Sleepy Princess in Demon Castle presents itself a little in the form of a video game anime, where text boxes with options appear, and you get to watch a character decide what they will do. In addition to boxes with action options, the Princess often finds herself on “quests” related to her newest plan for better sleep. From changing out her scratchy pillow with a new luxury one to piping fresh hot water to her new bathtub, the Princess makes her days about looking for better ways to relax and sleep.

The Princess does some unladylike things for the sake of her naps, though. She kills the monsters called “ghost shrouds” because they make the best linens but decides that brushing the teddy bear demons for their fur is more efficient than killing them, especially since they don’t mind giving up the keys to her room when bribed with the hairbrush.

Though the Princess does not seem at all bothered by it, monsters are everywhere! The Princess is the only human in the storyline, but it seems all the characters work for the demon king. Though she is adorable, Sleepy Princess doesn’t care what happens to others in the way of her napping goals. Because of this, the monsters in the castle are frightened of her. Only the rule-loving dog-humanoid is able to scold her, and he restricts her snacks until she behaves. The Demon King is continuously annoyed and frustrated that she does nothing but leave her cell whenever she wants and causes trouble in her wake.

Frequent Resurrection For An Accident-Prone Princess
The Sleepy Princess is arguably a little too fearless in her pursuit of all things nap-related, in that she keeps dying and getting resurrected by the Demon Cleric. After death by slipping and falling into a pit of magma, she dies by sleeping on poisonous mushrooms, and then because she tried to get shock therapy for muscle release from the resident thunder dragon.

If watching the Princess turn into a gravestone every time she dies isn’t funny enough, note that caskets are piling up in her prison cell because she has taken to napping in them for how quiet they are. When the Demon King learns she’s averaging one death a week, he wonders if she is an idiot. Though she was brought to the Demon Castle by force, she has become quite an unwelcome guest.

So far, this story has been about the princess’ quests for all things nap related, but we should not forget that the hero and his team are making their way through the map towards the castle. When he gets there, what will that mean for our Princess? It is also possible that the Demon King is developing feelings for his captive. Every time he goes to talk to the Princess after her escape or property damage, she is asleep, enjoying her next nap. The Demon King cannot make himself wake her and resigns himself to visit another time. What kind of Demon King is he, anyway?

We know we can look forward to the coming anime episodes are more comedic and creative attempts from the Princess! She is always on the lookout to make her stay in the Demon Castle more relaxing and restful. Since the “Female Warriors” have arrived back at the castle, we can expect to get to know them, too. No matter what the season holds, it is bound to be full of laughs!
