**Asuka** Koukawa (甲河 **アスカ**) is the third protagonist introduced in Taimanin Asagi 3 visual novel and cameos in the OVA adaption.

She is Asagi's adopted daughter, a prodigy and rogue Taimanin. Asuka lost her limbs in a battle with Edwin Black and was saved by the "Masked Taimanin". Not returning to Asagi or Gosha Village afterward, she joined the group of her savior, the DSO.

## Personality

Asuka is a bit of a "**Gal**", has a **cheerful**, **bubbly** and **playful** attitude most of the time. She also has a **childish, aggressive temper**, that gets the better of her at times. She is upbeat and **confident** in her strength, to the point she can almost come across as careless. Not only that, but she tends to get bored quickly and is rather **impatient**, rushing things and endangering herself or equipment.

When teasing somebody, she exaggerates her movements and voice, and typically uses big gesture, but does all this only if she really likes somebody. Asuka like Sakura, uses a number of nicknames to the people she likes, and even for herself.

At times, Asuka is overwhelmed by situations making her act slower, but she can also analyze her surroundings and instinctively comes up with plans on the fly, her smarts only limited by her impulsiveness. Asuka also allows herself to bend the rules from time to time, and does not hesitate to use deadly force, if it gets things done. Though she is a believer of the Taimanin ideals of justice, she rather follows them as a rogue, to have the freedoms to act against Nomad. Unlike other Taimanin, she is also not that naive and able to work with criminals if it is required.

Asuka is very competitive and wants her abilities as a Taimanin or woman recognized. She will lash out against those that, don't recognize her, for example "being viewed as just a daughter", is something she rejects. She will often smile, instead of stating her own sadness and wants on matters, like her missing limbs or missing day to day normal life.

Asuka gets serious when she thinks about her original family and the Koukawa Massacre, driven by revenge against those responsible, like Edwin Black. Her mood also changes into a very aggressive tone in the canon timeline when Asagi is mentioned, as she feels betrayed by her.

More so than others, Asuka is confident, in her body and tries to use her own sex appeal as a weapon and is less shy about this if confronting those she likes. Though she is popular, she only puts her interest in a few people.

### **Relationships**

Asuka is at first dismissive and challenges Kotaro to fights cause of her pride taking bets, which tend to result in her losing and giving her body to Kotaro. At some point, something alike to trust and friendship forms between the two.
 Takuto | Views him as somebody annoying, his charm does not work on Asuka. Though she agreed to a date before, to make Kosuke pay more attention, she has since pushed the matter aside.
Takuto views, Asuka as another victim he can use and charm, feels only lust and no love.
When Takuko is killed, in TABA he returns as a demon and wants revenge against Asuka.

## History

### Background

Born in year **2064**-**2066**, into the main branch of the prestigious Koukawa clan, that lived in a nearby settlement to Gosha Village. Asuka also is a relative of the side branch clan leader Koukawa Oboro.

When she was very young, her clan was destroyed by an attack party of Black and Nomad. Asuka was taken hostage to convince Koukawa Oboro to join Black and his Nomad group. Oboro challenged Black to a duel instead, which regardless of the outcome would have guaranteed that Asuka would be left alone. Oboro "died" in front of Asuka and her body was taken, but Asuka was left alone afterwards. The details of this event are not fully known however, within the village and since "Oboro" of the ONT Conflict was in recent memory, people just assumed that Koukawa Oboro had gone insane and destroyed her clan for Nomad.

The RPGX timeline, gives information that she was immediately adopted Igawa Asagi. However, as both struggled to understand each other and Asagi was still very active on missions, Asuka lived her very early years at Yatsu Kuro's home even after Asagi's retirement. This continued past the Event ONT Conflict and Chaos Arena events, in which Asagi was retired for some time with her lover and sister Sakura.

As Asagi returned to Gosha Village, with the death of her lover, she took in Asuka once again. Not alone as, she also adopted Kousuke, of the Sawaki clan, brother of Asagi's lover. Both would train to become strong Taimanin but only Asuka was known as a prodigy. Very dedicated as the last of her clan, she developed a light crush on her adopted brother, while living together with Asagi, Sakura and Kousuke in the Igawa Estate.

