In the human world, in the underground station of Kuoh City, there was a hidden station that connected the human world to the Underworld.
Kuoh City.
There was no doubt that this was a special city in Japan that was being controlled by the little sisters of two Great Four Satans, Sirzech Lucifer and Serafall Leviathan.
At this moment, the little sister of Serafall Leviathan, Sona Sitri, came to this station not to go home to her home in the Underworld but to do the task given by her older sister to take care of her close acquaintance during his stay on the human world.
While this request was unexpected, Sona thought that this might become her brother-in-law, so she was so persistent and definitely wouldn't allow a scumbag to get close to her older sister.
Yes, while Serafall might have a sister complex toward her little sister, which troubled Sona much and caused Sona to appear that she wasn't good toward her older sister, inwardly, she cared for her older sister a lot, so she didn't want her older sister to be deceived.
Fortunately, after a long persuasion (being persistent), she finally, Serafall opened her lips, telling the identity of this "close acquaintance."
Masa Vapula.
The heir of the House of Vapula.
Knowing the identity of the person that Sona needed to take care of instead of Serafall's lover, she thought that this was the attempt of her parents to marry her off. After all, she was clear about the age difference between Serafall and Masa.
Or, rather, Masa was even younger than Sona, yet there was no doubt that compared to all the devils that her parents had introduced to, Masa was the best.
Yes, it was true that Masa was relatively low-key and hardly appeared at social gatherings, but even so, Sona knew Masa well, especially due to Masa's intense promotion of her older sister's show, Miracle Leviathan. More importantly, during his childhood, Masa also appeared in the Miracle Leviathan, performing as a child actor for a while.
Sona had also seen Masa, but that was during his childhood, and many years had passed, so she didn't know how he had become.
However, for her, who was the heiress of the House of Sitri, it was easy for her to gather Masa's information, and she knew well that he was the strongest devil of the House of Vapula.
Was this her new fiance candidate?
When Sona thought of this, she felt a little conflicted, not only because Masa was younger than her but also because she didn't want to marry yet, especially when she had a dream that she had to achieve.
However, there was no doubt that Masa's attempt to visit the human world gave her a good impression of him, especially when the majority of devils with high status looked down on the human world and those who lived there.
Yet, if Masa wished to become her fiance or her future husband, then it was still too early.
Nevertheless, even so, she didn't forget her etiquette and brought all of her peerage members to welcome Masa. After all, there was no doubt that compared to her best friend's fiance, Masa's status was so much better.
Still, while Sona didn't say much about who they would all welcome except for her Queen of her peerage, Tsubaki Shinra, no one could help but be curious.
"Sona-sama, who are we welcoming?"
Unlike her best friend's peerage members, who treated each other like family, the hierarchy of Sona's peerage was clear, and everyone was respectful toward Sona, who had given them a chance to change or become stronger.
"Hmm?"
However, Sona appeared to be distracted and didn't hear their question. "Sorry, can you repeat your question?"
"....."
Everyone somehow also became nervous since this person that they would welcome could make their master, Sona, who had always been cool and distracted.
"Um... who are we going to welcome, Sona-sama?"
Nevertheless, this also increased their curiosity even further.
"Oh, it's my older sister's close acquaintance."
"What?! Leviathan-sama's close acquaintance?!"
Everyone became so nervous when they heard that since it meant that this devil was going to be a big wig!
Someone with such a high status before them!
Once again, unlike her best friend, Sona explained to all of her peerage members what to do and what not to do, including the difference in status among all the devils. They were just reincarnated devils, and they knew how low their status was compared to the big wig, so they somehow became a little scared, knowing that they had to be very respectful toward this person. Oh, this devil!
Sona also noticed their nervousness, so she said, "You don't have to be so nervous. This person is about the same age as us, or rather, he should be younger than all of us."
"He? Eh? He is a boy?"
"Younger? Then he should be in the first year of high school?"
"Is he cute?"
"...."
The last one aside, suddenly, the pawn of Sona Sitri, Saji Genshirou, became so nervous. After all, he held a feeling toward his master, who had given him and his family a chance to be a better person, so hearing that a young man about the same age as them to come, he wondered whether this person was her master's boyfriend or fiance, which made her helpless, yet he also knew the difference of their status, which made him even more helpless.
Sona ignored their questions and explained, "His name is Masa Vapula. He is the heir of the House of Vapula. You can say that he has helped many of my older sister's businesses and is like her right hand."
"..."
Everyone was dumbfounded when they heard Sona's explanation since someone about the same age as them had become the right hand of one of the most powerful devils in the Underworld, which made them realize that they lived in two different worlds!
Still, once again, due to how exceptional he was, they also became even more curious about what kind of young man this devil was.
"But, House of Vapula? What kind of a devil comes from that house, Sona-sama?"
All of them were clear about the devils of the House of Gremory and the House of Sitri, but the House of Vapula?
They weren't sure, especially when all of them were just high school students.
"The devil of the House of Vapula is a devil that has the power to tame and control a lion."
"Lion?"
Hearing that explanation, it was hard for them to understand as the only lion they had seen was the one from the zoo.
Yet, they knew that no matter what, they had to greet Masa with the highest respect, so after they knew what to do, they quietly waited until his train came.
Still, when this train came, all of them were nervous, especially Saji, who was a bit worried about the unclear relationship between Masa and her master, Sona.
Yet, Saji wasn't the only one since Sona was also nervous since Masa was probably her fiance candidate, and as a young woman, how could she not be nervous, okay?
Nevertheless, everyone stood straight, waiting for Masa to appear, and when he appeared, they felt they had lost their voice—
"Are you Sona Sitri? Nice to meet you. My name is Masa Vapula."
"....."
This guy... wasn't he so handsome?
