Artificial Sacred Gear.
This was probably the best thing that Azazel had created and achieved in his life.
Masa, who did research on the Sacred Gear, also understood how amazing Azazel's feat was. Yes, he might be able to create the Sacred Gear, but it was by using the Baku Baku no Mi by swallowing a living being and a certain item and combining it into one, and by the knowledge of the Devil Fruit from the world of One Piece.
Still, if there was a reason why the research of the Devil Fruit in the world of One Piece was more advanced than the research of the Sacred Gear in the world of DxD, Masa knew the answer, and that answer was it was because the existence similar to a Vegapunk didn't exist.
Unlike Vegapunk, who even made his own clones so he could focus on his research, Azazel was a fallen angel, so it was impossible for him to give all of his time to the research.
More importantly, Vapapunk is a human.
While it might seem weird, Masa also understood why humans were an amazing species. The time of humans was limited, and they weren't immortal like him, who was a devil, so during those moments, they tried to show their sparks in their lives.
On the other hand, the devil had almost unlimited time, so they had a lot of free time, and even if they were lazy and slept for hundreds of years, it didn't really matter, so they didn't use their time well, and their thought toward the time was different from a human.
However, unlike the old generation, the new generations of supernatural beings had their thoughts affected by humans, so they worked hard toward their ambitions with their might if they discovered their interests.
This was also the reason why Azazel, who was older, wasn't as good as one of the Four Great Satans, Ajuka Beelzebub, who could even create an Evil Piece, a tool that allowed another creature to become a reincarnated devil.
Masa was the same as he had been working hard to become stronger.
Yet, at the same time, similar to a vile being, whether it was a fallen angel, a devil, or even a human, while some of them were exceptional, the majority of them were shitty.
No one is perfect, and frankly, the word "perfect" is also such an abstract subject as the definition of perfect is different for everyone. It is different from a human or a bird, which everyone, no matter what their race is, can describe.
Still, Masa didn't feel regret about devouring Azazel, especially when it was hard for him to trust this guy.
Unlike the original protagonist, who only thought by using his lower body, so as long as someone was gentle to him, he wouldn't think of anything.
However, Masa knew that he couldn't treat Azazel in such a way, especially unlike Issei, who was just a normal human in the past. Masa was a pure-blood devil, which made him and Azazel feel a sense of disgust for each other despite the fact that they didn't know each other in the beginning. The fact that their races had been fighting from the time of the creation of humans also made his suspicion toward Azazel hard to erase.
If Masa had to be honest, he had never ever thought to kill Azazel, to begin with, but it was different when he found out the fact that Raynare, Mittlet, and Kalawarna remained silent and never exposed him even after they were tortured by Azazel.
While they called his name in the end, it was because they knew Masa could handle all the problems, so after all of that, how could they let go of Azazel?
Yes, Azazel might be an important character in the world of DxD, but so what?
Masa could even take the Boosted Gear and even kill Issei, so why should he hesitate to kill Azazel?
Or rather, it had become a unique culture of every supernatural being to kill each other, no matter how important one's role is to the world.
If Mas had to give an example, Zeus even killed his father, Kronos, before he became the King of Gods, right?
As for what would happen in the future, in the worst case, the world would be in chaos, and each of the supernatural beings would fight each other, yet Masa thought that it was fine.
Yes, Masa might not be the strongest, but even so, he was still within the Top 10, and probably, he was already above Sirzech, who was the strongest devil in this universe, but overall, his power was good enough, as he was just below Indra and Shiva.
As for the Dragon Gods, such as Ophis and the Great Red, Masa knew that it would be a long time before he was able to reach such a strength. Still, after he had killed Azazel and devoured him, what should Raynare, Mittlet, and Kalawarna do?
"...just go back?" 3x
The three fallen angels stared at Masa speechlessly, thinking that this guy was a scumbag!
After what this guy had done, tainting their bodies with his cloudy white liquid, tormenting their bodies till they took on his shape, was he going to abandon them just like that?
