Ayane (; Japanese: ) is a character in the Dead or Alive and Ninja Gaiden franchises developed by Koei Tecmo's Team Ninja. She debuted as a hidden unlockable character in the PlayStation version of the fighting game Dead or Alive in 1998 and has since appeared in all of its sequels and series spin-offs. Ayane is the protagonist of Dead or Alive 3 and a supporting character in the Ninja Gaiden series, and has made multiple guest appearances in other games, in particular in the Warriors franchise and Fatal Frame: Maiden of Black Water.

Ayane is a teenage female ninja who was initially shunned by her clan during childhood due to her origin, but into adulthood became highly respected and skilled, assisting her older half-brother and current clan leader Hayate. She also has a complex relationship with her half-sister, Kasumi, a runaway ninja and the Dead or Alive series' protagonist. She has been voiced by several voice actresses including Wakana Yamazaki, Gina DeVettori, Janna Levenstein, Wendee Lee, Brittney Lee Harvey, and Janice Kawaye. She was portrayed in the film adaptation of the Dead or Alive franchise by Natassia Malthe.

Ayane has been regarded as a popular character by media outlets, though with mixed reactions to her personality. While some publications reacted negatively to this aspect, others have considered her an early example of character archetypes found in later Japanese media and a positive example of the Dead or Alive series' writing. Ayane's sex appeal has received significant praise, though critics have questioned its appropriateness due to her age and portrayal in promotional material. As the series has progressed, Koei Tecmo's attempts to reduce her sexualization, particularly in regards to the size of her breasts, have received backlash from fans and caused the developers to voice surprise and reverse such changes.

Conception and creation When developing Dead or Alive for Koei Tecmo, Team Ninja lead developer Tomonobu Itagaki found the ninja character concepts submitted by the design team to be the "coolest" and chose to apply the concept to the game's protagonist, Kasumi. While she was originally intended to be a "kuru kuru ninja" (a type of ninja that incorporates spinning movements into their behavior), Kasumi's characterization strayed from this concept as the project progressed. When developing the upgraded arcade version, Dead or Alive ++, the team decided to introduce the wrestling character Bass Armstrong. Itagaki felt it would be nice to take the opportunity to incorporate another ninja into the title, which prompted Ayane's creation.

While a basic version of Ayane was incorporated into the 1998 PlayStation port of Dead or Alive, the Dead or Alive++ arcade version was given an expanded moveset, using attacks they had originally planned for Kasumi. Itagaki said they had some trouble with the character concept due to the development team's technical capabilities. He added that finding "a balance between onset, duration, and rigidity, as well as the coolness of the motion" in how she attacks was particularly difficult because of the kuru kuru ninja aspect compared to Kasumi's more linear movement. He felt they reached a level of perfection with her in the game's sequel, Dead or Alive 2.

Though initially her attacks were weaker than other characters, the developers gradually balanced them to meet Itagaki's aim of a character that would have a psychological impact on players while fighting regardless of her strength. Ayane's background was also meant to have an impact on players as it focused on her having a hard upbringing. In Itagaki's view, both Kasumi and Ayane were representative of "many unhappy women who have been at the mercy of a male society" and felt this aspect to their portrayal gave them depth and importance. Instead of telling this explicitly within the game, he included a relationship chart with Dead or Alive so players would recognize the key details between each of the cast and imagine the rest. For Dead or Alive 3, she was given Lucha Libre attacks and maneuvers due to the development team's desire to include them somewhere amongst the game's fighting styles.

Ayane's personality is portrayed as a cold demeanor and "extremely serious", in contrast to Kasmui's "soft" personality. As Itagaki felt the latter's personality was symbolic of the Dead or Alive series, Ayane's was regarded as a better fit for the "very hard-edged" Ninja Gaiden series, including her in several of the series' titles as ar esult. The sentiment was shared by Koei Tecmo general manager Yosuke Hayashi, who stated that the image of Ayane "fighting while covered in blood symbolizes the intensity and sharpness" of the Ninja Gaiden games.

