Vasectomy. A sterilization process for males which is done by cutting the vas deferens- the tube that carries the sperm from the testicles.
Once one undergoes such an operation, the male can continue to engage in sexual activities without the worry of leaving behind an offspring.
Normally, such an operation requires careful handling and a hefty sum. But with his Quirk, doing and undoing it only requires a single thought.
Hiro idly mused as he glanced at the naked Marika who had fallen unconscious beside him. Her brown hair was scattered all over the bed, and her sweat-soaked body exuded a tantalizingly sweet aroma that mixed with the cloying scent of her orgasm.
Feeling the urge rising within him again, he reactivated his Quirk, stopping further production of testosterones and at the same time limiting the production of his other hormones to a certain threshold.
Hiro inwardly moaned. Truly, the feeling of having absolute control over one's whole being was a pleasure many cannot fathom.
However, he was always careful to not lose himself to this sense of pleasure. Once he did, he'd become a logical monster whose only pursuit is his self-interest.
It was why he was always careful when modifying anything related to his brain; only enhancing his memory, senses, reflexes, and learning ability while avoiding as much of the limbic system which governed emotions.
He mainly gains control of his emotions by limiting the hormone production of the endocrine glands throughout his body at a certain level. This way, he'd still be able to feel the joys and sorrows of life while ensuring extreme emotions wouldn't affect his decision-making.
However, having read and watched many mangas and animes in his previous life, he knew that the common ending for characters that have their emotions suppressed is for it to implode in the worst possible timing one day.
Therefore, he needs a method to periodically let his emotions out.
At first, he thought of just letting his emotions run wild during battles. But that idea was quickly vetoed. While anger and adrenaline can marginally increase power, having impeded judgement as a drawback is not worth the tradeoff.
The next outlet he thought of was sex. And after trying it once, he immediately decided it'd be his permanent method of emotional release.
"Hnggh, Shiro-kun, did something good happen? You were much more enthusiastic than usual."
Marika's sleepy voice interrupted Hiro from his post-nut introspection. He turned to the buxom woman, his eyes briefly glancing down at her exposed breast before replying.
"Can't it be because I just missed the beautiful Miss Marika?"
"Hmph, glib tongue. Come on~ tell me the truth~"
Hiro chuckled at her playful antics, before loudly sighing.
"It's partially true. I wanted to make the best memories tonight. After today, we probably won't meet again."
"Ehh! Why!? What happened?"
"I got promoted at work. However, I need to move to their main headquarters tomorrow, and it's quite far- another country level of far."
"I-is that so…great! Congratulations! I'm happy for you."
Hiro inwardly sighed when he saw the forced smile on Marika's face. He was really a sinful man.
However, although he knew what she wanted him to say, a word of comfort or maybe reassurance that he would come back from time to time, Hiro didn't say anything.
When they first met a month ago, they agreed that their relationship was purely to satisfy each other's sexual needs. So before the relationship gets more messy, breaking up decisively was the correct decision.
The two of them slept in silence that night. After Marika woke up the next morning, the figure of Hiro was already no longer there.

The remaining two weeks of vacation quickly passed and it was now the beginning of the new school season.
During this period, Hiro mostly focused on Quirk training and accompanying the kids in the orphanage. Of course, he also went out a couple of times to 'vent' his emotions.
Dressed in the standard school uniform, Hiro once again stepped inside the gate of UA, this time not as an examinee, but as an official student.
"1A…I wonder who I replaced among the original cast."
Hiro thought as he familiarly walked across the campus ground. Having memorized the map beforehand, he didn't look like the new students who constantly kept looking around.
Maybe it was for this reason, that when he stepped into the main building, he was stopped by a freshman to ask for directions.
"Hello senpai! Excuse me, do you know where class 1A is?"
"1A? Follow me. I'm quite familiar with that room."
Mina Ashido, a youthful girl with pink skin and antennae on her head, had her black eyes widen in delight when the handsome white-haired senpai offered to accompany her.
UA is really Japan's No. 1 hero school. Just a random senior student she met was kind enough to personally guide her.
"Thank you, senpai! My name is Mina Ashido. Pleased to meet you."
"Likewise. I'm Ryugamine. Come, Ashido-san. I'm sure you're already very excited to meet your new classmates."
Mina raised an eyebrow. Ryugamine…why does that name sound so familiar?
Before she had time to think further, she saw Ryugamine's back already a few steps away. She dismissed her thought and hurriedly followed suit.
On the way, the two of them chatted nonstop. It was mostly Mina who excitedly discussed her feelings about being admitted to her dream school, with Hiro nodding along with a gentle smile, occasionally offering his insights.
Finally, after about 5 minutes, the two of them arrived in front of a large wooden door with a sign of 1A on top.
"Ah, are we already here? Thank you for leading the way, Ryugamine-senpai! Let's exchange numbers. I can't wait to tell you later about my first day in UA!"
"Is that so? Then Ashido-san, there's no need."
"E-eh? Ah haha, oh yeah. How stupid of me. Senpai must already be very familiar with what happens on the first day of school. T-then Ryugamine-senpai, I'll be going now."
Seeing the stiff smile on Ashido's face and the lost look in her eyes, Hiro knew it was time for the punchline. Thus, before she could push open the door, his hand reached out before hers.
"What I mean, Ashido-san, is that you don't need to tell me what happens later. Why? Because I'll be accompanying you."
With a whoosh, the door was pushed wide open, causing everyone to see a pink-skinned girl with a look of utter confusion on her face, and a white-haired boy snickering by the side.
