DSC (Detective Shelf Collection)
Each detective has an ID, with a DSC number. Detectives register in what is known as the Detective Library to get their ID (Kyoko only registered recently when the novel begins, so she's the starting rank of 9). The Detective Library contains files on 65,000 detectives, their information made public so that anyone can view them and choose the detective relevant to whatever is bothering them for a case.

The DSC number has three numbers. The first number signifies what their speciallity is, with the second number going into a bit more detail of that speciallity. The last number signifies their rank, for example:

Eigo Amino (Age 35) - DSC 367 - Business crime - Business spies - Rank 7.

Shiita Enbi (Age 28) - DSC 245 - National crime - Terrorism - Rank 5.

Kou Inuzuka (Age 41) - DSC 943 - Murder - Locked room - Rank 3.

Kyoko Kirigiri (Age 13) - DSC 919 - Murder - Impossible crime - Rank 9.

Yui Samidare (Age 16) - DSC 888 - Freedom crime - Kidnapping - Rank 8.

The DSC Detective Library classification goes as follows:

0 - General - General.

1 - Religious crime - Brainwashing, illegal teachings, etc.

2 - National crime - Terrorism, rebellion, destructive action, etc.

3 - Business crime - Fake currency, embezzlement, breach of trust, etc.

4 - Nature crime - Destruction of nature, poaching, illegal disposal, etc.

5 - Technology crime - Illegal access, using the internet to swindle, etc.

6 - Sex industry crime - Prostitution, gambling, etc.

7 - Art crime - Art theft, counterfeit selling, etc.

8 - Freedom crime - Threatening, confinement, kidnapping (acts that take away one's freedom), etc.

9 - Murder - Mugging with murder, murder in locked rooms, etc.

The higher detectives get in rakn, the lower their number becomes. The highest rank is 0 and they are known as zero-class. When their middle number becomes 0, it means that they have mastery over a wide range of topics. in a particular branch, making they double-zero-class. 00 class alone means they are a pretty famous detective and the top of the crime. However, there are also those who become triple-zero-class, making them legends. While the Detective Library has been active for about 15 years, only four people have managed to achieve 000 class.

Sirius Astronomical Observatory Murder Case 1
A young girl awakes on the ground with tears streaming down her face and her right arm handcuffed to a bed. She doesn't remember if she is crying because of a sad incident or because of 'that' dream. She tries to gather her thoughts and remembers that she arrived with 4 other detectives at Sirius Astronomical Observatory to meet a client. A sign that read “Welcome to Delightful Sirius Astronomical Observatory” is crossed out to read “Welcome to Despair Sirius Astronomical Observatory.”

She gradually remembers that her name is Yui Samidare, and that she and the other detectives must have been tricked as the client never showed up, but instead, they ended up in this situation. Samidare frees herself by lifting the bed a little and releasing the chain and goes to examine her surroundings. She spots Kyoko Kirigiri lying unconscious on the ground next to blood-stained hedge clippers and hesitates to go near her.

Samidare finds the other detectives lying on beds; decapitated with their bodies switched around. With a heavy snowstorm outside to prevent anyone from getting in or out, and the fact that only she and Kyoko are alive, Samidare suspects the unconscious girl of killing them. Her suspicions deepen when she spots the key for Samidare's handcuffs in Kyoko's grip.

Kyoko awakens at the sound of the handcuffs click, and after spotting the clippers, slowly reaches out for them. Samidare quickly handcuffs Kyoko's left hand to a chair, afraid of what Kyoko would do with the clippers and confronts Kyoko on her suspicions of her being the murderer. Kyoko denies killing anyone and begins recalling of what she remembers from before the current situation: All five of them were alive and chatting in the hall when a white smoke fills the room. Everyone apart from Kyoko drops to the ground unconscious, and she quickly pretends to be knocked out to see how the events proceed. However, the murderer comes up behind Kyoko and places a cloth drenched in a chemical to make sure she was knocked out for sure. Kyoko recalls how she gripped the culprit's hand before blacking out, which was a mans hand, and concludes that Samidare being the murderer was out of the question.

Samidare then ties Kyoko's other hand to the chair with her hair ribbon and continues to investigate her surroundings to make sure no one else apart from her and Kyoko were in the room.

Samidare thinks through the details of the murder and how they resemble a black letter which was delivered to her a few days ago. Kyoko asks to read it, which Samidare complies with, and announces that this wasn't a normal murder scene, but instead, they were pawns in a game.
