While Hiromi, Airi, and Shiori came to Tokyo, Masa didn't pn t them to Tokyo but to the nearby city, Yokohama. It might be strange for him t them to the other city as they had arrived in Tokyo, but this wasn't their first time in Tokyo, and they had been to many pces before.

  All of them might have inated from Kanazawa, yet even so, they weren't try bumpkins who had never goo Tokyo.

  Instead, it was because they kokyo well that they didn't pn to go there as they felt bored, sidering there wasn't much differeween this city and other metropolitan cities.

  Department stores, skyscrapers, and many other simir pces cked a distinctive and inality.

  Oher hand, while Yokohama was quite simir, this pce was quite special as it was the biggest atown in Asia. Naturally, this was their destination, and they had fun with all of their might as they would be apart once again after they fihis trip.

  Five days or so.

  It might even be longer, and because of this, whehought of the time they parted, they sighed, but somehow, this was also a spi their retionship since, as they parted, it made their meeting sweeter and more meaningful.

  However, ime, Airi felt that she should e to Tokyo by herself when there were no Shiori and Hiromi, as the two of them made it hard for her to have an intimate exge with Masa.

  "Oh, you are driving a car?"

  It was just that Shiori was surprised when she saw Masa driving his own car.

  How old is Masa again?

  Could he eve a driving lise?

  "If you have money, everything is possible."

  It's the same in any pce; as long as you have money, everything is possible.

  Masa hadn't reached the age where he could get a driver's lise for a car, but even so, there were many ways for him to get it.

  heless, Shiori rolled her eyes and didn't say much, even if the role of a private vehicle wasn't as important as before, sidering how advahe transportation development was, it surprised her when Airi sat by her side on the back seat, giving up the seat o Masa.

  "...you have grown up."

  "I am the big sister, after all."

  Yup, a big sister-in-w.

  The one who would marry Masa was Airi, and this fact didn't ge, making many, especially those close to him, sigh helplessly.

  Regardless, Shiori and Hiromi quickly threw away these depressing thoughts as they wao enjoy this trip as much as possible and fet all the unpleasant problems!

  Still, somehow, as they talked, Hiromi couldn't help but ask, "Onii-sama, do you think immortality is possible?"

  This has bee the talk of the people in the try tely, especially after their families learned a magic that made them youthful aer-looking. Many couldn't help but wonder whether magic allowed oo bee immortal.

  While some people wao die as it was too painful to live, many wished to live forever, especially those who eheir lives.

  Masa might have po create magic that allows oo prolong one's life, but then again, he didn't expect the impact to be so immense.

  Yet, this was also a great thing, especially whei-magic anization had been rampant and beore radical tely, so this talk was a great thing as it could show the importance of the magi to society.

  Still, he had to ahis question first, so after he appeared to be ihought, he nodded. "It is possible."

  "...." Hiromi, Airi, and Shiori.

  "In the Great Asian Union, there should be an immortal."

  "Huh? Really?" 3x

  They might have heard a myth or a legend about an immortal in a, yet even so, despite the existenagic, it was hard for them to believe in such a myth or a legend, but when Masa said so, they khat it really existed.

  "Yeah, they are like ese zombies you see in the movie, though."

  "....." 3x

  Watg their expressions, Masa smiled, but he wasn't wrong sihere were many types of immortality, whether it was by iing their memories into the desdants, being data within the puter, or even being a corpse-like existehat was awoken by the neancer.

  In the description, immortality is when someone is living when they are supposed to die, so those he mentioned above should be included, right?

  After all, even if their forms were different, they were immortal.

  Yet, he also khat the immortality that his little sister asked about wasn't something that he had mentioned before.

  "While I want to say yes, it is hard, especially when we reach a certain period in our lives when our cells will stop dividing as our DNA is damaged."

  When cells stop dividing, in a few days, people would die, but oher hand, if cells tio divide, then we would live forever until the cells stopped dividing.

  The key to immortality was to make the cells tio divide, and this was why Asuha previously asked him whether his magic could trol telomeres since, without them, cells would stop dividing aually die.

  "Then, if we trol these telomeres, we achieve immortality, right?"

  "If it's that easy, then it is good, but if ute the telomeres, a mutation will naturally happen on our DNA, and by then, our entire bodies might be riddled with cers." Masa shuddered as he said, " you imagine having your head to toes covered in cer?"

  "—?!" 3x

  The three girls shuddered with fear and disgust as they imagihemselves covered in cer. With the advances in medical teology, it was easy to treat cer, but then again, cer wasn't like a small disease like a simple flu.

  Yet, there was no doubt that the key to immortality could be found within the cer cells sihe cer cells were immortal.

  However, if the primortality was being haunted by this disease forever and ever, wouldn't it be better to die, then?

  Prolonging life ossible for him, and Masa could do it easily if he wished to with magic, but for immortality unless he could create an Evil Piece from the world of DxD to this world, then it might be hard.

  "There is a jellyfish that live forever or be immortal, and many even did a deep resear this creature, but—"

  "But?" 3x

  "The ce is small since our body is different from a jellyfish, and unlike a jellyfish, we 't return to our youth."

  The way this jellyfish became immortal was by reversing their biological cycle.

  If Masa had to say, it was like a chi could bee an egg when it was about to die, or an elderly person could bee a baby when they were about to die.

  Unless one could perfectly trol their bodies down to their atoms or have time trol, such a method was impossible.

  Yet, even if magic was an amazing thing, once again, it couldn't escape the w of physics, and it could be mimicked by teology.

  If Masa had to say, magic is the ability t about what is possible through sce with supernatural means; although the process is sidered a miracle, the result is not.

  This is why magis were called "sham," and many anti-magic anizations arose since if sce do it, then why is a magi needed?

  'Unless one trol something that is impossible to be trolled by sce.'

  So, as long as a magi was limited by the ws of physics, in the eyes of others, their existence would always be treated as a on.

  Still, let's talk about this problem ter since, for immortality, besides the body, there was oher factor that one o trol, or else everything was meaningless, and this was also ohing that could make people ge the impression of a magi and probably be seen as a god.
