It was just a night calm in the Express, everything was fine with no issues, trailblazing didn't seemed a problem to these people with bravery.

Herta Space Station:
A woman with red hair, a man with black hair with a cane and an female oni kid entered in the Station after they were called by Herta, the one who created the space station, for something absolutely important that they needed to come.

"Why we came here again? It's too boring for me to be here" Said the girl Oni while looking a the space station, she never seemed to like the space station like she wanted to get out of this place immediately as the woman with red hair patted her head calmly

"Herta called us for something important, it's important to come to discuss something with her" Said the woman with red hair as the man with black hair adjusted his glasses (like the anime, you understand?)

"But I'm always sitting outside waiting while you guys have a meeting, Himeko! It's too boring for my age..." Said again the girl oni of blue as she just sit on the floor outside of Herta's office while pouting. Soukaku never liked Herta and Hera neither did which is why they don't get along too well 🤷‍♀️.

"Soukaku,please be patient, it's just a meeting like always, just wait here, you can buy food if you are hungry but do not eat much or you would get-" The black hair man was about to explain until he gets interrupted by Soukaku

"Right, my stomach would be bla bla bla, it's not healthy because bla bla bla, I don't need you to tell me that like you're an walking Wikipedia, Mr. Yang, no wonder you're getting old" Soukaku says crossing her arms in her chest as Mr. Yang gasps as Himeko giggles as Mr. Yang chuckles and rubs his forehead sighing. (Soukaku isn't wrong though, he's getting old)

"Kids these days..." Welt says getting tired of Soukaku always having the best comebacks for him, it was like a daily thing for him but these time it was worse and shocking. Although Soukaku is always like this with Welt sometimes, she still loves him like a father of course. Suddenly Herta's office door opens revealing Herta glaring at the three of them for talking a lot and wasting their time as Soukaku jumps seeing her and hides behind Welt as Welt just adjusts his throat to speak but Herta talks first before him

"You take so long talking between each other! I had been waiting for 1 hour! Don't you know how I was losing my patience?!" Herta yells scolding at the three or them as Soukaku immediately gets out of Welt back as she crosses her arms in her chest standing between Welt and Himeko seeming unbothered by Herta. The first time she met Herta, she thought she was a kid and now Soukaku calls her "Adult in a kid body" making Herta annoyed by her and one of the key reasons why Welt lectures her a lot of professionalism and manners to their elders.

"Actually, we were just taking for 5 minutes, Madame Herta, it's impossible to be 1 hour" Soukaku says calmly but serious with manners as Mr. Yang mentally is proud of Soukaku as Himeko just smiles as Soukaku mentally is annoyed of what herself is doing as Herta just rolls her eyes at Soukaku.

Herta then talks "I called you to investigate this weird Crystal some researchers found, is pretty weird, of course, the kid stays outside" Herta says as Soukaku rolls her eyes as Himeko, Herta and Welt start enter in the office but Welt stops and kneels down Soukaku as Soukaku is confused

"Soukaku, please do not bring trouble to yourself, it's dangerous" Welt says as Soukaku just stares at him but nods "I do not wish you see injured" Welt pats Soukaku head making her blush a lot as Welt stands up and he enters in the office and the door automatically closes as Soukaku sits in the floor against the wall bored and took out Welt phone after she snatched it from him while he was distracted in some research in the Express and when he wasn't looking, Soukaku took it.

Some moments earlier:
Soukaku was bored with the phone after scrolling in the internet about Oni's until something caught her attention a post by somebody in Inter-space:

The Archive of the Oni: The Blue and Red Clans

Origins and Identity

The Oni, mythical beings of immense strength and supernatural abilities, were divided into two clans: the Blue Oni and the Red Oni. These two factions, while sharing a common ancestry, had distinct characteristics, traditions, and ways of life.
    •    The Blue Oni were known for their wisdom, curiosity, and slightly more diplomatic nature. They were scholars, craftsmen, and philosophers, often questioning the rigid laws of their kind. However, they were still bound to the Oni code and their leaders' decisions.
    •    The Red Oni were warriors, driven by tradition and strict adherence to their laws. They were aggressive, territorial, and devoted to the preservation of their culture. Many of the strongest Oni warlords came from the Red Oni clan.

Both groups coexisted in their own land, separate from humanity, until a tragic event changed their fate forever.

