The cursed Dragon (Jjk x Oc)

A long forgotten jujutsu Family that fought like many others against sukuna to seal him. All members died besides one little boy, in this family 2 powers get passed down. First, pure golden eyes that reduces the cursed energy being used for techniques close to 0 (ik its like six-eyes), are giving insight in enemy techniques and make every opening/weakness seeable for the owner. Second, the draconic technique, this technique can use both prositive and cursed energy for attacks, the user can transform his body partly or fully to that of a giant Dragon. After everyone he loved died he traveled around the world and helped people in need. He wanted to help as many people as possible before he someday dies, however after he turned 21 he stopped ageing. He wanted to die, but couldn't, knowing there may be people who still need his help held him back from takes his own life. In the end he chose to cast a spell upon himself that sealed him for 1000 Years. Waking up again in the modern world he helped people once again, this time without needing to even use his Techniques. Without the need to use it and still being able to help made him happy. That continued until one day the curses once again became a great treath to humanity.
