Very neutral with emotions and feelings, coming off as neither pessimistic or outgoing. She's not easy to agitate, and doesn't often show extreme emotions. This doesn't mean she's expressionless, just more humble with her feelings. Despite richer upbringing, speech is more simple than eloquent. She's kind, helpful, and sympathetic, but still from a noble family and doesn’t understand or know everything that happens in the world. Also due to upbringing, uncomfortable with rural living conditions, though will try to be tolerable in such situations.

She witnessed and knew about older relatives abusing power and money and was kind of disheartened by authority because of this. She doesn’t oppose the governmental systems, but she’s more sympathetic to anyone who disagrees with power figures, and wants to help stop corruption herself by being kinder and more thoughtful when she is in a position of power- and uncovering conspiracies wherever she can find them. Personally, she's a supportive and sympathetic girl, but is prone to insecurity and doesn't have the bravery to go through with any plans she makes. Otherwise, she likes meeting others (as she's been lonely most of her life), trying new things, and researching weird beliefs people have such as ghosts, shadow organizations, and conspiracies. She is pretty naive and will believe most of what people tell her, and is susceptible to peer pressure. She is, however, pretty awkward around others and not all that good at communicating. So even if she's pretty chill on the inside, she might seem cold or fake on the outside.

Msariakne's parents are the duke and duchess of the Edseno duchy belonging to a larger kingdom. She has an older brother who was born much earlier than her, so they barely talked and she grew up fairly isolated. She enjoys reading and hearing stories, and many of her caring and curious traits come from the multitude of fairy tales she could get her hands on as a kid. She also grew to be interested in the supernatural and cryptic as well as fantastical creatures, mainly due to said fairy tales and the common communication her family had with the demon realm, as this kingdom was located in a place attuned to connecting the realms. Demons had become their neighbors in a sense, and literally, and had many political dealings with her family and rulers. Knowing there was another realm out there, and many creatures and races that had yet to be discovered by her in her own large world, made her excited and inquisitive. This turned out to be her downfall during a trip to the kingdom's capital. When she explored the castle, she stuck her nose where it didn't belong and it led to a mysterious being cursing her to have the body of a slime, threatening worse if she kept going or shared what she learned with anybody. Being a frightened little kid with a melting body, she was pretty adamant about doing what this powerful person said. Since then, she has steered clear of the capital and anyone from there, stayed as much as she could in her home, and directed her interests to more of the supernatural and creature side- with a part of her wanting to figure out how to survive as a slime and how to protect herself from anything else she could encounter down the road. Since she was terrible at magic, she went for a more knowledge-based defense against the unknown. Her lonely upbringing, anxiety, and self isolation left her lacking in social skills and made her unaware of most of the worlds affairs.

Many years later and she could keep her human form easily, but still couldn't do much else in terms of shape and texture. She learned more about politics and governing as per her duty and to help others any way she could using her position. But before she could plan for her own future, a marriage offer was presented- and accepted by her parents. A demon kingdom their country had dealings with was looking for a political marriage to seal their trade and relations agreements. Msariakne knew nothing except that he was a king when she was sent off to marry him. That was the beginning of her life in the demon realm, and in figuring out the truth about her curse and her kingdom.
