Sasuke Uchiha in Harry Potter

Slytherin vs Gryffindor I

During the DA meeting, Sasuke was reading in the library until he found a way to camouflage the Sharingan while it was activated. He discovered two interesting findings, but none that could help him return to his world.

The Colovario Charm (color change): The effect of this charm lasts as determined by the user and is a low-magic-consuming spell, ideal for costume parties.

The Vernier Charm (double speed): The effect of this charm lasts as determined by the user, but the downside is that you cannot cast another spell while this charm is activated. It was commonly used in the past to travel from city to city, but over time the charm lost popularity due to portal keys, apparition, brooms, and the Floo Network.

Sasuke was investigating in peace, as Zacharias, Hermione, Luna, and his fans were not nearby. After his investigation, he decided to head to the common room. Upon entering, he saw that everyone was discussing worriedly because Gryffindor now had two Firebolts. As soon as they saw the emo, everyone fell silent. Flint approached and asked if he had any strategies to win.

Sasuke smiled: Yes, first of all, I want everyone to learn how to pass without form. In other words, if our gaze turns to the right, the pass will go to the left, and the tactics are...

Meanwhile, the DA meetings continued at full speed. Neville managed to disarm Hermione, Colin Creevey perfectly executed the immobilizing spell after three training sessions, and Parvati Patil cast such a powerful reduction curse that she turned a table into dust.

It was nearly impossible to choose one night a week for the ED meetings, as they had to adapt to the training schedule of the three Quidditch teams, which was often modified due to adverse weather conditions. But this didn't worry Harry; he felt it was better for them to meet without a fixed schedule. If someone were watching, it would take a long time to figure out a predetermined system. Hermione quickly devised a very clever method for them to communicate.

Hermione: Do you see the numbers on the edge of the coins? On real galleons, this is just the serial number related to the goblin who minted the coin. But on the fake coins, the numbers will be changed to indicate the day and time of the next meeting. The coins will get warm when the date changes, so if you carry them in your pocket, you'll be able to feel it. Each of you will take one, and when Harry changes the numbers on his coin, because I used a Protean Charm, all of them will change to match his.

A total silence welcomed her words, and Hermione looked disappointed at the faces staring back at her.

Hermione: Well... I thought it was a good idea, she said uncertainly. I mean, even if Umbridge makes us turn our pockets inside out, there's nothing suspicious about carrying a galleon, right? But... if you don't want to use the coins...

Terry: Can you do a Protean Charm?

Hermione: I can.

Terry: But that... that's N.E.W.T. level, he commented, sounding unconvinced.

Hermione: Oh, she replied, trying to appear modest. Well... yes, I suppose it is.

Terry: How do you not belong to Ravenclaw? he asked, fixing her with a look of near astonishment. With intelligence like that?

Hermione: Well, the Sorting Hat seriously considered putting me in Ravenclaw, she said excitedly, but it ended up deciding on Gryffindor. So, does this mean we'll use the galleons?

There was a murmur of agreement, and everyone moved forward to grab a coin from the basket. Harry glanced sideways at Hermione.

Harry: You know what these coins remind me of?

Hermione: No, what?

Harry: The Death Eater scars. Voldemort touches one of them, and they all burn, and his followers know they must gather around him.

Hermione: Well... yes, she said quietly. That's where I got the idea... but you'll notice I decided to engrave the date in metal instead of engraving it on the skin of our classmates.

Weeks passed, and all four teams from the four houses were training as the Quidditch matches were approaching.

On the day of the match, Sasuke and his team were calmly having breakfast. They were confident due to Sasuke's tactics and their training. Luna approached the Slytherin table to wish the emo good luck, but everyone was surprised because the Ravenclaw was wearing a lion hat. The only one not surprised was Sasuke.

Luna: I'm showing my support for all the houses, but I couldn't finish the other hats in time. I only managed to finish the lion one.

Sasuke: Don't worry; are you not going to sit?

Luna: I'm going to sit with Ginny; she invited me earlier.

Sasuke: That's fine.

Zacharias also approached to wish the emo good luck.

Sasuke: I wish you luck too.

Zacharias walked away.

Luna: I'm going to wish good luck to my friends from Gryffindor.

Sasuke: You can come celebrate in the Slytherin common room later. The password is 'Horned Serpent.'
