Okay, so this came up in a game the other day. I had Chuda Fukuzo xp out in play and a Kakita Noritoshi xp3 in my discard pile. I decided to remove Noritoshi with Fukuzo's Open ability to copy duelist and Noritoshi's ability. Now the question is: would I (with Fukuzo xp) even be able to perform Noritoshi xp3's Iaijutsu Battle ability based on the challange originating from Noritoshi?
Relevant text: Chuda Fukuzo xp Open: Remove a target Personality in any player's discard pile from the game: Fukuzo wears his skin. Until the next time this game this ability is used, Fukuzo copies one keyword, and one ability that does not itself copy abilities, from the Personality.
Kakita Noritoshi xp3 Iaijitsu Battle: Noritoshi challenges a target enemy Personality. Destroy the duel's loser. (Bolded for emphasis)
Thanks!

Yes, because references to Noritoshi in the ability's text are replaced with references to Fukuso.
http://rules.l5r.com/CE_Glossary_C#Copying_abilities:
"References to a source card's own title in the source ability become references, in the copied ability, to the title of the copied ability's own card.
"Example: If Bayushi Ni copies the ability 'Bow San: Ranged 4 Attack' from Yoritomo San, the ability on him is 'Bow Ni: Ranged 4 Attack.'"
