Give the Jujutsu World a Taste of Sister Complex

My biological older sister is named Rika. She's the best sister in the world.

Her looks, her personality, everything about her is perfect. She's taken care of me ever since we were little. The only thing that made me feel so sad I could cry was when she got engaged to a boy named Okkotsu with a ring when she was ten... But my sister said that I'm still the person she loves most!

She promised we'd be together for the rest of our lives. She said we'd never be apart.

So even after that car accident, even though she changed, my sister still stayed by my side (and my brother-in-law's). There's nothing wrong with that, is there?

A few years later,

My brother-in-law Okkotsu was captured one day. It was only after he charged into that building alone that I finally figured everything out, including the reason my sister had become that way.

What curse?

That wasn't a curse at all.

How dare they execute my sister and brother-in-law just because of that? I won't forget this grudge against those despicable higher-ups in the jujutsu world.

Later, my brother-in-law Okkotsu was taken to Jujutsu High, and I was forced to go to Saitama by that silver-haired jerk. That bastard said he'd arranged for someone my age to be my guardian there, and that after we both graduated, we'd come to Jujutsu High together...

And this guy called 5t5 isn't just impossible to beat, he's genuinely annoying! I won't forget this grudge either!

I've decided to get stronger, then check out the higher-ups in the jujutsu world, and make 5t5 run naked through Shibuya while I'm at it.

The moment Fushiguro got a call from 5t5, he could already picture the other man's smug expression with almost perfect accuracy.

So who exactly was the person he was supposed to keep a close eye on?

Two days later, the new transfer student appeared at the front of his classroom. She smiled and greeted everyone politely and warmly, but her gaze seemed fixed on him.

"I'm Iori Eri. I look forward to getting along with you all."

She didn't seem to need anyone to worry about her like 5t5 had said. She looked so well-behaved. Megumi Fushiguro quietly watched her pull out the chair beside him and sit down. She seemed pretty gentle and friendly, too...

Then, the next day after this gentle, friendly little girl had just figured out what cursed techniques and cursed tools were, she took down a Grade 2 curse almost barehanded on the third day. Before Fushiguro could even process it, the delinquents in the area had already started bowing to her and calling her their boss...

Fushiguro: "..."

She's nothing like she looks...

This girl is completely nuts!

Notes:

Pairing: Megumi

1. Okkotsu and Rika will stay together. Okkotsu won't be put through the wringer.

2. If you compare the female lead's personality to the black-and-white factions, she's more like the Chaotic faction.

3. I haven't finished the manga, so I'll develop some plot points based on my own understanding.

4. Some characters will be spared their deaths, and the Night Parade of a Hundred Demons will happen earlier.

Theme: Live well, for the family you love and for the self your family loves.
