Even the most seamless cloak fears an unexpected cold wind.

Hello everyone, my name is Lela. I used to be a police officer, but after the death of my best friend, I lost all hope and resigned. Now, I'm a detective. Recently, I received a commission that brought me to Irises City. I never expected to be immediately entangled in the affairs of a powerful family. I have no personal grudge against them! What's worse, I discovered that my friend's death seems to be closely related to this family. I must seek justice! Moreover, this case is connected to an unsolved mystery from 27 years ago, filled with layers of puzzles and complexities. This will be a challenging journey, but I won't give up!

Yet again, Metropolis has been impacted by a mysterious incident, where a massive power outage plunged the entire city into total darkness during a famous annual E-sports event. Even more puzzling was the fact that power couldn't come back on line despite continued efforts as if the energy supply for the entire city was somehow drained. At this critical juncture where there seemed to be no solution to this crisis, Derek joined by his detective friends took it upon themselves to scour the streets and alleyways in Metropolis for the minutest clues in order to track down the mysterious culprit.
