Harem Overlord

'Now that is unexpected.' Kai thought while looking around at his surroundings.

It had been quite some time since he had entered the barrier yet no one had come to investigate him or attack him.

This could only mean that Kai was either walking into a trap or the demon administration was very slow and careless.

After walking for a few minutes, Kai saw a small town in the distance. Yet when he walked into the town, he found out that the entire place was empty.

Even after using his spiritual sense, Kai couldn't find anyone in the entire place. It was as though the town only had ghosts living in it.

After walking out of the town, Kai saw three more places like it but all of them were empty too. The more Kai walked towards the capital, the more stranger the things became.

He sensed that there was no living creature in a very large radius around him however, he sensed a place between himself and the capital.

Normally, Kai wouldn't have paid attention to such things but it felt as though the place was calling out to him. 

So in the end, Kai decided to teleport there. But the place wasn't a village or a town. It was a cemetery.

The entire place had thousands of graves and if one looked closely, many of these graves were only dug a week or so back.

After staring at the graves, Kai started moving towards the center of the cemetery. He was doing this purely based on instinct but when he reached the center of the cemetery, he started recognizing some names.

They were the demons he had met and befriended after he had married Rias. Looking at the graves opened Kai's past on the demon realm.

In the middle of the entire place was a grave with two names.

"They even made me and Rias a grave," Kai muttered with a small sad smile when he read his name and Rias's name written together on the grave.

It was an honorary grave since nobody had ever seen Kai or Rias's dead body. But Kai had great respect for the person who created his grave.

After staring at it for a few seconds, Kai decided to move on. But he went ahead and touched the gravestone before leaving.

But as soon as his hand came in contact with the stone, it started shining. Kai stood there with an interested expression on his face as the gravestone moved aside to show some stairs going underground.

'Looks like even a gravestone with my name on it is not an ordinary object.' Kai thought with a sigh as he then walked towards the stairs.

As he started going down, the stairs started to broaden. After reaching the last stair, he saw a wooden door jammed shut.

The wooden door however had a formation on it which would prevent anyone from opening it unless the right person dripped his blood on the door.

And since Kai had his name on the gravestone, he could already tell that the door only required his blood.

Kai bit the index finger of his right hand and dripped his blood on the handle of the door. The blood slowly dripped down as the door started opening slightly.

A few minutes later, the entire door opened up as Kai stared inside. Beyond the doors was a small room. The room didn't look like it had anything special but Kai still moved inside it.

The moment he stepped inside, the door closed behind his back. He raised his eyebrows at this ut didn't say anything. After moving a little forward, Kai felt cold wind blowing towards the back of the neck.

But he had already experienced this multiple times so he wasn't surprised. Instead, he would have been curious if the cold wind hadn't been there.

'It feels as though I am stuck in a bad novel where the author tried to do a little bit of horror.' Kai thought slowly before the entire room suddenly lit up.

Four bright white balls of light appeared on the four walls in the room and the light directly scorched Kai's face.

The latter just stood there for a few seconds before the light went away. But now, he was surrounded by four people.

"So you are here huh." Kai heard a familiar voice as he turned towards his right to see Rias's cousin standing there.

The other three people were also Rias's relatives and Kai knew all of them really well. But he could tell that the four people weren't really there.

Instead, small pieces of their soul were present in the room. This was something that people in the spiritual soul realm and above could do. But now that Kai saw them with his eyes, he realized that they had been there for a really long time.

"You guys are foolish you know. Why did you leave behind your soul when you had no idea whether I was even alive or not." Kai said while facepalming as he looked at the four souls.

"Well, there is something important that we have to tell you. Otherwise, we wouldn't have done this you know. Do you know how hard it is to live in such a place?" One of them asked as Kai rolled his eyes.

"How would I know that? I never lived in a cemetery you know. Anyways, what was so important that you had to leave behind pieces of your soul?"

"That is…" One of them started but was suddenly quietened by the others.

"Did you forget? This place is not safe enough to tell him about it." The oldest of them replied which made Kai even more curious. 

"You know, a cemetery might be one of the safest places you can find in the demon realm." 

"Not if the entire place is infested with greed." One of them muttered and suddenly realized that he had made a mistake.

"Did you just say greed?"
