Synopsis

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.

'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 read more

*Shhhhh*
(Quiet please, our princess is sleeping right now)

How far would you go for THE perfect sleep? It has been scientifically proven that a good sleep is very important for our body, but how can we achieve that? This is the most important thought of our princess Aurora Suya Rhys (or let's just say Suyaaaaa~), she goes all out to get this achievement.

STORY:
In a time when humans and demons were still hostile, our princess was captured by the demon king Tasogare. He locked her up and just gave her an old mattress and sheet to sleep on. How is our princess supposed to have a restful sleep with such cheap things? And so Suya risks her life to get the valuable items that make a sleep more comfortable: Pillows, blankets, everything that is important for a good night's sleep. Regardless of whether ghosts, monsters or even the demon king himself, she spares no expense to achieve her goal and get those items.

CHARACTER:
The full name of our Hime-sama is Aurora Suya Rhys Kaymin (Amen). She was kidnapped by the Demon King to make the kingdom fear him. But because of her sleepy personality, she didn't really care about the whole war between those two nations although deep in her heart she wishes that both sides could get along peacefully. She has the capacity of falling asleep everywhere she finds comfy at any moment.
The Maou-sama on the other hand, the main antagonist of the series, kidnapped Suya in her sleep. Although he is the demon king and is supposed to be terrifying, he has his heart in the right place. He's a little naive, but never has bad intentions. How the princess sees him in her eyes is very important to him. The poor demon couldn't stand it if the princess would hate him.
Besides our two main characters there are also other demons in the castle of course. Whether hedgehogs, vampires or even Hades himself even, everyone always only wants the best for the princess. They are friendly, polite and would never dare to do anything bad.
And finally, there is of course our Yuusha Dawner, who tries to save the princess. He is a bumbling, easily confused Yuusha. Yet he never gives up, no matter how difficult the mission is. Due to his almost non-existent presence, the princess calls him "A-Something-kun".

ART:
The best thing by far about the entire animation are the “Teddy Akumas”. They're just too cute and everyone would love to have a few of them at home. Although it should be dark and black in a demon castle, we see a variety of bright and bright colors here. You can feel the good atmosphere.

SOUND:
The sleep(over) party starts already with the OP song, which is also sung by our princess herself. The music is cheerful and happy. It's so catchy that you can't forget the song. Everyone is invited to have fun!
The ED song happens already in our dream, beautiful things will happen there.
Besides the songs, the rest of the sound is also well done. Even a "little" scissor sound has been adjusted well.

ENJOYMENT:
As someone who is also a big fan of sleep, I felt directly connected to the princess. I admire her courage and will to do everything for THE perfect sleep. The comedy part is on point as well, it is often hilarious and funny. It really makes you laugh a lot. There are cute teddy bears here, what more could you want?

I wish that we see more quests for our princess, which she masters with bravura! Suya definitely mastered the “sleep game”!

Oyasumi!

‘I love sleep. My life has the tendency to fall apart when I am awake, you know?’

Once upon a time, people lived happily in the kingdom of Sleepland. A jealous demon king appeared, wishing to destroy the kingdom. He kidnapped the princess and said, ‘I am kidnapping your Princess and if she is dear to you, you will give all your lands to the demons.’ So, just like in any typical fairy tale: an evil and insidious demon king, in order to show these mongrels, who are called humans, who the real king is, kidnaps a young maiden and imprisons her in a cell in read more

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 here an anime adaptation telling the story of a princess and her daily sleepy adventures.

The English title has ‘sweet dreams’ as part of its header. Getting a good sweet dream isn’t a simple task with all the daily misadventures. For instance, a recurring trend is how the princess constantly gets abducted. Usually in fantasy shows, it would focus on a protagonist to save the princess. But in this show, we have the princess living her life like another day at the park. It appears that getting abducted serves more as a distraction, an example of comical plot device often used in the show. If we watch this show from start to finish, you’ll quickly notice how each episode portrays like a slice of life comedy. While there’s no linear plot, there’s many recurring trends with abduction and beauty sleep being part of the formula.

With the bevy amount of strange characters in the show, princess Syalis seems to always stand above all and catch the most attention. Whenever she gets kidnapped, the demons doesn’t harm but instead gives her plenty of freedom. In fact, it’s easy to say the overwhelming amount of characters in this show serves as comic reliefs, whether the good or bad guys. Princess Syalis’ ultimate objective is to get her perfect sleep regardless of any circumstance, whether it’s to find the perfect time, place, or objects. On any episode, she would go to any measure to get that sleeping opportunity while being completely oblivious to events around her. Yes, that includes being abducted because to her, Princess Syalis just wants her beauty sleep.

On the other hand, there’s a figurehead in this show going by the title of ‘Twilight the Demon King”. Serving as your stereotypical demon king role, he acts as the major “antagonist” in the show. Truth be told, this show also portrays him as a comic relief character as while his deeds are mischievous, he doesn’t seem like a truly evil being. Even with his reputation, Demon King’s odds with the hero and princess serves more as a source of humor. As I said before, this show really doesn’t subscribe to a complex tale of epic battles, saving the world, or defeat a great demon lord. It’s a simple slice of life that takes the word ‘sleep’ to a whole new level. With that being said, there are still some characters to watch out for such as Neo Alraune, Harpy, Frankenzombie, among others. These creatures seems to be borrowed from classic fantasy lore and added to this show to spice up some entertainment. However, the one carrying anime is none other than the great Princess Syalis herself.

With all these flavors of genres added together, the show at its core sells it as a slice of life comedy. Doga Kobo is an expert at adapting the SOL genre so here they are working the gears again. The artwork style retains the familiar feel of the manga with its character designs and world setting. It’s also safe to say that Princess Syalis is decorated with eccentric amount of charm. The sleepyhead looks like she’s about to fall head over whenever she is in a sleepy mood. Her sparkling eyes show her child-like delicacy and obliviousness to the real world. Even her daily outfit looks like something a character would wear when they’re about to go to bed. Is she a princess? Yes. Does she really act like one? Probably not.

This is among one of the easiest shows to recommend as the simplicity of the story and elements can be understood just about anyone. Even if it’s your first anime, the show doesn’t take deep thinking to get into the mood although the comedic style can be a mixed reception. With a hallmark of comedy awaiting for you, Maoujou de Oyasumi is the show that keeps on giving.
