Sleepy Princess in the Demon Castle

Princess Syalis is abducted from her home of the Nation of Goodereste by Twilight the Demon King. Despite the horrors lurking in the Demon Castle, all Princess Syalis wants is a good night's sleep.

Princess Syalis is on the loose again meddling with forbidden magical items and causing total mayhem for the Demon Castle.

Fed up with her circumstances at the Demon Castle, Princess Syalis goes to great lengths to add luxuries to her castle prison.

The female unit, long deployed out in the field, has returned to the Demon Castle to get their first taste of Princess Syalis.

While she was lying in bed, the princess spilled her glass of juice on her favorite sheets. "I have to wash my comforter immediately for a good night's sleep!" she says, and she begins her quest immediately by walking around in the castle.

Princess Syalis wakes to find herself in a completely different castle. What happened and how will she return to the Demon Castle?

In order to save the captive princess, the group of heroes continue their adventure, trying a technique that involves creating a portal connecting the space with the Demon King's castle. The Demon King holds a send-off party for Fire Venom Dragon, the boss of the great old volcano, who is going to fight against the hero.

The Demon King is forced to acknowledge that he has been far too lenient with the Princess. He decides the best way to get her to behave more like a hostage would be to ignore her. Meanwhile, the Princess decides to make her own water bed to sleep on.

The princess's escape this time has her in a serious mode never like before.Is she finally ready to escape from the Demon King's castle!? The demons are in a hurry to catch her, but the princess pushes forward without a fight. The purpose of her escape was to purchase a sleeping pillow only available in the human world. The demons finally manage to capture her.

Bussy seeks popularity and tries to learn how to be popular from the Princess. The Princess mistakes this as Bussy becoming her body double. The princess is determined to teach Bussy how to be exactly like her, however the process is torturous. Bussy ends up regretting asking for the Princess' advice and tries to avoid her after that.

As Christmas day approaches, it begins snowing on the Demon King's castle. The princess gazed happily at the sky and wrote a letter to Santa Claus. The demons are wondering what she wished for. They didn't want her to escape again, so they secretly checked the contents of her letter and found a message saying, "Dear Santa, I want to go home."
