Sleepy Princess in the Demon Castle

Sleepy Princess in the Demon Castle

Introduction

The Demon Lord Tasogare's castle is a dark and frightening place, filled to the brim with various monsters. Any soul unfortunate enough to be imprisoned here is sure to be terrified by the horrors within. However, the human princess Aurora Suya Rhys "Syalis" Kaymin is a different case. Rather indifferent to her situation, Syalis worries about one thing and one thing only—sleep. Ever since the demon lord kidnapped her from her kingdom, she has not had a single good night's rest. To alleviate her dozen dozing issues, the princess makes do with what she can find in the castle. Whether it be the fur of fluffy demonic teddy bears or the silky, blanket-like bodies of ghost shrouds, everything is but a means to ensure a peaceful slumber. With so many potential materials to craft items that can help her sleep at her disposal, nothing will stop the sleepy princess—not even death. [Written by MAL Rewrite]

Sleepy Princess in the Demon Castle is, in the nicest way possible, dull. This show doesn't really have any magic that draws you in, causing the viewing experience to generally be mediocre. Every now and then an episode segment is quite entertaining, but this is usually only once per episode. They have a decent cast of side characters that they never use, and the demon/human conflict is poorly built (although it isn't the point of the show so it's fine). This show isn't terrible, but I wouldn't recommend it. Aside from occasional peaks, I was usually pretty bored watching this. There isn't anything unique or special that this show does to draw you in, so it's pretty standard. No clue why it's ranked almost an 8

The rewatch value for this is insanely high. Each episode is so comfy to sit through, and this cozy mood is very consistent throughout; nothing felt out of place. The story is quite simple and straight-forward, and the same can be said for the characters to be honest; this isn't really a detriment to the show, as it is a comedy after all, and the simplistic nature is very much a merit in this case. Each episode can be summed up with the princess trying to achieve the best sleep she can get while causing havoc and mayhem for everyone else in the castle; it fits the wacky trope that she herself is the monster in the situation and not the ones holding her prisoner. Endearing moments are sprinkled throughout, especially within episodes that feature the Demon king and his allies aiding the pr…

Sleepy Princess in the Demon Castle is a masterpiece of our generation. It parodies a common story of a princess being held captive. However, she is unintentionally possibly the scariest being in the castle and what makes the story so brilliant is precisely the contrast between the princess and demons living in the castle. Even though she's basically treating the demons like you would animals and with the demons often looking like such, from the perspective of the demons she is terrifying. Yet because the story is portrayed in quite adorable fashion from the princess's point of view, the differences in perspective are steep and really funny. With the weight of her actions, the princess's nonchalant attitude adds to the comedy perfectly. And all for what? To build a pillow, to find a new b…

This is the most wonderfully, gloriously, amazingly *stupid* anime I have seen in quite a long time, and unlike most times I would say that, that's an unreserved compliment. I haven't laughed that hard since "Kaguya-Sama". The premise is simple: A princess is abducted by the demon lord. But all she wants is a good night's sleep. And she is amazingly resourceful when it comes to finding all the items she needs for said sleep. And make no mistake - no demon is safe when it gets in the way of whatever her current sleep quest is. And this girl is *ruthless*. When I say no demon is safe, I mean it. But one of the weird things about the "demon realm" is that no one - including the princess - truly dies. In spite of her best efforts. All while an incompetent hero is trying to rescue her. In fac…

This is the ultimate casual comfort show. MC is hilarious and the vibe of the whole thing is light, funny, silly, and entertaining. It's slice-of-life comedy about falling asleep. The setting is a demon castle where she finds a bunch of wacky things to help her do so, while inadvertently terrorizing the demon community. She goes from princess to boogeyman over the course of the season. She is like a virus that the poor demons foolishly accepted and now have to live with and cater to. A great anime to watch casually or fall asleep to (the dub is solid for this purpose). Kind of a niche enjoyment for me with its silly fantasy setting and largely middling art style, but I think its vibe would make it appealing to most people.

