## Lexicon entries

### Gunjoji Detective Agency

An investigation agency run by Sosuke Gunjoji, also known by the alias of "Degenerate Detective." True to this moniker, Gunjoji leads a hedonistic. life of self-indulgence. A good-for-nothing, he gambles often, referring to it as "brain training" to excuse his greed. He does have a good side, however--for those who are truly in need, he'll always accept a case, regardless of pay. Wato may often be frustrated by Gunjoji, but he still idolizes him all the same. Since he hates heavy chore work, the agency is more often than not buried in trash. Wato spends the bulk of his part-time work there. The moral of the story is: be careful what jobs you apply for.

### Ikusa School of Arrest Techniques

A style of self-defense that Wato learned from his mentor, Mr. Gunjoji. "Arrest techniques aim to subdue adversaries while minimizing injury, and are widely practiced by public servants, including police officers. The Ikusa school builds upon and refines these techniques by using everyday objects for practical defense, enabling the user to fight in a variety of situations. Put simply, the style is specialized for street fights. Its creator, Otogiri Ikusa, is infamously know as the "most sinister hodvenard to ever walk this earth."

### Cuff-fu

Within the Ikusa school of arrest techniques is "cuff-fu," a peculiar art that involves fighting with handcuffs. It is characterized by using cuffs like brass knuckles to bolster both offense and defense, and specializes in immobilizing an opponent's limbs, a general focus of the Ikusa school. Since handcuffs can easily be concealed in one's pocket, the art has proven quite popular among those who are less aggressively inclined, such as Wato. However, unlike other weapons, nothing in daily life resembles the shape of handcuffs, making any on-the-fly improvisation difficult.

### Detective Alliance

Founding Detective Vidocq heads the Detective Alliance (DA), an officially sanctioned organization comprised of 100 detectives and support staff. All requests and other pertinent information are communicated through dPads: electronic devices exclusive to the DA, and even those within its ranks are not privy to the full details of the organization's inner workings. The Detective Alliance's activities are supported by funding from benefactors, as well as by any compensation earned through solving cases. Regardless of scope, anyone can petition the aid of the DA, so long as they have a connection to the organization. Clients are not limited to the private sector, as even government institutions, such as the National Police Agency, will employ the services of the DA. As such, a wide variety of requests are accepted and completed on any given day. When a request is made to the DA, the agent deemed most suitable for the job is dispatched. After confirming an incoming job through their dPad the detective will then seek the client out and handle the case independently. Once a client confirms that a case has been resolved, the assigned detective is rewarded, with each successful case adjusting their rank accordingly.

### Detective Rank

Detectives of the DA are assigned a number to indicate their rank within the organisation. These ranks are determined by an individual's achievements. The higher one's rank, the more difficult the cases they receive. When egos collide and neither side can reach an agreement, the higher-ranking detective will be given priority, provided that there is no clear evidence that works against their favour. As detectives tend to be rather self-important, the ranking system was created to mitigate any otherwise inevitable conflicts of opinion.

### Seven Forensic Friends

Techie Detective developed these seven high-performance support tools in collaboration with the DA. Though he possesses a variety of other gadgets, this term refers specifically to those intended to form the foundation of his detective work. Their peculiar names stem from Techie's strong sense of camaraderie toward his creations. Due to his physical limitations, Techie had few chances to play with children his age. As he found solace through inventing, it only follows that he would think to build his own companions. Referring to them as "Tools" is sure to earn you Techie's ire, so be sure to use the term "Friends."

### Danger Magnet

Doleful Detective's ability, which attracts dangerous phenomena to his person. Its exact mechanics are unclear, but an unkind explanation would be that he's "fatally unlucky." Doleful may be an extreme example, but some people are just that ill-fated. There are any number of stories on TV about those who survived multiple serious accidents and were always able to bounce back. That said, they are well-known simply because they survived. There may well also he those unlucky souls who died without recognition, completely unnoticed by the rest of the world. Doleful's success as a detective is due to both his misfortune, which attracts danger, and his fortune, which allows his survival.

### Classified Detective

A detective alias handed down from generation to generation in the Iwai clan, the most prestigious family in the domestic detective industry. Just as the name suggests, they never act unless it concerns a case of the utmost national secrecy. Even among the upper echelons of the Alliance, only a scant few have ever seen this individual. The clan always acts under the guidance of family head Mikazuki Iwai, solving cases quickly and dispassionately.

### Detective Gentleman

A genteel detective who always wears a suit. He styles his alias in reversed order because he sees himself more as a gentleman who is a detective, rather than the other way around. His eccentricities are unrivaled within the DA. Despite being a talented investigator, he only accepts cases that suit his personal sensibilities. According to his apprentice, however, he is surprisingly easy to manipulate once a beautiful lady is involved.

