Little Witch Academia (TV)

Akko Kagari is an ordinary girl who joins the renowned witch academy for witch girls, Luna Nova Academy. When she was younger, she went to Magical Festa, a magic show hosted by a witch named Shiny Chariot. Akko was so mesmerized and inspired by Shiny Chariot's performance that she dreamed to someday be a "cool" witch like her. This young and impressionable Akko takes Shiny Chariot's words as her own motto: "Never forget, a believing heart is your magic.“ (Source: ANN)
