A long time ago, when people and demons coexisted, not in total harmony of course, a demon king kidnapped a human princess and locked her in his castle. Dispossessed, the princess's subjects thought incessantly of a solution ... until the hero emerges to lead the princess's rescue mission! While waiting for her knight in shining armor, what should an imprisoned princess do? The bat-winged teddy bears are not bad, but their cell is so boring! Then, she will decide to spend the long hours sleeping, if only she could make herself comfortable ... if only she did not suffer from insomnia ...
