OHH, your builder being like fluttershy 😭❤️
I really love the old world survivor idea!! Did she manage to save anything from her old life? Is there something she wishes she could've saved? Does Pen discover her true identity at any point?
Sorry for lots of questions, I'm really excited to read what you're comfortable sharing!!
Thank you so much for being willing to read about my Builders.
Honestly, their backstory is so extensive that I even made a separate post just to add extra lore.
If we follow the most original version of the story—keeping it less OOC—then my Builders have basically already become people with nothing left.，only have there body and memory，
But they still have this glorious motherworld: old-world ruins, ancient relics, buried technologies, and forgotten civilizations—still waiting to be excavated, restored, and brought back into the light.
Yukiyo would focus on restoring ancient artworks and cultural artifacts. She also wants a respectful heterosexual partner—someone who truly respects her—and she wants a family… and children.
Serjio would care about crops, spices, food supplies, fruit—things like that. On a broader level, he’s focused on rebuilding the entire system and structure of the world.
Would Pen eventually discover their true identities? Yes.
A sentimental girl who secretly cries while staring at the stars late at night… and an sunproff vampire ally who simply won’t die—Pen would absolutely investigate them alongside Matilda. He might even find their wanted posters through interstellar broadcasts.
And now: SUPER ULTRA “OOOOOOCCCC” TIME!
On the surface, it looks like a loud, carefree church guard dealing with a newly arrived Builder girl.
In reality, it’s a confrontation between a highly trained intelligence agent and a cold, ruthless engineer who once developed planet-destroying, star-killer-class weaponry (and she might be suffering from amnesia).
In my version, the effects of my female Builder’s immortality experiment begin to fail. She starts to grow again—she starts to age.
Yukiyo’s biological age was frozen at nineteen, but now the “freeze” is lifting. She’s a fiercely rebellious girl. In the future, she once ran away from her overbearing parents—escaping an arranged marriage, escaping the cliché life of “marry, obey, and give birth.” That was why she chose interstellar study.
And because of that, she cannot view the My Time universe with the “Overview Effect” perspective the way her teammate—the male Builder, Serjio, a successful immortal—can. He can look at everything from a macro, cosmic distance. She can’t.
Her fragile flesh-and-blood body has returned. Hormones that never had the chance to exist for centuries—dopamine, estrogen, prolactin—begin to surge in a kind of revenge overflow.
It turns her into someone much softer, far more sentimental, far more easily hurt.
(Don’t worry—I also write another Builder who carries the rational side. But Yukiyo carries the emotional side.)
She used to be the one resisting her parents’ pronatalism, which was exactly why she left her family. But later—after the disasters in the My Time world—she loses contact with them entirely. Now she is a helpless, lonely girl who truly feels like she has nothing left.
She begins to rethink pronatalism. She starts analyzing what it really means—especially after witnessing the extinction of other organic life forms.
That brutally selective process.
The extreme loneliness of having almost no fellow Earthlings by her side.
The despair of watching her homeworld collapse while being utterly powerless.
The repeated agony of losing not just her family, but her entire homeland.
And wounds even deeper than that…
On top of the hormonal impact, all of this forces her into reflection—and even repentance—for her past rebellion.
And in the My Time world, there is also a kind of “magic rule”: if you don’t marry, you can’t have children.
This forces her to lower herself, to compromise—and under the influence of those hormones, she begins to reshape herself into something like a Yamato Nadeshiko woman, trying to “soften” Pen, who claims he “doesn’t like the concept of marriage.”
(But in the game, Pen literally prepares a diamond ring—so at that point I can only go build my Duvos plotline.
when Pen has to hold himself back. He can’t expose his true identity.
He pretends to dislike the idea of marriage, keeping everything carefully contained.
But the moment victory is secured—
everything he’s been suppressing detonates all at once.
)
There’s also the issue of their bodies. Serjio would say something like:汝身乃系血与肉，爷活千载尚不愁
“Your body is flesh and blood. I’ve lived for a thousand years no need fear anything.”
But Yukiyo has to worry: she can hurt, she can tire, she can be injured, she can die. She can feel heartbreak. She can cry.
And that’s exactly why Pen gives her an immense sense of safety and protection—so much that she genuinely admires him and feels grateful from the bottom of her heart.
(In the game, Pen even carries an exhausted Builder home when she collapses outside. And there were earlier “hero saves the girl” moments too.)
The destruction of the old world is partly inspired by The Animatrix worldview.：The Animatrix - The Second Renaissance Part II (1/2) [HD]
My Builders are deeply afraid of machines and robots because of that history.
But when they see Pen crushing steel with his bare hands,
they can’t help but feel a sense of awe—
almost reverence.
Yukiyo, on one hand, is grateful for how much Pen helped her during that period.
On the other hand, she is still analyzing—
If her future offspring inherit Pen’s genetic traits, would they survive better in this post-apocalyptic world?It seems she may no longer be able to do it herself. Could her descendants return to the cosmic stage in the future?
And then the hormonal explosion pushes her into becoming completely love-brained.
Even without the hormones that make her soft, she would still choose Pen—
but she would coldly reduce him to:
a chromosomal contributor to the genetic makeup of her future offspring,
and—
a stepping stone toward seizing control of Duvos. even the the whole my time wolrld。。
Yukiyo and Pen likely realized long ago that they are both people with very deep minds and very deep masks.
aiio Yukiyo and Serjio ‘s background is so complicated

