Sense of urgency!

"Thank you, Sona-nee." 

Finally, a week had passed, and it was time for Masa to go back to the Underworld. Naturally, he wasn't alone, as Asia would come with him. Frankly, he thought that she would stay in the human world, considering she had befriended Sona's peerage members, making them into friends.

If Masa had to say, it didn't matter where Asia would stay, whether it was in the Underworld or the human world, or rather, it was probably better for her to stay in the human world, but Asia vehemently said, "I will go with Masa-sama!" 

Yes, Asia started to use the "-sama" suffix on him since Sona had reminded her that Masa had a high status and if she didn't want to get into the bad side of his family, she needed to show her respect to Masa, at least in front of his family, as there was no doubt, his family was particularly sensitive toward this issue as he came from a noble family.

Whether it was Masa, Sona, or Rias, neither of them cared about this problem, but their family was different, so Sona thought to remind Asia, especially when she had thought of her as part of a family, considering... well... it was clear, right? 

Still watching, ready to leave and go back to the Underworld, Sona felt her heart tighten somehow. The time they spent together might not have been long, only a short week, yet even so, he had shown her many things and the feelings that she had never felt before also started to bloom. 

At the same time, she was sure that Masa didn't know that anyone who could defeat her in chess would become her fiance, yet, as expected, it was hard for her to be the one who brought this issue up as she was a female. 

Nevertheless, there was no doubt she was reluctant to leave him, especially when she thought of the days they spent together, playing chess, eating many delicious foods, then spending their time visiting various places. While they might not have been alone, she enjoyed that time. 

"...okay."

"Are you going to miss me, Sona-nee?" 

Usually, Sona might make a curt comment to hide her shyness, but it seemed she was really sad. 

"I will also visit the human world from time to time, and if you have time, how about you visit my place? I will welcome you there." 

"...is that okay?" 

Sona was surprised, but she didn't reject this idea, realizing that she could visit Masa, too. 

"Sure." 

Masa nodded and said, "You might even meet Serafall-sama since she often visits my place."

"...let me think about it again." 

Sona didn't mind visiting Masa's place even if his parents were there, but if there was Serafall... she felt that she might as well wait for Masa to come to the human world, especially since she knew that Masa had started a business in the human world. 

"Then, see you later." 

"See you later, everyone." 

Leaving those words, Masa and Asia left the human world and went to the domain of the House of Vapula. 

Still, even if Masa had left, Saji couldn't be happy since he knew well that his love would never bear fruit, especially when he saw Sona's current expression, who had just watched the train in which Masa and Asia had entered a daze. 

On the other hand, watching her master, who had stood for a while in silence, Tsubaki asked, "Are you okay with this, Sona-sama?" 

"Hmm? What do you mean, Tsubaki?" 

This sudden question woke Sona up. 

"I am not sure why you thought of him as your fiance, but I can tell that Masa-sama is an exceptional man. If you are not being clear about your relationship, then I am afraid other high-class devils will make a move on him first." To be honest, it was hard for Tsubaki to say this, but she knew what her mistress was feeling toward Masa, and instead of waiting, she felt like Sona should make a move. 

"If I have to be honest, with Masa-sama's excellence, it is easy for him to search for a fiancee, and those women of high class will be more than happy to become his fiancee. If you don't make it clear, then you might lose him." 

Tsubaki felt that Sona should make everything clear or else—

"...that's a bit too much, right?" Sona was stunned, but then she shook her head softly. "He is still young, after all, and there is no need for us to be in a hurry." 

Yup, there was no need to be in a hurry, and everything could wait slowly; after all, they were just in high school, yet what she didn't know was that her decision to wait might make her have extreme regret in the future. 

Meanwhile, Masa, who was within his family's luxurious magic train, thought that his days in the world of humans gained him many benefits, especially when not only did he get Asia but also became a fallen angel with 12 wings. 

Yes, 12 wings. 

As he had devoured Dohnaseek previously, then along with Kokabiel, Masa had 12 wings, which showed that he was the best of the best among the fallen angels. 

At the same time, he also thought that the difference between ten wings and 12 wings wasn't that much different. 

