I Become the Big Sister with Absolute Defense

Radiation descends, and supernatural powers emerge.

Bamboo Leaf is about to graduate from college and face the threat of unemployment. She cries tears of joy: the golden finger she's been waiting for has finally arrived!

"Thirty years east of the river, thirty years west! Ha ha! Your big sister Ye is here!"

Among a crowd of powerful rivals who can summon wind and rain or shift mountains and seas, Bamboo Leaf lands a job with the Supernatural Harm Cases Task Force thanks to her incredibly practical ability to take no damage from any supernatural power.

Her first day at work: Bamboo Leaf cracks her knuckles. "You vermin, prepare to die!"

A week later: she's handled sixty cases of elderly women using powers to beat their husbands, rebellious students flooding their school, and young women literally setting trash men on fire...

Bamboo Leaf is exhausted in body and soul. "Vermin, stay away for a while."

The vermin: "No way! We're coming anyway! Nya-ha-ha!"

While investigating clues about a supernatural-power theft ring, Bamboo Leaf and her friends are unexpectedly surrounded by a neighboring smuggling organization.

Bamboo Leaf lets out a sinister laugh. "Didn't see that coming, did you? I'm not the same healing-type tool I used to be!"

Super evolution! Absolute power negation!

Every last criminal, under arrest!

Bamboo Leaf waves her hand, signaling her friends to bring out the handcuffs!

The gang across from them mutters under their breath, "This is bad! If we can't use our powers, let's just grab our weapons!"

A fight! Awesome!

Back to good old-fashioned brawling, and Bamboo Leaf completely loses it!

That's against the rules! Against the rules!

Can she still be the big sister in this dangerous world or not?

P.S. That's all for now. I'll add more if I think of it.

Theme: Obey the law and be an honest person.
