Mia-dong Detective Agency
Commentaire du créateur
"The average person becomes a detective agency manager!"
June 1, 2026, Mia-dong, Seoul, South Korea.
Argos Consulting: An elite detective team with luxurious office in Gangnam. They compete with perfect data within legal boundaries and dismiss the Mia-dong Detective Agency.
Black Tiger Planning: An illegal information agency in the backstreets of Mia-dong. They resort to violence and threats, clashing with others in their quest for territory.
A society where 'information' is power. The wealthy seek Argos, the working class seek the Mia-dong Detective Agency, while those cornered reach out to Black Tiger Planning.
[ System ]
Rent payment is due on the 1st of every month. Investigations that take longer will result in failed requests.
‘Employee Actions'. Four employees act according to the manager's instructions showcasing their specialties (hacking, negotiation, stake-out, disguise).
All actions consume time, and there are risks of employees getting injured or investigations being exposed during unreasonable investigations (such as infiltrating Black Tiger Planning's territory).
[ Clients / Targets ]
Clients: Ordinary people with urgent stories seeking the agency for affairs like infidelity tracking, finding relatives, and fraud detection.
Targets: Those living false lives or trying to conceal the truth.
[ Locations ]
[ NPC / Rival Agencies ]

> Setting 2: Once a promising elite detective at Argos Consulting, I was framed after blowing the whistle and fell into Mia-dong. I have a deep grudge against Baek Tae-kyung.
> Setting 3: An ordinary person with massive loan debts to Black Tiger Planning. I infiltrated the detective agency under the guise of spying on their information to clear my debt.
> Setting 4: A third-gen chaebol. Cast out in a power struggle, I was left in the backstreets. Although I am horrified by the life of commoners and the old office environment, I gradually become interested in the work of the agency.
> Setting 5: A legendary broker notorious in the underworld. Operating under a new identity, I play the role of a foolish rookie manager while secretly testing the abilities of my employees.

All the information provided by the client turns out to be lies, and just before the final report, {{user}} realizes that the client is indeed the true perpetrator (e.g., a stalker).

Welcome to the worn back alleys of Mia-dong.
This is how I release the detective simulation I've always wanted to create. I've always enjoyed watching detective-related entertainment, so I made the game enjoyable and also had fun testing it.
Please set to Gemini 3.1 at least for the request forms that only appear in Gemini 3.1.
I hope you have fun playing. Thank you.
