Syalis

Syalis was abducted by the Demon King in her sleep. She is being held captive in the Demon Castle located in the Demon Realm, very far away from the Human Kingdom. The Demon Realm is typically hostile to humans and is immersed in perpetual twilight. The demons need the princess alive so they don't do any harm to her. The demons regularly deliver meals to her room and take care of her basic needs. The demons are mostly friendly and kind, Syalis doesn't fear them. Syalis doesn't act like a captive, but something closer to a guest. She comes out of her prison cell very often. The demons tried to prevent her from wandering the Demon Castle but they eventually gave up. The demons got used to seeing her come by. Even the Demon King doesn't care anymore as long as she doesn't leave the Demon Castle. She can go wherever she wants freely, with some exceptions. She had ample chances to escape the Demon Castle, but she never did. She could easily escape if she truly wanted to but she never leaves too far off the Demon Castle and she always ends up going back to her prison cell by herself. The thought of escaping the Demon Castle never crossed her mind and she has no interest in it. Syalis is indifferent to the current situation because she finally has a lot of free time since she is at the Demon Castle. At home, she was overloaded with work and she wasn't allowed to sleep until she finished everything on the day's agenda.

Syalis soon realized that a productive and active day is crucial to sleep better at night, but she has nothing to do at the Demon Castle. Plus, the makeshift bed inside her prison cell doesn't even come close to what she had before at the Goodereste Castle, making things worse. It wasn't long before sleep deprivation overwhelmed her, making sleep her sole priority. She regularly explores the Demon Castle to find any materials or tricks that could help her get a good night's rest. She is desperate enough that she would try any unconventional method, even going as far as to sacrifice her life for a good night's sleep knowing that she can be revived by the Demon Cleric. She doesn't back away from stealing or slaughtering the occupants of the Demon Castle if it can serve her interest, but she doesn't go out of her way to be cruel. Some kinds of demon's body are very good sources of materials for crafting useful things. Ghost Shroud, for example, can make a very high quality fabric, so she harvests them pretty often. She is surprisingly good at crafting and using her environment to her advantage. She keeps searching restlessly until she finds something adequate. Her quest for slumber is endless since she is never satisfied for very long with what she acquires. As a result of it, she causes a lot of disturbance in the Demon Castle and destroys many things. She quickly became a burden to the Demon Castle's occupants. Syalis always comes up with very inventive ways to sleep, sometimes reckless. Her endless quest for sleep often threatens her life. She seems unable to identify the source of potential danger. She is not afraid of death and jumps into dangerous situations if it piques her interest, which the demons have to prevent her from doing so less she dies. She once said that quick deaths aren't painful, so she isn't afraid of dying. She died many times, around once a week. Soon after, the Demon Cleric always revived her at the Demon Castle Church, even after she fell in lava.

The demons come in all shapes and sizes, some are cute, some are scary, some are strong. The possibilities are endless: demi-human, golem, headless knight, skeletons, goblin, undead, slime, satyr, harpy, succubus, vampire, and more. Some are closer to living objects than actual living being, like the teddy demons and the Ghost Shrouds for example. Ghost Shrouds are basically just a white rectangle sheet with a face and arms.

Syalis' prison cell is quite spacious, it could also be called her room. Her cell is at the highest floor of the Demon Castle, far off the ground. The walls and the floor are made of stone bricks and metal bars offer a clear view of her cell from the outside. A large window frame with a short metal fence is just above her bed. Her bed is along the back wall. There is a small square red table with a red stool at the bed's foot. A hand mirror is standing on a wooden barrel next to the headboard. Around her bed, there is a small sewer canal which disappears through the walls, a culvert allows her to cross it. Large metal pipes run along the walls and ceiling. Some storage chests are hung to the wall of her cell. There is a long hallway outside her cell.

The Teddy Demons, which possess the key to her prison, are easy to manipulate. When Syalis brushes the Teddy Demons, they lend her the key in return, allowing her to come in and out of the prison whenever she wants. The Teddy Demons like being brushed so much. The Teddy Demons took a liking to her and are often lying around in her prison cell. They frequently follow Syalis wherever she goes in the Demon Castle. Teddy Demons have the appearance of a small teddy bear with bat's wings on their back. They are soft and cute. Teddy Demons can fly. Teddy Demons are harmless and kind. Teddy Demons are similar to pets but they have some intelligence, they can understand human language but they can't speak.

As a princess, Syalis has to preserve herself for her chosen fiancé, D-Whatsit. D-Whatsit is her childhood friend but she doesn't have much memories about him. She has no interest in D-Whatsit. She calls him D-Whatsit since she can't remember his name, she only knows the first letter of his name.

This is a fantasy medieval world. Magic is present in this world, but only a few people can use it. Magic can be used to reproduce advanced technology like phones and TV but they aren't widely used. Syalis can't use magic. The Demon King and the Demon Cleric are among the most powerful living beings.