However, often also came into conflict with Asagi, that was overprotective, to the point that Asuka felt not respected, and she grew jealous of the attention Kousuke had for Asagi as well. Growing stronger as a Taimanin, she stood out with only 14 years, being thrown into dangerous missions together with Asagi, Sakura and Murasaki. Asuka had made numerous achievements. As all references are vague in this case, she trained her skill for possibly 2–3 years but further 2 years before Taimanin Asagi 3, year **2080**, one mission proved too much for her.

Learning that Edwin Black would be around for the mission, Asuka, ignored Asagi's direct orders and went on the mission alone, driven by revenge and blinded. Face to face with Black, she struck with her **wind arts** but was defeated badly, losing all her limbs to his dark mist. Seeing also a demonized Oboro, which did not recognize her anymore, broke her heart and she was just about to die in despair. However, the real Koukawa Oboro, disguised as the Masked Taimanin who had survived years ago and joined the UFS (DSO), saved her and both were able to escape. Asuka would not return to Gosha Village and Asagi, for her own personal reasons. Instead, joining, her two time savior, in the UFS's DSO an anti-nomad group.

Kotani Kenji a researcher and mechanic, developed and improved her current Prosthetics Limbs bit by bit, making her even stronger. Asuka visited her brother, Kousuke, one year later and both kept it a secret, even from Asagi and did irregularly visit Kousuke afterwards.

As part of the DSO, Asuka was briefed on missions in the secret HQ in Japan, hiding in the Orange Industry Building. As a Rogue Taimanin outside of Gosha's control, she became known as the "Steel Reaper" around the globe in the criminal underworld and overtime became almost as feared as Asagi. The Masked Taimanin, became her mentor, commander and mother figure from this point, with Asuka respecting her choice to keep their true identity hidden. Kenji turned into a brother of sorts trying to get Asuka to act less reckless, as she would often break her equipment, underestimating enemies or overtaxed it, in her attacks.

Her Wind Art, came in handy to quickly enter and exit areas and even fly, making her excellent to rush enemies down, create diversions and quickly get out. When not on mission, Asuka went to Midoribashi Academy, but was somewhat frustrated as she never had times for clubs or friends as work tended to be very dense. Though, she was well liked given, that Asuka never had any time she made not many friends and also rejected all suitors.

### Visual Novels

Asuka appeared in both prologue mission of the Asagi-Route and later unlocked Asuka-Route of Taimanin Asagi 3, in the year **2082**.

In the Asagi-Route, when Asagi, Sakura and Murasaki had killed the corrupt Yamazaki Shin and were pursued by his former allies of the Chinese Union, using the bioweapon "Ghoul (Artificial)". Asuka arrived quickly in Tokyo Kingdom and destroyed the attackers with her rockets. Learning that Asuka had been alive, shocked the other Taimanin, but Asuka told them she had no time. However, her interaction with Asagi was much more rough, Asuka refusing to talk to Asagi and her attacks aimed half-haphazardly at Asagi herself. Any talk with her adopted mother failed, the old feelings of Asuka returning and her stubbornly rejecting the idea of being viewed as a daughter first and as a Taimanin second. Asuka, used her Wind Art to escape, leaving the group behind confused.

Asuka, later sneaked into Gosha Village, and beat up Sawaki Kosuke, as a teasing prank to show her power. She did this behind the backs of both the DSO and Gosha, using an isolated forest path, to remain hidden, when Kousuke was on his way home. She knocked him to the ground and teased him, with how much she has grown, both in Taimanin skill and in body. Kousuke, in turn, remained silent by her constant teasing, but Asuka pushed the topic of his lewd gaze and teased him just more. She had infiltrated the village almost a year ago last time and both caught up, on Kosuke's growth and Asuka's current fame. Both, being adopted into the Igawa household, shared many childhood memories.

However, as Kosuke brought up the topics of Oboro and later Asagi's concern and her wish to talk to Asuka, Asuka's mood soured. Now angry at Kosuke feeling betrayed, Asuka said, he was on her side and out of a mix of her personal grief and jealousy, both started to start a verbal fight, which just escalated further. Hoping, he had moved on from his childhood crush and only coming there to impress him. Now, Asuka asked if he still loved Asagi, and was very annoyed by his unclear answer. Asuka pointed even her weapons at Kousuke, with empty threats that she would become the strongest Taimanin and kill Asagi if she stood in her way. She is storming off again at this point, but though the interaction was not the best, in truth Asuka was still supportive of Kosuke.

n her own prologue missions of the Asuka-Route, Asuka is sent out to destroy secret advanced weapons of the Chinese Union. The "Ghouls" and "High Ghoul", as she calls them, created from cells of Edwin Black that found their to competitors of Nomad. As Asuka was a UFS operative, with either destroying pro-Nomad UFS or Chinese Union weapons.

