Sakurasou is very peaceful today 3

As the morning came, Shishio brought Shiina back to her room silently, as usual, kissing her lips before he went to work out. Even though it wouldn't affect him whether he was working out or not, he wanted to exercise his mind so he wouldn't be lazy.

Sometimes, human's mind was working mysteriously, sometimes they were lazy, and sometimes they were full of energy, and Shishio wanted to exercise his mind so even though he was lazy, he wouldn't postpone or stop what he was going to do.

In other words, Shishio wanted to exercise his willpower.

With his body, if he wanted to get stronger, it was impossible to work out in a normal way, and the best way to get stronger was to fight someone, which was why tonight, he had decided to visit Tokugawa's house, and he was going to do it secretly.

After receiving a lot of abilities, even though Shishio had mastered their abilities instantly and remembered all of them in his mind and body, he still needed to use them on his body. After all, there were so many techniques, especially both "Bajiquan Mastery" and "Ninjutsu Mastery."

Shishio had to admit that both Bajiquan and Ninjutsu were his favorite abilities out of all the things he had gotten. After all, with both of those abilities, he could hide his presence.

There was no need to explain "Ninjutsu Mastery" since he had become a ninja by mastering this ability. Like a ninja, it was natural for him to know how to conceal his presence, but Bajiquan was different since it gave him the ability to manipulate "Qi."

"Qi' is a concept from the Chinese, and it is known as life energy. Still, until now, it can't be proved scientifically, and most people think of it as a mere myth, but after he received "Bajiquan Mastery," he slowly learned about the existence of "Qi" inside his body.

By manipulating "Qi," Shishio could perceive the exact conditions of the immediate environment and make use of the resulting perception to adjust and minimize the noticeability and impact of his existence.

In other words, as long as Shishio didn't want to, no one could find him!

Shishio was simply the strongest assassin in the world!

"Qi" manipulation might seem to be magic, but it wasn't the case since the human body was full of mystery, and until now, even though science had progressed so much, there were a lot of things that couldn't be explained by science.

If Shishio had to give an example, then it was a plane.

We were often told that the reason why a plane could fly was because of Bernoulli's principle, but the truth was no one really could explain why a plane could fly.

It was the same as "Qi," even though no one could see it and no one could feel it, it didn't mean that it didn't exist.

His meeting with Sakurajima Mai yesterday might be one of the triggers that Shishio decided to develop his "Qi" more.

Sakurajima Mai went unnoticed, and no one could see her, but if she said that to someone, would anyone believe her?

No.

Shishio was sure that most people would think that Mai was crazy and thought she might need to rest, thinking that it might be because of a physiological problem. Still, he knew that her problem really existed, and she became unnoticed by people.

The thought of being unnoticed and ignored, Shishio was sure that Mai was so frightened at that time, so it might also be why she didn't care much and decided to dress as a bunny girl in the original story.

As for the MC of the bunny girl, Shishio thought that Sakuta had the most common ability of the harem protagonist, and that ability was known as a lucky accident.

Someone might notice them, but the reason why the common harem protagonist whose face was normal and a loner could have such a beautiful girlfriend was that they just happened to be there when the heroines were in trouble.

Shishio was also the same. He just happened to be in Enoshima when Mai noticed that she had become unnoticed by people.

Shishio thought of how to save Mai except for confessing her in front of the crowd in the school, and he knew that there were many ways. The first one was to make her return to the showbiz industry, and he thought that it was the best way, considering he knew how she felt regret about her hiatus.

However, considering Mai's strong personality and independence, Shishio knew that his help might not be accepted. All he could do was wait for her, then told his conjecture at why she had disappeared.

It was impossible for Shishio to confess to Sakurajima Mai in front of the crowd, so he could only use the other method that he had thought of, and he needed someone's help for this method so after he greeted some beautiful housewives along the way, he returned to Sakurasou and took a bath before he went to Ryuunosuke's room.

*Knock!* *Knock!*

"Ryuunosuke, I need your help."

Shishio didn't knock on the door again and waited for a while before a creaking sound was heard, and the door was opened slowly. From the door opening, Ryuunosuke's head showed a listless and impatient expression on his face.

"What?"

"I have an interesting plan. Let's talk," Shishio said. Still, he was glad that Ryuunosuke didn't seem to know what he was doing with Shiina last night.

Hearing Shishio's words, Ryuunosuke's eyes, who was still sleepy, opened up as he gazed into him. He looked at him for a moment and nodded. "Good." He opened the door, and Shishio entered his room, and the two of them started to talk about their plan.