The show is based off a a relatively consistent premise; that the princess is looking for a good way to sleep. Each episode has a couple different adventures in them, and has a mix of funny and cute often. I started watching not really expecting to go through the whole show, but ended up actually enjoying it a lot more than I thought I would. Honestly, the series was refreshing. It was light on the tropes, and for those that were there, it found a reason for me to give a laugh at (as opposed to them being lazily included for seemingly no purpose, or as a filler) My view of the animation was relatively similar; it was refreshing. There was some repeated frames (cross-episode, not same episode), but I think it was done tastefully. I think that the way this was presented all together wou…

Sleepy Princess in the Demon Castle. "A shoujo anime that's probably a beauty in the beast knockoff." ...is what an idiot would think. Okay, so you've read the Synopsis. What's so interesting about a girl unable to sleep inside of a demon castle? What plot is there even to fit in there? Well to answer the second question... Close to none. However, just because there's hardly a plot to follow, doesn't mean that it isn't interesting. One of the key aspects of this anime is comedy. If you dislike comedy, you may potentially dislike this show. However, this show took the comedy to another level with a completely different atmosphere than the others. Normally, you see a modern society anime, most likely placed in high school. Not only is this show placed in fantasy world, but a princess that…

Fall 2020 was definitely a great season, a ton of great shows span across a wide variety of genres that surely will satisfied anyone. Even so, Maoujou de Oyasumi is still a pleasant and welcoming surprise. An unexpected hilarious anime, bringing fresh airs to the overpopulated genre that is seemingly overflowing with edgy dark and vulgar humor. A prisoner's life is kinda tedious and there's not much thing you can do but sleeping. But thing is a little bit different for princess Sya (I'll call her Sya-hime). Captured by the demon king, as a pro sleeper, she can't bear the terrible bed in the cell. Sya-hime uses her time to make sure she have a good sleep. And not the cell or the demons or even... death can stop her. There's not much to the story itself so Sleeping Princess in the Demon C…

How long do you sleep a day? Well, for most, 8 hours is enough to rest from a long day of activities. For our beloved Princess Suya, 80% of the time is vital to her noble routine. But ... Could an anime like Maoujou de Oyasumi, who has a different idea and highly easy to talk about, overcome any negative criticism? Fortunately, it can be said that yes. When I looked at the anime catalog for that last season of 2020, I was surprised that Maoujou de Oyasumi was on the list. This is due to the anime being adapted by the studio Doga Kobo, one of the best known when it comes to making moe anime, in addition to having a job well done in most cases. It is not for nothing that Anima Yell, Senko-san, Gabriel Dropout and others are known for a charismatic and engaging execution, where the casual be…

'If you got kidnapped and imprisoned by the demons, what should you do?' Well obviously in this situation, you will always try to find a way to escape from their prisoner. But for this anime, Princess Syalis is the most unique one. She rather sleeps in her prison bed despite the panicking situation that is happening in her homeland. :::Story::: But there's one problem! The demons only give her nothing but a low quality bed sheet and pillow. Dissatisfied, Hime-sama decides to go out and create the best quality for her to sleep even if it means murdering demons and destroying useful items. What makes the story even better is not just creating the the best pillow and bed sheet. Each of the episodes have unique plot with variety of quests for Hime-sama to achieve. :::Character::: Many of us…

Maoujou de Oyasumi was a wild ride for me. Watching it weekly was a true joy, and I can't say enough how much I enjoyed this series. Mondays are traditionally the worst day of the week, and for this series to come out every week on a Monday brightened my mood until the next episode. I truly recommend this show to every single person, and while I don't think it holds much meaning or provides much story (and is definitely not bingeable), it is the incarnate of why I watch anime - happiness and escape. Maoujou de Oyasumi follows the story of Princess Aurora Sya Lis Goodereste, a human princess, who is abducted by the Demon King. What follows is not what would traditionally happen, but is a rather light, and ridiculously funny story of the Princess trying to get a good night's rest. The show…

Rhapsody-

“I’m not locked in here with you… You’re locked in here with me!” The tittle is a big lie, don’t get fooled. Maoujou de Oyasumi is not about a moe kidnapped princess trying to get a good sleep. It is not. Of course not. Absolutely not. This is about a psychopath, serial murder going rampage, mercilessly killing and torturing helpless and unaware demons, without any sort of empathy or regret in her big, star-speckled purple eyes. Her cute, harmless appearance and monotonous, expressionless voice don’t stop her from doing the most atrocious actions, from stealing important army stuffs, torturing people under questionable excuses, or emotionally manipulating people with noticeable self-esteem issues… to ripping off bodies to use them as materials, making people explode, flaying alive someone…