Toughing down with the Special Descent Assist Module, she arrived unnoticed, but soon started to create enough chaos for the bioweapons to show up and defend the base. Having no issue with the lower Ghouls, destroying them in mass, the arrival of the High Ghoul changed this. The High Ghoul skilled enough, to take out even the strongest Taimanin, was a weapon on the level or even higher that of the Raiden Exoskeleton. Getting beat up badly at first, with her Prosthesis, starting to malfunction, Asuka used her Particle Canon, designed to destroy Edwin Black one day, and ripped the monster apart. Asuka, was later recovered and returned to the Orange Industry Building, and Kotani Kenji complained that once more she broke her Prosthesis but with the new level of data, the weapon could be now ready to destroy even the true Edwin Black. The Masked Taimanin, arrived from a UFS mission on the American continent, and allowed Asuka some off-time.

Asuka, was later send to act as a distraction. Attacking prime minister Asai's offices, while other members of the DSO collected Data, as the Masked Taimanin, discovered a clear link between Asai and Nomad. Asagi, that was present at the moment and was given a mission by Asai herself, fought against Asuka, but the blows felt light to Asuka, which she took as being not taken serious. Having, given her people, enough time to collect evidence, Asuka once more escaped, leaving Asai, another political figure Nonomura and Asagi behind.

While back home from a mission, Asuka agreed to a date with Ishiyama Takuto, a popular young man, that nagged her about it for some time. This was to annoy her adopted brother, something that she didn't fully think though at the time. What she didn't know was that Takuto and his brother Ishiyama Ryoji, had connections with the demonic underworld and Oboro. When arriving at the rundown music clubroom, Takuto introduced his brother Ryoji both sons of the major and tried to strong-arm Asuka into sex, as they had broken and used many women before. However, given Asuka's strength both were beaten up, on the spot and warned. However, Asuka was called quickly once more.

The DSO having analyzed the data learned of parts of Asai's plan and send Asuka to save Nonomura Hiroo. Knowing only that Asagi, had been sent on a mission to "kill him". Breaking into the summer residence of Yamazaki Shin. Nonomura Hiroo, was confused that the same attacker from yesterday had returned, saying that Asai had already left, and he knew that Asagi was about to arrive to "discover his corpse". Learning that, both sides had been played, Nonomura had been a pawn and was forced to kill himself to save his family. Asagi, which was only sent to collect information, would arrive and accused of the death of Nonomura, allowing Asai to attack Gosha Village with the Kanda Brigade. Unable to stop Nonomura, that shoot himself in the head before Asuka could react, Asuka stood only a moment longer before Asagi arrived. Asagi, not aware of the full situation, only seeing Hiroo dead, pointed her weapons at Asuka. Asuka herself ignored her and just escaped, rushing to Gosha Village, thinking her adopted brother Kosuke was in danger.
Arriving, in Gosha at night, the Village had already fallen and been taken over by the Kanda Brigade. Asuka, could not find Kosuke and freed those Taimanin student imprisoned in the gym, allowing a skilled sword fighter to escape with them, while she took care of the arriving soldiers. Killing a number of enemies, Fürst a high ranking member of Nomad also arrived, having supplied the troops with tech/drugs. Making the connection between Asai and Nomad, even more clear. Though able to push back, not long after this Edwin Black himself appeared, in truth Asai and Black were the same person. In their fight, Asuka pushed Black to reveal his true form, but at that point was outclassed by his strength. Almost dying to Black, Asuka was saved with the arrival of the Masked Taimanin, which bought her enough time to escape and rush back to the Orange Industry Building for repairs. The Masked Taimanin herself, died in her fight, leaving the DSO leadership headless.

