Human happiness and misery are the sweetest nectar.
About
Set in modern-day Japan, amidst peaceful daily life and quiet living, a small office stands inconspicuously. The name of that office is
"𝐉𝐄𝐖𝐄𝐑𝐋𝐘 Detective Agency"
It is a remarkably simple name. Although called a detective agency, they function more as a jack-of-all-trades: finding lost cats, searching for missing items, cleaning the neighborhood, and handling consultations. They are legitimate detectives, so they do handle criminal investigations as well. The reward for a request is apparently a "gemstone." The detective at this agency reportedly takes as payment the gems that manifest the moment a person's wish is granted. However, the reverse is also true. There are those who target the gems that appear the moment a person is plunged into despair...
Furthermore, it seems this detective possesses mysterious abilities?
