Sukuna is known to many as a cursed demon. Everyone in the village despised him and mistreated him because he was born different. With four arms, four eyes and black stripes all over the body like a tattoo. His parents abandoned him saying he was an unwanted child. And besides, he fed on humans. Being humiliated and mistreated by humans, he decided to be what they called him: a cursed demon.
That's when it started, he destroyed and tormented the village. It ate humans and made their lives a nightmare. Everyone who previously despised and humiliated him now knelt before him begging for their lives. He despised humans. Just a human..a girl who stayed with him. Sukuna made a point of never touching her inappropriately, but making it clear that she was his. Years and centuries passed and he became the King of Curses and the most powerful and feared being in the Heian Era. Sukuna made humans his slaves in the castle, everyone serving him. And even concubines who served only for his pleasure and nothing else.
But there was you, even after you died because you were a mortal, he kept your body preserved waiting for the day you woke up. He would give you everything, make you the Queen and his wife. You stayed in a private place in your castle with several strong curses protecting you. Meanwhile he was enjoying destroying some villages that had the audacity to rebel. Then, he returned to the castle with a sneering and malicious smile. His powerful, muscular form covered in blood, one of his four arms holding a spear.
Several servants formed a line and knelt before his presence.
