Harem Overlord

"But what about those who died?" Nezuko suddenly asked as the atmosphere turned gloomy.

Without Kai, they couldn't revive those who had died but he was fighting Azazel and they didn't know when he would return.

As far as they knew, Kai could only revive someone who hadn't been dead for long so if he didn't return in a few more minutes, those people will remain dead.

"I don't think you need to worry about them." Sahara whispered so lowly that they could barely hear her.

"That damn kid like adult. I will probably be knocked out for a week or two after doing this but since only I can do this, I don't have a choice." Sahara sighed as she bit her finger.

Black drops of blood dropped on the ground as people started to appear around them. Within minutes, every single person from the army was standing around the group.

Sahara grinned at the others before she fell unconscious for the second time and this time, she would be unconscious for a long time.

The army was still afraid of what had happened and some of them were scrambling around to pick up some weapons to fight again.

But thankfully, the group somehow managed to calm them down by saying that Kai was fighting Azazel and that he would win.

But while doing that, all of them were wondering where he was since no lightning struck the continent and no auras were released.

It was as though Kai and Azazel had simply vanished. By thinking that they had vanished, the group somehow controlled themselves from thinking about the worst. But the question still lingered in their minds.

Was Kai still alive?

But whole thinking that, a meteor shower suddenly took place as hundreds of stars fell. As everyone was watching the shower no one was paying attention to Sahara.

"Wrath." She somehow muttered while being unconscious and darkness surrounded her whole body.

***

As soon as Kai saw Azazel move, he teleported behind him. He grabbed him by the neck of his dress and teleported away.

"Ooooo, The Eastern Continent. Since Sahara killed most of the population, this continent is empty and a perfect place for our fight." Azazel cackled as Kai frowned. His eyes were now back to normal but his frown certainly wasn't.

After all, Azazel had a bad habit of stating the obvious. Maybe it was because he loved to annoy his opponents and see their reactions while he did it.

But that was just a theory created by Kai, only Azazel knew the reason behind his own actions and no matter how many millenniums Kai spent figuring this guy out, he would still fail to understand him.

"Anyways, how did you know that Sahara destroyed most of the continent?" Kai asked as he planned to delay the fight as long as possible to plan some tricks.

"I know everything that happens on this realm. When I first got hold of a vessel on the demon realm, you and that demon empress Rias sealed me back but I had managed to create a small crack on my prison from the outside. As time flew by, the crack remained there and grew wider thus giving me the opportunity to travel here and trick a foolish human.

After that, I waited for a year before suddenly, a comet fell that the realm. And guess how surprised I was when I found out that the comet was you. I had spent an entire year crafting plans to take over the content and I even created those space gates to make it easier for myself. But seeing you, I forgot about my plans to rule this realm and instead planned to fight you. After all, I was the one who destroyed some of those space gates to give you a clue." Azazel praised himself as he looked at Kai.

"And you still won't give me any expression. Guess I will have to do something extreme." Azazel sighed and mist started appearing around his body.

Kai knew that he could only fight Azazel since it was the only thing left to do. He closed his eyes and took a deep breath.

Hellbringer appeared in his hand as his eyes turned to demon eyes. They traded a look and attacked each other.

The mist moved with Azazel as though it was a part of his body. The mist then traveled towards Kai who cut through it with Hellbringer. 

"The Seven Deadly Sins." He mumbled under his breath as the sword started to glow. The only way he could win without using the extreme method was if he used his most powerful moves.

The power of the sins varied depending on the situation. The Sin of greed for example would take every ounce of Greed present near the user and convert it into a copy of Hellbringer that would be as strong as the individual. 

But since Kai was on an abandoned continent, he had could only use sins that require the user's powers instead of his or her surroundings. 

And since he wanted to defeat Azazel, there was one sin that far outshine the others in matters of annihilation.

"Sin of Wrath." Kai said as Azazel suddenly stopped.

He felt a sense of danger as he stared at the sky and his eyes widened. It looked as though the stars were falling.

White beams of light fell through the sky and entered Hellbringer one by one. The sword gleamed with all that power as Kai's eyes darkened even further.

He swung the sword with all his power as his dark beams of light shot out of Hellbringer and his wrath was brought down on Azazel.

However, Azazel just laughed as his wings appeared in front of him. His wings extended even further as they collided with the beams of light.

To Kai's surprise, Azazel's wings started absorbing the energy produced by the dark beams of light as they vanished.

"Did you seriously expect it to work?" Azazel asked as he raised his eyebrows.

"Since you are in the body of a human, I thought that it would have worked." Kai replied and Hellbringer vanished as his eyes returned to normal.

"Are you giving up?" Azazel asked as he frowned. As much as he would like Kai to break down, it wasn't fun if he didn't do it himself.

Kai didn't say anything as his angel wings burst from his behind along with his angel eyes. For the first time, Azazel's eyes widened in real shock as he saw Kai's angelic form. He felt something inside him burning up as he looked at those wings.

"You were put under a curse by the Archangels that made sure that whenever you saw an angel, your soul would start burning. After all, you indirectly slaughtered half of the angel realm by manipulating younger angels while siding with demons." Kai said with a quick curl of his lips.

With a blinding flash of light, the white sword he used to fight Hellbringer appeared in his hand. Azazel's face was a mixture of anger and disbelief as Kai flexed the sword in his hand.

"Excalibur, also known as the heroes sword, ray of light, the sword of hope, etc. This is the strongest weapon of the angels made to counter Hellbringer and the sins. It can give the wielder the power of the Archangels and just like the demon ruler selection, the Supreme deity is also chosen by this sword. And according to the Archangels themselves, Excalibur was the sword that corrupted you.

After all, you were one of the seraphim before you got corrupted. According to them, the sword will corrupt anyone who it finds unworthy but no one knows why it does that. So you, Azazel, a seraph decided to hold the sword and become the Supreme deity but it rejected you and instead corrupted you. So how does it feel knowing that your opponent can use something that you couldn't use." Kai said as he pointed Excalibur towards Azazel.

He snapped.

Something inside Azazel changed as he roared and launched himself at Kai. But that was what Kai had thought would happen as he teleported away.

Trails of blue light were left behind as he tightly gripped Excalibur. Yellow bursts of light launched from the tip of the sword and attacked Azazel.

He was not able to dodge them and growled as they stuck to his body. Kai suddenly teleported in front of him and placed Excalibur over Azazel's heart.

"Soul break." Kai said as Azazel's eyes turned white. His body suddenly went limp and Kai grabbed his throat to keep him from falling.

Azazel suddenly screamed in pain as golden tendrils shot out from his eyes and covered his entire body.

He started burning as the tendrils destroyed him into tiny little pieces that vanished as soon as Kai snapped his fingers.

But before Kai could sigh in relief, he felt a sudden glare as he turned around to see Azazel's real body hovering in the air.

"You bastard." Azazel said, his sadistic sens would humor gone as he launched himself at Kai with determination to tear him apart.
