The missing detective and his assistant
The story continues the world of 'Detective Gentleman.' The former director of the Happiness Detective Agency, Akugyo Souma, goes missing, and Yasogami's assistant, Serina Nanao, goes missing after training at the agency. Yasogami is investigated and enters the office while concealing his identity. His concern for Qingcai intertwined with his work investigating cases across various regions.
The detective organization IDLA
IDLA is a detective organization headquartered in the UK with branches worldwide, with qualifications graded from A to F. At only eighteen years old, Yasogami became the youngest A-rank detective. He excels at reasoning and disguise, often approaching his targets under different identities during investigations.

Case composition

Each case is investigated independently, gradually revealing the characters' pasts and the mysteries running through the entire work.
Investigation and detective points

The timing and accuracy of answers affect case evaluation. Character locations on the map and newly opened locations provide directions for further investigation.
Theme song
