"Don't put all your hopes in the 'savior', let me carry the burden!" "Believe me, there is nothing to fear from Voldemort, he was never our true enemy!" Ethan Vincent, winner of the 2008 World War II Award

[Slytherin][Hermione is the only female protagonist][More rigorous: After living in another world for ten years, the protagonist barely remembers a little about Harry Potter][Not a system]

The false devil:

Gather the Saints to fight against the Muggles.

Occupy Britain and attack the school.

The real devil:

Destroy the world and cause great suffering to all living beings.

Elias traveled through time for eleven years and suddenly found out that he had traveled to the world of Harry Potter and was chosen by the bloodline of the devil!

You only need to gather three of the seven deadly sins: pride, wrath, laziness, greed, envy, gluttony, and ecstasy, and the power of the devil in your blood will automatically summon the devil to possess you and destroy the world!

For the peace of the world,

From that day on, Elias knew that his idle life would be gone forever...

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.

As a titan, Cabela is undoubtedly unique.

A unique body that can shrink and transform into a humanoid form

Unique timidity

When Godzilla and Ghidorah fought and destroyed her home

She: Waving her hands in protest! The two bosses probably didn't see it, so run away! Find another place to settle down

Until she learned magic (her smile gradually widened) My fellow humans, it makes sense for me to fight with magic~

As a magic school, Hogwarts certainly never thought that it would admit a monster.

Professor McGonagall: I think it is embarrassing for me to take this new student.

Dumbledore: How could that be? The child is... 20,000 Leagues Under the Sea!

As the companion of a Titan, Hermione said she was shocked that Campbell could be so soft and timid.

Canberra: Just tell me whether you like it or not!

Hermione: I love it!

(Note: This is a story with two female protagonists. The author has some knowledge about Titans, but not much. The personal settings and timeline may be a bit messy, so please don't read it too carefully. Welcome to read)

[HP Parent Generation + Child Generation + Daily Life + Taoism and Magic Dual Cultivation]

Lin Long is Lily's cousin. When she was ten years old, she was sent to the Evans family by her parents for refuge.

Growing up with Petunia and Lily, he also met a boy with black hair and black eyes.

But he didn't seem to like himself very much.

Later, they went to Hogwarts to study together.

At the beginning, she was a weakling in magic and could only rely on spells and talents to take Sirius and James to avoid the Death Eaters. Her talents and skills were also noticed by Dumbledore.

In the second year, he began to learn Taoism from Uncle Jiu, and started to practice both magic and Taoism.

But he faced the big boss Voldemort.

In the fifth grade, Snape had a falling out with Lily and also broke off his friendship with Lin Long.

Lin Long returned to China and officially began her path of cultivation.

When he returned to the wizarding world again, it was Harry Potter's first year.

When they met again, he stood in the forbidden forest, watching her drifting away like a mist in the wind, and then he said to himself: Long time no see.

CP Snape

Not a cool story! Not a cool story! Not a cool story!!!

(Note: Not against James! Not against Sirius! Not against Lily! Not against Dumbledore! Not against Snape! Not against everyone!)

(Otome + gender change + group favorite + parent-generation + multiple male protagonists + multiple endings)

What? Others who traveled through time are the Dark Lord's daughter, Harry Potter's sister, or at least a divine beast with its own system, right? Good heavens, but when I come to this place, I become the hated Peter Pettigrew?

The good news is she's still a girl, but the bad news is she has to keep her vest covered at all times when living in the men's dorm. Why is Sirius looking at me with increasingly ambiguous eyes? What? Lupin, you want to talk to me alone? Snape, aren't you madly in love with Lily Evans? And... Newt? Who are you? I don't remember your name in the book.

Watch how Alayya turns the tide and transforms from a disliked little mouse into a popular heroine!

(Note: This article involves the gender reassignment of Peter Pettigrew. Those who are incompetent should leave immediately. You are also welcome to read my other articles.)

Edward traveled through time again and came to a mysterious world.

From then on, there was a stranger here who could travel between the two worlds regularly.

So, what will he bring to both worlds?

ps1: This book is a traditional fan work and will not completely abandon the original characters to tell the story. The heroine is Miss Justice, and she may join the Queen later on.

ps2: The path of the protagonist of this book is semi-original. He takes the path of [Apprentice] in the early stage and starts to change in the middle stage.

ps3: The protagonist is basically invincible in the same level, but he can't kill high-sequence enemies.

(Otome + multiple male protagonists + sweet love + separate endings + parent generation + child generation) Lina, a male health expert, traveled through time to the magical world of Harry Potter and became Selina Lestrange, a therapist at St. Mungo's. She was also a crazy fan of Sirius Black. She took advantage of her position to go to Azkaban every day, but it was hard for her to "deepen her roots" in a field she was not good at.

See how she shakes off the label of "star chaser" and "rebuilds her reputation" at St. Mungo's! And wins everyone's love (mistake)!

Sirius: That woman has changed! How come she's still... pretty?

Snape: I don't have that disease, thank you!

Lucius: I heard that you can help me give birth to a daughter?

Bill: Thank you for your care every time

Barty Jr.: You saved me, my life is yours...

Please look forward to more male protagonists——

(The Big Bang Theory×HP. Warning to otome fans, especially those with a special madness ⚠️) Penny suddenly discovered that her bed had become a passage to another world. Every night it was connected to the beds of people from other worlds. There was always a stuffy old man who called himself "Professor" sharing her bed.

This guy had a terrible temper and a sharp tongue, and he always said things to her that she couldn't understand. And then, after an accident, she was able to see him? What's more, she could enter and exit his world?

Snape's perspective: At first he thought it was the Death Eaters who were causing trouble, but later he found out it was a curse and a calamity for him. He was the only one who could sense the damn stupid woman. No matter how many times he changed beds in the room, he could still feel her body approaching like a gorilla when he slept at night, and magic was ineffective on her. Later he could see her, and she was even more shameless to threaten him with this, the woman who only knew how to drink and eat, and blackmailed him with "beauty" magic.

He was a fool with only a pretty face, so he wouldn't fall for her trick. But as time went by, when everyone could see her, Snape always felt like he had lost something...

In his previous life, Harry defeated Voldemort, protected the wizarding world, protected Hogwarts, and became a great wizard like Dumbledore. After a long time, when he was about to leave, he thought of the blond boy. What will happen to them after their rebirth? Harry's life will also change, and his relationship with Professor Snape will also be unusual.
