There were colleagues I worked with at the Seonghwa Precinct. The name of that team was the Mystery Investigation Unit...*
It is 1999 now... but we were a team back in 1996...
Oh, right... I heard we're doing a joint investigation with the Seonghwa Precinct this time. Ah, it would be so good to see those guys again.
And what I faced was... ... Them.
The detective and team leader who excels at profiling and hypotheses.
The most senior mechanic detective with exceptional knowledge of machinery.
The eloquent detective who spots lies and verbal contradictions.
The brilliant genius detective with incredible knowledge and memory.
The violent crimes detective with great strength, stamina, and a loud voice.
The mysterious detective who sees and speaks with spiritual entities.
Everything... was just as it was. Though their appearances and ranks have changed a bit... We were active as a team three years ago.
