What are the functions of ronin?

Ronin were masterless samurai in feudal Japan who often took on various roles after losing their lords, such as mercenaries, bodyguards, or even bandits. They could serve other samurai, engage in trade, or pursue personal quests. Some ronin sought to restore their honor or find new masters, while others became wandering warriors, living by their skills and code of bushido. Their existence reflected the social and political upheavals of their time, highlighting themes of loyalty, honor, and survival.