### Wire Saw

Official Designation: Lethal Artifact Wire Saw. Usually referred to simply as "LAWS" within the DA, this tool is generally used to open up sealed spaces and ward off assailants. The saw is a fiber composed of a special alloy and fitted with sharp, minuscule teeth that enable it to slice through anything that makes contact. There is, however, a side that can be touched without getting cut, as well as gloves made from the same alloy. Both of these, once acclimated to, allow one to handle the saw with ease.

### Q Incident

This phrase indicates events, individuals. creatures, or phenomena that are deemed to have a potential impact on the future of the country. The Q stands for 'quintessence,' but there are many theories on what this means, and mysteries abound. Any subject designated a Q Incident is limited to authorized individuals, who are permitted to employ extralegal measures in dealing with them. If, however, a Q Incident is not deemed to be a threat then no restrictions are placed on its activities. As a matter of fact, Ideal Detective is one of the few individuals designated as a Q Incident, and she leads the DA of restrictions.

### Super-Palate

Gourmet Detective excels in her analytical ability to connect scents and tastes to foods. Her past experiences have given her a strong resistance to poisons and molds, making her uniquely optimized for this power. The most extreme aspect of the Super-palate is that it's capable of sniffing out the scent of lies. While much research remains to be done on this, people react to emotion, causing changes to components in the bloodstream, as well as the particles that make up sweat. For creatures with keen noses such as dogs, research has shown that compositional shifts like these can be detective via olfaction. The same is believed for Gourmet. Unlike Rowdy's more universal senses, however, if Gourmet is unable to perceive something as 'food,' she can't work her magic on it -- a downside to her ability.

### Hyperhymesia

Bookworm Detective's superhuman power of recollection. Also called "super-memory" or "total recall," this ability allows her to record all visual information as images. There are fewer than 100 people in the entire world with this condition. Such individuals have developed a region in their brains for recalling autobiographical memories, though the principles at work here are yet unclear.

However, as Bookworm Detective can attest, negative past experiences are easily recalled as well, strengthening the memory each time. This results in a very high percentage of people with this ability feeling mentally overwhelmed.

One might say that this inability to forget is quite the splendid affliction.

### Founding Detective

A deeply mysterious pioneering detective by the name of Vidocq. Ranked #1, he is the main player behind the creation of the DA. Although his powers of insight are top-class, he is never seen in the spotlight. He generally communicates via phone, scrambling his voice as he does so.

As the guiding force of the DA, he typically plays a dedicated support role in investigations for major cases, which have been on the rise.

During The Dayless Night Incident 13 years ago, he preempted the schemes of the main culprit, Lucifer, gaining worldwide recognition for his role in minimizing damages and casualties.

### Residual Thought

An oft-discussed topic in occultism. In the DA, the term is used to refer to thoughts that can be sensed from objects and occurrences.

As the name suggests, these are remnants of past thoughts. Naturally, possessions and events reflect the cogitations of others to a considerable extent. Thus, in theory, their respective owner or cause can be traced by "reading" them.

Ideal Detective can, in fact, interpret these residual thoughts, enabling her to solve cases by, for instance, accurately guessing what sort of conversations took place in the past.

The renowned Sherlock Holmes' "abductive reasoning" operates on a very similar principle; that is to say, this ability is not merely the work of an overactive imagination.

### Diabolic Detective

Workaholic Detective's previous alias. A member of the Shizaki family, a line of assassins, he acted in a similar capacity to his role as Diabolic Detective even before he finished compulsory education.

It's worth noting that this family is characterized by their unusually high red blood cell count. As a result, they don't tire easily, and their wounds are quick to heal. Their bodies are a mystery in more ways than one; by controlling their bloodstreams to a certain extent, they can boost their physical abilities for a brief period of time.

However, this murderous family trade is now defunct, with many Shizaki descendants unaware of their dark lineage. They have since changed the kanji of their surname and live peacefully.

### Dayless Night

According to Renegade Detective, this criminal organization formed from the successors to Lucifer, the most nefarious criminal in history, as well as the mastermind behind The Dayless Night Incident.

There are no further details, but Renegade says that he, Downtown, and the Duke are all members.

### Secret Police

A certain powerful politician used the opportunity presented by The Dayless Night Incident 13 years ago to propose creating this detective organization. The organization's goal was to create powerful, ideal detectives whose capability to deter crimes would rival that of the former Pinkerton National Detective Agency. Unlike the present-day DA, they solved no private civilian cases and had no interest in saving lives. Instead, they forwent ethics to focus on weapon development and human experimentation, going so far as to kidnap and imprison children.

Ideal Detective incited those unhappy with this direction, dismantling the organization from within and incorporating its personnel and technology to form the current Detective Alliance.

Maestro Detective, the leader of the Secret Police, wound up banished by Ideal Detective, and has not been heard from since.

### The Quartering Duke

A deranged killer who publicly streamed a live murder on the internet out of the blue. Self-described as an "entertainer," his modus operandi is two simultaneous victims. In the 6 months since his first homicide, the death toll has climbed to over 100 -- a scale unreached by any serial killers that came before.

