Napping Princess

Kokone Morikawa experiences a unique sleeping disorder that makes it difficult for her to distinguish between her dreams and reality. In her waking life, she's a typical high school student studying for university entrance exams, but in her dreams, she's a magical princess in a futuristic world called Heartland, where the use of artificial intelligence is banned. This dream world is influenced by her father's past and the secrets he's kept hidden, particularly his work as a skilled mechanic.
