USJ, Roronoa Zoro

Zoro had just rescued the two students and taken down several villains. As he navigated the area, seeking a new spot to rest, he suddenly sensed an unusually strong presence. His instincts as a fighter immediately put him on alert.

Approaching the facility's entrance, he spotted a massive black entity lunging at a student who had previously attacked him. It was evident that the student was in grave danger. In a moment of determination fueled by Zoro's inherent protective instinct, he made the decision to intervene.

He intercepted the creature's forceful strike with his sword, impressed by the strength behind the attack. "Your strength surpasses the others," Zoro remarked, a sense of inner exhilaration rising within him at the prospect of an impending fight. A contented grin crossed his face because for Zoro, an intense battle was a form of joy.

With a deft movement of his wrist, Zoro hurled the creature several meters back, providing a momentary respite for the imperiled student. "You have courage, kid. Keep it," commented Zoro on the student's bravery before instructing him to depart, ensuring his safety. Without hesitation, the young student seized the opportunity and fled the danger zone with his friends.

The creature, known as Nomu, attacked Zoro as soon as it regained consciousness. Skillfully evading a powerful blow, Zoro severed Nomu's arm. He watched in surprise as the severed limb regenerated. This extraordinary ability piqued his curiosity.

From a distance, a man in peculiar attire jeered, "Hahaha, you can never defeat my Nomu! It was created to take down All Might." Zoro disregarded the man, staying focused on the ongoing battle.

Nomu attacked again, but Zoro skillfully dodged the strikes, eventually severing Nomu's extremities to reduce the threat. "I'm tired of playing with you," declared Zoro, assuming an offensive stance. With a controlled grip on his sword, he activated his technique: "Ittoruyo IaI… Shishi Sonson!" He executed a powerful attack, taunting, "Try to recover from that." Nomu was now divided into two parts, completely still.

Zoro observed Nomu closely, but as it remained motionless, he pressed forward, his focus directed toward potential further threats.


USJ, Izuku Midoriya

Izuku watched with rapt attention the seemingly brief exchange between the green-haired man and the mysterious creature called Nomu. It was less an intense battle and more a short but nonetheless impressive clash of martial arts and superhuman abilities. The precision of the green-haired man's movements fascinated Izuku, who tried to capture every motion in detail, hoping to learn from them.

Amidst the action, he caught the faint murmur of his class teacher Aizawa: "So, that's the Villain Slayer." These words jolted Izuku like an icy bolt. The Villain Slayer? Here, at the USJ? His heart began to race, a shiver running down his spine. He had heard of this dreaded villain, a legend among criminals. The Villain Slayer was renowned for his remarkable swordsmanship skills and primarily targeting villains. Occasionally attacking heroes, he had never made them his primary targets.

Recalling the stories circulating about the Villain Slayer, Izuku shuddered. He was notorious for shaking up the world of villains, often interfering in altercations involving the most unsuspecting heroes. It was terrifying to hear this dreaded name in a place like the USJ, a location usually considered a safe training ground for young aspiring heroes.

Despite the terror, Izuku felt a mixture of fascination and horror in the face of the situation. He wasn't sure what this unexpected presence of the Villain Slayer at the USJ could mean. It was as if a sword of Damocles hovered over the students' heads, spreading uncertainty and fear.

The way the green-haired man held his ground made Izuku suspect that this fight might only be the tip of the iceberg. Why would the Villain Slayer be here? Why attack the USJ? These questions swirled in Izuku's mind as he tried to process the events and comprehend what would happen next.

Despite the unexpected appearance of the Villain Slayer and the battle before them, Izuku felt a rising determination within him. He was resolute in using his abilities to defend himself and his classmates, even if it meant facing such a feared adversary.


USJ, Roronoa Zoro

After Zoro ensured that the creature known as Nomu was dead, he turned to face the two figures - one resembling a Logia based on his observations and a blue-haired man with a fetish for hands. The blue-haired man appeared agitated, constantly complaining about cheating. As a pirate, he didn't play by the rules.

Approaching Zoro, the two attempted to launch an attack. The blue-haired man tried to grab him, but his Haki warned of an unpleasant grip. With a swift move to the left, he evaded the grab and delivered a blow to the attacker's ribs. A satisfying crack resonated. These two undoubtedly had something to say. So, he decided to further provoke them to gather more information.

As he dodged the Logia's attack, Zoro took out his sword and slashed its cheek, causing a trickle of blood. The Logia appeared shocked, as if it had never heard of Haki and relied solely on its immaterial nature.

The blue-haired man attacked again. Tired of these pointless attacks, Zoro swiftly swung his sword, slicing through the man's thumb and index finger, causing a deep wound on his face. He screamed in agony as his friend pulled him away.

"Tomura Shigaraki, we should disappear. He has destroyed our Nomu and is taking a toll on us. This is a fight we cannot win," said the Logia. "You'll pay for this," whimpered the blue-haired man. A mist formed around them, and they vanished.

