[005] All About Secondary Traits

AFTER THE practical exam, Izuku excitedly went home. He didn't even come to All Might to report and instead, he eagerly shared his accomplishment with his mother.

Izuku wasn't happy about how he unknowingly did well in the practical exam and that all the teachers were eager to have him as one of their students nor was he excited about how he was able to break a giant villain robot with only a kick.

The reason for his excitement is how he realized after the practical exam that he was now able to use fifty percent of his quirk without receiving backlash from it. Maybe because of the adrenaline rush he felt when he saved that female examinee, he was able to release fifty percent of his quirk in that kick, which was such a great achievement.

It was not only his mother who was happy and proud of him but also All Might, who came at night to congratulate him in advance. Aside from congratulating him, All Might came to tell Izuku about his need to study how to control his dominant traits.

That's when Izuku remembered about the accident at the orientation hall. Izuku felt shy when his mother, Inko, stared at him in disbelief after All Might narrated what happened.

"And that's what happened, Mrs. Midoriya. Now I would like to borrow Young Midoriya again to have him study about how to control his secondary traits," Toshinori Yagi, All Might's real name, said.

Inko, Izuku's mother, knows about All Might's real figure when he wasn't using the remaining power of OFA but she didn't know about how Izuku's quirk was only inherited from All Might. So Inko also knows All Might's real name.

"But Mr. Yagi, Izuku just came from his years of training. How long will it take this time?" Inko worriedly asked.

"Don't worry, Mrs. Midoriya. It will only take three months at most. Honestly speaking, studying to control one's secondary trait, especially with how high quality Young Midoriya's dom trait is, three months isn't enough for him to master it. But with how great the teaching standard of I-Island is, three months is enough," Toshinori said assuringly.

"How about Izuku's result? I heard it will only take a month before it is distributed," Inko asked, looking worriedly at Izuku.

Before Toshinori could answer, Izuku patted his mother's shoulder. "Don't worry, mom. Whether I receive the letter personally or trust others to receive it, it won't change the fact that I will become a student of UA." 

And so with that, Inko agreed in the end. Since it was also for the well-being of Izuku, Inko had no choice but to agree, knowing that having no control over his secondary gender traits would negatively affect her son's career as a future hero.

Izuku only lived for two weeks since his return from his long training, when he once again returned to I-Island, this time not to train but to study about secondary gender and all about it.

"Midoriya, this is Haruki Abe. He will be your head teacher and coach for the whole three months you will be learning here. He's the one who will be responsible to you so whatever you need, just go to this person." 

Izuku stared at the person introduced by Dr. David Shield. This guy was no different than the people inside the I-Island.

Aside from his young and handsome features, he is a person who you will think of once you hear the word 'researcher'. A person with glasses and a lab coat.

"So you are Izuku Midoriya. Nice to meet you, young man. I am Haruki Abe, the head researcher on secondary gender traits, as well as a teacher inside the institute."

Haruki sensei introduced himself again with a hand outstretched for a handshake.

Extending his own hand, Izuku shakes hands with the other.

"Nice to meet you as well, Haruki sensei." 

"I will be leaving Midoriya to you, Abe. All Might will get him after three months. Make sure to teach him everything he must learn, okay?" Dr. Shield said to Haruki and the latter nodded with a smile.

"No need to worry, Dr. Shield. I will make sure he'll learn everything."

And after that, Izuku was once again passed to other people as Haruki introduced him to the other teachers that will be teaching him other aspects about secondary gender.

The next day after that was also the start of Izuku's private class. He was given a special classroom that only he owns in the I-Island Academy. He just finished his first lesson about the history of secondary gender acquisition and was given a fifteen-minute break before another assigned teacher for the next topic visited his study room.

His study room was half as big as a normal classroom, with complete facilities and materials. But instead of a normal classroom set-up of student and teacher's table and chair and a writing board, there was only one table and two chairs in the middle. As for a writing board, there was none.

If not for the manuscript books scattered on the table and on some cabinets, no one would think that this was a classroom.

Izuku, who did not leave the room, used the fifteen-minute break to once again read the notes that he had written.

Maybe because of his training with All Might, Izuku became used to writing notes rather than basing every knowledge on visual aids.

