Part 1: Cosmogony
At the dawn of cosmogony 3 Omnipotent being called the choushin, or Top Goddesses are created one after the other, First is Washu, Then Tsunami, and Lastly, Tokimi.
However they understand that their life force comes from an unknown source outside of their dimension and that their must be something above them despite how illogical that is to their supposed omniscience, The compulsion to resolve this paradox in their knowledge leads them to create sub dimensions below them in order to run a simulation to try to manifest a solution to their paradox.
Tsunami and Washu descend to their creation to test their theory on how to manifest this thing while Tokimi stays ascended and creates chaos to try to make it appear.
Washu plans to try to learn everything she can from step 1 to see if she can find a solution.
Tsunami meanwile plans to tries to birth a solution genetically.
Also some form of Akashic records exist in the form of an extra dimensional thing called the Astral Sea which is separate from the Choushin. It's nature is never fully clarified.
Part 2: The bioroid war
A bit over 100,000 years before DUAL! Parallel Trouble Adventure a story happened which can be found in the goodbye 21st century doujin.
As life progressed and advanced in their experiment eventually an ancient and advanced civilization, The galaxy's oldest in fact, managed to stumble upon a giant 3 dimensional Washu floating in space.
She was busy trying to shrink down when they found her as she had manifested far too large. They sealed her to keep her from regaining consciousness and took the three jewels that contained her power as a goddess.
They managed to make 3 bioroid clones of her. B1 B2 and B3. They were combat androids intended for War. Each was given a jewel. B3's jewel should have been in her left wrist but was misplaced into her chest on accident, this allowed her to gain free will.
She escaped from the civilization that created her and ran away into space where she befriended a boy who helped hide her. The other two were sent after her to destroy her.
B3 was found by B2 and after a battle B2 died. But B3 was close to death already and B1 came and finished her off.
Acquiring all 3 gems, B1 tried to kill Washu, but b3's dying scream alerted Tsunami's physical self and she arrived and finished off B1.
Those who were left were given the first line of Royal tree seeds by Tsunami. AHRA and ZINV.
However enemy nations found out about the bioroids from their pursuit of b3 and this caused interstellar war to break out.
This war drove most of the civilizations that were around in the era either to extinction or an unrecoverable decline. This was the end of the Pre-great historic Civilization era.
Part 3: stranded on earth
From Heseiban 3:
Those who had received the royal tree seeds from Tsunami fled from the war and the inhabited parts of space to find a new place to live. They went into cryo sleep as the ship searched for a new place,
Near Earth an incident occurred that fried most of their engines and power generators and killed all their engineers. They settled on earth and built monolithic cities and used the humanoids they found there for labor.
They built giant mechs for construction because it caused the humans to worship and fear them and they cross bred with them and bred the humans to be more intelligent. How ever human men had a tendency to be able to use the machines with far too much power making them very dangerous so they built in a limiter to keep men from operating them. They feared the humans rebelling and them out, but they couldn't maintain their civilization without them.
Ultimately a schism broke out among the aliens, some wanted to go back to a sterile technological existence, the other side wanted to go back to a simple naturalist lifestyle. Many were killed or injured in the fights that broke out between the two including a woman who we only know as D.
D had to be revived through technological means, but she was on the naturalist side.
Her real body had to be preserved in the core computer of the mother ship. Finally the leader of naturalists had enough and decided to unleash the ultimate weapon ZINV on the other side.
D objected and went and stole ZINV and brought it in a smaller ship to meet with the mother ship to reconcile with the science faction but instead they released HIMC a second generation robot designed to take out the naturalist side.
The fight between the two robots killed everyone of the aliens but D. She sealed the mother ship herself, the smaller ship, and Zinv and went into stasis.
Note: The Mechs ZINV and HIMC appear to be named after Japanese occult historical figures Emporer Jinmu and Shaman princess Himiko respectively and this section, Dual and Evangelion to which Dual is thought to be a copy both borrow themes from Annunaki and similarly related occult Esoterica. AHRA from my best guess seems to be a reference to miss uhura or ahura mazda.
