Pearl (Marine)

Pearl, nicknamed Marine by Sean, is a member of the Elementals on ship 9Z5, currently acting as his caretaker.

Appearance
Marine is tall and slender, with a pointy nose, like all the other pearls. Her skin is plain white, and she has shoulder-length light blonde hair going to both sides on the back, with light blue eyes. Her gemstone is located on her navel.

She wears a gray shirt with short and round, puffy sleeves of a lighter hue, and knee-length gray leggings, alongside gray flat shoes.

Personality
One of Marine's tarits that has been explored the most is her overprotectiveness and attachment to Sean; apart from the fact that he is the one she cares about the most and she has been with him for a great part of his life, this also comes from the way she was made. While she wouldn't trade being his caretaker for anything, she still feels like it is a job that binds her, and so, if Sean became independent, she would have no reason to exist whatsoever.

Overall, she is very organized and always tries to make sure Sean is comfortable; as long as she deems it as safe, she gives him support on his interests even if she doesn't understand it, such as when she gave him comic books for his birthday despite not understanding the appeal. Due to their differences in personality and on the way they see Sean, Marine and Olive's personalities tend to clash a lot, which causes them to argue over what's the best choice of action. But even so, Marine still trusts Olive and her strength, thinking she is essential to protect him and caring about her too.

Sean's tendency of risking his life for others, even those who do him harm took a toll on Marine, which made her go as far as to snap and rebuke at him after he woke up when he was attacked by Amazonite. She mostly blames herself for this, believing that she failed as Sean's caretaker and should have done more for him. She also had trouble accepting him fusing with Amazonite to form Turquoise, but eventually accepted them.

History
Her past before the Elementals is unknown, though it's likely that she was kidnapped and rejuvenated by them to work for them. At one point, she was assigned as Sean McCarthy's caretaker and started taking care of him.

Sean McCarthy
Marine is one of Sean's caretakers since he was a young child. Upon meeting her at first, Sean was excited and gave her the nickname of "Marine", after his father told him that in Earth, pearls form in oysters in the oceans. As his caretaker, Marine is very attentious and patient with Sean and constantly worries about his well-being, most of the time excessively, partly because human physiology is an alien concept to her. As the years passed, she became more used to Sean, and cares about him deeply. When he was younger, Sean used to ask her to tell him about his mother a lot, but since Marine was only a servant and didn't know Azurite, she had to sadly decline his offers.

Sean doesn't appreciate the idea of Marine being "just a servant", since he considers her much more than that, and knows that she is able to do great things by herself. Marine can also be overprotective over Sean, such as thinking that he shouldn't be taught how to attack, and instead use his powers just to defend, in fear of him picking fights and getting hurt; this way, even if unintentionally, she gets involved with topics that don't relate to her job, thus "rebelling" from her initial function. Since Marine's assignment as Sean's caretaker is to simply attend to all his needs, she often behaves like a mother-figure to him, by playing with him, chatting, singing to him and telling him stories, and putting him to sleep, which, over the years, made their relationship become even stronger.

In the fourth chapter of Outside the World, Marine worries a lot after Sean is attacked and put in a critical state by Amazonite. Because of this, upon hearing him insisting to go and see her, she lets out all the emotions she had been keeping inside herself and snaps at him, saying that she is tired of seeing him risk his life as it takes a huge toll on her. However, the two apologize to each other and reconcile shortly after, and Marine even agrees to sleep with Sean. She is again concerned and shocked upon seeing Sean fused with Amazonite, and has a hard time accepting everything, but eventually hugs Turquoise.

Agate (Olive)
Olive is Sean's caretaker just like Marine, though she is in charge of teaching him how to fight. As Marine tends to worry too much about Sean, she dislikes the idea of him having to fight as he can get hurt; also, because Olive and Marine have different views on how he should be raised (Marine is very overprotective while Olive is more liberal), their personalities tend to clash, which can lead to them arguing. This is what happens on chapter 2 of Outside the World, and both of them get so overwhelmed that they end up yelling at Sean without thinking, and then apologize to him and each other.As seen by the quote above, Marine trusts Olive and her strength a lot, and trusts her to keep Sean safe from physical threats. It seems that as Sean grew, the two of them became more united, and while still having their differeneces and quarrels, decided to work together to take care of Sean as effectively as possible instead of constantly fighting for dominance, or to replace the other.
