B-Sha is a bright, innocent girl who also happens to be a Hero of Justice.
Her hobbies include building robots and collecting as many hero toys as she can. She loves money to an even greater extent, though. She transforms into the mysterious hero known as Presto Mask to fight evil and protect the children. Everyone already knows she's the one behind Presto Mask but entertains her dreams of being a hero anyway.
C-Sha is the most sensible member of Gold Third who also happens to be in charge of it. She's more of a glutton than her looks may suggest, and she can't do so much as lift a finger on an empty stomach. She usually watches over the other three members of Gold Third from afar. In times of need, she exerts excellent decisiveness and judgement on behalf of the group. She's very fastidious about being stylish.
S-Sha is a noble warrior who wields a crystal sword. She's young woman who's reserved and seems very cool, but has a considerably aggravated case of chuunibyou. She has two Dogoo-like monsters who serve under her. She's usually indifferent, and has a habit of saying "not interested" in response to just about everything. That being said, she does, however, show blind and passionate devotion to a certain person.
K-Sha is sleeper mercenary with a fluttering heart and a student of the Lastation school for girls. She excels in both academics and sports, and rumour has it she is quite popular with the boys. Her hobbies are music appreciation and performance, and she's also skilled at rhythm games due to her quick reflexes. Whenever she picks up a gun, however, her personality changes to that of a military veteran. She is then able complete a mission without so much as wincing at the sight of a gruesome bloodbath.
Uzume lives in Zero Dimension, which is also where Neptune and Nepgear first met her. Though she can be pretty blunt or harsh at times, deep down, she has a kind heart. She also bears a strong sense of duty as a CPU. She risks her life in order to protect the residents of Zero Dimension who are barely surviving as it is. Her fighting spirit and devotion to her people is almost unparalleled. On the other hand, her habit of intense daydreaming reveals she has a more girlish side to her beneath the surface.
Orange Heart is Uzume’s HDD form. Her lively and gruff personality completely reverses. She exudes an adorably cheerful temperament in this form. Calling her enemies "doggies" and dancing to the beat of her own drum might make her seem lacking in ardor or urgency during battles, but she is always earnest and ready to fight for her people.
Umio is Uzume's right-hand fish and has the most serious facial expression you've ever seen on a person, fish or not. Contrary to his ridiculous appearance, he has a very sensible personality, and Neptune describes him as an "elegant gentleman." He swims through the air instead of the water, but whether he uses lungs or gills to breathe is shrouded in mystery.
The other Neptune that Nepgear meets in Zero Dimension. Like the smaller Neptune, she has a bright and positive personality. Contrary to her mature look, however, she displays some semblance of innocence or defenselessness in her actions. Her hobby is filling her specimen book, the "Nep-Note," and she travels to other dimensions in search of rare bugs. While she's called the "Older Neptune," it's still unclear whether she's actually an adult or if she's actually still just under aged.
