Chapter 5 - E4-Okkotsu

It has been a year since they arrived at Jujutsu Sorcery School. Both he and his siblings have made impressive progress; in their master's words, his siblings were total prodigies.

Tobirama and Tsunade were the most well-known among them, literally revolutionizing the Jujutsu world with their creations.

Tobirama: The seals created by his hand were infinitely superior to the existing ones. His variant of the seals was called Fuinjutsu.

Fūinjutsu (封印術, Sealing Techniques): This is a type of technique in which one or several people are capable of sealing or storing living beings, cursed energy, or objects in scrolls, people, or any other medium of storage (explosive and storage seals, along with seals containing positive energy that can be thrown at curses).

With this, Tobirama became absolutely vital to the sorcery school. He was the only one capable of creating these Fuinjutsu seals. Later, due to his affinity with his original version from the Naruto world, he also managed to create the Shadow Clone Jutsu, which he taught to us, his siblings, and Gojo-sensei, who became very interested in that technique. As expected, Gojo-sensei learned it in just a week.

Then there is the creation of his most distinguished technique and the reason he became a prodigy: the creation of Hiraishin No Jutsu (Flying Thunder God), the only space-time technique not related to a cursed technique. This definitely earned him the prodigy status. Only two people know how to perform Hiraishin: Tobirama and Gojo-sensei.

According to Tobirama, it is a technique involving a unique seal that he uses to mark locations or targets where he would later teleport. His sensor ability only made things easier.

Currently, he has developed three levels of Hiraishin and the technique used by Minato to teleport Kurama's bijuudama: Thunder God: Thunder Guide (飛雷神・導雷, Hiraishin: Dōrai). The technique involves using the formula to raise a spatial barrier that sucks in everything that comes into contact with it. The target of the technique is teleported to another place marked with Tobirama's formula, usually located on his kunai or in distant places where Tobirama had previously left his mark.

Like Minato, he uses kunai; according to him, he feels more comfortable using them. He also adapted them to his fighting style along with his Thunder God Technique and Shadow Clones.

He became a swordsman, becoming one of the best thanks to his excellent handling of swords, which led him to create his own fighting style, a style called "Flowing Water," complemented by his speed, reflexes, and strength.

His ability with barriers and veils was impressive, being able to create his barriers and maintain them while fighting.

He also created a variant of the Body Flicker Technique (瞬身の術, Shunshin no Jutsu), an instant movement technique that involves moving the body at high speeds, allowing for short or long-distance travel at a speed almost impossible to see.

This also made him one of the fastest sorcerers, although his position was debated with Naobito Zenin.

His most recent creation is the Bunshin Daibakuha (分身大爆破), where the user uses a shadow clone as a decoy near the victim. The target, following the principle of "one attack to bring down the enemy," is subjected to a powerful explosion.

In addition, his first creation, the Shadow Clone (影分身の術, Kage Bunshin no Jutsu), allowed him to advance his learning to insane levels due to the ability of these clones to transmit the experience and memories gained to the original user. This further enhanced his status as a prodigy, rising to his current rank, which was a Semi-Special Grade, being the first in the history of Jujutsu Secondary School to create a new rank in the Jujutsu world.

Although he improved in many other things, such as in his water manipulation ritual, this was the most important thing Tobirama achieved in his first year and what led him to his current position at the sorcery academy.

Tsunade: She was another scandal of the almost-extinct Senju Clan. The only user of the reverse technique capable of using 100 percent of her ability on an external person. According to Shoko, who was the other user capable of using the reverse technique on others and Tsunade's current master, she was categorized as an unprecedented talent. She immediately became a well-known figure in the world of sorcery, as women usually did not stand out in the world of sorcery.

Her ability to regenerate lost limbs and body parts, whether arms or legs, made her a celebrity in the entire Jujutsu underworld. Inevitably, certain ears belonging to a scarred man and a god-complex man became interested in her.

Another thing that stood out was her body, not for its physical attributes, but for its unique abilities. Her body was known for having inhuman resistance, with excellent strength and senses, but what stood out the most was her monstrous resilience, even surpassing Gojo-sensei and Zenin Maki.

