Hogwarts , my sister is Hermione

the next day.

"Professor Louis McGonagall is here!" Mrs. Granger shouted upstairs.

"Ah? What? Professor McGonagall? You think this is...wait a minute." Louis muttered to himself in confusion, but before he finished speaking, he seemed to remember something that he had already fallen asleep.

So he immediately replied.

"Sorry, I couldn't sleep last night. I'll come down after I take a shower."

At the same time, he quickly ran to the bathroom on the second floor to wash up.

Downstairs, the Grangers glanced at Professor McGonagall, who was obviously not surprised:

"It's okay. I've seen many young wizards from Muggle families like this before. They were so excited that they couldn't sleep after learning that they were a wizard."

Hermione nodded in agreement. Although she had not overslept, she was still a little sleepy. She had been excited for a long time last night.

A moment later, Louis walked down wearing the jacket that had seventeen runes engraved on it, and after he came down, he bowed to Professor McGonagall.

"Sorry, Professor McGonagall, I was a little too excited last night."

"It's okay, politeness is a good quality. So Mr. Granger, Miss Granger, are you two ready?"

Professor McGonagall nodded to Louis, and at the same time she felt Louis' respect for her, although she could understand these things.

But for some things, just because they are understandable does not mean they are acceptable.

And if Louis bowed and apologized to her, even if she was a little angry, it would disappear without a trace because of Louis' polite behavior.

"Ready!" Hermione replied quickly.

Lewis also nodded.

But at this moment, Mr. Granger said apologetically:

"Sorry, Professor McGonagall, my wife and I may have something to do."

"dad?"

Hermione was a little reluctant. She didn't expect that her father would have to be busy with work on these days, but after Hermione called her father.

Louis stopped Hermione who was about to say what she wanted to say next, and stood up himself and said:

"Okay, Dad, Hermione and I know, but I think you should give us some funds, right?

Because I need to buy something!”

"Of course there is no problem, Louis, but you have to remember to protect your sister. It would be great if she was half as obedient as you are. Sometimes I really wish you had come out first eleven years ago."

As Mr. Granger spoke, he handed all the pounds in his wallet to Louis and reminded him:

"Don't worry, if you don't have enough, come to me. Anyway, these are all yours."

"Thank you dad!"

Seeing Louis stop her and agreeing to her father that he would go out to work, and hearing her father say that to her, she felt helpless and made another note to Louis at the same time.

Seeing that the Granger family had arranged everything, Professor McGonagall just watched silently. She had picked up quite a few orphans.

As for these Muggle parents, she also preferred that they not follow them. After all, some things cannot be explained clearly in a short while, and some things can completely wait for the two young wizards to give them answers.

After the family finished talking, Professor McGonagall reminded him:

"Okay, two little wizards, I think we should go."

Hermione glanced at Mr. Granger, and of course she heard what Mr. Granger said just now. She hummed softly, and then took Louis' hand, as if to say, I am a sister now.

"Professor McGonagall, let's go!"

…

The Leaky Cauldron.

Professor McGonagall took Louise and Hermione out of the car.

"I have always marveled at the wisdom of Muggles who can create such objects that do not require magic to be driven."

Professor McGonagall sighed a little after getting out of the car, and then looked at Louis and Hermione.

"You two just follow me for a moment."

Louis and Hermione nodded together, because he knew that everyone in the Leaky Cauldron was very complicated, but under the management of Old Tom, it was quite safe on the surface.

But Hermione didn't know it, but after entering the Leaky Cauldron, she held Louis' hand tighter for two minutes.

Noticing the change in Hermione's strength, Louis remembered one thing. Hermione had never been to a strange place without her parents, let alone from Manchester to London, so

Said softly in Hermione's ear:

"It's okay, don't be afraid."

Hermione's face turned a little red when Louis revealed her thoughts, but she still whispered softly: "Who is afraid..."

But all of a sudden, Hermione's nervousness became much better at this time.