Designs

Standing tall, Ayane is a teenage Japanese woman with red eyes and measurements of 93-54-84 cm (37-22-33 in). She has purple hair extending to her neck, with bangs in the front. Several designs were considered during development, including a biker style outfit as well as various ensembles with short skirts and a top that exposed her chest. The finalized design, dubbed her "ribbon outfit", features a dark blue strapless miniskirt dress with a butterfly imprint and an orange trim that exposes portions of her body: shoulders, cleavage, and part of her right thigh. Additionally, the outfit had matching flowing sleeves, stockings, and high heel boots, while a headband wraps across her brow, with a ribbon tied to the left side of it. An orange sash surrounds her waist, tied into a large bow on her back. After the outfit was decided, the development team spent additional time adjusting the color scheme.

In terms of physical appearance, the developers wanted to counter the then-perception that it was impossible to "create beautiful girls in 3D", with Itagaki aiming to create "Digital Venus" designs that would be popular on media character rankings. To this end, particular emphasis was placed on the size and movement of the cast's breasts, in part due to the development team's own preference and what they perceived as a "breast boom" in Japan—an increase in average bust sizes across the nation—at the time. Due to Ayane's original outfit exposing her shoulders, Itagaki gave their animation and movement particular attention. He described the process as "trial and error" and was not satisfied with the results until three days before the game's release deadline.

With Dead or Alive 3, her primary attire was changed to a black ninja outfit that covered more of her body, while exuding a "somber tone". Itagaki preferred it, in part due to his uncertainty towards implementing original ideas with her ribbon outfit. Regardless, the ribbon outfit has appeared in other Koei Tecmo games as a clothing option. In addition to these, Ayane has had a multitude of outfits throughout the franchise including swimsuits, schoolgirl clothes, and other variations of ninja attire. Many designs, such as her appearance in the Ninja Gaiden series, have integrated a butterfly design into the outfit.

Later installments in the series have seen other designers contribute to her design. For Dead or Alive 6, her default outfit was changed to have a hooded ninja theme, a concept that art director Yukata Saito had been considering since 5. Designed by game director Yohei Shimbori, they felt the outfit resembled her Ninja Gaiden attire, and with a white shirt added to give her a more natural look conveyed a "stylish, yet mysterious character". For Ninja Gaiden 4, her design was handled by Tomoko Nishii of PlatinumGames. Here, it was changed to a black and tan semi-transparent outfit with red knee-high boots, an upside-down triangle cutout on the front showing the undersides of her breasts, fingerless gloves, and a dark blue jacket that extend to the elbow. The outfit was intended to reflect the futuristic cyberpunk atmosphere of the game, but also incorporated butterflies and ribbons to show her affinity for "cute" elements. Additionally her hairstyle was lengthened while retaining her bangs, to illustrate her fondness for beauty treatments.

Several times across the series, changes to Ayane's appearance and aesthetics have been met with considerable pushback from players. For her appearance in Ninja Gaiden Sigma 2, they made her face appear older. After receiving backlash from fans, the change was reverted; however, a similar change later in the Dead or Alive series was met with less resistance. For Dead or Alive 5, Koei Tecmo general manager Yosuke Hayashi reduced Ayane's breast size and the amount they jiggle in order to present the game as more "mature", stating that the characters were "no longer content to be eye candy". Players again objected, with Shimbori stating the development team was surprised when fans requested her breasts to be bigger instead, and the change was undone.

Appearances In Dead or Alive and Ninja Gaiden Ayane is a Japanese female ninja introduced in the video game Dead or Alive. Raised by one of her ninja clan leaders, Genra, she is treated as an outcast with her only friend being series protagonist Kasumi. She later discovers she is the daughter of series villain Raidou, who raped the mother of Kasumi and her brother Hayate, making the pair her half-siblings. Angered this information was withheld from her, Ayane turns her aggression towards her half-sister, who she saw as living the exact opposite life she had. When Kasumi leaves the clan's village, Genra orders Ayane to hunt her down. She continues this mission into the game's later sequels, but in Dead or Alive 3, discovers that Genra was captured by the corporation DOATEC who had turned him into a superhuman puppet.