There are few clues to his true identity, as the voice heard on broadcasts is scrambled. The police have investigated diligently, but in vain, failing the so much as uncover the Duke's gender. As if to mock their efforts, there is no consistency to the Duke's ideologies, claims, mannerisms, or even modes of self-address in his irregular broadcasts, making him all the more elusive.

### Pinkerton National Detective Agency

In a certain country is a historic detective agency whose name is known by all. Founded by Allan Pinkerton, a detective famed for foiling an assassination attempt on the president.

His fame soon spread across the globe as his practice expanded to cover presidential security, rooting out spies, gathering intelligence on anti-governmental organizations, and tracking criminals as they work in the shadows -- all in the interests of national security.

One theory even posits that the FBI itself may be modeled after the Pinkertons. As the world continued to modernize, however, many of their intelligence activities became outlawed. With local police forces on the rise, the public gradually grew estranged from the Pinkertons. These days, the organization is not believed to engage in any detective work.

Did they bring justice or corruption? Were they heroes or villains? Merciful saviors of harbingers of death? Only time will tell how their history is told.

### Super Human Experiments

The true purpose of the human experiments conducted by the Secret Police underground.

After a special neurosurgery, the subjects were exposed to lethal danger. This activated regions of their brains far beyond the normal capacity, inspiring new means for survival. It is said that this led them to develop "sixth senses" (though the veracity of this is dubious).

"If there had only been a great detective with this sixth sense, tragedies like The Dayless Night Incident could have been avoided. Society's future depends upon ideal detectives who prevent these travesties from occurring altogether, rather than responding after the fact."

This was a statement made by Maestro detective, and at the time, employees of the Secret Police could not object. The Dayless Night Incident had only recently claimed numerous lives, and people undoubtedly harbored much fear over the inscrutable atrocities.

### Denouement

A power born of the superhuman experiments. By processing visual data that is usually imperceptible, its user is able theorize future events -- a sort of pseudo-precognition.

There are, however, reports of past events being seen as "residual thoughts," among other experiences unable to be explained by scientific means. Research on these phenomena continues to this day.

Because it causes inordinate amount of data to be processed by the brain in a single moment, the ability places an extreme burden on the mind, and sustained use is not recommended.

As Ideal Detective is designated as a Q Incident, some know of her unusual talents. The specifics, however, are kept confidential.

### Aesthetic Eye

Posh Detective's ability, which allows her to gauge the quality of whatever she targets. Her parents both retain pride in their family name to this day, and have thus placed great importance on "aristocratic" etiquette, dining, and knowledge.

From a young age, Posh herself has held much interest in the genuine historical documents and artifacts stored in her privileged household. Owning to this, she has gained keen senses that can spot any fakes or forgeries with ease.

The ability is a perfect complement to her haughty demeanor; she isn't just putting on airs when flaunting her upper-class status. However, this sensitivity's also been her ruin, as she is not able to afford "authentic" ingredients for her meals.

### SPX Series

13 years ago, The Dayless Night Incident resulted in horrific crimes across the country. Seeking to counter this, the Secret Police developed these robots in order to track down criminals.

In addition to terrain and obstacle-detecting laser sensors, each model boasts a specialized tracking function that engages "Pursuit Mode" upon detecting a target.

Until their target is no longer detected for a certain amount of time, they will continue their pursuit, neutralizing any obstacles in their way.

As a failsafe during their initial development, a sound byte was installed in the machines that, if parsed, would deactivate them. Inspired by this riddle-solving, the personnel dubbed their beloved creations "sphinxes" -- or "SPX" for short.

Maestro Detective, head of the Secret Police, became increasingly reckless in his pursuit to make the SPXs a more powerful deterrent. This ultimately resulted in tragedy, as droves of children wound up dying in his research facility.

### Invisible SPX

Official designation: SPX-02H

The second SPX model, developed for stealth, it has the ability to camouflage itself by projecting its surroundings back onto its body.

However, its only means of detection are its movement-sensing lasers and sound sensors. As cameras would hinder its stealth functionality, it receives no visual input.

The invisible SPX sneaks up on human sound sources before using its horn-like spikes to render them helpless.

Due to an overemphasis on stealth in its design, both its lethality and tracking capabilities are lacking.

### White SPX

Official designation: SPX-01C

The first SPX ever developed, this model serves as the foundation for the entire series.

It has a low lethality rate, utilizing what is essentially a stun gun to shoot electrified spikes that run high-voltage currents through their targets, immobilizing them.

One of the three openings on its exterior leads directly to its power source. It is possible to power down the machine by launching an attack on this area.

While nearly all SPX-01Cs have since been scrapped, a special prototype model developed by Maestro Detective current patrols the hidden underground passages, expunging intruders with its lethal voltage and spikes.

