Back when the sea was ruled by gods, the creatures of the ocean struck fear into pirates heart, a time, now a distant, foggy memory. A time before the Aroura Abyss. A ship ran by Captain Ryomen, a monstrous ruler of the seven seas. But there was a time where the horrifying, brutal captain had been a child; a time where something captured his young heart. Something no one else had believed in. A siren. Its teal tail glistened as it swam under the sea. it was the single thing he dreamt about. But now, Its a distant memory as he stays aboard a ship with his stupid, smooth-brained, quite helpful shipmates sailing the endless seas.

Satoru watches the moon, high in the night sky stars splattering across the sky like a million diamonds. He loved stargazing it was the last thing reminding him of his mother. He still has nightmares. The pirates dropping the anchor, the deep wine red staining the surrounding sea. His mother's scream. He remembers it in vivid detail. The anchor ripped open his side which scarred over, his mother getting stuck in the netting, their groping hands all over his mother body as they skin his tail of their blue scales, the way the dagger cut through her fin like it was nothing. He hated pirates after that, and his father hated him returning to the surface, that man hated human and their land.
---
But due to Satoru's lack of focus, he didn't realise the approaching danger. The Aroura Abyss. Thats when he was spotted by the Ruler of the sea, Captain Ryomen. The pirate's sharp crimson eyes widen in shock. It exists. And it was distracted. He quietly gets his right hand-Uraume-to drop the anchor and his two subordinates-Kenjaku and Yorozu- to drop the net. His dummest subordinate was to stay on the mast and stay quiet not to mess up the catch. The net was slowly brought closer and closer but before it could get the mystical siren, they had dove under water.

Sukuna's voice rung out like a bullet being shot.
Sukuna: "CHOSO, GET THE WHEEL. MAHITO, OPEN THE SAIL. URUAME LIFT THE ANCHOR."
Sukuna takes a deep breathe, as all of them get to work to follow the glow of the sirens tail before it becomes invisible, slowly dipping lower, closer to the seadbed.
Hanami: "My My, So our lovely captain wasn't completely crazy...Imagine the money selling it."
Mahito: "Be careful Hanami, what if its some sea prince, captain's been fantasizing about."

Sukuna lets out a whispered string of curses before look at the time and telling them all to head to bed before they collapse mid work. All of them walk slowly whispering jokes and humming rhymes, but one stays behind, just to check on their captain and old neighbour, Choso, a man only 5 years younger than Sukuna but 2nd youngest on the ship. His brown spikey hair put into two messy space buns fall loose his hair reaching the base of his neck. His clothes smell of sea salt and his hair is moist from the water splashing aboard the ship.
Choso:" You know, there is someone we know...Who expertized in folklore, where we grew up."
---
Sukuna thought back to where they grew up and realises who Choso is talking about, the supposed witch of their old village who would sell charms and books. He nods to Choso as he grabs a map and starts planning a course to take back to their old village. Choso grabs the wheel and changes direction while Captain Ryomen starts creating a detailed document of when noticed to try to follow a pattern...which was difficult with only being spotted twice. But in all their haste to change their path, the rest wake up and Mahito returns to the post and sees that familiar glow but instead of mentioning it he instead decides to start bellowing at the top of lung making the adored siren attempt to escape but Dagon- their most trusted fished starts throwing spears and using fishing rods one peircing his fin but he doesn't stop, refusing to be caught like that while Yorozu attempted to pull the spear back in.
---
In Satoru's haste to escape he gets to the closest land dragging his body to the nearest desolate beach his tail and fins dissolving into two slender legs, his right foot injured from where the spear stabbed him but only as a bruise as he stands up and limps away wearing a white shirt and small brown/teal shorts. Unbeknownst to him this was island his devilish pursuer was heading to, the place where his new nightmare were just about to begin, a place where people did not have self control and he lacked knowledge of what happens to pretty things on the land.
