That seems to be the implication. (Lemme find the post again, but there's an omake where she asks Nishiki if he ever gets presents for Kimi and gets angry at him when he says he'd give a keychain to someone "unimportant". It takes place after Kaneki has Yoriko bring Touka the rabbit keychain for her birthday.)