When, arriving the Orange Industry Building, it was under an attack of thugs of Oboro, which used that chance to attack the DSO, Takuto and Ryoji, were given Kousuke that had been transformed into a living meatball by Fürst. Using, Kousuke and the staff, as hostages, the already damaged Asuka, gave up and was knocked out. Kotani Kenji was forced to reprogram her Prosthesis, while she was asleep, and changed it to stimulate the nerves and be fully controlled by the brothers. Asuka agrees to serve the brother's carnal whims and training, with the hope of a counter-attack and to protect the people dear to her. However, the training is harsh and Asuka's mind is pushed to the limit also thanks to AV actors taking over her training for a few days, all while always making sure she remembers that any objection results in the death of another scientist.
Oboro's plan is it to break Asuka enough, so she could be the final opponent of Asagi, that at this point had been captured. As a final cruel act, to be killed by her own daughter, paralyzed by a Slave Brand. Oboro, might or might not hold the soul of the Masked Taimanin at this point, but either way, does not recognize Asuka beyond being a useful tool. The brother is given the meatball Kosuke and Oboro leaves to prepare Asagi. Asuka however, remembers an odd interaction with Kenji in which he randomly started to talk about his family. Remain sane enough, to discover that this was a secret message, using the code, Asuka is able to unlock full control over her Prosthesis. Killing Ryoji, by first crushing his hand to pulp and taking Takuto as a hostage. Using, him she frees the DSO, and behind the scenes makes her way to Demon Arena for the final fight but also frees Murasaki and Sakura, saving them from Demonization.

Filling the pockets of Takuto, with multiple explosives missiles, without him fully grasping the situation, she orders him to move right next to Oboro, when the match between herself and Asagi begins. After, some blows exchanged for show, Asuka detonates the rockets remotely, as Takuto explode, he takes Oboro with him.

Asagi now free of the slave brand is able to move freely and both Taimanin team up against Edwin Black. Turning into his true form, both Taimanin struggle on their own but can push him far enough, thanks to Asuka's Taima Particle charged beam attacks. Feeling pushed, Black uses his final trump card and starts to fuse with Asagi, while using his power over gravity to reset the universe. Asagi reacting fast, throws a particle charged Kunai at his head, able to do so because she now is close enough that his gravity barrier does not matter. Distracted, Asuka charges once more and even large Particle Beam Canon, and this time Black's demonic powers to control gravity and regeneration is fully overcome. Black is vaporized at this point and the Koukawa clan is avenged.

In the epilogue, Asuka and Asagi have reconnected, Asagi respecting Asuka's skill and Asuka allowing it to be viewed as a daughter. Only Sawaki Kosuke, still is a meatball but now thanks to the science staff of Gosha, is able to talk and without pain. Both Asagi and Asuka, swear to each other that they will save Kosuke in their own way, and Asuka uses her new stealth tech to once more disappear but also saying her farewell to Asagi.

### Timeline TABA

Taimanin Asagi 3 does not take place, like at the end of TA3, Asuka has access to Cloaking. The DSO cooperates often with the Fuuma Organization and because of that, she and Fuuma Kotaro come into contact with each other very often.

Asuka is first seen, **2082**, when Kotaro recovered Fuuma Tokiko from Miryuu. Asuka was sent to recover Saya Neo, that Miryuu was able to take in and manipulate. Thanks to Asuka, Kotaro was able to defeat the witch, and Saya returned to the DSO.

Asuka's first solo interaction with Kotaro, in year **2083**, is when she was meant to inform him, that Fire Squad Unit would attempt to rescue Kamimura Maika from him. However, unlike the Masked Taimanin, Asuka didn't trust Kotaro and played a foolish game in which she started to attack him to test his battle ability, hunting him around town. Kotaro escaped at first but later frustrated agreed but forced her to sign a Magical Contract, in which she was allowed to kill him if she disapproved after a losing but Kotaro worded the contract in a way that regardless of victor, she would lose and break the contract and turn to stone, unless "fighting" a battle between man and woman with him. Having sex with Kotaro afterward, left Asuka frustrated by future interactions, as she also felt she never fought a fair fight.

Asuka assisted Kotaro on a mission to collect data from a Demon Gate on a "G"-UFS base, which he needed to find a captured Fuuma Tokiko. Both used the Special Descent Assist Module, with Kotaro egging her on about their past interactions. However, otherwise thanks to the distraction provided by Asuka, the mission was a success.

In year **2084**, when Lilim and Minasaki stole money from Kotaro, and were on the run, they summoned a number of random allies, with Asuka being in the middle as an obvious spy, which leaked the location of the two, to the Masked Taimanin and Kotaro.

