Hello, does anyone have a list of requirements to unlock characters in this great game? also, is there a specific tactic that works for Millanor and Yggdra? I am having so much trouble with the Undine and Black rose houses it is not funny.

 

What do you mean by chapter? The game says "warring states period" and I am unsure as to the chapter. Do not worry about spoiling anything as:
1. I do not know japanese so it does not bother me
2. I have played union so I know the main story (not hte side story).
Do not worry about spoiling anything in the story.

EDIT: does anyone know what the red means in a territory? That has always confused me.
