Harem Overlord

The darkness was running through the realms while trying to search for one that still had his body around it.

But Kosma had been quick in her job and had removed all of the clouds from almost all of the realms. The only remaining realm was the spirit realm where the elemental rulers were.

Since the place was divided into numerous sections, Kosma had to personally enter all of them and remove the parts of darkness. But before she could remove it from Levina and Mariel's domain, the Darkness appeared there.

"You look… exhausted." Kosma looked surprised as she the darkness's bloodshot eyes.

He was eyeing the blue spirit realm behind her with a desperate look as though it was his last chance.

Kai also appeared there moments later as he had gone to all of the realms the darkness had been roaming around.

But now, it was the end for him.

"Give up man. Your fate was sealed the moment you made the deal with me back then. You should have made me forget about it so that I couldn't plan anything about it." Kai said with a small smile as the darkness turned to stare back at him.

"But I did that by leaving a piece of me inside you and using it to make sure that you never remembered everything until and unless I personally contacted you."

"That did happen however, Kosma here helped me by sealing that little piece of you inside me. Because of that, I remembered everything and managed to continue with the plan I had made long ago." Kai replied with a smile as Kosma sighed.

"You could have told this to in the beginning but I guess the plan might not have worked then." She then looked at Kai to see him nodding.

"I knew that you would be looking at me and darkness talk in the special realm however, we could look back too. So I had to make sure that he believed that you never knew what I had planned."

The darkness listened to this with a doomed expression on his face when in reality, he was summoning all the power from the spirit realm.

Kai also knew this but he didn't do anything about it. At least not on the front.

He had silently unsealed the piece of darkness inside him and was using it to suck all the power that the man was gaining in front of him.

That was the ultimate way of using an opponent's power against themselves.

'Can't believe I managed to connect everything till this moment. If it didn't connect, it would have probably ended up in a disaster.' Kai sighed as a few minutes later, the darkness suddenly turned back.

"You…" He began to say something but trailed off when he felt a familiar energy inside Kai's body. It was the same energy and power he had been using ever since he was born.

"But now, I have more power than you which means that…" Kai didn't speak ahead and smiled as he lifted his right hand and clenched it.

All of a sudden, the shackles around the darkness's hands expanded into chains and covered his entire body.

Kosma's eyes widened when she sensed the powers of numerous immortal beings inside the chains.

"I had been gathering the powers of many people this entire time and couldn't unleash my real powers in case these vanished. But now that you are in front of me, it's showtime." After finishing his words, Kai closed his eyes and started focusing.

His body suddenly started glowing like a supernova which was bright enough to blind Kosma for a few seconds.

Though even after regaining her vision, she was having a hard time looking at Kai who was shining bright enough to put stars to shame.

'I wonder if this is the moment where the thing written in my death book happens.' Kai wondered with a small smile as he moved towards the darkness and pulled him towards himself.

The changed primordial being looked at Kai with a terrified look. The latter smiled as he touched the darkness's forehead with his index finger.

"I would have left you sealed in End's mansion but if she could be freed, you might be too." He muttered before whispering some words that no one could hear.

But the next moment, the darkness's body suddenly exploded into nothingness. The entire thing was so sudden, that Kosma had no idea what even happened to the darkness.

"What did you do?" She asked Kai with a slightly open jaw as the latter smiled.

"Let's just say that the darkness does not taste delicious." He said with a wink as Kosma looked confused.

She wanted to ask Kai more about this but before she could do that, she remembered Kai's death book.

[ Time, please check whether his death book, is still lying open? ] Kosma asked Time who was alongside End, Space, and Death.

End had brought Kai's death book alongside herself but when she went to look for it, she found nothing.

"It… vanished." She replied with a shocked look as Time and Space immediately looked at Death who took a deep breath.

"The one time a death book vanishes is if a person died." He said in a calm voice as he asked Kosma whether Kai was still standing in front of her.

[ Yes he is and no, it's not someone impersonating him or anything. It's the real one. ]

[ Then that means that somehow, he managed to cheat death too. ] Azrael replied to everyone as all of them released sighs of relief.

But what they didn't know was that Kai could listen to their conversation since currently, he had the powers of every single deity in the world.

He was currently looking at the spirit realm with a sad expression as he wondered how the elemental rulers would react to the message he left for each of them.

He then wondered how every single one of the women he loved would react to the messages he left for them.

But sadly, he would not be there to see their reactions.