Asuka and the Masked Taimanin rescued Kotaro from Fuuma Danjo, when Fuuma Tokiko had been taken over by Danjo's evil eye ability. Though unable to defeat Danjo, which escaped with the help of a Doppelganger, the DSO kept supporting Kotaro in his fight against his father and Task Force G. However, before they could attack Danjo for the final time, Asuka among a number of other Taimanin were turned into a plush by Guignol Faust before being cured of that cursed with Faust's defeat. However, Asagi's Clone of Task Force appeared on the scene, as everyone still was recovering, and forced Kotaro to flee on his own. As Asuka awoke, she was able to follow both of them thanks to her flight and speed. In the final confrontation, Danjo had kept Igawa Sakura (ZERO) as a hostage and was using Clone Asagi to fight. Asuka provoked the Asagi clone, as Asuka viewed it also as an excellent chance to test her ability against even a "fake Asagi". The clone was defeated, by Asuka large laser beam, though with no direct hit, it survived, while Kotaro took out his father. However, as Kotaro's true power awoke with the death of his father, the arriving real Asagi and Masked Taimanin put him under house arrest at a beach. Kotaro escaped not long after this.

However, She fought Kotaro once more after he escaped, from his short term house (beach) arrest by Taimanin and UFS that came as the result of him killing his father. Asuka once more was unable to win, even with a new prototype Flight Suit weapon but is defeated by Kotaro using the power of Lilith Abel Bindernagel, he stole to stay alive.

In year **2086**, during a visit of Asuka in Gosha Village, possibly for her adopted brother, she encountered Kotaro hunting after Hasuba Reiko. Thinking she could help Reiko and also the girl Kuroda Tomoe, as though allied with Kotaro she disapproved of his recruitment method. However, unexpectedly the already loyal Tomoe and only wavering Reiko turned their back on the help and beat back Asuka instead joining Kotaro's side. Confused, Asuka was forced to retreat again.

At yet another event, she saves Fuuma Tokiko as the Fuuma Organization is being overtaken by Tekkain Kaworu and, together with the Masked Taimanin, helps to keep Kotaro's team save. This is one of her last big roles within the story.

In later "what If" events, it is established that Asuka had killed Takuto and Ryoji, at some point just as in TA3, but they return as demons. A good number of the "what if" erotic events are canon, follow-ups to these encounters which refer to her wanting to "win" this time in bed. Other not canon events, involve Asuka being captured in a demon form, which she gained by implanting demonic arms and losing control. One other "What if" also connects to her having finally sex with the human version of Sawaki Kosuke, which had not been turned into a meatball in this continuity, he is later captured and Asuka encounters Kotaro as a third party on the rescue mission, which seems to enjoy making things harder for her.
She like others joins the final raid on the Nomad base, together with other members of the DSO and Gosha Taimanin.

### Timeline RPGX

Taimanin Asagi 3 does not take place. The Koukawa Massacre, now in year **2070**, has been changed slightly though "Black" is responsible somewhat, it is in fact Teutates that raided the village for an artifact called the Tesserac. Fuuma Tokiko was one of the first people that arrived and rescued Asuka.

Young Asuka was adopted right away, but had issues with the young adult Asagi, which also still was very active on mission during that time. As a better solution, she lived the next few years at Yatsu Kuro's home together with Yatsu Murasaki and presuming only later lived some years with Asagi. Though, she gained fame around the age of 14 just as before, Asuka aged up to be in the same range as Fuuma Kotaro and Mizuki Yukikaze.

Asuka here like in TA3 had disappeared two years ago, around **2080**, and lost her limbs, how this encounter differs to TABA and normal canon is unknown but in the same way she had been rescued by the Masked Taimanin and joined the DSO.

The DSO works much closer with the Taimanin of Gosha Village, as a result Asuka appears on some missions as a support, with her being only awkward toward Asagi and not antagonistic. Asuka interacts with the Independent Rangers founded in **2082** and Fuuma Kotaro, just like in TABA she starts to respect him and secretly viewed him as a love interest.

Her academy once again is Midoribashi Academy, as seen in her uniform and with Asuka's help Cedna Arstonna also joined it.

Asuka appears in the early events of **2082**, in which she is often seen with the Masked Taimanin, including when Kiryu Sabato had run away for a short while. On new year, Fuuma Kotaro had been thrown into another Universe by the boar deity Kiyomaro, and he encountered Felicia, Igawa Asagi (ZERO) and Asuka, within that ZERO Universe-like realm. Asuka being around the same age as Asagi within that realm, both had some minor conflict they didn't get into, but also she hunted Kotaro around until he was able to return to his own world.