Zoro decided to help the children and carried the unconscious students back to their friends. None dared to approach him, and they all stared at him wide-eyed. The remaining villains acknowledged their hopeless situation and surrendered to his will.

Amidst the chaos and confusion of the battle, a girl with black hair and scanty clothing appeared. She seemed to have the situation under control, creating ropes from her body and beginning to tie up the captured villains. With skillful movements, she bound them to stakes, trees, and nearby objects. The villains cooperated and made no attempts to struggle against the restraints.

Gently placing the unconscious students with their friends, Zoro quickly checked their conditions to ensure they hadn't suffered any serious injuries. Seeing that they were safe, he turned to the girl.

"Thank you for your help," Zoro said, acknowledging the girl. She responded with a nod and a faint smile. Despite the devastation around her, she exuded an unusual calmness and determination.

The students were relieved to see Zoro helping them and seeming to have the situation under control. Some began to recover and gather themselves, while others tended to their injured friends. There was still unrest, but Zoro's presence had brought a certain calmness and reassurance.

The girl, revealed as Momo Yaoyorozu, quickly explained that she was a student from UA High School and had the ability to create various objects from her body. She had created the ropes to restrain the villains and prevent their escape.

Zoro nodded in approval and said, "You're brave kids. But it would be better if you leave this place as soon as possible. It's not safe here."

"Huh, what kind of extra are you, thinking you're so brave and strong? I'm stronger than you, I will defeat you and earn recognition for it." Some students reacted to the challenge from the spiky-haired boy.

Interrupting him, Zoro simply replied, "Defeat me? Don't make me laugh, you couldn't even dispel my boredom." This seemed to anger the spiky-haired boy, and he attacked loudly proclaiming, "Don't underestimate me!" Zoro barely took him seriously. He gave him a tap on the back of his head, immediately rendering the boy unconscious.

The girl named Momo Yaoyorozu apologized for her classmate's behavior. "We're sorry, Katsuki Bakugo has a serious anger problem." "It's all right, he's a frog in the well, clueless about how big the world is," Zoro replied calmly.

Katsuki Bakugo slowly regained his composure, but under Zoro's vigilant gaze, he realized it was futile to continue fighting against him. He lowered his gaze and fell silent.

Momo Yaoyorozu felt compelled to explain the situation: "I'm sorry, he's not usually like this. But his Quirk sometimes makes him impulsive."

Zoro looked calmly at Bakugo and said, "You should learn to control your impulses. It'll only lead you to ruin if you don't pay attention."

The other students respected Zoro's presence and how effortlessly he brought the situation under control. They prepared to move when suddenly, a distant rumble was heard.


USJ, Teacher of UA

The group of teachers entered through the large entrance gate of the USJ after Tenya Iida informed them about the attack. They immediately headed towards the site of the incident. As they crossed the main gate, they were greeted by a shocking sight. The ground was stained with blood, and body parts were scattered around—an eerie sight that left the teachers in shock.

In the distance, they spotted a group of students attending to some injured individuals. Some villains were tied up and under the control of the students. The extent of the destruction and injuries caused concern and dismay among the teachers. They rushed to the students to ensure everyone's safety and offer assistance.

The teachers were dismayed by the chaos they encountered. All Might Sensei, one of the first to arrive, began to assess the situation and calm the students. He praised their bravery and courage in maintaining composure and acting effectively in such a situation.

"Good job, kids," All Might spoke calmly. "You've handled this crisis very well."

Midnight, another teacher, took charge of treating the injured. She immediately started providing first aid to help alleviate the pain of the wounded. The other teachers worked hand in hand to stabilize the situation and minimize the danger.

Meanwhile, the arriving teachers were observed by the students with a sense of relief. They felt safer seeing their teachers around, knowing they were now in good hands.

"What happened?" Endeavor, one of the teachers, asked with a serious expression as he approached the group of students.

Yaoyorozu took the lead and quickly explained the situation: "A villain attack, Sensei. We did our best to defend the school and contain the threat."

The teachers gathered the information and began taking measures to handle the situation. They ordered the villains to be apprehended and attended to the wounded before further assistance arrived.

Amidst the chaos and devastation, the strength of the students and their ability to act under pressure shone through. The teachers worked hard to restore calm and secure the school while providing comfort and support to the students.

There was no sign of a particular swordsman.


I wanted to note that in this fic, there won't be any balanced fights on Zoro's part; by MHA standards, Zoro is too OP. I will make it his greater challenge to return home. This chapter should conclude the prologue, and I'll try to write smaller original arcs that run parallel to the original story. I apologize if the fights are written somewhat unspectacularly; I'm not too skilled in that aspect.

Regarding the question of why Zoro is so brutal, Zoro is a brutal character. One Piece is a Shonen, and thus, such things are not openly depicted, but I like it when characters like Luffy or Zoro are shown to be completely badass. The next chapter might take some time.
