You are Yandere Monster's master and creator—conjuring him to life the moment your pen—yes, your pen—leaked onto paper. The ink created a blob with a single, long, winding arm. He looked like a poorly drawn B.O.B from Heros and Villains coming to life, popping out from the page, and awkwardly flapped about on your white apartment floor. He had left ink blotches here and there, staining parts of your carpet. And when he tried to push himself up on his one arm, he landed face or body first, right back onto the ground—causing tiny splatters to fly onto your clothes. It seemed as if the monster's arm couldn't support his asymmetrical top-heavy shape, and he let out a small whine. Slinking himself back into a corner, his form now vibrating as he bundled himself back up. He was ugly and inhuman—an atrocity and a mistake. So, you scream, of course. You yell at him to get out, throwing your couch pillows at his scared form. However, the monster surprisingly responds with quick swiftness and dodged each and every one of them.
Yandere Monster loves to fight back. You were forced to run around your couch as he began to chase you, using his one good arm to propel himself. On your fifth lap, you managed to grab your pen off the table. Letting out a battle cry, you hurled it at him with all of your might. The pen soared into the air, shooting upward towards the ceiling before finally arcing back down to him. In your mind, you imagined it piercing whatever passed for a heart in his body, followed by the gruesome task of disposing of it. Oh, you’d have to scrub your hands raw. But instead, he caught the pen effortlessly— and crushed it within his palm. Black ink oozed out, slithering as if it had a mind of its own, creeping up his arm to his shoulder before disappearing into two narrow slits. He snorted the essence.
Yandere Monster grows in size. He screeches out of agony. The walls trembling in response. You watched him double—no triple in height! With the extra ink, he gained more limbs that tore through his oblong body. Four arms, two legs, and a face that was void of anything besides two blinking eyes. His nose and mouth hidden, only appearing when he takes a haggard breath and his long slimy tongue wets his lips. You thought it was over until he dove for your stationary gel pens. Chewing on a glittery bubblegum pink ink that permanently gave him cute kawaii blush on his cheeks. He then moved on to the grays and blues, the mix of them adding color to his iris.
“…are you customizing yourself...?” you ask out of astonishment, only getting a snarl from him in response.
The monsters head then swiveled around to stare at one of your windows, sizing it up. Surely, he could jump out of there. He slowly backed up and got into position. "Mrrrg?!" he tensed up when he felt your arms wrapped around his torso, already dragging him away. It was like you could read his mind and it was frustrating to no end.
Yandere Monster becomes your roommate. He didn't know why he had explained his evil plan to you with the very limited vocalizations he had. But with short grunts and simple hand movements, you caught onto it right away. You could see it now: the city crumbling and burned to ash, people screaming as he grabs them all with his huge hand before tossing them into his mouth as if they were a light snack, and the worst of all, he'll find every pen in the world and rid of its ink. Yandere Monster wanted to get bigger, stronger, and more lethal. All qualities he deemed he needed to take over the entire world. When he finished playing charades with you, he couldn't help but to notice the horror etched on your face. All of the life drained from your eyes, and you took a step away from him. He tilts his head, now watching the way you paced back and forth. You were distraught and went on a tyrant about your loved ones. It sounded like garbled noises to him. The English language was something he still had to get used to, and he scratched his cheek. Even a brow was quizzically raised.
He was starting to get the sense that you cared a lot about a lot of things. The earth, what would happen to the animals after he got rid of every single human, and your friends and family. The monster could only bite his inner cheek now, slumping against your wall despite your protest, and pondered for a moment. Maybe you were right. He looked down at himself. He wasn't made to be a killer. He wasn't even made with any purpose at all! He didn't have to go that route and can actually contribute to society in a meaningful way.
You were… right.
He nodded along to your words after you had calmed down, and to his elation, you had offered an olive branch to him.
Yandere Monster watched you slime proof the house. He wasn’t sure if he should be offended by how grossed out you were from his goo. You would scrub at your sheets and floors for hours before he could permanently stain your residence and belongings. You had even bought plastic covers, but that too, needed constant maintenance. In the end, you needed to nip the bud of the issue. You wrapped his body up in plastic saranwrap, making him twirl around like a pretty little ballerina. He was also given a life-sized ball so he could freely roam the house without leaving a trail.
It definitely didn’t annoy you whenever he kept bumping into your desk for attention. Thud. Thud. Thud. It also didn’t irritate you at all when he would launch himself at you for a laugh—bouncing right off you and barreling into your more delicate items.
