Here's a protip, loud and clear, for you or anyone else:
USE
DOUBLE
ICHIMONJI
This move is so OP and so much more useful than anything else in the game it's absolutely ridiculous. You simultaneously deal posture damage while recovering your own posture. I honestly can't believe Ichimonji (single and double) is the only combat art in the game that works that way. It renders every other combat art in the game worthless in terms of actual usefulness, especially against bosses.
And here's another protip if you or anyone else is still having issues recovering your own posture:
PUTTING YOUR GUARD UP
MAKES YOU RECOVER
POSTURE MUCH QUICKER
And a last one:
AGAINST BOSSES
USE FIRECRACKERS
BEFORE HEALING
It would be so good if the double ichimonji worked with the last boss second phase
