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.

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 ...

“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 ...
