A player, 18 October 2012
If I have won a battle via Aramasu's Legacy and give my opponent a Goju Asuka in my dynasty phase, can my opponent choose the personality 'locked' by my stronghold to satisfy the effect of Asuka?
What if I have given my opponent two Asukas, can he choose the same personality twice?
Aramasu's Legacy: Limited: Create an additional Attack Phase, during which battle resolution does not destroy defending armies or provinces and does not bow your Mantis Clan Magistrates or your attachments. After it ends, if you won any of its battles (even against no units at resolution), you may target a Personality or Holding, bow it, and negate its straightening until after your next Straighten Phase ends.
Goju Asuka: After Asuka enters play: You may give control of her to another player. Asuka may not assign, and will not move, into a defending army. After a Straighten Phase begins: Choose your bowed non-Spider Clan Personality. Negate his straightening this phase.

Yes and yes.
