Skills/Power: Aiko possesses knowledge of the Art of Ninjitsu thanks to her Mentor Akira, her close combat skills are nearly unmatched especially when she has thought up her own fighting style, physically she is very strong as she can lift enemies that can be considered hulk-sized able to punch through metallic walls with a powerful punch, although she is not invulnerable she can withstand attacks that would almost combust a normal human being, she is able to handle explosions with minor injury and is able to take on impacts that is at tank-levels of strength breaking only a few bones, when berserk she will still take damage but will ignore all pain and will just attack relentlessly, she possesses knowledge of ninpo that gives her access to controlling the elements while manipulating her Aura like her most powerful techniquue known as Raging Mountain God Fist that covers Aiko’s fist in a purple aura that causes great damage from 1 punch, she knows of alchemy too, capable of manipulating the many elements in the environment and uses spiritual power to fight back even the strongest of opponents with her Ki, with enough focus she can also manipulate the area to shift, for example she can make the concrete ground become spikes if she says the incantations in time and touches the ground, she can do this to many compounds though each harder to manipulate than the other, she has excellent swordsmanship and can fight in the ways of the samurai with 1 sword, she knows acupuncture and can press the opponents pressure points to subdue them, she is a master in stealth and can sneak into any area almost undetected

Thanks to her Diclonius heritage from her Mother Aiko possesses Vectors, telekinetic energy that form into long hands behind her that cannot be seen by other unless they are a Diclonius or that the energy in the vectors have slowed down, they can cut through almost anything and move at high speed to the point they can block bullets rapidly, although there is a limit on how long a vector can be, Aiko can stretch hers as far as she wants so long as she has enough Ki to focus with, her Vectors also look like a beasts hands and causes explosions if she smashes with them, she also uses them to leap high in the sky however unlike other Diclonii, Aiko cannot use her Vectors for long as her body cannot handle her power and she will start to melt so she tends to try avoiding them, she can combine them with he ninpo capable of blasting from
them, Aiko is also able to shift them like forming shields to withstands almost any damage, she also makes them smaller to cause less pressure on her body using them as extra limbs in combat, Diclonius can track each other from far
away with their horns, Aiko however from the training with Akira has learnt to adapt and sense everything with her horns, when she focuses her horns can work like antennas vibrating to the environment and people letting Aiko find what
she needs and track down who she is chasing, this also helps in combat as Aiko can hear and sense around her avoiding enemy attack precisely, when she fully loses it Aiko’s body becomes encased in telekinetic energy and her Vectors become gigantic even bigger than her, her face looks monstrous and she looks
like she’s all naked within the barrier, she becomes nearly invulnerable and destroys everything around her easily in this state

 

Weapons/Tools: She
has a high frequency blade with a stun mode for non-lethal takedowns, she has a high-tech armor made for her that protects her from her use of vectors and heals her from damages gained

 

Backstory:

Aiko Kazama is the the daughter of Kouta and Nyu Kazama and is a twin sister of Oga Jr, as a child she was a very happy and playful child along with her brother but suffered an illness that caused her body to slightly melt from her Vectors that awakened, because of this her parents had to take her to her Uncle Kiro, another Diclonius who became President of Japan to unite humanity and Diclonius together in harmony and in later years formed peace with other discovered races, because of his brilliant intelligence with chemicals and technology he discovered that Aiko's condition is the case of inheriting her Grandfather, Oga Tsukino's great power, but because she is more human than her Grandfather her body cannot handle the pressure so she must take medication to suppress her Vectors for her safety

Aiko had been living her normal life while getting treated with medication, then 1 day Aiko's family was attacked by a woman who looked just like her Mother called Delta, her Father is injured to the point he is comatosed, her brother is crippled and her Mother tries fighting back but surrenders when Aiko is used as a human shield, they are both captured and tortured by Delta brutally, to torment Aiko's Mother Nyu, Delta says she killed Kiro making him think he was killed by his own sister again mercilessly, Delta scars and rapes Aiko in front of her making her beg to stop before being taken away, tortured for 6 months Aiko is scarred and Delta tries to brainwash her into becoming a l bloodthirsty killer, she is released and causes a rampage in the city of Kamukara, her Vectors destroy the town but luckily there were no casualties as Aiko faints from her excessive use of her Vectors, she is captured by the miltary and kept in a cell for her to not cause further harm as her Vectors and her head have gone out of control

