I skipped checking my lifeline harness.
That's all. Yet the foreman came and started yelling at me like crazy.
"You idiot! The rules are there to protect you!"
Hmph, as if. Those rules were made by the construction company to protect themselves. Hypocrites!
Annoyed, I cut a hole in the foreman's harness. Then he fell off the scaffolding and smashed into the ground, squishing like a tomato.
Heh heh.
Hahaha.
I'm not the bad guy here.
My old man was locked up in a pigsty of a prison, and my old woman hung herself, all because of rules made by hypocrites like that foreman. Now I'm being chased by debt collectors, can't go to school, living a trashy life, and scraping by doing jobs I hate just to get by day to day.
Life is nothing but a cesspool of shit worse than vomit. So what? If I'm just scum like this, shouldn't I be free to do whatever the hell I want?
That's what I was thinking, but when the flattened foreman crawled all the way to my house, I was seriously spooked.
"Would you like to become a demon, Kamino-san?"
And to top it off, a demon possessing a corpse is recruiting me? Seriously?!
His name was Kamina, a Japanese man of twenty years. Despite his youth, his forehead was crisscrossed with wrinkles, and his eyes glimmered with a crude light.
Kamina worked at a karaoke bar, waiting for the perfect sacrificial offering worthy of his greatest opportunity.
Then, on a winter day when the wind howled and the sun had sunk below the horizon, they arrived.
"Welcome! Please write your names and ages here."
"...Yes."
The one who answered was Nakano Miku. Her companion was Nakano Yotsuba, also eighteen. They were clearly sisters.
Wait, are they twins?
Though their hairstyles differed—Yotsuba had a bob cut, while Miku had a semi-long hairstyle—their faces and heights were identical. The only other way to tell them apart was by their clothing.
But their cuteness was so overwhelming that such details didn't matter.
Long eyelashes framed clear, bright eyes, and cherry-red lips complemented their fair skin, creating an overall luminous appearance. Despite their natural, makeup-free look, they were so captivating that Kamina couldn't tear his gaze away... and they were clearly right up his alley.
Moreover, both sisters were well-developed. Even through their winter coats, their figure was strikingly evident. Just a few fleeting glances at them sent blood rushing south to Kamina's groin.
"How long will you be staying?"
"Until morning."
"Ah, unlimited time, then. The drink bar is complimentary, but it's 1,200 yen per person, paid in advance."
"...Oh, I'll put it on credit."
"Okay, thank you!"
And they were rich. The credit card they presented was black—a high-end card, no doubt. Just thinking about their spending power made Kamina's mouth water.
Heh heh, I'm on a roll...!
Well-developed, wealthy, and beautiful twin sisters who perfectly matched Kamina's type. With all these factors aligned, he couldn't ask for more.
They'd make perfect prey for the Demon App.
"Enjoy your stay~"
Kamina retreated to the back, clutching his phone, which housed the Demon App.
The demon that had inhabited the Foreman's corpse that day had given it to him.
"Hahaha... With this app, anyone can become a demon. Any human will bend to your will."
"Any human?"
"Exactly. What if you could manipulate at will... girls so blessed with beauty, love, and wealth that they seem favored by God himself?"
Girls favored by God. Kamina laughed. Girls whom God, who had never favored Kamina, had endowed with everything. The blood-soaked Foreman/demon cackled at the thought of controlling them.
So Kamina laughed too. He laughed in delight at this wonderful prospect and accepted the proffered phone.
"Wait at karaoke bar '○○,' and suitable prey will appear. I'm sure it'll be a fun party."
"This is quite the thorough service."
"Haha... Of course, there's a price to pay."
"What?"
"Your price is just one thing."
"Well? Don't drag it out."
"Hahahaha... Your lifespan. The more you use it, the more time you'll give Kamino-san to live..."
Kamina activated the Demon App. He felt something inside him slipping away, and on the screen, numbers began counting down:
70/90 → 69/90
But there was no problem. He was about to live a wonderful life.
He would play with those huge breasts to his heart's content, squeeze every last penny out of her, and pay off that irritating debt in one fell swoop.
He would take the beautiful girls God loved and turn them into fleshly vessels, rejoicing in urine and semen. He would turn them into slaves, dedicating their glorious lives solely to Kamina.
"Hah, hah! Hahahahahahaha!"
I entered their names—Miku and Yotsuba—and their faces immediately appeared on the screen. Then, their personal information started flowing in one after another: height, weight, bust-waist-hip measurements, detailed sexual history, even their innermost thoughts—every conceivable piece of information was displayed on the screen.
This was just one power of the app. Apparently, it could search for a person's soul by name and strip them completely naked.
Holy shit, this is insane...!
"Both of them are G-cup with 88 cm busts, 56 cm waists, and 84 cm hips... Heh heh heh!"
Seeing all this information that any guy would pounce on, I couldn't help but chuckle.
Perhaps because they were twins, their numbers were surprisingly identical. The only difference was body fat percentage, which was slightly higher for Miku. Maybe she's more of an indoor type?
Both sisters had zero sexual experience.
"Huh?! Hey, are those two still virgins? What a waste!"
The information was so shocking it made me laugh in spite of myself. I never imagined such beautiful sisters could be virgins.
These are the perfect marks...! They look like they've never even considered selling themselves...!
"Heh, heh-heh...!"
In the world I'd come from, women like this didn't exist—unattainable beauties. For such a high-class girl to be a virgin... Destiny sure has a way of pulling off the most elegant tricks.
My cock hardened. Agh, I want to fuck them so badly. My heart raced with the overwhelming good fortune as I scrolled through more information.
(...Huh?)
Name: Nakano Miku
Likes: Uesugi Futaro
Status: Heartbroken
Memo: Fuutarou, I wish you all the best. I'll take care of that troublesome Yotsuba who's causing you trouble.
Name: Nakano Yotsuba
Likes: Uesugi Futaro
Status: Confused
Memo: I'm so happy that Uesugi-san and I share mutual feelings. But how will Miku ever forgive me...?
"Uesugi Futaro... What the hell is this?"
These two sisters apparently fell for the same guy. One got rejected, while the other got confessed to.
Even the Demon App couldn't parse the intricate details of their romantic situation, but it was undoubtedly complicated.
"Whatever..."
I never cared about other people's lives in the first place. What matters is how these girls can serve my own life.
Kamina clicked on "Person I Like" and began editing the hearts of the two sisters.
Name: Nakano Miku
Person I Like: Kamina Uesugi Fuutarou
Status: New Romance
Memo: That shop assistant from earlier was so cool. The crease on his forehead looked like a samurai from the Sengoku period—so handsome! Maybe I can try a new romance, too...
Name: Nakano Yotsuba
Person I Like: Kamina Uesugi Fuutarou
Status: Confusion
Memo: That shop assistant earlier had such a creepy look in his eyes... But unlike Uesugi-san, he felt more like a man. What am I even thinking?!?
"...heh!"
Kamina couldn't help but chuckle. With a single tap, he'd become the "Person I Like" for two lovely high school sisters.
This was the Demon App. It rewrote people's hearts with ease, manipulating them at will.
"Heh, heh-heh-heh! Time for some fun!"
Kamina swaggered into the room where the two girls were supposed to be.
