This is a different world, a world of swords and magic, with elves, dwarves, Warcraft, humans, dragons, orcs, monsters, gods... And other different races, each developing different forces of different sizes, living together here, and staging wars for hegemony in troubled times.
In the long years of chaos, the human race, tired of the endless battles, united, carved a huge magic circle on the heart of the world, summoned brave men from other worlds, and jointly ended this war.
Since then, a group of people from different worlds have been summoned here every January, April, July, and November. The summoned people have different cultures, beliefs, and languages. They are collectively called "travelers" and work with the indigenous people to maintain world peace.
It is said that the time-travelers of previous generations summed up five iron rules:
1. The time traveler comes to this world through reincarnation after death.
2. The age at which the time traveler is reincarnated and revived is a random period during his lifetime.
3. Travelers currently have no way to return to their original world.
4. People who have traveled through the same world will most likely appear in the same area.
5. There are no language barriers in this world.
The 24-year-old Shimura Shinpachi looks exactly like Qingou Munakata Reiji. He habitually pushes his eyes, puts down the documents in his hand and looks at the person opposite.
"Do you understand the above, Yin Sang?"
"Hey, hey—!??"
Motto: Keep smiling in the face of ups and downs in life