---

In the kitchen, Shishio was cooking breakfast, and since he knew that tomorrow, he could implement his plan, which put him in a good mood.

"Good morning, Shishio-sama."

Hearing this voice, Shishio turned his head and smiled gently. "Good morning, Roberta."

"........"

Roberta's face flushed as she gazed into his smile, and she was unable to wake up. She didn't know why, but she felt like the world was so beautiful and happy when she saw this smile. She also forgot all the bloody and tragic life before she met him, which made her want to see him show her this smile forever.

Watching Roberta, who was in a daze, Shishio's lips were twitching and asked, "Roberta, can I ask you something?" He thought that he should refrain from smiling since he felt that his charm was too dangerous. He was afraid that he might destroy a perfect family around this neighborhood since he seduced the mother or the wife because of his smile.

"Yes, Shishio-sama." Roberta moved closer, or rather she wanted to be close with him.

"Can you buy me this..." Shishio took the list of the things that he wanted to buy and gave them to Roberta.

Roberta looked at the list and couldn't help but raise her eyebrows, especially when she saw the soundproof compartment written on the list. She wasn't blind, or rather, she had noticed how Shiina didn't return to her room and went to sleep in Shishio's room. She also noticed how tired Shiina was after Shiina returned to Sakurasou on Sunday at that time.

When Roberta connected everything, she knew that both Shishio and Shiina had that kind of relationship, but the feeling that she felt at this moment was jealousy. However, she knew her position, and just by his side, she was happy.

"Yes, I'll prepare all of them when you return," Roberta said.

"Thank you, Roberta," Shishio said with a smile.

".........."

Looking at this smile, Roberta wondered whether it was wrong for a master and a maid to be together?

Shishio really wanted to get the soundproof compartment as soon as possible. Still, when he thought about the condition of Sakurasou clearly, he felt that it should be saved for him to do that with Shiina in this place, considering there was only him and Ryuunosuke on the second floor.

Shiro-san lived on the first floor, and Sorata and Mitaka had moved from Sakurasou, so as long as Shiina could keep her voice low, it should be alright, right?

However, when Shishio thought about his technique and ability, it was impossible not to make Shiina not moan so loudly. It was impossible to tell her to keep quiet so all he could do was to shut her mouth by kissing her at that time, but it wasn't effective which was why he needed the soundproof compartment.

But at the same time, Roberta wanted to remind Shishio. "Shishio-sama, can I give you some advice?"

"What's wrong, Roberta?" Shishio asked.

"I think you should refrain from smiling from now on," Roberta said.

"..........." Shishio.

Looking at the stunned Shishio, Roberta quickly explained. "I think that you should only smile at the people that you know, and if you smile so carelessly, you might get unwanted trouble." She knew how big Shishio's charm was, especially when he smiled. She had seen many crimes in this country, especially those committed by women. She didn't want Shishio to be followed by a stalker or raped by someone, so she thought it was better not to smile unless in front of the people he knew.

Hearing her concern, Shishio smiled and nodded. "Thank you for your concern, Roberta. I'm glad to have you beside me." That was the truth since he was glad to have Roberta beside him since she could help him with many things. There were many things around him that he couldn't explain to the people around him, so having someone he could trust to help him manage those things was a great thing.

"No, no, I'm just glad that I can stay beside you, Shishio-sama," Roberta quickly said as she blushed.

Shishio looked at Roberta for a moment and said, "Roberta, to show my gratitude toward you, I'll give you a reward."

"Re - Reward?" Roberta was surprised.

Shishio nodded and said, "You can ask me anything. As long as it is within my power and it doesn't cross my morals, then I'll give that reward to you."

"A - Anything...?" Roberta asked quietly and started to imagine a lot of things.

"Yes." Shishio then moved closer and whispered. "For example, I can be your butler and serve you for a day."

"...."

Roberta felt that her head was almost blowing up as her heartbeat raced at that moment. "I... I..." She stuttered and blushed, which made her look quite cute since the gap between the cold-blooded soldier and this blushing maid was huge.

"Well, you don't need to be in a hurry. You can think about it slowly, alright?" Shishio said with a smile.

"Yes!" Roberta said without hesitation, wondering what kind of reward she should ask for, but before that, she needed to finish the task that he gave. 'Soundproofing compartment...' She thought that she should ask someone to put them in Shishio's room as soon as possible and if possible, she should also put them in the other room beside his room, that way, there were a lot of things that she could do.

As Shishio continued to cook, the tenants of Sakuraou came up one after another while greeting him with a smile.

Shishio thought that this peaceful morning wasn't bad as he greeted them back. "Good morning."