Part 4: Dual! The prologue
The year 19XX. a mysterious plate was found while working on a subway construction site by a construction worker . the time line split based on the actions of the construction worker. in one reality he discarded the plate as garbage and in the other he stashed it and casually brought it home. The plate was brought to the nearby university and confirmed to be made from a special metal by two scientists, Professors Rara and Sanada.
the two started investigating the metals out of personal interests, when they began hearing a strange sound from the site of the underground construction; And when they finally excavated it everyone heard it.
The sound was gradually becoming more and more prominent until their country had no choice but to investigate it. They used an excavated the site and a huge spaceship was found deep in the ground under the place where plate artifact was found. Rara and Sanada were the first people, outside of the members of the civilization that created the ship, whom were able to enter the ship.
When others tried to enter after them, they were unable to get into the ship or to make it to do anything, the first artifact was a kind of passport. It was only a few years after they found the ship that it was discovered that the first artifact plate was the key and it was also been a Rosetta stone of sorts to decode the alien language.
As a result of the investigation, it was discovered that the large ship was a spaceship, but the engine and technology for outer space travel and navigation were destroyed.
They also found giant mechs on board the ship.
For some reason The computer units on board that controlled these machines only responded to women. Although the reason behind that was unknown, it seemed that it was due to some biological reaction with their genes that was used as a key.
One night a team of surveyors came from a foreign country and things took a serious turn. Dr. Rara took the ship for himself, and their female assistant, Ayuko Kanama boarded and ran off with him.
However, as a result of the large ship being moved, another small ship was discovered beneath it. And a mech was stored in the smaller ship as well as D one of the members of the alien race that left it behind.but she is badly wounded so they have to create a bioroid body and link her astral to it so she can live normally.
Twenty-two years later, the evil Rara army, were able to take off the gene key and so they formed giant robot army that could be piloted by either man or woman and they declared their intent to conquer the world. Dr. Sanada who was a friend of Dr. Rara knew his personality, so he was able to hack into their computers passwords and copy some of the science data secretly from Rara's network. But ultimately most of it was pointless.
Pilots on the side of the Earth defence force were able to use the dozens of spare computer units that were stored in the small ship to combat the rara army, but all the pilots on the Sanada side had to be female.
Part 5: Dual!
Kazuki yotsuga, the son of the man who found the artifact starts seeing the rara army's battles in the other dimension, he begins writing a blog about it, The Dr. sonada of his dimension created a parallel world traveling device, his daughter mitsuki, whom dr. sonada raises on his own because her mother ayuko "ran away", goes to his school learns about his blog and asks him to come over to her house to talk about it. while he's there her father runs tests on him and mitsuki accidentally sits on a the lever to his parallel world machine and kazuki get's sent to the world where the plate was given to sonada and rara and he was never born, miki follows after him.
Kazuki finds himself in the middle of a mech battle the pilot, yayoi is injured from feedback from her mech during a fight so he takes over piloting the mech for her and he makes sure she is rescued. he goes to find his parents only to find that they don't know him because he doesn't exist in this world. mitsuki along with the military stops him and takes him to their base of operations where the mech world's dr. sonada leads the resistance against the rara army. because kazuki can use the mech and no other man can, only women and because mitsuki briefed him on the situation, he is made a mech pilot.
