Kiki is a young witch who has just turned thirteen, and as tradition dictates she must now leave the safety of her home for a year to undergo witch training. One clear night, Kiki takes off with her cat Jiji and her mother's broomstick to start her new life, and finds herself in a town near the ocean - but she's disappointed to find that people aren't nearly as friendly as she'd imagined they'd be. With nowhere to stay and no outstanding magical skills besides flying, Kiki begins to wonder if she's come to the right place; but after returning a pacifier to a customer of a local shop, its owner, Osono, offers her a place to stay. Kiki soon decides that she'll start her own delivery service, and with the help of newfound friends she sets forth on a journey to discover who she is and how to make it on her own.
The setting and the animation style are the most notable similarites between Spirit of Wonder and Kiki's Delivery Service, though I have to point out the feel of exploration and wonder as you continue through the plots of each of these highly enjoyable movies. You can enjoy both of these at any age. :)
