Brilliant Detectives

**Brilliant detectives** are a core mechanism of the Mizuhanome System. They are personas based off and controlled within an id well by pilots of the Mizuhanome. The brilliant detectives are integral to Kura's investigation process, as it is only through them that they can explore and investigate id wells.

## Overview

Once a pilot has entered the Mizuhanome, the brilliant detective is summoned within the created id well, waking up shortly afterwards with no memory of who they are. This is presumed to be a safety mechanism of the Mizuhanome, should a pilot end up in their own id well and "fall into dogma". However, as seen with Anaido, it's possible for a pilot with specific brain damage to retain their memories. Should a brilliant detective end up in their own id well and remember who they are, they will "fall into dogma" and trigger a "well storm", though this won't happen if the pilot is dead. Should this happen, the Wellside will be unable to view them, trapping the detective inside their own subconscious. However, should the detective return to Kaeru's body at the eye of the storm, they will become visible once again and can be extracted.

After seeing Kaeru's face for the first time, the brilliant detective will "remember" their name (which is always different to their actual name) and their purpose, which is to solve the mystery of Kaeru's death. Should they die while attempting this, the pilot will need to be ejected, and the brilliant detective re-injected. The brilliant detective can also be pulled out at anytime without dying, though the experience can still be distressing. As a pilot retains all their experiences in an id well, repeated insertions can be physically stressful. Should the pilot themselves die in the cockpit while the brilliant detective is still active inside a well, the Mizuhanome will instead just repair the brilliant detective's data, effectively making them immortal within the id well.

Once a brilliant detective comes into existence, the respective pilot's id well automatically updates to feature a Mizuhanome cockpit, which always leads to Kiki Asukai's id well.

As a rule, brilliant detectives appear as a younger version of the person operating them, wearing flashy, highly stylised clothing. Their overall personality largely reflects that of the pilot, though is noticeably different, possibly an effect of the lost memories and differing neural patterns, displaying character traits not shown by their original selves. In a sense, a brilliant detective can be seen as an unfiltered reflection of their pilot's true nature, their most basic instincts and desires uncontaminated by trauma or societal obligations - their id.

### **Eligibility**

There are three generally accepted pieces of criteria for one to become a Mizuhanome pilot and thus, brilliant detective:

* Having good deductive reasoning.
* Having killed before or having shown murderous and/or suicidal intent.
* Having an active desire to kill.

In other words, the pilots of brilliant detectives are killers themselves. For this reason, it's not uncommon for the Kura to pull pilots from their own prison population. These three rules are somewhat loose however, and seem to function more as general guidelines, as seen when Nahoshi Inami was made a pilot out of sheer desperation, despite being in a coma at the time and having shown no deductive powers up to that point.

## List of brilliant detectives

 **Nahoshi Inami** | **Hakaido****Seer** | Active | The fifth brilliant detective, Hakaido is the persona of serial killer Nahoshi Inami, created while the latter was still in a coma. Created as a necessity after the Kura found themselves short a detective, Hakaido is unique in that she is accompanied by a "Seer", who acts as her eyes, Hakaido herself being blind, and thus unable to gather clues or even see Kaeru to remember her identity.

 Trivia

* All of the brilliant detectives' names contain the kanji for well - "井", a reference to the id wells. Additionally, the combination 井戸 (read "ido" and present in all the names) means "well".
	+ Hijiriido is noted as being the only brilliant detective to have a full name. The reason for this is unknown.
