On one spring evening when I was eight years old, I, Erica, Duke of Aurelia’s daughter, realized something.

Huh, I have reincarnated into a fantasy world, haven’t I?

Moreover, it was the romance-fantasy girl game that had the reputation of being bloody, 『Liber Monstrorum ~Phantom Beasts and the Winter Princess~』

The face reflected in the mirror was that of the villainess character of that game.

After repeatedly harassing many characters, including the heroine, she would die without exception, signaling the beginning of an event called the bizarre incident. She was a villain who deserved to get the consequences!

—I absolutely don’t want a destiny like that, though?

No, for me who has remembered the memory of my previous life, there would be no such thing.

In my previous life, I was harassed immensely by an irrationally angry yandere man who proclaimed ‘She is absolutely in love with me.’

My cause of death, too, was from being stabbed by another yandere man who I only had talked with a few times……

Now that I have become the haughty villainess Erica, I shouldn’t encounter more misunderstandings like with the previous life’s yandere men anymore, right……?

In that case, it will be fine as long as I deal with the death flags that I may have raised myself.

All right! First of all, before the bizarre incident begins at the Magic Academy, I will strike down the death flags accordingly!!

—Or so I thought, but it seems that I am about to die.

Eeh, how did this happen—!?

He had crossed into the dark, ruthless Wizard World.Lucien found his system somewhat different from the usual golden finger.System upgrade points? Chip activation?None of these, but rather becoming a role model, transforming into a nurturing breeze:Teaching students knowledge, receiving advanced knowledge in return.Caring for and maintaining students, earning generous rewards.[Your student has mastered the Magic Potion “Kuru's Cough,” congratulations on acquiring the improved formula “Kuru's Cough - Enhanced”!][Your student has mastered witchcraft “Fireball,” congratulations on learning witchcraft “Greater Fireball”!][Your student has successfully crafted the wizard's tool “Pale Mask,” congratulations on acquiring the wizard tool’s manual “Revised Pale Mask”!]Initially, Lucien was resistant.But after experiencing what it was like to teach disciples and outdo them, Lucien felt he had completely transformed into the form of the master system.This thing, isn't it much more useful than something called Cheating Device?
