Summary: Levi is forced to jump into the ocean after his ship mates find something out about him...Eren is just swimming around, watching a ship, when he sees a beautiful man jump into the ocean and he can't stop himself from going to save him.
(Part 1 of 12 of my Attack on Titan mermaid au series. I will be adding a second chapter to this tomorrow most likely.)

AN: This will be a series of a bunch of different stories that have nothing to do with each other. The only thing they have in common is that they have to do with one or more characters being mermaids.

Disclaimer: I do not own Attack on Titan. If I did everything would be different.

Levi-

"Let's slit his throat and burn him!" One person shouts. I don't see who it was that spoke that but I am guessing it was Oluo.

"No let's-" Whoever was going to say what to do with me instead was cut off by a commanding voice. It was the Commander.

"Throw this..this thing overboard!" Erwins voice holds disgust in it and I almost roll my eyes.

They were all acting like I was a freak, some type of monster that needed to be killed. Erwin especially was acting that way. I guess I sort of was in their eyes though. I mean you can't have a homosexual Captain of a pirate ship! Though personally I think most of them don't mind that I am homoesexual but they wouldn't dare go against Erwin Smith, the Commander of their ship.

"Yes, Commander!" All of them say as they salute him. I notice that Petra, Hange, and Mike don't join in with the others and all are glaring at Erwin. Well Hange and Mike are glaring. Petra looked like she was about to cry.

I stare at my "friends" with my back straight and a sneer on my face. I would not let them see that what they were saying and about to do hurt me and sort of scared me a little. Erwin knew from long talks between the two of us that I could not swim and that my worst fear was drowning. The sick bastard probably took pleasure in telling us all how I would be dealt with because it was the one way I did not want to die at all.

"You there, you toss him overboard," Erwin says pointing towards somebody behind me.

"Yes, sir!" I stand still as I wait for the person who had spoken to grab me and do exactly as Erwin had said. Everyone is still and silent now, except for Petra who is making small whimpering noises as she cries and Hange as she tries to shush Petra. I tense when I feel hands grab my arms and pull them tight behind me.

"Okay, get a move on it. You know where to go."

I do as the person said and walk towards the side of the ship where the plank is. The people who are in my way move quickly, not wanting me to touch them. I keep walking until I reach the end of the plank. I take a deep breath and stand still for a few seconds.

"Come on!"

I open my eyes and roll them. Jeez, can't this person give me a break? I was just about to die. Couldn't they let me have a few seconds of peace before that happened? Shaking my head, I take my first step onto the plank and the person lets go of my arms. I walk slowly until I am at the end of the plank. Taking one last deep breath, I look over my shoulder. Everyone is still there, watching me. Erwin has a strange look on his face now but I don't really care to bother why. Turning back towards the ocean I take what will certainly be my last breath before jumping off of the plank and into the oceans depths.

It feels like forever before I hit the water, but was probably only seconds. I keep my mouth firmly shut even though I wanted to gasp at the coldness of the water. My eyes fly open though before I could stop them and I can't stop myself from looking up, watching as the bottom of the ship gets further and further away as I start sinking down, down, down..

My lungs are starting to ache a little from holding my breath so long but I refuse to open my mouth. I rather die this way than to die from water rushing into my lungs and such. I am about to close my eyes because I felt really tired but suddenly I see something move in front of me and my eyes fly wide open. What was that? Before I can wonder too long what ever that was is in front of me. It looked like the body of a giant fish! My mouth flies open and I try to scream. Nothing comes out though but something does go in. Right away my mouth and soon lungs are filled with water and I start to panic. No! This was not how I wanted to die! I was supposed to die with my mouth closed, not with it wide open and some giant fish that was probably going to eat my body.

I start to sink faster than I had been before with the way I have started to jerk around and what had scared me before is long forgotten. I close my eyes as I start to feel myself lose conscious. I was going to die from drowning. My worst fear had come true…and just like that my mind goes blank.

Eren-

I stare at the ship with wonderment as I swim around it. I have seen a ton of them before but I have never dared to go this close before. If Mikasa found out about this I am sure she would have my tail but oh well. I could not find it in me to care. I have always wanted to see one up close and now that I finally am able to I am really excited.

Laughing, I move closer to the surface, until I am almost able to stick my head above it. Oh, what would happen if I were to just take one small peak about surface? Nothing terribly bad I am sure. Biting my lip, I stick my head out from the water and I gasp. Oh, it was beautiful! Down from below the ship looked really pretty but up here it was even more amazing! It was a dark brown color with a weird golden tint in it in some places.

I stare at the ship for a few minutes, just taking in the sheer prettiness of it before I decide it is time to go back under. I had spent too much time above water as it was. Giving a small, sad sigh I am about to just that when I see movement at the edge of the ship by a piece of it that sticks out further over the water than the rest of it does. What was going on?

I gasp when suddenly there is a human male there. He was the most beautiful being I had ever seen! From how far away I was I could tell he was well built. His arms looked strong enough to hold me up. I blush at the thoughts that pop into my mind from that one thought. No bad, Eren! Giggling, I push those thoughts away and I make myself start to wonder more about what the man is doing.

Like what was he doing at the edge of the thing though? As if having heard my thoughts the man jumps, showing me why he was there. I give a small gasp and almost laugh when he lands in the water. Not many humans liked to jump off ships and take a swim. From stories I had heard only ones who wanted to die did that.

My heart suddenly starts beating faster after thinking that. This human wanted to die? No, no I could not let that happen! Just from those few seconds of looking at him I already knew he was the one for me most likely, my soul mate. I had never believed it until now and I can't help but feeling a little stupid about that. Maybe my mate killing himself was punishment for me not believing soul mates were possible. Frowning, I quickly hurry back under the surface under the water and towards where I had seen the man go under.

It is easy to find him. He is just sinking downwards from the surface of the water, his head tilted back so he could stare up as he did I am guessing. I frown. Why was he not trying to swim up? To survive because did humans not need to be above water to be able to breath? I hurry closer. It was no more obvious that my mate was wanting to kill himself and I did not like that one bit.

I swim up close to him and am about to say something when suddenly the man's mouth opens and bubbles come out. He looked scared of me and I frown. He had no reason to be scared of me! Before I could wonder why he is scared of me, he starts to thrash around and sink faster than he had been before. I hurry after him and grab his arms to stop him from sinking when his thrashing stops suddenly. I notice his eyes are closed and his chest isn't moving like it is supposed to. I bite my lip. Oh, please don't let him be dead I pray as I wrap my arms around him more securely and begin to swim towards the surface.

When I get to the surface I take a small peak to see if the ship is still there. I breath a sigh of relief when I see that it is not. I force the mans head and shoulders above the water and I stare at him, waiting for him to start breathing again. When nothing happens at first I start to panic but that panic disappears the moment he suddenly starts spitting water out of his mouth and gasping. I keep a strong hold on him, not wanting him to go back under as he does this. It seems like he will never stop when finally he does and he leans into my chest, his head laying on my shoulder. I freeze at first, shocked, but relax and am starting to enjoy it after a while when he freezes in my arms and pulls away.

The mans silvery blue eyes are wide open as he stares at me. I smile.

"Hello," I say softly and just like that the mans eyes slip shut again. I giggle. Well that went better than it could have I think.
