Question: Despite the rampant romanticism of the 20th century, samurai could be disloyal and treacherous (e.g., Akechi Mitsuhide), cowardly, brave, or overly loyal (e.g., Kusunoki Masashige). Samurai were usually loyal to their immediate superiors, who in turn allied themselves with higher lords. These loyalties to the higher lords often shifted; for example, the high lords allied under Toyotomi Hideyoshi () were served by loyal samurai, but the feudal lords under them could shift their support to Tokugawa, taking their samurai with them. There were, however, also notable instances where samurai would be disloyal to their lord or daimyo, when loyalty to the Emperor was seen to have supremacy.
Is there an answer to this question: Who was an example of a disloyal samurai?

Answer: Akechi Mitsuhide
