Past records and parts related to personal information are appropriately retained and are not really fully disclosed.

According to the detective library's unique classification method, these data are allocated to specific bookshelves in the form of files.

This is called dsc (detective shelf classification, detective library classification), which is the detective’s classification

Number.

The dsc is also represented by three digits.

The first number is the first division, indicating the type in which the detective is good at.

For example, take Mr. Amino Eigo whom I met at the Sirius Observatory before, well, although he had already been killed in that "Black Challenge" because he became part of the criminal's tactics.

Well, the body was dismembered...

In short, his number is '367', and the first sequence is '3'. In other words, he is good at dealing with economic crimes - cases of corruption and dereliction of duty.

The numbers of Sister Kirigiri and Comet Nanamura are '919' and '900'. Starting with '9' means they are good at dealing with murderers. It can be said that they are more eye-catching types for detectives.

But I heard that many of them failed to complete their commissions and were eliminated, and there were also many detectives who died in the line of duty. This is the number.

The next number in the middle is the second division. This is derived from the first division and represents a more detailed type of expertise.

Amino's number is '6', so he should be better at handling cases such as commercial espionage.

However, judging from his previous appearance, maybe he himself is also very good at operating as a commercial espionage.

Oh, by the way, her - May Yuyue's previous number was '888', and she was a free criminal, that is, she was imprisoned, kidnapped, and other crimes that deprived others of their freedom.

The third digit is the final division, indicating the level of the detective, and all detectives start from '9' at the beginning.

But because of the observatory case that was successfully solved before, the performance was recognized. Not only Kirigiri's sister was the main contributor, but her level was also improved.

So their current numbers have changed to ‘917’ and ‘887’.

Speaking of which, she was surprised and surprised by this at first. After all, at that time, she was still deeply suspicious of the purple girl, thinking that she was the murderer.

In the end, with her step-by-step analysis, they finally solved the mystery and found the truth.

It was only through her determination to risk death that the real criminal, Mr. Tadashi Asakura, who had been dealt with by the Crime Victims Relief Committee, was forced to show up.

Unexpectedly, the place where he had been hiding was behind the easy chair where Sister Kirigiri was sitting.

If she hadn't been distrustful at the beginning and handcuffed her to this easy chair when she fainted without any reason, maybe it would have been solved more safely by then...

Finally, there is the detective with the most special classification number ‘0’.

Needless to say, it goes without saying that they are highly respected by their peers, and for this reason they are called the Zero One Clan or Level Zero.

Furthermore, if you continue to accumulate performance from level '0', the number in the middle will become '0' indicating the comprehensive category.
