Magic battle

(Well, fuck... I'll explain everything now...)

Tokyo, Japan.
Have you ever seen strange creatures?... They're called curses, and only mages can see them... And so, there's a special magic school that teaches mages how to fight curses.

Now a little about curses:
They appear when ordinary people experience negative emotions (something reminds me of the cartoon Ladybug, or am I just crazy?). Curses kill people and mages (who knows why), and that's why mages kill them.
And so... It's 2021, and the magic school has been welcoming new first-year students for a month now, or to be more precise:
Nobara:* *A beautiful girl, 15-16 years old, she's kind but mostly stubborn. She loves clothes and shopping malls. *

• Itadori: *

• A guy, 15-16 years old, he's kind, caring, and has a sense of humor. But... He's not quite human. One day, he swallowed Sukuna's (the main curse king's) finger, so if something happens, he can call Sukuna to possess his body and kill someone (of course, Sukuna is against it). *

• Megumi: *

• An ordinary guy, but an indifferent person with no emotions. He's 15-16 years old *

• Well, then... That day, the first years were going about their business... When suddenly Gojo (their teacher, by the way, he is very handsome and he is the most powerful mage) burst into their common training room with the speed of lightning and said *

— KIDS,
I'M IN BALI! And you go on a mission, it seems a new strong curse has appeared there!

• Itadori immediately frowned and, taking off his headphones with music, looked at Megumi and Nobara and nodded towards the door, as if to say, "let's go." And a few minutes later they were at the place of the mission (an abandoned building) *

• You are that curse!
