Yandere!Kuroko Tetsuya x Reader

"Let me higher, get me higher. Moeru mi no atsusa wa. Nanto naku no kyou demo burnin' up, we love shinjite. Rock me baby, show me baby, misete kure motto. Ore to kimi to de tsukuri agerunda. Densetsu wo other self!" You sing happily.

"Oi, please don't sing that song, _." Your older brother, Daiki, complains. Your lips formed a pout that made Daiki roll his eyes. "That's not going to work. Why are even singing?"

"I get to go to basketball practice with u!" Your real intentions were hidden by that conceivable smile plastered on your face, making Daiki raise his eyebrow in suspicion. Even though Daiki wasn't the smartest, he is your older brother. He could see right through you.

"You want to see Tetsu." His blue eyes narrowed, as well as his brows. The thin line, known as his mouth, made a slow move, transforming it into a frown.

You knew your attempts to become a tsundere were futile, so you simply smiled your traditional smile.

"Heh, you saw right through me. Yep. I want to see Kuroko-san!" Daiki widened his eyes slightly and his ocean blue eyes strayed from your (e/c) ones. You tilt your head innocently. "What's wrong, Dai-nii?"

"N-Nothing. I'm going to skip practice today, so... Yeah. You can go see Tetsu, though." You saw a hint of fear in his eyes, but you decided to ignore it. Why would somebody be afraid of Kuroko-san? You thought he was the cutest and the most innocent person ever.

Looks can be deceiving, right?

"I-I like you, Kuroko-san! Please go out with me!" You confessed to Tetsuya. His baby blue eyes widened, but he smiled nonetheless. Your eyes were shut closed, getting ready for the rejection/confirmation awaiting you.

"Okay, _-san. I like you, too." Tetsuya was an excellent actor. He used his invisibility to hide his true intentions, something you weren't aware of... Yet.

He smiled softly and leaned into your face. This was your first kiss, so you weren't really experienced with this stuff. Tetsuya realized that and took it slow, which you gladly accepted.

Tetsuya and you have been dating for a few weeks now and something about him irked you. You couldn't tell what it was. Tetsuya would randomly appear whenever you'd talk to any of the Kiseki no Sedai, even Daiki.

"Seijuro-san! Can you teach me how to play shogi?" You asked. Seijuro smirked softly and nodded.

"Sure, _." Seijuro agreed to teach you, making you smile happily.

"Im sorry, Akashi-kun, but _ and I have some important things to attend." Tetsuya gripped your hand with intense power, making you flinch slightly.

"Is that so? Maybe next time, _."

"Okay! Thanks again, Seijuro!" You waved at the captain with your free hand and Tetsuya's grasp on your hand became as tight as a snake's coil on its' food.

"T-Tetsuya... That hurts, you know?" You say through tears. He stopped walking and his eyes pierced into yours. You widened your eyes.

His serene blue eyes became icy and cold. You could see pure hatred in your boyfriend's eyes.

"Tetsuya?"

He switched hands. Your free hand was now the one being gripped. Tetsuya's fingers around your wrist became like a handcuff. You couldn't escape this prison.

"You are mine and only mine. You cannot talk to anyone or anything, but me." His eyes stabbed you right in the heart. This wasn't the man you fell in love with.

Before you knew it, your sight turned black. You couldn't see anything anymore.

"Are you awake, _?" The sweet, yet sickening, voice of your boyfriend woke you up. You flickered your eyes opened and looked at the twisted smile that greeted you from your nap. "Good. I have vanilla shake for you."

He poked the straw into your mouth, but your lips quivered. Where were you? You tried moving, but your already bruised hands were handcuffed to a chair.

"Why are you trying to leave, _? Didn't you love me?" Tetsuya's smile made shivers run down your spine.

"W-Where am I, Tetsuya?" You stutter out.

"Don't worry. You're safe from the atrocities outside. This will be our new house, _." You suddenly felt ice cold lips press against yours'. Your lips never failed to quiver, but Tetsuya took advantage of this and deepened the kiss. You felt a tear roll down from your cheek.

You've tried escaping countless of times, but having an invisible boyfriend is hard to avoid.

"_? Where do you think you're going?" That infamous smile of his made you terrified of the Phantom Sixth Man.

"What happened to your real self?" Those were the first words you said since you became stuck in the prison if hell. Tetsuya raises an eyebrow and smiles.

"What are you talking about? This is my real self. The Phantom Sixth Man? That... That was my other self." You widened your eyes.

"Oi, please don't sing that song, _" Your older brother's voice echoes in your head.

Then it hit you. Did Daiki began skipping basketball practice because of Tetsuya? Was that the reason why Daiki told you not to sing that song?

Little did you know that Daiki's detachment from the team was the reason of his shadow, his trusted best friend.

"Dai-chan! You need to attend practice! Tetsu-kun misses you!" Satsuki yells out from the roof. Daiki flinched a bit and he sat up, dark blue eyes piercing Satsuki's rose-like ones.

"You don't understand, Satsuki, and I think it's best if you don't." Daiki couldn't tell her the details. If anything leaks out about Tetsuya's real self, your head would no longer be attached to your body.

"I haven't seen _-chan in a while, what happened?" Daiki shut his eyes closed and bit his bottom lip to stop himself from crying. He knew that you were trapped in his ex-best friend's house, but he couldn't do anything about it. That's what he hated the most.

Having no ability to save you whatsoever.

"She transferred to a different school." That was the only lie Daiki could think of.

"EHHHH? Really?" Satsuki screamed. You and her were best friends and she supported your feelings for Tetsuya even though she liked him, too.

"You're mine forever, right, _." Tetsuya asks softly, caressing your cheek with his frigid hands. You flinched and nodded softly.

"Y-Yes..." You lied. You couldn't believe yourself. You fell in love and dated a person like him. He held you like an item and a toy.

"Good girl. Hey, did you hear? I'm graduating soon. You're transferring to Seirin High with me. Isn't that great? We can stay together forever." Tetsuya kisses you for the ten millionth time. He gives you around 20 kisses every day, maybe even more.

You transferred to Seirin with a fake name and a fake identity. You were _ Kuroko, Tetsuya's fiancé. Tetsuya forced you to smile and you attempted, it was fake but it was better than nothing.

You supported the Seirin basketball team and became good friends with their coach, but... That was just your life outside.

You were living in hell and in just a matter of a few months, a man named Kagami Taiga sat in the empty chair next to you. He was Tetsuya's new light and new torture dummy.

"I'm tired of being in the shadows. I can do it."

If you want more, please review! I will do all of the Generation of Miracles and Kagami as a yandere.

Next will be a yandere Kise Ryota!
