No, this is not a drama topic, I was just riffling through my world history textbook today and found the word Bushido in the glossary. Apparently it means the following:
Bushido: "The way of the warrior," the strict code by which Japanese samurai were supposed to live.
I don't know if he made his name based on that or if it's just a coincidence, I'm guessing it's the former. Yes I know, useless topic is pretty useless, I just thought it was interesting. There's your fun fact of the day (if you didn't already know it, that is).
