A Bully's worst Nightmare

Upon returning home, Izuku was met with his mom's angry expression right at the door.

"Izuku!"

Confused, Izuku asked, "I'm not late, so why are you mad, Mom?"

His mom grabbed a paper from the kitchen table and handed it to him. After reading it, Izuku understood why his mom was upset, so he tried to defend himself, "Listen, Mom, I..."

"Izuku, you haven't been to school in 2 weeks!"

Izuku dropped his head apologetically and started playing with his fingers. He explained, "You know it's boring for me there, Mom. I'm smarter than all the other kids. (And I was in college in my last life; every test in elementary school is a big joke to me.)"

His mom looked at his sad face and knelt down, asking gently, "Izuku, tell me, honey, are the kids bullying you?"

Almost wanting to laugh at the thought, Izuku replied, "No, Mom, I just don't like staying there."

"Honey, you read what the paper says. No matter how excellent of a student you are, they will expel you if you keep skipping school. Don't you want to be a hero?"

As soon as his mom mentioned the word "hero," Izuku immediately looked up. He had promised Muramasa to become a hero, so he knew he had to do his best to achieve that, even if it meant spending most of his precious time with the other kids. "Fine, I'll go."

1 Year Later

School itself wasn't as bad as Izuku had imagined. He only had to spend a couple of hours there, and afterward, he'd head to the forest. Since the day he summoned Cu, Izuku had made contact with many other heroic spirits, including a great Saber who taught him swordsmanship. After a few months, he could be considered a master in the art of the sword. However, there were seven classes, so he began training in other combat forms as well, particularly Spears from Lancers and Rune Magic from Casters.

"Oi, Oi, Master, be precise with your lines. Rune Magic isn't a child's play," scolded his servant.

Exasperated, Izuku asked, "Why in the hell are you a Caster again?"

Amused, Cu replied, "Are you jealous of my amazing talents? The Hound of Ulster, Cu Chulainn, is a master of all arts of combat, including being a Lancer and a Caster!"

"I wish I had summoned Scáthach," Izuku sighed.

Cu retorted, "What? Are you nuts? She would have grilled you, even if she were inside your body! She would make you train like there's no tomorrow!"

Izuku conceded, "Well, maybe I'm lucky to have you! Anyway, I have to go, Cu."

Pleased with the praise, Cu said, "Of course, as expected of me!... Are you going to summon that Saber again?"

"No, no. Mom wants me to hang out with the brats from school, and I don't want to worry her," Izuku responded.

"Well, socializing is good for kids. Sucks to be you, Master. Adios," Cu said, and his presence faded away.

With a sigh, Izuku went to the kid's park in his neighborhood to meet with his "friends."

To Izuku, this was the worst part of school. All the kids in his school were just that – kids. They didn't talk about any topics that interested him, not even when they discussed heroes. He wished he could stay home and watch anime like he used to, but the anime in this world sucked! Izuku could watch the news and get more entertainment than this world's anime. (For heaven's sake, why didn't this world have ONE PIECE, JOJO, or HXH? What the heck?)

The news was far more interesting as it showed heroes and villains fighting, but there wasn't a schedule; it just happened.

Arriving at the kids' gathering, Izuku saw that one of them was bullying another kid, a certain blond-haired idiot he recognized from the anime.

The blondie and his friends were kicking the kid on the ground while the leader used his explosion Quirk to scare him.

"Ay, snot brain, stop it," Izuku called out.

The blondie glared at Izuku and said, "What did you say to me, Midoriya? Want me to burn you up too?"

Walking casually, Izuku looked at the kid on the ground and said, "Get up and go home. Also, fight them next time. If you can't beat them with your hands, throw a rock or something. Don't just take it." Then, he turned to Bakugou and stated, "Katsuki Bakugou, the big bad of this place, huh? Well, if you hurt a kid again, I'm going to beat you up. Clear?"

Bakugou, aka Blondie, got angry and tried to punch Izuku, but Izuku simply stopped the punch using his palm. Bakugou then activated his Quirk and attempted to burn Izuku, but it proved futile. Even with his hand burning, Izuku was unfazed. "This is all you've got? I thought you were going to burn me," he said, twisting Bakugou's hand until it hurt. "Aghh, let me go!"

Despite the pain, Bakugou kept trying to kick Izuku using the back of his feet. While he was no match, his tenacity was admirable. "With endurance and strength like yours, I'm quite shocked that you're a bully. Shouldn't you be aspiring to be a hero like All Might or something? Don't bully others, because a bully's worst nightmare is a bigger bully."

With that, Izuku kicked Bakugou to the ground and left.