Aiko was kept in and fed for 6 days until another Diclonius came by to visit, her name was Akira and she was a blind Diclonii who usually helps other Diclonii in need, she is hired to help Aiko in her therapy, though there was more to the blind Diclonii than many thought, Akira was actually an Ex-Reaper of the Reaper Division, a group of Grimm Reapers, Akira specialized in Ninjitsu and Ninpo along with understanding Alchemy, she is excellent in close combat and uses her horns and ears to sense being blind and all, her cane is actually a katana inside that she combats with, being a part Diclonii Akira has mastered her abilities and has even adapted to the point she has become skillful and unbeatable

She sees potential in Aiko and trains her in the ways of combat while also teaching her to master her abilities, over the years Aiko has learned the Art of Ninjitsu becoming stealthy and has learned to use Ninpo that let’s her use her Ki and Aura, she has also learnt the ways of alchemy capable of manipulating the environment around her, she has learned to use herbs and plants as healing items or other medical items, she has trained in surviving hard environments for days as a child, not eating or drinking for 7 days, she has learnt hunting and eating on the animals she catches to survive, as a teen Akira had her tied up and gave her great pain to help her in her pain tolerance, overtime Aiko became hardened from many punishment and strong enough to handle her injuries

Akira has shown her how to use a blade so that 1 day Aiko may become a great assassin in future, however when the day came that Aiko and Akira raided a corrupt official’s building they took down many of the androids guarding him and then came to him to put him down, however Aiko sharing her Father's belief hesitates to kill him making Akira having to do so herself, Aiko saying she cannot bring herself to kill makes Akira doubt her and abandon her student on her own, after that Aiko went back home to her brother who was now a cripple and her Uncle Koji, a friend and partner of Kouta who had to take Kouta’s place in the KPD since he was still in a coma, Aiko felt broken and stopped smiling, feeling everyone will leave her does not take her medication and chooses to die, however while she was dying her brother Oga Jr breaks into the bathroom feeling his sister’s pain, he falls off his wheelchair to help her have her medication, saying he cannot bear losing her too, begging her to not do this to herself and says he will protect her no matter what not caring about his own condition

Aiko now understanding the pain of others realizes that she is needed, she knows the pain of suffering that the corrupt inflict on the weak, so she chooses to fight them back, she donned on an improvised outfit she ordered from E-Get and used that to cover up her identity, she discovers that there is a sickness going on with the Diclonius and their Vectors have stopped working except for Aiko’s and Akira’s, Aiko seeks to stop the new government that has taken over Kamukara and has spread corruption making some laws legal and crime being a major factor of the City, this was worse than the Phantom Incident years ago, mutants and cyborgs have entered the city taking over and causing trouble

Aiko has fought many warlords and have taken down many organisations in Kamukara, she has fought against the Yakuza and has stopped their human and mutant trafficking, making 1 of the bosses of the Kansai Yakuza Kenshin, a metallic mutant, have a grudge with her and wanting her dead, when stopping a cargo shipping of the Yakuzas Aiko is attacked by Kenshin and they both fight face-to-face, Kenshin having an advantage in brute strength nearly overwhelms Aiko but she fights him back and uses her Vectors to break his armored skin cutting out 1 of his eyes and then smashes him into the ground with 1 of the containers dropping on him knocking him out, this makes him hate her even more wanting to kill her desperately

Aiko in high school tends to get a lot of attention from her looks and is constantly being flirted by many guys, particularly the school common bully and rich boy, Takashi, Aiko always says she is not interested with him constantly harassing her, though the Student Council Kousuke Ito does defend her but says to her that he was saving them as he knows how dangerous Aiko is in close combat teasing her, not admitting he has feelings for her, Aiko is then being constantly asked by the newspaper club leader and only member, Choko Nishimura about her life in School with Aiko blocking her out, though this wasn’t their last meeting together as Choko witnessed a mutant being murdered by a professional assassin is now being chased by this dangerous man, she seeks help from the police but they find her story unbelievable as there was no murder mentioned and the dead man was gone, she required proof of this which she left back at her home, too scared to go out on her own, Choko asks Aiko to escort her, though Aiko says why she doesn’t ask the police she reluctantly agrees when Oga Jr convinces her and escorts her to her apartment, she waits outside for Choko but senses someone else in the apartment and sees Choko getting kidnapped trying to save her

