The harem would not be too large(I'm not sure how many but probably just 4-5 main and few other here and there). All the girls would be getting their time and story.2. The story is starting when the MC is in the middle of his growth stage and not at the very beginning. But his beginning will be mentioned in the story in some form.3. I don't think I need to mention this, but obviously it will not have any NTR, rape or that kind of stuff. It is actually quite a wholesome story focusing mainly on adventure, action and bit of romance and slice of life.

In the year 2050, a colossal spaceship suddenly appeared above Earth.

Governments worldwide panicked as they saw the vast spaceship that had just teleported near Earth. Before they could even understand the situation, one humanoid alien emerged.

“Humans, I am your ancestor.”

“We distributed our life code with an atmosphere-changing module device to many universes and galaxies, hoping to recover our numbers after the war.”

“I will now awaken the earth's mana core and install a dimensional dungeon system, which will open many dungeons around the earth.”

“I'm also connecting Earth with a System.”

“This will help you awaken faster and get strong enough to survive in our universe. Gaia(system) will explain to you other important things,” He finished and then disappeared with the spaceship as he was never present there.

[Hello Humans, I am Gaia I will help you all to awaken and become strong]

..................................

After 300 years, Earth is full of mana and many powerful beasts that roam all around the world.

All people awaken their “Book of Contracts” when they are 10 years old by clearing the beginner's trial, but Rishi failed twice to clear his trial and only has one chance left.

Which he has not used due to his fear of failing.

Follow Rishi on his quest to overcome his fears and become “The Greatest Beast Tamer of Earth.”

Dear readers! Without any ads, maybe you will prefer .

I was stuck in a dungeon explosion while working so hard that I actually died.

But when I opened my eyes, I was back to the time of 3 years ago!

Well, I will live differently in this life. Salary is goodbye to s*ave life. I quit immediately and set up a cafe in the store my grandmother left behind.

There are no customers because she is right in front of a dungeon, but it doesn’t matter. All I want is to work two days and play five days. But.

Also, the attractive regular customer who keeps bothering me is somehow unusual.

It doesn’t feel good. Isn’t it like the story of the main character of the RPG, who was just trying to run an errand, and ends up fighting the devil after getting caught up in something annoying?

Yes, I will not. I can not. I have no intention of playing more than the role of a novice innkeeper.”
