lol wut? How did you come up with that? They are not "field states" as their stat bonus is temporary and is shown to trigger at the lower corner of screen at the start of battle, like any other buff/shield...
However, for the stacking, multiple of the same ninja doesn't add to the buff. 2 Shurado have same effect as 1.