Aiko then dons her outfit and searches the city for Choko and find tracks her down in the abandoned Maple House, once Aiko’s home before it was burned down by Delta, Aiko finds Choko and the Chinese Professional Assassin called Gai Zhao, who had a high-tech armor that could shrug off Aiko’s attack, they both fight in the rain with Aiko sustaining injury but she eventually dismembers Zhao’s arm and hits him into a pillar knocking him out, saving Choko but not revealing who she is, she tells her to spread the story, just not to the police as they maybe on the new government's payroll, she advises her to use the internet to her advantage, next day it is shown of the mysterious killings caused by the Chinese assassins that may possibly link to the Triads

This gets the attention of many of the mob-bosses of Kamukara and they start to worry that this masked vigilante will cause trouble for them in future, so they work togther to try and take her out, when a diclonii girl is taken away from her family by the Yakuza, Aiko tries to save he but is led to a trap where she gets badly injured and barley escapes with her life, falling into the sea half-dead, she is later found on a beach by Kousuke who happened to live in a beach house nearby and thanks to his medical expertise he patches up all of Aiko up and learns her secret, he tell her to rest after she wakes up after a few hours, Aiko knowing what will happen to the little girl that was kidnapped did not seek rest but to leave so she may save her, but is too badly injured to do anything, so she meditates to ignore the pain she is in but is then interupted by a cop who questions Kousuke about any suspicious activity around the area, but Aiko can sense that he is a Yakuza member and is trying to find her, when he leaves she knocks him out with Vector before he reported back, Aiko then traps and interrogates him on the girl's whereabouts, after tearing off his arms and gouging his eyes in, he tell her the location, now knowing where she is, Aiko throws the corrupt cop into the sea but does not kill him, Kousuke questions Aiko's methods but is glad she chooses not to kill her enemies

Aiko finds the warehouse that the young Diclonii is being kept in and remebers her past life as a child being tormented and tortured, she did not want her to suffer the same fate and breaks in taking on every mutant Yakuza members, though Aiko hasn't fully recovered, her determination kept her going as she took down many of them 1 by 1 knocking them out, after defeating the Yakuzas, Aiko rescues the girl and takes her back to her family and relieved that she did not suffer like her

Aiko is now nervous that Kousuke may say about her secret but he says that her secret is safe with him so long as she does not endanger herself and thanks to Kousuke's medical expertise, he fixes Aiko's wounds she gains from her "night shifts", during her walk home from school Aiko is drugged & randomly kidnapped by a mercenary called Eddie Ashley who was sent by an english business man called Vernon Kane, Eddie was sent to track down every Diclonius in the city to find out who the vigilante with the mask is, Aiko wakes up trapped in a factory where the Diclonii girls are being interrogated, she breaks out and finds her bagpack with her spare outfit, putting it on she takes down the henchman and goes up against Eddie who turned out to be a part wendigo with great gunslinging skills, after their fight, Aiko has him trapped under construction materials and interrogates him on who is in charge of all the crimelords in Kamukara, after inflicting great pain to him, Eddie eventually says "Seinto Kakuzawa", however after saying that he tells Aiko to kill him as he knows what the Kakuzawa will do to him for mentioning him to another, not taking his chances Eddie shoots himself shocking Aiko, now she seeks to know who Seinto Kakuzawa is