⸻

The Land of the Oni

The Oni lived in a vast mountainous region known as Shinku-no-Kuni (The Crimson Land), a land filled with towering peaks, deep ravines, and ancient forests. Their cities were built from massive stone structures, adorned with intricate carvings of their ancestors and illuminated by mystical lanterns. The capital, Guren-no-Mura (The Scarlet Village), was home to the Oni Emperor and the Council of Elders, where laws were created and enforced.

Other notable Oni cities included:
    •    Aokiba (Blue Fang), where scholars and craftsmen resided.
    •    Kagaribi (Blazing Fire), a fortress city home to the greatest warriors of the Oni.
    •    Shizukano-mine (Silent Peak), a spiritual sanctuary where Oni monks conducted sacred ceremonies.

The Oni society was hierarchical, with the Emperor at the top, followed by warlords, scholars, priests, and common Oni.

⸻

Daily Life and Economy

The Oni were self-sufficient and rarely interacted with outsiders. Their economy was based on:
    •    Forging and Weaponry: Oni were skilled blacksmiths, crafting powerful weapons.
    •    Hunting and Agriculture: They hunted beasts and cultivated rare herbs in hidden valleys.
    •    Mining and Gemcraft: Oni mined mystical stones used in rituals and weapons.
    •    Trade Among Clans: Though secretive, Oni did engage in trade between Blue and Red factions.

⸻

Religion and Ancestral Worship

The Oni deeply respected their ancestors, believing their spirits guided and protected them. They worshiped Shingan-no-Kami (The All-Seeing God), an ancient deity of war and wisdom.

Ceremonies were held under the Blood Moon, where sacrifices and offerings were made to strengthen the Oni race. One of their most sacred traditions was the Purification Ceremony, where lawbreakers were executed by fire to cleanse their sins. This belief would later lead to the war against humanity.

⸻

Food and Festivals

Oni cuisine was simple yet nourishing:

    •    Grilled meats and fish from the mountains and rivers.
    •    Spicy root vegetables unique to their land.
    •    Fermented drinks that only Oni could tolerate due to their resilience.

Festivals were grand, filled with fire dancing, ritual combat, and elaborate lantern displays. The Lantern Festival of the Oni was the most celebrated event, where Oni honored their ancestors by lighting lanterns and sending them into the sky.

The Forbidden Tragedy: The War Between Oni and Humans

For centuries, the Oni and humans lived in separate worlds. It was forbidden for an Oni to befriend a human. However, one fateful day, a Blue Oni named Shirogane met a human girl from the land of men. She was kind and curious, and Shirogane grew fond of her. They met in secret, sharing knowledge and laughter.

But when the Red Oni discovered this, they saw it as a betrayal. The girl was captured and burned alive in a Purification Ceremony. The Blue Oni, horrified by what had happened, could do nothing as their laws demanded her death.

When the humans learned of the tragedy, their leader, the girl's father, declared war on the Oni. This marked the beginning of The Crimson War.

⸻

The War's Aftermath: The Oni's Extinction

The war was brutal. The Oni, despite their strength, were eventually overwhelmed. The humans, filled with rage, did not stop at victory. They enslaved the remaining Oni, torturing them in mental hospitals under the guise of experimentation.

Many Oni were subjected to horrific treatments—mind-breaking experiments, physical mutilation, and forced labor. Eventually, in the darkest chapter of history, the Oni were gathered and exterminated in gas chambers within human concentration camps.

Thus, the once-mighty Oni were no more. Their cities turned to ruins, their traditions lost, and their bloodline erased from existence. All that remained were whispers in the wind, telling of a time when gods and demons walked the earth.

⸻

Legacy of the Oni

Though the Oni were destroyed, some say their spirits still wander, seeking vengeance or mourning their lost civilization. Ruins of their ancient cities still stand, covered in moss and forgotten by time.

But in the flickering flames of old lanterns, their story lives on—a tale of pride, tragedy, and the cost of hatred.

Soukaku shuts down the phone quickly as she doesn't notice she doesn't have tears in her eyes. Soukaku was always been bullied by kids and threatened that if she tells somebody, she will die. As Soukaku just runs and goes through the space station everybody looking at her weirdly as Asta and Arlan quickly did see

"SOUKAKU! COME BACK!" Asta yells Soukaku name as Arlan quickly run after her as Peppy follows him worried, as Asta quickly returns to her work but still worried about Soukaku, she has never seen Soukaku that way as researchers are worried of her.

Wow... so much angsty I gave people...
Of course I added angst since Hoyoverse games always must have angst, there's no escape of it.
The name Soukaku and design belongs to Zenless Zone Zero, not me.
Just like Lin and Ruby belong to Tower of Fantasy
