Naruto belongs to Masashi Kishimoto, and Harry Potter belongs to J.K. Rowling

Remember that this is fanfic and will probably have a bit of an anime spoiler!

I'm not fluent in English (I'm Brazilian), so remember to point out exactly where the error is.

I hope you like it...

When the leaf swirl dispersed, in the midst of it was...

Harry Potter was surprised and curious about what the headmaster wanted with him when he asked a house-elf to warn him that he was calling Harry into his office to answer some questions about the shinobi world without revealing that he, Harry Potter, was one. Deciding it was probably the teachers wanting to know how Professor Dumbledore got the pass to go to Konoha, and the old professor decided to have some fun in the way of it. Noticing this, the boy decided to wear his shinobi clothes and cancel his henge, which made him look like a copy of James Potter with Lily Potter's eyes. The henge hid his hair, tattoos, and scars and his weapons of choice, firearms.

Some would say he has an unhealthy love for guns, just like Anko has for shiny, sharp things and torture.

His custom Shinobi Uniform consisted of a black sleeveless top, jounnin jacket, gray cargo pants made from ANBU fabric, custom blue shinobi boots with heels, double black belt with fanny packs on it, a kunai pouch on his right leg, a gas mask. In the face and a rotary machine gun behind his waist in his back, gray arm warmers. His hair without the henge came down to his heels in three braids, and on his right arm and right side, his torso has tattoos of green leaves of various sizes. In the pockets of the jacket and pants, there were seals to store other varieties of shooting weapons.

Checking his appearance and checking that everything was in its place, Harry used shunshin no jutsu to appear among the teachers in front of the old headmaster.

"yo." Harry waved two fingers as he watched the teachers jump in surprise and live to see him.

Shocked and their hilarious facial expressions.

"Thanks for coming as soon as possible Mitarashi-san," said Dumbledore.

"Care to introduce us, Albus?" Minerva interrupted them.

"hmm... of course!" The stranger agreed.

"..."

"..."

"Then?!" Snape demanded.

"Yare yare..., Mitarashi Hooka-han is my name or Hooka-han Mitarashi in your culture. I like some things and don't like others, hm... my hobbies? I have a few, dreams for the future? I never thought of that." Hooka-han smiled with his eyes like a certain fan of icha-icha.

In Konoha, such a person felt a surge of pride wash over him like never before.

Back at Hogwarts, the professors were already feeling the urge to rip their hair out with just Mitarashi's answer. Snape was trying to invade the shinobi's mind, but he resisted the urge out of fear for his sanity. Minerva saw a younger version of Sirius Black and James Potter replace the shinobi in front of her. Dumbledore chuckled inwardly at his staff's reactions and how they seemed to want to curse the young man.

One of the more troubling reactions was that Umbridge seemed to be debating something in her mind to see how she could use this situation to her advantage, she was in Slytherin after all. Han and Albus made a note in their minds to look deeper into their plans for the school.

"...I want to strangle you so badly that there's no logical explanation for it..." 2 chances to guess who it is.

*cough*wannabe-batman*cough*

"I am a shinobi. What do you expect? That I deliver information that my enemies would kill for? If memory serves me, you were a spy for the light in your last war, you more than others should know the importance of delivering information about yourself."

"hn..."

"...hn"

"What just happened?..." Minerva wondered aloud.

"A professional scolding an amateur in the art of espionage," replied Albus.

"Oh..."

The teachers were silent not knowing what to ask the shinobi in front of them, many wondering how old he was or why he was there. Dolores finally decided to ask the questions she had been wanting to ask and which the other teachers probably wanted the answers to too.

"hem-hem... it's my knowledge that shinobi, in general, don't leave elemental continents unless one of you has some mission outside the barrier, so I'm confused as to why your kind come here."

"...You know how to insult someone who can eliminate you, don't you?"

Dolores started to speak clumsily, but Han stopped her from finishing.

"You're right to deduce that I'm here because of a contract I accepted. My mission here would be to protect Hogwarts students from threats that differ from students with malicious intentions and incapable teachers or those with other intentions..." If you could tell that that last part was a warning against the new Defense Against the Dark Arts teacher and that he would be keeping an eye on her.

"Apart from that... ensure students learn about the continents this year." Since this is my last year here, wasn't said.

"And how do you manage to observe the students?" Snape asked.

"That would be telling~," The shinobi says, interjected.

"How about you guys try to figure it out for yourself while I do my work? And let's not forget that it's already very late and we all have things to do tomorrow..." That reminder was what it took to disperse the teachers to their rooms in the castle to go to sleep.

Albus and Harry chatted for a bit and then excused themselves to their beds to have more energy for the next day.

TIME-SKIP

Dolores was going to her place assigned to her at the staff table marginally cheerful in the morning, she had contacted Cornelius before going to eat to tell him about the shinobi hiding inside the school Dumbledore had hired. While the information about him being at the school for his protection couldn't be used against the old principal, that didn't mean they wouldn't try to use that information. The woman looked around to find someone who looked similar to the ninja from the night before but couldn't find anyone who looked like that. Which made her very unhappy and angry.

Hermione was talking to Harry, showing her unhappiness that she couldn't find anything about the Elemental Continents in the library or in the catalog of bookstores she knew. Harry being a good friend only nodded at appropriate times that required it, while Ron paid more attention to his food but tried to pay attention to what his friend was saying.

Harry couldn't help but wonder how Hermione would react to the villages' military system, which made him laugh many times and made him look crazy, but he didn't much care what they thought, as he would soon be gone and would never have to go back, as the prophecy was faked in their hopes that they could defeat the Dark Lord once and for all. While the boy warms to not having met his parents, he wouldn't say he had a bad childhood if you exclude the accident with the Kyuubi, which ended up killing the Fourth Hokage in the event. Harry likes to prove he was neutral when it comes to Naruto, the new Nine-Tails jinchuuriki, but it sometimes made him feel sorry to watch the boy struggling to survive, which made him leave little charity boxes for him in hopes it would help him survive.

Harry wanted to adopt Naruto and said so to the Hokage, but the problem was that he was off the continent most of the time and wouldn't be able to take care of him. The old Hokage told him that when he finished his current mission, he could adopt the blonde, which Harry was grateful for. As much as Naruto managed to take care of himself, he was still a 10-year-old boy.

He was grateful to heaven for making contact with the blonde the first time he saw him, and Naruto wasn't against the idea of adoption, just as he understood why Hooka couldn't adopt him at the moment.