Over her search on the Internet she discovers the Kakuzawa Lineage and their experimentation on Diclonius in the past, but she discovers they were wiped out by an unknown group, she tried discovering who Seinto Kakuzawa is but did not find any file of his existence, she then asked Koisuke if he knew anything but alas did not know much only that he might know the group Kakuzawa could be in, the Romulus Project, knowing this because his Father was 1 of them before he was killed by them, Aiko then searches for anything on the Romulus Project and learns they are the new goverment of Kamukara, now knowing this Aiko seeks Kakuzawa and stop his reign of terror with the other Mob-Bosses, she starts with the Yakuza by tearing apart their drug lab greatly injuring the other Boss of the Kansai Yakuza Ryuji, sworn brother of Kenshin and a mutant with bladed string-like finger that pop out from his normal fingers when he uses them, though he escapes and informs Kenshin about what happened, this drives Kenshin to search for answers and finds their corrupt cop in the hospital barely able to wake up, he tells them he was attacks by the "Masked Demon" herself and that there was a boy trying to hide her, because of this Kousuke is captured and tortured to tell about the Masked Demon, Aiko searches for him blaming herself for endangering him

She searches for him around the City but because she was panicking of what her mistake will do to Kousuke she could not sense him properly, she then remembers her training in focusing her horns with a calm and collective mind, from that she senses the city and pinpoints Kousuke’s position, finding him getting interrogated by Kenshin, she sneaks in the Building and takes out the henchmen and then fights Kenshin and Ryuji head on, they both give her great challenge in both strength and area advantage, however Aiko defeats the 2 by bursting Ryuji’s face and breaking off Kenshin’s right hand with her Raging Mountain God Fist technique, ironically this impresses Kenshin more than enraging him more, Kousuke then knocks him out with an object in the area and acts he is ok, but Aiko shows she was extremely worried for him and takes him to her home and says he is her new boyfriend to not cause any suspicion on who she is, she patches his wound and thinks maybe they should stay away from each other and that her activities is making things worse in the city and thinks about giving up, but Kousuke mentions of the little girl she saved and all the people she has saved in the past, though Aiko thinks of those she hasn’t saved, Kousuke reveals he was scared for his life back with the Yakuzas and tells her imagine this happens to others without people like Aiko to stop them, encouraging her to keep fighting, they share a kiss first time after Kousuke’s treatment

After a few days, Aiko finds a group of Yakuza members and interrogates them for where the other Yakuza shipments but 1 of them begs for her not to murder him and obliterate him, this confuses Aiko but she discovers she’s been framed for murdering Ryuji and the Kenshin has sent a bounty of 500 Billion yen to any who captures her dead or alive, she is now on the run and searches the whole city for Kenshin, after finding the airship he was using to go around the city with, she infiltrates it but it explodes randomly and crashes down into the slums of Kamukara, Aiko is slightly injured and finds Kenshin and a few of his henchmen left injured from the explosion and crash, she takes them out and fights Kenshin 1 last time, she overpowers him but is then stopped by the KPD Swat Teams, she nearly surrenders but find they have been hired by the Romulus Project to kill Kenshin, she fends them off and takes an injured Kenshin away, she goes hiding in an old facility island that use to be known as the Lebensborn Project owned by the former Director Kakuzawa, she tries to get answers from Kenshin but he passes out from his injuries, she tends to his wounds but finds it difficult to try and treat someone made of metal, she calls for Kousuke on her phone and asks for advice on how to treat Kenshin, much to Kousuke’s dismay from their last meeting, he advises her to gather any metallic material and a blowtorch to cover his wounds, she then waits for him to wake and stays with him

While waiting she hums a tune to calm her nerves from what is happening, Kenshin wakes and hears the tune finding it lovely, he asks what it is, Aiko doesn’t mention where she heard it from, only saying it’s called Elfenlied “Elf Song” a poem written in German by Eduard Mörike that was turned into a song, she says she usually hums it to calm herself, Kenshin seems to also have calmed down from his rage towards her and found out it was Kakuzawa killed his brother then tried to kill him by 1 of their failed experiments that combusted, explaining the Airship’s explosion, though Kenshin mentions they should be careful and that there is a powerful Assassin that came from another world that Romulus hired to hunt them down, the Ice Master Toketsu was hired to capture or kill the Masked Demon of Kamukara