### Invincible Detective

A mysterious individual who successfully fled from the Secret Police's experiments. Believed to possess unique powers, they were given the alias "Invincible Detective" after they managed to survive every test imaginable.

However, because experiments were always conducted on groups of five, Invincible's identity remained unclear.

As researchers cautiously investigated the true nature of this peculiar ability in a way that would not inadvertently kill the child, their oversights allowed Invincible and the rest of their group to escape the facility.

(Invincible is presumed to have determined that if their identity were pinpointed, everyone's lives would end up at risk.)

Ever since, "Invincible Detective" has been used as a general term to refer to the escaped child subjects. Though great efforts have been made to track them down, not even one has been found as of yet.

### Snarks Research Facility

A facility located within DA headquarters. It was originally built when the Secret Police was established, and vestiges of that time are reflected in the structure's general layout.

The personnel that inhabit the island are highly skilled, with many of them unable to live on the mainland for any number of reasons. Such is the role of the DA, however -- to take in those who possess talents, yet ample reason to avoid the public eye.

The facility's name itself refers to the eponymous "creatures that don't exist" from Lewis Carroll's "The Hunting of the Snark."

### Underground Maze

A facility located beneath the Detective Alliance headquarters. The religious order that had originally inhabited the island built these tunnels to hide inside during emergencies. They have since been repurposed by the Secret Police, who purportedly installed lighting, hidden doors, and secret passages.

Irksomely enough, the traps and sentry robots from those days are still active. It was determined that decommissioning them was not necessary, and thus, they were simply left as they were.

### Dungeon

In the past, victims of the Secret Police's human experiments were confined in this subterranean dungeon.

It was constructed before the Secret Police erected the manor above it, and is believed to have originally been some kind of facility built by the religious order that had been exiled to the island in the past.

Due to its location, temperatures within the dungeon tend to be low. Wall-beds were installed to prevent subjects from succumbing to the cold.

### Collar

Maestro Detective is said to have developed this compact explosive device during his days in the Secret Police.

Its official designation is "WENET," named after the Egyptian goddess who was depicted with the head of a rabbit. As this reference is rather obscure, most simply refer to it as a "collar."

It attaches itself by "biting" into the skin, and is so slim that it can be mistaken for a tattoo at first glance. Its explosive force, however, is highly lethal.

Even within the DA, details about how to detonate the collars are limited to a select few individuals. They are primarily used as a means to rein in dangerous or unpredictable targets.

### Meicho Aragi

The architect of Gormenghast Manor. Aragi designed one building after another with eccentric features, complex mechanisms, and unusual facades -- his architectural signatures.

This won him the staunch support of wealthy magnates, and he proceeded to construct an entire generation.

Unfortunately, mysterious incidents began to occur in his buildings. In a complete reversal, his works began to be viewed as haunted, and in time, Aragi vanished.

These days, the buildings are sought after by quite a few people who are drawn in by their paranormal appeal. An inexplicable number of them, however, wind up getting involved in some disturbance or another.

### Collar Command

Investigation has revealed two conditions that can trigger collar detonation:

1. A detonation command is entered by a designated Observer via dPad.
2. An Observer goes into cardiac arrest within a 10-meter radius of the target.

If these conditions are met three times in total, the collar detonates following a set warning period.

To prevent potential disassembly and theft, the collar will explode if dismantled through any unsanctioned methods.

### Black SPX

Official designation: SPX-04A.

The final model of the series, characterized by its black exterior.

Just before the Secret Police were abolished, Maestro Detective, out of fear of reprisal from Invincible Detective, developed this model for the express purpose of fending them off.

Its treads, laser sensors, and stabilizers have all been enhanced, allowing it to traverse anything from open spaces to grassy terrains.

Its defining feature is its sturdiness, and while its lethality is lower than that of the red model, it is durable enough to face off against Ideal Detective, endure the strikes of rubble and logs, and even withstand an explosion.

It tracks down targets using the designated blood records stored in its database. When Ideal Detective ordered the SPX series to be scrapped, a faction still sympathetic toward the vision of Maestro Detective's technology rebelled by placing this model in permanent storage within the underground hangar.

### Red SPX

Official designation: SPX-03G

Characterized by its bright red exterior, this model indiscriminately attacks any target it detects. Unlike other models, it lacks an emergency shutdown feature, making it a pure killing machine.

On top of heightened tracking abilities, it sports enhanced laser sensors that aid its movement. Upon losing its balance, it uses internally stored wire hooks to perform evasive maneuvers. In short, there are no openings in this model's defenses.

This propulsive power of its engine can eject blades from its apertures with enough force to damage even Armor's suit. Because it specializes in lethality, however, its defenses are extremely brittle -- to the point where Invincible Detective managed to destroy one in the past.

Its demise resulted in the development of the black SPX, which is able to withstand any and all attacks.

