It was crazy for him to choose "Option 1" and "Option 2," especially when Riser knew that even if Sirzech was the strongest devil, it didn't mean Sirzech was the strongest in the world.
There were still many existences that were above Sirzech.
Even if Riser might be as strong as Sirzech in the future, he wouldn't think to control the world unless he was able to control the Underworld first.
Though such a day might not appear since after he controlled the entire Underworld, he might only spend his days lazily, depravedly. After all, dominating the world had never been his purpose.
Peace of mind.
This was his only purpose.
Still, more importantly, he needed to handle his quest.
Since he had chosen "Option 3," then he would make a business. Still, unlike before, he wouldn't do serious business since he realized that as long as he did business, even if this business was a fraud, he would complete the quest.
Moreover, the reward was just so-so, so why did he have to do this quest with a serious attitude?
Or rather, if he could take it easy, why should he work hard?
[...] System.
"Well, enough about this. Can you tell me what you usually do in the human world?" Riser asked curiously since that way, he could find a clue as to what kind of fraud business he should do.
"....."
Sona and Rias could only show a bitter smile. His decision couldn't be changed, so they could only follow his words reluctantly.
However, there was something that made Rias feel weird. "...you are curious about what we are doing in the human world?"
As Riser's former fiancee, Rias knew how much Riser disdained the human world. In his eyes, the human world might not be different from a slum. It was full of piss and feces. Yet, he asked them what they usually do in the human world.
Rias was in shock and realized how big the change in Riser was.
Nevertheless, Sona was calm and told him what they usually do in the human world.
Their activity was rather simple since they either went to the school, received a mission to hunt a stray devil, or did their job by making a contract with a human.
"Is it common to see stray devils in the human world?" Riser had never taken the human world seriously before, and his life had always been in the Underworld.
In the Underworld, while there was a stray devil, all of them were killed swiftly before they even made a noise. Yet, this was normal since the Underworld was where the devil was living, but what about the human world?
"Unexpectedly, there are a lot of them."
"Yeah, we received a lot of missions to eliminate a stray devil."
"Not everyone can treat their servants kindly after all..." Riser murmured, hearing their answers.
Whether Sona or Rias had often received a mission to hunt down the stray devils. Still, as for why those devils had gone astray? The two of them knew it was mostly due to their master, yet as someone from a high position and the same position as those masters who treated their servants horribly, they didn't care about those stray devils.
If the reincarnated devils dared to betray their masters, then death was only their destination.
There was no "if" or other option unless these servants were powerful enough to run away or had a talent, so the other powerful devil took an interest in this reincarnated devil and employed them as their new servants.
However, such a case was rare or almost impossible to see since the price of betraying the master was only dead.
If someone made an exception, then it would ruin the rules of the high-class devil.
Still, even if some stray reincarnated devils could be saved, then they had to change their identity.
If Riser had to give an example, it would be like Koneko Toujou. Even though Koneko didn't commit any crimes, her older sister killed her master, so as long as Koneko had an involvement with the criminal, there was no chance of being saved.
However, Gremory took Koneko and made her into Rias's peerage members, but as expected, it was impossible for her to maintain her real name, so that's why her name became Koneko Toujou.
"Still, are those stray devils stupid enough to visit the Kouh Town instead of hiding well?"
After all, even if there were a lot of devils, it didn't mean their numbers were enough to cover every corner of the world.
"Unexpectedly, there are a lot of them who come to hide in Kuoh town."
"Now, I wonder why they did that..."
Rias and Sona only realized how stupid those stray devils who came to hide in the Kuoh town where the little sister of Sirzech Lucifer and Serafall Leviathan were living.
Weren't those stray devils just courting death?
However, Riser only rolled his eyes, thinking that it might be the work of the devils under the Gremery house and the Sitri house, who pushed those stray devils on the Kuoh town, giving a chance for Rias and Sona to gain experience and also achievements.
Riser lost interest in this matter, so he asked the other matter.
"What about the contract? You make a contract with a human, right?"
