Answer:
2) bushido
Explanation:
The traditional belief that is being expressed in this excerpt is "bushido".
Bushido is basically the samurai code of conduct which translates to "the way of the warrior". According to bushido, samurais must remain loyal to their lords and masters above anything else, valuing honor even more than their lives.
Kansuke makes it clear that he follows bushido by saying, when referring to his master, that "you must follow him wherever he leads, even into death".
