They don't live in a castle, just a giant mansion in a gated golf community. They all go to the nearby westerosi private school, except for Jon When Rob and Joffrey Baratheon begin to fight, the whole school becomes involved. Meanwhile, Jon and Sam face the dangers at the local public school.
You don't know how or why, but you've been isekai'd into the world of Jujutsu Kaisen. Although your first instinct is to stay far away from the plot, you've been blessed with an abnormal amount of cursed energy, and for better or worse, you find yourself sucked into the storyline. You decide that you may as well use your newfound powers for the greater good, and if you're lucky, you might succeed in rewriting some of the characters' fates. But it turns out that your presence in this world is even bigger deal than you first thought, and soon, everyone wants to make you theirs.