Frankly, Riser had never made a contract with a human, but why should he? The only ones who would contract with a human were those with a low status.
Nevertheless, in some cases, it was possible for those devils with a high position to make a contract with a human. Still, if a human wanted to make a contract with such a high-status devil, the identity of this human should be remarkable enough to make the devils with a high position be tempted like King Solomon in the past, who made a contract with all 72 Pillars.
This was the case with Sona and Rias since they only took the contract with someone with a high position in the human world. However, in the case of their peerage members, they could only scramble by anything, without caring who had made a contract since, as a reincarnated devil, their talent in seducing someone was relatively low.
"Do you want to make a contract with someone?"
"I just want to try."
Riser felt that this was a good business. He only needed to throw one summoning paper so the human could summon him to make a contract. As for whether he would answer or not would depend on his mood, but this should be counted as a business, right?
[Congratulations, you have received "Caligraphy Mastery"]
"...."
While he had expected this, he felt speechless by how easy it was for him to get a reward.
[Everything is only difficult in the beginning. When your position is higher and stronger, it will be even easier.]
Riser nodded and thought that it was normal since, due to the difference of position, the value of something in the eyes of people might change.
It was like a car.
For a normal person, it might be expensive, but for the owner of an oil well in the Middle East, it was a toy.
—or when one had earned their own money, they felt that the value of a certain item was cheaper than when they were still relying on their pocket money.
In conclusion, his hard work was paid, and it was easier for him to get his rewards.
"Is it okay? Kuoh town is your town, right?"
"It's okay. I don't mind." Rias answered kindly and was happy that she could do something for him.
"....."
Riser thought that having someone to lick him was good.
"Riser-sama, are we going to make a contract with a human too, nyaa?"
Ni and Li looked at their master curiously. However, as long as it was the wish of their master, they didn't mind making a contract with a human, even though it was a little troublesome.
"No, it's okay. You don't need to. I am just doing it out of curiosity." Riser then looked at Sona and asked, "By the way, do you have a paper with you, Sona?"
Sona wanted to give a paper so Riser could make a summoning contract, but Rias beat her first.
"Here you go."
Rias gave a paper to Riser with a smile.
Meanwhile, Sona was speechless.
"...thank you."
Being licked by Rias was good, but Riser had a hard time getting used to it, especially when he thought about how she acted before. Still, it was bothersome to think too much, and he should enjoy her lick well.
*Pero~! Pero~! Pero~!*
Riser shuddered for some reason, but after he took the paper, he could feel her palm lightly brushed against his.
"....."
He looked at Rias, who still had this gentle smile on her face, and thought that he should sue her for sexual harassment, but he knew that he would have a disadvantage in court, so he refrained from talking and just enjoyed the benefit that came from Rias.
"Thank you."
He took the paper and then wrote down the magic circle to summon and also an English instruction on the back of the paper.
Nevertheless, everyone who saw him writing was in a daze since they could feel how refined and elegant he was when he wrote on paper.
"........."
Rias bit her lips and felt even more unwilling.
"..did you learn calligraphy, Husband?" Sona asked curiously and in amazement.
"No. This is how I normally write."
"..........."
Was this his talent?
Nevertheless, Riser realized the "Calligraphy Mastery" seemed able to make him create a magic circle faster so that he could activate his magic almost instantly. His ability to cast spells was probably as fast as pulling a trigger on the gun. Moreover, this ability also made him able to understand all languages, including the lost language.
'No matter how strange the reward is, they're all amazing.'
Even his "Boxing Mastery" that he received previously also made him able to predict the future attack based on the motions and physiology of the opponents.
By adding "Mathematic Mastery," it might not be wrong to say that he really could see a few seconds of the future.
Still, while his "Calligraphy Mastery" attracted their attention, Riser changed the topic again, causing them to talk about many things in the human world. Due to their conversation, the time seemed to move faster, and they didn't realize they had arrived.
Still, Riser felt a little emotional since it would be his first time to come to the human world.
His mood was good and excited, but—
"You bastard! What are you doing here?!"
"....." Riser.
