In an era where both human and demon existed, the demon king had abducted the human princess and confined her in his castle.

She then secretly escaped from her cell in search for a more peaceful place to slumber in the demon king castle while the captive princess does what she wants with the demons as well.

It was announced that Minase will be involved as the main cast as the princess of the human unified kingdom “Kaimin Country” and is known as “Princess Syalis” by its citizens.

【Princess Syalis voice by Minase Inori】

I remembered that I was quite excited when I first heard the title “Sleepy Princess in the Demon Castle” which makes me wonder what type of story is it.
After I read the original, I discover it's about a princess that was abducted by the demon king! A huge pinch! kind of development… or so I thought.
It's a totally different story than what I thought as Princes Syalis kept causing troubles to her surrounding with her recklessness. It was quite interesting!

She gives off an absent-minded atmosphere at first glance but she also off an impression of a tough princess at the same time.
During the audition, I was told to not get too pulled into the quiet atmosphere and raise her elegance and brightness at the same time.
I will do my best on that part so that the animation will be smoother.