So all the details he had on his notes were from the key points that were stated by the teacher. And since it was only the basics, which were also taught since elementary school, most of the information he took down were those details he hadn't heard of or might have forgotten.

Now Izuku didn't only know what caused the manifestation of secondary genders and how it started.

With only his first one-hour class about the history of secondary gender, Izuku now knows the specifics of it, such as the person who leads the experiment about the low birth rate or the names of the volunteer couples who were the first to undergo the tests.

And it was only at this moment that Izuku heard about the titles "The Father of Human Evolution" and "The Carrier of the New Human", which were held by the people stated above.

Just how did the minds of those scientists think that they just needed to entitle anyone with anything?

Going back, Izuku was having the time of his life when the fifteen minute break ended. Soon, the next teacher knocked on the door before entering the room.

"Good morning, Izuku-kun," the newly entered person greeted.

"Ah, it's Melissa Senpai. Oh no, what I mean is, Melissa sensei," Izuku naturally teased the newcomer.

Melissa chuckled after closing the door. "If I don't know Izuku-kun, I would have thought that you're flirting with me."

"I am not!" Izuku widened his eyes as he waved his hands in denial and panic. "That was some pure and unadulterated comment. Please don't taint my words, Melissa senpai!"

His panicked and in denial stunt made Melissa laugh because she herself knew it well that Izuku really didn't mean anything at that and was just having his normal and casual friendly comments.

But she also knew just how Izuku would react when being teased and it was really adorable that she couldn't help it. That's why she always had that desire to tease the other first before she got to the serious part.

"Well, anyway. The break is over. Let's start with your first topic on this subject. Oh, wait. Do you already know what subject I will be teaching you, Izuku-kun?"

Izuku nodded his head. "Yes. Isn't it about the dynamics between a dom and sub? As for the specific topic, I don't have an idea."

"That's correct. Since it was obvious just how oblivious you are about the dom-sub dynamics, let's just start with the basics. And to start, I test you first if you are familiar with the terms in this dynamic. Is that right, Izuku-kun?"

"Sure. Ask away."

Melissa flashed a playful smile towards Izuku but the other was already busy on his notebook, jotting down words even though she hadn't started anything yet.

But she's already so used to this habit of Izuku that she can turn a blind eye to it. She just looked down at her own tablet to look at her prepared questions for this lesson.

"Here's the first question. An intense presence was felt in the area, forcing some subs to kneel and stay. What is it?"

Izuku didn't think twice and had an answer. "A glare."

"Correct. Can a sub defy a command given by a dom?"

"It depends?" Izuku quickly answered yet with a hint of hesitation. "Because of the power dynamic rule that was still applied. Like the command of the dom will only work as long as the dom is more powerful than a sub. Or if that sub was already claimed by the dom. Am I right?"

Melissa looked surprised at Izuku. "What? Did you have an advanced study?"

Izuku shook his head a little embarrassed. He didn't want to tell her about how he really did an advanced study after what occurred on the UA examination day. 

"Then let's see, hmm...how about let's put it in a situational question? Like Dom A was in a public place when he had undergone stress. Because Dom A is unpaired and there are already many subs that felt the dom's glare, what can we do to help?"

This time, Izuku wasn't able to create an answer. He put his hand to his chin as he tried to comprehend the correct answer.

"Wait. The question suddenly consisted of so many unfamiliar terms that I couldn't comprehend an answer. Can't we just help the poor guy back to the hospital before it could affect the subs and let the professionals do their job?"

Melissa took a few moments of silence before erupting a loud laugh. She even subconsciously got teary-eyed from laughing; she could only wipe it away before Izuku really ended up angry at her.

"I'm sorry for laughing. It's just that your answer is really funny yet very wise. If I were a different person who knows nothing about you, they might think that you're being sarcastically honest. It was so funny!"

Izuku can only allow the other and watch her laugh as she will. In his might, though, he was debating whether his answer was really funny or not.

"Okay, don't dwell on it any longer. I just really find your honest answer funny and nothing else. How about I just give you a post-test to see how far you did your advance study? Using this question and answer recitation was getting us nowhere."

And so Melissa handed out an exam paper out of nowhere. Izuku gladly accepted it and started answering while Melissa stared at his paper as he answered.

