Chapter 1: The Avengers

A private house in Kuou Town is shrouded in a layer of invisible magic power, which can prevent that everything that happens inside is not perceived by others.

"No, don't kill me, Lady Devil, please spare my life."

A middle-aged man covered in blood was kneeling in the living room, his face was extremely distorted by fear, there were many wounds on his body, and the blood kept gushing out, but he had no time to take care of his wounds, he just knelt blindly. On the ground, he begged the woman in front of him for mercy.

Standing in front of the man was a beautiful woman with long black hair. She has fair skin, a good face, and a slender figure. The dark blue tights show her uneven body to the fullest. The six black bat-like wings spread out on the back of the woman are even more impressive.

A mysterious and seductive woman.

"Well, what should I do?"

The woman tapped her chin with her fingers with some embarrassment, revealing a hint of cuteness in her maturity.

"The master ordered me to kill everyone who signed a contract with the Gremory family. If I don't kill you, the master will be unhappy."

"No, don't kill me, as long as you don't kill me, I will agree to any conditions!"

"Well, if you agree to draw a contract with the evil Gremory family, I can make something special for you."

These words were like sounds of nature, the man was overjoyed, originally he signed the contract with the devil out of curiosity, and he only summoned a devil once, and what he summoned was a cute loli named Toujo Koneko. and only took a few photos.

He didn't expect to be found by the woman in front of him tonight, she came through the door, used all kinds of magical powers that you have only seen in fantasy movies to beat him down and end like this now.

"As long as you cancel the contract with the Gremory family, you can live."

The man nodded fiercely and shouted:

"Okay, okay, I just ask you to let me go, I was also deceived by them to sign this dammed contract. Yes, as long as you let me go, I will immediately terminate the contract with them."

"Well, well then, for the sake of your sincerity, I will..."

The man's eyes lit up immediately, he kowtowed fiercely and said loudly:

"Thank you, thank you Lady Devil, thank you for not killing me."

The woman smiled and said:

"For the sake of your sincerity, I'll give you a quick ending, so as not to cause you too much pain."

Before the man could react, the light blade swept towards his neck, and just like that, his head and body were separated forever.

The woman looked at the head rolling on the ground, the face had an expression of disbelief, clasped her hands together, tilted her head cutely, and said with a smile:

"Well, I said it was going to be quick, clean and tidy, you shouldn't have felt any pain. Ah, ah, I am really kind, maybe I should not be a devil, but an angel."

"He he, you're really evil, just kill it, why give people hope for no reason?"

While talking, a man walked up to the woman, put his arms around her shoulders, and the woman leaned her head on the man said coquettishly on his shoulder.

"It's just for fun. Who said this guy was a contractor under Rias Gremory's group? I hate those who has something to do with the Gremory family. By the way, master, I know you kill the Gremory family's contractors, when will you attack the Gremory family? It should be easy to deal with those guys with your strength. What are you waiting for?"

The man pinched the woman's towering breasts, and the woman let out a comfortable moan.

"Revenge is interesting only if you do it little by little. Isn't it more interesting to play with those mice in your hands? This mission is a test I specially prepared for you. Besides, it's better to rely on your own hands to get revenge. Isn't that the most pleasant way?"

After the man finished speaking, he hugged the woman horizontally, and the woman let out a burst of giggles. As soon as the woman raised her foot and took a step, the two of them disappeared from the living room.

There is an endless land in a special space independent of this world. There are all kinds of exotic flowers and plants growing on the land. In the distance, there are mountains, plains and oceans. There are countless precious metals there. And precious mineral deposits, there are also various rare birds and animals living here, take whatever you want, anything, it can be sold at sky-high prices in the outside world.

There is a magnificent palace in this space, and this is the only house here. On the big bed in a luxurious bedroom in the palace, the man and woman just now are lying naked on it, and the man is holding the woman in his arms by her shoulder's, the woman's face was a little flushed, and she was panting slightly, obviously just after a tumultuous storm.

