Cirque des Cartes

"To be frank, I hate the circuses. Circuses give cruelty to humans and animals alike, scaring people to their own doom. Also, I bet there's something worse than any other circuses: the Cirque des Cartes. Yeah. These guys seem to be a famous playing card-themed circus group in the Canopy Kingdom, yet the Medici Mafia uses this as a talent pool for hitmen."

The Cirque Des Cartes (French for Circus of Cards) is a famous, playing card themed circus group in the Canopy Kingdom. In reality it is backed by the Medici Mafia and serves as their talent pool for hitmen. However, while most of the performers serves the mafia, some do not or are unaware of its more nefarious deeds.