"Masa-sama, don't leave us!" 3x
The three clung to him tightly as their hands naughtily moved to his lower body, hoping that he would change his decision.
"Calm down. I am not going to abandon you."
"But we have nowhere to go!"
"You have."
"Where? Your place?"
"No, the fallen angel, Grigori."
"....." Raynare, Mittlet, and Kalawarna.
Kalawarna, who was the soberest, mature, and calm among the three, took a deep breath and said, "I know that my words might be presumptuous, Masa-sama, but you have killed Azazel for us, so how can we go back to the Grigori?"
"...."
Still, Masa had to say that the three were merciless as they didn't care about Azazel's life and death, but then again, as Azazel wanted to kill them before, he knew that even if Azazel was their respected leader in the past, Azazel became dead in their minds after they were tormented by Azazel.
"No, you can go back to Grigori."
"...why you are so confident, Masa-sama?" Mittlet was confused as to why Masa believed that the three could go back safely.
"Because you three are too weak."
"..." 3x
Somehow, even though they knew that it was a fact, they wanted to smack Masa with all of their powers, even if they knew how meaningless it was!
Yet, this was the fact.
The three of them were too weak, so who would think that they could kill Azazel or even get involved with someone who would kill Azazel, especially when their previous image had always made them appear to worship, respect, and love this leader of the fallen angel?
More importantly, Azazel acted on his own to catch the three, as he had never expected that Masa would come so soon.
Yet, Masa, who had gained the Wapu Wapu no Mi, could go anywhere in this universe as easily as he breathed, and of course, no one would be able to tell that he was the one who did all of this as he was a devil from the House of Vapula.
Still, even if Raynare, Mittlet, and Kalawarna returned, nothing would happen. Instead, they could go back to normal as if nothing had happened.
"In the worst case, I will just come to your side like before."
"Well, that's true..."
While Raynare's nail was pulled by Azazel, Masa quickly came and saved them, then killed Azazel instantly, so they knew that even if they met a danger, he would come to save them again, and more importantly, as Masa had said before, the three were so weak that no one would think they would be able to do anything to Azazel.
"Go back since you are more useful to me that way."
Petting Raynare's chin like a cat, which made her purr and look at him with misty eyes as if begging him to do something naughty to her, Masa smiled and said, "Be useful to me, and I will give you a surprise later."
"Surprised?" 3x
"Yup. Looking forward to it."
"...it's not your wonderful stick, right?"
"...it's something else."
Regardless, the four of them continued to have fun for a while until the three returned to the Grigori nervously, but knowing that Masa would come if there was a danger, they decided to believe in him, or rather, they had no choice to believe in him since if he was the only one that he could rely on, especially after the death of Azazel was related to them!
However, for a man who could even kill the leader of the fallen angels, why couldn't they trust him?
Nevertheless, when the three left, Masa looked in the distance and said, "Come out. Do you have fun to peek at me?"
"—?!"
The figure was startled, never expecting Masa to notice her, but this figure never had any intentions to meet Masa and thought to run away, but unfortunately—
"Mobius World."
The figure was pulled into a loop space as she screamed.
"Let go of me, nyaa!"
"No."
Masa answered as he looked at the young woman before him, thinking that a cat was really a naughty creature.
.
.
.
.
"I am sorry for peeking at you all the time, nyaa! I won't tell anyone of your affair with the fallen angels and your naughty days with them, nyaa! So, can you let go of me, nyaa?"
She had a voluptuous figure and large breasts that appeared so full that they almost spilled out from her loose-fitting black kimono, which she wore on her body in a way that showed her round, white shoulders and long, fleshy thighs that appeared so delicious.
Her face was beautiful with long, black hair, which she tied in a way that showed her slender nape, yet the most unique part of her features would be her hazel-gold eyes with cat-like pupils, pair of black cat ears, and two black tails, which she swayed in a lazy, yet sexy way.
"Do you think I will let go of an SS-Class Stray Devil like you, Kuroka?"
Yes, the one before him was one of the most powerful stray devils in history, Nekomata, Kuroka. At the same time, she was also the older sister of Koneko, the cute white-haired cat in Rias' group.
