Commander, squad leader, battle strategist, all things you are perfect for, but fear of picking favourites ran through your brothers mind. You will never be able to be any of these things, simply because your brother happens to the Commander Erwin. Heck, you even had to work harder than you had to, to be apart of the scout regimen. You could never even make friends with anyone in your squad, because Erwin kept switching you around to the safest squad for each expedition in fear of loosing you. But you had had enough, you at least want to be a squad leader, knowing that the scouts need more squads. So, when you get switched to the Corpal Levi's squad, you asked Levi to help you out. From there feeling unfold, but you are "off limits" (to quote your brother) to anyone in the scouts, especially to one of his friends.
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.