He is very good at his job and never seems to fail, he does go a little out of control should he find too much amusement in his hunts, after their cooperation they are found by Romulus and are tracked by Toketsu and his Cryotites Troops, they both are surrounded and try to escape but fight many Cryotites with the Facility to survive, they eventually break through underground and try to escape through the pipes, but are attacked by more Cryotites, they fight through them but Kenshin realizes that he is slowing them down from his injuries and chooses to stay behind and help Aiko escape, he then tells her if she wants to expose Romulus, she must find Vernon Kane as his industry is in leagues with the Romulus Project, he also asks her to to find his younger sister who is in the hospital and will be killed if left behind, but before she leaves, Kenshin asks for 1 last request and asks for Aiko to show her face to him before he dies, though doubtful Aiko removes her mask revealing her face which makes Kenshin upset he didn’t get to know her in friendlier terms, he heads back and holds back the Cyrotites but is then killed by Toketsu being frozen to death though not before smirking at him, he breaks him to pieces

Aiko heads to the hospital to find Miyuki, who was getting treated for her condition that was an unknown mutation, she finds her nearly assassinated by Toketsu who was calming her and was about to stab her with ice, but Aiko steps in and stops him, she then fights Toketsu head on but he is very tricky and causes Aiko great pain, he then traps Aiko in ice and torments her by freezing bits of her blood inside her forming spikes in her, he then proceeds to cut her head off but she then uses her ninpo on herself setting herself on fire covering her whole body and attacks Toketsu brutally burning him with her punches and Vectors nearly killing him but stops herself at the last second, she stops the fire but is badly burned to fight further, she takes Miyuki out of the hospital and hears Toketsu laughing as he has now developed an obsession of her as he bleeds on the ground, Aiko has given Miyuki to be taken care of by Kousuke back home and searches for Kane, she eventually finds him about to leave in his jet and ambushes him to find information, however Kane reveals to be really a Wendigo and changes form into a then clawed beast then attacks Aiko, but because Aiko hasn’t quite recovered from her fight with Toketsu and her burns, she fights Kane into a jet warehouse and beats him but sustains many cuts and injuries from Kane’s claws, she fends him back for a while but succumbs to her burns and Kane tries to eat her but is stopped by Akira who cuts him in half but he escapes as he cannot die easily 

Akira reveals she has comeback to Kamukara after her mission in Barcelona was nothing more than a wild goose chase, she informs Aiko she is searching for a oldman named Roberto Rodriguez of the Deadman Corporation, a company that creates super cyborg beings, but Akira reveals the Rodriguez is actually part of a Supernatural group that worshiped a Lord from the another realm, this Lord was a being that could destroy all life should he be released, Aiko then works with Akira but is angry with her for abandoning her in the past, so she does not trust her completely, Aiko request that when they raid the Deadman Corporation she does not kill anyone, but before they raid Akira gives Aiko her wooden sword that helped her channel her energy, they infiltrate the Corporation and take out many of them, Aiko then finds a young boy with horns but wasn’t a Diclonii but a different sort of mutant, before she can inspect the boy Akira rips out the boy’s heart with her Vectors and bursts it, then disappears heading back to Aiko’s old treehouse waiting for her there, when Aiko finds her she asked why she killed that boy mercilessly and didn’t listen to her, Akira says that was no boy, it was a monster saying that boy was a child of Katastrophys, a being who believes in destruction and makes it into a religion, if that boy lived on it would end Kamukara if it evolved, Akira had to do what she needed to, Aiko now even more distrustful of Akira than ever for not telling her that before, but Akira knew of Aiko’s beliefs and saw she was still a child that can’t do anything on her own, the potential she saw in her was false, enraged Aiko fights her in the treehouse, Akira being her Mentor was difficult to fight but Aiko bursts her out of treehouse and nearly finishes her off with Raging Mountain God Fist attack but stops herself again from going berserk, she gives Akira her bag and tells her to leave Kamukara and never comeback, Akira now sees the potential in accepts her demands and leaves while injured from her fight with Aiko

