A Shaman from the Uzumaki Clan in the World of Naruto

Unlike what often happens in novels or comics, Reiji did not instantly gain the memories of the owner of this body.

"Well... You know, I have a terrible memory..." Reiji tried to pretend, awkwardly laughing while avoiding Karina's gaze.

"Hmph!" Karina turned her face away with a sulky expression, clearly annoyed.

Reiji could only smile faintly, a mix of relief and anxiety enveloping him.

"Everyone! Please be quiet!" A woman's voice boomed in the room.

The woman had neatly styled red hair, adorned with hairpins, and her eyes were a deep blue. She wore a red kimono with a white haori.

Her body was slim yet curvy, with fair skin, and a face so beautiful that it left Reiji in awe.

Reiji was stunned, his thoughts racing wildly.

'If this woman were on Earth, she would definitely be a very famous artist or model,' Reiji thought, still amazed.

"Starting this week, you will learn how to make Explosive Tags!" The woman suddenly announced, causing the room to fill with whispers from the children who immediately reacted.

"Oh my gosh! Is today the day?"

"Are we really going to learn the most dangerous technique?"

"I'm scared!"

"Hey, calm down! It's just Explosive Tags! It's very easy!"

"Damn! Easy how? One little mistake, and we could die from an explosion!"

While the others were busy whispering, Reiji felt a pressing panic within him.

'Explosive Tags?' Reiji thought, confused.

Reiji didn't even know the basics of Fuinjutsu, and now he had to make Explosive Tags?

A sense of worry haunted Reiji.

What if these people realized that the owner of this body was dead and that the person was someone different? This situation could lead to big problems for Reiji.

Thinking seriously about all this, Reiji decided on the first step he needed to take: understanding the basics of Chakra.

If Reiji wanted to understand Fuinjutsu, he first needed to familiarize himself with the energy that has long existed and is widely known in this world—Chakra.

Reiji bit his lip, his anxiety not subsiding.

Reiji knew that understanding Chakra was the key to surviving in this new world.

'I have to learn quickly,' Reiji thought, determination beginning to strengthen in his heart.

With small but steady steps, Reiji began to plan how to navigate this dangerous path.

"These are all books on how to make Explosive Tags! Each of you will read and study this on your own! This is the test you will face! Within one week! If you fail to make an Explosive Tag in that time, don't expect to continue studying Fuinjutsu!"

The woman's voice echoed in the room, accompanied by a sharp gaze that emphasized how serious this test was.

She began distributing thick books, each containing detailed instructions on making Explosive Tags.

"Do you understand?" the woman asked, stressing the importance of this test with a tone that brooked no argument.

"We understand, Sensei!" all the students replied in unison, their voices echoing in the room.

"Good! It's time to go home! You can leave now! Remember, don't waste time playing around for this week. Use your time to study Explosive Tags!"

With a firm voice, the woman walked out of the classroom, leaving the students enveloped in a sense of fear.

"Aaah...! I'm scared!"

"You think you're the only one scared? I am too!"

"Calm down! At least we can go home now! We have a week at home!"

"Even so, we still have to study! This is going to be really hard!"

Amidst the complaints filling the room, Reiji felt trapped in his own inner chaos.

There were too many things Reiji wanted to complain about, but they were all stuck in his throat, unspoken.

First, Reiji felt a strong urge to complain about ending up and being trapped in this crazy, dangerous world, like the world of Shinobi.