"Why not, nyaa? You even let go of fallen angels, nyaa? Can you let go of a cute cat like me, nyaa? Or rather, what did you do, nyaa? What is this space, nyaa?!"
Kuroka knew that devils had the technology that allowed them to create a virtual space to hold a Rating Game, but this was different, she thought. Moreover, if it was just such a virtual space, with her magic mastery, it would have been easy for her to escape, but somehow, this space was so confusing and messed up her senses when she tried to use her teleportation magic.
Was this an illusion?
Did she teleport forcefully to another place?
Or was this an imaginary space created by Masa?
Yet, Kuroka knew that this was a troublesome opponent, especially when Masa could control the space, which made her realize that her chance to run away was as good as zero.
If she wanted to escape, then she knew that she could only defeat Masa, but... could she?
"Don't you know that curiosity killed the cat?"
At that moment, Kuroka felt her entire body filled with intense fear, which caused all the parts of her body to tense, and she subconsciously threw a ball of energy blast to Masa.
BOOOOOM!
'I got him!'
Kuroka thought that Masa was hurt by her attack, but she widened her eyes as the ball of energy blast passed through Masa's body, which turned into a mist-like before it returned to normal.
"Illusion?!"
Matoi.
This was the ninjutsu that Masa of Mahouka learned from Kokonoe Yakumo, which allowed him to create a body clone, which was impossible to find by his opponent.
'Well, it isn't like it is omnipotent.'
While this magic made it impossible for anyone to attack him as Masa had tricked their senses, thinking that he was that body clone if his opponents had a wide area of attack, he, who stood on the side of his body clone, hiding, remaining in a shroud, would be attacked.
However, Masa had to say that this ninjutsu, or ancient magic, was great, which made him want to know the "Parade," the modern magic version of Matoi, which had become the advanced version of the "Matoi."
Regardless, Kuroka didn't intend to give up, using her "Senjutsu" and "Ki" to detect Masa's presence and escape from this illusion, but unfortunately, it was all in vain. Masa was in front of her, and her senses told her that the body clone before her was the real Masa instead of a fake!
"What are you, nyaa?! You are a devil, but why are you acting like a ninja, nyaa?!'
Still, if she couldn't find him, she thought of using a wide area attack by creating a poisonous mist, which was her speciality and trademark, and also a trump card, which allowed her to defeat all of her opponents and kept living till now despite her status as the SS Rank Stray Devil!
Only—
Crack!
"—?!"
Crackle!
The space cracked, and black-reddish lightning spread everywhere as a powerful impact brought her down. She was attacked, and her mind was instantly subdued, causing her to cower in fear and even cry.
'What is he?! What is he?! What is he?!'
Kuroka thought that it was quite interesting to peek at three fallen angels, who were caught by the leader of the fallen angels, Azazel, wondering why they were caught, but then she saw someone suddenly defeat this leader of the fallen angels, which made her dumbfounded and surprised.
A strange desire was also born in her heart, but her cautious nature didn't allow her to start a straightforward approach, and she kept watching from the distance as she saw how amazing he was by taking down three bitchy fallen angels, especially Masa's front tail was just too... staggering.
Yet, even if Masa was strong, his ability to detect his surroundings was quite limited, she thought, but it seemed he just toyed with her, waiting for Raynare, Mittlet, and Kalawarna to leave, then met her directly, which made her wanted to cry!
Or, rather, she was already crying!
"D-Don't kill me..."
"Have you joined the Chaos Brigade?"
"Ha?"
As Kuroka showed confusion, Masa felt strange and then asked, "What are you doing here?"
"I was just playing around, nyaa! I am just bored, so I thought of playing a prank on the little sisters of Lucifer and Leviathan, nyaa!"
Kuroka was afraid that her little sister would be targeted, so she lied about why she came to Kuoh Town.
Even though Rias and Sona were the governors of Kuoh City, it didn't mean that they had full control over this city. Many supernatural creatures were living in this place, and even the church was a property owned by heaven. Instead, even if they were a governor, their control over this city was akin to turf, like how a yakuza worked.
