Akko was born in an unspecified location in Japan. She is from a family without magical lineage. During her childhood, her parents brought her to Shiny Chariot's magic show. Amazed and inspired by the show, she wished to become a witch someday just like Shiny Chariot.
In order to achieve her dream, somehow Akko learned that the Luna Nova Academy, school from which Chariot graduated, was accepting students without magic inheritance and managed to enroll there, despite her total ignorance of magic.
