Yandere Simulator Life

"Rough day, buddy?" A giant of a man, seated upon an astral throne in the void of the universe, boomed his voice into the cosmic silence surrounding us.

Stars swirled like obedient subjects, orbiting his form, and he gazed down at me with a flicker of amusement—and perhaps a hint of gloating.

I couldn't tell for sure.

As the wise Menace Parker once said, "I missed the part where that's my problem."

Don't care about details; just roll with it. That's how life should be.

Perhaps sensing my thoughts as clearly as an open book, the enormous figure let out a low chuckle that reverberated through the vast emptiness.

"Alright, buddy, enough with the jokes. Let's get to the point. I need something from you, and I'm sure you wouldn't want to stay stuck in this endless void for the rest of your life, would you? Especially since there's no heaven awaiting you after your death."

I took a deep breath, feeling a strange surge of courage as I spoke. "So, what exactly can I do for you… God?"

"Ah, it's God of Webnovel, if we're being specific," he corrected with a grin. "You see, I was once known as the most cultured deity to ever exist. And you're here, standing before me now, all thanks to your unyielding faith in the webnovel that consumed your reading list in your lifetime."

"Now then, let's dive into what I have in mind. Lately, the trend of 'Simulator Life' novels has been dominating the ranking lists in Webnovel. I want to elevate the concept, improve it, make it something far greater—but first, I need an experiment to test my ideas. You, my friend, are the perfect candidate to become the main character in the prototype of the novel I plan to create in the future."

"You could refuse, of course," he added with a mischievous glint in his eye. "And if that's your choice, I'll let Lucifer take you. He'd be more than happy to invite you into his party in hell."

I almost rolled my eyes at the thinly veiled threat and cleared my throat. "Ahem, God of Webnovel, I've been an admirer of webnovel for a long time now. I'd be honored to join your 'sect' and become a loyal follower of your cult. How could I possibly refuse such an opportunity? Count me in, Webnovel."

"That's the spirit!" he smirked approvingly. "Now, let's talk about your preferences. Which branch will you represent? The Harem Sect? Non-Harem Sect? Futanari Sect? Yuri Sect? Loli Sect? Or perhaps the MILF Sect?"

"None of those," I replied with a grin of my own. "There's no sect more appealing than the Yandere Sect, if you ask me. Though, if there's an opportunity to join the Man of Culture Sect, well… I'd gladly sign up for both."

The God of Webnovel nodded thoughtfully, an amused smile tugging at his lips. "Since you have a fondness for yanderes, let's see… Yes, I believe I have the perfect 'golden finger' just for you, buddy. Now go, and try not to die out there."

He murmured to himself, "Next up is a lolicon from the Loli Sect… Let's give him a Loli Simulator Life, shall we?"

"Ahem… When exactly can I expect to leave, God of Webnovel?" I coughed gently, as his intense gaze turned back to me.

"Ah, right! Almost forgot. Now, don't bother me again, lad." With a flick of his wrist, he dismissed me, and I felt myself dissolving from the void, hurtling forward into an unknown world.

[Welcome to the Yandere Simulator Life, Player!]

[Our program is finely tuned to match your preferences for the perfect yandere experience, creating a world where you will truly belong, bond deeply, and most importantly, grow ever closer with them.]

[Once you immerse yourself in the Yandere Simulator Life, we guarantee that even the aloof and unreachable waifu from your past life will transform into the ultimate yandere, wholeheartedly devoted to you. Now then, let the game begin!]

[Choose Your Yandere Waifu]

[1. Yuki Suou (Rosidhere)] [Difficulty: Easy]

[2. Arisu Sakayanagi (Classroom of the Elite)] [Difficulty: Very Easy]

[3. Kaguya Shinomiya (Kaguya-sama: Love is War)] [Difficulty: Hard]

[4. Hoshino Ruby (Oshi no Ko)] [Difficulty: Normal]

[5. Fujiwara Moe (Kaguya-sama: Love is War)] [Difficulty: Nightmare]

Hello, Yandere, why are there so few choices available?

[You'll unlock additional waifus once you complete a game with one of the girls listed here. To fully unlock new waifus, you must complete every route available, progressing through each girl's unique storyline to its bloody ended, intense conclusion, and achieve at least a true ending with them.]

So, I need to date and complete all five girls' routes before I can unlock more girls?

[Exactly, just like in a galgame! However, be cautious: one of the girls in your completed route will remember your choices and endings from previous worlds. Therefore, choose your path carefully when you start a new world line.]

[Remember, this isn't simply a simulator. It's a real world with galgame mechanics. Understood?]

Okay, I understand.

So, who should I choose?

It seems, in terms of difficulty, the easiest option is Arisu Sakayanagi.

Even I thought so, too. She's the weakest yandere on this list, after all.

And crippled.

Yeah, what could a girl with a disability possibly do to a normal, healthy guy when she's in a yandere outburst mode?

