As Masa had made up his mind to go to the human world, while everyone was speechless, nothing could be done to stop him. Well, when they heard that he planned to search for peerage members, no one stopped him since, while his prestige was enough in their domain, naturally, they wished for others to see how majestic their young master was.
Still, before Masa left, he told them what they needed to do, especially with the data storage project, which was connected to all the felines in the Underworld and, if possible, this entire universe.
In the world of Mahouka, Masa created the Isshiki Network, and naturally, Masa also decided to create the Vapula Network, considering its benefits.
This large library project was something that could only be accessed by the devils of the House of Vapula, and at the same time, he intended to collect all the mysteries in this world into this data storage, which would be of great use for all Masa.
Well, this could also become a source of money, too, he thought.
At the same time, Masa thought that it might be good for him to go out to the human world to create his own influence there, especially when Ajuka, Sirzech, and Serafall had their own business in the human world.
After talking with his parents for a while, Masa then let the maids in his house take care of everything as he continued to study the power of the Ton Ton no Mi.
Nevertheless, when he was training, someone interrupted him, which made him turn his head and see a familiar face. He didn't do his training in the room but outside, considering the might of the Ton Ton no Mi wasn't something that could be borne by his own house, so he could only do his training in the mountain near his house. Still, before that, he needed to know the purpose of this beautiful, mature woman with gentle eyes and long brown hair, which she tied in a low ponytail that she rested upon her shoulder, who suddenly came to his training spot.
"Aunty?"
"Masa, I am sorry for bothering you."
"It's fine, Aunty. What's wrong?" Masa looked at his aunt, Misla Bael, who was also the mother of Sairaorg, the heir of the House of Bael, who was also his cousin.
Still, when Masa thought of this fact, he realized that he had a certain familial connection with the Gremory, which made him helpless, yet considering the status of his aunt currently, he knew there was no need to think much about the Gremory.
Still, it might be weird why his aunt was in this place, considering she should be living with her husband, who was the head of the Bael Clan and was also the father of Sairaorg, but everything started with the "Sleeping Disease" that she was caught.
Sleeping Disease.
This was the disease that was caught by some of the devils in the Underworld, and even now, the cause and the solution of this disease haven't been discovered. Still, there was no doubt that this disease had become one of the biggest problems among all the devils, as anyone who was caught in this disease would sleep and be unable to wake up like they were dying.
In the original, his aunt, Misla Bael, was caught by this disease, and Sairaorg decided to call Issei Hyoudo to use his trademark ability, Pailingual, or Breast Language, to talk with Misla's breasts to wake her up.
Unfortunately, this method was unsuccessful, yet there was no doubt that Masa wouldn't let Issei do something as ridiculous as using such a strange and perverted technique on his aunt.
At the same time, in the original story, Masa also wondered how Sairaorg could let his mother's breasts be toyed with by Issei, which made him wonder whether this guy was a man or not.
Was it a desperation?
Or was it because everyone became cuck due to Issei?
Fortunately, while Masa couldn't erase this disease from Misla, the lion-control ability made him able to wake her up. Probably because Misla was also part of the House of Vapula, there was a part of her that was a lion, so she could be controlled by him, and being woken up forcefully by him, so the tragedy where Issei would use his perverted technique on Misla wouldn't happen.
Naturally, this method could only be used by the devil of Vapula, and no one could replicate it except for those with a control-type innate ability, such as House of Furcas, who could manipulate a horse.
Yet, there was no doubt that this made many devils feel helpless as they thought that hope existed; only a few families of devils could be saved from this disease.
Still, there was no doubt that it was the first step for all the devils to escape from this cursed disease, and with their long lives, they should be able to find a way to solve this problem, right?
Masa wasn't sure, but when he thought about Issei, the perverted and idiotic protagonist, he knew that this guy definitely wasn't the one who could solve this situation.
Yes, Issei was powerful, but that's it; except for fighting, he could do nothing.
Yet, probably, in the world of the supernatural, strength was enough, Masa thought, so that was why he tried to become stronger, especially with the power of Ton Ton no Mi.
Still, if there was a reason why his aunt was here instead of her husband's family domain except for her disease, it was also the fact that her husband also got a new wife, who abandoned her, so he made her live within the domain of the House of Vapula.
However, as Misla felt that she had caused trouble for Masa as he needed to be by her side occasionally to wake her up from her disease, she felt responsible for him and often took care of him.
"I have heard that you are going to the human world."
"Yes." Masa nodded. "It's only for a week, though. Do you want me to buy you something?"
"No, it's fine; just be careful and come back safely, okay?"
It seemed that Misla was worried that Masa would go to the human world, so she came to him before his trip.
"You don't have to worry, Aunty. I will be staying with Serafall-sama's little sister."
"Serafall-sama's little sister?"
"Yup."
"I see... then, there is no need to worry then."
Masa saw Misla's expression was slightly weird, yet he decided to ignore it, considering the difference in their age and also her status as the wife of the head of the House of Bael and mother of his cousin, Sairaorg.
After all, even if a devil was known as an evil being, the truth was they weren't that much different from a human, and they had a certain morality within them.
"Still, it isn't a bad idea if you can make Serafall-sama's little sister into your wife, Masa," Misla suddenly said with a teasing smile.
"...it's too early, right? I am still young."
Masa knew that as the heir, it was natural for him to have a fiancee, but he had been pretending to be ignorant since he didn't want to marry someone so early.
Unlike many male devils, who were either playboys or simply untalented, Masa was so talented whether it was his power, government, business, or many others, so he didn't lack female high-class devils who wished to become his fiancee, yet he didn't really want to have a fiancee this early, okay?
"Fufufufu..." Misla laughed when she saw Masa's awkward expression. "Well, Serafall-sama's little sister should become the heiress of the House of Sitri, so she isn't suitable to become your wife as she can't support you fully as your wife, considering her responsibility as an heiress."
Sighing, Masa felt relieved when he heard Misla's words.
"But you should search for a fiancee as soon as possible, so your parents won't be worried about you, who hole up to work or training all the time."
"...I know."
Similar to Rias or Sona, who were troubled by the problem of marriage, Masa was similar. Still, unlike the two of them, he had many suitable candidates, so he wasn't that worried, but the time just wasn't appropriate, and he was young, so he wasn't in a hurry.
"That's good, then. By the way, when are you going to finish your training?"
"I should be over soon."
"Then, I will prepare dinner for you."
"Thank you, Aunty."
"No problem." Misla nodded with a smile, then said, "Then, go ahead and continue with your training, Masa."
Masa nodded and then continued to train the power of Ton Ton no Mi, whether it was to increase his weight or decrease his weight. It was as easy as breathing for him, but to do more variety and further development of this Devil Fruit was his goal, and fortunately, with his unique ability, it was easy for him to develop this ability.
Yet, what he didn't know when he started his training, Misla didn't leave immediately, instead staring at Masa's strong body with eyes that shouldn't be shown by an aunt toward her nephew.