Maoujou de Oyasumi (2020) When I saw this at the start of the season I thought it looks nice I will add it to my watch later list. Eventually, due to a quarantine, I had a lot more time on my hands so I watched 11 episodes of this show over the weekend prior to episode 12 and honestly I am so glad I did. It is a really nice, relaxing and great paced show that was a great ride. It even has a nice ending with plenty of Manga to adapt further if possibly wanted. The art style is very much reminiscent of Mairimashita! Iruma-kun in regards to the nice gentle way it shows off demons as fun characters you would love to spend time with. Although some are fearsome monsters they still have a nice feel to them. The main character Sya is especially great when she changes her eyes for shock or horro…

The story begins with the princess getting captured and taken hostage by the demon lord, so it's up to the prince to set off on a journey to rescue her!! … … … Except we aren't watching the prince's journey to rescue the princess. Instead, we watch the princess on her daily quests of tormenting her captors as she attempts to sleep! Every episode, we're treated to a new scheme by the princess as she somewhat accidentally ruins the demon lords plans! From upgrading her bed, to getting better materials for clothes, among other things, there's always another way for the princess to improve her sleep quality, while never even considering trying to escape. If it doesn't relate to sleep, then it's of little importance to her, but as soon as it does, then she will do everything in her power to ge…

The story is very simple. Beginning with a typical hero versus demon intro, in which the princess of the human world is captured by the demons - already setting up the plotline where the hero will save the princess... ...but, what if it never branched off into a typical damsel-in-distress series? Maoujou de Oyasumi manages to literally break all the possible tropes most action series have, while providing a surprisingly wholesome/calming experience for the viewers. Whether you like or hate to sleep, I think this series is a prime example of what upcoming goofy slice of life anime should be like - hence I believe most could easily enjoy this a lot even without having a slight interest in the subject. As I mentioned, the story is very simple. The hero trying to save the princess while the…

Maoujou de Oyasumi was one of Fall 2020’s biggest surprises. Given the fact that DG are one of my favourite studios, it was a given that I would check the show out. I was not expecting it to be this damn good, though. On the surface, the show is pretty basic. Princess gets kidnapped from her country and hero sets out to find her and bring her home. What sets it apart is the fact that the princess actually enjoys her captivity more than being at home, and is constantly looking for ways to improve her sleep. We follow Syallis on her journey to find the perfect night’s rest, and along the way have hilarious interactions with the Demon King and his attendants. It’s really as wholesome as it sounds, but still manages to keep you engaged with its great comedy, character interactions and of cou…

"1001 Ways to Pamper (or get rekted by) a Human Hostage in a Demon Castle" the Animation, feat. the sweet and cunningly-voiced Inori Minase. You know what makes a warm, fuzzly feeling of overflowing goodness in your heart? It's the sweet, tantalizing, emotional feels and cuddly beings that encompasses all that pizzazz, topped up with a batch of light-heartedness with wholesomeness. And Maoujou no Oyasumi (a.k.a Sleepy Princess in the Demon Castle) is just that: a human princess that's been kidnapped by the Demon King, but her only objective of pursuit is to have a good night's sleep, BY HOOK OR BY CROOK. And no, she is not the "damsel in distress" character that even if the hero party comes to her rescue, she doesn't give two hoots about it (heck, forgetting your hero/prince/fiance's name…

As humans, we all have three necessities in life: breathe, eat, and sleep. If you go extended amount of time without any of these three, then death will await you at open doors. However, sleep is a more subjective and everyone gets different amounts. What about the princess of the human kingdom though? How much sleep does Syalis need every day in her life? Those coming into a magical-fantasy story like this should keep your expectations in check. This isn’t some complex tale crafted with deep lore or character study. If it can even be called that, Syalis is a princess that wants nothing more than a perfect, beauty sleep. Or as in her case, Syalis is in love with sleep. She wants to get the most out it and enjoys it as a way of life. Based on the manga of the same name, we got ourselves he…

Tl;dr: A wholesome, fun experience with a good message that bases its comedy on its characters and jabs on the anime fantasy genre. (Light spoilers ahead, but… this is a slice of life-esque fantasy-based anime. Is there really anything to spoil?) “Today was a wonderful and uneventful day” - Princess Aurora Sura Rhys “Syalis” Kaymin. Great anime come in all shapes and forms. Some greats pull off different complex themes that transcend the norm and challenge the viewers to think about its messages and leave the viewer deep into thought after they finish the show. And some other greats masterfully build up their worlds and characters to establish a climax that takes everything we saw from the beginning up to the very ending and leaves us with a nonstop thrilling show from beginning to end.…