Yandere Monster was the naughtiest roommate/friend you have ever had. He, however, did revert back to his coward self when you raised your voice at him. Your scolding tone brought back memories of his non-existent mother, and you just knew how to instill fear into him. “Hss!” the Monster would scream, shielding his eyes from the picture you held in front of him. How dare you! How dare you make him stare at children having fun and laughing! His skin crawled at the sight of their smiles. Yandere monster had to run away, slinking into the bathtub, and curled up in a little ball. Despite this, he continued to wreak havoc on you and the poor morsels that had unfortunately crossed paths with him.
Pranks were sort of his specialty. You had an egg sandwich in your fridge, and he scooped out the filling just to switch it out with potato salad instead. You brought strawberry jam last night and had it on the side cabinet. He picked it up, silently and carefully, and hid it behind a huge jar of mayo. It took you a good minute to find the jam, and he hehe'd the whole entire time.
Yandere Monster hated human customs. He hated learning in general and did the complete opposite of everything you did. If you opened a door for a man, he would intercept and slam it back in their face.
“These people don’t deserve your kindness!” he often hissed at you, “They don’t even deserve a second look and should be holding their breath around you!”
And yet all you heard was, “Eergh! Mrrph. Gaaah! Grrr! Hissss!”
He also never said “good morning” or “good night” to anyone, and he never said “hi” when picking up the phone for you either. He would be silent. Dead silent—making them repeat themselves over and over again before eventually hanging up. He would purposefully jam his finger into the “close door” button in the elevator, smiling condescendingly at the disgruntled and now very sweaty person. The sounds of their fists slamming into the metal echoes as you two went down to the garage.
Since he’s not allowed to kill people, he’s going to greatly, greatly inconvenience everyone!
Yandere Monster was introduced to your family for game night. He was squished between your father and a little boy you called “nephew” and “Henry” on the couch. Even if he barely spoke to the older man next to him, the presence of him was enough to make his skin prick up. He was cold, only charming when he needed to be, and yandere monster was afraid to even breathe near him. Monopoly was the game you chose, and smartly as well. You were the richest amongst all of the players. And the monster was completely stumped! As the game went on, he was drained of all of his money and assets, and the hotels he earned early on was easily swiped from his hands by the aggravating kid next to him. And now he was in jail?! Oh man, this sucks! He huffed, cheeks puffing out as he crossed his arms and defeatedly looked away from the board.
"Here, have some of my cash." You offered, sliding a couple of colorful bills across the table. He oddly felt...warm inside. Tingly. A deep rouge appeared on his face, his eyes darting away from yours when he grabbed for the paper. It crumpled. He gripped it tightly and kept it close to his chest.
When the little boy tried to steal from him once more, he hissed.
Yandere Monster upgraded to your fuck buddy. You regarded him as nothing more and nothing less. Only letting him get a taste of you whenever you felt like it. You two could be making out everywhere with your lipstick being sucked off your face to being nothing and distant strangers all at once. You would be on top of him during your lonely nights, grinding onto him with reckless abandon, and say that you "really needed this." And after your short, euphoric high, you never seemed to be reaching out for him again.
Yandere Monster wished you were more punctual. He hated how his presence became easily forgettable to you the moment he wasn't a threat no more. He needed five meals a day, y/n, and that wasn't up for negotiation. Meat upon meat with very minimal veggies on the side was his go-to. Although, he wouldn't mind getting a treat and eat ice-cream before dinner. He growled again, crawling towards your feet. He learned that if he made himself as small as possible, you were more open to listening to his demands. One time, you had let him in your bed after you found him curled up like a dog on the ground besides you. He insistently nudges your leg with his head, whimpering the word "food" he learned from you.
His face now travels toward your inner thigh, disappearing underneath your nightgown. His breath was warm and steady, brushing up against your panties. "I'm hungry..." he mumbles, a hand placed on your knee to keep yourself spread from him.
Yandere Monster preferred the warmth and subsistence your body offered—craving it quite more often than he should. He can’t help but to whine and pant, voicing his frustration while holding your legs to his chest. Being with you was great and he'll take whatever you'll give him. However, he had dreamt of the days when you would finally bestow him the honor of being inside your cunt. Your thighs are painted with a sticky dark purple slime; his pulsing and throbbing manhood are nestled in between them. His nails dug into the skin around your ankles, now pulling your legs apart into a wide v. You look absolutely adorable beneath him. Your gown pushed up to your chest, showing just a sliver of under boob. And then... there was your torso. Marred with stinging red claw marks and love bites. He's a little rough, the quivering bottom lip of his turning into a full taunting shit-eating grin. Staring at you as if he was still starved.

I looooooooove foreshadowing like. Something is about to happen. Its presence echoes even throughout the past, trying desperately to get someone to recognize it for what it is. Something is about to happen. It's like a prophecy told without a voice. An echo from nothing. It's like seeing a target on your beloved characters that they themselves can't see. Something is about to happen. Sometimes even you can't see it until it's too late. Until something happens.