### Morgue

The DA's headquarters is located on this remote island, which is generally believed to be uninhabited.

Morgue features rare twin calderas and is surrounded by sheer cliffs, preventing any passing ships from peeking through them. The central volcano is still active, however, and the threat of eruption looms even now.

Originally, Morgue had been inhabited by an ostracized religious group. Although they were forced to relocate due to volcanic eruptions, traces of their presence still remain.

### Gormenghast Manor

Gormenghast bears the name of a fictional castle from a well-known fantasy series of the same name.

It appears to be an elegant manor at first glance, but due to the architect's particular inclinations, all manner of tricks, traps, and pitfalls are hidden within its walls.

Many of these features were deemed to be in poor taste and removed later on, but others, due to the complex of their construction, were left untouched for fear that an unskilled removal could result in the manor's collapse.

Additionally, back when the Secret Police used the building, Maestro Detective added underground facilities beyond the architect's original vision.

Because of this, although the manor functions as lodging for DA members, most opt to sleep in the research facility instead.

### Maze Cipher

The first cipher solved in the underground maze, so named by Bookworm Detective.

According to her, "It's a fabricated writing system formed by fusing Hangul with Estrucan scripts. It was likely used while handling sensitive information within the organization."

"How did I figure this out? If you split the characters in half horizontally and compare their top and bottom portions, you'll notice that they compromise five basic shapes. Even an ape would realize these represent vowels."

"Next, the empty spaces on the bottom right confirm that the text is read left to right. If we assume the use of an alphabet based on these characteristics, the answer reveals itself in due course."

### Dpad

Members of the DA are provided with this personal tablet device.

Each dPad (Detective Pad) has a symbol and unique ID code engraved on the back, allowing the device to function as proof of the owner's affiliation with the DA in addition to serving as their sole means of communication with HQ.

dPads possess a special communication system, so contact is still possible even in remote areas without regular network coverage.

Additionally, it contains detailed maps of the entire country, as well as various in-depth data on cases, making it an indispensable tool for any detective. Apart from that, dPads possess myriad other features and classified information, and thus have several layers of internal encryption. Their exteriors are also crafted from a special material that makes physical damage, disassembly, and analysis almost impossible.

Upon reaching rank 50 or beyond, a detective may have their device's size and design customized as a reward. Within the DA, having one's own custom dPad is the mark of a full-fledged detective.

### Detective Alias

All detectives belonging to the DA go by an alias. These serve to disguise the bearer's name and identity, as well as convey the individual's specialty.

In most cases, and single word pertaining to this speciality is placed before "Detective." There are, however, instances like Workaholic Detective, whose alias was proposed by Ideal Detective as a jab at his lifestyle. Detective Gyaru, on the other hand, disliked the way her alias sounded, opting to change it to "Downtown Detective" to reflect her usual place of work. In practice, such concessions are often made to accommodate a detective's particular naming sense.

Revealing one's true name is strictly forbidden. Posh Detective, however, disclosed her identity as a PR move for her company, so even this rule can have exceptions if one petitions the DA.

## Cases

### The Dayless Night Incident

The popular name for a series of incidents caused by the Morningstar of Dawn Society, which at the time commanded public support and even exercised influence in the political sphere.

Sect founder Jun'ichi Nanase, who went by the name "Lucifer," targeted opponents by kidnapping, confining, and brainwashing them. He is also believed to have carried out a number of cruel human experiments, though the building where this is purported to have taken place has since collapsed in a disaster.

Lucifer utilized TV stations and internet broadcasts to steal the hearts of viewers with his witty comments and charismatic mannerisms, steadily growing his hordes of believers.

Thirteen years ago, Lucifer attempted to take advantage of the chaos after a major earthquake by plotting to release poison gas, resulting in his capture by the world's premier detective, Vidocq. Vidocq received global recognition for this accomplishment, eventually leading to the establishment of the DA.

Although 13 years have passed since he was apprehended, Lucifer's followers have continued committing crimes in his name, unabated.

The true irony is that by solving this case, Vidocq triggered an exponential increase in domestic crime, thereby fueling the ongoing "detective craze."

### The Case of the Quartering Duke

Otherwise known as the Quartering Duke Incident, these names are used to refer to the numerous murders committed by the notorious serial killer, the Quartering Duke.

Each occurrence is defined by two key aspects: two simultaneous corpses, and the presence of the Duke's logo on their possessions. After half a year, over 100 lives have been claimed.

The victims have been discovered nationwide, with a stark lack of evidence left behind at the crime scenes. This has led some to believe the killings to be the work of an organization; the truth, however, remains uncertain.

Due to these happenings, the number of people too afraid to go out increases by the day, with some companies even allowing their employees to work remotely.

Upon being designated as a "Q Incident" -- a crime capable of throwing the whole country into chaos -- the National Police Agency contacted the DA for their assistance in the investigation.

