"Are you sure about this, trainee Arlert?"

"Yes, sir. He is most likely a vampire. I've noticed that he acts very sleepy during the day while at night he is auite energetic. I've also seen him slipping out at night several times only to find another victim the next morning. As much as I wish it wasn't true I can't overlook the facts. He's the one we're looking for."

Shadis got up from his chair and turned his back to Armin to look out of the window. "So, how do we catch him?" he asked after a while.

Armin smiled. "I think I have a plan.

...

Sunlight woke Eren from his peaceful slumber. Of course. He had to be the one to get the bed that sees the sun first in the motning. He yawned as he rubed his eyes, slowly siting up. That's when he noticed that the other beds were already empty. The others had already woken up and were eating breakfast.

With a quiet groan he got out of bed, dressed up and took off to the dining room. He skiped two stepps at time as he decended to the ground floor, hoping he hadn't missed the meal. He sighed in releaf as he noticed his friends had just started eating.

"Eren, you're finaly awake!"

Eren sat next to Armin and looked at his breakfast; bread and butter.

"So, how come you're all up this early?" he asked, not noticing that all eyes were on him.

"We found a way to catch the killer. But first, let's eat." Armin answered with a small sound of sadness in his voice.

...

Eren arrived at the Wallist church. This is the place where they would catch the killer, being a place where religious gathered. A church was also the place where the monster would last strike.

He entered the building and the first thing he noticed was that the windows were placed just right for sunlight to illuminate the room in the late afternoon, the time they would act. Just like in the story.

Eren looked around for any unfortunate soul that hadn't been warned of monster-hunting taking place this day. Since there wasn't any he smiled and rubbed his hands together. He had time until lunch and he had quite some work to do.

...

Jean looked oround the church, proud of his work. He had finaly finished the preperations for the day's mission. And just in time; it was almost five pm, which meant the others would arive soon.

'This is it,' he thought. 'Today we finish this. Today that bastard faces justice.'

The gates opened and his comrades entered the church, grim looks on their faces. One of them was the killer. One of them was a monster. They slowly moved to the altar upon which lay a few lit candles in the middle of the church. This ends here and now.

"So, here we all are," stated Armin, gettin the attention of his comrades. "Are we all ready?"

The young soldiers noded, remembering the plans they had discussed before breakfast that day. No turning back now. Time to go to work.

Reiner grabbed Eren's wrists and twisted the smaller kid's arms behind his back. Eren, a bit surprised by the action, quickly reacted, throwing Reiner over his shoulder into a wall ten meters away. The other trainees saw this and quicklyy pinned Eren to the ground.

"So, it was you all along."

Eren threw a grim smile to his childhood friend. "Yes it was. Well done, Armin. I didn't expect anything less from you." He shifted under the weight of his comrades, but was unable to do anything.

Armin moved closer, tears gathering in his eyes. "Eren, why?"

"Why? So that we can one day liberate humanity from theese walls. I need blood, it makes me stronger. Don't you see? With this power we can win this war."

Armin shook his head in disagreement. "No, Eren. Killing people isn't the way to liberate them." He took a step back. "I'm sorry. This is where it ends." He turned to Mikasa. "Do it."

Eren tried to get out of his comrades' hold as Mikasa walked over to him with a pole in her hand. Though she held an emotionless face everyone knew that inide she was screaming in pain. She of all people had to kill Eren. Her only family.

Eren looked at her with pleading eyes. "Mikasa, don't do this! Do you not remember all the time we spent together. I'm your family, maybe even more."

Mikasa stopped, causing Eren to smile. "Come on, with this we can leave the walls and be together forever."

Mikasa dropped the pole. What was she doing. Wasn't this what she had always wanted? Being with Eren?

Eren felt the pressure on him lighten as his comrades lost concentration, trying to process his words. He used the confusion and freed himself of the soldiers' grip, leaping to the corner of the church and grabbing a rope the others hadn't noticed earlier.

"Lights out," he silently said as he pulled the rope, coering the windows with curtains he had placed that morning, knowing full well he now had no other way out but to kill his comrades. Darkness fell on the church and the only lihht was comming from the half-burnt candles in the middle.

...

"He will most undoubtedly find a way to block sunlight out of the church."

"So what do we do?"

"First of all, we need to take care that his movement is limited. Also we'll want to keep track of his location in the dark."

Ringing was heard around them as Eren, moving around the darkness gently tripped over one of the set ropes upon which several bells were hung. They would know which way he'd be comming from. However, he was too fast. It wasn't long before several trainees were pulled into the darkness, their screams informing the remaining of their terrible fate.

"However, I believe that he would still be too fast for us, so that won't be enough."

"How about we use something he might be vulnerable to."

Eren laughed. "Garlic? Realy Armin? I'm offended."

More trainees were pulled into the darkness, leaving only Armin an Mikasa.

Mikasa was mentaly scolding herself for hesitating. Eren had used her feelings for him against her and for that everyone died. Well, she can't say she hadn't been warned.

"My offer still stands. We can go out there, visit the ocean and live for an eternity."

Armin yelled: "Never! This is not the way to do it!"

Mikasa was still in her thoughts, so she didn't notice that Armin was no longer in the light of the candles.

"How about you, Mikasa? Do you want to spend an eternity with me?"

Mikasa lifted her gaze to see the silhouette of Eren in the darkness, a sword in his hand. No, this wasn't Eren. In that moment Mikasa knew what she had to do. She grabbed the pole lying on the groundt with her right hand and unsheathed one of her swords.

"I guess that's a no then."

"Should all else fail we need to have a way to uncover the windows to let the light in. Jean, I hope you know what to do."

Mikasa dodged Eren's attack and ran towards the door. She cut the rope holding the curtains and light returned to the church. Jean had placed it there, taking care that it was the only thing holding them.

Mikasa turned around to face Eren, who had fallen to the floor as light suddenly hit him. Ignoring the bodies of her comrades laid tidily against the walls of the church she charged at him

Noticing her approaching he stood up but he was too late. He could only lift his sword as Mikasa stabbed him through the heart with the pole.

She had done it, but it came at a price. Her chest was pierced by Eren's blade. As they both bled there, Mikasa spoke with her last breath: "I promised I'd protect you. But I failed to protect you from your greatest enemy: yourself."
