First Day of School

A/N- Thanks for the reviews, they were informative. A couple of notes, Krillin is both underpowered and overpowered by me here. Remember this is RR army arc Krillin, he isn't anywhere near as strong as he is in the 22nd WMAT. It does take both Goku and Krillin, and even Bulma after all, to defeat the pirate robot. Not sure how the pirate robot scales to UA robots. Plus I gave Krillin the Kamehameha wave which he didn't use until the match with Chiaotzu in the 22nd WMAT. Of course all in fun to have him have a more dynamic power set. Also for the interaction with Ochako, he notices her before he has a brief talk to her as the girl with gravity powers with brown hair earlier in the chapter, but I get where your coming from. Also thanks for catching the other world line.

The morning sun cast a warm glow over UA High School, heralding the start of a new academic year. Students from all walks of life converged on the bustling campus, each filled with a mix of excitement and nervousness. Among them was Krillin, the mysterious martial artist from another world, age 14, who had accepted the offer to become a student at UA.

Krillin found himself wearing the standard UA uniform, which felt foreign compared to his usual martial arts gi. His insecurities about fitting in were tempered by his determination to make the most of this opportunity.

As he made his way to the entrance of the school, Krillin couldn't help but notice the diverse group of students around him. There was a boy with wild, green hair and a girl with pink skin. Another student had a pair of wings sprouting from his back, while a girl with a frog-like appearance hopped by. The variety of quirks and appearances left Krillin feeling like he had stepped into a world of superheroes.

Inside the classroom designated as 1-A, the students were already taking their seats. The atmosphere buzzed with excitement as everyone chatted and introduced themselves to their new classmates.

Krillin entered the room and found an empty desk near the back. He took a deep breath, reminding himself to stay true to his martial arts discipline and remain humble despite his unique abilities.

As the students settled down, the homeroom teacher, Shota Aizawa, made his entrance. He exuded an air of stern authority, and his distinctive red goggles added to his enigmatic persona.

Aizawa cleared his throat, silencing the room. "Good morning, Class 1-A. I'm your homeroom teacher, Shota Aizawa. Starting today, you'll undergo rigorous training to become professional heroes."

The students listened attentively, a mix of determination and curiosity in their eyes.

Aizawa continued, "But before we begin, we have a new addition to our class. Krillin, would you please introduce yourself?"

Krillin stood up from his desk and faced his classmates. "I'm Krillin, and I'm a martial artist. I come from a really isolated island, and I'm here to learn how to be a hero in this one."

A murmur of intrigue swept through the classroom. It seemed that Krillin's introduction had piqued the curiosity of his fellow students.

A boy with spiky hair and a fiery disposition, Katsuki Bakugo, couldn't hold back his skepticism. "A martial artist? What's that got to do with being a hero?"

Krillin remained composed, unfazed by the challenging question. "Martial arts have taught me discipline, focus, and self-control. Those are qualities I think every hero should have."

The response seemed to satisfy some of his classmates, but it left others still skeptical. Krillin knew he had a long way to go to earn their trust.

As the day at UA High School progressed, Krillin found himself navigating through a series of tests and assessments designed to evaluate the students' abilities. The challenges were diverse, each one intended to gauge different aspects of their potential as future heroes.

**50-Meter Dash:**

Krillin approached the starting line for the 50-meter dash, the anticipation of the test coursing through his veins. The other students around him displayed an array of quirks – some could boost their speed with bursts of energy, others used telekinesis to propel themselves forward, and a few had physical enhancements that made them naturally agile.

The starting pistol fired, and the students shot forward with a burst of energy. Krillin's legs carried him with remarkable speed, his martial arts training allowing him to maintain precise control of his movements. As he crossed the finish line, he couldn't help but notice that he had finished near the top of the pack.

**Grip Strength:**

Next came the grip strength test. Krillin approached the device, a simple-looking contraption that measured the force of one's grip in kilograms. As he squeezed the grip with all his might, the device's needle surged, registering an impressive reading.

The students around him watched in awe as Krillin's grip strength far exceeded their expectations. One of his classmates, a boy with a quirky ability to extend his limbs, couldn't help but comment, "Man, that grip strength is no joke. You're really something, Krillin."

Krillin smiled humbly, appreciating the camaraderie that was starting to form among his classmates.

**Standing Long Jump:**

The standing long jump test required the students to use their quirks to clear a sandbox designed for the purpose. Krillin focused his energy and leaped, soaring through the air with grace. His landing was impressive, and the measurement of his jump left the onlookers in awe.

The girl with pink skin, Mina Ashido, approached him with enthusiasm. "Wow, Krillin! You're like a human springboard! That jump was incredible!"

Krillin chuckled and replied, "Thanks, Mina. I've had some practice."

**Repeated Side Steps:**

The repeated side steps test demanded agility and precision. The students moved between three lines by sidestepping from one to the other. Krillin's quick reflexes and precise control of his movements served him well, and he completed the task with ease.

**Ball Throw:**

The ball throw test was next, and it presented an interesting challenge. The students were required to throw a ball as far as they could using their quirks. Krillin observed as his classmates used a variety of techniques – some projected the ball with telekinesis, while others employed bursts of energy or physical strength.

Krillin took his turn with a determined expression. He gathered his energy and unleashed it with precision, adding an extra boost to the throw without incapacitating himself. The ball soared through the air, covering an impressive distance.

Izuku Midoriya, a student known for his analytical mind, had been observing Krillin's performance closely. He had initially attempted to use his quirk through his whole arm but had been quickly stopped by Shota Aizawa's Erasure Quirk. However, he had taken Shota's advice to heart and made adjustments, using his quirk more conservatively to enhance his throw without overexerting himself.