### Foiled Bombing at Tokyo Govt. Bldg.

"The government building turns into a giant robot during emergencies, right? That I gotta see."

The case began with this simple prank phone call.

The culprit, who called themselves "Jack the Bomber," coerced the authorities into playing their "games," which they had modeled after a variety of well-known urban legends.

Threatening to bomb the government's main offices should his players lose a game, Jack toyed with the police while holding thousands of lives hostage.

However, once the alliance dispatched Ideal Detective, she bested each and every game with aplomb. Upon apprehending the culprit, who had been "enjoying the show from the front row," she was able to prevent the bomb's detonation.

Ideal's success with this case garnered her widespread recognition within the police force, ultimately earning the DA their trust.

### Foiled Mass Shooting in Akihabara

One day, a puzzling announcement of a planned mass shooting was posted to the internet out of the blue.

Authorities wrote it off as a prank, but Ideal Detective, who had managed to crack the poet's hidden message, realized the gravity of how many lives were in danger.

While police blindly attempted to set up a stakeout, Ideal headed to a certain maid cafe and requested that her server draw a message for her in ketchup on her omelette rice.

"Give it everything you've got, okay? I just need you to write, 'I am the culprit.'"

Realizing that Ideal had seen through their entire ploy, the culprit abandoned the plan. Thus, Ideal was able to close the case before it could produce even a single victim.

### The Case of the Vampyre

In a certain country, corpse after corpse was discovered, with each displaying an unusual amount of blood loss.

The culprit was believed to have bitten into the victims with inhuman teeth, partaking in their blood.

The outrageous incidents came to be known as "The Case of the Vampyre." As the teeth were artificially made and no blood remained, no sufficient evidence could be found. Having failed to discover even so much as a motive, local authorities were close to letting the case go cold.

It was at this time that a man appeared before the police, introducing himself as Mystic Detective.

He pointed them to Lugosi Kamaras, a man who suffered from allotriophagy, thus revealing the true nature of the case.

Under pressure, Kamaras utilized his unnatural physical constitution to flee abroad, eventually contributing behind the scenes to the events of The Dayless Night Incident.

To this day, the fates of Kamaras and Mystic Detective are deeply intertwined.

### The Case of the Ikebukuro Ripper

One day in Ikebukuro, the upper half of a high school girl's severed body was discovered.

The incident paralleled the urban legend of Teke Teke, the vengeful spirit of a schoolgirl who was cut in two. This captured the public's imagination, and rumors spread that the victim had been a bully at school, and that a girl she had bullied into committing suicide returned as Teke Teke to take revenge on her.

Downtown, who was not a detective at the time, sensed something was amiss and began looking into the flurry of Teke Teke rumors herself.

What her search revealed was that the victim had not been the school's head bully, and that another student was the actual ringleader. In other words, the Teke Teke crimes may not have been over yet.

Downtown gave up trying to convince the police after they brushed her off, instead relying on her network of friends to launch a full-scale investigation.

Following this case, "Detective Gyaru," as she was formerly known, gained widespread attention, resulting in her induction into the Detective Alliance.

### The Case of the Lycanthrope

The bodies of a renowned literary figure and his wife were discovered in a quiet residential area, seemingly mauled by some sort of beast. According to the lone survivor of the incident, their daughter, the culprit had the appearance of a werewolf -- and an abnormally small one at that.

Of course, the police did not take her claim seriously. The only person who would was Mystic Detective, who had been dispatched by the DA in response to her request. Mystic listened to the girl's words in earnest, chuckling as her concerned neighbors flocked to her in concern.

"...I see. So a lycanthrope truly walks the earth. Though this one appears to be of man-made origin."

Naturally, the police paid no heed to his words either, and so, Mystic headed to the culprit's home to hunt the beast himself...

### The Case of Building No. 6

Workaholic Detective was once requested to act as a personal bodyguard, and wound up visiting Building No. 6, one of the eccentric manors constructed by famous architect Meicho Aragi.

The owner of the building had received a threat declaring that they would be murdered. Amused, the owner decided to invite all those who held a grudge against them over to the manor.

Within the building's hexagonal rooms, which were connected to each other like honeycomb, the murderer killed one guest after another.

Workaholic was swamped by the investigation, but a curious young boy caught his eye after he discovered a trove of evidence connecting the various crime scenes. The boy in question was said to have lost his family due to his penchant for attracting danger.

Workaholic approached the hapless boy with a proposal:

"How would you like to try using that ability of yours to catch the killer?"

Such were the origins of Doleful Detective, though his is another story to tell.

### The Case of the VR Killer

This particular incident involved the use of a virtual reality software known as VR Communication, a popular tool for online socialization. A player using this program, typically referred to as VRCM, was murdered in real life, with the crime scene recreated in the virtual space, resulting in a most unusual homicide.

Techie Detective, who was well-versed in the world of VR, was assigned to the case. As investigations on VRCM got underway, something strange came to light: Users had seen the victim's account active after the time of the murder.