"Master, what should we do next, continue to kill the Gremory family's contractors?"

"Well, but you can leave some openings for them appropriately, the provocation is almost enough, It is too pitiful to keep them passive all the time. It is also necessary to give them some bait properly. Credit won't last long and we should close the line. "

The woman smiled softly and said softly

"Master, it's done, those two bitches, Rias Gremory and Himejima Akeno, I will defeat them, I must take revenge on the two of them and let them taste what it feels like to be trampled underfoot!"

Before the man could speak, the bedroom door was pushed open, and a female voice sounded immediately

"That's not okay, Viser, Rias Gremory is my prey, and Master has already agreed that with mine."

The owner of the voice is a woman who is as beautiful as Viser. The woman also has black hair, and a pair of deep purple eyes are very charming. The woman is wearing an extremely revealing tights, just like a S&M suit, with a large area of ​​skin exposed. The huge breasts seemed to be about to break free from the shackles of the clothes. Behind her were two women, one was a tall, blue-haired beauty with big breasts in a sexy red suit, and the other was a petite blonde gothic lolita.

Viser snorted coldly, sat up and said to the woman in front of her:

"Humph, Raynare, don't try, you three have just digested the power that the master bestowed on you, you dare to challenge me, dare to try to take away my prey from me? Don't think too much of yourself"

"Hehe, Viser, you are the one, you don't take us seriously because you are the first servant of the master, but we are not idle these days."

I saw a huge spiritual energy burst out from the bodies of the three of them.

"Oh, not bad, the three of you have reached this level in a few days. Raynare has already reached the level of a high-ranked fallen angel, and Kalawarner and Mittelt have also reached the level of a middle-ranked fallen angel.

Yes, if we apply the standards of devils, you are already able to compete with high-level devils and intermediate-level devils. You are the worthy women I have chosen. What should I do? Viser, if there is only Raynare, maybe she won't be able to oppose you, but if the three fight together..."

"Humph, just right, it's time to stand up, let you see who the master's number one subordinate is!"

After saying that, Viser jumped up from the bed, and the clothes appeared on his body out of thin air in an instant, and six black wings spread out behind him, rushing towards the three of them with lightning speed, and the four smashed through the floor-to-ceiling glass of the bedroom.

Raynare instantly spread out the six black wings behind her, and the other two also spread out four black wings, and the three began to besiege Viser.

The man looked out the window and saw the fierce battle among the four people in the air. He shook his head helplessly, got off the bed and walked to the mirror, looking at his body in the mirror.

"I'm the strongest dragon god, inside Hyodou Issei's body, the strongest body, that possesses the power of both Sekiryuutei and Hakuryuou, as well as Infinity Dragon God, Great Red and Trihexa, and finally fully grasped this power, my revenge on this world is finally about to begin, now that this has happened, things cannot be changed, so I will use this strongest body to create a new world."

Hyoudou Issei closed his eyes and recalled what happened when he first came to this world.

"You, who are you? Why do you look exactly like me?"

Issei stared in shock at another figure that looked exactly like himself.

"Hyoudou Issei" said with a smile,

"Who am I? I am Hyoudou Issei."

After saying that, a red gauntlet appeared on the left hand of "Hyoudou Issei".

"How is it possible? How do you also have the Sekiryuutei's gauntlet?!"

Although Issei was shocked, he didn't keep still because of it. He quickly called out his own Sekiryuutei Gauntlet, rushed towards the other self.

"No matter who you are, I will find out after defeating you!"

The "Hyoudou Issei" on the opposite side shook his head with a smirk, just when Issei was about to hit him, he disappeared of the place in an instant. Surprising Issei, he looked for the enemy, an arm suddenly strangled his neck from behind, and the strength made him suffocate, he couldn't resist. A light blade pierced Issei's chest from behind in an instant, a mouthful of blood spurted out from Issei's mouth, his pupils shrank instantly.

