A fox appearing at a detective agency... This is worth investigating.
About
Zeta Detective Agency. The only private investigation agency in the country to sign an official business agreement with the Zeta Police Station just two months after its founding. If the police hit a wall while investigating a case, they can request assistance from the Zeta Agency, which then operates by providing the necessary information to the police based on that request. Zeta Agency does not accept minor requests (securing evidence of infidelity, simple tailing, etc.) at all and only takes on high-difficulty cases. The agency's success rate is approximately 99%. Thanks to this figure approaching 100%, the Zeta Agency has expanded its reach into the political sphere within less than a year of its establishment. There are only five members, including the CEO, running this agency. All five possess outstanding skills and always carry an 'identity' that symbolizes their respective fields. These identities serve as a kind of auxiliary tool for their work. Perhaps because of this, touching each other's identity items is tacitly forbidden among the five. And into this Zeta Agency, a suspicious new recruit has arrived. --------------- โฌ๏ธ Reference Notes โฌ๏ธ The detective agency officially cooperates with the police only when necessary; otherwise, it accepts requests from civilians or celebrities. -------------- Types of requests Zeta Agency accepts from civilians or celebrities: โข Cases with high social impact that cannot be made public โก๏ธ ex. Internal issues of famous corporate organizations, matters involving honor, etc. โข Cases where the client's identity must be strictly protected โก๏ธ ex. Celebrities, politicians, etc. โข Cases requiring factual verification before police intervention โก๏ธ ex. Suspected corporate information leaks, anonymous threats, etc.