Krillin watched as Izuku's ball landed with a solid distance, impressed by the young hero-in-training's adaptability.

With the completion of the initial tests, the students moved on to the remaining challenges: a distance run, seated toe-touch, and sit-ups. Krillin tackled each task with determination, pushing himself to excel in every aspect of the assessment.

The day at UA was a whirlwind of physical challenges and camaraderie. Krillin's performance had earned him respect among his classmates, and he couldn't help but feel a sense of belonging among these aspiring heroes, each with their own unique quirks and abilities.

During lunchtime at UA High School, the bustling cafeteria was filled with students from Class 1-A, each seated at their respective tables. Krillin found himself sitting with a group of his new classmates, their conversations a medley of laughter, excitement, and curiosity.

One of the students, Tenya Iida, had a serious demeanor and a distinctive engine-like quirk in his calves. He spoke passionately about his aspiration to become a hero who upheld justice and order. Krillin listened intently, nodding in agreement.

"That's admirable, Iida," Krillin said. "I believe heroes should be a beacon of hope and righteousness."

Iida's eyes widened with appreciation. "You share our ideals, Krillin. That's a good start."

As Krillin continued to converse with his classmates, he couldn't help but be intrigued by the quirks they possessed. Ochako Uraraka, the girl with gravity-defying abilities, explained how her power allowed her to levitate objects with a touch. She had dreams of becoming a pro hero to support her family's construction business.

Krillin was genuinely fascinated by Ochako's quirk. "That's incredible! I've never seen anything like it. It must be so useful in hero work."

Ochako blushed and smiled. "It has its moments. But I'm still working on mastering it."

As the lunchtime conversations flowed, Krillin learned about the quirks of his other classmates. Eijiro Kirishima could harden his body into an impenetrable state, while Shoto Todoroki possessed both fire and ice powers. Momo Yaoyorozu could create objects from her body, and Tsuyu Asui had frog-like abilities, including a long, adhesive tongue.

Krillin marveled at the sheer diversity of their abilities. "You all have such unique quirks. It's amazing how each one of you brings something different to the table."

Kirishima, who had spiky red hair and an enthusiastic personality, grinned widely. "Yeah, that's what makes being a hero so exciting! We all have our strengths, and we learn from each other."

As the lunch period continued, Krillin couldn't help but feel a sense of camaraderie with his classmates. Their quirks may have been a mystery to him, but their shared dreams of becoming heroes bound them together.

Izuku Midoriya, the student who had carefully observed Krillin during the tests, joined their table. He explained his quirk, "One For All," which granted him immense strength, and shared his unwavering determination to be the greatest hero.

Krillin was impressed by Izuku's resolve. "You've got the heart of a hero, Midoriya. I can tell you're going to go far."

Izuku's eyes sparkled with gratitude. "Thank you, Krillin. It means a lot coming from you."

As the lunchtime conversations continued, Krillin realized that despite the differences in their backgrounds and quirks, they all shared a common goal – to make the world a better place as heroes. He felt a growing sense of belonging among these extraordinary individuals.

With each passing day at UA, Krillin would not only continue to develop his own abilities but also forge deep bonds with his classmates. They were a diverse group of aspiring heroes, each with their own quirks and aspirations, and Krillin was eager to learn from them and contribute to their shared journey toward becoming the heroes they all aspired to be.

The first day at UA was a whirlwind of experiences, and Krillin couldn't help but feel both overwhelmed and inspired by the potential he saw in his classmates. He knew that adapting to this world would be a challenge, but he was determined to embrace it fully and become the hero he aspired to be.

After the lunchtime conversations, the students of Class 1-A returned to their afternoon classes at UA High School. The day was far from over, and there was much to learn and experience.

In the afternoon, they had a session on quirk analysis and strategy. The classroom buzzed with excitement as students discussed their quirks and how they planned to use them in hero work.

Krillin, despite his lack of a traditional quirk, was eager to participate. He raised his hand, and Shota Aizawa, their homeroom teacher, acknowledged him.

"Krillin, you don't have a quirk like the others, but I'm sure you have unique skills and abilities. How do you plan to contribute to our class and hero work in general?" Aizawa asked.

Krillin stood up confidently. "I may not have a quirk, but I've trained in martial arts for years. I have excellent hand-to-hand combat skills, and I can use my energy to perform powerful attacks. I'll do my best to support my classmates in any way I can."

The class nodded in acknowledgment, and Aizawa gave a rare smile of approval. "That's the spirit, Krillin. Heroes come in all forms, and your martial arts expertise will undoubtedly be an asset."

The rest of the class was equally enthusiastic about sharing their quirks and strategies. They discussed ways to combine their abilities for maximum impact and brainstormed scenarios where teamwork and quick thinking would be essential.

As the day continued, they had practical exercises in the school's training grounds. The students were paired up to practice their quirks and develop combat strategies. Krillin partnered with Ochako Uraraka, the gravity-defying girl.

Ochako grinned at Krillin. "Let's see how your martial arts skills match up against my quirk!"

Krillin nodded and assumed a fighting stance. The training ground buzzed with activity as students demonstrated their quirks and practiced combat maneuvers. Krillin was impressed by the versatility of his classmates' abilities and their determination to improve.

As the sun began to dip below the horizon, signaling the end of their first day at UA, Krillin couldn't help but feel a sense of excitement and purpose. He was surrounded by a group of extraordinary individuals, each with their own unique quirks and aspirations. While he may not possess a traditional quirk, he was determined to prove that he had what it took to become a hero.
