1. main character
the princess is not a damsel in distress. I believe she's the main villain of the story, cuz she can defeat anyone (with her position as a hostage that should not be harmed) and super vicious when ot comes to get her beauty sleep. and also cutely innocent most of the time. you just cannot hate her despite everything

2. rpg setting
so the poor demons are just trying to bring balance to the game like world, where they have to kidnap the princess so the hero would go in an adventure to save her, thus fulfilling the game

3. funny
yep, it is funny, I enjoy it so much, if you're looking for something funny to enjoy after a tiring work day, this is for you

Amusing princess

Yep, it's a good manga that I'd recommend to anyone with a sense of humor. This princess just wants to sleep well and will not care at all as to what lengths she has to go to achieve it. This sounds like it'd get boring quickly, but the author is good enough to think up new stuff to ensure it's still amusing even after well over 80 chapters.

When I say she's willing to do anything, I mean anything. Killing, pillaging, anything you can think of and more. She's also damn strong and keeps on escaping no matter how many times they try to hinder her from doing so. As the story goes along, it seems she's the one holding them hostage rather than the other way around and all the demons seemingly starts to think of her as their daughter, haha.

By the way, the universe this story is set in is kinda special, it's a truly rpg-ish setting, people can be resurrected by priests so no matter how many times the mc kills demons, they will come back quickly. She also has a habit of dying in her quest for good sleep and getting resurrected, like sleeping on top of a fluffy poisonous mushroom or going into eternal sleep by slipping into lava(although it's not really eternal since she's resurrected in a short time). The demon king and company aren't actually trying to really conquer the world, it seems more like they're having a blast playing off the typical rpg-like situation, for example, they're not going all out against the hero at all. They're actually trying to help him along and modify things so that he can keep on going, even going to the extent of giving the hero items in chests. If not for them, he'd be dead long ago, haha. Well, the princess keeps on screwing up their hard work, pillaging the items that are supposed to go to the hero or demons and more.

If I had to complain about something, it's the notes we get from the translater. The translation is actually quite good, but the notes are annoying, it's a copy-paste message every chapter about his situation and how he wants donations because of it. Something like that is enough to reduce my enjoyment a fair bit and break my immersion. I get he wants help, nothing wrong with that, but putting the notes in EVERY chapter is just too much, putting them in once every five chapters and preferably in a jpg file rather than inside the chapter so that you have to see it while reading would be way better. Maybe I shouldn't complain since I get to read for free, but it's distracting nonetheless. It's not as if they go away when you pay anyway.

It's great—just as extra fine as the initial concept and the working out of it over multiple chapters. Almost no gag manga I've ever read has gone to anything like this length in drawing the panels. There's elegance in almost every line shown in it.

Contains an adorable princess well-versed in murder, crafting, & good sleep. It's a comedy!

Don't be misled: the cute princess of this series is quite the monster. In her pursuit of comfy, she is literally ruthless. It's quite funny though. Wrote a more detailed review on the series, linked below. I quite like this thing. It's something else.

this is one funny manga the fear these demons have for the princess and the cruelty the princess will commit just for a good night sleep... If your looking for a light hearted manga will lots of laughs I highly recommend this manga.

This is, indeed, about a princess trying to get some sleep despite being held captive in the demon king's castle.

Except... she's amazingly vicious in pursuit of this goal. There's a chapter called "Innocent Villain", and that description captures her perfectly - she's essentially the villain of the series (because all the demons are harmless). But she's also innocent, not in the sense that she doesn't engage in constant gratuitous violence (because she does), but because she never sees anything wrong with her actions.

In conclusion: This is wonderful and unique. Highly recommended. Especially if you dislike the trope of damsels in distress - here, the damsel is in charge, and everyone else is in distress 😛 ...

EDIT: That said, 50+ chapters in, she does mellow out a lot, starts to talk (which she didn't at all in the beginning), and becomes less murderous and more trolling. The story afterwards is still good comedy, but imo doesn't reach the awesomeness of the start.