As for Itama, he has progressed but not as much. Itama's ritual technique is called Kagutsuchi Flames. His flames could burn all types of curses, which were weak to his flames because they were plagued with positive energy.

His abilities manifested in:

- Creation of fire constructs: The user can create various constructs from flames, such as spears, swords, wings, animals, etc.

- Pyrokinesis attacks: The user can project flames offensively in various ways, currently only from his own body.

- Pyrokinetic combat: The user can use his flames to enhance his attack power, such as increasing the impact of his blows/kicks or through projection cuts.

However, activating his ritual consumes part of his body. His left arm and eyes undergo a radical change, turning the color of flames, his skin is consumed by fire leaving only raw flesh, his eyes turn the color of fire, and his hair becomes like living flames, flowing and burning. This has a consequence: entering "Flame Mode," as he called it, causes him almost unbearable pain, forcing him to endure it if he wants to fight. He can only maintain it for 5 minutes before the pain overwhelms him. In that time, his potential rises from a Grade 2 sorcerer to a Special Grade sorcerer.

As for me, I had only advanced my wood style in several jutsus from the original Hashirama.

First of all, I had done something that benefited me enormously. In my family's house, amidst the remnants of the burned clan complex, there were still scrolls containing knowledge of Fuinjutsu, from which Tobirama copied, and explanations of some hand seals. I was forced to make a binding vow, which, for each hand seal performed, would enhance my technique. In short, the more hand seals I made, the more powerful the technique would be. If I didn't use hand seals, my techniques would be weaker but still effective.

Hand seals I learned:

- Serpent (巳, Mi)

- Bird (酉, Tori)

- Boar (亥, I)

- Hare (卯, U)

- Prana Mudra (the mudra with 2 fingers raised in one hand)(Confrontation Sign)

- Ram (未, Hitsuji), which is used for Fuinjutsu.

As for my advances with the jutsus that, for some reason, I remembered from Hashirama:**

Jutsu: Wood Clone (木分身の術, Moku Bunshin no Jutsu): These clones are generated by using cursed energy to alter the user's cells and turn them into vegetation. The clones can be as simple as replacements in the Body Replacement Jutsu or completely mobile and capable of using jutsus (in this case, incomplete cursed techniques). They have the ability to travel long distances separate from the original and communicate with him. Additionally, the user can change the form of the clone by touching it with his hand.

Wood Style: Great Tree Birth (木遁・大樹轟誕, Mokuton: Taiju Gōtan):A jutsu where I grow various branches that I use as transportation to approach the opponent. Then, I strike the ground to make trees grow that ultimately strike the opponent.

Wood Style: Wood-Dragon Jutsu (木遁・木龍の術, Mokuton: Mokuryū no Jutsu):** A dragon of wood created by the user, which uses specific hand seals to summon a massive dragon that can be directed to attack an opponent.

Wood Style: Wooden Man Jutsu (木遁・木造男の術, Mokuton: Mokujin no Jutsu): This jutsu allows summoning a huge wooden man that can be directed to attack an opponent. The technique appears as a large ogre with big teeth, and the man also has an arm that can block attacks and strike. Hashirama usually accompanies this technique with the Wood Dragon, which wraps around the wooden man's neck to immobilize the opponent and absorb their cursed energy.

Hokage-Style Sixty-Year Jutsu — Kakuan Introduces to Society His Hands Bearing Happiness (火影式耳順術 廓庵入鄽垂手, Hokage-Shiki Jijun Jutsu — Kakuan Nitten Suishu):

With this jutsu, the user utilizes the Wood Element's power to forcefully subdue a powerful curse or a high-grade curse. To invoke this method, the curse or its summoner must possess the Kesshōseki, a crystal that responds to the user's energy. The user can then produce the "sit" seal (座), which automatically appears with the technique, on their palm. By touching the cursed energy of the curse with their hand, they can suppress it within an area bordered by ten or eleven wooden pillars.

Incomplete Sage Mode of Cursed Energy (仙人モード, Sennin Mōdo):

This is the result of a harmonious union between cursed energy, physical energy, and spiritual energy. This allows the user to greatly increase their cursed energy levels, strengthen their physical capabilities, and use jutsus with a remarkable power boost.

