Plot
List of Roaring❤Hearts Pretty Cure episodes

The citizens of the magical kingdom of Illuster enjoy a peaceful existence under the watchful eye of the noble Queen Lucinda and her two daughters, Princess Nerissa and Princess Celes, thanks to the magical Rainbow Melody enshrined in the Celestial Citadel's Temple of the Stars, which protects Illuster from outside harm and resonates with the Roaring Sparks - the embodiment of a person’s emotions, dreams, and willpower - its inhabitants carry within their hearts, granting them increased vigor and health. However, these peaceful days are about to come to an abrupt end.

On the day of Nerissa’s 14th birthday celebration, the Rainbow Melody suddenly loses its power. Immediately afterard, an attack is launched from within the castle by the Void Clan, a group that seeks to create a world without will, dreams, or emotion and is led by Sardonyx, a woman who holds a grudge against Illuster for unknown reasons. In the ensuing chaos, the Roaring Sparks of Illuster’s populace are blackened one by one, transforming them into mindless monsters. Before she can succumb to this fate herself, Queen Lucinda orders her daughters, Sirius, head librarian of the royal library, and Amber, bodyguard to the princesses of Illuster, to flee to Earth, along with the Celestial Orgel that once held the Rainbow Melody and the kingdom's four sacred Roaring Medallions, tasking the group with the restoration of the Rainbow Melody and with it, the hearts of Illuster’s people. Unfortunately, the Celestial Orgel, two of the Roaring Medallions and Princess Celes are separated from the group during their escape attempt.

Now stranded on Earth, Nerissa and Amber take on the identities of junior high school students Nanami Nagisa and Kohaku Shishioh in order to blend in with the general populace as they commence their mission to restore the Rainbow Melody and thus save Illuster. Their task is complicated by the presence of the Void Clan, who have followed them to Earth in order to both pursue their own goals and defeat the remnants of Illuster once and for all. Thankfully, Nanami and Kohaku have the ability to fight back this time around by using the Roaring Medallions to transform into the magical warriors Cure Delphinus and Cure Leo. As the two embark on their new lives as both nascent warriors and magical refugees in disguise, they make the acquaintance of the mysterious Hoshikawa twins, Yuu and Tsukiko, who are secretly disguised members of the Void Clan. As the two groups grow closer outside of battle, Yuu and Tsukiko find their hearts gradually opening, something that might lead to their own awakening as heroes.

Pretty Cure
Nanami Nagisa / Princess Nerissa / Cure Delphinus Formally known as Nerissa, the elder of Illuster's two princesses, Nanami assumed her current identity after being forced to take shelter on Earth in the wake of the Void Clan's attack. She is usually quite cheerful and optimistic despite her current circumstances but occasionally uses this cheerfulness as a mask to hide her more negative emotions. Although she takes pride in her status as a princess, Nanami wishes to live like an average girl for the time being, finding her situation to be both novel and a reprieve from the obligations that plague her due to her position. She resents Kohaku's initial insistence on continuing to treat her as her princess, finding her self-effacing behavior painful given the friendship they once shared. After learning the reason behind this behavior, Nanami vows to help her friend regain the confidence her upbringing stole from her. While she resents the Void Clan for their actions, she is a staunch believer in diplomacy and thus tries her best to reach out to them, which has marked results down the line. As Cure Delphinus, the Blossom Knight, her theme colors are pink, fuchsia, and cream, she controls the power of water and she prefers long-range magical attacks.

Kohaku Shishioh / Amber Lowe / Cure Leo Formally known as Amber Lowe, Kohaku is a tomboyish and duty-oriented girl who has been raised from birth by her mother, the captain of Illuster's royal guard, to serve as a bodyguard for Princess Nerissa and Celes. Kohaku initially has little self-worth outside of her role as a bodyguard, and her inability to protect Illuster. along with her loss of the Celestial Orgel, dealt a critical blow to her self-image. Her guilt, coupled with the emotional damage her upbringing inflicted on her, and naturally anxious and self-deprecating, if occasionally rather hard-headed personality leads to her initially pushing herself to atone for her failures by throwing herself headlong into her duties as Nanami's bodyguard. Kohaku only begins to ease off once Nanami helps her recognize her upbringing for the cruelty it was; even then, she struggles to recover from the aftereffects of said upbringing. Unlike Nanami, Kohaku holds a grudge against the Void Clan and is perplexed by Nanami's insistence on treating them kindly. As Cure Leo, the Tempest Knight, her theme colors are orange, yellow, and tan, she controls the power of lightning, and she prefers close-range physical attacks.

