Ranma ½

On a training journey in the Bayankala Mountain Range in the Qinghai Province of China, Ranma Saotome and his father Genma fall into the cursed springs at Jusenkyo (呪泉郷). The cursed spring causes any afflicted to assume the physical form of whatever drowned there hundreds or thousands of years ago whenever they come into contact with cold water, which reverts on contact with hot water but resumes with exposure to cold water. Genma fell into the spring of a drowned panda while Ranma fell into the spring of a drowned girl.

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. Genma and Soun agreed years ago that their children would marry and carry on the Tendo Dojo. Soun has three teenaged daughters: the polite and easygoing Kasumi, the greedy and indifferent Nabiki and the short-tempered, martial arts practicing Akane. Akane, who is Ranma's age, is appointed for bridal duty by her sisters with the reasoning that they are the older sisters and can dump the duty on her, and that they all dislike the arranged engagement and think Akane's dislike of men is the right way to express it to the fathers. At the appointed time they are surprised when a panda comes in and puts a girl in front of their father. The Tendo girls all laugh. It takes several more pages for the situation to be explained to Soun Tendo and his daughters. 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. They are frequently found in each other's company and are constantly arguing in their trademark awkward love-hate manner that is a franchise focus.

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). Nerima serves as a backdrop for more martial arts mayhem with the introduction of Ranma's regular rivals, such as the eternally lost Ryoga Hibiki who traveled halfway across Japan getting from the front of his house to the back, where Ranma spent three days waiting for him. Ryoga, seeking revenge on Ranma, followed him to Jusenkyo where he ultimately fell into the Spring of the Drowned Piglet. Now when splashed with cold water he takes the form of a little black pig. Not knowing this, Akane takes the piglet as a pet and names it P-chan, but Ranma knows and hates him for keeping this secret and taking advantage of the situation. 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. Ranma's indecision in choosing his true love causes chaos in his romantic and school life.

Rumiko Takahashi stated that Ranma ½ was conceived to be a martial arts manga that connects all aspects of everyday life to martial arts.[4] Because her previous series had female protagonists, the author decided that she wanted a male this time. However, she was worried about writing a male main character, and therefore decided to make him half-female.[5] Before deciding on water for initiating his changes, she considered Ranma changing every time he was punched. It was after deciding this that she felt Jusenkyo had to be set in China, as it is the only place that could have such mysterious springs.[6] She drew inspiration for Ranma ½ from a variety of real-world objects. 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).[7]

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.[8] All her assistants are female; Takahashi stated that "I don't use male assistants so that the girls will work more seriously if they aren't worried about boys." 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. They finish it in two or three nights, usually utilizing five days for a chapter.[5]

Takahashi purposefully aimed the series to be popular with women and children. 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."[9] In 2013, she revealed that at the start of Ranma her editor told her to make it more dramatic, but she felt that was something she could not do. However, she admitted that drama did start to appear at the end. She also sat in on the voice actor auditions for the anime, where she insisted that male and female Ranma be voiced by different actors whose gender corresponded to that of the part.[10]

By November 2006, it was reported that Ranma ½ had sold over 49 million manga volumes in Japan.[49] Shogakukan has printed 53 million copies as of November 2011.[50] And by April 2021 it had 55 million copies in circulation.[51]

The Ranma ½ anime was ranked number 17 on Anime Insider's 2001 list of the Top 50 Anime,[52] although the list was limited to series that were released in North America. It ranked 36th on TV Asahi's 2006 list of Japan's 100 favorite animated TV series, which is based on an online poll of the Japanese people,[53] up from the previous year's list where it ranked 45th.[54] In November 2006, the New York Comic Con announced that it would host the first-ever American Anime Awards. Fans had the chance to vote for their favorite anime online during the month of January 2007. Only the five nominees receiving the most votes for each category were announced on February 5. Among the 12 different categories, Ranma ½ was voted into the "Best Comedy Anime" category, and the Ranma ½ OVAs were voted into the "Best Short Series" category.[55] A 2019 NHK poll of 210,061 people saw Ranma ½ and Ranma ½ Nettōhen named Takahashi's second best-animated work. Shampoo and Ranma were voted fourth and fifth place respectively in her characters category.[56]

Although Lum from Takahashi's first series Urusei Yatsura is often cited as the first tsundere character in anime and manga, Theron Martin of Anime News Network stated that Ranma ½'s Akane Tendo is closer to how they would later typically be portrayed in the 2000s. He also suggested that one could argue Ranma is an early example of a harem or reverse harem series, due to the main character attracting suitors in both genders.[57] The series's publication in North America proved highly successful as well, being many Americans' first introduction to manga and its anime adaptation one of the first Japanese animation shows to achieve popularity in the US.[58][59] In an overview of the series, Jason Thompson called Ranma ½ "the direct ancestor of all comedy-action manga, like Sumomomo Momomo and History's Strongest Disciple Kenichi", although noted that it was not the first, but only spanned the period when manga and anime sales were at their height.[35] Relating it to Takahashi's other works, he summed the series up as "At the start, the fighting is minimal and it's almost a semi-serious relationship comedy, like Maison Ikkoku; then it turns completely ridiculous; and by the climax, when Ranma fights the evil bird-people of Phoenix Mountain in an excessively long and un-funny fight scene, it's like a warmup for Inuyasha."[35] 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."[60] 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.[60]

In their review of Viz Media's season five DVD box set, Anime News Network praised the Japanese cast's performance and the animation, but criticized the English version's slight script changes and minor voice actors while praising its main cast. They also remarked that while Ranma ½ is a classic, after a hundred episodes, the same jokes are just not funny anymore.[61] THEM Anime Reviews' Raphael See called the television series and the OVAs "one of the funniest things [he's] ever seen, anime or otherwise" and also praised the English dub as some of the best.[62] However, he was much more critical of the first two films particularly for both using the same damsel in distress plot.[63][64] 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"[65]

Hiroshi Aro admitted that he created Futaba-kun Change! based on Ranma ½.[66] Western comic book artists who have cited Ranma ½ as an influence include Canadian Bryan Lee O'Malley on his series Scott Pilgrim and American Colleen Coover on her erotic series Small Favors.[67][68]

Film director Makoto Shinkai mentioned that Ranma ½ served as an inspiration for the 2016 animation film Your Name.[69] Matt Bozon, creator of the Shantae video game series, cited Ranma ½ as a big influence on his work. The title of the fourth game, Shantae: 1⁄2 Genie Hero, is also a tribute to the series.[70]