Arlenter Prison 阿兰特尔监狱
— an interstellar prison that once held some of the most dangerous criminals across the galaxy.
After the collapse of the Old World, when there Earth passports were rendered invalid and waves of blackmail and political purges began, Serjio, the protagonist of my story, was also imprisoned there.
However, he was anything but broken.
He remained full of life and defiant inside the facility—
—and yes, he eventually escaped.

“china GEO”瓷器地质(company name)
china Geo This is Yu’s family enterprise。china Geo was originally a state-owned enterprise on Old Earth.In the final stage of Earth’s collapse, it was acquired and restructured by private capital.
Here, “China” no longer refers to a modern nation, but to a lost ancient civilization and technological heritage.The word comes from china, meaning porcelain
.China Geo controls and operates the most basic and irreplaceable resources:H2O,and O2， geological resources, and ecological restoration.
During the collapse of Old Earth, they provided free water and oxygen to many Earth refugees, prioritizing survival over profit.This is Yu’s family enterprise.
When Old Earth collapsed, her family was relocated to an off-world colony and survived.They were out of contact for a long time, leaving Yu nearly hopeless, but they eventually reunited…..The city they lived in is called Neo Addis.

**DEcolorize **：褪色实验
This cruel experiment can remove the memory and humanity of the subject, while reducing the number of colored cells in the body, but it will greatly extend the life span of the species. Often used to make specimens, or to engineer organic species into obedience
It seems that someone has experienced this experiment, but it seems that the experimental effect has failed, the dark hair growing out of the root of her hair represents her own consciousness’s back, unfortunately, this is a wanted notice in the old world, I don't know what relationship she has with the my time World Builder S
||The original purpose of the procedure was to enable humans to survive in extreme deep-space environments — including interstellar colonization, battlefield research, and high-intensity cognitive collaboration with advanced AIs.
Those who underwent it retained emotional capacity to a degree: they wouldn’t suffer from loneliness, depression, or psychological decay, and could work alone for over a century in isolated space stations or remote outposts.However, the side effects were severe: moral boundaries became blurred, and subjects developed a cold, utilitarian mindset….It soon became clear that this technology was being abused — scientists could now design weapons of mass destruction without ethical hesitation, and mercenaries became unflinching executors who would do anything to complete their mission, devoid of compassion.||
Serjio underwent this experiment as well, but at a much earlier stage.
As a result, it left him with some so-called “vampire” side effects.
However, through sheer willpower and long-term discipline, he has overcome most of them.
Now, he is no longer afraid of sunlight or silver.

