Oh, mother

"The world needs your power!! There's an incredibly evil monster planning on humanity's downfall!"

"What? But I'm just a university student..."

You had imagined that pursuing biomedicine at japan's top university to then become a scientist would be the plan of your life. Boring, uneventful and miserable to the point where you were certain that you would die unhappy, but at least, you would have money to pass on. Though, your world is quickly flipped around when a man with hair as pale as snow and eyes blue like the purest of gems appeared in your line of sight wearing a blindfold and the uniform of people who live lives as miserable as yours.

"My student ate a cursed finger and now- he's cursed as well, with one of the worst beings there is. That monster needs to die, the only way we can do so is by having my student eat all parts of the monster and then eventually execute my student. But, my student is young and still has a full life ahead of him. Only your gift will make that possible for him"

"- however, every gift comes with a side effect. Just like how mine causes my eyes to be sensitive, yours makes it so that whatever you do, there will be a transfer of negative emotions."

Itadori yuuji was the name of the boy you were destined to save with a power that only you held- a power you didn't even know you had. You would need to wait until he eats all twenty of ryomen sukuna's fingers before using your ability on him to get rid of all of his cursed energy; but, that would come at the cost of your own happiness, of your own joy-

- thing was, you never were happy to begin with.

So, what happens when a certain sorcerer had promised a time of your life for the days leading up to your eternal pit of sadness?

"Sukuna has such an immense amount of cursed energy that it'll tear you apart"

"I know"

"I don't want you to be unhappy, not now, not ever."