Then, the two of them followed Professor McGonagall into the dirty and small Leaky Cauldron Bar.

When Louis entered the Leaky Cauldron Bar, he smelled a strong smell of alcohol. The slightly dim lights were very consistent with the nature of the bar. In the bar, there were many people drinking and chatting about recent events.

At this time, a voice came from the bar counter: "Professor McGonagall, why are you here?"

"Come to pick up the new students."

Professor McGonagall's reputation is still very high in the British wizarding community. After all, she is a professor at Hogwarts, and most people in the British wizarding community are her students.

"Oh! Then I won't disturb you. I wish you all the best." Tom, the bar owner, said.

Professor McGonagall nodded and took Louis and Hermione to the small patio behind the Leaky Cauldron. Then Professor McGonagall came to the trash can and asked Louis and Hermione to come with them.

"Next, remember my actions. Just count three wall tiles on the trash can upwards, count two bricks horizontally, tap three times with the wand, and you can go to Diagon Alley!"

Professor McGonagall taught the two of them while taking action.

Louis watched as the bricks on the wall continued to shake, slowly turning from a small opening into a passable area.

Once you walk in, you'll find Diagon Alley.

After stepping into Diagon Alley, Louis heard many voices calling people to buy.

"Dragon Liver 17 Sickles an ounce!"

"Nimbus 2000! The latest broomstick Nimbus 2000 is on sale!"

"Beetle Eyes 5 Knuts a Spoonful!"

…

"Is it shocking?" Louis asked Hermione, looking at everything in front of him.

Hermione nodded subconsciously.

Professor McGonagall on the side saw that both of them had come to their senses: "Come on, you two, we still have a lot of things to buy, but before that, I think we need to go to Gringotts."

"Gringotts? What is that?" Hermione asked confused.

"Where to withdraw money." Professor McGonagall replied.

Louis remained silent. He knew that the original book did not clearly explain the world's financial situation, so it was originally a mess. In this case, as long as there is money and the economy does not collapse, it doesn't matter.

He and Hermione followed Professor McGonagall to Gringotts, which was the most "dazzling" existence in Diagon Alley. When they came to the white bronze door of Gringotts, there was a creature next to it - a goblin.

He thought that it wouldn't be long before he could show that he knew about this creature.

"Professor McGonagall, what kind of creature is that?"

Hermione's questions will help Louis solve all the unreasonable aspects. To be honest, Louis thinks that the best thing about being with Hermione is this. He never has to worry about how he knows the extra knowledge. He only needs to wait for a while.

My sister would ask questions, and then everything would make sense.

"Fairies, wizards let them manage money. You can see the details in the textbook later. I will take you to exchange the wizard's gold coins."

Professor McGonagall said, taking Louis and Hermione into Gringotts.

After entering the door, they first saw a warning from a fairy, and then the three of them came to the counter.

"Oh, Professor McGonagall, you are here to collect... Okay, I understand, five pounds per galleons, how much do you want to exchange for it, kid?"

The goblin glanced at Professor McGonagall, but then saw the two little wizards behind her, and immediately understood what Professor McGonagall was here for today.

"Hmm, several thousand?"

Louis casually said a number, but the goblin was slightly dumbfounded. It didn't expect that Louis, the little wizard, was so rich.

But the final result was good. Louis exchanged all the money given by Mr. Granger and opened a vault by the way.

Got two bags with undetectable extension charm cast on them.

After a period of shopping, the three of them came to Madam Malkin's Robe Store, where school uniforms are made.

At this moment, Professor McGonagall seemed to suddenly see something, "Hagrid? Why are you here? Could it be..."

Hagrid nodded: "Yes, Harry is here too. He is going to buy school uniforms." As he said that, Hagrid looked at a timid little boy with eyes behind him.

At this time, Louis' spirit was also lifted. Harry Potter, this is the protagonist of this work, but then again, if Harry was here, wouldn't this be the same plot?
