[Harry Potter] The Grindelwald-Making Machine

He transmigrated into the original Harry Potter story wearing the skin of his game character, whose name was...

Xavier Dumbledore Grindelwald

The child of GGAD.

A child created by a blood pact and Dark Magic.

He was convinced that his transmigration was Merlin's gift, giving him the chance to save so many people from tragedy.

So, with a card System at his side, he set off to Hogwarts!

He wouldn't let a single tragedy he could prevent slip by.

A summer's love, repaid over an entire lifetime.

So cruel.

I and my love died in the tower. You and your heart were buried in midsummer.

So tragic.

Not for the greater good.

Just for the GGAD.

Little skit:

1.

What do you do if you accidentally guess the Headmaster's Office password?

Naturally, you chat with Dumbledore (crossed out) make things up (crossed out) revise the story (crossed out) have a heart-to-heart.

Dumbledore, let me tell you what Hogwarts will be like a hundred years from now!

(Pulls up a clip from NetEase, showing a duel with green light flying everywhere.)

Dumbledore: "!!!" Tom, this is the glorious world you wanted.

Xavier: The reason it all happened was that so many people died in the final battle, twisting hatred and human nature. So I, Xavier Dumbledore Grindelwald, came back to save everything!

Dumbledore: Then why is your name...?

Xavier: An accident, an accident. GGAD is true love. I'm just an accident.

2.

What do you do if you're accidentally transported to Nurmengard?

You know the Avada Kedavra, Crucio, Legilimency triple combo?

Don't kill him! He's sworn to fly the banner for GGAD!

"Headmaster Dumbledore asked me to give you his regards."

3.

Well, that Boggart is quite a surprise.

He walked out of the cabinet wearing modern clothes, a book in his hand.

Harry Potter and the Philosopher's Stone

And a broken blood pact.

Aaaaaah! Boggart! Fine, you can try to make me think this world is fake, but how can you use my ship to stab me in the heart!!!!

You can take my head, you can spill my blood, but my ship will not get a bad ending.

"Riddikulus."

Young Grindelwald and Dumbledore appeared together behind a cloud of white smoke, smiling and speaking in unison:

"Welcome to the wizarding world."

Also known as:

Is Every Blonde with Heterochromia a Grindelwald?

Did GGAD Get Their Happy Ending Today?

Give Me Back My Blood Pact, You Boggart!
