Suppose Bayushi Hisako is opposing a lone enemy personality. If the enemy player uses ring of fire (or hitsu-do, greater sacrifice, etc) to destroy Hisako, destroying the lone opposing personality as a cost, can Hisako legally target and dishonor that destroyed personality?
Bayushi Hisako vs Ring of Fire
A topic from AEG's L5R CCG Rules forum, copied for Oracle of the Void from a copy of the forum saved in October 2015, so pages it didn't save are missing.

No. When playing actions, costs are paid before effects are activated (see Using abilities). Ring of Fire, Hitsu-do and Greater Sacrifice have a cost of destroying their performing Personality, so she is already dead when Hisako is destroyed by their effect and Hisako's Reaction can not target a Personality who is not in play per Implications of in and out of play: "Cards that are not in play or in a resolution, entering-play or focusing area [...] cannot be targeted".
