Asuka' Kazama was taught Kazama-style Traditional Martial Arts by her father, a dojo-master near Osaka, ever since she was a small girl. By nature, she believes very strongly in justice and devotes much of her free time playing vigilante, breaking up nearby gang fights by force. She makes her first appearance in Tekken 5, introduced as a seventeen-year old high school student.
In her Tekken 5 story, Asuka returned home from school one day to find her dojo in ruins. The students there had been beaten severely and her father was taken to the hospital. In the next several days, a detective from Hong Kong, Lei Wulong, came to her and explained that the culprit would likely be entering The King of Iron Fist Tournament 5. In order to get her personal revenge and redeem her dojo, Asuka enters the tournament as well. Canonically, she was never able to find and fight said culprit, Feng Wei.
In the story of Tekken 6, Asuka was about to return to her normal life until she discovered that Jin Kazama, a relative, was the man responsible for the terrible war going on all over the world. She decides to enter The King of Iron Fist Tournament to capture her cousin and stop him. Tekken 6 is where her rivalry with Lili begins to intensify, as suggested in the story endings of both characters.
Asuka is primarily a defensive character who relies on punishing enemy whiffs and maintaining distance between her and her opponent with keep-out tools and low-risk pokes. In that regard, she plays similarly to Jun Kazama, who hasn't been in a canonical Tekken game since Tekken 2. They are both practitioners of Kazama-Ryuu Kobujutsu, although their move-lists somewhat differ as of Tekken Tag Tournament 2.
In 2009, Namco licensed a manga series based on the Tekken franchise, which is released under the name "Tekken Comic" and features Asuka as its main star. She is also a playable character in Tekken Tag Tournament 2.
Asuka had received training in Kazama Style Traditional Martial Arts from her father while she was a child. Born with a strong sense of justice, Asuka was well known around Osaka for breaking up fights in the neighborhood.Upon returning home one day, Asuka found pupils of her father had been roughed up. She learned from her father's pupils that an unknown Chinese man (Feng Wei) showed up at the dojo, severely beat them, and put Asuka's father in the hospital.
Several days later, an Interpol detective from Hong Kong (Lei Wulong) came to investigate the incident, mentioning that the suspect is most likely planning to enter The King of Iron Fist Tournament. Upon hearing this, Asuka decides that she will also enter the tournament.
Asuka's (non-canon) Tekken 5 ending shows her defeating Jinpachi Mishima. She sees an unconscious Jin Kazama recovering from his Devil Jin transformation, and (unknowingly) erases all marks of the Devil Gene through grabbing him and attempting to wake him up. Jin finally wakes up, only to trip over and land face first on her breasts. Asuka power-punches him into a nearby rock in retaliation and leaves on a huff. The scene ends with Jin still not totally clear as to what the hell just happened.
Asuka entered The King of Iron Fist Tournament 5 in order to avenge her dad, who was injured by Feng Wei, but to her dismay, he was nowhere to be found, and, as the tournament ended, she returned to her uneventful and normal life. Her life didn't stay peaceful for long, as she discovered that Jin was the behind the terrible war going on all over the world. She enters The King of Iron Fist Tournament 6 in order to capture Jin Kazama.
Asuka's Tekken 6 endings her rushing to school while riding a bike. Lili's limousine suddenly appears and bumps into her bike, causing all her lunch to be ruined. As Lili gets off from the limousine, Asuka gets into a violent scuffle with her. The limousine driver is shown getting out of the vehicle and running for his life.
Asuka does not play a role in the game's main story mode, but she does have a dedicated Character Episode that has her fighting Lili. The former was not even supposed to be in the King of the Iron First Tournament; she was only there because Lili signed her up for up, without her permission. This sort of shenanigans was annoying Asuka to no end, as she thinks Lili is taking the rivalry a bit too seriously.
The ending of the Character Episode varies depending on who wins the match. If Lili wins, she delivers a painful slap in the face to Asuka that sends her spinning to the other side of the ring, and the scene ends with the latter running off towards the former to hit her back. If Asuka wins, Lili informs her that she used her immense family fortune to move into the Kazamas' residence and renovate their dojo. On the one hand, this move helps the Kazama clan as it was going through dire financial straits brought on by the dojo's destruction in Tekken 5. But on the other hand, the two combatants are now going to live under the same roof, with the perpetually annoying Lili also hoping to learn Kazama Style Traditional Martial Arts. To say that Asuka takes the news with bewilderment is an understatement, and the scene ends with her chasing after Lili to demand an explanation for what she just heard.
Tekken Tag Tournament 2
Asuka's (non-canon) ending in this game alludes to her biography as a quasi-vigilante. In the scene, she gets in the way of two gangs that were about to fight. The gangs' underlings don't take her intervention seriously; the gang bosses, who know better, did their best to quiet their subordinates and ask for Asuka's forgiveness. She accepts their apology if they make nice with each other, only to send the gang bosses flying when she sees the two ogling at her breasts. Just for good measure, she even kicks in the face of the mook who called her an 'annoying gang mediator'. The scene ends with her running off to address another potential scuffle, and with the two gangs she just stopped promising that they won't fight each other.
In Tekken 5 and Tekken 5 Dark Resurrection, Asuka's default outfit (in which she is usually portrayed in official art and CG renders) is a blue halter top and blue short shorts (changed to red and black respectively in Tekken: Dark Resurrection), with matching gauntlets and lightly armored boots. Her secondary costume is a more traditional Aikido uniform with gi top, hakama, fingerless gauntlets and matching instep guards. In the PlayStation 2 version of Tekken 5 and the PSP version of Dark Resurrection, she gains two extra outfits. One is a Japanese parochial schoolgirl uniform with a yellow sweater vest and pleated skirt, seen during both her intro and her prologue. The other is a visual kei geisha-like outfit with high-heel sandals.
In Tekken 6, Asuka retains her default costumes from Tekken 5 (excluding the geisha costume). Her new costume is a Matsuri outfit, which is composed of a vest with decorative cords and a bra top, sarashi (cloth-wrap shorts) and open-toed, boot-like sandals.
In personality, Asuka is brash and hotheaded, traits that other Kazamas in the series lacked. Though her profile states that she breaks up fights regularly ("by knockout", as added in the game's prologue), she seems to enjoy fighting herself. This love of fighting explains why (non-canonically) she stays in the Tournament in Tekken 5 to 'have fun', even after defeating the culprit she was looking for in Feng Wei. Her pre-and post-match quotes also demonstrate her confidence.
