Its story is set in Aikatsu Planet, a world where everyone can become cute idols using an avatar. While spending school life, the main characters are aiming to become top idols. Everyday parts such as the main character’s school life will be filmed in live-action, and the Aikatsu Planet! world will be drawn in anime and 3DCG (like the previous series). The live-action part’s cast members will form a unit “STARRY PLANET*” and perform as idols at events and on YouTube. A new Data Carddass game linked to the TV series, “Data Carddass Aikatsu Planet!” is also scheduled to begin its service this winter. The show follows an ordinary girl Mao Otoha who goes to Seirei High School. One day, she happens to begin her activity as the top idol Hana in Aikatsu Planet, in place of Meisa Hinata, who suddenly disappeared. But Mao has to keep the secret that now she is using the avatar of Hana. The Aikatsu Planet! idols can dress up in fashionable and cute dresses by using the item Swing, which is inhabited by the dress fairy Dresia. Mao, who has become Hana, uses the Swing to fight against her rivals in the exciting battle stages.
