"WOW! BAKUGO CAN MAKE EXPLOSIONS!" A child in a Japanese kindergarten uniform said excitedly as Katsuki lets out another small explosion from his hand, as he saw Izuku smile, amazed by it, "WOW, KACCHAN! I hope I can get mine soon, too!" "...YEAH, AND YOU'LL BE MY SIDEKICK!" Katsuki froze with a guilty smile, he knew Izuku was going to be quirkless, which is why he'll help him until he gets OFA.
"Kid, you got carried away." Arthur said with a sigh, he couldn't blame Katsuki. He was still just a kid, who obviously wanted admiration. Luckily, he was able to prevent this kid from getting a big head.
*14 days later*
"He's quirkless?" "Sucks for him." "Too bad." Even the teacher looked at Izuku with pity.
"OI, THEN YOU'LL BE THE FIRST QUIRKLESS HERO!" Katsuki yelled, seeing Izuku hollowed and defeated expression as he looked up, Katsuki reaching his hand out with a wide cocky confident smile.
"R-really?"
"YEAH! Now come on! We got to train!"
The plan has begun! PLAN OVERPOWERED, LEAVE EVERYONE IN THE DUST! NUMBER ONE HERO AND TWO HERE THEY COME!
"K-Kacchan! I can't!" Izuku yelled exhausted, running around the playground for the 3th time as Katsuki ran beside him, "WANNA BE A HERO THEN RUN! ALL MIGHT WOULDNT GIVE UP!" All might was a cheat code to make Izuku more determined. Seriously, what a die hard fanboy.
*2 hours later*
"Kachan..ahh….do you do this everyday?" Izuku asked, lying on the ground exhausted as Katsuki sat beside him. Katsuki nodded softly, "Yeah. 10 push-ups, 10 laps, 10 jumping jacks and the rest everyday. I'm going to beat All Might!" It was the training plan made by Arthur, keeping in mind Katsuki's still developing body.
"No way!" Izuku retorted as Katsuki exploded, "HUH! ILL BEAT HIS AS-" He paused before starting again, "Yeah, okay."
"STOP THAT!" Katsuki echoed angrily in his mind, his furious expression confusing Izuku. Arthur continued to take over his body temporarily to stop his words and actions.
"Stop being a brat then and I won't need to take over."
Katsuki grumbled angrily as a small explosion released from his forearm, Arthur took over and began speaking, "We'll both have to train like hell. Tell your mom to put you in a martial arts lesson. Make her call my mom so I can join too by peer pressure. I'll also make a training plan for you. Don't slack off for even a second if you wanna compete with me." Arthur knew the gravity of the issue, Izuku didn't know the story and plot but he did. Katsuki knew some but was largely still in the dark. All for One and Shigaraki are apocalyptic characters, they were strong enough to destroy all of humanity. However, the most worrying part was the changes in the story. Katsuki originally should have only been able to use his hands but now, he could use it all over his body. Deviations caused by him. He had some theories but that was it.
"GOT IT?!" Katsuki suddenly erupted, Arthur giving control back, startling Izuku, "Y-Yeah!"
"Annoying bastard." Katsuki thought irritated at Arthur's actions. It wasn't a pleasant feeling knowing that he could be kicked out of his body at any moment. However, Katsuki was lucky. Arthur could have easily taken over his body completely, taken his identity and become Katsuki without any trouble. After all, a soul that was more defined and older like Arthur would win against Katsuki's new and developing soul. Katsuki stood no chance against Arthur.
"It's time to go home, kids!" A teacher said as Katsuki stood up, grabbing his stuff before leaving the school with Izuku. He turned, reaching the splitting path as he yelled, "REMEMBER TO TELL HER!"
"Got it, Kachan!" Izuku said, waving goodbye frantically. Katsuki lived in a residential neighborhood while Izuku lived in an apartment complex so they had to go opposite directions.
"Hey, kid! Be nice!" Arthur echoed in their brain as Katsuki exploded, "BE QUIET!"
"You're mad because Izuku surpasses you, loser."
"ILL KILL YOU!"
"L-la-loser!" Arthur mocked him, enjoying the emotional maturity of the little dynamite stick. Originally, they couldn't speak to each other, hell, they didn't even know the existence of the other soul. The older Katsuki got, the better the connection. It was like both souls were warping into each other and sooner than later, both would be indistinguishable to each other. A new entity.
