The dark sky and blood-red moon looked eerily strange.
This was another space—a place called the Demon Realm.
The ruler of the Demon Realm was the Demon King.
Beneath him stood his second-in-command.
She was the Demon King's trusted aide, possessing immense power, magical talent, and breathtaking beauty—feared and admired by all.
Her name was Jahy.
A striking, mature woman with black skin, purple hair, and golden vertical pupils sat gracefully in a chair.
She radiated an aura of supreme authority.
Jahy wore black boots and shorts, while her upper body was draped in only two strips of cloth.
Even as the Demon Realm's second-in-command, she remained minimalistic in her attire.
The pair of cat ears perched on her head gave her, despite her regal presence, a touch of unexpected cuteness.
As Jahy sat, the castle suddenly shook.
But as the Demon Realm's formidable second-in-command, she remained unshaken by such a minor disturbance.
Instead, she glanced toward the door with interest.
Soon, her subordinates came running, panicked.
"Lord Jahy, save us!"
"She's coming!"
Moments later, a golden ball of light streaked into the room.
As the glow dissipated, a magical girl in a pink dress with golden hair appeared.
She fixed Jahy with a cold, unwavering gaze.
Seeing the magical girl kneel and stare, Jahy rose slowly from her chair, her voice dripping with contempt.
"What? Just a little girl."
She stepped forward, scolding her subordinates as she passed.
"You are utterly useless."
Jahy spread her demon wings, preparing for battle, and addressed the magical girl.
"The Demon Realm is no place for a little girl like you. Leave at once…"
She was issuing a pre-battle warning, ready to deal with the intruder in her usual way.
But the magical girl had no intention of following the rules.
She attacked during Jahy's warning, catching her completely off guard.
Before Jahy could react, the girl flew over her head, heading straight for her seat.
Behind the chair was a black cloth.
The cloth lifted, revealing a massive red crystal.
This crystal was the heart of the Demon Realm's magic, providing a constant flow of power to maintain the realm's stability.
Without hesitation, the magical girl struck the crystal with her wand.
The impact produced a dazzling light, and large cracks spread across the crystal.
It all happened too suddenly; Jahy could only watch.
It was too late to stop the attack.
With the crystal destroyed, the Demon Realm began to collapse.
The ground shook violently, and Jahy felt her magic draining rapidly.
Disoriented, the ground beneath her cracked, and she plunged into an invisible black abyss.
Jahy cried out in defiance as she fell.
"You have no honor!"
Gradually, her vision cleared. She found herself in a small river, the flowing water grounding her senses.
But Jahy, once a mature and regal woman, had lost her magic upon leaving the Demon Realm—and her body had shrunk.
She had become a small loli.
Her body felt fragile, and the magic that had once surged within her was now nearly gone.
Realizing this, she lifted her hand and wailed.
"What is happening?!"
······
Meanwhile, Tanaka Masao had just returned to Chiba from Tokyo after leaving Eriri's house.
Concerned about his recent weight loss, he decided to walk home.
He strolled leisurely, enjoying the scenery along the way.
Glancing at the clear river along the roadside, he thought to himself:
[The water is so clean—it doesn't look polluted at all. I could probably drink it. Maybe it's because Chiba is more rural than Tokyo, and the environment is better.]
As he pondered, he noticed a figure in the river.
Looking closer, he realized it was a child.
Being a caring person, he instinctively acted.
He rushed down the hillside, shouting:
"Little sister, don't be afraid! Big brother will save you!"
As he approached, he realized the river was very shallow—only ankle-deep.
The little girl kneeling in the water was fine.
Slightly embarrassed, Tanaka Masao slowed down.
[I didn't notice the river was so shallow. Should I just leave quietly?]
He decided not to leave. Something seemed off—the girl looked dazed, as if searching for something or troubled by an unexpected event.
"Little sister, you…"
Just as he prepared to approach, a shiny object on the ground caught his eye.
He bent down and picked it up: a necklace adorned with red gems, beautiful and striking.
"It looks valuable—what luck!"
For a moment, Tanaka Masao forgot about the strange little girl, focusing entirely on the gem.
Suddenly, a scream came from the river.
"What is this?!"
The scream startled him, nearly causing him to drop the necklace.
At that moment, Jahy realized someone else was nearby.
Turning her head, she saw a small, unassuming human figure.
But when she noticed the red-gem necklace in his hand, excitement flared.
As the core of the Demon Realm's magical power, the magic crystal was not to be touched by anyone.
This particular crystal had been entrusted to her for her excellent service and the Demon King's trust.
It was not just a symbol of honor—it was her only source of power now.
This tiny crystal was her last remaining magic, incredibly precious.
"Hey, human! Put down that magic stone—it belongs to me!"
Tanaka Masao looked at the little loli in the river, then at the necklace in his hand.
He realized the girl wore a simple outfit.
Such mature clothing was clearly not something a child could normally wear.
He guessed she might be cosplaying. The second dimension of this world differed from his past life, and he didn't know who she was portraying.
However, with terms like [Magic Stone] and [I], he assumed she was a little Lolita who had advanced to the second year of middle school early.
Thinking this, Tanaka Masao couldn't resist teasing her a little.
