By now, I'm fairly certain people know about the folklore and myth surrounding the actual Ryomen Sukuna concerning the monstrosity that terrorized Japan.

𝐢𝐧 𝐬𝐡𝐨𝐫𝐭 𝐨𝐫𝐝𝐞𝐫: Two conjoined twins ( bound at the waist and sharing the inner ribs between the two ) were treated as freaks by the entirety of their small fishing village. Even their parents were horrified by the creature that come about their union, so they sold their sons into slavery.

Though awkward in their movements, they were very, very strong. Though they were called ‘Nashi’ by anyone that bothered to address them,

The two boys had named each other in secret. The older one, Naoki ( "tree of truth" ), was the strong one in both body and personality; a boy that held to his truth even when it could land him in trouble. A trouble maker in the making, he was a prodigy in that he only needed to see something physically executed once to be able to perform right the first time. The child of great courage and great darkness held a unique sort of dislike for those that complained of their woes and never once in their lives tried to correct a single thing about it.

The younger was Asa ( "morning" ). The parasitic twin that latched onto the older one and hasn't let go, a bit weak in that he was quite literally leeching the life of his older brother through no fault of his own. A sweet child, a smart child, full of love and life but quiet. He tempered Naoki's darker tendencies that grew from the desire to fight back when wronged but grew some of his own in the way of knowing where to hit a man to make them go down through avid thirsts for knowledge. When Asa did something, he did it no matter how many times it was right or wrong. A real love for picking apart actions and results to study why and what was happening in each one.

Their relationship with one another was one that held not a single bit of hate or resentment for the other. It was a pure thing born of an older brother willing to give himself to keep the younger around for longer and the younger unconditionally grateful for the brother he has. Even when the worst came, they had each other. Through sickness, physical abuse, and the first three years of their life spent in ridicule.

He doesn't quite remember what the man who bought them at the age of five had for a name. Sukuna has lost a few of his original memories to time and the ritual itself. All he remembers about him is the smell of kareishu, sandalwood, and moss as though he spent his time in ponds or old, unsanitary, or abandoned bathhouses. He always spoke of the two as miracles, marvels of both medicine and cursed energy. Remnants of a clan wiped out so long ago by war and famine even sorcerers had scant records of their existence.

The man was from a religious sect of people, The Daisākuru, now long buried by Sukuna's own hand. They believed that gods and demons were the same; curses and sorcerers were as well. The only difference between the two was the function of these things in direct opposition to one another. Demons were divine entities that chose to do things in their own order; now it is their function to abhor and fight the gods that follow their natural rhythm. In doing so, they then create their own rhythm to follow. Curses are humans weak to influence or have weakened to this influence to be overwhelmed and deformed by power. Sorcerers are humans that do not bow to power but change its flow as they desire.

The most radical of the Daisākuru were those that believed only the gods could erase this evil they endure as both sorcerers and priests. They followed the no-faced Ebon god of chaos, and therefore, order.

Their first few years in the compound were spent training, eating, and becoming healthy. Around the same time every month, they were placed in great contests in which they were to fight other children to the death. All considered special, high-potential trainees that have been training since they were in diapers. They were pitted to the death every year of their life and the opponents only seemed to grow in age until they were fifteen and fighting men almost twice their age with far more experience. Exercising cucrses and culling competition was harrowing, but it was life. They were given food, clothing, and a place to lay their heads.

It wasn’t until they were seventeen the game changed completely. This time they were stuck in the room with men and women of all ages, a year with only enough food for them to survive for two months. Given the most food to survive on, they were targets from almost day one.

Non one knows how. No one knows what happened. The twins survived, but they were no better than feral, ferocious creatures that stayed to their own and trusted no one.

Chained to an unknown ritual circle, the twins were subjected to the ritual of binding. Every ritual performed thus far was a failure, but in the twin’s case it was a success. The Daisākuru have been trying to bind gods to mortal form since the ritual had been found almost five hundred years ago. They hoped to bind the ebon god’s face of justice to a mortal body that wouldn’t hesitate to do what needed to be. In reality, this ritual only served to introduce the hand of wrath into a ritual meant to create new entities rather than bind old gods to form.

Before they could bind the newly formed Sukuna with rites that would put him under servitude and following a function dictated by his creators, the two twins personalities were allowed to fill in the gaps. Where they wanted a mortal bound god that would destroy curses in their entirety, they allowed him to desire revenge and wrath on the humans that did this to them. A creature that cared not for human nor curse.
