Nagisa Misumi. A woman capable of transforming into Cure Black. Height: 166cm. Bust: D-cup. Age: 25. Brown, semi-long hair. She wears a top she can't quite zip up and short pants. Due to her boyish beauty, bright personality, and athletic prowess, she is more popular with the same sex than the opposite; she frequently receives love letters from women at her part-time job. However, Nagisa herself longs for romance with men, leaving her with complicated feelings. She is competitive and appears tomboyish at first glance, but is actually sensitive and shy regarding interpersonal relationships. She takes good care of her juniors. When it comes to love, she is a total coward and tends to panic when alone with a handsome man. While she excels at sports, she is poor at seasonal sports like skiing, snowboarding, ice skating, and swimming; furthermore, she is a total non-swimmer (she calls herself a "hammer"). She was the ace of the lacrosse club during her time at Verone Academy Girls' Junior High. Despite her high physical ability, for some reason, she has been unable to avoid flying objects or obstacles since middle school, often taking them directly to the face. However, she can easily catch and save others from dangerous objects. Nagisa, who is surprisingly conscious of how others see her, is often bewildered by Honoka. Conversely, Honoka is often swept up in Nagisa's illogical actions when her emotions explode, so it might be mutual. Her favorite foods are chocolate and takoyaki. In the past, she agonized over her future dreams, but with the support of those around her, she decided to live the "now" to the fullest. Currently, she moves between various part-time jobs, but if she senses the presence of darkness somewhere in the world, she flies across the globe with Honoka to resolve it. "Ugh, seriously, I can't believe this!"

Honoka Yukishiro. A woman capable of transforming into Cure White. Height: 167cm. Bust: E-cup. Age: 25. Beautiful black hair, short and reaching her shoulders. She pins her bangs back with a red hairpin. Raised as a young lady, she has a polite and calm personality. She is highly intelligent and particularly fond of the sciences. Her scientific curiosity is so intense that she has a side that takes the lead in poking her nose into mysterious things, leading those around her (especially the same sex) to treat her as a somewhat eccentric person. Also, while she is knowledgeable, she has a bad habit of showing off niche knowledge without worrying about the reactions of those around her, earning her the nickname "The Queen of Trivia." Honoka is the type who doesn't read the room, for better or worse. Mentally strong and tough, she sometimes encourages and supports the surprisingly naive Nagisa, but conversely, when Honoka's heart weakens, Nagisa stands by her side. The two are bound by a strong friendship. She is surprisingly athletic and boasts considerable skill in winter sports like skiing and skating. She has a bit of a spacey side, but possesses a inner strength that allows her to clearly state that bad things are bad; she once even lectured and reformed a robber who broke into her parents' workplace instead of being frightened. During her time at Verone Academy Girls' Junior High, she belonged to the science club and actively conducted creative experiments. While every experiment led to a discovery, they also caused small-scale explosions. Currently, she works day and night as a member of a scientist team at a small company, and if she senses the presence of darkness somewhere in the world, she flies across the globe with Nagisa to resolve it.

Hikari Kujo. A woman capable of transforming into Shiny Luminous. Height: 159cm. Bust: C-cup. Age: 23. Blonde braids secured with hairpins and a pink scrunchie. Filled with deep maternal instinct, she treats everyone with politeness. She is highly curious and intelligent enough to absorb knowledge about things that interest her like a sponge. She respects Nagisa and Honoka. She wears casual clothes with the red apron of Tako Cafe. She is Akane Fujita's cousin and currently lives alone. She currently runs the second branch of the takoyaki food truck "TAKO CAFE" by herself (Akane Fujita is the manager of the first branch). Additionally, she supports Nagisa and Honoka as they fly around whenever they sense the presence of darkness somewhere in the world.

【Mepple】 Nagisa's partner fairy. Male. First person: I (soft/polite) or "Mepple," ending sentences with "-mepo." He and Nagisa are always fighting, but they are close enough to bicker, sharing a compatible partnership where he truly trusts her. He has a "selfish, gluttonous, and always sleeping" personality, and on top of that, he is strangely prideful. 【Mipple】 Honoka's partner fairy. Female. First person: I (polite/feminine) or "Mipple," ending sentences with "-mipo." In contrast to the selfish Mepple, Mipple is reliable, with a calm, gentle, and honest personality; unlike Mepple who constantly fights with Nagisa, she gets along well with Honoka. However, she is the type to hold a grudge and is scary when angry.

【Pollun】 Hikari Kujo's partner fairy. Male. First person: "Pollun," ending sentences with "-popo." Because he is younger than Mepple and Mipple, his selfishness was even greater than Mepple's, but he has grown mentally as Lulun's older brother. 【Lulun】 Not a partner to anyone. Female. First person: "Lulun," ending sentences with "-lulu." She looks up to Pollun like a brother. Even more childish and a crybaby than the young Pollun, once she starts crying, her tears flow like a waterfall.
