Half and Half (Oblivious!Eren x Reader x Slight!Yandere Levi)

Separation and Loss

As you followed your newly assigned squad (Thanks to Hanji), you quickly remembered the formation of the plan. And once you were in the middle of the field, flares began sparking up the sky with a faint color of green. Eren hooked his chin onto one of your shoulder blades to see the sky colored with a single streak of green.

"Wow..." Eren watched in awry.

"It's a good sign. You remember that, right?" You asked.

"Yeah. Red means bad. Black means aberrant."

"Good job." You praised him.

Eren no longer had amnesia. He can remember everything since the day you took him in. He replayed those memories in his mind over and over, cherishing the moments with you. you were glad that Eren had fallen into your hands in the first place. You had to give fate some credit.

"The wind feels nice today." You commented.

Eren couldn't keep his eyes off the clouded bright sky. He was almost distracted by it until you interrupted him.

"It's almost time for you to shift. We're going to encounter a group of titans just up ahead. The formation will be split up. You and I are going to charge through. That's the rendezvous point. We'll meet up with Reiner there.

"Alright." Eren understood your words.

"Get ready...."

As soon as you came close to your destination, you witnessed Reiner from afar, shifting into his monstrous form. That was the signal to have Eren transform as well. Without any orders, Eren jumps off the horse. You began to steer away to join up with the other groups on the sideline. A strike of lightning hits Eren as he shape shifts into a titan. You didn't look back, instead, you continued on forward. Basically, Reiner and Eren were baits to lure the other titan shifters to come. But who knows how this'll turn out?

When you met Hanji face to face, she commands the other squads to aid the titan allies. You helped exterminate the titans during the brief fight. Soon, more and more kept coming and there was still no sign of a unique titan that looked out of place. Having difficulty fighting with the giants in an open green field, more of your squad members were dying. You were losing men, and you dared not to keep track of whom you will not be seeing tomorrow. You tried your best to help those who were in danger but nonetheless, people were getting eaten from left and right.

"Dammit! If we keep this up, we'll..." Suddenly you noticed a giant skinless hand grabbing a horde of titans in its palm and sent them flying away from the battlefield. You followed the hand to the arms to the face. You've seen it before.

"It's the colossal titan! We must capture it!!" You hear Erwin shout.

As you looked over to Reiner, you can see that he was frozen in shock to see the colossal titan. And honestly, you knew that this wasn't going to end well.

"Reiner!?" You called out.

Eren was still busy clearing his own personal area while Reiner stood there, motionless, allowing the titans to gobble his solid shield. Strange.

"Hanji! Reiner's not moving!!" You informed her.

"We can't do anything about it! Erwin's squad is taking care of the colossal titan! Just keep going!" She tells you.

Somehow, you couldn't listen to her words. You had to do something to Reiner. But suddenly, you noticed a small figure standing on the nape of Eren's neck. You squinted your eyes to see that it was someone unfamiliar, wearing the same uniform, the same gear. You were confused at first. Why would someone try to take out their own ally?
