Hetalia X Mermaid!Reader : Swim!

Drip drop, drip drop. A sound of water nearby. You found yourself in somewhere dark, damp and humid. There was darkness surround you, so threatening, so dark. There was nowhere to walk to, nowhere to run. There was just you and the dark. You feel small and scared, needing someone to save you. But your parents, your family isn't here now, your sister was sick and you have to fi-
Wait, you wasn't supposed to be in this kind of place.

You opened your eyes to see water surround you, you was slowly going down to the deep sea and quickly swam up to take air. Yes, take air. Because you had human legs now, your lungs is the same, you can't breath in water like you used to. You guess that what's make you more like a human when you disguise yourself.
Okay, this is not the time to think about it. You reminded yourself as you looked around to see devil mermaid swam at you at high speed. Yep, this is not good at all. Someone help me!!!!!

And so you swam your best with your little feet from the one with tails and fins. Not a very easy task since they had the whole advantage. Not to mention there were some shark nearby too. You had to throw a few of your knife at the mad mermaid the slow them down. Of course, being the panicking person you are, the knife only give them a few scratch and some of them even the pick it up and continue to chase you. That was not a very smart move.

Meanwhile, the people on the ship was panicking and tried to get you up but the devil mermaids kept interupt. Someone had a idea to jump down to save you but that idea was quickly shot down. Then they started bickering, you could heard Arthur and Francis shouting at each other, Lovino cursing and Feli crying. You mentally facepalmed at the sight while actually find a way to back on the ship again.

There was a ladder that the devil mermaids had missed and you climbed on it while screaming for people to pull you up. Yet, they didn't hear you at all over the bickering.
Ok, this isn't gonna work isn't it? So, you scream for the ones on the ship to cover their ears and hoped they heard you before looking down at the mermaids and screamed.

Some of the normal mermaids had very strong vocal voice that can break things or lure someone to sleep.
