Sasuke Uchiha in Harry Potter

Sasuke vs Sirius II

The green curse approaches Sasuke, who is unaware of it as he is focused on feeding Mrs. Norris. However, Mrs. Norris. notices the incoming green bolt and jumps to position herself between the killing curse and Sasuke.

Sasuke: Mrs. Norris! - He quickly touches her body and realizes she is dead.

Sirius casts the killing curse again, but the young man has vanished from his sight.

Sirius: Where did he go? This is impossible; you can't Apparate in Hogwarts. - He thought.

He scanned the area, searching for the emo, while Sasuke was perched on the ceiling, looking for the assassin.

Sasuke: Damn! I didn't sense his presence. Where is he? - He thought, activating his Sharingan. He looked around but couldn't see anyone.

Sirius checked the map and saw that Sasuke was still in the corridor. He then looked up and spotted Sasuke on the ceiling, hanging upside down. He was incredulous and wondered how he had gotten up there, but pushed that thought aside and pointed his wand at him.

Sasuke: If he's still here, he won't be able to escape this - he thought while forming hand seals. - Suiton: Mizurappa!

Just as Sirius was about to cast another killing curse, a large amount of water erupted from Sasuke's mouth.

Sasuke watched as the entire area was engulfed in water and saw the waves generated by the invisible assailant who had attacked him.

Sasuke: There you are. - He said as he launched himself at the figure to strike with his fist.

Sirius desperately dodged, but the cloak fell to the ground.

Sasuke: Black.

The emo wore an irritated expression as he glanced sideways at Mrs. Norris.

Sirius: Die! BOMBARDA MAXIMA!

A massive explosion occurred, raising a cloud of smoke. When the smoke cleared, only the damaged floor and wall were visible.

Sirius: I got it!

Sasuke appeared behind him and said, "No!" before elbowing Sirius, sending him flying backward.

Sirius quickly got up and cast several spells, but they were easily dodged by Sasuke.

Sasuke: Seems like it's not as easy as before, is it?

Sirius: Shut up! AVADA KEDAVRA! AVADA KEDAVRA!

But the spells were once again evaded by the emo.

Sasuke: Is that all you know how to do?

Sirius continued throwing every spell that came to mind, but none hit the emo.

He was already exhausted and panting heavily.

Sirius: Why, why, why can't I hit him? - He thought.

Sirius: LUMOS MAXIMA!

The entire corridor lit up, and he saw the emo shielding his eyes.

Sirius: Now - he thought - AVADA KEDAVRA!

Sasuke was hit by the curse and fell to the ground but suddenly transformed into armor.

Sasuke: Did you really think it would be that easy?

Sirius turned to aim his wand, but his arm was grabbed by the emo.

Sasuke: You're just a coward who attacks from behind. You don't need this arm. - And with a swift movement, he broke Sirius's arm. The wand he was holding fell to the floor.

Sirius screamed in pain, but Sasuke didn't stop; with a kick, he sent him crashing into the wall, breaking his ribs.

Sasuke: Come on, didn't you want to kill me? Get up.

Sirius: Damn you! - he said while trying to stand.

Sasuke: You know, that cloak caught my attention. It must be very special not to reveal your presence. - he said as he observed the cloak.

Sirius: STAY AWAY FROM IT!

Sasuke: I couldn't even see you with my Sharingan under that cloak. Maybe it's the cloak from the Tale of the Three Brothers. Mr. Lovegood told me about it, the Deathly Hallows. After all, every story has some basis in reality. - he thought.

Sasuke: You know, I think I'd better destroy it. - He extended his arm toward the cloak. - This cloak is a danger; it's best to destroy it. - he thought.

With his arm extended, Sasuke said, "Enton: Kagutsuchi." Black flames formed into a sword and lunged toward the invisibility cloak.

Sirius: I WON'T ALLOW IT! - he shouted with difficulty and quickly positioned himself in front of the cloak.

The fiery sword struck Sirius's right leg, piercing it and simultaneously burning the invisibility cloak.

Sirius let out a scream so loud that it seemed like all of Hogwarts could hear...

Sasuke extinguished the flames as the ashes of the cloak were carried away by the wind. Sirius was on his knees from the pain of his burned leg.

Sasuke approached and noticed a parchment near Sirius. He picked it up and saw it was a map showing the people throughout Hogwarts in real time.

Sirius quickly touched the map with his uninjured hand and said, "Mischief Managed," causing all the map's information to disappear.

Sasuke: What did you do?

Sirius: You'll never use it.

Sasuke grabbed Sirius's face and said, "Chidori."

Sirius screamed in pain as he was electrocuted and fell unconscious on the floor.

Sasuke: It's time to end you. - He said with determination as he summoned his katana, ready to finish off Black.

???: Don't kill him.

Turning around, Sasuke saw Dumbledore, Snape, McGonagall, and several Hogwarts students who had followed the screams and explosions.

Sasuke: Headmaster, good evening.

Dumbledore: What happened here?

Sasuke: The situation is simple: I'm dealing with a murderer.

As Sasuke observed everyone, he noticed that everyone was showing shock and fear, except for two individuals who revealed no emotion. These individuals were...

Dumbledore said nothing, only looking at Sirius on the floor, unconscious and bleeding.

Sasuke: It seems you and Professor Snape aren't surprised.

Dumbledore: Monitors, take the students to their respective common rooms. Pomona and Sinistra, let's escort Mr. Black to the infirmary. Mr. Uchiha, come with me to my office.

Sasuke: Wait.

Sasuke pulled out a two-sided mirror and called Minister Bones.

Amelia: Mr. Uchiha, what happened?

Sasuke: There was an attempted murder. Sirius Black tried to kill me. He is in Hogwarts now. Send a team of Aurors and come with Scrimgeour to the headmaster's office.

Amelia: I'll be there in 15 minutes.

Sasuke: I'll be waiting.

He then bent down and picked up Sirius's wand.

Sasuke: We don't want any of the evidence to disappear, do we? — He said, looking at the professors.

He also approached Filch, who was mourning the death of Mrs. Norris.

Sasuke: She was a very brave cat; she saved my life. If you're going to bury her, let me know. I want to pay my respects too, Mr. Filch.

Filch: Thank you for your words, - he said, still crying.