So, Kuroka could enter this city as she wished to, especially when Rias and Sona weren't that powerful.
Only, all of a sudden, Masa's body started to transform into his human-beast form, causing him to become even bigger, and he gained Nemean Leon features, especially with his hair that grew into a golden and platinum color that danced wildly.
"..."
Kuroka just stared at Masa for a while, blinking her cute eyes, clearly forgetting her fear as she started to feel a heat that started to capture her entire body, which caused her to squeeze her plump, healthy legs tightly, especially when she saw Masa had become much, much "bigger."
"...wipe your drool."
"Ah, um, sorry, nyaa!"
Kuroka wiped her drool right away, then said, "I changed my mind, nyaa!"
"What do you mean?"
"I won't play with those little sisters of Lucifer and Leviathan anymore, nyaa!"
"Why?"
"They are too boring, nyaa!"
"What are you planning to do, then?"
"Well..."
With her most seductive expression and pose, Kuroka asked sultrily, "Can we make a lot of kitty, nyaa?"
"....."
Masa fell silent as he lowered his gaze to the body of the woman who was almost completely exposed before him.
"By the way, it's my first time, nyaa!"
"It's my first time, too."
"....." Kuroka.
"Ah, w-wait! I-It's really my first time! Ah, oh~!"
Yet, while Kuroka was flustered, she was glad somehow.
.
.
.
.
.
how less"I know that it might be late to say this, but are you okay with me as a devil?"
"...it's really too late, nyaa."
Kuroka had been tossed around so much that she had become a docile, domestic cat that laid on her loved man's chest, as her tail played with his tail affectionately while her other tail played with his front-tail, amazed by its vigor and power.
Still—
"It's okay, nyaa. I only want kitties from you, not anything else, nyaa."
In other words, Kuroka only wanted to get a gene from Masa's sperm.
Nothing else, nothing more.
Well, if possible, she wanted to keep doing it more with him since it felt great~!
It was her first time, but she had to admit that Masa was great~!
Only—
"It hurts!"
Kuroka quickly covered her forehead and complained. "Why did you flick my forehead, nyaa?! It hurts!"
"Don't have children if you are not prepared to give them a complete family."
Kuroka might be okay to have a child and raise her kitty alone since this was probably what she wished for, but the child was different as this kitty between him and her would wish for a complete family.
A father and a mother.
This was something normal, yet somehow, it was hard for someone to have a complete one.
"..."
Kuroka was immediately silent, watching him in a daze, never expecting that Masa was this type of a guy. She had prepared herself to be abandoned by him after all of that as she knew well how evil a devil was and as she had said before, she just wanted to have strong children, so even if she was treated like that, she didn't mind, and she was also used to living as a stray cat, being haunted by others, so... his words made her in a daze for a while.
"You will be a good father, nyaa."
Showing a gentle smile, Kuroka snuggled him closer, then said, "But I am a criminal in your world, nyaa. Do you think you can bring me to your family?"
"Am I so unreliable in your eyes? Just taking care of you is nothing for me."
If Rias could take all criminals as her peerage members, then why couldn't Masa do the same?
"But if you don't trust me, then I won't force you."
Their meeting was short, and even if they had done "everything," and Masa got her virginity, the trust between them wouldn't have been built so easily, especially when Kuroka's misfortune came from a devil.
If Masa wasn't wrong, while Kuroka was pictured as an evil stray devil who killed her master, he knew well that her master was the one who wanted to harm Kuroka and tried to conduct an experiment on her little sister, so to protect her little sister, she killed her master and became SS Class Stray Devil, one of the most powerful Stray Devils in the world.
Kuroka might not agree to accept his invitation to go back with him, considering her past and all.
As Masa had said before, even if Rias had beautified the meaning of being her "servants," in the end, the reincarnated devils were nothing but servants or even slaves.
Rias might love her slaves dearly, but the others were different and treated those slaves like tools, which was why many stray devils existed, such as Kuroka.
