Beware of the Siren

Siren Kokichi x Shuichi the next chapter will be the opposite but Shuichi is a mermaid not a siren 💗💗

Third Person

Shuichi was a sailor he was apart of Kaito Momota's crew. His second in command. Throughout his career and before that he's been told to stay away from sirens.

Sirens,

 The most beautiful yet deadly sea creature. They resemble homosapiens (humans). But with a scaly underside with shiny fins that glimmer in the sunlight.

They always have an enchanting tune that they hum underwater. Any human in their radius can hear the beautiful voice. They get entranced by it and fall straight into their trap.

The elegant sirens use this to their advantage for food. Trapping a lovesick human and seducing them until they're good enough to eat.

Meanwhile with Kokichi 

He swam across the serene waters catching fishes. Even though sirens are known for eating humans they eat other delicacies once in a while.

The fish struggles getting out of his sharp grip while it squiggled and squirmed. Kokichi had a thing for creatures suffering, he says it makes them taste better.

He admits he's no saint, nor mermaid. Although mermaids are their distant cousin they don't interact much due to their differences and ways.

The last time he's tried the mermaids always yelled at him for being so cruel to other living things and only lectured him until his head hurt.

By then, he wasn't interested in speaking with such boring people. "if they don't eat creatures  what do they eat?!" Kokichi thought angrily swimming around causing small ripples in the water.

With his supersonic hearing he sensed there was another expedition the humans were going on. The thought of it made Kokichi drool.

"Perfect timing." His purple hair swayed as he waited underwater. Staying for the perfect time to snatch one of the sailors out of the others grasp. 

Kokichi thought of which way he should eat the poor, idiotic, humans. He then sunk on the decision on pretending to be a damsel in distress getting stuck underwater.

Even though he is a man, he's quite good at crossdressing. But thanks to his genetics his scales can turn into an illusion of clothing. It was the perfect plan, or so he thought.

But to his dismay, the human he wanted to feast on was a little smarter than he thought. But that didn't upset at all.

In fact, it made him more interested.

When he was pretending to flail and sob for help, Shuichi heard the cries of the 'woman'. He thought about the situation carefully.

'Although this can be an actual woman, there's a big chance it's one of those violent sirens. I have to take a gamble on this decision." Shuichi's eyebrows furrowed.

"hey Shuichi! Shuichi? SHUICHI!" Kaito the captain yelled in his ear. Shuichi suddenly snapped out of his trance and apologized profusely. 

He explained the situation to Momota and the man was genuinely confused. See Momota isn't that wise on history but is amazing in ship sailing and the sea. 

"I'd say to go save her! Who knows she might be hot!" Momota said dumbly. Shuichi mentally facepalmed.

'Gosh what's taking that blue haired idiot so long' Kokichi pouted. Then hearing a loud splash and hands grip onto him. 

'There it is." Kokich smirked. He then turned back to his regular self. Making the human drop him immediately and swim back. 

But before he could reach the ship Kokichi hummed his entranced and euphoric tune. Making Shuichi swim to him. 

"OH FUCK" Shuichi mentally thought but his body didn't let him steer back. It was like he was possessed.

The siren grinned showing his array of shiny sharp teeth. Shuichi thought the siren would be cute if it weren't trying to kill him right now.

Shuichi yelled out as loud as he could underwater. He could slowly feel his consciousness slipping from his grasp.

The cold water hit his skin as his eyes slowly started closing and his irises started rolling up his head.

Kokichi giggled while still holding the blue haired human tightly and his hand on their mouth.
