Complex

"Huh? Really? You want to go to the human world, Masa-chan?" 

"Yeah." Masa nodded and asked, "Can I?" 

"Sure, why not~? But it's your first time there, after all. Are you going to be alright? The Underworld and the human world are different, you know?" 

While some devils entered the human world, it didn't mean that they were comfortable staying in the human world. The human world and the Underworld were different, after all, and for a devil, it was more comfortable to stay in the Underworld; due to the influence of many religions, many devils would find it uncomfortable to stay in the human world as anything that was related to light and holy were the weakness of the devil, who was a creature of darkness. 

Considering Masa's nature, who was a bit similar to a shut-in as he mostly stayed in his domain and just visited others when he needed to, his decision to go to the human world surprised Serafall the most. 

Still, if Masa knew that Serafall compared him to a shut-in, he would be speechless, yet even so, could he be blamed? 

His domain was massive, especially after his aunt married the current head of the House of the Bael, the house of the Great King of the Devil, which increased the domain of the House of Vapula as the head of the Bael gave his house those territories for dowry. 

Frankly, before Masa appeared, those territories were simply untreated as the territory of the domain of the House of Vapula was enough. More importantly, the Underworld was immense, and it was as huge as the human world, or even more so, yet the population was so low that you would be surprised.

Still, he was probably young and was thinking of staying in his domain all the time, so he did many things to make his place better, and fortunately, his effort bore fruit.

So, there was no doubt that Serafall was surprised when Masa told her that he wanted to visit the human world since she thought that Masa would be like a lion or a tiger who stayed on its mountain. 

"Do you think I am weak?" 

"W-Well, I know that your strength is okay, but the human world isn't so simple, you know? There are many factors that you need to watch out for, or rather, why do you want to go the human world?" 

"I want to see whether I can find someone to be part of my peerage." 

Peerage. 

This term might have been unfamiliar before, but after the creation of the Evil Pieces by Ajuka Beelzebub during the 16th century, a devil was able to reincarnate any living beings into a devil to become part of their family or group. 

As for why this family or group was being called a peerage, it was because the Evil Pieces that Ajuka created were similar to chess pieces, which was why this group of reincarnated devils made by a high-class devil was called a peerage. 

Masa naturally had a full set of Evil Pieces, but he hardly had any interest in them before. Now, it is different, so he thought of going out to the human world to search for a peerage group. 

Naturally, while he planned to search for peerage members, this wasn't his priority as his purpose in the human world was to devour an angel or a fallen angel to add a holy property within his Pika Pika no Mi. 

However, he could use the peerage as an excuse to go to the human world. 

"Ah, you have finally shown an interest in the Rating Game, huh? If that's the case, then this Serafall-oneechan will help you!" 

After the creation of the Evil Pieces, an event known as the Rating Game was introduced in the Underworld among the devils, which was a type of competition between two devils. 

Frankly, in Masa's mind, this game was nothing but just an event to make the long life of the devils more interesting, and at the same time, it also gave a chance for a devil to raise their status by showing their power in this game. 

However, for him, who had a high status, he didn't have much of an interest as winning this event wouldn't bring him much benefit except for social standing. 

Masa had money, came from a noble family, and was also the heir of the House of Vapula, so what was the use of social standing? 

More importantly, instead of showing off his power, keeping everything low-key was what he sought. 

Frankly, not many devils knew how strong he was, but those who knew... knew that he could reach the Ultimate Class Devil if he wished to, as he had become the pinnacle devil of the House of Vapula. 

Still, Serafall's support surprised him. "Is that okay?" 

"Um, why not~? You want a good member, right? Then, going to the human world is a good thing. I will call So-tan later; you can go visit Japan." 

"So-tan? Japan?" 

"So-tan is my little sister~! Did you forget~?" 

"You don't mention her much when we are together, after all." 

"Now that you mention it, I hardly talk about So-tan with you, Masa-chan, but don't fall for her, okay? She is off-limit, okay~?" 

"I know." 

Masa knew that Serafall was a sister complex, and he also didn't plan to seduce Sona Sitri when he went to the human world. Still, there was something that he wanted to ask. 

"By the way, why Japan?" 

"Hmm... it's hard to answer if you ask that way, but strangely enough, many unique individuals come from this country, and they are so loyal if you can get them." 

Japan was a unique country as it was probably the only country that had a life employment system, so the moment one joined a company, they wouldn't be laid off and could continue their job till their pension without worry. 

In other words, as long as one was working in this country, it would mean stability, and this also led to many being loyal to the place where they worked. 

A peerage or becoming a reincarnated devil was one form of employment, so compared to working under a Japanese company, which had many strange rules within, it was far better to work under Masa, who was the heir of the House of Vapula, right? 

Still, it was also Masa's first time to go to the human world, so Serafall thought that it might be better for him to have a guide, and her little sister was a perfect candidate for that as her little sister had been living in the human world for a few years. 

As Serafall explained what Masa needed to watch out for in the human world, Masa also listened carefully and asked something that he didn't understand. 

Nevertheless, there was no doubt with Masa's current strength; even if there were many dangers in the human world, it wouldn't bother him much. 

Still, they didn't end their conversation right away and talked about many things since Serafall also wanted him to buy her some souvenirs when he went to the human world. 

"Then, see you in a week, Masa-chan~! Don't forget my souvenirs~!" 

"Okay, leave everything to me." 

"Muwah~! Muwah~! Muwah~! See you~!" 

"....ah, see you." 

"Where is my kiss Masa-chan?!" 

"Ah, the signal is bad. I am sorry, Onee-chan." 

It was impossible for him to give such a shameful kiss, so he quickly ended the call with an awkward excuse before he looked at his phone with a complicated expression. Letting out a helpless sigh, he wondered what he should do. 

Nevertheless, Serafall didn't get angry at Masa's action and just thought that he was shy as he was no longer a little cub, which made her smile. Still, she didn't forget about his request and quickly called her little sister. 

As expected, the moment she made a call, her little sister quickly answered her. 

"...hello?" 

"Ah, So-tan~? How are you~? Onee-chan misses you so much~! Muwah~! Muwah~!" 

"...I will close the phone." 

"Wait~! Wait~! I have a request for you~!" 

"A request?" 

This time, So-tan, Serafall's little sister, was surprised by Serafall's words, but her expression quickly changed, and she asked, "...do you want me to buy Mahou Shoujo's toys again, Onee-sama?" After all, this wasn't the first time for Serafall to ask her to buy toys, which made her helpless. 

"No~! No~! My..." Serafall fell in silence, wondering how to describe her relationship with Masa. In the past, she thought of him as a cunning little boy who just wanted to use her influence, and she decided to humor him since he was cute, yet unexpectedly, he helped her with many things, and he also grew up into a man who matched of her status, which made her—

"My?" 

"Well... it's hard to describe our relationship." 

"..." So-tan.

"Anyway, I need you to help take care of him later when he goes to the human world, okay, So-tan?" 

"Huh? Him? You are close with a man now?" 

"Ah~! I am a bit busy now~! Anyway, take care of him, okay~! He will come tomorrow~! Thank you, So-tan~! Muwah~! Muwah~!" 

"Wait, Onee-sama!" 

Yet, the call hung, and So-tan looked at her phone in a complicated mood before she changed her gear and showed a solemn expression, thinking of the person who was entrusted by her elder sister to take care of when he came into the human world. 

Who was he? 

This thought made her spend a sleepless night, wondering what kind of man had made her older sister that way.
