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. Players' names are left out; the rules officials are named. Rulings are as they stood on these dates; later rulings, the rulebooks and the Rules Archive may differ.

Battle: Bow a target Weapon attached to your target Personality: Destroy a target enemy Personality with no Weapons, no Armor, and Force lower than the Focus Value plus Force bonus of your Weapon.
I believe this is a new wording for Celestial. Does this mean that, since the "target Personality" bit is before the colon (:), the personality performs Yarijutsu?

Yes, it is a new wording as of CE.
Yes, you are correct that the Personality targeted before the colon performs it.
