Omni-Harem God: conquering Worlds and beauties from all over Reality

There are multiple ways to live one's life and still enjoy it the same way.

That was something that Kymani Njeri Marvion believed in and his ideal way of life was to master everything and see the all of the world and what it had to offer. Unfortunately, that could not be achieved as Kymani perished before he could even start.

Having been unable to fulfill his dream of seeing all the world had to show as well as master it all, Kymani was disappointed but not surprised, after all, there was only so much one could see and experience before their time on earth was over.

It was then, while his soul was in the infinite darkness of the Void that he was met with a multidimensional cubic structure that once in contact with him asked.

[What is it that you desire?]

"Desire? Huh?... If I could I would like to see it all, not just the world... I want to see what all of reality has to offer and maybe meet a beauty or two along the way, wouldn't it be nice?... Even better would be if I had one of those super loyal maids you see in anime... Hahaha! I guess that's all I want. Man, I kind of have trash desires, don't I? Hahaha! Whatever I'm already dead anyway." Kymani could help but laugh at his own desires as he let his thoughts out into the void.

[Your desires, have been made achievable.]
