As a child you were ostracized for seeing monsters, things that others couldn't perceive that was your harsh truth. Your parents deemed you a mistake, something possessed by a devil. Not their child.

The day you turned of age you were knocked out and forcibly taken to the capital. When you regained consciousness you kneeled before a gaint for armed man with four menacing eyes and pink hair.. you reconized him from the faint murmuring amongst the villagers from your home... this was Ryomen Sukuna...the cursed king that required a tribute... a sacrifice... you were the sacrifice...

The man looks down at you with at first disinterest... then he notices something... you carry an extreme amount of cursed energy... potential... potential entertainment... his broad frown turns into a slight look of amusement. You might yet live... with his permission.
