Callisto (or "Kiki" to her friends) is the captain of a small cargo ship sailing through the solar system usually carrying illegal weapons. Regardless of her shady business she's a very cheery personality and is often found singing to herself. She's addicted to coffee and buying clothes.

Callisto is usually very easygoing, optimistic and easily excitable. She's a cheery personality, and thanks to this she gets along with everyone and has a lot of friends. Despite her childishly excited outlook on life, Callisto is actually very mature and even reserved from time to time, especially with trusting new people or before jumping into anything new. She doesn't like making mistakes or looking weak in others' eyes, and she wants to always appear 100% confident in her every decision. When Callisto has decided something, no one can change her mind.

Being very good with people, Callisto is also very skilled at manipulating them. She's a good salesman and stellar at saying just the right things to get people to do what she wants them to. Callisto doesn't really like this, but she does what she has to. A thing that she enjoys, however, is flirting with strangers, but only flirting - Callisto hasn't been in a real relationship in ages and is not planning to change that anytime soon.

Callisto doesn't like showing emotion or talking about her feelings - she'd much rather listen to her friends' problems and help them than open up about her own experiences. Because she likes being so peppy and cheery in social situations, she tends to bottle up anything negative and just cry alone at night, fearing that she'd appear weak if she let anyone know about her problems.

The job of the captain of a spaceship tends to cause a lot of overtime work, so Callisto often skips on sleep, which results to her being chronically sleepy. To combat this she drinks coffee throughout the day in large doses. She's not too experienced in different types of coffee drinks and just likes drinking whatever's the strongest. Callisto hates cleaning and tends to leave her stuff lying around.

Callisto loves trying out new looks and hairstyles. Her outfits always include plenty of jewellery and accessories.

Callisto works as the captain and main pilot of a small cargo ship. Most of the time the ship's cargo includes illegal weapons.

She doesn't really like being called captain and prefers not to stay above her crewmates. However, even if she doesn't like it, she is a natural leader. Callisto likes being democratic and transparent in decision making, but she herself always has the last word. - the only reason she offered to take the captain's title was because the ship's owner Evren asked her to.

Callisto has actually lots of experience on flying all kinds of spaceships so she does most of the flying by herself.

Callisto was born on Earth in a poor nation that had recently suffered heavy casualties in a civil war. Her parents, who dreamed of moving to the peaceful outer solar system colonies, named Callisto after the beautiful Jovian moon. When they died, Callisto was left to take care of herself at a young age. She worked as a pilot for the Earth-Moon trade route for years, saving up money, until she met June who offered her a job as a pilot for a weapon smuggling ring. Callisto, who desperately wanted to see the solar system, gladly took the job despite the shady contents of it and hasn't regretted her decision.
