It was quite easy for a devil to go to the human world.
If they wanted to go, then they could apply right away, and no one would stop them.
However, there weren't many devils who wished to go to the human world even though it was easier to live there.
Why?
It was because staying in the human world wasn't that comfortable.
Unlike the Underworld, which was comfortable, many things in the human world made the life of the devil quite uncomfortable.
If he made an example, it was like a church, sun, temple, and all the holy related- things.
Moreover, it was also dangerous, especially when they might be hunted by exorcists, other supernatural beings, and many other things.
The high-class devils and those strong aside, those low-class and weak devils would have a hard time living in the human world.
Those difficulties made the devil wish to stay in the Underworld more than the human world.
If he gave an example, it was like how someone felt comfortable staying in their hometown instead of an unfamiliar city.
—or like a fish who loved to stay in the water instead of land.
Still, if the devils wanted to go to the human world, there were many ways, but this time, Riser went to the human world with the flying train, which was usually used by the noble who transported from one domain to another.
Still, Riser had to say that even if he had gotten used to transport by using this flying train, there had always been a novel thing every day.
"Riser, is there a place that you want to visit? I will guide you there."
"....."
Riser looked at Rias helplessly, who tried hard to make him happy.
Was this a licking dog?
Riser felt that this experience was quite novel, especially since it was Rias who licked him desperately.
Nevertheless, the others didn't think too much and only thought that Rias was kind and gentle.
Yet, this was Rias's advantage.
Her beautiful appearance, even if she had become a licking dog, those who were being licked would happily let themselves be licked by Rias.
Frankly, he didn't mind being licked either, especially when they spent quite a while together. Even though their interaction was quite minimal due to Serafall, Sona, and the others, they still talked.
Naturally, their interaction was so different from before when they were still engaged with each other; when they talked, Rias was quite chummy, kind, and even flirty. There was no doubt that, as a devil, her skill at seduction was at max.
Nevertheless, facing such a seduction, he was still as polite as ever. Facing her seduction, he could calmly face all of that like an adult, and it was also due to this that Serafall and Sona felt relieved and let him talk with Rias since they knew nothing would happen.
Maybe this was also the reason why Serafall didn't join them to visit the human world. After all, if she really wanted to go to the human world, would someone be able to stop her?
Still, the problem was Rias.
If he really wanted to take her down, then it was possible, but frankly, he didn't have such an intention, at least for now, especially when having a relationship with her would put him in a passive position against Sirzech.
Riser knew there was no way for Sirzech not to know and was blind that his sister visited his villa during a weekend, yet Sirzech still let Rias visit him. Why? Wasn't it because Sirzech wanted to see his little sister seduce him?
In the original, Sirzech might appear gentle and friendly, but the truth?
Riser dared to say that Sirzech manipulated everyone behind the scenes, using everything, including his family, as his pawns.
Nevertheless, it didn't mean Sirzech could control everyone perfectly.
Sirzech wasn't a robot, and he also made a mistake.
If there was a mistake that Sirzech had made, it would be Issei's protagonist aura that made his wife, Grayfia Lucifuge, take a bath with Issei and leave their child behind to help Issei.
Sirzech was too dependent on Issei, and this was his mistake.
Yet, Riser also couldn't blame Sirzech since he knew that having an obedient tool was comfortable, so Sirzech was a little addicted to Issei and used him for many things, such as dumping all the troublesome matters on Issei.
Frankly, instead of Rias, Riser was more interested in Grayfia since he wanted to see how Sirzech's expression was when his wife was on his hands, yet with the trouble that came afterward, he was too lazy to do it.
He knew that he was like this.
Instead of doing something troublesome, he would spend his day lazily, having a peaceful life.
This was the life that he sought after, yet someone was just too stupid and messed up his life.
Riser might wish for a peaceful life, but if someone asked for a fight, then he believed that he would win.
His position might be at a disadvantage currently, but he knew that he would grow stronger.
"Rias, as I have said to you before, I will be the one who will guide him. Moreover, his purpose in going to the human world isn't to play." Sona looked at Rias helplessly, wondering when this young man gave up on seducing her husband. After all, wasn't it obvious? No matter how many times Rias tried, it would be futile!
However, if Riser knew what Sona was thinking, he could only apologize since he was almost seduced by Rias.
"I know, but isn't it better for us to be together? You are the little sister of Maou Leviathan, and I am the little sister of Maou Lucifer. With the two of us, then they won't dare to mess with us, right?"
Rias calmly answered as she told of the advantages of bringing her along to visit Nurarihyon in Tokyo. She might hate using her status, but right now, she doesn't care about the methods as long as she can join them.
"That's..."
Sona knew that Riser's negative image made it hard for someone to respect him. Even if she stood by his side, the others wouldn't respect her much, but with Rias?
Yet—
"Stop. I don't need to rely on you two to go there. Also, aren't you two busy with events at your school? What was it again? Was it a ball event? You should focus on the event at your school. I don't come to the human world to trouble you two, after all."
"But..." 2x
Rias and Sona were helpless and didn't expect that he would throw them away like this, so they decided to work together, yet—
"No."
His words were unquestionable. "I know my words might hurt you, but I am a man. If I rely on you two, facing all of that while I stay behind you two, everyone will look down on me even further."
While he didn't care much about his reputation if it might bring harm to his women, then he might as well stop becoming a man, yet he would be lying if he wasn't moved by them since even if his reputation became so much worse due of Sirzech, they still believed in him.
So, he knew that he couldn't rely on them and needed to meet Nurarihyon by himself.
As he had said before, in the supernatural world, only strength matters.
In front of the strength, all conspiracy and mocking disappeared since no one wished to die.
Strength was the best thing in this world.
It was also the reason why Issei could get his harem.
It was also the reason why he, Riser Phenex, was sought after by everyone.
But—
[Human world? It's time to let this place know who is the true master of this world.]
[Option 1: Kill all the living creatures in the world. You will receive an "Omnipotent."]
[Option 2: World domination. Rules every being, from non to supernatural beings. You will receive "the Absolute."]
[Option 3: Create a business in the human world. You will receive a "Caligraphy Mastery."]
"..."
As expected of the system, the first and second options were as ridiculous as ever.