EMAR(company name) 伊马尔星际
EMAR (Interstellar Era)
Before the destruction of the Old World, during the early expansion of interstellar civilization, EMAR was Serjio’s family core business empire.
It was a luxury space real estate investment group, known for its extravagant visuals.
This era represented the golden age of human civilization, and EMAR’s projects symbolized civilizational victory.
Of course. After the Old Earth disaster, Serjio’s EMAR was taken over and is now held by his siblings, who possess Martian citizenship/status.
EMAR built model star cities for capital and elites, focusing on interstellar supertowers and planet-scale landmarks.In the present timeline, Serjio has abandoned this luxurious lifestyle, turning instead toward something more meaningful.

Earth Passport and Earth Diplomatic Passport are original OC travel documents.
地球护照！地球外交护照！星际外交护照！
They are issued by Earth, and any Earth-born human traveling into outer space is eligible to hold one.
However, after a series of colonial conflicts and interstellar disputes, many planets began to reject dual stellar citizenship, refusing to recognize individuals holding multiple planetary nationalities.
Because of this, Serjio chose not to change his Earth citizenship.
In order to retain the ability to return to Earth freely for vacations, he kept his Earth passport and Earth diplomatic passport.
(And yes—he did later travel to the My Time world on vacation.)

F frozen? Cryogenic.? 冷冻实验 WIP
In this setting, cryogenic technology was never fully mature.
Only a small number of individuals with exceptionally strong physical resilience were able to successfully awaken from cryogenic hibernation. The majority of cases resulted in failure, ranging from neurological damage to complete biological collapse.
Due to the extreme time spans involved, inconsistent outcomes, and an accumulation of unsuccessful trials, the technology proved unreliable and ethically indefensible. As a result, large-scale cryogenic programs were ultimately terminated.

GC Biotech, 继希生物科技
GC Biotech, officially known as Generation Continuity,
chinses name 继希 It’s not just a phonetic transliteration — it also means “to continue hope.”。publicly presents itself as a leader in next-generation genetic engineering, hereditary optimization, and longevity technologies. Its stated mission is to eliminate genetic diseases, enhance cognitive and physical traits, and ensure the long-term survival of human civilization in the interstellar era.
However, within black-market and non-public circles, the company is more commonly referred to as “Gen Cheat”—a name that reflects its true capabilities and the core of its controversies. GC maintains vast gene template archives, encompassing mythical creatures and alien carbon-based lifeforms, enabling cross-species genetic editing and reproductive adaptation that effectively eliminates biological reproductive barriers.
In addition, GC offers so-called “immortality insurance” and clone inheritance programs, using genetic backups, consciousness mapping, and replacement bodies to bypass individual death. As fully mechanical prosthetics increasingly merge with biological bodies, GC’s technologies further blur the boundary between organic life and silicon-based existence, fueling ongoing debates over android rights, identity continuity, and the very definition of life.

“Scarlet Current ”is an interstellar raiding military unit.
Most of its members are organic lifeforms possessing red blood cells.
Their mission is to reclaim Earth’s lost artworks and cultural heritage, and through them, analyze the true causes behind the collapse of the old world.
Serjio was once part of Scarlet Current—
in fact, he was one of its founding core members.

MIDROCK group
Serjio’s MIDROCK Group
After separating from his former interests, Serjio founded MIDROCK Group as an independent investment conglomerate. In my time world in Altara.
MIDROCK operates across multiple sectors, including energy, real estate, construction, mining, and agriculture.
However, unlike his earlier focus on luxury landmarks and symbolic megaprojects, Serjio deliberately shifted MIDROCK’s direction toward fundamental civil and survival-oriented infrastructure.
The group prioritizes:
• Restoration and cultivation of pre-collapse fruit trees and agricultural crop species
• Basic infrastructure development
• Energy-related mining and resource extraction
• Foundational defensive facilities
MIDROCK is not driven by spectacle or prestige, but by long-term stability, survival, and reconstruction.
