I want an AU where Kiki’s Delivery Service and Howl’s Moving Castle exist in the same world. I imagine Kiki and Markl could be similar ages, meet, and become friends and magical colleagues as they grow up. Maybe Markl even moves to the town Kiki lives in on the ocean as a part of his wizard apprenticeship (if it works that way) and they meet that way.
1. Markl meets Kiki, “Next time you stop by the bakery, let me know. I have a delivery service that might help!”
2. Kiki meets Calcifer, “He’s the fire demon my mentor gave me to travel with!”
