In the air, an old man wearing a black gentleman's wizard robe appeared in front of everyone.

After the octopus monster's black light was completely annihilated by the fire, he waved his wand in a dashing manner to remove the advanced version of the fire charm's defensive spell.

"It's Grindelwald!"

"How did he end up at Hogwarts?"

"Could it be that he released the octopus monster?"

"That's not right! If he wants to destroy us, he won't be able to protect this place with fire."

Grindelwald glanced contemptuously at the Hogwarts professors' comments at his feet, and then spoke to Headmaster Dumbledore on the ground.

"Albus, it seems that too much reputation has weakened you."

"Gatler, why are you here?"

Dumbledore propped up the stone platform next to him with his hand, and stood up and looked solemnly at Grindelwald floating in the night sky.

The appearance of Grindelwald made his brain start a brainstorming.

Although Grindelwald helped him fend off the octopus monster's attack and save the unconscious students from death, Dumbledore was unsure of the purpose of Grindelwald's presence.

Is it an enemy, or a comrade-in-arms?

"It's a nice night tonight, can't I go out for a walk? It doesn't seem like this is the time to catch up, Albus."

Grindelwald let out a black squeamish, severing the two tentacles that the octopus monster had pounced on him, and then said to Dumbledore with a look of surprise.

"I didn't expect that we would have the opportunity to fight side by side."

Dumbledore chuckled and sighed. Then he raised his Gryffindor sword and Elder Wand again and rejoined the fight.

"This tsundere old man came at a good time. Will he stay lurking at Hogwarts?"

Arthur, who was thinking about how he could help Dumbledore, looked at Grindelwald's back and sighed in his heart.

"Mr. Pendragon, Miss Granger, Miss Parkinson! Come over and help."

At this time, Hagrid and Filch also returned to the auditorium with an old suitcase.

Professor McGonagall exchanged a few words with Professor Sprout and Professor Feliwick.

It was decided to transfer the unconscious students to the trunk space, which was infinitely magnified by the Traceless Stretching Spell.

Professors Lilith and Snape, who were badly injured, were out of danger at this point. Madam Pomfrey is taking her assistant to perform a resuscitation operation on the two.

"Merlin's beard. Grindelwald the Great Demon has actually come to Hogwarts. He's actually helping us."

Myrtle whispered in surprise as she waved her wand and led a student towards Hagrid.

"Lord Grindelwald? Do I remember in the history of magic that he was imprisoned in Neumengard after he was defeated by Headmaster Dumbledore?"

Hermione, who was locked in the cage of the void, couldn't help but ask after hearing Myrtle's heart.

"Hmph, Grindelwald has already run out. Why is your wizard's news so backward? Well, that's right! The Ministry of Magic won't tell the wizards this terrible news."

As a ghost, Myrtle may have been living at Hogwarts Castle, but the ghosts have their own channels of information.

….

More than a month ago, at the Ghost Party, Myrtle received news of Grindelwald's reappearance from a ghost from Eastern Europe.

「......」

Hermione was speechless by Myrtle, and as a Muggle-born wizard, her knowledge of the wizarding world outside of Hogwarts was still in books.

Watching Myrtle send a Ravenclaw student to Hagrid from a third-person perspective, Hermione suddenly became curious about the evil spirit that had taken over her body.

What is the origin of this evil spirit that I have never seen before? Why do you occupy your body? Why would you want to kill Harry?

Why... And so on and so forth

Haunting Hermione's mind, it was the first time she had thought about it after she found out that her body was being taken over by evil spirits.

"Professor McGonagall, George and Senior Fred, their full-body bondage spells are coming to an end. The whole body binding spell I recast seems to be ineffective."

Arthur looked at the black mud on the Wesley twins as they showed signs of breaking free, and turned back to Professor McGonagall in a hurry.

"All petrified!"

Hearing Arthur's call, Professor McGonagall slowly lowered several of the students hanging in the air to the ground, and then came to the Wesley Twins and recast a full-body binding spell on George.

After the spell that could shoot from the tip of the staff hit George's body, his body was still struggling violently, and there was no sign of the spell at all.

On the contrary, the struggle became more and more intense, and he was about to break through the restraints on his body.

"These evil monsters attached to Mr. Wesley seem to be immune to the effects of the spell..."

Professor McGonagall groaned, then raised her wand again and cast Transfiguration Charms on each of the Wesleys, turning them into palm-sized stone statues.

[In other words, it is the best way to read aloud and listen to books at present, @,.install the latest version.] 】

The spell that purifies the monsters on the two is now only Headmaster Dumbledore, and at this time, Headmaster Dumbledore is fighting against the octopus monster with Grindelwald.

Professor McGonagall could only try to use other spells to keep the two of them under control for the time being.

"Mr. Pendragon, go in too."

After the last unconscious student was sent to the suitcase, Professor McGonagall beckoned the three to the conscious three, and when "Hermione" and Pansy stepped into the suitcase, Professor McGonagall spoke to Arthur, who was standing still.

"Yes, Professor McGonagall."

Arthur glanced out the broken window, at the two who were fighting the octopus monster, and reluctantly walked towards the suitcase.

He was tempted to find a way to help Professor Dumbledore, but so far he couldn't figure out where to find an object of divinity.

"Hagrid, I'll leave you with the suitcase. You have to protect it. It's all we have at Hogwarts."

When Arthur stepped into the suitcase, Professor McGonagall let several older professors into the suitcase and spoke to the tall Hagrid.

"I will, even if I lose my life, I won't put the students in danger."

Hagrid looked at the professors standing in front of him, nodded heavily, and swore.

Watching Hagrid's figure disappear into the distance, Professor McGonagall withdrew her gaze and turned to the other professors.

"Now is the time. Hogwarts School of Witchcraft and Wizardry shouldn't be guarded by Headmaster Dumbledore alone!"

With that, Professor McGonagall raised her wand to look at the octopus monster outside the broken window, and the other professors also took out their wands and stood on Professor McGonagall.

With a loud explosion outside, the professors rushed out of the auditorium and cast their most powerful spells at the octopus monster.

With the addition of the professors, the octopus monster's attack slowed down slightly. Seeing that the monster began to defend, the faces of the crowd more or less flashed with the hope of victory.

But soon the glimmer of hope on their faces faded.
