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.

A player, 14 April 2010
Seppun Tashime Exp. reads "Battle: Bow a target unit."
The Last One reads "Open: Target your Personality: Destroy all of your other Personalities. If this destroyed at least four Personalities, permanently give your targeted Personality +4F, and until the end of the game, negate effects of other player's actions that bow, dishonor, move, or destroy him."
If someone has used The Last One on a personality and attached some items/spells to that personality. Would the negation from The Last One prevent everything from bowing or just the personality?

Just the personality.
The Last One's negation only applies to effects on that personality. If an effect would affect more than just the personality (i.e. his unit or another personality) it will still affect those targets, just not the personality that is The Last One.