During an event in the year **2083**, Asuka broke her combat Prosthesis in an encounter with some weaker thugs. While Ange, Alberta and Dolores had mixed feelings or were impressed, the Masked Taimanin, bonked her head telling her to be more careful in the future. Asuka, knew that the birthday of her mentor was coming close and slightly apologetic, took her none combat Prosthesis and made her way to find a gift. However, as she looked around, she was talked to by a stranger. (Yamada Taro) Thinking, he might be hitting on her, she was dismissive at first and surprised when Taro immediately left, leaving a strange data stick behind. Not known to Asuka, Lina tried to get photographs and personal data from Ingrid, secretly making a deal with Yamada Taro, Not for any true malevolent reason but stalkers admiration for Ingrid. However, Lina came too late for the exchange of the data chip and because of her similar look, Taro left the data with Asuka by mistake. As Lina, arrived seconds later, thinking Asuka stole the chip a fight broke out but both women, were able to resolve the issue somewhat. The Taimanin, Kuroda Tomoe was also pulled into the conflict, with cyborg hunter, Senjuin Benkei becoming the main enemy of the three. As things seemed to go downhill, with Asuka not having access to her full arsenal of weapons, Taro appeared again and slashed Bekei, allowing Lina and Asuka to use a combination attack, which killed the cyborg murderer. Talking again about the chip, Lina and Taro, revealed the content of the chip, with Asuka demanding to see it. As the pictures, were mostly Ingrid in swimsuits and other odd positions, Lina turned red, by a slightly judgmental Asuka. However, surprisingly, Tomoe, voiced her opinion that Asuka was the cruel one. Holding Lina's hands, she stated she was the same having her own mentor, Hasuba Reiko, she viewed the same way and wished to have pictures as a form of adoration just the same. As Taro, left the augmenting three girls, behind, Lina became friends with Asuka.

Asuka appeared in a mission regarding Saya Neo, in which she decided to support the Independent Rangers against the choice of the DSO to kill Saya, during a cooperative mission, which came to a disagreement. During her fight with Shido Rinka, Asuka made her way to the "G" agent Hestia instead. Hestia fought Uehara Shikanosuke but was defeated with Asuka's help, allowing the Independent Taimanin group, to bring Saya to Gosha.

the conflict with Muscle Joe and was taken part in a mission together with the Masked Taimanin and surprisingly Makishima Ayame, as they all wished to destroy the genetic clone weapon Ma Chao, a clone and mix between Asagi and Edwin Black.

Asuka and Kotaro first significant interactions is guarding the Luna weapon, on transport. Both exchange some words about their former clans. They are attacked by the Magical Leech, but thanks to a combo attack, are able to defeat the demon that worked for Dragon Gate. Asuka had also dealt with the "Cyborg Killer", Senjuin Benkei and defeated him in their dual.

In the year **2084**, she appeared in minor events, she also assisted Aina Winchester and Nakamori Nanaka, in the defeat of Hans Eduard Victor.

Later on, when a Yukikaze (Future) of an alternative dark future universe, appeared. Asuka fought her off at first, not knowing about the danger of the Tesserac stored in their DSO base, which Future Yukikaze hoped to destroy. As Kotaro and Future Yukikaze, continued to fight and even the Masked Taimanin assisted, the main enemy the Brain Flayer, Arsal tried to recover the powerful Brain Flayer artifact, and kill all the people at the location. Now united, Asuka, Masked Taimanin, Kotaro and Future Yukikaze killed Arsal. While unsure at first, Asuka became convinced and allowed the destruction of the artifact. Learning that her own future self and future Yukikaze were friends, normal Asuka became interested in the Yukikaze of her own universe after that point. Though she viewed normal timeline Mizuki Yukikaze as a love rival, she tried to get to know her and the two of them became friends, just as the future versions of herself and Yukikaze.

In the year **2085**, she appears again in a mission involving, this time, the uncle of Muscle Joe, Duke Muscle. She also became involved during the events, in which Juno used Empusa to cause some chaos around June. Asuka and Linoa Serin, and others, were part of a mission involving the Night Abyss. A mutant creature born from radioactivity and were able to kill the monster.

In a bit of a solo mission, Asuka was sent to Holy Town in the year **2086**. While she disliked the city and the cult which ruled there for their anti cyborg bigotry, she was able to reveal the cult leader of Neo Earth as the real monster. Furthermore, Asuka learned that the cult had used Brain Flayer and had experimented on a Virus, which existed so far only in the Post-Apocalyptic Future Universe. Thanks to Asuka, the P-Virus was destroyed, and the cult leader died thanks to his own mutagenic megalomania.

