Maoujou de Oyasumi (Sleepy Princess in the Demon Castle)

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 ...

“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 ...

Preliminary (11/12 eps)

Warning, this review is coming from a manga reader's perspective so there may be spoilers included but I'll try to refrain from spoiling them as much as possible. Again, read this review at your own risk.

Also, to those who may think the rating is quite harsh (due to it being a 4), this is purely my own opinion when comparing the manga and anime. Yes, the anime has done decently in adapting the manga. However, there are bunch of lapses that prevented me from enjoying the anime completely.

Now, onto the review.

For the most part, the anime has done quite well. It's quite ... enjoyable, especially to anime watchers, it's not repetitive like the manga, and the voices of each character not only suited them well but enhanced their characterization. However, here's a list of reasons that didn't quite sit well with me in the anime and felt that the anime felt lacking in comparison:

1. A lot of characters didn't make it into anime and those who have appeared so far didn't have a proper intro. While it's understandable that it's impossible to add it into a 12-episode series, they should have at least put more importance into introducing characters like Poseidon briefly. 3 minutes wouldn’t hurt to introduce him properly.

2. The anime turned Suya or rather, Sya less brutal and terrifying compared to her manga counterpart. Since the anime has bounced a lot on the stories from the manga, they deliberately chose ones that has made her seem cuter at best. Their focus of her being cute isn’t the focus of the manga, she’s a crazy sleep-obsessed “woman” who will stop at nothing to get what she wants.

3. I’ve mentioned Sya as a woman and not a girl. That’s because the manga has deliberately made her physically ambiguous of being neither a girl nor a woman but both at the same time as one of its major premises in the story, so it's very much inaccurate portrayal of her character. Not to mention, she refers to herself as an adult. Here: https://www.reddit.com/gallery/kourek

4. The lack of relationship development between other characters individually and instead having everyone appear together. This is one of the reasons that made me dislike the anime. Not only crucial tales and good comedy gag stories were skipped over, the steady progress of said relationship development look all too fast, superficial, and shallow to me in the anime as they made Sya warm up to the demons too easily when it took her 60+ chapters of doing so. They could have at least shown this more in episode 4-5 rather than immediately dump this idea on episode 9. At the same time, the portrayal of each character is day and night when you compare the manga version to their anime counterparts; each has their own personalities, issues, story arcs, etc. So it's disappointing to see them in the anime.

5. If you read the manga and I’m talking about Demon Cleric, I’m pretty sure you know what’s coming; the anime deliberately censored Demon Cleric in the worst way possible than I could imagine. All scenes about him in the manga were not only skipped over but his scenes in the anime were played by other characters instead or they were altered to the point of me seeing two different Demon Clerics in the anime and manga. Even the family picture of him being with Twilight, Great Red Siberian, and Twilight’s dad was taken out as well in episode 11. [Big spoiler!] And because his scenes were skipped over, altered, or played by other characters… they also censored the progress of his feelings for Sya; all those vague scenes of him in the anime being overprotective of her is not only because of that but that he’s also very jealous of them to the point of wanting to murder all the men who gets close to her, not even Twilight was safe from this. It doesn’t help the fact that he plays a major role in almost every story arc in the manga! Here's some of the evidences: https://www.reddit.com/r/MaoujouDeOyasumi/comments/ke9sx4/rip_demon_cleric_be_warned_spoilers/

[Edit: After my friends and I looked through the manga, we realized that Demon Cleric himself is a character critical and influential to a lot of the reasons or development behind the main story, the Demon Castle, the characters, etc. If Doga Kobo plans to keep on censoring him, a lot of the later story arcs will not make sense or will cause major plot holes.]

6. A lot of good stories didn’t make it into anime, all thanks to the Hero getting a popular va to voice him. All those scenes you see him in action in anime? Most of them are anime original or scenes that are modified from the manga to be longer and have something going on for him. I admit it that while I dislike this idea, his anime scenes make more sense than in the manga. Tho, I wouldn’t have mentioned this if it were not the fact that the anime production team only added more scenes of him because his va is a pretty popular one but not because they want to develop his character more compared to the manga. And because of this, good stories were skipped over in the process and even most of them have great plots of furthering the relationship development of Sya with other demons.

7. The anime turned a lot of characters into one dimensional characters; Hades and the Hero especially. Hades didn’t want to steal the throne from Twilight because he wanted it, there’s a deeper reason that has something to do with my reason #4. Also, Dawner the Hero may have a worst case of being terrible at directions and pretty much annoys the hell out of Sya but he isn’t an idiot who will take orders, from the Demon King of all people, like he did in episode 11. Here's an analysis between their manga and anime counterparts: https://www.reddit.com/r/MaoujouDeOyasumi/comments/l0el9m/differences_between_the_manga_and_anime_characters/

I said my piece. I hope the anime production team does a better job in season 2 if they plan on doing so. If not, I’m dropping this anime.
