Jujutsu's Dragon (JJK x Male Reader)

Dragons are powerful creatures who have dwelled on this earth since the dawn of time. They've existed before curses and will continue to exist after curses. They neither fear nor respect humanity, but sometimes the two species are forced to set aside their differences and work together. That was how the L/n clan was born. Forging a pact with a powerful dragon, they became one of the strongest jujutsu clans in history, even stronger than the Big Three families. They were renowned as an extremely caring family who preached the ideology that power must be used to protect and if necessary, destroy. Unfortunately, it was this very ideology that orchestrated their downfall. A thousand years after the end of the Heian era, the last heir of the L/n is taken in by a teacher at Tokyo Jujutsu High School. Filled with an abundance of negative emotions, he longs for the death of the one who drove his clan to ruin. With the power of the Welsh Dragon at his side, nothing will get in the way of his mission.
