As Masa had made up his mind to go to the human world, while everyone eechless, nothing could be doo stop him. Well, when they heard that he po search for peerage members, no oopped 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 o do, especially with the data ste project, which was ected to all the felines in the Underworld and, if possible, this entire universe.

  In the world of Mahouka, Masa created the Isshiki work, and naturally, Masa also decided to create the Vapu work, sidering its bes.

  This rge library project was something that could only be accessed by the devils of the House of Vapu, and at the same time, he inteo collect all the mysteries in this world into this data ste, which would be of great use for all Masa.

  Well, this could also bee a sourooo, 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 influehere, especially when Ajuka, Sirzech, and Serafall had their own business in the human world.

  After talking with his parents for a while, Masa thehe maids in his house take care of everything as he tio study the power of the Ton Ton no Mi.

  heless, when he was training, someoerrupted him, which made him turn his head and see a familiar face. He didn't do his training in the room but outside, sidering 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 o 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 b you."

  "It's fine, Aunty. What's wrong?" Masa looked at his aunt, Mis Bael, who was also the mother of Saira, 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 e with the Gremory, which made him helpless, yet sidering the status of his aunt currently, he khere was o think much about the Gremory.

  Still, it might be weird why his aunt was in this pce, sidering she should be living with her husband, who was the head of the Bael d was also the father of Saira, 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 bee one of the biggest problems among all the devils, as anyone who was caught in this disease would sleep and be uo wake up like they were dying.

  In the inal, his aunt, Mis Bael, was caught by this disease, and Saira decided to call Issei Hyoudo to use his trademark ability, Pailingual, or Breast Language, to talk with Mis'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 teique on his aunt.

  At the same time, in the inal story, Masa also wondered how Saira 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 Mis, the lion-trol ability made him able to wake her up. Probably because Mis was also part of the House of Vapu, there art of her that was a lion, so she could be trolled by him, and being woken up forcefully by him, so the tragedy where Issei would use his perverted teique on Mis wouldn't happen.

  Naturally, this method could only be used by the devil of Vapu, and no one could replicate it except for those with a trol-type innate ability, such as House of Furcas, who could manipute 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 whehought about Issei, the perverted and idiotic protagonist, he khat this guy definitely wasn't the one who could solve this situation.

  Yes, Issei owerful, but that's it; except fhting, he could do nothing.

  Yet, probably, in the world of the supernatural, strength was enough, Masa thought, so that was why he tried to bee 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 Vapu.

  However, as Mis felt that she had caused trouble for Masa as he o 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 yoing to the human world."

  "Yes." Masa nodded. "It's only for a week, though. Do you wao buy you something?"

  "No, it's fine; just be careful and e back safely, okay?"

  It seemed that Mis 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 o worry then."

  Masa saw Mis's expression was slightly weird, yet he decided to ig, sidering the differen their age and also her status as the wife of the head of the House of Bael and mother of his cousin, Saira.

  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 make Serafall-sama's little sister into your wife, Masa," Mis suddenly said with a teasing smile.

  "...it's too early, right? I am still young."

  Masa khat as the heir, it was natural for him to have a fiancee, but he had beeending to be ignorant since he didn't want to marry someone so early.

  Unlike many male devils, who were either pyboys or simply ued, Masa was so talented whether it was his pover, business, or many others, so he didn't ck female high-css devils who wished to bee his fiancee, yet he didn't really want to have a fiahis early, okay?

  "Fufufufu..." Mis ughed when she saw Masa's awkward expression. "Well, Serafall-sama's little sister should bee the heiress of the House of Sitri, so she isn't suitable to bee your wife as she 't support you fully as your wife, sidering her responsibility as an heiress."

  Sighing, Masa felt relieved when he heard Mis'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."

  Simir to Rias or Sona, who were troubled by the problem of marriage, Masa was simir. Still, uhe two of them, he had many suitable didates, 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." Mis nodded with a smile, then said, "Then, go ahead and tih your training, Masa."

  Masa nodded and then tio 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 whearted his training, Mis didn't leave immediately, instead staring at Masa's strong body with eyes that shouldn't be shown by an aunt toward her nephew.
