Himitsu no Akko-chan: Umi da! Obake da!! Natsu Matsuri

Taisho's father plans to construct an apartment building on a vacant land he owns behind his own house. The spot is a playing field for the kids in the neighborhood who will fight to keep it as it is.

Akko-chan is a bright and energetic 5th grader in elementary school whose father is a newscaster and mother is a picture-book writer. Akko always cherishes the palm-sized mirror that was given to her by her father and treats it with care. However, the mirror was accidentally broken by her absent-minded mother. On a night where a beautiful full-moon hangs in the sky, Akko-chan buries the mirror pieces in the garden and goes to sleep. She is awakened by a soft and kind voice which belongs to the Queen of the Mirror Kingdom. She sends her gratitiude to Akko-chan for cherishing the mirror with care and offers her a magical compact mirror. Whenever she sings the magical words, Akko-chan will be able to transform into anything she wants.

In the Kagami household, the old Western palm-sized mirror has been passed from from generations to generations. Akko-chan has been taught about the importance of the mirror and when she finally receives it from her mother, she cherishes it with all her might. One day, in the midst of a disturbance made by Taishou and his gang, Akko-chan accidentally broke the mirror. She made a grave and buried the broken pieces in the backyard. That night, Akko-chan was awakened by a flash of light and a kind voice which belongs to the Queen of the Mirror Kingdom. The Queen expresses her gratitude to Akko-chan for valuing the mirror so much and offers her a gift - a magical compact mirror. Whenever Akko-chan sings the magical words, she will transform into anything she wants.
