Yume Oukoku to Nemureru 100-nin no Oujisama

A young woman from the ordinary world is suddenly summoned to the Kingdom of Dreams, a realm where dreams themselves sustain life. She is told that she is its princess, but there is little time to understand her new position. Creatures known as Dream Eaters are stealing people's dreams, and 100 princes across the kingdom have fallen into an enchanted sleep.

Her unusual power can awaken the sleeping princes, turning a bewildering arrival into a journey across many kingdoms and personalities. Each prince has his own story, loyalties, and troubles, while the spread of the Dream Eaters threatens the world that depends on what they consume. To save the kingdom, the new princess must wake its protectors and discover why she was called there in the first place.