Plus, emotionally speaking, Arisu doesn't display the truly obsessive tendencies of the hardcore yanderes. Even in the original story, where Ayanokouji is surrounded by many girls, she never acted out in drastic ways.

Though, if anyone crosses her…they do suffer her quiet but thorough revenge.

Alright, I think I'll start with her.

[Congratulations, Player, you have chosen the Arisu Sakayanagi Route!]

[Let the game begin.]

Where am I?

Why am I wearing this lab-rat outfit?

I looked around the unfamiliar room, disoriented, before my gaze fixated on a girl with lilac hair, her smile playful as she looked directly at me.

Then it dawned on me—I was in the middle of a chess match with her.

I didn't know why or how I ended up here, and chess wasn't exactly my area of expertise.

[Your intelligence stats have increased.]

['Chess Proficiency Skill 10' has been unlocked.]

[Quest: Defeat Arisu Sakayanagi in this chess match to reveal her as a mere 'fake genius' in front of you.]

[Reward: Adoption into the Sakayanagi Household.]

[Failure: Endgame]

With the game seemingly bestowing me with the skills and intelligence required to defeat this young prodigy before me, it seemed impossible that I could lose.

And so, effortlessly enough, I checkmated her, cornering her king.

I maintained a blank expression throughout, from the first move to the last, and noticed I didn't feel as expressive in this new reality.

Maybe it was because of the traits the game promised me to secure the 'perfect yandere' partner it hinted at.

After all, in the canon, this girl seemed to have a penchant for men with stoic expressions, broken pasts, or dark secrets like Ayanokouji.

"Spencer-kun… Hah... As expected from someone who emerged from the White Room. You're the first boy, and likely the last, to have ever defeated me," she said with a soft chuckle, apparently unbothered by her loss.

I observed her with the same stoic expression, not particularly moved by the victory or the situation.

"Not much of a talker, are you?" she added with a sly grin. "Fufufu... We'll meet again soon, Spencer-kun. Farewell for now."

With that, she turned and walked away, her back facing me as she departed, humming an unknown tune and tapping her cane rhythmically against the floor.

So...

What's next?

[On the following day, you were unexpectedly adopted by the Sakayanagi Household, gaining a new family along with all the privileges and expectations that accompanied it.]

[Professor Ayanokouji congratulated you on your newfound freedom, while you noticed a brown-haired boy watching you with envy in his eyes. You paid him no mind and felt a surge of relief at leaving this wretch place behind, embracing the thought of a fresh beginning in a life free from these suffocating cages.]

[In this altered reality, Principal Sakayanagi became your adoptive father, and Arisu Sakayanagi was now your new sister. There wasn't much to say about your new life, except that your sister regularly dragged you into challenging chess matches.]

[Time and time again, you effortlessly defeated her, your sharpened intellect and keen chess skills far outmatching hers. The edge you possessed in the game seemed almost as if it were enchanted, granting you flawless victory every time.]

[Arisu, no matter how determined, simply couldn't match your advantage—unless, of course, she had a similar "cheat" on her side.]

[With each match won, you would console her by offering a lollipop, which you had conveniently ordered online. However, as you still lacked personal funds, you had borrowed money from Arisu herself to buy these treats, making her sigh and roll her eyes at your antics.]

[Over time, her initial irritation softened, and she grew more attached to you. Eventually, she found comfort in sitting on your lap, acting like an affectionate little sister to you. You enjoyed these moments, gently stroking her lilac hair and sharing the stories you'd always wanted to tell—stories you never had time to tell in your past life, where you were so busy that you had no time to tell them.]

[As days passed, your bond with Arisu developed into something beyond just a rivalry over chess.]

[She became increasingly possessive, demanding more and more of your time and attention, as though afraid she might lose you. She wanted you all to herself, as any potential yandere would, and your life became deeply intertwined with her whims and desires.]

[So, how do you feel about this new development, Player?]

[1. Keep a respectful distance and focus on your studies.]

[2. Take advantage of your sister's affection for you and indulge in taboo behavior.]

[3. Respect her wishes and devote time to her without needing to exploit her.]

I chose the third option.

After all, she was my sweet little sister in this new life; there was no need to have impure thoughts about her.

But… was it truly that simple?

[Arisu is delighted that you didn't turn her away and you showed restraint instead of taking advantage of her.]

[At first, her requests are modest and don't really push any boundaries—she only asks you to accompany her outside and to tell her more stories.]

[Yet, her requests don't end there. After we spend a lot of time together, her requests gradually become more intimate. She begins to express her desire for you to join her in the pool at our home and to help her by applying lotion on her exposed skin.]

[You hesitated for a moment but eventually agreed, keeping a neutral expression as your sister stood in a purple bikini, her smooth back exposed while you applied the lotion across every part of her body. You respectfully avoided touching any intimate areas, all the while maintaining a stoic, detached demeanor.]

[But that was just the beginning. She even insisted that you bathe with her, helping to rinse her off with water and wipe her down with a towel.]

