Her actively regretting every line she utters in real-time was great since we've already had a great deal of the "walk away and reflect on your action" scenes already.
I'm not sure who I like better though - Ririchiyo or Karuta. I suppose I can always play the same way the Ice-lady plays and like whoever I can get my hands on at the time.
Ririchiyo seems unnaturally hung up on the fact that Fox might have known she had a fiance.