Allies
Sirius
 * Voiced By : Mikako Komatsu

Sirius, affectionately nicknamed "Siri" by Nanami, is the head librarian of the royal library of Illuster, the steward of the Temple of the Stars, and one of Illuster's resident long-lived Celestial Beasts. Their normal form is that of a humanoid with dog-like attributes, but they are also capable of assuming the form of a large dog capable of carrying multiple people on their back or more commonly, a smaller version of this form, which is often assumed to be an akita by others. Sirius is usually a calmly cheerful and perpetually unflappable sort, only displaying strong emotions when something is severely amiss. Although they have devoted themselves to helping Pretty Cure in any way they can, they are closest to Nanami, who has known them since the latter was a small child. While their larger form has a fair amount of battle utility, they will only step into fights as a last resort, as they are nowhere near as durable as Pretty Cure is and lack their purification abilities.

Tsubasa Aozora
 * Voiced By  : Mutsumi Tamura

The owner of the coffee shop Shooting Star, which becomes a place of residence for Nanami, Kohaku, and Sirius after their escape from Illuster brings them - rather literally - crashing down on her doorstep. Tsubasa is a rather gruff and overly straightforward older sister type who wastes very little time in adopting Nanami and Kohaku as her younger sister figures and tends to worry about and fixate on protecting them every bit as much as she does her own younger sister, Megumi. She used to be a legendary delinquent leader known as the "Blue Hurricane" back in her high school days, and while she has long since reformed, her old reputation still lingers. The fighting skills Tsubasa honed during her days as a delinquent leader certainly haven’t faded either, and she has no problem fighting back against agents of the Void Clan if absolutely necessary.

Villains
Sardonyx
 * Voiced By : Houko Kuwashima

A bitter and cold-hearted young woman who holds a grudge against Illuster for unknown reasons. She leads an attack on the kingdom at the start of the story, reducing Illuster to a silent and lifeless world populated by empty shells. She is not content to stop there, however, and wishes to rob all worlds of will, dreams, and emotion, as she sees such things as the root cause of her pain. Sardonyx was given the ability to blacken the Roaring Sparks of all living beings within range and transform sapient beings into powerful Utsuroids. However, her gifts are finite, as she discovers after her takeover of Illuster effectively burns them out. In order to restore them and carry out her ultimate goals, she tasks her followers with using Utsuroids to create the negative energy she needs. While Sardonyx is usually standoffish and slow to display affection towards her underlings, she is nevertheless beloved by said underlings, who will do anything to help her realize her goals. Her theme colors are gold and black, she controls the power of fire, and she has a dragon motif.

Princess Celes The energetic, if bratty younger princess of Illuster, Celes is a ten-year-old girl who is gifted with higher than average magical power and seldom seen without her beloved doll, Vulpecula. She was originally supposed to escape to Earth with the other Illuster refugees but was dragged away during the group's escape attempt. Although Celes was believed to have succumbed to the same fate as the rest of Illuster's population, she is later revealed to have survived and become an agent of the Void Clan. She is also responsible for the destruction of the Rainbow Melody, which led to the series' events. Although Sardonyx's gift has greatly amplified Celes' magical potential, she still has the strength and durability of a normal child, leaving her helpless once her magical power is exhausted. Nevertheless, Sardonyx considers Celes a vital component in her plans, namely for her ability to open the Celestial Orgel and manipulate the Rainbow Melody.

