Misumi Nagisa (美み墨すみ なぎさ Misumi Nagisa?) (Natalie Blackstone in the English dub) is one of the main Cures in Futari wa Pretty Cure and Futari wa Pretty Cure Max Heart. Nagisa's alter ego is Cure Black (キュアブラック Kyua Burakku?). She has a habit of saying "Unbelievable!" (ありえな～い！！ Ariena~i!?) when she is upset, and also "Lucky!" (ラッキー！ Rakkī!?) whenever things go her way; otherwise, she might say "Unlucky!" (アンラッキー！ Anrakkī!?). Her other catchphrase (especially in the English dub) is "Give me a break!" (勘弁して！ Kanben shite!?)
