Harem Overlord

"How did you feel to meet a family member?" Sahara asked Kai the moment they came back.

Much to their surprise, no armies were visible anywhere. This meant that the people were still gaining information or they were just hiding and waiting to attack at the right moment.

But before that could happen, Kai and Sahara vanished.

He teleported them to a place on the demon realm which was very dear to him. It was the place he and Rias and fought Azrael together for the first time and had defeated him.

After his defeat, the place had turned into a barren field but the two of them had worked together and converted the place into their secret place.

Kai had later on put a special concealing formation on the entire place to make sure that no one could enter it and disturb the two of them.

Though he had to let Rias's father enter the place. Her father cared for his daughter's well being more than his life so he wanted to see what Kai was doing with her in private.

Though he and Rias had never done anything like that while being in their special place. They had just held hands and sat there while talking about their daily lives.

It was almost similar to what normal people did except that their discussions were anything but normal. After that, the two of them had slowly started getting closer.

It was as though two teenagers were in love, well except the extra drama that came with it.

After they had grown closer, her father had agreed to Rias marrying Kai and he had been then crowned as the demon emperor. Though he had no idea what was going to happen later on.

But shockingly, the demon empire had the least number of political schemes and drama that Kai had ever seen.

So after his marriage, he had mostly lived a peaceful life but that was until he had to leave. Being a harem overlord meant that he could never stay at one place with just one of his women.

However, this didn't meant that Kai couldn't do anything about it. He visited Rias almost every day in a week unless there were some circumstances because of which he couldn't meet her.

After many years of spending their time in this way, Rias suddenly wanted to journey together with Kai. So the of them then started moving together.

Though there were times when Rias would have to return to the demon realm to manage some affairs and times where Kai couldn't take her to certain places because of restrictions.

But now that he was looking at their special place after so long, he felt all of his time spent with her coming back to his mind. He was extremely refreshed by this feeling.

"Now that we are on the demon real, we will begin our explorations during night time. I would be as strong as a golden divinity realm cultivator during that time, thanks to Sierra's crown. But we won't do anything before that time." Kai explained to Sahara as she nodded.

"By the way, do you know who I am?" He asked with a grin as Sahara rolled her eyes.

"Your name is Kai and you are a very annoying fellow."

"Now I know how you truly think about me." Kai replied as the two of them grinned at each other.

But an ancient sounding laughter made them stop smiling.

'How can someone enter this place? Has my formation become weaker over the years? No, I checked the formation the moment I entered this place.' Kai thought with narrowed eyes as he saw a man suddenly landing on the ground.

"I see that you haven't changed despite so many years. And you still have a beauty traveling with you." The old man, who Chen had called his master, spoke after alnding on the ground.

"Do I know you?" Kai asked while frowning as he tried to remember if he ever knew a really old man with a beard as long as his body.

But unfortunately, he could only remember people who he killed with the same appearance.

"Maybe I should have changed my look before. Well, time to stop using this disguise." The old man said with a chuckle as he closed his eyes and his entire body changed.

Kai's mouth opened slightly as he realized that the old man had been using an illusion or rather, a transformation technique that had changed every little detail of his body.

And he had managed to do that while fooling Kai.

'There is only one person who I knew with these abilities. And he was one of the few people who could fool me with an illusion or transformation technique.' Kai thought with the sigh as he looked at the man's new appearance.

Short brown hair with full red eyes, the man was none other than Rias's father.

"I don't think that's the right look you should give to your father-in-law. But I gave mine the same look so who am I to judge?" The man said with a grin as he moved forward and hugged Kai.

The latter was still registering that his father-in-law was alive and kicking that he couldn't even push him back.

His father in law was named as Kin, a very normal sounding name. But you shouldn't judge anyone by their name because they could be completely different from your imagination.

"Can you please stop hugging me or I might throw you back." Kai said in a threatening voice as Kin coughed a little and stepped back.

"Now I know how my father-in-law felt when I talked to him like that."

"Then you should know to not do these things. And how the hell are you at the golden divinity realm?! Last I knew, you were at the semi-divinity realm."

"Many things have changed after you and Rias died or whatever happened to you both. The demon realm is no longer the place you remembered it to be."