Aiko finds a necklace in the rubble of her treehouse which was a present she gave to Akira years ago, seeing this she was slightly happy to know that she kept her in mind all this time, though she still didn’t smile, back home Aiko is visited by her Aunt Maya and Uncle Bando whom have been overseas in Italy living there, they know of the situation Kamukara is currently in and seeks to provide information to Koji, Bando knows of Aiko's identity as the Dark Demon of Kamukara and provides her detail on the Kakuzawas as he did business with them before, but before they could discuss more information, Seinto Kakuzawa reveals his face to the public and says that he will run the place of Kiro Tsukino and make Japan safe again, with the public praising his nobility, Aiko is enraged and sees that exposing him now as a fiend is useless now, she will need to find real dirt on the President who now shows his face as a hero, Aiko now seeks out the all the Mob-Bosses in leagues with Kakuzawa and gather information but it is not enough, Aiko nearly loses hope in the fight, then Aiko is called by Oga Jr and he informs of Mayu and Bando's death, saying their heads were found impaled on the Kamukara memorial

It appears on the news and a message was left behind in blood saying "It's been long little Aiky", only 1 person in the world calls Aiko that and it was the woman that broke her family apart and took her Mother away, Delta, she tracks her down in a Factory where exo-armors for the Romulus Soldiers were being made, Delta taunts Aiko and reminds her of their "fun time" together and says she had fun breaking her Mother and taking Aiko's virginity away at such a young age, enraging Aiko she fights Delta but is constantly taunted and countered brutally by her, Aiko gains many cuts and injuries from Delta and starts to become exhausted, Delta then reveals she had a lot more power hidden inside her and she's been holding back all this time, she then brutally attacks Aiko mercilessy, after brutally injuring Aiko, Delta binds and traps her with her Vectors then continues to molest and torture her getting aroused from her pain and agony, she strips Aiko naked and brands her with some of the heated metal around the area, she tortures Aiko waiting for her to beg for death, however Aiko insteads lets her killer instinct take over again and she breaks out, Aiko now berserk ignores all the pain and savagely fights Delta tearing her bit by bit but then stops after nearly killing her, Delta hangs on to a railing as she nearly falls to a tank full of magma, even after what she put Aiko through, she still tries to save Delta and grabs her automail hand but it breaks off and Delta falls in to her death, Aiko then sits there bleeding, broken and exhausted while stripped of her outfit, but just before she could catch her breath, Toketsu finds her with an evil grinning stare at her

With her blood covering her face Toketsu could not recognize her as Aiko, however she was too weak to do anything and Toketsu holds her down molesting her while licking her blood, he was happy to see the Masked Demon again, though he wished she was at her best, he wanted to cut her up and experiment on her when he takes her with him, but Kakuzawa comes in and says that will not be necessary as he chooses to just kill her, enraged by the sight of Kakuzawa, Aiko goes berserk again and tries to kill him but is easily overpowered by his godly power, her Raging Moutain God Fist technique is stopped by Kakuzawa as he grabs and melts her right hand off, Aiko defeated by the New President feels her life coming to an end, to make sure of this Kakuzawa forms a sharp pole from the broken metal around him and impales her in the chest finishing her off, he then has his right hand man Leo burn down the factory with her inside, Aiko now left for dead nearly breathes her last breath but is saved by an unknown man in a red who carries her out of there while the place burns down

Aiko then wakes on a bed fully healed and her hand has regrown, she then sees the man in red reading something and sees he is a Diclonius himself, he reveals himself to be Kiba Strife and does not remember much of his past other than the fact that Toketsu maybe connected, Kiba then introduces Jurou Tsukino who is the real brother of Aiko's Mother Nyu, Jurou has been working underground to find a way to defeat Kakuzawa and reveals it was his orders that lead to Kiro's death, but Kiro's technology remained, using the healing bath on Aiko helped her recover and fixed her up, because Kiro's son Ryu is still young Jurou is in charge along with Kiro's wife Hoshi and they ask for Aiko's help, but Aiko is doubtful in her abilities and gives up her fight, but Kiba comforts her and tells her that even though he does not exactly know everything about himself, it does not stop him from turning the wrongs to right, he fights for the weak no matter what the cost because he wants to do it, he says they can't do this without her as he reveals she can kill a God, hence why a Vectors are as powerful as her Grandfather's, after calming herself Aiko then talks with her Uncle Jurou who informs Aiko that her Mother is indeed alive and is being kept preserved within Romulus, with this knowledge Aiko is now driven to fight against Romulus