[Resisting was harder than ever because Arisu seemed to delight in teasing you each time you bathed together—not just once, but repeatedly, as if testing the limits of your self-control.]

[Over time, your resolve began to waver, and you found yourself reluctantly obeying whenever she requested that you touch or wipe intimate areas.]

[Yet her flirtations only grew bolder, crossing the boundaries as she leaned dangerously close, her lips mere inches from yours.]

[What will you choose?]

[1. Accept her.]

[2. Accelerate things, crossing the line that shouldn't be crossed.]

[3. Chanting Amitabha and leave.]

Fine, if she wants to play this game, let's play.

Without further hesitation, I devour her lips, catching her off guard with my sudden assertiveness.

Yet, she responds with enthusiasm, wrapping her arms around me as I claim her mouth.

We kissed each other for far too long, much longer than was necessary, as Arisu began to pull away from me.

She stared at me with an infatuated expression, her eyes were scary and dark, her action also daring, as her hands begin to press against my erection, stroking it softly as I sit down on the stool.

"Fufufu... Thank you for the treat, brother."

By that moment, she had begun to give me my very first experience of a handjob, one that sent waves of pleasure coursing through me, leaving my mind entirely blank from the overwhelming sensation.

Her soft hand continued its steady, gentle stroking, fulfilling my every need as she massaged and tended to my arousal, gradually working me towards release.

Eventually, I climaxed, spilling into her warm palm.

With a captivating and seductive glint in her eyes, she brought her hand to her lips and licked it clean, savoring each moment of my semen.

Afterward, she gracefully picked up her towel, draping it around her bare form, while I watched her retreating figure, feeling utterly mesmerized and dazed.

[From that day onward, Arisu began sneaking into your room at night, and we would sleep together in secret. This nightly routine continued, with each of us slipping into each other's rooms under the cover of darkness, adding a thrilling secrecy to our growing bond.]

[She's even continued to tease your cock with her soft, tantalizing movements, her butt pressing and grinding against you as you held her close from behind during your sleep.]

[Her teasing was relentless, leaving you in a near-constant state of torment as your cock endured a hard, aching erection under her ceaseless stimulation. Each time you tried to close your eyes, peace eluded you, haunted by vivid fantasies of taking her forcefully, unable to shake off the intoxicating thought.]

[Finally, you could no longer hold back. You slipped off her pajama pants, rubbing yourself eagerly against her, your cock pressed firmly against her soft skin, your lips meeting hers in a forceful, fevered kiss. Your desire only grew more intense as you continued, both of you heating up together until the first light of morning spilled through the windows.]

[And this experienced continued for a week.]

[On the next unexpected night, your sister surprised you by bringing lubrication, whispering provocatively that she was ready for you to take her anal virginity.]

[You were momentarily speechless, caught off guard, but as her tempting gaze held yours, the tension built up over a week of her incessant teasing reached its peak. You knew you couldn't hold back any longer and resolved to give her a night she would never forget.]

[With anticipation heightening every touch, you began with tender foreplay, applying lubrication to ensure her comfort as you prepared to claim her in this new, intimate way.]

[Her butt was tight, her muscles squeezing around you with an intensity that was almost too much, yet undeniably thrilling, and you pushed through the delicious discomfort, savoring each moment as you both adapted to this deeper rabbit hole.]

[The grip of her ass was overwhelming, embracing your cock with a pressure that made you explode inside her, your release spilling from her as her ass continued to pull more from you. You watched, captivated, as your cum dripped from her ass, her body so insatiable that you found yourself craving her even more.]

[It's good to be you, indeed, as you hug your sister tightly, kiss her goodnight, and sleep with her under the same blanket until the morning sun comes.]

[Her affection for you grew increasingly apparent, and soon it could no longer be hidden. Her eyes held a dangerously obsessive gleam, lingering on me for far too long. Our father, noticing these unsettling changes, grew suspicious and began a covert investigation without our knowledge.]

[When the evidence finally stacked up beyond denial, your adoptive father confronted you with his wrath—he broke your leg and sent you back to the White Room.]

[There, Professor Ayanokouji awaited, greeting you with open arms and a smug, shit-eating grin, as if reveling in your downfall.]

[Since that day, you heard no news of Arisu Sakayanagi. You remained confined to the White Room, destined to stay locked away for the rest of your life.]

[Bad Ending 1 (Arisu Sakayanagi Route): White Room Canary]

[Evaluation: Keep your friends close, but keep your pants closer. Now you understand that self-control is a necessity, signed by your beloved God of Webnovel.]

Fuck you, Webnovel.

[Do you wish to start a new game, Player? Which checkpoint would you like to load?]

Yeah, let's start the new game.

I want to begin from a point where I can maintain a respectful distance from Arisu. Her affection for me doesn't need to be heightened, and if anyone's favor needs to increase, it's her father's.

It would be wise to earn his favor first—before dealing with Arisu's.

Hah…

[Since that case, let the game begin.]

Yes, let the game begin, indeed.
