Erwin felt bad. He really did. Standing in front of this church, seriously thinking about calling in an exorcist for someone who might not even want one? Yeah, he felt pretty bad.

He pressed his lips into a thin line. If he didn't call the exorcist and get Levi's house purified, who would? Certainly not Levi. Levi didn't know the danger he was actually in, or what could happen to him if he kept that spirit with him. He just didn't want what happened to him to happen to Levi. It was traumatic, that was for sure.

Making up his mind, he walked into the church and strode confidently to the priest, who was sitting in a pew. Well, Erwin hoped he was the priest. He was wearing priest clothing.

"Hello?" said the priest. He was bald, completely so, and had wrinkles lining his eyes, forehead, and mouth. He also had a mustache.

"Ah, yes," Erwin said awkwardly, "Do you do exorcisms? I know it sounds silly, but..."

Erwin fidgeted. He knew this was a bad idea. He couldn't even look the priest in the face. He was probably making a face Erwin knew all too well. He couldn't look up.

"Yes," said the priest. His voice was cautious, but Erwin's head shot up. The priest was startled for a second, then laughed.

"Really?" asked Erwin. The excitement in his voice contrasted with the seriousness of his expression.

"Yes, but may I ask why?" asked the priest. "You know, not many people believe in that sort of thing."

"My friend's house is, um, haunted," said Erwin lamely, for lack of a better word, "A kid who died around three months ago is still there. I think he might be dangerous."

Erwin remembered the scene he had walked in on only a few days ago. The lights flickering, the trembling of the room, and the winds that seemed to come from nowhere and everywhere all at once. It was like a slap in the face of Erwin's trauma. A ghost, living in one of his only friend's house. And one that looked that dangerous!

The priest nodded his head. Getting tired of calling him "the priest", Erwin decided to ask his name.

"Pixis." he said, "Dot Pixis. Pleasure to meet you."

He held out his wrinkled hand. Erwin shook it with slight hesitation.

"I'm Erwin Smith." Erwin said with a small smile.

"Levi!" Eren whined. He was laying on the floor, rolling around in boredom. "Come home, won't you?"

Eren tried his best to sound like a heroine in a late 20th century romance, failing miserably. If Levi was there, he would laugh. Hopefully. Probably not. Eren sighed. He was tired of being bored.

He remembered something, the memory hitting him like a big pile of bricks being thrown at his face and instead of standing up and finding whoever threw those bricks and yelling "fuck you" he allowed himself to be absorbed into the floor.

For a few seconds, all Eren could see was the inner workings of th floor. Pieces of wood put together to make something that Levi could stand on, making sure to keep him from falling into the basement. And Eren wanted to keep Levi out of this basement as long as he could. Eren looked around at the pickled body parts laying on shelves in disgust as he seeped through what was now the roof, like a water leak. Or like Slimer from Ghost Busters.

It was really no surprise that Eren would want to keep someone from seeing the floating eyes and livers and various other organs, right? Some of them weren't even pickled, and were just rotting pieces of meat on a table. They were surrounded by knives and scissors. All this time, Eren could hear the soft whirring sounds of machines.

The last time Eren had been here, he had been too worried about Levi to do any real exploring. This time, though, Eren was sure he had at least an hour until Levi came home. Eren started walking aimlessly through the shelves upon shelves nailed sloppily onto the wall, stocked with bottles. Some of the bottles were stacked on top of each other on the floor, and even though Eren knew he couldn't knock them over, he still avoided them.

This basement was nightmare fuel, for sure, but Eren felt like it was familiar. Like the gross body parts actually weren't all that gross to him at all.

He kept walking into he walked straight through a desk. He looked down to see his lower half cut off by the top of the desk and a book. Not "book", really, it was more like a journal. Eren backed out of the desk and leaned down to read the small handwriting. It was dark, and Eren couldn't find a light switch, so it was hard to read.

I've finally found the secret to immortality. I have created a syringe that will...

Here, the ink was smudged. The words bled into each other. Eren could hardly read that, he couldn't read it at all.

Carla, if only I was able to make this before you died. Then, maybe, you could have lived with me forever. Or for as long as you would have liked. We could switch through body after body, different bodies, but the same souls. Wouldn't that be great? But you died before I could make this syringe, darling. Because of some wretched disease, you died. And you could have lived, Carla, dearest, you could have lived if I weren't such a damned fool...

I am ready to test out this syringe. I will need a test subject. I cannot use this on myself. I need to run a few tests on whoever I use. Who shall I use? Someone who is in good shape. Who will not be missed for a few months. I don't really need to go into specifics. I have the perfect test subject here, in my home. I have him here. I can go get him.

Eren was finding it hard to breathe. Of course, breathing was no longer necessary for him, but it was a reflex. What did this mean? Who could...

There was still more. Eren had to keep going. He needed to know.

I have completed the process on Subject A. He is currently connected to life support, which should be able to keep his body alive for around a year. That should be plenty of time fro me to preform my experiments without getting caught. If I go on for too long, however, his body and his soul will die, and I will be discovered. I must act quickly.

Subject A's soul is shining brightly. It takes up the bottle completely. It is a very powerful soul, I think. I am proud. I have run a few tests on him. His body is still functioning normally, as is his brain. That is a relief. There could have been some serious brain damage done once I removed his soul. There could still be some horrific damage, and I am not sure how long his soul can go without a host. Four months at the most, perhaps. He is-

The page stopped there. It couldn't stop there. Eren tried desperately to turn the page, but his fingers slipped through the journal. He had to calm down. Calm down and think.

"What the fuck?" Eren whispered. The sound of machinery reached his ears again and Eren's head swiveled toward the sound. Maybe...

Eren walked hesitantly toward the sound. It was coming from he same room he had heard if last time. Eren was trembling. With fear, yes. With excitement? Maybe.

He reached out to open the door, but his hand went right through the wood.

"Ah, right," Eren muttered, "Ghost."

Eren slipped through the door slowly. He was scared. To be more specific, he was shaking so violently he looked like he was glitching. As he reached the other side, his eyes widened and his breathing became shallow.

Eren screamed.

Levi trudged into his house, tired after a long day's work. He scanned the room for anything Eren might have done. Nothing.

It was strange how this had become routine for him. Searching the room for tipped tables, upside down lamps, pillows thrown carelessly across the floor. It bothered him, for sure, but he was grateful to Eren for remembering to to it every time.

He collapsed on the couch just as he heard a knock at the door. With a frustrated groan, he got up and opened the door.

On the other side was a man he had never seen before. He was old and bald, with a mustache and aged, wise-looking eyes. Levi's gaze fell behind the man onto Erwin, who looked as serious as ever.

"What?" Levi asked unceremoniously. The old man looked startled for a second before laughing.

"I'm here about the ghost." he said. Levi tried his hardest to keep his face looking stoic as he turned to Erwin. Erwin smiled at him apologetically. This was no time for smiling.

"I don't need your... services." Levi said, guessing the worst. Had Erwin seriously called in an exorcist? What the fresh hell was he thinking?

Levi heard rattling behind him and felt his stomach drop. Eren had a bad habit of appearing at the worst times, didn't he?