"Hyoudou Issei" said in his ear:

"Don't worry, you can die with peace of mind, I will live on your behalf, and your artifact will come to accept it, and I will use it in a more appropriate way."

"Hyoudou Issei" let go of the arm that strangled Issei's neck, and put his hand on the red dragon on Issei's left hand, Sekiryuutei's gauntlet slowly turned into red light particles and was sucked into the body of "Hyoudou Issei".

"Hyoudou Issei" threw away Issei's body, his right hand began to glow, and slowly emerged another Sekiryuutei's gauntlet came out, and now his hands are covered by the gauntlet, and at this time there was a burst of restlessness from the gauntlet on the right hand.

"Hmph, is Sekiryuutei's consciousness resisting me? It's so boring."

Immediately, he wiped the gauntlet on the right with his left hand, and the restlessness gradually disappeared, because Draig's consciousness has been killed.

A sound brought Hyoudou Issei back from memory to reality, and he saw Raynare and Viser flying back to the bedroom in a bit of a panic, with Kalawarner and Mittelt on their shoulders, and they were already unconscious.

"How about it, what's the result? Have you decided on the distribution of the prey?" Raynare said and panted.

"Hmph, I have to admit, you are still stronger, but it's only because you got the power earlier than me. It's just the strength, I'll give it to you this time. " Viser laughed.

"Hehe, you're not bad either. You've reached your current level in a short period of time. I'll give you the hunting rights of Rias Gremory. I just need that Himejima Akeno."

----------------------------------------------------------------------------------------------------------

"Damn it! It's the fourth time this week! Who is killing our clients? * Dammit. "

In the activity room of the Occult Research Club in the old school building of Kuou Academy, the president of the Occult Research Club, a beautiful red haired girl, Rias Gremory, slapped the table angrily.

"Akeno, what's the result of the investigation? Do you have any clues?"

Rias asked the black-haired beautiful girl beside her, the Vice President Akeno Himejima.

"President, according to our investigation, the bodies of the victims, all had remains of magic power, it is certain that these people should have been killed by people with magic power, so we locked the suspect as a stray devil, but we haven't received any reports recently. The news about stray devils, and the fact that every time the person who dies is one of our contractors, means that the murderer should be targeting us, so we have arranged magical perception for all those who signed the contract with us, if they encounter danger, we should be able to detect any attack, but the strange thing is that we have never noticed the murderer committing the crime, I am afraid that the murderer has the ability to block our investigation."

Rias sighed.

"When the homicide was reported on the news at the beginning, I thought it was just an ordinary burglary homicide, and I didn't pay much attention to it. If Asia hadn't happened to come to the crime scene when accepting the commission, We are still in the dark. "

Akeno replied:

"It has never happened before that we broke into the scene of the crime, and the time from when the deceased summoned Asia to when Asia came to the scene was only a few seconds, so it can be seen that the murderer either deliberately aimed at the victim. The instant the victim summons Asia, or he forces the victim to summon Asia, but either way, both mean that the murderer deliberately let us know that his purpose is against us. "

"Yeah, he obviously didn't intend to just hide behind the scenes, but officially declared war on us. What's annoying is that although we have set up a strict surveillance network around our contractors since then, we still can't catch him, and you and I have encountered Asia's situation several times, but we can't perceive each other's position at all. You must know that we are equipped with the most advanced magic weapon in the underworld. Force sensing equipment. "

"Akeno, what happened to the magic power positioning system that I have requested?"

"Yes, it has been approved, and we will be able to configure it for all of our staff immediately. This magic positioning system is a kind of magic formula, which can be directly penetrated into our body, unlike those physical positioning devices. However, if it is disturbed or destroyed, it will not be able to locate. This system can pass through our chess pieces and use similar mind-spirited, directly transmit our location information to the king in the corresponding way. "

"That's good. The murderer is targeting us. He will definitely find a way to attack us in the end. Although it is selfish to say this, I care more about the safety of my peerage than the contractors. If it is really impossible to guarantee the contractor's safety, at least to ensure the safety of the peerage."

