Pssst! Princess Syalis tries to sleep well. A long time ago, when humans and demons coexisted, of course not in complete harmony, a demon king kidnapped a human princess and locked her in his castle. Dispossessed, the princess's subjects thought of a solution ... until the hero shows up to lead the princess's rescue mission!
What should an imprisoned princess do while she waits for her knight in shining armor? The bat wing teddy bears aren't bad, but their cell is very boring! Then she will decide to spend the long hours sleeping, if only she could be comfortable ... if only she doesn't have insomnia ...
