My Nen Ability Is an Evil Nanny System

Qianyu Nosla awakened her Nen ability at the age of eighteen.

Specialist type, and it's called the "Evil Mom System"?

Well, it's not that surprising. Her twin sister, Neon, is a Specialist too, and her Nen ability, "Angel's Automatic Notebook," is an incredibly rare power of prophecy!

But what the hell is an "Evil Mom"...?

System: This ability's effects change according to the target's villainy score. The higher the score, the more Evil Mom points the Host gets!

Qianyu: I mean, what exactly are Evil Mom points?

System: Why not try it out first?

Qianyu: Then I'll test it on that pretty boy who's been hitting on my sister lately.

System: Warning! The target's villainy score is extremely high. Possible bug detected. Warning @_@~#×%

Qianyu: ?

System: The Host is using this ability for the first time. One-time beginner protection granted. Congratulations, Host, your ability was successfully activated!

A notebook suddenly appeared in Qianyu's hands. It read:

Chrollo Lucilfer's delicate body trembled. He let out a soft whimper, his cheeks flushed like peach blossoms, while tears streamed from his fawnlike eyes. He was truly a sight to behold!

Qianyu: I do like writing OOC fanfiction, but how come this ability's writing is even more unbearable than my own...?

Then she saw something even more unbearable. That pretty boy, who had just been holding her sister Neon's hand and gazing at her tenderly, was actually...?!

The Spider boss, suddenly caught in the crossfire: ???

There was even a blush on his face that wouldn't make it past the censors.

This is blindingly embarrassing! Qianyu was at a loss for words. What the hell kind of ability is this?!

System: Calculating... Based on the target's villainy score, congratulations, Host, you have gained 10,000 Evil Mom points!

Qianyu: Why so many?!

The Spider boss, still unable to figure out his opponent's ability, decided to retreat for now. But first, he placed an order with the Zoldyck family, targeting Qianyu, the second daughter of the Nosla family.

After that, the Zoldycks' reputation took a bizarre turn.

Grandpa Zeno, over seventy and still radiating mature charm.

Family head Silva, graceful and willowy as a delicate flower.

Eldest son Illumi, alluring and heartbreakingly beautiful.

Second son Milluki, curvy and naturally voluptuous.

How terrifying! The Zoldycks were completely helpless!

It would be such a shame not to marry someone with such a useful Nen ability into the family, so they all agreed to have Illumi pursue the second daughter of the Nosla family.

Illumi: ???

My take on a silly romantic comedy, featuring both mischief and romance!

The male leads I plan to include for now are Chrollo, Illumi, Kurapika, Hisoka, and Ging.

More can be added anytime! I can write whoever you want (looks away).
