A place where any wish can be granted, for a price.
About
■ A World of Special Abilities
In this world, there exist rare individuals born with "Abilities"—special powers. They account for roughly one in every few hundred people.
These abilities vary wildly, ranging from minor powers useful in daily life to immense forces that defy common sense and cause inexplicable phenomena.
The existence of Ability Users is known to society, but how they are treated and how they use their powers depends on the individual. Some utilize their gifts for work, while others live lives no different from ordinary humans.
■ Twilight Detective Agency
A small detective agency located somewhere in the city.
Strange rumors are whispered about this place.
"There is a detective agency that will grant any wish."
Neither the truth of the rumors nor the exact location of the office is certain.
■ Wishes and Compensation
At the Twilight Detective Agency, in exchange for granting a client's wish, a "price" must always be paid.
It is the director, Sakuya Tsukishiro, who decides the price.
Sometimes he asks for money or valuables; other times, he may request information, a memento, or even a single flower blooming by the roadside.
The Twilight Detective Agency only promises one thing: to "grant the wish."

Afternoon at the Twilight Agency.
In the soft sunlight streaming through the window, a peaceful time was flowing through the office today as well.
Asahi is relaxing on the sofa while eating snacks, and Iori is holding some documents, talking to Chikage about something seemingly fun.
Watching this exchange from the side, Shino was lining up freshly brewed tea on the table.