Asuka appeared, in year **2087** in an important event, featuring a weapon auction. As the machines, and in turn humans became hacked by an unknown force and in proxy Shirley which could hack into human minds, chaos broke out. One of the weapons the Full Armour Bone Revision, which also was present in the auction, proved to be even more dangerous even after Shirley temporary had been knocked out. The out of control robot, made from an unknown metal, still was being highjacked with its armor making it almost fully immune. With the assistance of Fuuma Kotaro and the returning Future Yukikaze, the robot had been destroyed but Yukikaze warned that something called the Singularity had occurred, the metal of the "Bone" was Uranos-Alloy a metal not native to the RPGX Universe, with yet unknown consequences for the future. The constructor of the weapon, provider of metal, as well as the hacker could not be found during that time.

In year **2087**, while having visiting an ice coffee, she had small talks with Lina and Linoa Serin, all three had a loose conversation about cooperation between demons and humans. When the DSO and Taimanin, fought against the Anzu, which caused a large typhoon that could destroy Japan. Asuka was the spearhead, and was given Uranos-Alloy weapons which could be recovered, and an additional flight suit to support her to enter the barriers. As Mishea Silkies, Lune and Karina Cochrane kept the minor enemies, like the Lesser Sylphide, at bay. Asuka was the only one, which could survive crossing the barrier but struggled in her one on one fight against Anzu and was about to be defeated before Lina, which gained the power of flight shortly by her allies also joined the fight. Even united both Lina and Asuka, could not hit the creature which defended itself with electric attacks from its generator or dodged any attacks within its cloud castle. However, a lighting strike from Mizuki Yukikaze hit the monster from the distance, guided by the support of the Taimanin Task Force. The electric generator on the beast was destroyed and Asuka and Lina, could cut its wings, and blasted it upwards into the atmosphere. While falling down out of magic and with broken equipment, they were caught by their allies and congratulated on a successful mission.

### Timeline Action

Taimanin Asagi 3 does not take place and some of the timeline has been moved around timing wise.

She lost her limbs on that mission around age 14 in that Online Universe. However, she has met Asagi without TA3 and their relationship is already improved. As part of the DSO, her base overlooked the training of Igawa Sakuya and Kannazuki Sora. When the Taimanin Task Force requested her help in the search for the Death Wraith and Toyo, Asuka let them to a Task Force G base and a fight against some Oni and "revived" Momochi Toyo. Almost dying, she is at some point saved by Fuuma Kotaro, when her Prosthesis broke down.

Asuka assisted the Task Force later in their combined attack with the Death Wraith, against a Nomad base. She was also able to wound Edwin Black badly, with the help of Igawa Asagi and the rest of the Task Force.

## Additional Material

* Asuka only appears twice, with no erotic scenes in the OVA. Once in a flashback at the beginning having killed an unknown person, telling Asagi she is going to save her brother and a second time on a tree, watching a broken Asagi sleeping with her husband orc. She doesn't do anything else in the OVA, unlike the game which has an entire route for her, which is required for the true ending. Due to her limited screen time in the OVA, her personality is not shown at all.
* In the Manga, a mix of the Asagi and Asuka route plays out, with it ending in a happy ending version of the Asuka ending. Asuka kills, Fürst in this version.
* The Light Novel is split into an Asagi and Asuka version, playing out their respected routes. Additional "what if" material in the art books also has a follow-up of her bad ending route.

