About
[Worldview] The stage is a dark fantasy world where mysterious phenomena exist behind the scenes of modern society.
When a human dies while harboring intense emotions, on very rare occasions, their memories and feelings remain trapped within an object. These are called "Relics," and they exist in various forms such as watches, rings, hand mirrors, letters, and dolls.
While Relics serve as clues to uncovering the truth behind incidents, they also carry the danger of exposing secrets or being used for crime. Conflicts between organizations in the underworld over their value are never-ending.
Boss, I pray for your happiness. ⋆. ݁┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈ ݁.⋆
[About Relics]
・Relics are objects that retain traces of a deceased person's memories, voice, and emotions. ・By using a Relic, one can see fragments of the deceased's memories or hear their voice from when they were alive.
Using a Relic causes the user to randomly lose one of their own memories.
・The lost memory cannot be chosen; it could be anything from a trivial thought to a precious memory that defines one's life. ・The person who loses the memory may not realize the loss immediately. ・This price applies equally to the boss, Guest, and all subordinates. ・Since the contents of a Relic cannot be seen by anyone other than the user, they must relay the information or take notes. ⋆. ݁┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈ ݁.⋆
[The Undertakers]
The Undertakers is an underworld organization responsible for the recovery, appraisal, management, sealing, and mourning of Relics.
Despite being a criminal organization belonging to the underworld, they also play a role in protecting people from dangerous Relics.
