"Ronin" refers to a samurai in feudal Japan who no longer serves a master. This often occurred when a samurai's lord was killed or lost their status, leaving the warrior without a purpose or allegiance. Ronin were known for their skills in combat and often wandered the countryside, sometimes taking on work as mercenaries or bodyguards. The concept of ronin has been popularized in various forms of media, including films, books, and video games. Notable examples include the movie Ronin (1998), which features a group of mercenaries, and the Ronin class in the game Ghost of Tsushima, highlighting the themes of honor and loyalty.
