Choose me, or die (Yandere/Archer x reader x Yandere/Avenger)

You stared in triumph at your servant, after finally summoning the Archer class that you were hoping for. Although he wasn't as enthusiastic as you were at being summoned to this world, he still accepted you as his master and relaxed at the couch nearby. The summoning had taken a lot out of you, judging by the way you had wobbled at first, and your servant had to help you up after you fell on him. The mere contact of him made you blush, and you quickly regained your balance.

You glanced at the mark on your hand, watching the red glow for a moment. You decided to rest until you had enough energy to hold yourself up. Despite wanting to be a damsel in distress to your handsome servant, you noticed he wasn't the type to constantly hold your hand. He would get annoyed with you as soon as possible, if you purposely became a nuisance. You thought better to keep a good relationship with him. After all, the holy grail war wasn't to be taken lightly. You needed to work together properly to survive.

When you relied Archer of your plan to rest before patrolling the city at a later time, he merely hummed and closed his eyes in thought. You tilt your head when he had no comment. "What is it?"

"I recommend you do so after what happened earlier." He mentioned, looking towards the moon shining brightly through your bedroom window.

You blushed once again at the memory. "I-I didn't mean to fall on you. I felt light-headed and-"

Archer held up his hand, immediately stopping you. "I can tell you are a weak magi, so don't bother explaining. For now, just rest and we'll talk later."

The way he shut you up made you pout, but you decided not to argue any further. Instead, you went to your large bed further into the room and laid back on the sheets. You yawned, cuddling into the blankets when you spotted Archer move in the corner of your eye. The man had stood up from the couch, and watched you from where he stood. You were beyond tired and your eyes felt heavy, that you couldn't catch him walk towards your bed.

Steady breathing was heard as you fell into a peaceful sleep. The summoning did a number on you, since you were oblivious to Archer staring down at you with his usual scowl.

There was something strange about you. You were a weak magi, yet you held such a malicious yet powerful magic inside you. Archer glared at your form, until he spotted something on your arm that confirmed his suspicions. He was tempted to pull out his weapon and kill you in your sleep, by the way the malicious aura surrounded you. Such aura can corrupt one's mind and make them do horrible things.

He stopped himself from summoning his weapon and held his head. He knew the aura was purposely messing with him. He also knew, he wasn't the only one summoned. Which was why you were so drained from the summoning. He glanced at you when you whimpered in your sleep, and scowled once again.

"Who are you?" He muttered.

"....a girl...." You heard in the depths of your dreams. Even though you were in a war where blood would be shed, you didn't think you'd dream about it. You were surrounded by red, red and more red. The crimson color surrounded you, as you tried looking around for anything or anyone. The sinister atmosphere didn't help you in the least. You felt a shiver go through you, despite being in your dream. It was like the color was telling you that a presence here wanted nothing more than to kill. 'What's going on?' You thought, hugging your form as you floated around the constant red.

"...A surprise..." You heard the words echo around you. You wondered whose voice it was, since it certainly wasn't Archer's. You had expected to dream about Archer's memories, but the atmosphere held a more sinister and malicious aura. Nothing here felt anything like Archer, since he wasn't like that, from what you can tell now.

"Can you... me, girl?" Said the voice. The voice was much louder than before, that you covered your ears to block the sounds. Apparently it didn't work, since the voice still rang in your ears, causing you to wince in pain.

When the voice continued to echo, you shook your head. "What?" You responded, not clearly hearing the voice echoing around you. "What are you saying? Who are you?"

All of a sudden, you felt hands caress your sides. You gasped and went to stop those hands, when you felt only yourself. You blinked in surprise. You could have sworn you felt hands on you. Another hand touched your shoulder, causing you to gasp and look for the hand. Nothing and no one was present. "Who's there?!"

No response, but another hand had touched your cheek. Another caressed your sides again, while another went to touch your bare thighs. You squealed and tried covering yourself, when you realized you were naked. More hands continued to touch and feel around your form, as you did your best to cover yourself. You couldn't see where the hands were coming from, you were blinded by the crimson color around you. Deep chuckles rang through your head, making you cry out in pain at the ringing in your ears. You held your ears to block them out, giving the roaming hands access to your exposed chest.

"Stop it!" You yelled out to the chuckle, that continued to resound in your head. The random hands continued to feel and caress your bare body, occasionally sending waves of fear and pleasure through you. You felt violated by the way they touched you, and tried to expose more of you, as you thrashed around to get away from them. "What do you want?!" You screamed.

The hands stopped, and no longer touched you. You panted, daring yourself to remove your hands from your ears. As you removed them, your eyes widened. You shivered at the amused voice that whispered in your ear. "Let's do this again soon, girl."
