caused errors with the art.

[78][79] Mike Toole of Anime News Network included Big Trouble in Nekronon, China at number 83 on The Other 100 Best Anime Movies of All Time, a list of "lesser-known, lesser-loved classics," calling it "a solid action-comedy and a good, well-rounded example of the appeal of Ranma ½"[80] Hiroshi Aro admitted that he created Futaba-kun Change!

[84] Matt Bozon, creator of the Shantae video game series, cited Ranma ½ as a big influence on his work.