Yet unexpectedly, while Masa was worried about her, Kuroka laughed.
"Hahaha... you are so cute, nyaa~!"
"..."
Watching Kuroka laugh happily as she pulled his cheek, Masa just stared at this silly cat in silence.
"Stop looking at me like that, nyaa! Okay, if you are not afraid, then I can go back with you, nyaa! Or rather, even if I want to escape, I can't do it, right? Just do whatever with me, nyaa~!"
Anyway, Kuroka knew that she couldn't defeat Masa no matter what, so she might as well enjoy her time with him and have a lot of kitties~!
"....."
'Now that you mention it.'
Somehow, Masa felt that he was so pure and silly, but then again, for him, who had a power that made Kuroka only succumb, he knew well that she couldn't do anything except go with him.
Instead, if there was a reason why Kuroka thought to leave him, it was because she didn't want to cause him trouble.
Unlike the others, Kuroka was clear that Masa was a young devil, which was different from the vile old devils, so she thought that he might be naive, yet even if he was naive, he was a man, so how could he abandon his woman?
Still, even if Masa brought Kuroka, he knew that no one would stop him, especially when many crises might arise after he took down Issei and killed Azazel.
If the two didn't exist, Masa knew well that the devil might be in danger, especially when many myths would realize the god had passed away.
Yet, at the same time, he also felt that nothing would happen since even if the god existed in the past, it was the enemy of the devil, and this enemy had gone; it didn't matter.
Instead, the one who would be in danger was the heaven side and those who were in the Vatican; as their god was no longer protecting them, they might be ganged up by the devils, the fallen angels, and other myths instead.
"Okay, then, let me make you my peerage members."
"Huh? Is that okay, nyaa?"
"Why not? Anyway, no one will say anything to me."
"...are you Lucifer's illegitimate child or something, nyaa?"
"I am just an heir of one of the noble houses."
"..." Kuroka.
"So, which piece do you want to become? Bishop, knight, or rook?"
"Why not Queen, nyaa? I am quite powerful, you know?!"
As a stray devil, Kuroka was familiar with the Evil Pieces, so of course, she knew which piece was the most powerful, and considering her power, she felt that she suited the role of his queen!
"You are a bit too weak."
"..." Kuroka.
She wanted to complain, but she knew how strong Masa was, so she could only give up. "Okay, get me the knight, nyaa!"
"Knight, are you sure?"
"Yup, nyaa! By the way, I want to learn ninjutsu from you, too, nyaa!"
If it was before, Kuroka might wish to become a bishop, but somehow, she felt a bit resistant to becoming a bishop, considering her past and all. While her specialty might be magic, she wasn't weak in close combat or physical ability, so the knight piece that increased her speed suited her well as a hit-and-run tactic like an assassin was her way of fighting.
At the same time, if she learned a ninjutsu from Masa, too, then she would become more powerful.
"Sure."
Masa took his knight piece and then transformed Kuroka into his knight.
"Hnh~!"
Somehow, Kuroka felt her body was all warm, and a nice sensation made her leak a sweet moan, but Masa was surprised when two bishop pieces came out from her body.
"Oh, those are my bishop pieces, nyaa!"
Still, inwardly, Kuroka felt helpless, realizing how weak she was since one knight piece was enough to transform her into Masa's knight.
Yet, the amount needed to transform one into a peerage member also depended on the power of the owner of the evil piece.
The weaker the master was, the more evil pieces needed to transform others into their peerage members, and the stronger the master was, the fewer evil pieces needed to transform others into their peerage members.
Unlike Kuroka's previous master, who needed two bishop pieces to transform Kuroka, Masa only needed to use one knight piece.
Masa could probably even use one pawn piece to make Kuroka become a member of his peer group. Still holding two bishop pieces in his hands, he thought he'd do a little research on them.
"Do you want to bring them back, nyaa?"
"Yeah."
"Won't it make a problem for you, nyaa?"
"It's fine. My girlfriend is Leviathan."
"..." Kuroka.