The thick, unextracted cursed energy in this world is easy to detect; however, it's challenging to use due to the negative emotions it carries. This energy often affects my emotional state, making me easily angered and prone to losing control. I theorize that to use it effectively, I must be in a state of profound mental peace, which is difficult to achieve. Due to the cursed energy and my inexperience, I can only use it for a maximum of 2 minutes before losing control.

Secret Wood Element Jutsu: Birth of a Tree World (Incomplete) (木遁秘術・樹界降誕, Mokuton Hijutsu: Jukai Kōtan):

This jutsu allows me to create a dense forest of trees, forcing deep vegetation to grow on any surface I desire. A small plant can instantly grow into a forest through the generation of chakra (cursed energy) and user maneuvers that are convenient for both attack and defense. Moreover, this omnipotent technique allows for capturing the enemy simultaneously: with its enormous life force, the trees can penetrate through thick earth walls and extend their branches to ensnare their prey instantly. However, I can only use it within a 200-meter range before exhausting my cursed energy entirely.

Jujutsu High, Tokyo| 10:00 AM.

Six Jujutsu students walked lazily toward their boring class with their flamboyant teacher. These students talked and yelled lazily:

- Toge Inumaki.

- Maki Zenin.

- Panda.

- Tobirama Senju.

- Hashirama Senju.

- Itama Senju.

As Tobirama yawned lazily while listening to Hashirama tease Maki, comparing her to an old woman for how easy it was to irritate her, Panda interrupted after clearing his throat a bit. This routine had become common, as it seemed the only person who could get under Maki's skin without speaking was Hashirama.

"Hey, have you heard about the new transfer student?" Panda asked with a thoughtful look. Itama, walking beside Inumaki, Tobirama walking next to Maki, and Hashirama, walking next to Panda, all paid attention.

"Huh? They're transferring someone new?" Hashirama asked with doubt, his casual attitude causing Maki to huff a bit.

"They say he locked four of his high school classmates in a locker," Panda said. Tobirama raised an eyebrow, maintaining his usual stoic demeanor.

"Did he kill them?" Tobirama asked.

"Tuna with mayonnaise?" Inumaki added.

"No, but he seriously injured them, nearly killing them," Panda replied.

"He's powerful, isn't he?" Itama asked for the first time in the conversation, his voice curious. "I mean, yesterday in my training with Nanami-sensei, he didn't mention anything about this, so I doubt he knew anything, but it seems interesting."

"I sense a somewhat dark presence, but it's well-hidden. Other than that, don't be surprised when you see him; he has a pretty substantial amount of cursed energy," Tobirama commented calmly while placing a wooden stick in his mouth.

"Can you feel it from here?" Hashirama asked, surprised.

"Yes, he's accompanied by Gojo-sensei, which makes it more noticeable," Tobirama replied.

"How significant would you describe his cursed energy?" Panda asked with curiosity.

"About as large as my idiot brother's," Tobirama responded.

"It doesn't matter if he gets arrogant; he'll have to deal with me," Maki said, having been paying close attention to the conversation.

"Yeah, sure, I don't doubt you'd be able to kick his ass," Hashirama said mockingly.

Maki, annoyed, turned to him, grabbed her spear still in its sheath, and lunged at him, shouting for him to repeat that while chasing him.

In the classroom, where the six students waited bored, Tobirama tensed as he felt the familiar presence of Gojo-sensei and the previously sensed dark presence, growing more intense and approaching. With all the calm he could muster, he looked at his brother Hashirama, who was lazily sleeping at the desk, almost drooling.

"Oi," Tobirama whispered, but Hashirama did not wake. Knowing his brother's heavy sleep, Tobirama had to resort to "special" measures for special people.

Performing a hand seal, he concentrated cursed energy in his mouth and spat a bit of pressurized water, causing it to fall directly on Hashirama's face, making him jerk backward in his chair and, consequently, fall to the floor. Maki and Panda laughed at him, while a bead of sweat rolled down Itama's face, who was also watching.

