Kamina Kenta had neglected to secure his safety harness, essential fall prevention gear designed to protect workers from accidents while operating at dangerous heights.
That's all it was. Yet, his boss wouldn't shut the hell up, screaming his lungs out.
"Idiot! The rules are there to protect you!"
'Yeah, right. Like hell they are!! Those rules were made to cover the company's ass, not mine. Hypocrite.'
Angered by his foreman's self-righteous act, Kamina had made a small hole in the foreman's harness. It wasn't long before the guy fell from the scaffolding and splattered like a crushed tomato.
"Ouchh."
"Hahaha." Kamina felt no guilt, he just laughed.
Because of rules created by hypocrites like his manager had destroyed Kamina's entire family.
His dad ended up in jail, and his mother had hanged herself a while later, and Kamina. He was stuck being hunted by loan sharks, unable to go to school, and scraping by with a shit job as a day laborer.
'Life was nothing but a pile of vomit and shit. And if that's all it was, why the hell shouldn't someone like me do whatever the fuck he wanted?'
That's what he thought—until the flattened corpse of his boss crawled its way to Kamina's house.
"Would you like to become a demon, Kamina-san?"
Yeah, Kamina heard that right. A demon had possessed the boss's corpse and was about to recruit him-------------
Kamina Kenta. A 20-year-old Japanese man who carried the weight of a life far harsher than his age should have allowed.
Exuding a raw intensity that made others think twice before crossing him. His sharp, piercing eyes burned with an untamed defiance, hinting at a soul that had been tested far too often and refused to break.
Though his rough exterior gave the impression of a hardened gangster, the truth was far more complex. Beneath the facade was a man who had clawed his way through the depths of despair, driven by a fierce will to survive and an unyielding hunger for something better. Kamina wasn't a hero, nor a villain—just a man shaped by the cruelty of the world, daring to carve his own path.
Now working at a karaoke bar, Kamina waited for the perfect sacrifice that could change his life forever.
It happened on a bitterly cold winter evening, just as the sun had sunk below the horizon.
That's when they walked in.
"Welcome~! Please write your name and age here~," Kamina greeted, his tone feigning politeness.
"…Alright."
The girl who answered was Miku Nakano. Her friend was Yotsuba Nakano. Both are 18 years old. At first glance, anyone could tell they were sisters.
'Probably even Twins?' Kamina thought.
Though their hairstyles differed, their faces and height were indistinguishable. Yotsuba's bob cut and Miku's semi-long hair, along with their outfits, were the only ways to tell them apart.
But Kamina didn't care about any of that, 'They were fucking gorgeous.' That's what was in his mind.
With long lashes framing their large, animated eyes, cherry blossom pink lips, and pale, flawless skin, they exuded an innocent charm. Despite their lack of makeup, they were so dazzling that Kamina couldn't look away. And they both perfectly matched his type.
Moreover, they were both well-developed. Even through their winter clothes, their curves stood out in all the right places. Kamina's gaze wandered, his eyes hungrily tracing their bodies. Blood rushed down his crotch, and he had to fight the urge to adjust himself right there.
"How long will you be staying?" Kamina asked, trying to sound casual.
"Until morning," Miku answered.
"Alright, free time then. It's 1,200 yen per person, including unlimited drinks. Payment is upfront," Kamina explained, his mind racing with ideas that were far from professional.
"...Oh, credit card, please," Miku said hesitantly, handing over a card.
"Yes, Thank you~!"
Then he noticed the card—a sleek black one. No doubt, it was a premium card meant for the rich. Just thinking about their wealth had him practically drooling.
'Hell yeah, today's my lucky day…!'
Rich, drop-dead gorgeous, well-endowed twin sisters who perfectly matched his preferences. There wasn't a single thing to complain about.
They were the perfect prey for his [Devil's App.]
"Please enjoy your stay," Kamina said with a polite bow, retreating to the back room.
There, he pulled out his smartphone, clutching the Devil's App tightly. This wasn't just any phone—it was the one given to him by the demon that had possessed his foreman's corpse…
--Back a little while--
"Hahaha... With this app, anyone can become a demon. You'll have the power to bend anyone to your will," the demon said.
"Anyone?" Kamina asked, skeptical but intrigued.
"Yes, anyone!! Imagine it: the most beautiful girls, blessed by God with beauty, love, and wealth, all under your control."
The demon, wearing the broken, bloodied face of his foreman, had grinned wickedly as he spoke.
That made Kamina laugh too. He grinned back, saying that it was a wonderful thing, and took the smartphone that was offered to him by the demon.
"Go to a karaoke bar called XX. Wait there, and you'll find prey worthy of your desires. I promise you, it'll be an unforgettable party."
"Damn, you're making it way too easy," Kamina remarked, narrowing his eyes.
"Hahaha... Of course, there is a price."
"Yeah? What's the catch?"
"Just one thing: your lifespan. The more you use it, the less time you'll have left to live."
'Hahaha, what do I have to lose, my life had been nothing but shit till now, so let's turn things around shall we!' Kamina thought smirking.
And now it began---
With the twins sitting just a room away, Kamina opened the Devil's App. As the screen lit up, he felt something slipping away from inside him. The app's interface began counting down silently.
70/90 → 69/90
He barely noticed but didn't give a fuck. 'Who cares? This is it. My life's finally about to get good.'
His thoughts raced with possibilities.
'I'll play with those big breasts to my heart's content, squeeze all the money out of them, and pay off that dreaded debt in no time.'
'God's most cherished beauties would be reduced to nothing but my obedient wives, moaning and begging to serve only me!! Their radiant lives would become nothing but vessels for my desires, shining only for my pleasure.'
A wicked grin spread across his face as he prepared to rewrite their destinies.
"Hahaha… HAHAHAHAHA!"
Kamina Kenta's laughter echoed as he entered the names Miku Nakano and Yotsuba Nakano into the app.
