It's a sunny day at cerulean city,at the cerulean gym,misty is training with her water type pokemon,after a while,misty decided to take a break.
Misty:whew! After a long training session,time for a well deserved break!
As misty reached her hand to a bottle of water and starts drinking it,a black haired young man enters the gym and walks towards misty.
???:hi misty!
Misty:oh hi ren!what brings you here? I thought you are on break today.
Ren is a janitor in the gym who cleans up the gym every night,what misty didn't know that he had a crush on her.
Ren:I have a gift for you,I hope you enjoy it.
Ren then took out a small black box and gave it to misty.
Misty:oh! why thank you!
Ren:well I gotta go! I see you tomorrow,bye!
Misty:bye!
Ren then left the gym and misty opened the black box,it was a silver necklace with a blue stone in it.the blue stone has a mermaid carving in it.
Misty:wow! How nice of him! this necklace is really pretty! I should wear it after my training.
Meanwhile,ren was walking outside smiling with a grin.
Ren:you will be mine tonight...you will be...
Back at the gym,While misty was training,misty wasn't aware that blue fish scales starting to grow on her vagina.
Misty:why is my vagina so itchy all of a sudden?
(At night)
After training misty was taking a shower while the blue scales keep growing on her vagina,now,blue scales started to grow on her ass.but she didn't realize just yet. then,Misty left the gym and wore the necklace that ren gave it to her and walked along the beach.
Misty:ahh,I love the feeling of the sea wind blowing at night!
Then something caught misty's eye,a note in the sand she picked it up and read it.
'To my dear mermaid misty:
I have been watching you,and you have been my choice for a beautiful mermaid,I will give you the gift from the sea,the place you should belong.'
Misty:mermaid? I know I cosplay as one back at the gym but this guy really thinks that I am a real mermaid?
Then a flash of blue light is shining from the cave next to the beach,which got misty really curious.
Misty:what's that?I should go check it out.
Misty walked closer to the cave,and arrived at the entrance.and the light shined brighter.
Misty:hmm...I should go deeper.
Misty took off her clothes leaving her with her one piece swimsuit,she dived into the water and swam deeper into the cave. Now,misty's feet started to turn blue and webbed,also misty heard a voice,calling for her.
'Come to me...come to me my mermaid...'
Then misty saw a mysterious figure swimming towards her,misty tried to swim away,but she got caught by the creature,he or she wrapped it's tail around misty's legs and misty's necklace started glowing.
'I have you now misty...my mermaid...'
Misty's felt her eyelids getting heavy and her legs started to feel weak she fell asleep before blacking out.
Misty wake up feeling confused she looked around her surroundings,she was on a little island surrounded by water in a cave.
Misty:where the heck am i? Huh?
Misty looked down,she realized she her swimsuit is gone,she only has seaweed covering her boobs and she was butt naked.she covered herself up embarrassingly.
Misty:m-my clothes! Where did it go?!
Also now that she's butt naked she saw that her vagina and ass has blue scales growing on it.
Misty:eeek!!! Why are there scales on my vagina and ass?!
Misty also realized her feet is now blue and it's webbed.
Misty:and what happened to my feet?!
???:that's my doing...misty...
Misty turned around and saw a familiar face in the water,it's ren!
Misty:ren?! What are you doing here?!
Ren: I'm the one who brought you here,misty...
Misty:you brought me here and took off my clothes?! Why?
Ren jumped from the water and landed next to misty,he revealed his whole body which shocked misty,his lower half didn't have legs,instead a black fish tail.
Ren:i'm actually a Merman,and you...will be my mermaid wife...
Misty:A mermaid wife? I won't be anyone's mermaid wife!especially you! You freak!and can you explain what's happening to my body?!
Ren:remember the necklace i gave you? That's the reason why,that necklace has the power to turn humans into mermaids.
Misty:return me to normal this instant!
Ren:oh yeah,the effects won't go away,I can't return back to normal,meaning you are now destined to be my mermaid wife…
Misty:I told you! I will NOT be your mermaid wife!
Misty tries to run away but ren grabbed her and won't let her leave.
Ren:oh you will...and I planned everything...
Misty's necklace started glowing,and she started to have a headache.
Misty:ahhhh! My head! It hurts!what are you doing to me?!
Ren:I am wiping away your memories,you will be reborn as a the most beautiful mermaid in the sea,just relax,and forget everything...
Misty's memories started fading away in her head,her life,her friends and her pokemon, all are fading away.
Ren:remember,you are misty,my beautiful mermaid... you are born to be the most beautiful mermaid in the sea,now rise! Mermaid misty! rise!
Misty:ahhhhhhhhh!!
With one last painfull yell,misty's old memories are all gone,misty the human is no more.