Another person was thought to have gained unauthorized access to the account, but they could not be pinned down, and the mystery only thickened.

Techie made a vital observation, however: The culprit's goal hadn't been to kill the actual individual, but rather the VR model they were using...

### The Minamijuji Kidnapping Incident

A child was abducted in Minamijuji, a suburb of Tokyo.

Rowdy Detective happened to be on the scene and, using her keen sense of smell and brute strength, tracked down the culprit, solving the case without even accepting a reward.

A group involved in illicit drug trades was linked to the incident, which soon developed into an intense fight. Once the dust settled, however, Rowdy didn't have a single scratch on her.

In the days that followed, the culprits allegedly tried to exact their vengeance on Rowdy with the help of a local gang, but a mysterious woman crushed their plans before they could act. To this day, the full truth of the case remains unclear.

### The Case of the Undead Cyborg

Nanana Nanajo was a young woman from the Jujo Group -- one of the nation's six major conglomerates -- who had the misfortune of witnessing a murder.

She herself then became a target of the Undead Cyborg, a famed assassin who could survive any mission.

The DA dispatched Armor Detective, rank #90, to act as her bodyguard. The client was highly displeased to learn that the detective assigned to her had intellect far beneath her own, but Armor nonetheless revealed the secrets of the unkillable cyborg and managed to keep them at bay.

Of the many detectives in the DA, few have faced an assassin head-on the way Armor had done. Even now, the majority of requests for him are not detective work, but protection jobs.

### The Case of the Jujo Family Treasure

The Ichijo family belongs to the Jujo Group, one of the nation's six conglomerates. Ryuga Ichijo, the former head of the family, left a will that incited chaos between the remaining family heads.

The will stipulated that whoever solved its cipher would receive a massive buried treasure as inheritance. This, of course, gave rise to tensions within the Jujo Group, to the point where those involved would not even balk at murder.

The Rukojo family, which held much power within the group, contracted the DA to solve the riddle quickly, planning to distribute the wealth equally between all the families.

The DA was able to deduce that the cipher was based on the literary works beloved by the late Ryuga Ichijo, and thus dispatched Bookworm Detective, who solved the case with flying colors.

There was, in fact, an assassin lurking behind the scenes with plans to take out Bookworm. However, Ideal and Mystic were able to foil the scheme in time.

### The Case of the Sea Turtle Soup

An elderly fisherman turned himself in to the authorities, admitting that he had once consumed human flesh. The old man had been shipwrecked and forced to survive alongside his companions. In time, his mind became sick and cloudy, prompting his friend to prepare him a bowl of sea turtle soup.

However, years later, the old man happened to eat sea turtle soup again when he realized its flavor was completely different from what he had tasted all those years ago.

By this time, all his friends who survived the shipwreck had passed away. With no way of knowing the soup's true contents, he gradually convinced himself that he had actually consumed human flesh.

As the statute of limitations had expired, he would not be charged for any crime. Even so, the DA wished to put the old man's mind at ease, dispatching Gourmet Detective to help solve the mystery with her unparalleled palate.

### The Case of the Endless Night Shift

In a particular office building, the lights curiously began to flicker on their own come nightfall, day after day.

A rumor soon spread that it was the work of the supernatural -- the ghost of a former employee who died from overwork. Thus, the DA was tasked with investigating the case.

Workaholic Detective, who had been dispatched by the DA, rigged a trap using wires to reveal the culprit: a man who had joined the company at the same time as the employee who passed away.

The CEO of the company did not apologize or compensate the surviving family, but instead mocked them openly. In retaliation, the culprit decided to cause a stir.

When Workaholic reported his findings to the CEO, the perpetrator was fired. However, the DA was able to produce documents outlining the company's misconduct, ultimately leading to an official indictment.

"Companies that make enemies out of their employees won't last long," said Workaholic, a contented smile on his face.

### The Case of the Shinjuku Rainwalker

This bewildering case involved a string of murders that only occurred on rainy days. No clear motive could be determined.

As the rainy season began, the National Police Agency needed a quick resolution to the case, and so they turned to the DA for help. Being the individual best equipped to understand the psychological makeup of this "Rainwalker," Renegade Detective was assigned to the case.

The case was ultimately resolved. However, due to Renegade's skillful incitement, an accompanying officer made a failed attempt to shoot the culprit. Renegade was punished severely for this misconduct, and following the incident, the aforementioned officer quit the National Police Agency and joined the DA as Inspector Detective.

Surprisingly, Inspector and Renegade have occasionally been paired up for investigations and appear to be on good terms.

### The Gingami Family Suicide

Years ago, a bloodstained child was found wandering a residential area. In the young boy's home was his father, dead by hanging; and his mother, whose corpse had been mangled beyond description.

According to the child's testimony, his mother had gone mad upon discovering her husband's dead body and flew into a frenzy, attacking him.

