[Single female protagonist Hermione (yandere version), invincible, daily, only the Harry Potter world, a lot of personal settings.]

[The unknown diary of a white devil]

"In 1991, I entered school, and together with the savior Harry Potter, the magic world gave me a good feeling. Magic is really wonderful.

"In 1992, I was a little bored today, so I just went out and killed a few Death Eaters for fun."

"In 1993, Dumbledore is really old and confused. How can people feel at ease if he doesn't hold power in his own hands? No wonder he is always disgusted by the people in the Ministry of Magic."

"In 1994, why is Voldemort so timid? He has been resurrected for a long time but there is no movement. Is he still the dark devil who doesn't take all wizards seriously?"

"In 1995, why did Grindelwald come out? Two generations of dark devils joined forces? Do you still have shame?"

"In 1996, he finally stopped hiding? Just right, solved it all at once. ”

Hermione: Harry! You must tell Dumbledore about this - well, you can tell Damon too.

Harry: Damon, thank you, you are the only one who always believes in me - what? You want to take a photo of me in women's clothing and send it to Snape - but - why?

Professor McGonagall: It is a loss for the entire British wizarding world that you don't participate in Quidditch!

Dumbledore: Damon, I think you are right, I made a mistake - I forgot the feelings of young people - but fortunately you are here, it seems that I can be a teacher with peace of mind, after all, this is the best for me.

Death Eater: Do you think Damon White has become more and more cruel recently? I really regret being infected with the Dark Mark...

"I once saw him pick a lucky audience member on the spot to receive a brand new heart the moment he was shot in the heart!"

"I once saw him, in a moment of extreme danger, rip open Quirrell, who was possessed by Voldemort, with just a wave of his hand!"

"I once saw him blatantly rip out the dragon's heart and lungs at the Triwizard Tournament, leaving me with a mess."

"I once saw him nearly devour the centaurs to extinction in the Forbidden Forest, where a vortex of flesh and blood appeared out of nowhere and he was extremely hungry!"

"I have seen..."

In the headmaster's office of Hogwarts, Dumbledore was wrapped in a wool blanket, holding a cup of hot milk in his hand and said with a look of despair on his face.

[Invincible + Rational + Second Setting + Nanny + The original plot has been changed, please watch with caution]

Many years later, Harry Potter, who was hailed as the greatest white wizard of this century after Dumbledore, was interviewed by a reporter.

"Mr. Potter, is the person you respect most Headmaster Dumbledore?"

Harry shook his head.

"Is that Professor Snape?"

Harry still shook his head and said softly, "From beginning to end, there is only one person I respect, and that is my teacher - Al Yaxley."

What? You're saying I'm the prophesied savior of the wizarding world? Are you sure? How about you take a look at my Ten Thousand Souls Banner before you speak? The story of an Eastern magic cultivator attending Hogwarts.
