In.

Out.

Izuku sat in a criss-cross, inhaling and Exhaling, a cast covering his left arm and a brace wrapping around his torso. Two hours have passed since his dad left the apartment. In the meantime, Ito had attempted to teach him a form of breath called 'Full Focus'. In theory, you push your lungs to their carrying capacity with every breath. Though Izuku didn't see the point in this.

"Why are we doing this again?" Izuku asked while exhaling.

"Full focus breathing both increases focus and strength, it increases blood flow, speed, thinking and reaction speed, rate of hypertrophy, and control over your body," Ito responds. "If you want to be a hero, you got to learn it."

Izuku gave it another attempt, inhaling deeply, bringing his chest up, and exhaling.

"I feel nothing, this is literally just breathing." Izuku said.

"Izuku," Ito said, "When you use full focus breathing, you have to really feel it. You are treating it too trivially."

Hisashi suddenly walked through the door of the apartment. "Hey, Ito, did you teach him the breathing thing?"

Ito looked at Hisashi with the visage of annoyance. "It's quite difficult to teach Full focus breathing in the space of two hours, MIdoriya."

Hisashi started stroking his stubble in contemplation. "This is no good." Hisashi said. Hisashi started to walk towards Izuku, he knelt down and he started poking at Izuku's cast. "How about some motivation, If you learn how to properly use Full focus breathing, you will be out of these casts in around a week."

"What?" Izuku asked, "It can do that?"

"Sure," Hisashi says, "Guess you will never know unless you master it."

Izuku tried again, but as he was inhaling, he was interrupted.

"Now I see the issue," Hisashi said. " You are breathing from your chest, you are supposed to be breathing from the stomach..."

"Diaphragm," Ito interrupts

"Diaphragm," Hisashi continues, "Once you get accustomed to breathing like that, we can start training seriously."

Izuku thought about it for a bit. "Training? What about school?"

"I'm gonna put you into a new school, I don't like the way you get beat up. Besides, you will be taking a sabbatical from school while you recover." Hisashi replied.

Hearing this, Izuku realized the broken condition that he is in, and that someone he used to consider to be his friend had put him here.

Taking a deep breath, extending his stomach, and exhaling; Izuku tried to enter the state of Full focus.

One breath after another.

Everything started to slow down. Colours became more vibrant, sounds became louder and more crisp, he could feel the way the clothes brushed against his skin, the itch of the cast on his arm.

Hisashi took a look at his son: he looked like he was tweaked out. After watching Izuku stare at his hand for around five minutes, he shot a look at Ito, who nodded. Looking back at Izuku, a wide smile plastered across his face.

"You're Ready."

Izuku sat up in his bed, staring at the cast that covered his arm. "So you said that full focus breathing can heal my arm?" Izuku asked

"Technically, it would be mended faster, not healed." Ito said. "But you are nowhere near that level. The first thing you need to learn is how not to get overloaded with the amount of sensory input it gives you."

Hisashi was staring at his phone, looking up, he excused himself and went into another room.

Ito cleared his throat. "Do you have anything that keeps you calm? A mantra or a gimmick that you can use to keep from being overloaded?"

Izuku thought about this for a while before giving an answer. "I tend to count all of the lucas numbers, I find them relaxing."

Ito. thinking for a bit, his hands on his chin, pondered on this new information. "Try entering Full Focus, and trying listing out those numbers in your head."

Izuku did as instructed. As he started performing full focus breathing, the world began to slow 2, 1, 3, 4, 7, 11... The world began too slow, his senses were heightened, yet it was no longer like he was on some sort of drug. He felt the way that his blood pulsed through his veins and the seismic contractions of his arteries. However, this was not as attention consuming as before.

He looked over to Ito, a slight smirk was on his face. "Goood tthis is going better than expected." Ito said, at first, his words came out slowly, but then they seemed to return to normal speed. "Surprised that I am not speaking really slowly? You can kind of control your perception of time, you can slow it, but you can only speed it up back to normal."

Izuku looked mildly impressed with himself. "Now about this cast.

Hisashi was on the phone with his new employer. His excitement was barely containable. "So what you are saying is that I get to manage a bunch of carnies..."

"Mostly wrestlers," the man on the other end of the line said. "But yes, we do have other types of performers."

Hisashi grinned with excitement as he brought the phone closer to his ear. "I feel as though we are going to make EXCELLENT business partners!"

"Good," the man replied, "I want you here by eight a.m tomorrow."

This is going to be good. Hisashi thought to himself.

"...so remember, just keep the site of the broken bone well circulated." Ito said, "It should be mostly healed next week."

Izuku looked at his arm with fascination, "So what you are saying is that I not only need to be in full focus all the time, but that I also need to control the contraction of my arteries?" Izuku asked

"Yes." Ito replied

Thinking, Izuku came up with a plan. " I got it, so when I am in full focus, I can feel where the arteries are, so that should not be an issue, but instead of counting the Lucas numbers, I should count in hexadecimal instead, since it is in base 16, I can count to higher numbers with smaller ways of expressing them. This will allow me to stay within Full focus until I make it a habit. Thanks Ito!"

Ito was a bit baffled. I didn't say anything, darn this kid is quick A slight smirk came across Ito's face, You're gonna go far, kid.
