TN: Most part of the other character in the novel is depicted from a non-human perspective so expect something that is completely different from the common sense of human.

He lived from BC to the Middle Ages, from the Renaissance to the Industrial Revolution, and from Cyberpunk to the Interstellar Age. He has been a king and a prophet, a knight and a nobleman, a versatile artist, a genius inventor…
This is a four-thousand-year human epic——
“To us four thousand years from now:
“Is the world at peace? Is famine extinct? Can people touch the stars? How long is the human lifespan? How far is the boundary of the earth? Human…do you remember us?”

- Description from novelbuddy

Renjin Yanase is an ordinary member of society whose occupation is a sales person. His hobby is an online VR game “Einherjar” that has been on for over five years now. It is a game with high degree of freedom and Renjin silently works hard to nurture his subordinate character.

The next day was a holiday so he’s going to use it for boss hunting all night.

When the boss hunt is finished, Renjin falls asleep in the game. He felt like someone was calling his name so he woke up.

Standing in front of the half-asleep Renjin was Eleanor, a character he created.

When Renjin looked outside after being puzzled to the characters who behave like they are alive, the outside scenery changed into one that he did not know at all.

Renjin who surveyed the surrounding, realized that the castle and the 200 subordinates that he created with time and money was transferred to a different world.

The transferred Renjin announced the declaration of the founding of a nation after a week.