As Hashirama was about to protest Tobirama's action, Gojo's presence became evident as he burst through the door with enthusiasm and joy, as if he had won the lottery.

"Alright, alright, dear students, sit down!" Satoru Gojo exclaimed energetically. "I have an important announcement to make."

With a frustrated look, Hashirama adjusted his chair and sat with a sour expression. Tobirama, on the other hand, looked toward the door, his brow furrowed and his hand on one of his Fuinjutsu seals written on one of his bandages, where he secretly kept a cursed weapon.

"Let me introduce the new student, come on, get excited, guys!" Gojo exclaimed.

But seeing the class's apathy, disinterest, and annoyance, he murmured a small "cheer up..."

To his attempts at cheering them up, Maki scoffed derisively and spoke with indifference. "They say he's a temperamental guy. Sorry, but I'm not excited about receiving someone like that."

With a sigh and his usual flamboyant attitude, Gojo spoke to the person behind the sliding wooden door through which he had entered. Moving to the corner of the room, right by a window, he couldn't help but smile.

'I'm going to ignore it,' Maki thought while crossing her feet and looking away.

The door opened, and with the first step, a boy with black hair stepped into the room. Immediately, Tobirama felt a heavy, oppressive sensation, and it was no wonder: right behind him, a special-grade cursed spirit followed. His cursed energy was dark, obsessive, and psychotic.

Everyone's eyes widened with hostility and surprise as they felt the boy's energy, who wore his own version of the uniform, consisting of a loose white jacket with sleeves that reached his forearms, while the rest of his clothing remained black.

The boy walked to the center of the class and, with a tired look and a fearful and nervous expression, spoke. "M-my name is Yut-Yuta Okkot-". But before he could finish, Toge, Maki, Panda, Itama with his short katana, and Tobirama, who had drawn his katana but was further back, surrounded him without even asking.

"Are we being tested or something?" Zenin said with annoyance before continuing. "You're cursed; we study curses here. This isn't the place for someone cursed like you."

"Disappearances and unexplained deaths exceed ten thousand per year in Japan, and most causes are curses born from humanity's negative emotions. Only a curse can exorcise another, and that's what we learn here, at Tokyo Jujutsu High," said Gojo-sensei.

Yuta's face paled, his expression said it all. "You should have told me earlier." The gaze of all of us turned directly to Gojo-sensei, who raised a hand in apology.

"Hey, if I were you, I'd move away," said Satoru, to which Panda, Inumaki, Maki, and Itama looked at him confused.

Tobirama immediately felt a fluctuation of cursed energy coming from Yuta and, with speed, grabbed Itama by his uniform and leaped away from the area, returning to where Hashirama was sitting, who had been observing Yuta closely the whole time. To this, Itama looked at him confused, and when he was about to speak, Hashirama made a hand motion, and quickly, several wooden hands emerged from the ground, managing to grab Panda, Maki, and Inumaki in time, pulling them away from the area and towards him.

Maki, who seemed about to protest, stopped immediately upon seeing the white hand emerge from behind the classroom's blackboard, pulling her spear, which had been left embedded in the blackboard.

The reason Yuta had such an oppressive presence became clear when

 a distorted voice screamed in anger. Tobirama looked at Hashirama in panic.

"Hashirama!" Tobirama exclaimed upon seeing the hand trying to grab them.

"I KNOW!" Hashirama responded with speed, clapping his palms together and creating a wooden dome to protect them from the impact. From the ground, two wooden pillars tried to contain the curse's hands that apparently protected Yuta.

"DON'T MISTREAT MY YUTA!" shouted the curse before Yuta, with much effort and a bit of love, tried to calm it down.

Gojo, who observed the situation, smiled calmly. 'So this is one of his behaviors, huh? You really have a powerful thing in terms of protection, don't you, Yuta?' Gojo thought.

Sometime later, after the curse had calmed down thanks to Yuta's significant effort and affection, the wooden dome opened, revealing a tense Tobirama ready to use Hiraishin anywhere in the school and a tense group as well.

With a smile, Hashirama looked at everyone. "That's why it's good to be kind to anyone," he said with a smile and a bead of sweat rolling down his face.
