It's the new school year. Hermione Granger, who returned to school after summer vacation, welcomed the Muggle Studies class she had been looking forward to. The enlightened Professor Lewynter showed movies in class, but these movies... seemed to be a little wrong.

Azkaban Redemption

Sirius Black: You know some dogs are not meant to be caged, freedom shines in every strand of their fur.

Infernal Affairs

Wormtail: You undercover guys are really interesting, always meeting in the cemetery.

Snape: I'm not like you, I'm honest.

Wormtail: Give me a chance.

Snape: How can I give you a chance?

Wormtail: I had no choice before, now I want to be a good person.

Snape: Okay, tell Mad-Eye and see if he tells you to be a good person.

Wormtail: That means my death.

Snape: Excuse me, I'm from the Order of the Phoenix.

Wormtail: Who would believe that?

Memento

Bertha Jorkins: Someone has been messing with my memory. At first I just forgot the afternoon, then I started to lose track of dates and what I had for breakfast…

I wanted to visit my aunt in Albania before I lost all memory of her, and Mr. Crouch was very considerate in granting me this leave.

Crouch?

I seem to remember something, a great secret.

Danger is approaching.

Now,

who I am?

Where am I?

"Come with me."

"I'll be your teacher before you enter Hogwarts, introducing you to the vibrant wizarding world and all sorts of wizards."

"I'll teach you everything I know: potions, spells, transfiguration, even the Dark Arts."

"And if one day you grow up to be a truly great savior, then point your wand at me."

"Use all the methods I've taught you, use all you have, and kill me!"

"Do you have the guts?"

"Lily Evans and James Potter's son—"

"Harry Pott!"

In a narrow alley drenched in rain,

Severus Snape, with smooth, fresh, non-greasy black hair, holding a black umbrella, reached out his hand to the nine-year-old savior of the wizarding world, who sat on the ground, his face filled with fear and bewilderment.

On the day he turned 11, Tom Riddle received his acceptance letter to Hogwarts, and his soul merged with a traveling soul from our world.

A new Tom Riddle is born, and he will take the wizarding world by storm.

With future knowledge and some creativity, he will achieve anything he sets his mind to.At the same time, he is also in the world of the Marvel Cinematic Universe/X-Men.

No harem, by the way

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.

After traveling through the Harry Potter world for seventeen years, Whitefall, who could only use dark magic, was expelled from Hogwarts and became a Death Eater. He was later imprisoned in Azkaban for helping Voldemort.

With no other options left, he took out his wand and was about to commit suicide.

As he was about to die, he heard a golden light explode in his head.

[Ding, your Infinite Forbidden Spell System has been bound.]

No, I was already in Azkaban, and Goldfinger only came?

When he woke up again, he had returned to the scene seven years ago.

At that time, he had not yet entered Hogwarts and was surviving in the cracks of an orphanage.

With the help of the system, Bai Yun uses power far beyond black magic to reach the pinnacle of magic.

If he were to live his life over again, he would make the entire magical world submit to him!

"Auror? What does your arrest of dark wizards have to do with me, the Forbidden Spells Master?"

"Death Eaters? Do you think a mere Voldemort is worthy of my submission?"

"Defense Against the Dark Arts? Sorry, I was instantly killed by a forbidden spell!"

In this life, Bai Yun officially opens a new era of the magical world with his memory and golden finger!

Harry: It seems my classmates are more dangerous than Voldemort?

Dumbledore: Our house has opened Azkaban?

Voldemort: You are using my words!

[Cyberpunk][Harry Potter][Dual World Shuttle]

Harry Potter: Old man, the work is done, give me the money

Dumbledore: Harry, 60 points from Gryffindor for your bravery.

Harry Potter: Damn it, I almost died there, and you just give me some extra points and that’s it?

Dumbledore: ...

Malfoy: Pott, you shouldn't be hanging out with those mudbloods, the disgrace to purebloods.

Harry Potter: Go away, company dog, oh no, puppy

Priest: Harry, I have a big order that I think you can take on.

Harry Potter: Dad, don’t you always ask me to handle your big orders internally?╮(￣⊿￣)╭

V: Harry, you, want to go to Arasaka Tower with me and cause a scene?

Harry: You hit the nail on the head. Let the year 2023 bring back the past, V. Let's burn Arasaka Tower to ashes!

Mann: Harry, how are you? (He leans forward) Um, that soothing agent you have...

Harry: It's the soul... Never mind, I'll give you a 30% discount for Rebecca's sake.

Rebecca: Harry, explain why you stood me up last time, honey~ (pulling out the iron gall)

Harry: I, um, I said I traveled through time, do you believe it... Don't load the gun!

Left at his aunt's doorstep, baby Harry Potter arrived in Night City after a mishap. Raised by Father Sebastian, he became a "special" mercenary for the Valentino Gang. But after a mission, he traveled back to his original world, and a line of small words appeared on his prosthetic eye: Shuttle Energy, Accumulating...

Sylby Krios's childhood was filled with cold metal and endless criticism. He always wanted to escape from this home. After secretly learning the family craft, he finally received a letter to Hogwarts.

"The Days of Child Labor in the Wizarding World"

“It’s not some animal translator.”

"My roommate is the future Dark Lord"

"Magic wands know not to do things they don't like."

"The thing that is wrong with cutting is definitely not the cake"

"Is it wrong for workers to be saviors?"

[Not Long Aotian, all characters have high IQ] [The protagonist can manipulate various natural elements] [Daily + combat is exciting!] [The character settings are not changed, respect the original work but there will be secondary creations] [Voldemort has been strengthened] [Contains various anime elements, welcome to enjoy ~✌︎˶╹ꇴ╹˶✌︎]

The regrets that have been made up for are shown at present: Harry and Neville have a complete family, and Dumbledore's sister is not dead.

A traveling soul comes to this fantasy magical world to make up for some regrets.

[HP fan fiction + no system + slow to warm up + funny and weird + single female protagonist]

Neos lost his soul during the journey through time. He was smart and made a new body for himself. Although it has no soul, it is enough!

———

Dumbledore: What is this?

Neos: A demon, what else can it be?

Dumbledore: Huh?

———

Snape: You must stop using the power of the demon!

Neos: But... we... are wizards...

Snape: What's wrong with wizards?

Neos: Of course wizards have to play with demons. They can't go to angels or people from the church, right?

———

Harry: Neos! Azazel used strange magic on me again!

Neos: Didn't you say you wanted Snape not to target you?

Harry: There's no need to turn me into a girl!

Ron: Yes, just turn Harry into a girl in the potions class.

Hermione: Hurry up! Class is about to start!

———

Azazel: If the sacrifice this time is still a pig's trotter or a pinkie, don't blame me for being passive.

Neos: Here, piglets.

Azazel: Asshole! I've had enough! Why is it always these things?

Half an hour later Azazel: The piglets are delicious.

"Albus Dumbledore made two great mistakes in his life: one was Tom Riddle, and the other was Jim Lynch." Jim Lynch, the "Mist Hangman," a forbidden legend who hunted hundreds of dark wizards, was locked in the Forbidden Forest by Dumbledore himself. When the savior Harry enrolled in school, he tore open his cage and returned to the wizarding world as a professor. Dumbledore regarded him as a hidden danger, and the Ministry of Magic became his chess game, with death walking with him. When the sky of Hogwarts was set on fire, Lynch stepped out of the fire and smiled elegantly at Voldemort: "Hello, Tom, did you miss me?"
