Capital of the Dead

Capital of the Dead (死者の都, Shisha no Miyako) is the place where people who have passed on live.

Background
The rumor about the area has led travelers and rich people to settle, forming the village which is located at the entrance of the Capital of the Dead. An living individual cannot go to the place if they just desire to. However, a common saying, "A priceless memory shared with the deceased will open the path to the capital," implies that a person who shares a precious memory with a deceased person can enter the place without dying.

Trivia
