My System: An Evolved Computer I Made With My Unique Ability—

Kirisaki Sana had been a teacher in the United Superheroes Academy for quite some time now and for some odd reason, she harbored hatred towards the Midoriyama Duo. No one knows what happened back then but she never hid her animosity towards the couple. Whenever someone asks her about the past, she would always brush it off with silence, and if she chose to speak, she would just say some cold remark about the appearance of the person who asked. It was quite a waste, to be fair. After all, Kirisaki Sana is actually the most prepossessing teacher in the entire United Superheroes Academy.

Not only that, but she's also a very famous model in advertisements and fashion alike. But then again, the reason why she never got the popularity she deserved was because of her rude personality. Because of that, she could only work once with an employer before she loses all her patience and throws a tantrum. That's her usual way of dealing with disappointments and mistakes, and it had become her brand, as much as she hated to admit it.

Well, the reason why she was like that was because of her spoiled environment. Having been born from a rich family, she never lacked anything in her life, and now that she's got a superpower in her arsenal, she was basically on top of the world.

Nevertheless, Sai Tama saw something in her and decided to employ her as a teacher in the United Superheroes Academy. She may be the youngest teacher and the most problematic one, but Sai Tama saw her potential and patiently groomed her into becoming a teacher... well, it's working so far since  she's improved compared to before.

Two years ago, when Kirisaki Sana was employed as the biology teacher and the head of the nurse's office, she wouldn't miss a day complaining to the Principal about her day. It always happens after school, with no breaks whatsoever. Sai Tama, on the other hand, didn't see any harm in it though since she never caused any trouble. She could be so shameless in barging into the principal's office and complaining but she never talked back to any students she met. In fact, she had the farce of being an easygoing teacher even though she had an entirely opposite personality.

But then again, there were times when she ripped off that pretense and threw a tantrum in front of her students... but her students thought that maybe she just had a bad day. After all, losing patience happens to the best of teachers.

​ Today was a different case altogether, though, since Kirisaki Sana barged in on the principal's office even though school was not over yet. Sai Tama didn't say anything about it though, he just sat there with a calm expression while his arms are folded on top of each other, pinning the stack of paper on his desk since it might fly away if Kirisaki Sana started blasting with her temper tantrums.

"Kirisaki Sana, what seems to be the problem?"

"Sir, wh— why was that Satoshi kid chosen as one of the inter-high candidates? Didn't he cheat during that hero training?!" She exclaimed, her voice cracking. "Did you see what he did? He used his familiars. How could we know that those familiars are his? What if his parents bought it for him? Shouldn't we look more into this matter before we do anything else? If he was actually using familiars that he didn't get using his superpower, then that would damage the reputation of this school. Principal Sai Tama, what were you thinking? You shouldn't have overlooked such an obvious thing. This is why I told you to just expel that kid back then. The moment I laid my eyes on him I knew he was up to no good."

"That's a good point." Sai Tama mumbled, continuing on with his stack of paperwork. A smile formed on his lips as he realized that Kirisaki Sana was quite level-headed today. Was it because of her hatred towards Satoshi's parents? Or did she have an incredibly good day? Whichever the case, Sai Tama was relieved that he didn't have to clean up his office after Kirisaki Sana's visit. "But how could we prove that those are his familiars? Just like we can't prove they aren't his, we also can't prove that they're his. Besides, how could we expel him when he showed satisfactory results during that initial testing? And aren't we done about this matter? That girl he was fighting with surrendered first... I think her name was Shiroi... and because of that, he was able to advance. Also, what is up with your outfit? That is unbefitting our school's standards. I suggest you change your clothes first before we continue talking about this."

"Also— don't get me started on Satoshi. We both know why you hate the Midoriyamas. Don't bring something personal to school. If you want to complain about my decision about Satoshi, then should I tell him your secret?"

"B-but!" Kirisaki Sana wanted to complain more but it was obvious that she was already caught between a rock and a hard place. There was nothing left for her to say so she decided to keep quiet about it. Her sentiment remained the same, however, no matter what the principal told him. "I didn't have any teacher uniform left! They're all a size smaller now... did I get fat?" She continued. "Was it because I turned twenty this year?" She said to herself, pinching a little bit of fat on her waist.

"I'll send in a request about that. Expect new teacher uniforms tomorrow. Also... " A mischievous smile formed on the principal's lips as he grabbed the tickets from his desk. Once again, he started fanning himself with it. "You actually came at the right time. I got a few tickets to the nearby amusement park that recently opened. I was hoping you'd go there with a few students... you know, some sort of an excursion but with a small group."

"Really?! Yay! I haven't been to the amusement park in so long. Will I go with an entire class? Please don't give me Class 3-1, please." She pleaded, but her eyes were already sparkling with excitement.

"You'll be going with the inter-high candidates after class." The Principal almost let out his laughter after saying it. Fortunately, he maintained his composure and handed the tickets to Kirisaki Sana. "Oh, and also, don't even think about excluding Satoshi. Remember your secret which is safe with me." He indirectly threatened.
