Misumi Nagisa

Misumi Nagisa (美墨なぎさ Misumi Nagisa) is a woman who appears in Fujimura Aika's dreams. Originally, she used to be one of the antagonists in Futari Wa Pretty Cure Sky Jewel known as Silhouette (シルエット Shiruetto). After being purified, she can turn into Cure Black (キュアブラック Kyua Burakku).

Appearance
Nagisa has short, pale orange hair and brown eyes that she usually wears down. Her casual outfit consists of jeans that reaches to her ankles, a pink shirt with sleeves that reaches to her elbows, and black heels.

As Cure Black, Nagisa's midriff gets covered in black cloth, and the upper part of her top becomes red. Her skirt, gloves and leggings have extra pink ruffle trimmings. There is also now a tiny pink heart in the center of the bow. Her earrings and belt buckle are now gold.

As Silhouette, she wears a long black dress with a dark pink belt, black heels, and long ginger orange hair that reaches to her hips.

Personality
As Nagisa, she is an athletic heroine who is the mother of Fujimura Aika. She is a good woman who has a strong sense of justice, and never lets anyone down. She is still a scatterbrain. Nagisa and her best friend, Yukishiro Honoka, went on a mission to the Dark Zone, but never came back. It was later revealed that they were caught and turned to stone.

As Silhouette, she was a mysterious woman who serves the Dark King and claims to be forever faithful to him. She is known as "The Black Shadow" and is evil. It is later revealed that the Dark King had freed Misumi Nagisa and Yukishiro Honoka from their stone prison, but Nagisa was turned into Silhouette.

Becoming Silhouette
Nagisa was exploring the Dark Zone with her best friend, Yukishiro Honoka. As they gathered enough information and were getting ready to leave, enemies sprang out of nowhere. They were taken to the Dark King, where he turned to duo to stone. When the Dark King heard that Nagisa and Honoka's daughters, Fujimura Aika and Tanaka Masami, had become Pretty Cure years later, he freed Nagisa and Honoka, but he brainwashed them and they assumed the names Silhouette and Witch.

Relationships
Yukishiro Honoka - Nagisa and Honoka are best friends, but after both became brainwashed, they referred to each other as enemies, and they want to see who is the better enemy to Pretty Cure.

Fujimura Aika - Nagisa is the mysterious woman in Aika's dreams. It is later revealed that Nagisa is Aika's mother, and went missing with her best friend on a special mission, but the duo never came back. Aika has made it her lifelong goal to save her mother.

Cure Black
Cure Black (キュアブラック Kyua Burakku) is the Pretty Cure alter ego of Nagisa. She controls the power of thunder. She can transform by saying the phrase, "Dual Aurora Wave!", but she no longer needs Mepple. Her main attack is Black Thunder, which can only be performed in her Forever Form.

Attacks
Black Thunder (ブラックサンダー Burakku Sandā) is Cure Black's main attack, which can only be used with the Black Key inserted into her Earth Light Wand.

Yin Thunder (陰サンダー In Sandā) is Cure Black's second attack, which can only be used with the Yin Key inserted into her Earth Light Wand.

Extreme Heart Sky Jewel (エクストリームハートスカイジュエル Ekusutorīmu Hāto Sukai Jueru) is Cure Black's attack with Cure Sunburst, Cure Moonbeam, Shiny Luminous and Cure White, which can only be used in their Forever Forms, and the Sunset, Glittering Moon, Angel, Yin and Yang Keys inserted into the Cure Sky Sticks, Luminous Heart Baton and Earth Light Wands.

Etymology
Misumi (美墨): Mi (美) translates to "beauty" while Sumi (墨) means "ink".

Nagisa (なぎさ?): A common girl's name in Japanese. While it can be partially translated into many different kanjis, the most common translation as a single kanji is "渚", which means "water's edges; beach; shore".

Therefore, Misumi Nagisa means "beautiful ink shore". This could be a pun because ink is mostly black in colour, which may be referring to her alter ego as Cure Black.

Songs
Nagisa's voice actress, Honno Yoko, has participated in several character songs for the character she voices. Many of them include duets with Imai Asami, Yukana and Tanaka Rie, the voice actresses for Fujimura Aika, Yukishiro Honoka and Kujou Hikari.
