Anime: Majokko Tickle

Majokko Tickle is an early Magical Girl series created by Go Nagai, airing from 1978 to 1979.

Tiko, a shy Japanese schoolgirl, receives a book as a gift from her father on her eleventh birthday. When Tiko opens the book, she releases Tickle, a mischievous fairy who was imprisoned inside the book for playing pranks on people. Tickle spends the series living with Tiko (having cast a spell so that the family believes she's Tiko's sister), using her powers to solve everyday problems, and of course playing tricks on people, particularly Tiko's annoying kid sister, Hina.
