My Stepsister in Kyoto

After dinner, Mizuto had always enjoyed his quiet time as he made money while checking his system. 

"Level 8, huh?" 

There was one extra skill point, and he put it into the "Sport Students" as he wished to max this skill as soon as possible. 

"What about after that?" 

After he maxed out the "Sports Students," he felt like adding skill points on either "Art Students" or "Humanities Students" so that way, he could learn art-related skills faster or learn a language.

"Maybe a language is better." 

He could only talk in three different languages: English, Japanese, and the language of the country where he had lived in his previous life. Yet, in this world, there were at least 7,000 languages, and while he didn't think he would learn all of those languages, he felt like learning all the most popular languages in the world. 

As for the "Arts Student" skill? While he might wish to learn an art-related skill, especially when he was interested in the concert band club, he wasn't sure whether he would join this club since he wanted to see the real situation of the club and there was still a time before he came to visit the club. 

Frankly, he felt his speed at raising his level was slow, and he wished to level up as soon as possible. There were countless jobs that he could choose from in the system, and their numbers reached hundreds of thousands, which was incredible. Still, even so, he didn't think that, with all of his life, he would be able to choose all of those jobs, so he knew that he could only choose the necessary ones. 

Nevertheless, watching the screen of his laptop and the amount of money that kept increasing, he felt like it was quite dull. It wasn't as fun as when he had an interaction with Akatsuki and Yume. Yet, he knew money was necessary, and he also wanted to make his life comfortable. 

With all the money he gained from the FX trade, he knew that he could buy an equity firm already, so he didn't hesitate and bought on from the "Store." 

Unlike in real life, where there were no complicated steps and even a human relationship, everything was instantly solved with the "Store." All he needed was money, and everything was solved. Moreover, there was no need to worry about their loyalty as they would be brainwashed to be loyal to him. 

Frankly, when he saw the effect of the "Brainwash" skill, it was frightening, and it was also why he didn't use this ability in real life since a fake relationship wasn't something that he wished to have. 

However, the strongest one had always been the loneliest. 

"So, this is the path of greatness." 

It was a lonely, thorny path, yet he wouldn't stop. 

Because of this, he took his smartphone and called the manager of his private equity firm, talking about the firm's current situation. 

"Irido-sama." 

It felt weird, but he knew that he needed to get used to this feeling. 

As they talked, the door of his room was knocked on, and Yume's head poked in from the gap of the door. 

"Mizuto?" 

However, she was startled when she saw him talking with someone on a call.

He also noticed Yume and made a gesture for her to be quiet. 

Hesitating, she decided to leave since she didn't want to bother him since she could see that he was working. 

"I-I will come back later." 

When he nodded, she closed the door and returned to her room before letting her body fall into her bed. The light was a bit dazzling, so she put her arm on the top of her eyes to cover its radiance. 

Meanwhile, his conversation with the manager of his firm ended as he thought about what he was going to do with his money. Frankly, he had a lot of money now, as his assets were about one billion yen, which was more or less about ten million dollars. This was a lot of numbers, and there was no doubt he could live a comfortable life with that money without working, but he felt that wasn't enough as he wished to get a real industry, something with a shape instead of just a number on the screen.

As he had gotten this system, it would be wasteful if he didn't make his life comfortable, but it also made him wonder what kind of business he should get first, and frankly, when he saw the price of many items sold on the "Store" skill, his asset was nothing. 

"Let's think about it later." 

He left his room and went to Yume's, knocking on her room door. 

"Huh?" 

Yume seemed to be startled when she saw him knocking on the door of her room. 

"We haven't done it in your room. How about we try it now?" 

"....." 

His light was so bright that it made her almost blind, yet Yume had to say he was warm.

"What are you writing?" 

The next morning, Yume stared at Mizuto, who seemed to be writing something on the paper as they walked to the school together. Like yesterday, he was still wearing a turtleneck undershirt since his stepsister never learned about self-control. 

However, Mizuto didn't answer Yume and focused on his calligraphy. 

While it was weird why he started to write calligraphy, Yume blushed when she read the words that came out from his brush. 

"Begin with discretion, end with abandon." 

Last night, Yume showed a wild abandon undetectable from her external primness and self-possession. 

"Stop writing something stupid!" Yume quickly stole his paper and scolded him in embarrassment. 

It was said that humans would show the opposite of their inner self. 

The good student appearance that Yume showed before was nothing but a facade of her lewd nature. 

"Next time, learn how about self-control, okay?" 

"I-I know." Yume folded his paper and decided to keep it as a collection where she usually kept all the remains and traces when they dated during middle school. "But... but you can wear that turtleneck, right?" 

"Then, do you want me to leave hickeys on your neck tonight?" 

"I am sorry." Yume apologized sincerely. 

Frankly, wearing this turtleneck undershirt was hot. 

The temperature of Kyoto wasn't like in the north. It was humid and hot. While the spring was quite cool, he needed to have some preparation for the summer as he was afraid that he might pass out due to the heatstroke. 

Still, as the two of them walked together, there was no doubt that their relationship became closer and closer. They might not define their relationship, but there was no doubt that it was impossible for them to describe themselves as stepsibling, especially with what they had done every night. 

Moreover, the two of them knew that as long as there was a chance, like what the calligraphy he had written before, they wouldn't hesitate to abandon themselves in improper indulgence.

Yet, the wronger it was, the more excited they were. 

It was as if this inappropriateness was a fuel that burnt their desire to be together even stronger. 

However, unlike her, who was single-mindedly thinking only about him, wishing to give her everything to him, he was different. 

"Good morning, Irido-kun~!" 

"Good morning." 

Greeting his classmates politely, a cheerful voice suddenly came from behind. 

"Good morning, Yume-chan~! Irido-kun~!" 

"Good morning, Akatsuki-san." 

"Good morning, Minami-san." 

Watching Akatsuki, who looked at him with a discreet, playful smile, Mizuto hoped that he never knew this pandora box.