during his first battle with the rara army mitsuki is in dire condition as she is attacked by an enemy robot and kazuki's mech develops extraordinary power when he feels the urge to save her. he uses this to take out the robot. D Who is other wise quiet and emotionless starts to develop a liking for kazuki. Dr. Sonada moves kazuki to live in the same house as him and mitsuki. Rara calls sonada and trys to get him to reveal how he got a mech to output such power but The UN ambassador assigned to him Ms. Akane Yamano cuts their conversation short to keep it a secret. after the next battle D comes to live in the house with kazuki because she has really warmed up to him,
Dr. sonada moves Kazuki and Mitsuki into the same house with him and D. yayoi the woman he rescued builds a tunnel from her house next door to kazuki's house so that she can come over to cook and clean for kazuki whenever she wants. then she becomes his teacher at his school. she joins the mech team again as a drill instructor. mitsuki gets jealous of her. after hearing that yayoi's grandmother reika, the matriarch of a family known for being influential shadow government figures, is known for her matchmaking, mitsuki sneaks her picture into reika's pile of marriage candidates. an influential man likes what he sees and asks her to arrange a meeting. this meeting unfortunately takes place on a battle day near the battle zone and can't be relocated because mitsuki interjects in the argument with the military and vows to keep a 4 kilometer area battle free. the mech fight gets too close and the date is canceled. mitsuki in a fit of rage knocks out the robot into a building that the enemy army mascot ms. Ra is watching the fight on. kazuki saves her from falling to her death.
Rara decides to send out the big guns to try and capture the white mech pilot (kazuki) a powerful mech is sent which easily captures the white mech. they surrender but it doesn't let it go because they land in rara's territory just before it destroys the mech kazuki goes into overdrive and destroys the mech with a burst of power but it's too late he has to eject himself from the mech. the mech self destructs leaving everyone to assume that kazuki is dead.
miss ra's soldiers find kazuki injured in their territory and take him to miss ra. its revealed that she is really rara's daughter and the mitsuki of this world, mitsuki rara. she puts herself into a trance to play the role of miss ra but is actually a nice meek and gentle person outside of it . she nurses him back to health
she introduces them to her family over dinner, he gives a bad excuse for why he was in the battle zone and her mother ayuko rara sees right through him but doesn't say anything. after talking with mitsuki outside her home one day he stumbles upon some nearbye ruins, he recognizes the symbol on the ruins as something he saw when he jumped dimensions. he touches it and is teleported into the ruins ayuko witnesses this.
mitsuki is shown a video proving that kazuki is the white mech pilot by her friends, she asks that the video be destroyed. inside the ruins a royal tree seed KUMU and mech called HIMC, is alerted to his presence and states that no man should be allowed to pilot the the mechs because of what it leads to which is why it placed a limiter on the mechs, it sounds an alarm and everyone in the base now knows he's an enemy. mitsuki has her friends find kazuki and launch him out in a missile to sanada's side.
Now all this might be because kazuki discovering HIMC unlocked it from a previously sealed area but Ayuko starts acting extra evil. she demotes her husband to janitorial duty and she makes her daughter to fight kazuki in simulations over and over that causes feedback which hurts her. ayuko declares to sanada that she wants to end the war once and for all with a final battle.
mitskis friend warns mitsuki to run because her mother wants to stick her in an as of yet unused mech far more powerful then the others and she is the only one who can pilot it. her mother holds her friends up at gunpoint and hypnotizes her into piloting himc. D has a freak out at seeing himc being used again. as the rara army destroys the base mitsuki R's friends eject themselves in front of kazuki and beg him not to shoot himc because she is inside of it.
Mitsuki R begins to charge an attack to kill mituski S a sealed area in the base bursts open and out comes ZINV piloting itself, it throws itself in front of mitsuki and takes the blow. Kazuki begins piloting ZINV psychically and is transferred aboard zinv. zinv fights and defeats HIMC and saves mitsuki rara. Her friends defect to sonada's side.
As mitsuki rara gets settled into life on sonada's side. kumu assumedly hacks the other mechs or d and gets ayuko rara a full report on kazuki and zinv. mitsuki R asks kazuki out on a date but the ayuko forces the un to turn against sonada and they try to deport Mitsuki rara back to rara territory. Kazuki gets stood up because of this till mitsuki s comes to tell him what happens he rushed back and has zinv keep them from deporting mitsuki. defying the un's order officially cuts off their support of sonada's side. ayuko sends one of the artifacts after kazuki and it dimension bends him and his mech back to his original reality.
in the original reality mitsuki has been back for a month already, and rara and sonada are working together to study the dimensions. kazuki's parent's think he and mitsuki ran off and eloped. the two go and visit his parents after a few weeks of living alone together, they see the people they know in the other world but they aren't the same, as they go home the dimensions start to blend together
Zinv ends up getting sent over, dr.sonada agrees to send them back over to the parallel world.
kazuki arrives in the ocean and he is picked up by sonada's team in the small space ship and told their on the run as outlaws, and Mitsuki sanada has been captured by the rara's so kazuki goes to France to save mitsuki who's being treated as a daughter by ayuko. he is going to save her but mitsuki sonada gets into trouble and he saves her and then the worlds start fusing together distracting everyone, mitsuki S and ayuko escape during the confusion.
