Jujutsu Kaisen: I Awaken Cursed Energy by Taking a Beating

[After seeing way too many unhinged Jujutsu Kaisen fan creations, I decided to join the lunatics myself. New author, new book. P.S. Everything in this story came to me in a dream. Please don't roast me if the writing's bad.]

Akutagawa Jo, a college student with all the durability of wet tissue paper, only went to a convenience store for a late-night snack. Somehow, he ended up transported into the world of Jujutsu Kaisen.

Wait, what? I'm supposed to fight Sukuna?!

Protagonist: "Please, I'm begging you. Hit me one more time."

Maki: "What the hell is wrong with you?"

Naoya Zenin: "Sniff, sniff... pant, pant... That's Lord Toji's scent."

Megumi Fushiguro: "What do you mean, you're my new mom?"

Sukuna: "What are you even babbling about?"

Protagonist: "Didn't see that coming, did you, Sukuna? This is my 'Revealing One's Hand'!"

Two female leads: Mai Zenin and Maki Zenin. [A romantic battlefield!]
