I, Muzan, Just Want Them to Learn How to Treat Men Right

One day, Muzan (female) heard a ding in her head, followed by an emotionless mechanical voice:

[Hello, Host. I am the "Glorious Revival of Men's Virtue" System, born from the resentment of countless women throughout history who suffered under the strictures of female virtue. Host~ Let's join hands and revive the glory of men's virtue, spreading these fine qualities far and wide!]

Muzan was being pampered to her heart's content by the Upper Moons. She lazily raised an eyelid. "Why not just have those useless subordinates of mine do it? Why should I bother with this annoying stuff?"

[Ding~ Your three-day Blue Spider Lily trial card has arrived. Please check it~]

Muzan sat bolt upright on her deathbed: !!!

[If your subordinates revive the glory of men's virtue for you, then the trial card will go to them instead~ (≧ω≦)/]

Without hesitation, she said, "I'll do it! Hurry up and tell me how!"

And so she brought her six Upper Moons and transmigrated to a future Tokyo where all sorts of bizarre things ran rampant and every manner of weird creature was on the loose.

Her: ? What are all these ugly things? My eyes hurt!

[Host~ Let's join hands and begin our joyful journey to revive the glory of men's virtue!]

And so Muzan, reduced to a high school girl by the dimensional shift, began mercilessly tormenting all those lively high school boys.

"White hair! Yes, you! Walk properly. Keep your posture graceful, your steps light, and your bearing dignified!"

Gojo Satoru: ???

"Small eyes! Yes, you, stop looking around! That fringe and that bun are both hideous! And squinting at people is incredibly rude. You have no manners or poise at all. A man just needs to be handsome. What's the point of all those flashy accessories?"

Geto Suguru: ???

When she ran into Fushiguro Toji, a gambling addict who went around half-naked, abandoned his wife and child, and worked as a host at a nightclub, she was overjoyed. She could practically see countless Men's Virtue Points waving at her, ready to turn into a rain of Blue Spider Lilies and crush her.

This was a once-in-a-lifetime opportunity! She caught Fushiguro Toji and tormented him, determined to train him into a good man who respected his wife, raised his children, and cared for his family!

Fushiguro Toji, blacklisted by the host club, without a single cent to his name, with every job he'd taken ruined, and forced to go home after nearly ending up on the street: ???

Muzan walked hand in hand toward the light with her besties, Daki and Nakime. Everything went smoothly until... she met Itadori Yuji, a boy with an exceptionally outgoing and sunny personality.

Why was he smiling so brightly and happily, and why was he so virtuous?

Hmm? Why was he always hanging around her, too?

So annoying!

Well... not that annoying...

One day, Itadori Yuji acquired a "Villain BOSS Redemption System," supposedly the embodiment of the will of countless people who felt compassion and affection for tragic villain BOSSes.

[Yuji, Yuji! You have to use your love to change her! Care for her! Warm her heart! That's the only way to avoid a bad ending!]

Itadori Yuji scratched his cheek, smiling like a little sun and showing a faint dimple. "So I just have to make her happier! I'll do my best!"

[That's right, that's right! And in the end, you have to give yourself to...]

Itadori Yuji: ?

As the healing points steadily increased, Itadori Yuji gradually unlocked Muzan's past. He saw how she'd been bedridden and weak with illness ever since birth, how she'd been tormented by pain, how she'd grown tired of the world and gloomy, until she was driven to hate it... His heart ached terribly, and his feelings for Muzan began to shift beyond simple friendship...

And then... just as his System had hoped, Itadori Yuji fell for her himself, eagerly throwing himself at her, at that.

[Villian BOSS Redemption System: I am most satisfied. You're a promising pupil.]

Itadori Yuji's quotes:

"It doesn't matter that no one was there for you before. I'll spend the rest of my life loving you."

"I'll go through every hardship you suffered, right alongside you."

① Muzan Kibutsuji is gender-swapped. I don't need to explain what kind of person Muzan is, but her past and personality will include some author's original details. Her essential nature won't change: cruel, ruthless, selfish, and unable to tolerate anyone defying her. She's absolutely awful! The heroine torments nearly every hot guy! Truly torments them!! A dominant female S!!! If that's not your thing, please steer clear!!!

② This is mainly Jujutsu Kaisen! The heroine's System is her slavish lackey, giving her Blue Spider Lilies and keeping her entertained. Toss it aside after use! Enjoy without worry!

③ The male lead is Yuji. He's the male lead because he gets the most scenes, holds the redemption story, and the heroine has some affection for him. (An everyone-loves-her, all-pairings kind of story.)

④ The author is a heroine fan! The heroine is the strongest! Max level from the start! She will never be put through humiliating hardship! Dominant female heroine!!!

⑤ Not under contract. Written for love. Terrible writing, OOC, and no logic.

⑥ Detailed content warnings are in the author's note of Chapter One.

Theme: Healing hearts. Every little angel deserves to be cherished!