Sonada's team figures out that the worlds are collapsing in on each other. rara uses her jealousy to get mitsuki to pilot a now perfected himc into a final battle with sonada's resistance team. D begs kazuki not to fight because he will lose as the worlds meld. sonada begs her to stop but she refuses, rara asks sonada for proof of things collapsing and he provides it. the two discover that the collapse is happening because of both kazuki and zinv existing, both are incongruent parallel versions of one another and one needs to be destroyed.
D however refuses to let Zinv be destroyed because that would make her mortal because it preserves her real body and she fears death. she hacks the ship to prevent zinvs destruction and locks herself in a room to contemplate.
kazuki beg mitsuki s to come home with him were everyone is waiting for her mitsuki rara swoops in and mitsuki sonada knocks her mech out. she gets up and tells kazuki to go rescue mitsuki and mitsuki fired a gravity beam at mitsuki rara zinv pushes her out of the way and takes the blow.
he survives though. himc starts shooting out of her control. zinv is impaled and after debating with kumu who saved her from near death in the past and is preserving her body, d decides kazuki's life is more important then hers. she gets everyone off the ship and takes the ship to confront rara's ship and she suicide bombs it with the ship killing her bioroid body.
kumu tries to convince kazuki that he is the one who has to go not zinv, but kazuki realizes zinv is his equivalent in this world. the real D emerges from zinv's cockpit. she touches zinvs control ball and removes the limiter on the mech which engages the light hawk wings, zinv regenerates itself and rips out himc's core to save mitsuki s and then crushes himc into a super compressed ball.
Zinv confronts the royal tree that was at the heart of the rara base, at kumu's command it begins firing laser like nerve lights. zinv absorbs them into a microblack hole, the electricity in what's left of the tree base starts going haywire. rara urges his wife to leave but she refuses, he drags her out by force.
zinv lets go of the black hole causing an explosion that takes out the tree and kumu.
The team celebrates by preparing to blow up zinv. Mitsuki accidentally sits on the lever. the two worlds fuse into one new world where they all still live together and sonada has married akane yamano. initially kazuki remembers the memories of this world but soon notices everyone else remembers the other two worlds too. He realizes that since mizuki pulled the switch, this was her ideal world. soon after zinv re-emerges from the area where they blew it up, it starts rushing on it;s own towards kazuki and lands in his yard. kazuki, dr. Rara and dr.sonada decide to use to go explore space.
subsequent material implies that once in space, their race colonized mars and then the galaxy for a bit before realizing that most of the galaxy was barren from the last big intergalactic war, they faded out of existence after using every resource they had to launch a galactic life seeding project.
At the dawn of cosmogony 3 Omnipotent being called the choushin, or Top Goddesses are created one after the other, First is Washu, Then Tsunami, and Lastly, Tokimi.
However they understand that their life force comes from an unknown source outside of their dimension and that their must be something above them despite how illogical that is to their supposed omniscience, The compulsion to resolve this paradox in their knowledge leads them to create sub dimensions below them in order to run a simulation to try to manifest a solution to their paradox.
Tsunami and Washu descend to their creation to test their theory on how to manifest this thing while Tokimi stays ascended and creates chaos to try to make it appear.
Washu plans to try to learn everything she can from step 1 to see if she can find a solution.
Tsunami meanwile plans to tries to birth a solution genetically.
Also some form of Akashic records exist in the form of an extra dimensional thing called the Astral Sea which is separate from the Choushin. It's nature is never fully clarified.