Still, as he thought about this problem, he knew that if the next Masa appeared and Masa from One Piece got the Zoan type of Devil Fruit that he wished to be, then this plan could succeed. 

As he devoured someone with the power of the Jake Jake no Mi, Masa could gain the traits of the ones that he devoured. 

So, if he combined his body that had eaten that "certain type of Devil Fruit" with the DNA of those that he targeted, then logically, it should be possible for him to evolve, right? 

Still—

"Masa-sama, what should I watch out for when we arrive at the Underworld?" 

Masa looked at Asia, who was clearly nervous, and said softly, "There is no need to call me "-sama" again. There are only the two of us." 

Asia blushed, but she shook her head softly. "No, I need to get used to this since I don't want to get a bad impression after all..." 

"Asia..." 

Masa smiled and patted her head softly, and she closed her eyes, clearly enjoying his touch. 

Still, Asia also felt a little conflicted, realizing that Masa was one year younger than her, but she was the one who acted childish before him, but... but... let's enjoy this touch first, and acted like an older sister later. 

'Asia-oneechan!' 

Somehow, Asia felt her face burn hot when she imagined Masa, who was rugged and manly, would call her intimately like that. 

Masa wasn't sure what Asia was thinking, but he knew that this nun wasn't as pure as he thought to be, and she had these pervy thoughts from time to time. Her knowledge might be limited due to her upbringing, but after she got to know Sona's peerage members, she got to know something known as health and physical education. 

After all, not only guys but also girls were perverted, and watching Masa's immense body, which was huge, especially in a certain area, still gave him a gentle charm, and many were directly smitten by him. 

This was the advantage of being handsome; there was no need to do much, and many would fall quickly, especially when Masa was also an attractive, talented businessman and powerful. 

In other words, he was an overbearing CEO in the story.

Moreover, as long as someone tasted "that," even a fallen angel who hated a devil so much would directly fall to him. 

So, there was no doubt Asia didn't wish to part away from Masa and wished to make a good impression on his family. 

Frankly, she should have been nervous, but fortunately, Masa knew what she was worried about and comforted her. Yet there was no doubt as long as everyone knew her ability, no one would reject her since this was how important her ability was for everyone. 

Healing. 

This was a rare and important ability. 

Nevertheless, their trip was nice, and the two talked about many things until they arrived at his domain, which made Asia dumbfounded as his domain was as immense as the Persian Empire at its peak.

Many might say that Masa's domain was too huge, especially when the Gremory family, which was the family of Sirzech Lucifer, the current Lucifer, was just about Honshu Island in Japan.

Masa said otherwise since the House of Gremory wasn't a noble family with a high position. 

More importantly, the current Four Great Satans were nothing but just a symbol, or even rude, a mascot. 

On the other hand, Masa's family, the House of Vapula, had a close connection to the House of Bael, who was the leader and the king of the Underworld, which made many things convenient. 

Even if his aunt's relationship with her husband wasn't that close now, the fact that they married didn't change, and because of this, his family was greatly supported, especially when everyone also had seen his talent. 

Lastly, as Masa had said before, with how low the population of the devils, this was nothing, he thought, especially when there wasn't even a sea within the Underworld, so there was no doubt that every noble family had a large domain on their own. 

Still, as they returned to his domain, Masa saw a charming, mature woman welcoming him. 

"Masa!" 

Misla Bael sighed and then smiled when she saw Masa had arrived, but she stopped when she realized he hadn't returned alone. 

Yet, Misla wasn't the only one since there was this cute girl who also came and welcomed him with an annoyed expression. 

"Masa, why didn't you invite me to go to the human world—" 

However, similar to Misla, the girl stopped and looked at Asia with confusion. 

"This is...?" 2x

Masa coughed and then introduced Asia to everyone. "This is my bishop, Asia Argento." 

"N-Nice to meet you! I-I am Masa-sama's bishop! Asia Argento!" 

"...." 2x

Yet, there was no doubt that as this cute girl known as Asia appeared, a hint of urgency appeared in their minds. 

Still, this was a problem that Masa of DxD had to solve by himself, and Masa of One Piece was glad that his Pika Pika no Mi had gained holy property. 

So, let's test it first. 

"Perona, attack me with your ghost!"
