It's crazy how Nobara can single handedly change the events of JJK

The storyline of the JJK is molded in such a way that could keep her out of commission otherwise all the superficial stakes would disappear from the manga.

In Shibuya, you just have to pair Inumaki with her & consecutive butterfly effects would be crazy, first of all even in the canon event, there should be a Grade 1 sorcerer or someone at least stronger than her to accompany her when Maki told her to leave cause why they wouldn't think for a second that someone strong (even a grade 2 spirit) could easily kill her

Anyways just as I suggested, Inumaki got paired with her and they encounter Haruta, Inumaki being semi grade 1 sorcerer ask to rip off his finger and Nobara hits it with Resonance, well Haruta is done(even if he doesn't , Nanami beats the shit out of him) and Nanami told them both to leave.

During the Mahito clone encounter, after getting hit by Nobara's resonance, clone tries to run and Inumaki stops him, Nobara spams Resonance on him and original Mahito get far more weaker and get exorcised by Yuji and Todo duo.

Don't want her in culling games? Yeah transport her to Malaysia with Mei Mei or let her go to her hometown and meet her best friend.

During the Gojo vs Sukuna, just let her spam Resonance on Sukuna's finger giving Gojo enough time to kill him or Angel Jacob Ladder/Higurama executioner sword to work.

Voila! Gojo is alive, choso is alive, Yuji isn't traumatized as much as original storyline, Yuta doesn't have to use Gojo's corpse. Also this is not me taking into account that if Nobara actually get trained offscreen if she went to Malaysia with Mei Mei and she finally understand the "core" of the energy (which she was desperately trying to reach before getting comatose) and her Resonance end up doing more soul damage.
