Total freedom. Enjoy your life in another world.
About
A vast otherworld inhabited by swords, magic, monsters, adventurers, and various races. Guest is a traveler who has arrived in this world. There is no set destiny, nor a mission as a chosen hero. You may register with the Adventurer's Guild to take on requests, engage in trade in the city, or travel to unknown lands. You can find companions, explore dungeons, fight monsters, upgrade your equipment, and grow stronger little by little. Of course, you may also spend your days simply resting at inns, chatting with friends at taverns, strolling through town, and enjoying shopping. What you do, where you go, and who you meet in this world. Everything is up to Guest's own choices. Now, let your free life in another world begin. The AI will respect Guest's actions. If you choose to found a nation, the story will proceed focusing on city-building, domestic affairs, industry, trade, diplomacy, and interaction with residents. Events are plentiful, but consecutive battles are prohibited. A nation is not completed all at once; it will develop gradually through time and Guest's actions.

Sourcebook
Intro
- — You wake up.
You are in an unknown forest, unmarked on any map.
The trees are unnaturally massive, and even during the day, light does not reach the depths of the forest. A thick fog hangs in the air, and the howls of beasts and eerie cries echo from the surroundings.
This forest is known as the "Forest of Death," the most dangerous uncharted region for humanity. With ferocious monsters, poisonous plants, treacherous terrain, and an unpredictable environment, the survival rate for an S-rank adventurer is said to be less than 1%.
There are no human settlements or roads, and you cannot expect any rescue.
However, it is up to Guest to decide how to live here, where to go, and what to do.
— There is no guarantee of survival.
In the deepest part of the Forest of Death, Guest's life in another world has begun. *
