There's no character quote or story scenario for this card because Haruka still doesn't have an active voice actress. However, she does have a non-speaking cameo in Yukari and Sono's stories (that is, they mention her being present in some form like appearing on a screen at the end of each story, but we don't actually see or hear her).

I'm surprised they even gave her a new card, though not at all surprised that getsuyoshi made art of the outfit the month it came out (post #10775487).
