The heavy rain poured over Tokyo, drowning the streets in cold, muddy puddles. In the corner of a narrow alley, a man in a worn-out coat and hole-ridden shoes leaned against the damp brick wall. Haruto Kamiyama, who once was a hopeful 27-year-old, now was merely a shadow of his former self. His black hair was messy, and his once-handsome face bore small scars from life on the streets.
"This isn't living… this is hell," Haruto muttered, staring at his empty hands. Just a few months ago, he was an ambitious young man who had invested all his savings into a tech startup project. But what had promised to be a golden opportunity turned out to be a scam. His money was gone, his debts piled up, and the friends who once admired him no longer answered his calls.
Haruto let out a bitter laugh. Even he found his stupidity amusing. He had no home, no job, and no family who cared about him anymore. In his pocket was only an old phone, the last thing he hadn't sold for a meal.
That night, Haruto turned on his phone to kill some time. The cracked screen lit up, showing an old wallpaper that only brought pain—a picture of him smiling with a woman who had long since left him. With a heavy sigh, he tried opening a social media app, but there were no notifications. No messages. No one cared.
Suddenly, his phone screen flickered strangely.
"Huh?" Haruto stared at the screen, frowning. A new icon appeared with bold text: Ero Gacha. The icon looked like a pink slot machine adorned with hearts and shimmering gold.
"What the hell is this?" he muttered, tapping on the icon.
As soon as he touched it, the screen turned black for a moment, then a flashy animation appeared. A sweet, feminine voice played from the phone's speaker.
"Welcome to Ero Gacha! Spin now and change your life!"
Haruto froze. "Ero... Gacha?" Just saying the name made his face flush slightly. "What kind of pervy app is this?"
On the screen, a large, sparkling button with "Spin Now" written on it gleamed like a jewel. Haruto shook his head. "Who even makes something this ridiculous?"
But curiosity overrode his logic. After all, what else did he have? He had nothing left to lose. With a wry grin, he tapped the button.
The digital slot machine on the screen started spinning, flashing images rapidly: beautiful women, strange objects, even exotic backdrops. Haruto squinted, trying to follow what was happening, but before he could make sense of it, the machine stopped.
"Congratulations! You've won an SSR Prize: Liliya, Succubus Queen!"
"Wha... What?!" Haruto yelped. His phone's screen glowed brightly, so brightly that it blinded him. He dropped the phone to the ground, but the light only grew stronger until the entire alley was bathed in a striking pink hue.
Suddenly, in front of him, a woman appeared from the light. Her long, fiery red hair flowed down her back, and her amethyst-colored eyes sparkled like gemstones. Her figure was perfect, like a goddess sculpted from marble, draped in barely-there clothing that teased more than it covered. Two small horns adorned her head, and a long tail with a heart-shaped tip swayed gently behind her.
"Hmm... So you're the one who summoned me?" The woman smiled, her voice sweet and seductive like an intoxicating melody.
Haruto froze. His mouth hung open, but no words came out. His brain struggled to process what he was seeing. Was this a dream? Had he gone insane?
The woman stepped closer, leaning down so her face was directly in front of Haruto's. A sweet, intoxicating fragrance filled the air around her. "You can call me Liliya," she said, touching Haruto's chin with her finger. "From now on, I'm yours, Master Haruto."
Haruto swallowed hard, his eyes locked on the woman—or rather, the creature—in front of him. Liliya. The name echoed in his mind like a spell that couldn't be erased.
"Who... are you?" Haruto finally managed to stammer. His voice was filled with nervousness, yet there was an odd tingle of excitement—Liliya's overwhelming aura made his heart pound.
Liliya gave a faint smile, revealing tiny, sharp fangs. "I already told you. I'm Liliya, the Succubus Queen, your first prize from Ero Gacha," she replied softly, her tone dripping with allure. She ran her fingers lightly over his chest, as if assessing him. "Hmm, your body is... fragile. But don't worry, we can fix that."
"A prize? From... gacha?" Haruto glanced at his phone, now lying on the ground. Its screen displayed a message:
Congratulations! Prize claimed.
The text blinked for a moment before disappearing.
"Exactly," Liliya answered, stepping back. With a snap of her fingers, an extravagant golden throne appeared out of nowhere. She sat gracefully, crossing her legs and looking at Haruto like a queen sizing up her subject. "You've been chosen by an absolute force to wield Ero Gacha."
"Why me?" he finally asked, his voice trembling between curiosity and fear. "Why was I chosen? I'm nobody."
Liliya chuckled softly, covering her mouth with her delicate hand. "Because Ero Gacha doesn't choose based on bravery, intelligence, or even wealth. You, Haruto Kamiyama, are just a random person the system picked... based on luck. And this time, luck is truly on your side."
"So... I was chosen randomly?" Haruto muttered, almost laughing to himself. "Sounds just like my life."
Liliya giggled. "Oh, don't be so hard on yourself, my dear Master."
Haruto was still confused, but something about her words warmed his chest slightly—was it hope? Or just the effect of her calming aura? "So... what do you want from me?"
"From you? Nothing," Liliya replied with a sweet but dangerous smile. "I'm here to serve you. Succubi like me exist to fulfill our master's desires." She stood from the throne, walking closer to Haruto again. "Whatever you want... just say it."
Her words made Haruto's heart skip a beat. "Anything?" he asked, his voice trembling.
Liliya nodded slowly. "Anything," she repeated, each syllable oozing sensual emphasis.
Haruto took a step back. He couldn't tell if this was a nightmare or some twisted dream.
He picked up his phone and saw a notification.
"Congratulations! You've used your first Free Spin. For additional spins, please use Ero Points."
"What are Ero Points?" Haruto frowned at the screen, noticing a gold coin icon marked EP at the corner.
Liliya chuckled, sitting gracefully on a sofa that appeared out of thin air. "Ah, I forgot to mention. Ero Gacha gives one free spin to start, but for the next ones, you'll need Ero Points, or EP. That's the currency for spinning this gacha."
"And... how do I earn these points?" Haruto asked, staring at the screen, which showed a balance of 0 EP.
Liliya leaned forward slightly, her gaze sharp yet playful. "Ero Points can be earned in one main way: through satisfying actions... and utilizing your prizes."
"Satisfying actions?" Haruto echoed blankly.
"Think more creatively, Master," Liliya teased. "This is Ero Gacha, after all. The more you engage emotionally or physically with your prizes or any women, the more Ero Points you'll gather."
Haruto's face turned red. "So you're saying I need to... do that things to earn points?"
"Exactly," Liliya confirmed with a mischievous smile. "No need to be shy. This system is made for pleasure. Besides..." Liliya stepped closer, her voice dropping to a seductive whisper. "You have me as your first prize and your woman. Why not start with me?"