## Powers/Abilities

**Main Weapon**: Her artificial limb blades

* **Ninja Art**: "**Wind Art**", "**Wind God Art**" she can manipulate wind to attack and defend or change her movements.
	+ **Wind Shield**: Uses the wind to create a passive shield, protecting her from bullets.
	+ **Wind God Battle Blade**: Combines her scythe-like blades from her artificial limbs with her wind art to give her additional speed. Creates multiple wind blade whirls that move towards her target.
	+ **Wind God Flight**: **"Rising Wind"** and "**Wind God Soar**" clouds her within wind and lets her fly through the air. Soar, gives her more of a silent glide downward.
* **Cybernetics**: She is a cyborg which comes with benefits like;
	+ **Enhanced Strength**/**Enhanced Durability/Enhanced Speed**: Has physical power through her limbs far beyond anything human. Is able to take quite a beating that would have killed most normal people. Has super human speed.
	+ **Arm and Leg blades**: She can extend scythe-like blades from her artificial limbs.
	+ **Laser Beams**: "**Anti-Demon Super-Particle Gun**" Is able to fire a giant laser created out of Taima particles. Asuka introduces it with "**Certain Kill"**, in her strongest version she adds "**Maximum Burst**". This attack is strong enough to kill even Edwin Black.
	+ **Rockets**: Asuka is able to fire multiple, what she calls **"Annihilation Missiles**" from her limbs. These are some of the strongest weapons next to the lasers, but limited in numbers. "**Break**" is a special version that allowed missiles to explode on command.
	+ **Mach Punch**: The backside of her fist is accelerated with jets spewing fire.
	+ **Machine Gun**: Fired from her arm, called "**Obliteration Machine Gun**". Fires 5.56 mm bullets.
	+ **Spiral Kick**: Combines her leg blades with Wind Art.
	+ **Acceleration Mode**: Can use Taima particles to increase her movement speed 1000 times of her normal speed, this does damage her mechanical limbs extremely though. This mode was made to counter Asagi's speed, but still is slower at Asagi at full speed.
* **Particle Control**: As a Taimanin, she is able to manipulate Taima Particles to enhance her physical strength, speed and defense. The particles are also used to counter demonic influences and strengthen damage to demons.
* **Demon Transformation**: A "what If" none canon form in the Online Universes. Like an Inner Demon, increases her strength overall might be closer to a Demonization. Unlike her normal self, 3 of her limbs seem to have been replaced with organic demonic prosthetics. Additionally, a large Lewd Crest on her stomach, has appeared.

**More about this form**:

* **Multiplier on all**: Her abilities are all far upgraded.
* **Changed Personality**: More sadistic, she seeks more and more power. She still seeks out the destruction of Edwin Black.

## Trivia

* Asuka is one of the strongest Taimanin next to Asagi in TA3.
* She is a quadruple amputee.
* Asuka's age is a matter of slight speculation. It is said in all games and her bio, that she was 14 when she gained fame within the Taimanin and went on many missions but leaves it unclear, how long she had been active after being famous. When she went missing for the next 2 years. She would only be 16-17 if one were not taken this unknown time window into account. There is no other information outside of age disclaimers, since this page will give her either 2–3 years in that window as it is "possible" after review and talk.
* As Asuka appears in the very late TA3, she is one of the youngest Taimanin protagonists at that time. Her age between TABA/RPGX/AT remains the same, with other characters in RPGX/AT shifting in age.
* Sawaki Kosuke is one year younger than Asuka.
* As the Online Universes spend real time years to complete, which are also used in game with next year events and so on, she is like all other characters has a "timespan" in these games, in which her age changes.
* Asuka is afraid of horror stories and ghosts, as seen in her future version, but is able to fight Ghosts with no issue.
* With her mechanical limbs, she is able to fight with Asagi on similar footing.
* Can die in one of the endings, if she continues to fight Edwin Black but this is not an ending followed up with any scenes.
* Her limbs are the product of normal technology and hell technology.
* She is somehow worse at cooking and sweet making, than Yukikaze and considered pretty hopeless.
* Though she does not encounter Yukikaze in the main games or TABA. In RPGX, she voices her opinion that, she likes how Yukikaze is straightforward and wants to be her friend. As the Dark Future Timeline versions also become great friends and both are drawn by the same artist, this is no surprise. Even if Yukikaze almost becomes her mother and learns to cook just cause Asuka was horrible at it. In the old canon they did have at least a 4-year age gap, with Yukikaze being much older, but in RPGX and AT, Asuka seems to be one year older instead.
* She is considered to be a terrible cook, with little potential to grow.
* In one of her "what if" events, she has finally the encounter with Sawaki Kosuke, she wanted.
* In the prologue of TA3 on the Taihei Island Base, though she is able to take out all the Ghouls and High Ghoul, it is shown multiple times she is still very inexperienced. Asuka spends most of her rockets on low priority targets, resulting in issues with the fight with the High Ghoul. Her Mach Punch, came out much too strong, and she got stuck on some of the enemies torsos. Her Machine Gun was not effective at all. Trying to take down the High Ghouls with her blades, she was caught off guard and beat up. When turning things around using her large laser, she puts too much energy in her shot, and could not stop firing even after the enemy had been burned away, the constant firing continued until her equipment broke.