Jurou then gives Aiko a high-tech suit that her Uncle Kiro made for her to stop her Vectors from harming her, though Jurou modified and changed it for combat purposes, Aiko does ask for it to he redesigned and is oufitted with many gadgets Jurou prepared for her, with Aiko set up in her new armor her and Kiba plan to raid and take down Romulus with the resistance, Aiko is given her own personal jet and flies in the Fortress, she takes out her new sword as her wooden 1 is broken, her stunblade takesdown many hostiles without killing them, she fights through many and many of them til she finds the emitter responsible for suppressing the Diclonius of their Vectors except for hers, she finds out it is her Mother who is being kept alive and being used as an living Anti-Vector Generator, Aiko then battles Kakuzawa's right hand man Leo who reveals to he a mutant with a muscular lion and scorpion-like body known as Chimera, tearing out of his human body Leo tries to kill Aiko but Aiko overpowers him as she can now use her Vectors and ninpo safely without straining herself, she breaks out her Mother, unfortunately Nyu has no idea what's going on and does not remember anything, she doesn't even know Aiko, when Aiko removes her helmet she cries realizing her Mother doesn't recognize her at all

Aiko then puts her head on her Mothers silently singing her Mother's song Elfenlied to her from her sadness, Nyu recognises the song and remembers everything, she then cries in joy seeing Aiko again and the both cry in joy after so many years off separation, Aiko carries her Mother walking home as Kiba burns Romulus down with the resistance and Kakuzawa goes into hiding Aiko hides her armor and jet as she brings Nyu back to the family, surprising her more she finds her Father is back home awakened from his coma, it was revealed that Delta's Vectors were cursed and kept Kouta comatose but after her death Kouta woke up recovering, with the family back together again and they celebrate their reunion, Nyu remembers seeing Aiko but doesn't remember her as the Masked Demon, Jurou joins in on the celebration with Kiro's son Ryu and Kiro's wife Hoshi along with Kiba whom starts to remember who he is slowly, Jurou gives Oga Jr augments that are humanlike so that he doesn't need his wheelchair anymore, Jurou also say that Kiro's old lab Sakura Enterprise is up and running again and will continue Kiro's research along with running his place as President, Aiko is now relieved to see everything going well again, but their peace is cut short when a broadcast sent to everyone's television

Kakuzawa makes an announcement that his Noah Project is complete and that those chosen to live for the new world shall be sheltered while he destroys and reforms it into a Utopia of peace, after that the world shakes and starts to crack as his power starts to decimate the world, Aiko has Jurou send a her family to safety while she puts on her armor and goes after Kakuzawa who was causing the Chaos from the Lensborn Project Old Facility Island, Aiko finds him and takes out his troops, then goes up against the False God himself, this time Aiko was determined to stop Kakuzawa, they both fight equally in strength and power nearly decimating the whole island, Kakuzawa proves to be godlike overwhelming Aiko, but as their fight carries on Aiko gains the upperhand and defeats him, though Kakuzawa chooses not to stay down and uses his power to make himself gigantic to try and destroy Aiko, though she has a difficult time Aiko enters her berserk mode but since she is wearing her armor she controls it and overpowers Kakuzawa greatly making him go back to his normal size weakened, he says "do you really think a silly girl like you in a ridiculous costume can change the world?" before laughing, then does 1 final punch knocking him out, with the world saved Aiko leaves Kakuzawa to the military before heading back home

Back home Aiko discovers from her Uncle Jurou has taken Kakuzawa into his custody and made sure his Godlike power is nullified, relieved Aiko joins her family on their holiday in Okinawa, Kousuke tells Aiko he will be leaving Japan for a while an wanted to inform her before he goes overseas to become a Doctor, happy for him they share 1 last kiss though is shocked to see Aiko is smiling as he has never seen her smile before in his life, Aiko joins her family in their family photo, Choko arrives saying she now works for the Daily Daze and publishes stories for them now, her recent story and best-seller "The Nightdemon of Kamukara" gained many interest on the Superheroine who took down Romulus and Kakuzawa while saving world from ending, Aiko found it cheesy but liked the name, though Aiko is finished with Romulus, her days of crimefighting hasn't stopped as she fights to protect the innocent and stop the evil around her city, Aiko puts on her armor and leaps into the city to fight on as the Nightdemon
