-(My Hero Academia Earth)-
(3rd Person POV)
Rimuru stood atop one of the many buildings on the city rubbing the back of his head as he muttered to himself.
"Good God. I feel like Kyojuro did something really dumb and miss Onodera was present for it."
Rimuru shook his head to clear his thoughts as he scoured the city.
"Crime really is rarely happening at this period of time. Before the whole USJ Arc, everything looks pretty normal. Petty thieves aren't active, heroes roaming their streets looking for the next big villain to stop and get the spotlight to improve their hero rankings, and the big bad's haven't made their moves either."
Rimuru leapt from building to building, sometimes occasionally helping out some of the elderly to cross the streets or help carry their groceries, and at some point he even stopped by and helped out at a local soup kitchen which the volunteers were more than happy to accept.
"Rimuru-San. Could you help Hotaro-San, Miyazaki-San, Haruto-San and Misaka-San clean and prepare more food at the back kitchen? We've got quite a lot of people to feed at the moment."
Rimuru nodded his head as he replied.
"On it Tanaka-San."
Rimuru went to the back kitchen seeing the piles of rubbish stacked in the corner he briefly introduced himself to the volunteers who politely asked him to throw away the bags of rice, vegetables, bottled waters and other items littered all over the floor while they cut, rinsed, and cooked a fresh batch of food to give away.
Rimuru did as asked grabbing a large rubbish bag as he began collecting all the trash on the floor, and even projecting a broom and dustpan to sweep the floor much to the surprise of the volunteers who watched Rimuru clean the mess on the floor very quickly.
"All done! Anything else I can help with?"
Rimuru questioned as he tied another rubbish bag and yeeted it to a corner where a bunch of other rubbish bags were laid. One of the volunteers Misaka looked between the other volunteers before questioning.
"Can you cook?"
Rimuru nodded his head.
"As long as you aren't asking for a Michelin star meal I'm good."
Misaka nodded as she continued.
"We're making beef stew. Could we trouble you with helping the others to chop the vegetables?"
Rimuru saluted as he spoke.
"Let's do this!"
—(Scene Break!)—-
By the time Rimuru had finished helping out the Soup Kitchen, he realised it was already 6 pm, so Midoriya should already be at the beach. As he prepared to leave, he was thanked for his service by the volunteers and they even took pictures together before Rimuru vanished from their sights earning shocked gasps.
Rimuru leapt from rooftop to rooftop as he thought to himself.
'It shouldn't take too long to teach him the basics of the footwork, jabs, and crosses for him to start with. Then in a week we move on to hooks, and slips, then another week for uppercuts, feints, and counters.'
Soon enough, Rimuru arrived to the beach where he saw Toshinori and Midoriya present with Midoriya doing push up's on the sand. Toshinori was the first to take notice of his presence as he nodded in acknowledgment.
"Rimuru-Shounen. It's nice that you made it. Midoriya is already about to hit his limits for today, so I'm just having him finish off his training for today with some push ups."
Rimuru nodded as he replied.
"That's alright. Today I'll just be teaching him the basic footwork and how to throw a jab. 30 minutes to an hour is all he really needs."
Toshinori nodded at Rimuru's words as Midoriya fell atop the sand looking exhausted as Rimuru appeared before him and lifted the tire off the exhausted boy. Midoriya smiled weakly as he greeted Rimuru while taking his time to control his breathing.
"G-Good Evening Rimuru-San."
Rimuru playfully whacked Midoriya across his back causing the broccoli coloured hair boy to wince as he stretched out his hand to the tired boy and replied.
"Good evening to you too Midoriya-Kun! It's nice to see you grow so much stronger than when you first started. Now then, rest up for five minutes, hydrate yourself and get ready to begin you're boxing training! Today, we start at the fundamentals. You're footwork, stance and a basic jab."
Midoriya nodded enthusiastically as he tiredly accepted Rimuru's extended hand as Rimuru helped the boy to his feet.
"Thank you for the compliment! I'm glad to know all my hard work is paying off. And five minutes to rest and hydrate you say? Alright! I'm terrified yet also excited to be learning boxing from you! I hope you take care of me Rimuru-Sensei!"
Midoriya spoke tiredly as he headed to sit down where his watered bottle was as Toshinori approached Rimuru and spoke.
"The boy's confidence is much higher than when I first met him. Thank you for you're encouragement Rimuru-Shonen."
Rimuru nodded behind his mask as he answered.
"That's only because he's gotten comfortable around us. But it's a start."
Toshinori merely glanced at his protege as the timer for Midoriya's five minutes of rest rang out.
-(Scene Break!)-
Rimuru stood in front of Midoriya as he spoke.
"Before we begin. I need to ask, are you right or left handed?"
Midoriya raised his right arm.
"Orthodox huh? Alright, let's start with the basics. Since you're right handed, I want you're left foot forward."
"???"
Midoriya looked confused as he questioned.
"But…. I'm right handed…."
Rimuru nodded as he tapped Midoriya's left arm and explained.
"It's not to use to attack, but to gauge the distance between yourself and your opponent, keep them distracted, and used to send light jabs to keep your opponent's attention away from your dominant hand."
Rimuru then tapped the right arm of Midoriya as he continued.
"Now this bad boy here? It's your ace. It's the one you don't show too early. The one you strike with so that when it lands, it ends things. Let me give you a demonstration to get a better grasp."
Rimuru took a few steps away from Midoriya, getting into his own Orthodox stance. Guard raised to his cheeks, legs bent slightly, chin down eyes up as he spoke.
