History Characters / SleepyPrincessInTheDemonCastle

* AbhorrentAdmirer: He greatly admires and looks up to the princess as his role model since they were kids and constantly tries to follow her examples, but not only does she not remember his name or face, the only things she recalls about him are the traumatic experiences he caused (in the misguided form of kindness) which leads to her loathing him so much that she'd prefer staying "captive" over ever returning to the kingdom and getting married to him since he's so devoted to her that he doesn't realize how accidentally abusive he can be.

* SpellMyNameWithAnS: Cer and Rus can alternately be translated as "Ker" and "Ros", just like how the original Cerberus can also be spelled as "Kerberos".

* SpellMyNameWithAnS: His Japanese name can alternately be translated as either Hypnos or Morpheus.

* NiceGuy: Despite the fact that she often takes his quills, he always treats the Princess kindly. Because of this, he's one of the first demons she gets close to.
* StraightMan: Besides being annoyed by the Princess' antics, he rarely raises his voice and just wants to live a normal time.

* EnemySummoner: Despite being TheGoomba, they have the ability to summon additional teddy demons to help them in combat. In practice, the one time we actually see them use this ability, it's immediately after the Princess has made herself a set of Teddy Demon themed pajamas out of their fur, so they end up summoning ''her'' into battle by accident.

* MoralityPet: Out of all demons, they're the ones who get hurt by the Pincess the least, and over time she grows a motherly relationship with them.

* {{Chuunibyou}}: He went through something of a "deliquent" phase as an adolescent (going around shirtless, carrying a scythe, etc.) and is deeply embarrassed whenever it comes up. When the Princess visits his family home with some of the other demons he's quite mortified when they discover that his old bedroom is still decorated in an over-the-top macabre fashion with skeletons, spikes, and weapons everywhere.

* HeroismWontPayTheBills: A very rare ([[HarmlessVillain technically]]) villainous example. As the series, and damage by the Princess, goes on, the Elders often find themseves nearly out of budget. Despite incoming threat of humans, Twilight and others still have to find a way to pay their subordinates.

* ForgottenFirstMeeting: It takes the Princess a long time to figure out that her childhood fiance and the Hero are the same person, despite many shared details. The Elders are really not pleased with what they've heard when they connect the dots.

* TropeyComeHome: Between Twilight not giving him any attention, him having to stay back in the castle most of the time there's travel to a human-populated place, and the discovery that [[spoiler:Twilight was once close with Dawner]], a lot of incidents eventually drove him into leaving the castle and [[spoiler:heading back to the yokai troupe he was once part of when he was a pup]].

!!Great Red Syberian

* LordOfTheOcean: He's god of the sea and has many traits which emphasize that, having [[AmazingTechnicolorPopulation turquoise skin and dark-blue hair]] that brings to mind water, is halfway between ApparentlyHumanMerfolk and FishPeople by being mostly human-like but with said odd coloration and EarFins, having the ability to [[MakingASplash manipulate water in various ways]], and his personality is highly temperamental, going from calm and comllected to aggressive and shouting and back frequently, just like the sea can go from calm to stormy and back at a moments notice.

* UnusualEars: His ears have the appearance of fins.

* PeekABangs: From his childhood all the way to the present day, he consistently styles his hair to cover his left eye.

* AmbiguouslyBrown: He has a dark tan skin color, something rather unique among the human-related characters (there are dark-skinned demons, but ethnicity isn't really a thing with them). Given what his name references and the style of his clothing, he's likely the in-story equivalent of Middle-Eastern.

* BareYourMidriff: His regular attire has him completely expose his midriff area, showing off his well-built stomach muscles.

* {{Stripperiffic}}: While his clothing is quite ornate, it doesn't cover much, exposing most of his arms and the sides of his chest, and [[BareYourMidriff leaving his stomach completely bare]].

!!!'''Voiced by''': Takeo Ōtsuka (JP), Kevin Thelwell (EN)

* HornyDevils: She's a succubus, with her having a tail that ends in a heart-shaped tip, a pair of fangs, and tiny bat wings on her head. She's trying to be popular enough to attract people to her to drain their vitality, but she sucks at it.

* AmbiguousDisorder: The Princess often ignores attempts to converse with her, and when she responds she tends to be extremely blunt and literal. She also has much difficulty telling people apart, relying on clothes or very distinct physical characteristics, such as spines or fur, to differentiate between them.

* ExoticEyeDesigns: She has stars in her eyes, which the volume 1 extras state is the mark of the royal family.
* FamilyEyeResemblance: see "Exotic Eye Designs" above.

* ExoticEyeDesigns: Has the same stars in her eyes as her daughter.

* FamilyEyeResemblance: the stars in her eyes are said to be the mark of the royal family.
