Having transmigrated into the last bloodline of the Grindelwald family, he initially wanted to live a low-key life, but was forced to bind himself to the "Underworld God System".

From then on, the style of Hogwarts completely went astray.

"Petrify everyone? That's too lame. Come and witness the power of our Zaun petrification!"

"Want to learn the Patronus Charm? First, pay protection money to the system. Avada Kedavra can turn a melon into a rainbow color for you."

Dumbledore looked at the savior, who had been turned into a "henchman," and fell into deep thought: "This kid...maybe he can form the most cowardly villain alliance in history with Tom?"

Until one day, I was cornered by the Dark Lord, and the system suddenly prompted me—"Hey buddy, there's only one guy on the other side, call for reinforcements to take him down!"

William, an ordinary person, originally thought he would live a plain and uneventful life.

A letter delivered by an owl transported him to a magical world.

Is the protagonist in danger?

William said he didn't have time.

Has Hermione become cunning?

Hmm, and then what?

Dementor Riot?

Now we have the materials!

William never considered himself a freak scientist.

He was just an ordinary, unremarkable scholar.

[This is a lighthearted story; the protagonist has no morals or limits.]

Having transmigrated to the Harry Potter world, Charlie White is bound to the [Tyrant System].

By engaging in tyrannical behavior, you can earn Tyrannical Points and draw prizes infinitely!

While Hermione was studying her textbooks in the library.

[Ding! His Majesty's sleeping posture in class is practically a reincarnation of Hu Hai, perfectly embodying the behavior of a tyrannical ruler who "neglects state affairs"! Reward: Tyrannical Ruler Points +100!]

While Harry and Ron were training hard for Quidditch.

[Ding! His Majesty has been extravagant, purchasing all the desserts in Diagon Alley, in line with the behavior of a "tyrannical and hedonistic" ruler! Reward: Tyrant Points +500!]

Charlie casually did a ten-pull!

[Congratulations, Your Majesty, on obtaining: Animagus (Selectable Form)! +1 Free Talent Point, +1000 Proficiency in Fiendfire...]

Dumbledore: "Mr. White is the most gifted student I've ever seen, but unfortunately he just doesn't like to study..."

Voldemort: "Why? He learned the dark magic I painstakingly studied just by yawning?!"

Charlie lay on the sofa and sighed helplessly, "I don't want to either, but the system is giving me too much!"

[HP Fanfiction + Imaginative Stories + Lighthearted + Humor] Li Mu, who transmigrated into the Harry Potter world, didn't gain extraordinary magical talent or a prestigious family legacy. Instead, he went from a handsome 1.83-meter-tall young man to Harry Potter's chubby cousin. Before he could even calm down from his impulsive act of banging his head against a wall, the system issued him his first mission: eat the revolver in front of him, then kill the dark wizard who was about to arrive in Little Wheegham, Surrey.

[Single female lead, Hibiscus, a genius protagonist. The story will try to follow Rowling's original character traits as closely as possible, though some elements may be added by the author.]

Having been reborn into the world of Harry Potter, Raven only wants to live a happy and joyful life with his family and friends.

So Hogwarts gained a little badger who always acted on his whims.

Harry: Where's Raven? I want to see if he'd be willing to help.

Ron: He seems to have gone fishing in the Black Lake.

Harry: But I just checked the Black Lake, and it's not there!

Ron: Maybe he went to have hot pot with Hagrid? He always says that having a fish hot pot after swimming is very comforting.

......

Dumbledore: Raven, you should continue to create a few more spells so that you have a very good chance of getting a Merlin First Class before your fifth year.

Raven: But Professor, I don't want to continue. I've become more interested in alchemy and fishing lately.

Dumbledore: Your interests are very varied.

Raven: Yes, but I feel like fishing will be a long-term hobby of mine. Those damn fish just won't bite. I think I need to learn some new techniques to deal with them.

......

Grindelwald: You possess the immense talent of Raven, you...

Raven: Sorry, Mr. Grindelwald, I'm not really interested in the greater good.

Grindelwald: But war between wizards and Muggles is inevitable.

Raven: Let the people who should be worried about this worry about it. I'll bend over if the sky falls.

Grindelwald: ......

......

My dear grandpa is actually a werewolf, the truth behind the Philosopher's Stone, and the back-up man behind the four founders.

None of this prevents Loren from being a bastard, having fun with Seamus, exchanging experiences with the twins, and explaining the weirdness of Quidditch...

This is a story about hanging out at Hogwarts.

Loren: Look at that cat above, it looks so easy to touch.

Hermione: Heartbeat, in short, it is heartbeat.

In the dilapidated hut of the London orphanage, Professor Snape's face was so somber it seemed to drip water.

He never expected that a Muggle orphan's first words upon receiving an invitation from Hogwarts would be: "Is the tuition expensive? Can I take out several loans to invest?" [Resentment level +19!]

Signas, a transmigrator, awakens a system that allows him to absorb the "resentment" of others. Not only can he win incredible items through lotteries, but he can also directly enhance his magical skills!

You successfully pulled down Malfoy's pants...

You have successfully enraged Voldemort...

...

Hermione: Signas, that's incredibly disrespectful to the professor!

Ron: Hey buddy, you made Malfoy cry again!

Harry: Signas, how did you do that?

Voldemort: Damn it! Mudblood, what have you done...?

Signas: Actually, I really didn't mean to make you guys angry!

Originally, I just wanted to be an ordinary academic genius, planning a perfect life with science and reason. But when I was eleven, an owl told me that the world doesn't actually follow science. [Ding! Hogwarts notification detected!

Eli feels innocent: "I'm really just a good student who loves studying and researching!" This is a story about a protagonist who just wanted to develop quietly, but accidentally shocked the entire wizarding world and ascended the throne.

Hermione dressed as an HP world, but appeared in Marvel.

A mysterious magic book that makes Hermione jump back and forth in the worlds of Marvel and Harry Potter.

……

Tony Stark: It's time to study the Anti-Wizard Warframe.

Hermione: Are you talking about your ragged mantling that was torn down by whom?

Hulk: Roar!!

Hermione: Shut up and be careful I remove your pants...... Except for your weapons!

Ancient One: There are no mages on the timeline......

Hermione: Again, I'm a wizard!

Nick Fury: Where exactly are you from?

Hermione raised an eyebrow: I, Hermione, from Hogwarts!