"You keep your strong hand in the back because it gives you distance. Time to build power. All the weight of your hips and back leg winds into that shot. It's like pulling back a slingshot—you don't fire from the front."
He shifted, throwing a slow jab with his left then a cross with his right into the air.
"Boom. That's why the right stays behind. It's the one they don't see coming. Your left talks. Your right answers."
Midoriya watched, absorbing it as he muttered.
"So being Orthodox means… leading with the hand that keeps them distracted?"
Rimuru waved his hand from side to side as he spoke.
"Not completely. This also applies to left handed individuals or Southpaw fighters. Whatever arm they are most dominant in, they use the non dominant arm to gauge distance between themselves and their opponents, and keeping their focus elsewhere."
Rimuru explained.
"Now come on! You just saw my stance correct? Mimick it, and I'll fix your stance for you."
Midoriya nodded enthusiastically. Getting into the same position Rimuru did earlier. Midoriya stood awkwardly, unsure of what to do with his limbs. Rimuru circled him slowly, eyes scanning.
"Left foot forward,"
He said.
Midoriya adjusted getting a nod from Rimuru.
"Good. Now bend your knees—just a little. You're not squatting, you're coiled. Like a spring."
He tapped the back of the boy's leg with his knuckle.
"Feel that? That tension's your engine. Keeps you ready to move."
Midoriya nodded, still stiff as Rimuru stepped closer, lifting Midoriya's hands gently.
"Raise your guard. Not too high. Keep your hands by your cheeks—not floating out like you're hailing a taxi."
He adjusted the Midoriya's elbows inward. "Tuck 'em in. Protect your ribs. Don't give me targets."
Then came the chin. Rimuru placed two fingers lightly under it, tilting it down.
"Chin down. Always. Think of it like putting your head behind a shield."
Midoriya did as asked and lowered his chin.
"Good. Now eyes up. You look at the chest, not the opponents hands. Hands lie—body doesn't."
Midoriya blinked, trying to process it all.
"Now hold it."
Rimuru said, stepping back to admire the stance.
"There. That's your foundation. Everything starts here. You mess this up, I don't care how fast or strong you are—you're just meat for the grinder."
Midoriya stood still, every joint tense with effort.
"Relax"
Rimuru said looking amused.
"You're not a statue. You're alive. So don't be too tense."
Then Rinuru stepped into the stance himself, mirroring Midoriya.
"Now, we learn how to move. Watch. When I move, I don't bounce. I walk."
He took a step forward—lead foot first, then the rear followed.
"Small steps. Stay in your stance. Always in position to punch or defend. Now you."
They started moving. Forward. Back. Left. Right. Every step was deliberate, quiet, controlled.
"Think of your feet like tracks."
Rimuru said.
"You stay on those tracks. Step off, and you're off balance. That's when you eat a punch."
Minutes passed. Sweat beaded on Midoriya's forehead. He was walking—but differently now. With focus. With tension in his legs, like a coiled spring.
"Alright."
Rimuru finally said.
"You're starting to get it. Now we learn how to throw hands."
He raised his left hand.
"A jab ain't just your arm. It's your whole body. From the ground up. Watch."
He demonstrated, slow at first. The weight shifted from the back foot to the front. His left foot pivoted just slightly. The twist started in the foot, rolled up through the thigh, the hip, the ribs, the shoulder—and then the arm shot out. A perfect jab, popping the air like a whipcrack.
"You feel that?"
he asked.
"It's a chain reaction. Feet to fist."
Midoriya nodded, eyes wide as Rimuru nudged him
"Try it."
He did. Slowly at first. Rimuru stepped behind him, guiding his elbow, touching his waist lightly to remind him where the motion started.
"Again."
Another jab. Better. More of his body in it.
"Again."
Another. This one snapped.
"There it is."
Rimuru said, nodding with a proud grin behind his mask.
"That's a real punch. You keep moving like that—grounded, tight, balanced—you don't need to be fast or strong. You just need to be efficient."
Midoriya lowered his arms, breathing hard. He wasn't just tired. He was learning a new language, one step and one strike at a time. Rimuru then clapped his hands once breaking Midoriya out of his trance as he spoke.
"That's all for today. Starting tomorrow for the next seven days we will focus solely on you're footwork and jabs before moving onto different techniques like cross, counter, slips and others like it alright? It's getting late already so get a move on kid."
Midoriya looked surprised until he grabbed his phone and realised it was already 7 pm.
"Ah! It's already so late! Rimuru-Sensei, All Might! I'll see you two tomorrow! And thank you for teaching me the basics of boxing today Rimuru-Sensei!"
And like that Midoriya bolted off the beach to head home leaving both Rimuru and Toshinori alone.
"You're a surprisingly good instructor Rimuru-Shonen."
Rimuru rubbed the back of his head sheepishly as he replied.
"You think so? I'm glad. Not everyday you get praise from the number 1 hero of Japan."
Rimuru playfully nudged Toshinori who just rolled his eyes before he turned serious.
"Rimuru-San…. Tell me, do you know where All For One is?"
The venom and malice spat out of Toshinori's throat at the mere mention of speaking the name of his arch nemesis and murderer of his mentor would have shocked anyone who would see the animosity brewing behind Toshinori's blue eyes. But Rimuru just shook his head as he calmly replied.
"Unfortunately not. But while we're on the topic of All For One, is there any updates about the upcoming plans on how to deal with the Nomu's?"
Rimuru's reply caused Toshinori to clench his fists as his knuckles turned white and he answered.
"No."
