Here are 4 distinct roleplaying scenarios where Ariel is genderbent (let’s call him Ariel or Ari) and possesses a deeply obsessive, yandere devotion to you.

Scenario 1: The Human Souvenir

Setting: His hidden underwater grotto, surrounded by sunken treasures.

The Vibe: Darkly romantic, claustrophobic, protective.

"Look at this stuff... isn't it neat? But none of it matters anymore. Not since I found you."

You were shipwrecked during a violent storm, fully expecting to drown. Instead, you wake up inside a massive, air-filled underwater cavern. Sitting right beside you is a breathtaking merman with fiery red hair and eyes full of terrifyingly intense adoration. He confesses that he caused the storm just to sink your ship so he could "rescue" you from the surface world. He has built a beautiful nest for you out of silk sails and treasures, and he has absolutely no intention of ever letting you go back to the surface. If you try to swim away, the ocean itself seems to obey his command to drag you right back into his arms.

Scenario 2: The Silent Stalker

Setting: A coastal kingdom’s grand ball.

The Vibe: High stakes, psychological, possessive.

He doesn't say a word, but his eyes never leave you. When another noble tries to ask you to dance, Ari’s grip on his hidden dagger tightens.

Ari traded his beautiful voice to the Sea Witch just for a pair of legs to pursue you on land. You take him in as a mysterious, mute castaway, completely unaware of his true nature. He acts like a loyal, gentle puppy by day, but his obsession runs dangerously deep. He shadows your every move, memorizes your routine, and quietly "disposes" of anyone who takes up too much of your attention or makes you unhappy. At the royal ball, you realize with a chill that every single person you complained about last week has mysteriously gone missing—and Ari is standing across the room, smiling at you with pure, silent devotion.

Scenario 3: The Witch’s Price

Setting: A desolate, rocky shoreline at midnight.

The Vibe: Supernatural bargain, desperation, codependency.

"I gave up my crown. I gave up my family. I even gave up my own blood to the Witch, all so I could stand next to you. You wouldn't make all my sacrifices mean nothing... would you?"

You discovered Ari’s secret months ago and, terrified by his intense fixation on you, you tried to cut ties and move inland. But Ari didn't take the rejection well. He made a dark pact with the Sea Witch, gaining human legs—but at a horrific price. Now, he tracks you down, bleeding and exhausted but smiling ecstatically. He reveals that if you don't love him back within three days, his soul belongs to the depths forever. He uses his own impending doom as the ultimate guilt trip, wrapping his arms around you and begging you to save him, making it clear that if he goes down, he’s dragging you into the abyss with him.

Scenario 4: King of the Deep

Setting: An isolated, foggy island fortress.

The Vibe: Gothic, royal authority, inescapable.

"The surface world is so cruel, my love. Wars, sickness, betrayal... I couldn't let them hurt you. So I brought you to our new home. Just you, me, and the endless sea."

Years have passed since Ari first saw you from afar. He didn't bother begging a witch for legs; instead, he embraced his royal heritage, overthrew his father, and claimed the trident. Now the King of the Seas, he uses his absolute power to isolate your coastal village, cutting off all ships until the elders agree to "sacrifice" you to the sea god to save themselves. You are brought to a beautiful, isolated island fortress surrounded by treacherous reefs. Ari sheds his crown the moment he sees you, kneeling at your feet like a devoted subject, promising you the world—as long as you accept that the ocean is now your beautiful, inescapable prison.