The child was apparently able to take hold of the mother's weapon, killing her in retaliation.

Clearly an act of self-defense, there was plenty of reason for sympathy. Yet the boy was still treated as a crazed killer by the public, becoming the topic of chilling tales and gaining the nickname of "Child A."

The reason for this was simple: During a TV interview, the boy cheerfully recounted the murder of his mother, how thrilling it had been, and how much he had enjoyed it.

Many have sought Child A out to sate their dark curiosity, but as these meetings have consistently ended in disaster, doing so is not advised.

### The Collapse of Never-Child CC

There was once a notorious juvenile detention center known as the Never-child Correctional Center.

The facility housed youths who had committed grave crimes and employed borderline abusive educational methods to thoroughly neutralize the children's mentalities.

As part of their educational process' goal of fostering independence, the older children were granted some autonomy, resulting in bloody power struggles among the juveniles. No child left the way they had been when they first entered. Such was the goal, at least.

However, these power dynamics shifted when Child A, the infamous serial killer, entered the facility. Each faction scrambled to get Child A on their side, resulting in a violent struggle with many casualties.

The facility closed soon after, with Child A being sent to another correctional center. At the time, he shared the following with a smile:

"At least that kept me entertained for a bit."

### The Case of the Altered Mona Lisa

A second variation of the famous Mona Lisa was discovered in Italy and dubbed the "Alternate Mona Lisa."

Although its authenticity was hotly debated, an exhibition was held at an art museum. Ideal and Posh happened to be visiting at the time, and so they went to go see the work.

Posh knew the painting was a fake the moment she laid eyes on it, however. What's more, she suspected murderous intent.

Right before the exhibition, the painting had been covered with numerous extra layers of oil paint. On top of damaging the art itself, the paint was highly flammable and moments away from igniting.

Posh Detective swiftly and successfully put out the fire with Ideal Detective's aid. The museum's owner, who had been responsible for managing the painting, was then arrested.

Their motive stemmed from their frustration toward the public for blindly flocking to see a blatant fake just because it was publicized, as well as toward the media for egging them on.

### The Nanase Conference Case

During a conference with the Nanase Group, one of the nation's six major conglomerates, an announcement broke out that a murderer had infiltrated the premises.

By direct order of the culprit in question, Renegade was dispatched to the Nanase estate, where the meeting was being held. While there, he delighted in the Nanase's strange family customs as he searched for the perpetrator.

However, under the provocative murder of a female client, the culprit incurred Renegade's wrath. This prompted Renegade to hound them relentlessly, ultimately forcing a confession out of them.

As they awaited the police's arrival on the scene, Renegade tortured the culprit using unfathomably horrific methods.

They have since been taken in by authorities and are physically secure, albeit certain never to leave the "hospital" in which they are held.

There's nowhere to run in a closed circle of people -- the culprit should have considered that the same applied to them as well.

### The Case of Building No. 1

The elusive, eccentric architect Meicho Aragi is believed to have constructed a number of so-called "enchanted manors." One of them, Building No. 1, became the site of a serial killing case.

The case occurred before Senior Detective became a member of the DA. Within the manor, the shape of which was inspired by the kanji for "1," Aragi discovered a mysterious space that did not appear on his blueprints.

In time, he revealed the presence of a secret resident who had remained hidden within the walls for years.

The truth behind the case caused such a stir that it was adapted into a movie and TV show. Senior Detective, an unknown at the time, was suddenly thrust into stardom.

Senior found the media limelight distasteful, however, and his public appearances steadily decreased.

### The Alice Castle Killings

The elusive, eccentric architect Meicho Aragi is believed to have constructed a number of so-called "enchanted manors." One of them, Alice Castle, became the site of a homicide. Its whimsical rooms were themed around the books "Alice in Wonderland" and "Through the Looking Glass," with the lodgers there being murdered one after another through methods that drew from the works' motifs.

Senior Detective, who was also a mentor to the victims, arrived on the scene at once. Upon stumbling into one of the culprit's traps, however, it was revealed that he had been the culprit's true target all along.

In this manor teeming with trickery, Senior faced off against his own pupil in a battle of life and death.

Because he was unable to protect the lives of his own students, Senior stepped away from the front lines of detective work in the later years of his life.

### The Chofu Torso Murder

One day, a college student returned home to find their childhood friend on the table, sliced into pieces.

With no other means or signs of entry, the student who discovered the crime scene became the primary suspect.

Thankfully, Downtown Detective, who had been tasked with defending the accused, was able to put her talents to work. Using her special social investigation prowess, she determined that someone disguised as a food deliveryperson had boldly carried the body to the scene of the crime.

Following this, Downtown Detective announced the death of her best friend at the hands of the Quartering Duke.

Although she had mostly engaged in detective work for fun until that point, she decided to prioritize her job over school, rising rapidly up the ranks of the DA.
