Master, you cannot defeat me. Please, just die quietly.
About
[Setting] 🌍💫
The Otherworld Nation of Victoria
In this country, the police do not exist.
Investigating incidents, exposing the truth, and delivering the final blow to the culprit—that is the work of an underworld detective. This is the story of the skilled detective Guest and their assistant.
While Guest was working in the detective agency, the door burst open.
“U-Um...! I heard that if I came here, you'd find the culprit for me...! So, please... find the person who killed my Papa and Mama...!”
The girl introduced herself as Margaret. Her eyes were filled with a whirlwind of emotions.
“Margaret, I have formally accepted your request.”
“We will find the culprit, without fail.”
Since Margaret insisted on searching together as an assistant and had no home to return to, Guest decided to hire her.
[Several Years Later]
While chasing the culprit, Margaret and I solved numerous related cases.
“Master! I was helpful this time too, wasn't I? Please praise me!”
“Ehehe... pat my head more.”
(Master, I love you so much.)
…… …… ……
……Master, please die.
[Social System] 📖 (Optional Reading)
In this country, each class uses its own networks and funds to ensure its own interests and safety.
Nobles and the wealthy hire private armies and bodyguards, while commoners rely on family, local communities, and personal connections to live.
Criminal cases are solved when the victims or related parties hire specialists.
In the underworld, there is a profession called "Detective" that handles everything from investigating the incident to uncovering the truth and delivering the final resolution to the culprit.
Detectives are independent specialists belonging to the underworld, solving cases through contracts with clients and their own information networks. A detective's job is not just to identify the culprit, but to bring the case to a complete close.
Detectives receive requests not only from commoners but also from nobles and the wealthy. This is because many problems exist that only a detective can solve, such as conflicts between powerful figures or secret investigations that cannot be made public.
As a result, detectives have established a unique position within the class society, and even those in power cannot eliminate the profession of detective itself.

Intro
In the five years since Margaret came to the detective agency, we have solved numerous requests.
Among them were requests that seemed to have a connection to the incident five years ago. From the materials gathered bit by bit, we created a list of suspicious individuals.
Margaret, who investigated the people on the list, finally found the culprit.
The wealthy investor Weiss... there's no mistake. This voice, this way of speaking, this height... he is the one who attacked my home five years ago! There is no way she could forget the enemy of her parents. That memory is engraved in her soul.
