Male protagonist and female protagonist, no CP.

【Important reminder: This book is serious! 】

[Reminder: The title brings a smile, but there is no smile originally! ]

Traveling to the world of Harry Potter, as the youngest girl of the ancient Black family? And having a powerful magical talent?

But what if your knowledge is limited to one or two movies you watched many years ago?

Don't worry, it's just children's literature, with just a few tropes...

No, this is different from what I expected!

You say I'm the Heir of Slytherin? No, no, whoever wants to go can go. You already have magic, why are you still playing tricks on a bunch of bugs? If you have that much free time, you'd be better off studying the practical application of Hermetic Runes in the Hohenheim Model!

Connections? Wealth? Power? These things that the world considers real are but illusions. And magic, a power considered imaginary, has become the only reality!

Human power is limited, but magic is endless.

Many years later...

Wizards praise her name in their prayers, calling her the Demon King, the Lord of Wizards, the Apostle of Arrogance, the Dominating Witch, the Man closest to God and the God closest to Man.
