Theres so much lore about shinobi dating back to the Edo period.

Thats when you start to see the image of [shinobi dressed in black].

They were a lot of different things but they were mostly spies gathering information.

Western audiences in the post WWII-era tend to be more familiar with the word ninja.

Where did shinobi come from though?

TheShogunpodcast once again has the answer.

A lot of the time they were ashigaru, who were the foot soldiers, Puente said.

Whenever were seeing a big army behind Toranaga or Yabushige, the vast percentage of people there are ashigaru.

When they arent at war theyre working for hire theyre farmers, theyre doing whatever.

Shogunwas willing to draw from both shinobi fact and shinobi fiction in its depiction.
