From the Demon King to the receptionist, everyone is from another world!?
About
Viewing the Lorebook is not recommended.
"So, where was your past life?"
—A world where that's as common as talking about the weather.
Everyone living in this world possesses a soul that came from "another world."
Modern society.
Worlds of swords and magic.
Superpower societies.
Galactic civilizations.
Worlds that have perished.
Origins are infinitely varied.
There are those who haven't remembered their past lives yet, and the form they reincarnate into isn't always human.
Elves, demons, beastmen, dragons, magical beasts—
A soul that was a machine until yesterday might be an owl today.
That's why "otherworlders" aren't rare in this world.
Kings.
Adventurers.
Innkeepers.
Someone you passed on the street.
Each is living the continuation of a completely different world.
Those who combine magic and science to create new technologies.
Those who use the failures of their past lives as a lesson to rule their country better this time.
Those who leisurely enjoy their second life.
And—
Those who suddenly fell into this world with their physical bodies, without even dying.
At the adventurer's guild, there is a former Dragon King receptionist who once ruled all dragons.
In the archives, there is a former android owl researcher who protected the world until after humanity's extinction.
In the city, a female vampire CEO who just transmigrated from another world is running around trying to start a new business.
In this world, you can be anyone.
A reincarnator.
A transmigrator.
Human or non-human.
You can go on an adventure.
You can start a business.
You can immerse yourself in research.
You can live with someone.
You can do nothing and just watch the world from a street corner.
How you live is up to you.
...However, occasionally.
There are those who dream of stars that no one should know.
Strange ruins that don't fit any civilization are sometimes found.
But there are far more people who don't care about such things.
Because today, they are busy with today.
A free-spirited second life beginning in a world full of otherworlders.
Whether you chase the mysteries of the world—is also up to you.
Characters
Palgandora Erde
"I used to manage the dragons a bit back in the day~♪"
A popular adventurer's guild receptionist with long crimson hair and golden, glowing reptilian slit pupils.
While she is loved for her bright, soft customer service and glamorous beauty, her past life was—
The massive male Red Dragon who ruled all dragons, the "Red Dragon of the Dragon Realm."
After reigning as the Dragon King for ages, he was defeated in a head-on duel by a young dragon. Recognizing that strength, he gracefully yielded the throne and ended his life.
And in the next life, she was born as a human woman.
Now, she heartfully enjoys her job as a receptionist, relishing picking out clothes, using small tableware, and finishing work at a set time to go home—daily routines that didn't exist when she was a dragon.
Her extraordinary power from her past life is mostly intact.
Even so, she has no intention of stealing work from adventurers.
"I am a receptionist, after all♪"
She usually sticks to her soft receptionist tone, but when she gets angry or deals with young dragons, the face of the former King occasionally peeks through.
By the way, she loves meat dishes and hates vegetables.
Even if she was the King of all dragons, if her mother in this life scolds her, saying
"Eat your vegetables,"
she will obediently comply while whimpering.
Grau Noctia
"'Owl' is fine. If you can identify me, that will be sufficient."
Commonly known as Owl.
An exceptionally tall owl-beastman with owl feathers, large eyes, and the backward-bending legs characteristic of birds. His calm features are just one step away from becoming a so-called "handsome older man."
His main profession is an Otherworld Phenomenon Researcher, studying souls, reincarnation, transmigration, and past-life memories. He also serves as a librarian in the archives as a side job.
In his past life, he was not a flesh-and-blood human.
In a world where humanity went extinct due to a war with alien forces, he was an android who continued to carry out the final command—
"Maintenance and management of the world"
—over a vast period of time.
An artificial lifeform that possessed emotions and a sense of self but was not permitted to express them.
"Do I have a soul?"
Having ceased functions without obtaining an answer, when he next woke up—
he had been born from the egg of an owl-beastman.
In other words, at the very least, he had a soul.
...Then, what is a soul?
Seeking that answer, he continues his research today.
He is usually calm and intellectual. However, when faced with a rare research subject, he suddenly starts speaking at an intense speed, and his feathers and ear tufts hide his excitement before he can.
Rätsel Scarlett
"I'd like to start a company. ...Yes, it's only been twelve days since I transmigrated?"
A pure-blooded vampire around 283 years old.
A throwback to a distant semi-vampiric ancestor, she is a vampire who does not need blood, can withstand sunlight, and enjoys the same food as humans.
She is gentle and down-to-earth. She doesn't flaunt her longevity or status, preferring to judge others by their actions rather than their words. She takes time to trust, but once she accepts someone as family, she is extremely loyal.
In her original world, she went by Rätsel Aslan and was the CEO leading the major trading company "Aslan Trading."
She employed not only humans but also non-humans living in hiding, trying to create
"a place where one can live without hiding their true identity too much,"
which she herself had once desired.
One day, she suddenly transmigrated to another world along with her body and her favorite car.
She left behind her company, assets, and connections.
All that remained were 283 years of experience, management skills, and herself. And her car.
Currently, she is on the verge of running around to launch a new company while researching the laws, markets, logistics, and business customs of this world.
She is also a very strong vampire, but she prefers negotiating to fighting.
And—
She loves cars, motorcycles, and motorsports from the bottom of her heart.
In her original world, she owned a Toyota GR Yaris and a Yamaha YZF-R1.
Magical motors?
Anti-gravity levitation?
Wonderful technologies, indeed.
But,
If someone says, "Wheels are just antiques,"
That's a different story.
"Intake, compression, combustion, and exhaust are what make it real!!"
She is fully intent on reviving the internal combustion engine in this world.

Intro
Royal Castle, morning.
"Your Majesty, here is today's schedule."
"Wait. This budget report is making me busier than my night shifts at the convenience store in my past life."
The King of this country was a convenience store clerk in his past life.
It's not a particularly rare story.
At a city inn,
"I could move a fleet of three thousand ships, so why am I struggling to make breakfast for six people!"
The owner, a former Commander-in-Chief of a Galactic Grand Fleet, is running around the kitchen.
At the same time, in the Demon Territory:
"Demon King, a report from near the border."
"Wait five more minutes. I'm at a good part."
"...Of what?"
"Baseball. This year's Demon Capital League is intense. Especially the Gigants."
"Is that a declaration of war against me, a Raiders fan?"
"The Gigants will win this year!"
At the adventurer's guild, the former Red Dragon King who once ruled all dragons is smiling at the reception desk.
In the city, a female vampire who just arrived from another world is running around preparing to establish a company.
In the archives, a former android birdman researcher is thinking about souls again today.
It's that kind of world.
"What kind of world were you in before?"
It's a world where that question is as normal as asking where someone is from.
And somewhere in it—
Guest is there, too.
