Mahô shôjo Lalabelle

Lalabelle, a 10-year-old witch from the magical land of Biscus, embarks on an adventure alongside her cat Bila as they chase after an evil wizard named Biscus who stole magic items with the intention of making millions. Despite not being able to return home due to their unfamiliar human environment, Lalabelle uses her magical wand and the phrase "Belalulu Belalulu Belalalula" to protect herself and solve various problems on Earth. The earthlings, who were initially saddened by the idea of their granddaughter leaving them behind, eventually decide to adopt her with great happiness, despite her being unaccustomed to human ways and not wishing to hide her magical abilities.
