How Can an Ordinary Person Survive in the Jujutsu Kaisen World?

Thanks for the invite. I transmigrated, I'm in Shibuya, and I've become an anime character, but I don't have a golden finger. Wait, I do have one after all: a thirty-second anime preview video and some cryptic comments from the audience. Comments: Come check this out, there's a new character in this project! Comments: Ooh, she stood up! Ooh, she ran into a curse! Ooh, she's going one-on-one with Brain! Comments: Wow, I can't wait to see what happens! Wanzhi: ...Heh, I guess she'll die. So why are the comments doing nothing but hyping things up?! Where's the promised spoilers?! Where's the promised cheat ability?! I'm really just an ordinary person, please! Wanzhi: I'm done. I'll just survive as long as I can. (tired smile.jpg) But who would've thought that by just keeping her head down, she'd make it all the way to the Shinjuku Showdown? At that moment, Wanzhi silently watched the pink-haired big bad wreak havoc, then looked at the group of old, weak, and injured people around her, and at the way they were gazing at her with such hopeful eyes. Wanzhi: ...? Wait, I'm fighting Sukuna...? Huh... Seriously?... You really want me to do it? [Please read before starting] 1. The female lead is truly an ordinary person. She gets by entirely with a mouth that can bluff and swindle. 2. The pairing isn't set. Most likely one of Daddy, Gojo, or Nanami, but it could also be 27 or 285 (Why are there so many options?) 3. The timeline is the Shibuya Incident. Theme: Respect life
