Kakita Michihiro reads: Your honorable Artisans at Michihiro's location can not be dishonored.
Deception's Veil Dojo reads: Target another player's Personality. That player may choose to dishonor him (even if he is already dishonorable). If he chooses not to, he loses 3 honor and may ignore Honor Requirements... blah blah...
If I have Michihiro in play, can I make the choice of dishonoring a Personality, or am I forced to lose 3 Honor?
[Mod edit: thread title - please avoid abbreviations like "DVD" for "Deception's Veil Dojo" even if you detail them in your question - LH]

If one of your honorable Artisans at your Kakita Michihiro's location is targeted for the effects of the action on Deception's Veil Dojo, you are allowed to choose to dishonor him. If you do, the effect of Michihiro's trait negates that Stronghold's dishonoring effect on your Artisan (unless the action was played with Determination) and you do not lose 3 Honor.
Effects, Choices: "A choice may be made even if its consequences would be negated or otherwise fail due to lack of suitable things to affect. Example: If a Personality is already bowed, or can not bow due to an effect, you may still make a choice to bow him. If you do not control any unbowed Personalities, you may also make a choice to “bow an unbowed Personality,” which just fails.