Agate / Hisao Hoshikawa
 * Voiced By : Hiroaki Hirata

The eldest of the Void Triad, three siblings who serve as Sardonyx’s enforcers. Agate appears to to be a spacey and carefree young man of twenty-one who is a notoriously heavy sleeper, is not above slacking off mid-fight, and is seldom recognized as anything resembling an authority figure by his younger sisters. While he is easily underestimated by both Pretty Cure and the twins, Agate is both far more competent and much more cynical than he lets on, hiding his depression over and apathy towards Sardonyx's goal, which he self-admittedly has no real interest in fulfilling but feels he has no choice but to pursue, behind his usual cheery slacker facade. When not acting as an agent of the Void Clan, he can often be found hanging around Shooting Star as “Hisao Hoshikawa” and eventually strikes up a friendship with Tsubasa. His theme colors are dark orange and burgundy, he controls the power of earth, and he has a snake motif.

Tourmaline / Yuu Hoshikawa
 * Voiced By : Junko Noda

The middle child of the Void Triad, Tourmaline is a strict-natured and borderline-emotionless fourteen-year-old girl who is utterly obsessed with earning Sardonyx’s approval, even at the potential cost of her well-being or even her life. This makes her quite the contrast to her laid-back elder brother and flighty younger twin sister, both of whom she has taken upon herself to keep in line. She transfers into Sorairo Academy alongside her sister under the alias “Yuu Hoshikawa” in order to keep tabs on Pretty Cure early on. Her lacking social skills and tendency towards brutal honesty keep her socially isolated compared to her twin sister, leading her to frequently seek solace in the company of animals. Although she starts out with nothing but contempt towards humanity, Tourmaline’s cold heart begins to gradually defrost as she forms friendships on Earth, something that causes her no shortage of internal conflict, so fixated is she on pleasing Sardonyx at any cost. Her theme colors are dark blue and green, she controls the power of wind, and she has a peacock motif.

Selenite / Tsukiko Hoshikawa
 * Voiced By : Makiko Ohmoto

The youngest of the Void Triad, Selenite is her twin sister's opposite in many respects. Where Tourmaline is more stoic, driven, and withdrawn, Selenite is more emotional, flighty, and sociable, earning her much more social favor than her twin when she transfers into Sorairo Academy as “Tsukiko Hoshikawa”. Selenite is taken in by the appeals of the human world and the people who live within it far more easily than Tourmaline is. This, combined with her older brother and twin sister's tendency to treat her as someone to protect and keep in line respectively, leads Selenite to rapidly lose interest in carrying out Sardonyx's plans and become increasingly attached to the life of a normal schoolgirl. However, she is reluctant to make this known to her siblings or boss at first, as she greatly values their happiness, especially the happiness of her sister, over her own. Her theme colors are gray and violet, she controls the power of light, and she has a rabbit motif.

Utsuroid

The monsters of the day. They are formed by removing a victim's Roaring Spark and blackening it, causing the victim to transform into an Utsuroid. Each Utsuroid takes a form inspired by an aspect of the victim's personality and has one prime directive - to generate negative energy, both on their own and by affecting the Roaring Sparks of civilians in the area. Brighter Roaring Sparks, which are found in people feeling particularly strong emotions, make for a powerful Utsuroid, leading the Void Triad to single out victims with this quality. However, brighter Roaring Sparks also release more Rainbow Energy upon being purified and returned to normal, making it easier for Pretty Cure to complete their task of restoring the Rainbow Melody.

Civilians
Megumi Aozora Pretty Cure's easily exasperated homeroom teacher and the younger sister of Tsubasa, who refers to her as "Meg". Growing up, Megumi pushed herself to become a model student and ideal daughter in order to keep herself from being negatively compared to her delinquent of an older sister. Despite this, Megumi really does love her older sister and feels ashamed of how she handled their relationship when the two were growing up, even if she tends to express her concern towards Tsubasa through nagging and criticism. Although Megumi and Tsubasa's relationship has improved somewhat in their adulthood, there are still a great deal of misunderstandings hanging between both women at first, impeding their relationship. Although Tsubasa attempts to keep Megumi in the dark about Pretty Cure's identities and true natures early on, she quickly grows suspicious of her older sister's new charges and learns their true identities after episode 7.

