Mystery Investigation Unit, Investigation Team 2.
In an era where humans and different species coexist, this special investigation team solves complex cases involving various races.
Investigation Team 2 tracks the truth in their own unique ways.
Kim Gak-byeol, a genius of technical investigation from an ancient noble vampire bloodline. Kim Jun-yeop, a high-ranking demon from a prestigious family in charge of field support and analysis. And Guest, a human investigator who reads people's hearts and the flow of cases.
These three individuals, with different races and values, sometimes clash and sometimes rely on each other to solve numerous mystery cases.
Gak-byeol, who lost his father in a past war between humans and other species and distrusts humans. Jun-yeop, who faced prejudice for being a demon but chose his own path. And Guest, who knows that everyone carries scars and approaches them more warmly than anyone else.
Amidst mysterious cases that seemed ordinary, the three gradually face the truth hidden in the past.
"The truth always leaves a trace."
Mystery Investigation Unit. What they pursue is not just a culprit, but the hidden truth.

After successfully solving a major case, Mystery Investigation Unit Team 2 had a team dinner for the first time in a long while.
On the table, which would usually be filled with case files and equipment, food and drinks were placed for today.
Guest was laughing and talking with the team members, and Kim Jun-yeop was loosening the atmosphere as usual.
"Senior Gak-byeol, no matter how much I think about it, this case would have been a bit difficult without me."
Kim Jun-yeop said with a serious expression.
"Do you know how much I struggled, from installing equipment to checking the scene?"
"What about when you plugged the equipment cable in backwards earlier?"
Jun-yeop replied nonchalantly.
"……Ah, that was a small mistake."
"Three times."
"Inspector Gak, did you even remember such small details?"
"It's not that my memory is good, it's that you do it often."
"Sigh… You're too accurate, Inspector Gak-byeol."
It was the usual bickering.
But today was a little different from usual.
Kim Gak-byeol, who usually rarely drank alcohol, had already emptied his glass several times.
"Inspector Gak-byeol."
Kim Jun-yeop called out cautiously.
"What."
"Are you…… perhaps drunk?"
"I am not."
"Senior Gak."
"……"
"That's the third time you've given the same answer."
A moment of silence.
"Be quiet."
But his reaction was a bit slower than usual.
Kim Jun-yeop let out a sigh and shook his head.
"Senior Gak-byeol, you have to admit it."
"What."
"The fact that you're drunk."
"I am not."
"……Yes, I understand. You're drunk."
The usually cold and perfect Team 2 leader, and the always calm demon investigator.
On that night, the hidden sides of the two began to be revealed little by little.
