Failing in Dreaming
Ever since Erika and her older sister Momoka were small, they dreamed of becoming a charisma model, just like their mother who used to be a famous model. However, Momoka always became the more successful of them, and Erika could only watch in admiration and jealousy when her sister got scouted in elementary school. As Momoka became more popular, Erika slowly began giving up on her dream to become a model, and instead focused on designing, though is still jealous and depressed of Momoka's success where she failed.HPC08
Meeting TsubomiIn the present, Erika is giving the new student Hanasaki Tsubomi a hard time on her first day, though tries to give her a new and better look after school when they realize that they are next-door neighbors. However, she herself has a hard time when she realizes that she will be alone in the fashion club when the other members have to quit, and fails to make Tsubomi join. She takes a walk some time after that, where she meets Sasorina, who takes her Heart Flower. This is what causes her Tsubomi to try becoming a part of Pretty Cure HPC01. After having her Heart Flower purified, she only remembers the events as a dream, and apologizes to Tsubomi for her energetic personality. They then agree that, if Erika can make the doll that her Heart Flower possessed pretty, Tsubomi will join the fashion club.

After school that day, they see that the football-loving girl Ueshima Sayaka's Heart Flower has transformed into a Desertrian and is attacking junior high students. Tsubomi transforms into Cure Blossom, while Erika watches from the sidelines. After seeing Cure Blossom fight for the sake of everyone's Heart Flowers, Erika decides to become a Cure, too, and transforms into Cure Marine. Thanks to the dream beforehand, Cure Marine is easily able to purify the Desertrian. After reverting their transformations, Erika and Tsubomi find the owner of the doll from the day before and give it back. They then decide to work hard together to protect everyone's Heart Flowers and recruit new members for the fashion club while they go to find something to eat.HPC03
Because of Erika's strength as Cure Marine, she is giving Tsubomi low confidence in being Pretty Cure, though Erika misunderstands why Tsubomi is feeling down, and thinks it is because of her still open personality.

On their way home, the girls agree that their friendship have become stronger, and declare themselves best friends.HPC04

Later on school, when Tsubomi shows an admiration for Momoka and asks if they are related, Erika admits their family situation to her. Tsubomi tries to cheer her up by proposing to have their next fashion club meeting outside on the new cafe which Erika agrees on. After school, Erika shows the girls her designs, but they are interrupted when people notice Momoka, who was watching them for a short while. Because they know of their family ties, the fashion club asks Erika to have them watch for Momoka's next photo shots. When she asks her, Erika is forced to let Momoka see through her designs against her will, and although it seems like Momoka likes her designs Erika imagines that she is making fun of her and gets furious at Tsubomi and the rest of the fashion club for having to go through all the embarrassment. The next day, Erika watches in horror as Kumojaki steals her sister's Heart Flower the dahlia, and finds herself unable to fight the Desertrian as its source of power comes from everyone treating her special against her will, something Erika also has done.

Erika asks her if she hates him, and when she denies it she encourages Tsubomi to tell her real feelings so that it is easier for Erika and Obata to understand and help her. Eventually, Erika respects Tsubomi's desire to not have her father work for the company, hearing about her lonely past when her parents, both professionals, worked all the time.

Erika helps Tsubomi to finish the last of the homework before they walk outside, Tsubomi taking her to the place where she met Chypre and Coffret for the first time. Erika jokingly acts jealous when the story is concluded, but is cheered up by Tsubomi's claim that they ended up being best friends, as well. They then look at the horizon, thinking about the Desert Apostles and how many times they have to fight them to defeat them once and for all. After clearing their worries away with the Hart Perfume's turqoise Heart Seed, they meet up with Sayaka, who has started a soccer team on her own. However, at school the day afterward, Erika and Tsubomi find the soccer team injured, claiming it was Pretty Cure who did it. Tsubomi and the fairies try to reason the claim by saying that Cure Moonlight might have come back, but Erika doubts it, as Cure Moonlight would not injure innocent people. They then encounter Dark Cure, the injurer of the soccer club, who overpowers the girls and kidnaps Chypre and Coffret, wanting them to bring her the Heart Pot in exchange.
At the botanic garden, Erika is frustrated that they were defeated to easily, but like Tsubomi, is conflicted about what to do.

Erika (えりか?): Erika the given name is common in Japan, but actually it is an English name "Erica"/"Erika" that many Japanese parents loves to give, and often written in different kanjis without a formal one.

Her name means, "coming sea spring heathers."
Cure Marine: Despite the theme of Heartcatch Pretty Cure! being flowers, marine is a general term relating to the sea, ocean or to oceanography.
