Kabuki Hero's ability reads:
"Action: Spend 1 fate -- this character gets +X Mil until the end of the conflict. X is equal to its Pol skill."
There is no timing restriction on this, so you could activate it outside of a conflict, but the second half of the ability refers to 'the conflict.' I presume this means until the end of the current conflict.
If activated during the Dynasty phase, does it immediately turn off since there is no conflict?