Because of this, when Izuku finds a question he can't understand, he will directly ask Melissa, who also answers him immediately.

And this was how Izuku had his three-month stay on the island to study everything about the secondary gender.

After celebrating a small graduation party with all his teachers as well as All Might and Dr. Shield, All Might brought him back to Japan the next day.

"Izuku! Welcome back!" Inko quickly gave her son a hug before greeting All Might as well. "Long time no see, Toshinori-san. Thank you for taking care of Izuku."

"Long time no see, Inko-san. I'm sorry for taking Izuku again for a long time. It'll be the last, I promise!" All Might even swears with his hand.

Inko chuckles. "It's fine, Toshinori-san. I know you just care for Izuku as your student and I am really thankful for that."

Toshinori quickly helped Inko to stand straight when the other tried to give him a bow.

"That's too much, Inko-san! It's also my responsibility as Young Midoriya's teacher."

To escape his current situation, All Might quickly transforms into his hero form.

"I will no longer take your time, Mrs. Midoriya. I'll see you at UA, Young Midoriya!"

Inko and Izuku watched All Might leave before they came back inside the house. The moment they entered, Inko couldn't help but hug Izuku again; this time was a lot tighter and longer.

"I missed you so much, sweetie. Although looking at you now, you don't seem like my sweetie before. Did you have a sudden growth spurt? You're a lot taller than me now. And you've got firm muscles. Oh my sweetie, can I still call you that?" Inko rumbles on and on while inspecting her son on her bosom.

"Ack! Mom! I will suffocate!" Izuku yelled.

Inko just laughed at her son and continued her antics.

Izuku could only allow his mother to know that the other just missed him. The mother-son pair continue their reunion at the dining while eating food that Inko prepared for Izuku's return.

After telling his mother about his own journey during his three months of study, he also asked her mother what the other did when he was away.

"Well, I didn't do anything aside from doing work though. Oh, wait. I actually did something different. Your Aunt Mitsuki visited a week after you left with Toshinori-san. She wanted to invite us to celebrate Katsuki's graduation. So I didn't go knowing that it would only be me who was an outsider at that. But a week after their celebration, they visited us to celebrate but then, they heard that you were still away so I didn't enjoy much."

Inko continues rumbling on while Izuku has his mouth wide open.

He had actually missed another chance encounter with Kacchan!

"Mom! Did Kacchan come as well? Did he say something? What did he say? Did he ask about me? Did he look for me?" Izuku bombarded his mother with questions.

And Inko was stunned at first. Then, as she watched Izuku continue mumbling, she couldn't help but chuckle.

"Look at you, getting excited just from hearing Katsuki. Relax, sweetie. He's not even here so there's no need to get nervous," Inko teased Izuku, who immediately got flustered.

"This version of you never changed, Izuku. You're still a sweetie when it comes to Katsuki-kun."

Izuku looked away, still with a blushing face. "Is it wrong, though, Mom? To feel like that towards Kacchan?"

"Of course not."

Izuku was slightly surprised with the quick denial of Inko. That made him hesitate a bit on his next words.

"But I am now a dom, Mom. When I am still a sub, acting and feeling that way toward Kacchan might be normal, but not as a dom."

Izuku's words silence both of them. Inko didn't speak because she didn't know what right words she must say at that moment. In the end, she could only release a deep sigh.

"What do we know about that, Izuku? We can't judge just because we find something out of the norm, right? It's your feelings and it is what makes you who you are and makes you happy. Just ignore others, whether it's the judging eyes of others or the instincts of our dynamics. If that makes you happy and accept who you are, then just do it, okay?"

That really succeeded in putting a smile on Izuku's handsome face. He didn't say anything and just smiled at his mother.

Then his face changed again and a pout plastered on his face.

"What is it again this time?" Inko worriedly asked.

"I still missed the chance of meeting Kacchan again. It's almost four years now since I last saw him. What does he look like now, Mom? He became more handsome, right?"

Inko chuckles. "Here I thought, you've become a proper dom now not only by looks. But the sub side of you quickly shows itself if it's about Katsuki."

Inko teased Izuku again but she still soothed his thirst for information about Katsuki by retelling how she had met the other when their family visited their new house.