"BRAT!" Mitsuki said angrily, greeting him at the door before pulling Katsuki's ear, "THE SCHOOL CALLED ME TELLING ME YOU WERE BULLYING IZUKU!"
"H-honey, let's calm down," The poor man said, facing the tyranny of his wife as he tried to save his son. "YOU'RE ON HIS SIDE!" Mitsuki yelled, glaring at Masaru. "N-no!" Defeated just like that.
"BULLYING! THAT WAS TRAINING! GET YOUR FACTS STRAIGHT OLD HAG!" Katsuki exploded back as Mitsuki picked him up. It wasn't much of a struggle to pick up a four year old. "Maybe some beating will teach you something." Mitsuki said as Katsuki yelled, "TRY ME!"
"H-honey! We can talk about this!" Masaru said, his hand shifting nervously. "BE QUIET UNLESS YOU WANNA BE NEXT!" Mitsuki yelled out angrily, making Masaru blush.
"What the fuck," Arhur echoed, noticing Masaru reaction.
"GET OFF OF ME!" Katsuki screeched as Mitsuki lowered his pants before smacking his buttocks. "ILL GET YOU BACK FOR THIS!"
"OH YEAH! LOOKS LIKE YOU HAVEN'T LEARNED YOU LESSON YET!"
"Old hag." Katsuki said, trying to look dignified sitting but his butt hurt like hell.
"Brat," Mitsuki responded sharply, her hand burned. Katsuki was smart, he could use his quirk all over his body.....including his butt....so he made an explosion to make her back off.
"You, two, calm down, it was a misunderstanding." Masaru said, trying to cut the intense atmosphere as Mitsuki added glaring at Katsuki, "I'll start making lunch."
"Honey!" Masaru added worriedly, before sighing at the exiting figure of Mitsuki. "Son, try to be nice with your mother." "No." A sigh left Masaru's lips as he muttered, "Uffh, just like her."
"How did you get with the old hag anyways!" Katsuki asked, he didn't really care, he just wanted to call her old hag again. "Ah, well, it was in a fashion modeling show. Around 10 years ago, while I was still an apprentice for my fashion designer company and your mother was a model, who was assigned to me and well....the rest was history." Masaru said, embarrassed, scratching his cheek. Katsuki wanted to jump off a cliff. For the first time, he didn't want these memories from Arthur. "But, your mother loves you very dearly....even if it doesn't look like it. So try to listen to her." Masaru continued as Katsuki nodded absentmindedly. Listen to her? Fat chance of that.
"KATSUKI!" Another scream could be heard, Mitsuki was yelling again as Masaru sighed. "WHAT'S THIS WITH MARTIAL ARTS AND YOUR FORCING IZUKU TO DO IT!"
"FORCED?! HE WANTS TO BE A HERO WITH ME SO I'M HELPING HIM, GET IT RIGHT OLD HAG!"
"M-mitsuki! Izuku seemed quite happ-" A small voice could be heard on the phone before Mitsuki exploded again, "DO YOU NEED A BEATING AGAIN!" "SCREW OFF OLD HAG!" "COME HERE!" "NO!" Mitsuki ran after Katsuki as he dodged her around the house as Masaru picked up the hanging phone, "Inko?"
"Ah, Masaru! I apologize I didn't know it would come to this?!"
"It's alright but what's this about martial arts?" Masaru asked as he saw Katsuki fly in the air, as soot and smoke fell onto Mitsuki's face, pissing her off even more. "Well, Izuku suddenly asked me to let him join this Karate class with Katsuki and that he was training to be the number second hero with him."
"NO KARATE! TAEKWONDO, BRAZILLIAN, JIU-JITSU, OR BOXING!" Katsuki yelled as he narrowly dodged Mitsuki sandal from hitting him. "Well, I'm sure you heard that." Masaru said, exasperated as Inko chuckled, "Then, I'll pick one of those for Izuku." "Okay, I'll make sure Katsuki enters as well so please tell me which one you choose."
"Yes, thank you...have fun with them and good luck." Inko teased as Masaru sighed, "Ah, thanks, goodbye." Masaru hung up the phone as he stared at the mother and son pair as he sighed, "You two…"
"GET BACK HERE!" Mitsuki yelled angrily as Katsuki yelled back, "SCREW OFF, OLD HAG!"
This was Bakugo's household daily routine.
