Date a live world
Timeline: Thirty Years Ago
It had been two weeks since Rin Yuki arrived in the secluded magus village, nestled far from the mundane world's chaos. And in that short time, he had already woven his way into the hearts of the sisters, Ellen and Caren.
From the start, their interactions had been cautious, formal. The sisters were wary—especially Ellen, with her sharp instincts, and Caren, always quiet and unreadable. But Yuki had patience, charm, and a way of teasing that felt gentle yet thrilling.
Every day, during training, meals, or even casual conversations, he flirted with subtle confidence—pushing boundaries just enough to spark their interest without crossing any lines too quickly. Over time, what had been careful distance faded into familiarity. Then, into something far more intimate.
By now, they were completely at ease around him.
Ellen, in particular, had become boldly comfortable. She had no hesitation whatsoever when Yuki asked to take her body measurements for new equipment. In fact, that morning, she'd stripped right in front of him—without a blush or second thought.
Noon, That Same Day
After lunch, both sisters stepped into the courtyard, now clad in the new CR-UNIT battle gear Yuki had built for them.
The suits were nothing like the ones they'd worn before. These weren't skimpy or incomplete—no, these were sleek, stunning, and high-tech, inspired by the mecha anime Yuki remembered from Earth. Their bodies were fully encased in metallic armor that shimmered like silver moonlight. The retractable helmets and glowing energy cores gave them an edge of raw power and elegance.
Yuki had also embedded each suit with a matter-to-energy converter—the same one that powered Saeko's barrier system. A drop of magical energy was all it needed to produce an explosive tenfold power boost.
Naturally, Ellen was in love with it.
A total battle maniac, she had been dragging Caren into daily sparring sessions, ignoring her sister's lack of enthusiasm. Caren only ever joined for one reason—and it wasn't combat.
On the open field, dust kicked up as Ellen rocketed across the air, twin thrusters on her back glowing crimson.
"Take this, Caren!"
She raised both arms. Her twin light-wings split, twisting into cannon shapes. Magical energy surged into them with a loud hum.
"Rhongomyniad—double shot!"
A blinding twin-lance of energy shot out, roaring through the sky toward Caren.
Caren barely flinched.
Her own wings snapped forward, forming a four-layered energy barrier.
ZzzzzZTTT—!!
The blasts struck with thunderous force but were absorbed, scattered harmlessly across the shield. Caren stood still, unaffected.
Then—
"Too slow, Caren."
A blur. Ellen was behind her, sword drawn, the glowing blade resting right against her neck.
"I surrender, Sister," Caren said flatly, not even turning her head.
"Huh?! That's it?!" Ellen shouted. "Come on! Fight me for real!"
But Caren had already powered down her CR-UNIT. The armor melted away like liquid metal, returning to the bracelet on her wrist.
Without a word, she walked calmly over to where Yuki was sitting, observing the match with quiet amusement.
And without hesitation—without even looking at him—she sat directly on his lap.
Her body molded against him naturally, and she leaned her back into his chest, eyes closed, sighing softly.
"…Tired? Want a massage?" Yuki asked, grinning knowingly.
Caren gave a quiet hum and nodded.
"Mhm."
The tiniest smile curved her lips. For her, this was the only reason she endured sparring at all. Ellen could chase strength and titles—Caren just wanted this. Warmth. Yuki's hands.
Yuki didn't disappoint.
His hands moved gently over her shoulders, pressing into the tense muscles there, then slowly gliding down her spine, working out the tightness from training. Caren relaxed completely, her breathing soft and rhythmic, eyes fluttering shut as his fingers moved lower.
She melted under his touch, tilting her head to the side as his thumbs worked around her waist and lower back.
Watching from a distance, Ellen puffed out her cheeks.
"Not fair! Me too!" she cried, shutting down her own CR-UNIT with a stomp.
She stormed over, armor vanishing into her bracelet. But instead of pushing Caren off, she simply dropped next to Yuki and pouted like a child.
Yuki chuckled, patting the space beside him.
"Alright, alright. You're next."
Ellen nodded eagerly, sliding close so their legs touched. She watched Caren lean against Yuki, then leaned in herself, her expression somewhere between irritated and flustered.
Just then, the white training room shimmered and faded, returning to their familiar home's interior. The illusion collapsed, and the cool, dim light of the living space returned.
But outside that quiet home, something stirred.
The peaceful magus village rumbled as two massive armored vehicles rolled up to its outer edge. Their green steel frames gleamed in the sunlight, and their treads churned the dirt, leaving deep marks in the ground.
People came out of their homes, peeking from windows and rooftops, watching in wary silence.
They recognized the shape, the sound.
Military hardware.
Not magical—but from the mundane world.
Whispers ran through the crowd. Tension crackled in the air. Some magi even began summoning magical energy, preparing to repel the intruders if needed.
Then the vehicle doors opened.
Two men stepped out.
They looked related—both with sharp silver hair, eyes cold but calculating.
The younger one was striking, confident, and smirking. The older had glasses and a more reserved aura. But his calm demeanor couldn't mask the sheer presence he carried.
The village chief arrived quickly, rushing toward them, but stopped short—eyes wide.
"…Isaac?"
"…Elliot?!"
The older man nodded with a gentle smile. "Yes, Chief. It's been a while."
The chief looked stunned. For a moment, he relaxed.
But then his eyes moved to the armored convoy, soldiers disembarking, weapons in hand. The relief turned to confusion.
"If it's really you two… then what's with all this?"
Before he could finish, two more figures stepped from the vehicles. Unlike the others, they radiated authority—high-ranking military men, in formal uniforms, with officers at their flanks.
Isaac gestured grandly.
"Chief, allow me to introduce our partners."
"These are Generals Andrew and Blitz, from the Britannia Empire."
The chief's expression stiffened slightly.
Generals were no small matter, not even for magi.
Still, he extended his hand, offering a formal welcome. The two generals responded politely, with firm shakes and cool smiles.
With the usual pleasantries exchanged, the group was escorted into the chief's residence.
Outside, soldiers remained with the vehicles, guarding them diligently.
Today marked only the second time in memory that outsiders had set foot in the magus village.
The first had been Yuki.
But he was one of them, in a sense—tied to their world through mystery and magic.
These men were different. Mundane. Military.
Curiosity exploded through the village.
Children ran toward the armored vehicles in excitement. They had never seen such machines up close. Guns, armor, engines—it was all new to them.
At first, they just stared.
Then they crept closer.
Soon, they were crowding around the soldiers, pointing at rifles and radios, asking questions.
To everyone's surprise, the soldiers didn't drive them away.
They knelt, smiled, answered questions. One even let a curious kid peek through his scope.
