Harem Overlord

"And why do you think that?" Kai asked while raising his eyebrows but judging by their expressions, he could tell that they knew the truth or at least a small part of it.

"We know that she and the other sins are your masters. We know that you will feel weird killing one of them but this needs to be done." The oldest one in the group said as Kai mentally sighed.

Looks like they didn't know the real truth but the fact they knew about the sins being Kai's masters was surprising.

He had no idea why they knew about it but it meant that they didn't know the real thing.

"Then I am guessing that the sin of greed is in that cemetery?" Kai asked as the souls nodded. "I will go and see what I can do."

His answer seemed to satisfy the souls but they still had to wait to find out what would happen.

Kai then teleported back to the cemetery with a small smile on his face. After so much searching around, he finally found one of the sins.

But the question was what she remembered and what he could do now.

"Greed." Just like one of the souls from earlier, Kai said the word greed.

For a few minutes, nothing happened. The cemetery remained the same as before but after a few minutes, everything changed.

Cold wind started to blow over the entire place and the earth started to tremble. A growl resounded throughout the cemetery but Kai stood completely still.

He could feel a familiar aura coming from his surroundings yet he didn't do anything except stand. He had no idea what would happen if he moved since the sin of greed, Elaine, was the top 3 strongest sins.

Her powers were enough to make the most loyal of friends backstab each other but that was not all that she could do. Her combat prowess was better than Kai's and in a one-on-one battle, she could obliterate the foe in less than a second.

But another reason she was called the sin of greed was because of her greed. No matter how much she fought or how many opponents she defeated, Elaine still couldn't sit still.

She was a bit similar to Levina and Sahara but on that regard, she was more powerful than both of them combined. If Kai had to describe Elaine, he would say that she was a retired soldier who could not sit still.

But one thing she had a huge greed for was blood. Blood of the people she killed. At first, Kai had been creeped out by this fact and had decided to maintain his distance from Elaine.

But the better he got to know her, he realized many things. Kai had already known that there were all kinds of people in the world but meeting the sins made him realize that some people would always stay the way they wanted to stay, no matter what a person said.

Elaine had a greed to see the blood of her enemies was because she had been born and raised on a battlefield. So unless she saw the blood of the enemy, she wouldn't believe that he or she was dead. Kai made a mental note to visit Lilith and ask her about Elaine's back story.

But for now, he had to focus on meeting her.

The earth continued to tremble for a few more minutes before it suddenly stopped. The entire place went silent again and nothing happened.

"Greed," Kai said the word again and nothing happened. He tried a few more times but nothing changed.

'Oh great.' He sighed and teleported to the center of the cemetery. He looked at the graveyard with his and Rias's name before going moving forward and touching it.

The graveyard moved to the side and gave way to the underground stairs. He walked down the stairs and soon saw the door.

After unlocking it, Kai stepped inside and saw that the entire room looked brand as new. The earthquake that had cracked the walls looked as though it had come in a dream.

'Either they were lying or there is something that I missed in this room.' Kai thought silently as he started exploring every single inch of the room.

After a few minutes, he found out a very odd thing. The entire room was made from wood, except for the floor.

The floor was made from dirt. If someone made the entire thing from wood, why did they not make the floor with wood?

So to investigate that, Kai called upon Gaia's blessings. He looked at the earth below his feet and placed his right hand on it.

"No way…"

When Kai checked what was under the dirt, he was left shocked. He double-checked it to make sure that he wasn't dreaming but he knew that it was real.

There was an entire city under the cemetery and it had tons of people. And the people weren't just demons. Kai could sense that there were elves, half-beasts, humans, and…

"Angels." Kai was left speechless when he sensed that a few angels were living underground and that too alongside demons.

He immediately stood up and manipulated the ground to make space for him to go underneath it.

While he was moving underneath the earth, Kai wondered what kind of city would it be. Who could have created such a place and how were people from so many different places living together at once.

That too in the demon realm.

But he knew that the answer to this question lied in the city and that was the only way he could confirm anything.

After ten minutes, Kai suddenly felt the land below his feet vanish as he suddenly hung in the air.

'Was that a teleportation formation?' He looked up to see that there was a bright blue sky above him.

This meant that he was not underground and had been teleported to a new location.
