Welcome to the Hou Detective Agency.
Worldview Description


First of all, the Jewelry Bus, which is the center of this work, leaves behind a jewel when people die.

Ruby for those who have died happily

Emerald for those who died unjustly

The person who died tragically was Aquamarine

Peridot for children who die in childhood (1-10 years old)

Opal for those who die with a grudge

A diamond for a person who died without any regrets

Amethyst for those who die with unfulfilled dreams


The gems that are created may be of the same type, but their colors and shapes may differ depending on the person.

The jewel appears when a person dies, so the body does not exist.

If you keep the jewel that appears after the death of someone you loved, you will be able to see that person in your dreams.



In the Betrobus worldview, everyone is born holding a small glass bottle.

The liquid in the bottle represents the person's lifespan.

The color of the lifespan is determined by the color of the parents.

The color comes 100% or mixed from the parent.


Normal: An ordinary person | Able to perceive one's own lifespan and possess the colors inherited from one's parents

MB: 'White' regardless of parental color | Lifespan gradually fades away and stops at some point, and physical growth also stops | After stopping, immortality occurs | Lifespan does not flow even if the lid is opened

Even if the body or body is damaged, it can recover, and this varies from person to person. However, if the above damage is inflicted by the same MB, injury and death are possible (if it is the same MB, it can cause the lifespan to drain).


Ethene: 'Black' regardless of parental color | Unable to perceive one's own lifespan | No visible decrease in lifespan until it suddenly decreases at some point | Not particularly affected by physical growth | Lifespan does not flow even if the lid is opened | The amount does not increase even if added

Etenkiri can make life flow (this is a world view I added)


If there is anyone who does not understand, please leave a comment.

I'm not good at explaining...🥺
