A product of forbidden magic, heir to the Black and White Lords. A powerful body forged from three bloodlines, a brand new soul transcending time. The magical world is in turmoil, as two generations of Dark Lords clash on the same stage, wondering who will reign supreme.

Dumbledore said, "I am your father."

Grindelwald said, "Bullshit, he's obviously closer to me."

Voldemort said, "You are the boss, I accept your position and I won't fight you anymore."

Everything is in Hogwarts: The Forbidden Son of the Black and White Demon King.

"Extraordinary wisdom is mankind's greatest wealth. I came to Hogwarts to learn the wisdom accumulated over the years," said Blackley.

What kind of story will unfold when a new friend enters the Harry Potter story?

Dumbledore: "Oh, that little Ravenclaw kid you're talking about. He's a smart kid who's obsessed with knowledge."

Harry: "Blackley is a very reliable man, but he can be strangely persistent sometimes."

Hermione: "Merlin's lace stockings! This is the first time I've seen someone so eager to learn."

Blackley: "Knowledge is the most precious treasure in the world, and I am a goblin with an extreme greed for knowledge. So, Professor Dumbledore, can you really not explain the principle of the Killing Curse? I want to invent a counter-spell for the Killing Curse."

Dumbledore: “…”

Voldemort: "That little wizard is simply a lunatic. He actually wanted to capture me and dissect me for research! He is a lunatic!!!"

This book has many private settings. The protagonist is an orphan in this world. His adoptive father is a super ancient magician and alchemist who has lived for 17,000 years. He knows a lot of ancient magic and ancient alchemy and will teach the protagonist some, but he rarely appears and basically appears to complete the protagonist's character.

[Rebirth] [Darkness] [Decisive Killing] [Loli] [Bloodline]

The Nine Heavens' most powerful empress, Yue Lingxin, suffered an accident while traveling through time and space, and when she woke up, she found that she had traveled to the womb. After she was born, a blond woman gave her a mouthful of names: Cindy Black.

Her cheap mother was tortured like crazy, and Lucius's name was always pronounced in her mouth. In order to survive in Azkaban and to find out the reason for her rebirth, she rebuilt her exercises in her mother's womb, conquered Azkaban step by step, entered Hogwarts, and became the strongest person in this magical world.

[Single female protagonist Hermione + mainly based on the movie plot, later plot changes + system]

Kevin traveled to the world of Harry Potter and grew up in an orphanage without ever coming into contact with magic. It was not until he was 11 years old that he finally received the admission letter to Hogwarts.

Reborn, he just wants to enjoy this magical journey, but as time goes by, he can't help but get caught up in it...

Snape: Kevin? Humph! Just a cocky brat with a bit of talent.

Dumbledore: Kevin is such a good boy who would go to great lengths to help his friends.

Voldemort: Kevin, this unethical and despicable villain! He has attacked me with a crowbar every time I die!

【Reincarnated as Dudley Dursley + Power of Logic & Strength + Fixing Canon Regrets + Power-Up via Magic Item Fusion + Straight Talker (Honest and Open Schemer) + Light System (Low Presence) + No Female Lead】

A bold and street-smart man from Blue Star reincarnates into a parallel Harry Potter world…

…as none other than Harry’s infamous Muggle cousin—Dudley Dursley.

By fixing key regrets in the original story, Dudley earns the right to fuse magical items, cleverly balancing brute force and sharp reasoning, evolving from a simple Muggle into a Concept-Level Archmage.

From there—

The Savior’s dark childhood is lit by a light so twisted it loops back to righteous.

The half-giant’s beloved dream of dragon-riding becomes reality, soaring over the Forbidden Forest.

The sweet-toothed old bee (Dumbledore) stops doing faith leaps from Astronomy Tower.

The prideful little dragon (Draco) embarks on a new path of growth, with friendship taking center stage.

The venom-spitting bat (Snape) is no longer misunderstood, but ends up tasting an even deadlier venom himself.

The pink toad (Umbridge)… actually becomes a literal pink toad.

Hogwarts undergoes sweeping educational reform.

The deeply cherished dead return from beyond the Veil.

And the brutal war that didn’t even spare the birds becomes a one-sided steamroll—with full counterattacks stacked to the max.

Allen, a programmer, transmigrates to the Harry Potter world and gains the unique talent of random partial transfiguration each day.

In Flying Class, he sprouts wings.

Exploring the Forbidden Forest, he grows a turtle shell.

To heal himself, he transforms a unicorn's hoof.

And because of a transformed tongue, he develops a deep, bitter feud with Voldemort.

Elephant ears, a snake's nose, a phoenix's eyes, an octopus's tentacles, a giraffe's neck, penguin legs, a peacock's tail, dragon scales...

These transformations bring him all sorts of advantages and troubles...

They also lead him, step by step, to understand the magical essence of this world, pushing Transfiguration to new heights.

He initially just wanted to protect himself and stay far away from trouble, but to his surprise, trouble kept finding him.

Even more unexpectedly, in this magical world, he even started using programming concepts to DIY all sorts of transformed beasts...

Are you afraid of firearms that can shoot magic? What? You're not scared of those little squirt guns that only shoot "Aguamenti" and take three minutes to reload after one use? Oh, my dear customer, I'm not talking about those children's toys. I'm talking about the new big toys only big kids can use!

Please look this way:

Expelliarmus Colt! Its immense power guarantees equality for all; even Voldemort would drop his wand if hit!

Stupefy Gatling! Three thousand six hundred rounds per breath—no one can stand for more than a second under its firing muzzle!

Confringo Remington! Even Gringotts' vault door can be blown open with a single shot!

【HP】【Hogwarts】

Two years after his accidental time travel, Eric finally got his own sign-in system. So, starting from Diagon Alley, he embarked on the journey of becoming the most powerful wizard!

……

Eric: "That Minister of Magic over there, I know where Sirius Black is."

Cornelius Fudge: ?

……

Eric: "Principal, are you interested in making a deal?"

Dumbledore:?

……

Death Eater (lying on the ground) (screaming at the top of his lungs): "What the hell do you want?!"

Eric sighed helplessly: "I really just want to talk to your boss."

Voldemort:?

He was at Hogwarts, and had just become a Half-Blood Prince.

[Parent-generation; multiple female protagonists; no system]

…

In 1976, 16-year-old Severus Snape welcomed a new life.

That year, Voldemort had not yet split his soul into seven pieces.

That year, Nagini was still hiding in the forests of Albania.

That year, Pandora was still doing wonderful experiments at Hogwarts.

That year, Ms. Rosmerta was in her prime and very graceful.

That year, Snape decided to experience this wonderful world.

The life of a special wizard in that familiar yet strange world, in which we will become the protagonists.

(In memory of my infinite yearning for that magical world, in memory of the days when I used to read under the desk or in the bed!)
