Niko x fem!reader x Crystal

You never imagined you fall in love with a human, nonetheless two human girls. They’d found you during there case on Angie the Angelfish. Initially the dead boy detectives believed that you, the only mermaid that resided in the mermaid lagoon that connected to the sea were to blame.

They had quickly captured you in an enchanted net and questioned you rather sharply. Unfortunately for them you had an alibi, you had been entertaining a group of Port Townsan’s children after they found your Lagoon.

Fortunately for the dead boys you were kind enough to help them with there problem, especially because many of the children you knew would be going to the kite festival. As you helped you bonded rather quickly with the white haired girl, Niko Sasaki.

She was sweet and so bubbly. She always asked you questions about your lagoon, your tail, how your hair was always dry. Her girlfriend however didn’t seem to like you every much. She was always moving away when you came close. After Charles threw the Nightnurse off the cliff you thought they would no longer need you.

But Edwin, the very tall and pale dead boy insisted that you remain with them just in case they had any need of a mermaid. Niko let you move into her room above the tongue and tail shop.

It’s often you don’t sleep at night, to many nightmare waiting to happen. Mermaids don’t exactly need a lot of sleep anyways. On one of the many nights you stand on the roof you find Crystal there. Her eyes red and puffy, her hands shaking gently.

She obviously did see you, or hear you. Slowly you approached her, placing your own incredible soft hand on her. She jerked her body slightly as she looked at you. She went to wipe her tears but you were faster.

You gently brushed your thumbs under eyes with a gentle smile. You’re perfect s/c skin shinning iridescently under the moonlight. She doesn’t stop crying, her body continued to shake. You brought her into your chest slowly rubbing her back.

Upon one summer's morning, I carefully did stray Down by the Walls of Wapping, where I met a sailor gay

You weren’t sure why you started to sing to her. Maybe it was because this was what your mother had done for you once. When you fears became to great and you couldn’t sleep.

Conversing with a young lass, who seemed to be in pain Saying William, when you go, I fear you will never return again

My heart is pierced by Cupid, I disdain all glittering gold There is nothing can console me, But my jolly sailor bold

Her breathing started to calm as you lulled her away from her horrible thoughts. Her hand found it way above your racing heart. You’d never held someone so close before.

You hadn’t held anyone in so long. The feeling of her warmth pressed against your colder body was nice. Strange in a way you couldn’t explain.

After she’d calmed down she looked up at you. Her eyes were red and puffy but no longer it a river of tears fall from them.

“Are you alright?” You keep your voice calm, almost hypnotic.

“Yeah… sorry I just,” She didn’t need to finished.

“Got too crowded up there?” She nodded her head. You didn’t move, you kept your arms around her.

“You may not know this but I have this demon in my head and he’s… he won’t leave me alone.” You brought your lips to her forehead, kissing her gently.

“Nightmares are the plague of sleep. A curse I only know too well.” You told her with a smile.

“Crystal?” Niko’s gently and sleepy voice came from the roof door. She stood in her pink silk nightdress that was covered in flowers. You felt your face flushed at the position you been caught in.

This was Niko’s girlfriend, your friend’s girlfriend. Niko had been the first person to show you kindness and believe that you hadn’t been sing people to death. She was the first person to cut you from the boys net and here you were. Holding and kiss her girlfriend.

Niko approached quickly and sat by your side. She nuzzled her way into your arms and wrapped her own around Crystal. You didn’t move, not wanting to bring any attention to your own racing heart.

“Why don’t you come get me?” Niko asked softly.

“Didn’t want to worry you, either of you.” Crystal voiced. Niko smiled at her and moved her face to you. She kissed your cheek with her surprisingly soft lips for someone who’d probably just woken up.

“I knew you liked us.” Niko whispered as she rested her own head on your chest. You stiffed up, your shoulders going ridged. Your face became hot as Niko giggled.

“How did you…..?”

“Wanna hear a secret?” Niko’s voice was chipper. You couldn’t move your mouth.

“We like you too.” Crystal finished.

………………………………

The water ripples around the teal shimmering tail attached to Y/n as she rests on the shore of her lagoon. Her two lovers sat on two large boulders to keep out of the water. Y/n brought her body between the pair as Niko continued to speak.

“And the cafe I found has crab for you Y/n!” Niko cheered as she kicked the water. Crystal chuckled as she took the shell from Y/n. It was a pale blue in color, matching the thick coat she wore.

“Niko that sounds lovely but you know I have to go to Atlantic tomorrow.” The two girls frown at the mention.

“I still don’t understand why you always have to go.” Niko whines softly.

“It’s a celebration for… for my dead pod. I have to go.” I mumbled softly. Crystal placed a hand on my shoulder. It was a fond memory of mine, when those hunters killed my entire pod and I had to flee in this lagoon.

“What were they like?” Crystal asked softly. I smile softly as the memories of my pod.

“My pod was an odd sort, we were all orphaned by mer-hunters. We clung to each other like the kelp that makes up our breeding grounds. We never could stray quite so far from one another.”

“Hey I’m also an orphan, well short of.” Niko added. I nod my head as I push myself up and kiss her. I run my hand through her white hair as she smiles.

“Will you sing for us?” Crystal asks softly.

Hear my voice beneath the sea, Sleeping now so peacefully At the bottom of the sea, Sleep for all eternity

Sailors live so restlessly, Come with me, sleep peacefully

Listen to this siren's song, Worry not for nothing's wrong

The two girls sat in silence as their mermaids voice rang out through their lagoon. There was no David. No annoyed dandelion sprites yelling. Just them as the mermaid sang.

Let my voice lead you this way, I will not lead you astray Trust me as we reach the side, Jumping out where men have died

Hear my voice beneath the sea, Sleeping now so peacefully At the bottom of the sea, Sleep for all eternity
