During summer, she wears a blue dress with a lighter blue top over it and white sandals. For winter she wears a light purple buttoned top with a pearl necklace, a long blue skirt, gray stockings, and blue heels.

As Cure Mermaid, her eyes brighten and her hair grows into a curled ocean blue ponytail that has a blue ombre further down. Her bangs are mostly braided to the side with purple streaks, and she has four curled strands. She wears a gold tiara with a pink seashell adorned by a blue gem and a pale blue ribbon. Her pearl earrings have shells hanging from them. Her top is blue, white, and azure with a white and light blue collar held by pink pearls around the neck and in the middle, held by a gold sphere. Her skirt is light blue with pale pink ribbons circling it and a longer dark blue layer with a belt of pale pink pearls. Flowing from the back are two blue ribbons resembling fins. She also wears white arm warmers that extend past her elbows and white and blue knee-length boots.

On her waist is a white bow with a gold sphere in the middle of it. The skirt is thin with pale blue ribbons circling the top layer and pale blue and white bows with spheres matching the brooch on it as well. Underneath are pale blue and light layers, with the last one decorated with bubble-like pearls. Her hair grows longer with a softer color and light pink bubbles decorating it. Her tiara changes to matches the others, with a pearl blue ribbon on the right. She now wears a pearly choker with blue gems and her arm warmers remaining mostly the same. In Royal form the gown gains a massive, pale blue lace ribbon on the back.

In Grand Princess mode, her hair grows longer and her tiara is more ornate. Her choker is now white with a matching bow on it with a blue pearl in the middle. She wears a pale yellow dress with a golden gradient to the bottom of the skirt. Draped around her shoulders is a gold cape with fluffy white lining on the collar. In the middle is a large blue bow with a gold sphere in the center and a layered cravat. Her skirt has a ruffle on each side.

In Halloween mode, Mermaid now wears a full dress with a pale yellow and white top that exposes her collarbone with the pearl accents on the top turning white. On her waist is a yellow flower with two light blue ribbons flowing from it. Her arm warmers are slightly looser and now have an additional ruffle. Her tiara is replaced with three yellow flowers and a thin green vine sticking out.

As an adult shown in episode 50, she succeeded in becoming a marine biologist and wears a white lab coat. Her hair is shown worn in a long braid.


Minami is a sophomore at Noble Academy who is nicknamed as the "Academy's Princess". She has a strong sense of responsibility who can sometimes be strict as well but cares for others like a caring older sister. She dreams of becoming a respectable person who can be useful to others. In episode 9, it is revealed that she is afraid of ghosts.

When she saw Haruka transforming and having problems with a Zetsuborg, she tried to protect Haruka, which resulted in her becoming a Pretty Cure. They then became good friends. 
  • Amanogawa Kirara - Kirara is the first person to call her "Minamin" without adding -san or -sama like the other students, even though Kirara is still not very close with Minami, they do share a friendly relationship. 
  • Tina - Her best friend. She really cares a lot about Minami. When she goes to the resort, they swim together in the sea. During a battle against a Zetsuborg, Tina took a hit for Cure Mermaid that nearly killed her. Mermaid was hoping that Tina would pull through and the Miracle Bubble Dress Up Key appears, healing her and Tina's wounds.
  • Akagi Towa - In episode 25, Towa and Minami started to form a deeper friendship when Minami comes to Towa's aid when she has a nightmare because of her fear of the darkness and the resurfacing of her memories as Twilight. Minami helps her to try and overcome that fear and that she should depend on her friends and the rest of the team. When Shut ambushes the Cures' firework celebration, he sees Towa and recognizes her as Twilight and tries to get rid of her when Minami defends her and tells Shut that she is now Akagi Towa. She precedes to help Cure Scarlet in defeating the Zetsuborg.
  • Ijuin Kimimaro - Minami has known Kimimaro since their childhood. Despite this, she didn't let him get away with ending her friendship with Haruka. After rescuing Kimimaro from Stop & Freeze, she accepted his apology before he departed for England.
  • Kitakaze Asuka - Both Minami and Asuka share a love for the ocean, and they befriend each other quickly. Also, Asuka is the person who has actually helped Minami to reconsider her dream and become a marine biologist.


Transforming into Cure Mermaid for the First Time

While looking over the sea one day, Minami discovers a Dress Up Key that had been washed up on to the shore. When Haruka sees Minami dancing ballet, she becomes inspired and hastily asks her to teach her how to do it. She helps her through the basic steps and tries to makes her more flexible. When Haruka sprains her ankle after trying to perform a new step, Minami comes to her aid and bandages it. Haruka is surprised to find out that Minami is not as perfect as she first thought, and she even thanks Haruka for asking her to teach ballet because no one else had the confidence to do so. When a Zetsuborg attacks, she follows Haruka and witnesses her transforming into Cure Flora. When Flora damages her ankle again after kicking the Zetsuborg, she is about to be attacked before Minami pushes her out of the way. When Flora takes a hit for her, Minami tells Close that it is her duty to protect the students of the academy. Her Dress Up Key reacts to her determination to help others and she receives her Princess Perfume, allowing her to transform into Cure Mermaid. She was able to fight the Zetsuborg off before purifying it with Mermaid Ripple.


A few years after the events of the season, Minami is an adult and is now working as a marine vet.