"By the way, Akeno, what's going on with the student union? The current incident is a bit out of control, although this incident this time was aimed at us, but at least it was in the same area. It would be bad if Sona was implicated because of us. "

"President, the student union has been recalled by the Sitri family recently, so they are not in the school. The latest investigation report has not yet been notified to them, but according to the time, they should be back in a few days up. "

Rias was taken aback for a moment before realizing it.

"Is that so, I was wondering why I haven't seen Sona and the others recently. This matter has made me burnt out these days, and I have no mood to care about other things. "

"Then I will contact President Sona next."

"No, I'll contact her directly now, anyway, they shouldn't be here at this timeframe is right." After Rias finished speaking, she made a communication magic circle appearing next to her ear, and quickly called her friend.

"Sona, is it convenient for you now? I want to tell you about what happened recently."

Sona Sitri's slightly panting voice came from the communication magic circle.

"Ri…, Rias, yes, what's the matter?"

Listening to Sona's voice, Rias asked strangely

"What's the matter Sona, your voice is a bit strange."

"Ah, no, it's fine, I'm exercising, so I'm short of breath."

"OK."

Rias breathed a sigh of relief, what happened recently made her a little nervous, and she was afraid of the people around her. She told Sona about what happened in Kuou Town recently, and told her to come back as soon as possible after finishing her work there. There is no guarantee that the stray wouldn't also attack Sitri's contractors in the future. After all, if the contractors are killed continuously, the evaluation of the devil family in the underworld will also be affected.

"Ah, I, I know, no, I didn't expect to leave Kuou Town for a few days, and this kind of thing happens. Our work here is about to end, and we will be back soon. Thank you for letting me know, ah..."

Sona's intermittent words came from the magic circle, and he hummed softly.

"You don't need to thank me. In the end, I should apologize, because my negligence caused the incident to get out of control. Please help me, I'm really sorry, speaking of it, Sona, your voice is really a bit weird, take care of your body, exercise is a good thing, but don't ruin your body. "

"I know, I know, thank you for your concern." Immediately the two cut off contact.

On the other side of the communication array, in a study room, Sona Sitri lay naked on a table, with a clear mark of a red dragon head on his back. Issei held Sona's upturned snow-white buttocks with both hands, and his huge avatar kept entering and leaving Sona's wet cave.

"How about it, you sow really know how to make up, do sports? Haha, but it's true, isn't it just doing sports! Do piston movement!"

"Ah, ah, ah, really, really, it's the master, you insisted on having sex while talking on the phone, and Rias almost found out, oh, oh!" Sona moaned on the other side, and generally complained to Issei.

"Hehe, what are you saying? It's exciting to be fucked while on the phone with your friends, don't lie, you know you want to do it yourself!" After finishing speaking, Issei pulled out his weapon and inserted it hard into Sona's asshole.

"Oh! Oh! Oh! Oh! Oh, oh, oh! So sudden, it's an asshole! Okay, it hurts, but it's feels so good! Hey, yes, I've always been prudish, pretending to be so cold that people don't get to close to me, but in fact I've been wanting to try this kind of thing while talking to other people while having sex, it's so exciting!" Sona yelled with a lustful face at the surprise anal sex."

"Haha, look at your usual aloof and indifferent look, but you've been dried out in the end. You look like a horny sow."

Just then there was a knock on the door

"Come in."

Issei spoke, but his lower body didn't stop.

Raynare opened the door and walked in, saying:

"Master, Vritra's sacred gear has been taken out."

"Oh, has it been taken out? How is the host? Is it dead?"

"Yes, it's dead."

"Well, let's bury the body in the garden, and become the nutrient of this land together with the original Issei. As for Vritra's artifact, let's make the best use of it, and transplant it to Viser. It should increase her strength a lot. "
