Harem Overlord

"This isn't going to be easy." Kai muttered to himself as he stared at the realm in front of him.

The realm of spirits was truly magnificent since it was a literal transparent blue realm which no one could see unless they knew what they were looking for. But Kai exactly knew what he was looking for but the problem was how he would enter it.

Only spirits could enter the realm and after that, they would have to search for special entrances that would lead them to a particular ruler's realm. Kai was not a spirit so there was no way for him to enter the spirit realm but where there is a will, there is a way.

"Are you guys ready to do this?" Kai asked as he turned to look at the five spirits standing behind him. It hadn't been that long since he had rescued them but all of them had become friends in such a short time.

Their appearance was striking as all of them had hair and eyes the color of their respective element. Kai didn't know why but he had named them. Perhaps it was because he didn't want to call them spirits.

Coming out of his thoughts, he extended his hand towards the first spirit in line. Her name was Misty and she was a water spirit with dripping blue hair and sea-green eyes. Kai didn't understand how her hair were always were but he felt that it would be best that he didn't ask her about it.

He took her hand as she slowly started fading. She vanished as Kai's hair suddenly became wet. Misty had just merged with him to give him half spirit form but even if he was half spirit, the elemental rulers would easily detect his presence on their realm.

So to reduce the chances of this happening, he decided to merge himself with five spirits. For a normal person, this was impossible. But Kai was half-demon and because of that, he was somehow able to handle the power of five spirits inside him.

He extended his hand towards the other spirits as he one by one started to merge with them. Though his appearance didn't change much, he still felt the raging powers of the five spirits inside him.

"Hope everything happens like how I planned." Kai said to himself as he took a deep breath and jumped towards the realm.

He had to buy a very expensive treasure for this inter-realm travel but if everything went according to his plan, it would be worth it. As he neared the blue bubble of a realm, he felt himself travel through a ripple of power.

As he entered it, his descent started to slow down before he completely stopped and hovered in the air. He took a deep breath and his eyes. Normal eyes wouldn't help him see things in the spirit realm as the spirits started to talk with him through their connection.

"Why do you want to open the seal on the spirit of life and death, Kai?" Sera's voice echoed in his mind and the others went silent as they also wanted to hear his answer.

"It's because I feel that what happened to them was unfair. Hardly any people alive know about this so I wasn't able to find what happened to them. But being locked for so many years without any interactions while being conscious the entire time is too much for anyone. Instead, if it being a seal, it's like a curse for them." Kai replied as the spirits were silent.

For some reason, Kai was obsessed with curses and whenever he would hear the word curse, he would drop whether he was doing and pay full attention to the curse-related thing.

The spirits didn't know why he behaved like that but they knew that the only reason he met them was that he had heard of evil scientists who were creating new types of curses by testing them on spirits.

After that, they had also met a woman named Hailis who was under a curse that made her transform into an animal during the night. Kai had helped her in removing her curse and they had fallen in love with each other because of that.

But they knew that Kai had wanted a harem as they had later traveled to the elven realm when a rumor that the daughter of the elven ruler, one of the two elven princess, was under a curse that depleting her spiritual energy.

Kai had healed her too and had spent quite some time with her that the two of them had become a pair. And now, they were on the spirit realm as Kai tried to search for the seal.

After a few minutes of hovering around, his attention snapped towards a particular area of the realm which was blurring a little. As Kai tried to make his way towards the spot, he hit against an invisible barrier and was thrown back.

"Guess we finally found the spot." He said while grinning as he wiped the blood that was dripping from the corners of his mouth.

He stepped back as he bit his finger. Black blood started to drip from his finger as he started drawing symbols with it. The symbols flared to life as he stopped drawing them. They continued to shine as they merged together to reveal even more symbols.

The new symbols looked ancient as Kai's eyes widened. They were more complicated than he had imagined but he could still dismantle them. After all, what was the point of being the number one formation master's disciple if you can't figure a formation?

"What if they are hostile and try to destroy the entire world?" Jade suddenly asked as Kai started recreating the symbols.

"I am sure that soon after their release, the elemental rulers would be here since they would feel the burst of sudden energy. If the spirit of life and death are hostile, we will leave them to face the bigshots while we will run away." Kai explained as he slowly recreated the symbols.

When he was halfway done, he suddenly stopped as he felt a dark aura around him. He suddenly had goosebumps as the aura started to grow before it suddenly vanished and was replaced by a warm aura that made Kai relax. This aura also vanished after a few minutes and everything returned to normal.

He resumed his work and spent weeks on it before the auras returned. But this time, their powers were far greater than the last time. The symbols started to tremble and a ripple of power went across the entire realm.

One by one, the symbols started to crack as they fell apart and crumbled. With a blinding flash of light, all of them were destroyed as two figures appeared in front of him.

Both of them were women. One had silky black hair while the other one had brown hair. The first one had bottomless blackish-blue eyes while the other one had shining ocean blue ones. Two completely opposite auras were radiating from their bodies as they moved forward to look at Kai.

"So you were the one who freed us. You are not a spirit but are merged with five spirits. Hmm, that's interesting. You are clearly not a human so let's see what you are." The brown-haired woman said as she touched her cheek while his jaw dropped.

Her touch was warm. Kai could clearly feel her hand as her eyes widened and she retracted her hand. The other woman looked at the first one with sharp eyes before she stared at Kai with an ice-cold glare which made him step back a little.

"You are half demon and half…" The brown-haired woman began but trailed off as she looked at Kai's face.

"You don't need to worry about that. My name is Aizza and I am the spirit of life" The brown-haired woman introduced herself as she pointed at her sister.

"I am Hela and I am the spirit of death." Hela's voice was as cold as a chilly winter night as she looked away from Kai and examined the place they were standing in.

"My name is Kai." Kai somehow managed to introduce himself as Aizza smiled.

"Thank you Kai for freeing us. We have been imprisoned for thousands of years and we are finally free. We will take this opportunity to explore the world." Aizza said as Kai began to speak but hesitated. Aizza smiled and gestured for him to go on as he took a deep breath.

"Who imprisoned you?" He asked as Aizza's expression darkened.

"Some people known as the creators. Even though I don't want this to happen, there is no avoiding it. They will come for you to Kai. Our time with you is about to come to an end as we have to go someplace else. But we will leave you with one last gift." Aizza said with a sad look as she looked at Hela.

Their eyes started glowing as a crown appeared on their heads. Both the crowns were gray in color and had nine spikes on each crown. Four spikes from each crown detached from it and flew towards Kai's head. The spikes joined together to form an eight spiked crown and it dropped on Kai's head.

"You have our blessings." The two women said together as they vanished and the crown on top of Kai's head also vanished.

"Maybe we should leave now." Kai said to the spirits and they agreed. But before he could move, he heard a voice behind him.

"Where do you think you are going?" A woman with red hair asked Kai as seven figures stood together behind him.

"The elemental rulers." Kai mumbled as the woman grinned at him.

"You are correct." She said and all of them charged at him.
