Asuka's official story states that she was taught Kazama-style Traditional Martial Arts by her father, a dojo-master near Osaka, ever since she was a small girl. By nature, Asuka believes very strongly in justice and devotes much of her free time to being a vigilante of sorts, breaking up fights nearby (also, she is seen saving a kitten during the PlayStation 2 version of Tekken 5's opening). At the time in which the game takes place, Asuka is seventeen years old and is a high school student.
Asuka returned home from school one day to find that her dojo was in shambles. The students there had been beaten severely and her father was so badly hurt that he had to be 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.
Asuka entered The King of Iron Fist Tournament 5 in order to avenge her father, who was injured by Feng Wei. She was unable to find Feng Wei, and, as the tournament ended, she returned to her calm and normal life.In the story of Tekken 6, however, Asuka discovered that Jin Kazama was the man responsible for the terrible war going on all over the world. She enters The King of Iron Fist Tournament 6 in order to capture her cousin.
Asuka is more notable as the replacement of Jun, who hasn't been in a canonical Tekken since Tekken 2. Asuka uses Kazama-Ryuu Kobujutsu, just like Jun. Her attacks are mostly single strikes but are very strong. A majority of her moves are launchers, which can be used to start juggles. Other moves are used to stun the enemy, which can lead to a launcher.
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.Asuka Kazama is also slated to return in the upcoming Tekken Tag Tournament 2 game.
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 Tekken 5 ending shows her finally defeating Jinpachi Mishima. She sees an unconscious Jin recovering from his Devil Jin transformation. She touches Jin at finally erases all trace of the Devil gene. Jin finally wakes up is surprised by his surroundings, rises up only to trip Asuka Kazama. He lands face first on her breasts. Both are shocked after this until a small rock falls on Jin as he finally sits up. Asuka angrily asks Jin for an explanation though Jin is still oblivious to the situation, is power punched by Asuka towards a rock.
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 calm and normal life disappointed.However, her life didn't stay peaceful for long, as Asuka discovered that Jin was the man responsible for the terrible war going on all over the world. She enters The King of Iron Fist Tournament 6 in order to capture Jin Kazama.
In Asuka's Tekken 6 ending, it is shown that Asuka is rushing to school while riding a bike. Lili's limousine suddenly appears and bumps her bike causing all her lunch to be ruined. As Lili gets down the limousine, Asuka gets furious and engages her to a fight. Lili's driver is shown getting out of the limousine and running for his life.
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, including the school uniform but 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 arrogant; 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. In her story mode, after defeating her target (Feng Wei), she decides to remain at the tournament in order to "have fun". Her pre- and post-match quotes also demonstrate her confidence.
