Riser and Ravel spent their entire day together, visiting various places, playing, and enjoying their time—neither thought of other things except for each other's presence.
Riser might not realize it, but because of his "Sex Mastery," almost all of his actions, temperaments, and talks, make Ravel unable to think of others other than her older brother.
He often teased her, joked, and made her laugh, making her show various emotions that she usually didn't show as she was a daughter of Lord Phenex, so she needed to act like a lady. Though, maybe, because he was her older brother, she could act like she wanted to do without acting.
Yet, at that time, he also observed the city where they lived and thought that this city was like a metropolis and it was full of everything. He was sure that that place would generate a large sum of tax, making the Phenex House even richer.
Nevertheless, he could tell that it was troublesome to manage this domain.
Fortunately, he wasn't the heir, he was just the third son of his father.
Moreover, his father was also the current master of the Phenex House.
When he thought about it, the life of Riser was perfect; the only unfortunate thing about him in the original was that his fiancee was taken by Oppai Dragon, Hyoudou Issei.
As for him, who had transmigrated into Riser, while he had to admit that Rias was beautiful, he didn't want a woman whose only advantage was only her breasts to become his wife. Moreover, he knew that this woman was a source of trouble, and if he married her, he might stay in Kuoh, which was the center of disaster in this story.
He, who had just become Riser, still wanted to enjoy his harem and lived in luxury by mooching his parents' money.
He didn't want to fight and just wanted to enjoy life.
As for the future of the Underworld, devils, and the rest?
It was better to leave all those problems to the main character since the role of the original Riser was nothing but just an antagonist in the beginning.
Still, the thing that he worried about the most was the system.
While the system gave him a good reward, the consequences were just so harsh that he might not be able to hold on.
He let out a helpless sigh as he watched the scenery from the hill.
It was almost night, and they thought of going back, but before they returned, Ravel told him that she wanted to visit the hill where she could overlook the entire city from a high position.
He agreed, and the two quickly came without any trouble.
In this domain, who dared to trouble them?
With how the society of the world of devils worked, even if he went to a random house to hold someone's wife, he would be okay.
Once again, being a Riser was good.
Still, before that...
"Thanks, Ravel."
"Ah?"
Ravel was surprised by her older brother's words. "Wh-What's wrong so suddenly?" Her face flushed red as if her secret had been found out.
"You asked me out because you were worried about me, right? Thank you, but I am okay."
He gently patted her head and thought that she was a wonderful little sister, so in Riser's place, he was going to take care of her.
[There is a hotel 100 meters away from your location]
"....." Riser.
While Riser was speechless, Ravel stared at her older brother with a blush. She knew that her older brother had changed. It was a change that she had never thought of, and this was why it made her curious and also worried at the same time.
Unlike her first and second brothers, Riser was quite unreliable.
Riser was, without a doubt, talented, but he acted like a bad boy, doing all the bad things, but no one said anything since he had the power to do so.
Ravel was also happy to follow her older brother since he cared for her well, and she also won the "Rating Game" with him, showing the prestige of the Phenex House.
Yet, everything changed after that engagement party.
His demeanor, action, and power were so much different.
Especially when he divorced Rias at that time.
While Ravel didn't say anything, her blood was boiling in excitement.
However, because of this, she thought that he was forcing himself.
Even the blind people could tell whether it was the Gremory or Sirzech who didn't want to marry him to Rias, so to protect the dignity of the Phenex house, he decided to make a drastic move by divorcing Rias even though he wanted her.
Frankly, this was the thought of everyone when they thought about his decision to divorce Rias.
Though his decision was manly and handsome, Ravel was worried that he had buried all negative feelings in his heart, and it was the reason why she decided to invite him out, yet she didn't expect that he would notice it immediately.
"Onii-sama..."
Ravel smiled sweetly as she hugged his arm tightly and leaned against his shoulder.
Riser didn't say anything, staring at the scenery of the town absentmindedly, but he thought that Ravel's growth was rather good since her breasts were huge, even if her height wasn't that tall.
'Is it a D cup? Or an E cup?
With his "High Intelligence," he used a complex mathematical formula to determine her size.
[There is a hotel 100 meters away from your location]
"....." Riser.
Though Riser didn't know, Ravel was staring at him, thinking that he was so handsome, especially when he appeared to be in deep thought. If she knew what he was thinking...
Nevertheless, similarly, her thoughts also returned to when she happened to see him together with all of his peerage members doing lewd and naughty. Even now, she could remember the euphoria on their faces, so she was curious... was it felt really good?
She looked at her older brother before she looked away with a blush.
'What am I thinking?!'
However, Riser didn't realize that and only wondered what he should do now.
The existence of the system might be strange, but he was okay with it since the system wasn't that troublesome except during the critical moment.
However, he was too free.
So, free that he wasn't sure what he should do.
Still, he thought that everything was so peaceful.
'How about I enjoy my harem again?'
When he went home, he was going to go all out with everyone, but—
[As a villain, how can you see your subjects live happily?]
[Be evil and exploit them!]
[Option 1: Kill your parents and become the head of the Phenex domain, then force your subjects to pay all of their incomes into tax. You will receive "Absolute Ruler"]
[Option 2: Force all of your subjects into the military and fight a war with the Fallen Angel, Heavens, and all the Patheons in the world. You will receive "Absolute Order"]
[Option 3: Create a business and use the people in your domain. You will receive "Mathematic Mastery"]
[If you don't do it, you will lose your left nipple]
"..."
Riser took back his previous words and thought that the system was simply too troublesome for him to handle.
