Yandere OC 's x Reader (One-shots)

Yandere! Ally x Reader

Your ally is Akihito, a boy with orange hair and red eyes. You two battle villains together for almost three years. You are Guardians of Luminance. You two are allies.

But there is something strange about Akihito. Whenever a villain is in love with you and is trying to take you away, he will get on a rampage. His head will twitch and he will laugh whenever he killed his rivals. Also, whenever you two are in your normal selves, he will always stick with you. He is happy whenever he is following you around.

One time, he killed a villain who is one of his rivals. He laughed and laughed like it will never end. You hid behind the golden gate and shivers went down your spine.

"Something is really wrong with Aki," you thought to yourself. "This is not a personality a hero should have. Why is he so insanely happy whenever he kills a villain who likes me?"

You turned around again. Your fear went up when you saw Akihito stabbing the villain with a small sword! Blood scattered everywhere! Also, his head is now twitching like crazy and he is laughing!

"AHAHAHAHA HAHAHAHAHAHA!!!! HAHAHAAAA HAHAHAHAHAHAHA!!!! YOU LIKE THAT!!??"

After that, he turned the corpse into sand with his powers and magically cleaned himself up. Later, he turned around and saw you.

"(Y/n)-chan!" he happily said and hugged you. "We did it! We saved the day!"

"Y-yeah...," you just said.

Four days later...

You and Akihito met at the school park that time. You wanted to talk about Akihito's weird behavior towards villains.

"Aki-kun, listen," you said. "I wanted to talk about something..."

"About what, (y/n)-chan?" he asked.

But you changed your mind later. You don't want Akihito go get angry with you.

"Oh, it's nothing," you said. "I don't want to talk about it."

"I'm your friend, remember? We're allies. You can tell me something."

"I guess there's one thing I want to talk about."

"Sure. I'm listening."

You just shared your personal problem to him (state your problem in the comments).

"Well, it's okay," Akihito just said to you and tapped your shoulder. "All problems have solutions. I can help you solve them if you want."

"Thanks," you said and smiled. "You're kind."

But then, you somehow saw Akihito staring at you with soulless eyes.

I love you, (y/n)-chan. I won't let anyone else get in between us. I will eliminate them... even through murder!

Later, you two battled another villain in the evening. The black haired villain grabbed you and kissed you.

Akihito saw this and his face is like a mad dog when he attacked the villain. He instantly slain him with his golden and magic sword.

"NO ONE IS LOVING (Y/N)-CHAN BUT ME!!!" he shouted. Then, he turned his sword into a staff and tries to beat his enemy up with it.

"HEY! THIS ISN'T SUPPOSED TO BE LIKE THIS!!" the villain shouted, but Akihito put his magic energy into his staff and starts beating the enemy up.

You became mentally scarred when you watched your ally being like this. He is not the Akihito you've known before. He is a totally psychotic person.

"DIE! DIE! DIE! DIIIIEEEEEE!!!!!"

The bloody Akihito then happily hugged you.

"I love you, (y/n)-chan..." he whispered in your ear.

You got traumatized... especially when he touched your face with bloody hands.