Amane Yamaguchi A second-year student at Sorairo Academy and the representative of Class 2-B. Amane is friendly and personable, if occasionally just a bit too clingy for her own good, and is seen as dependable by both her fellow students and adults around her. However, a lifetime spent being compared to her high-achieving older brother has made her a neurotic perfectionist who frequently overextends herself trying to prove herself useful to those around her, falls apart in the face of setbacks, and is constantly measuring herself against the "special" people around her. Amane is the first to reach out - however overzealously - to Nanami and Kohaku after they transfer into Class 2-B. She has a soft spot for kids and dreams of one day writing storybooks for children.
 * Voiced By : Ai Kayano

Yuzuki Himi A third-year student at Sorairo Academy, the president of its student council, and the daughter of the richest family in town. While Yuzuki’s high status, competencies in many fields, and graceful bearing make her a legendary figure among the student body, the same people who idolize her are either too intimidated by her reputation to approach her or more interested in what she can offer them than who she is as a person, leaving her nigh-isolated outside of her girlfriend, Robin and quietly miserable. Her situation elicits strong feelings of empathy in Nanami, who has experienced similar treatment as a princess of Illuster, and the two girls quickly strike up a friendship. She is quite formal, restrained and no-nonsense, making quite the contrast to her girlfriend, but does have a more playful side, which surfaces more often as she integrates into the Cures' social circle. She figures out Pretty Cure’s identities early on and obliquely reveals this during episode 10.
 * Voiced By : Ai Shimizu

Robin Asahina A third-year student at Sorairo Academy and the captain of its fencing team. The half-American Robin possesses an elegant prince-like appearance, which is slightly undermined by her loud and hammy personality, and is known as “the sun” by the student body due to her self-proclaimed mission to brighten the day of every girl that crosses her path, especially if that girl happens to be her girlfriend, Yuzuki. Although Robin appears to be perpetually cheerful, she tends to guilt herself out of displaying negative emotions due to circumstances in her past, even if this acts to her own detriment. She is elated when Kohaku joins the fencing team given her high skill with a sword and is elated to see the initially timid and self-doubting younger girl become more self-confident. Like her girlfriend, she figures out Pretty Cure’s identities early on.
 * Voiced By : Yuuko Sanpei

Irene Asahina A sixth grader at a nearby elementary school and Robin’s younger sister. Once a bright and outgoing girl with no shortage of big dreams, Irene has since withdrawn into herself due to a combination of familial issues and bullying and has become someone who barely emotes, speaks to others, or bothers to attend school, something that causes her older sister no shortage of worry. However, she gets along well with and has little problem talking to animals, making her a valuable asset at the pet store that her aunt manages. She strikes up a friendship with the disguised Tourmaline early on, bonding with the similarly aloof older girl over their mutual love of animals, and becomes key in reforming Tourmaline's twisted heart.

Items
Roaring Compact : Pretty Cure's transformation devices, which resemble small CD players and are powered by a Roaring Medallion featuring the likeness of their respective animal. They are worn in a pouch on the Cure’s waists when transformed and gather the energy released by purified Utsuroids until it can be transferred to the Celestial Orgel. They are activated by inserting a Roaring Medallion, pressing a button on the device, and using the call "Pretty Cure, Roaring Rebirth!"

Melody Arm: Pretty Cure's sidearms, which are able to be summoned once their wielders reach a certain level of power. They possess two modes - an instrument mode, used to execute a powered-up finishing attack, and a weapon mode, used for regular attacks.

Celestial Orgel : The legendary music box that houses the Rainbow Melody. Only members of Illuster's royalty can open it. While it is essentially powerless now, it’s still an object of great importance to the Cures, as their ability to restore their kingdom and return home is contingent on restoring it to its former power.

Roaring Sparks : Shining, star-shaped crystals which lie within all living things and represent their holder's willpower, dreams, and emotion. Removing and blackening an individual's Roaring Spark causes them to transform into an Utsuroid and eventually an empty shell, a fate that befell almost everyone in Illuster at the start of the story.

Trivia

 * Much like the Cures, the villains are also themed after constellations in addition to being themed after various minerals (itself a shout-out to Sailor Moon 's tendency to utilize similar naming schemes for its villains), corresponding to Hydra, Serpens, Pavo, and Lepus, respectively.
 * The (eventual) four Cures in this series also possess an oblique "flower, bird, wind, moon" motif. This is a small homage to Futari wa Precure Splash Star, one of the writers' favorite Precure seasons.
