Hi there!
Is it correct that a Samurai or Courtier can't Seppuku to reduce a loss from this card? The loss seems to be a totally seperate effect, not even pointing to the owner/controller of the targeted personality, but instead chosing a new target for the loss or gain.
Thank you!

No, that is not correct, if you're referring to the default player ability.
http://rules.l5r.com/CE_The_Player#Player_abilities: "Reaction: Any number of times per turn, before you lose Honor from an action that targeted... by one of your Courtier... Personalities...."
It's an action. It targeted a Courtier. You can use the action.
