Ronin

The Japanese word 浪人, written in English as Ronin, means "Masterless Samurai" and is composed of the kanji 浪 (read rou) meaning "wave; wandering" and 浪 (read nin) meaning "person" . The kanji literally means "wandering (or wave) person".

Ronin were masterless 侍 Samurai (samurai) though today the English word Ronin implies one who is independent or one that "goes their own way" in the sense of a 一匹狼 Lone Wolf (ippikiookami).
