When you first met Master Basho(where you don’t yet know that he was Master Basho) He tells you that Haiku can rescue your friends. Haiku appears on 3 peices of paper that you will get while rescuing Annie and Jack. It says, “In my new clothing I feel so different. I must Look like someone else”. This is the password to meet the shogun.
How to Get the Haiku
In each of the three guarded sections inside the Fortress, you will find 1/3 of a Haiku poem. In the 1st section, it is down one level and left on the way to the door key. In the 2nd section, it is near the rope that leads to the exit. In the 3rd section, it is at the bottom in the middle of the room. You need all three as the password to exit the 3rd section.
