My name is Renze. I am a planet hunter, searching for planets suitable for pioneering and development.

However, due to a spaceship malfunction, I crash-landed on an uncharted planet. I ended up living a survival life with Eleksia YM10, my Mate Gear, who also serves as the spaceship's core intelligence.

That being said, with my Mate Gear, Eleksia YM10, she takes care of all my personal needs perfectly, and even secures food for me, so, surprisingly, I'm leading a comfortable life.

What's more, this planet seems to have once had humans. For whatever reason, whether they are the remnants of that past or something else, numerous remarkably human-like creatures inhabit it.

If this is a planet with intelligent life forms other than Earthlings, and moreover, human-like ones, it would be a monumental discovery for history. However, with no way of returning home, I decided to spend the rest of my life enjoying myself by befriending the creatures there.

From the Author: Since I had the chance, I thought about writing a stereotypical 'isekai' story (being transported to another world), but it just didn't quite click. So, I decided to go with the setup of crash-landing and being stranded on an uncharted planet with a Mate Gear.

The reason I brought a Mate Gear along is because I have no intention of emphasizing the survival elements. Also, she's my 'wife number one,' so to speak.

In short, I just wanted to see what would happen if I wrote a straightforward, no-frills isekai harem story myself.

Incidentally, while the serialization has become quite long, the story starring Renze as the protagonist is temporarily concluded up to Chapter 5, titled 'Happiness'. Anything beyond that could be correctly understood as '<another story from Renze's perspective>'.
