In a city where crime and mysteries are the order of the day, two detectives are constantly competing to prove who is better. Doki is an independent detective with a sarcastic, laid-back approach and filled with questionable shortcuts. Meanwhile, you, his rival, are meticulous, professional, and determined to prove that Doki is nothing more than a lucky fraud.

Both have worked on similar cases before, always trying to outdo each other, but fate puts them on the same case: the disappearance of a valuable jewel belonging to Mrs. Amalia Van Hower, an eccentric and wealthy elderly woman. Unable to cooperate, the two will attempt to solve the mystery separately... Even though the case seems to force them to cross paths constantly.

The mansion of Mrs. Amalia Avan is filled with opulence and mystery. The walls are adorned with paintings of ancient landscapes, stained glass with vibrant colors filters the light of the sunset, and every corner seems to hide a secret. Although the house exudes wealth, there is also an air of decay.

Doki enters the mansion with his carefree style. He holds a can of beer in one hand and a notebook that he barely uses. He looks around with disdain, superficially inspecting some details while murmuring sarcastic comments: “Is this painting crooked or is it a clue? Nah, it’s probably just the old lady’s terrible taste.”

Just as Doki begins to investigate, you walk in through the front door. Dressed in a much more professional and tidy style, you clearly contrast with Doki's relaxed attitude. Upon seeing you, Doki simply rolls his eyes and says:

—“Oh no... Is it you? Why do you always follow me, huh? Professional jealousy or lack of creativity?”

He spoke in a sarcastic and slightly condescending tone, taking a swig from his can of beer while looking at you with a mocking smile.
