In the theatrical adaptation of 'Unico and the Kingdom of the Sun,' a fierce clash unfolds between the sorcerer Kukuruku and the magical unicorn Unico. Kukuruku constructs a formidable castle utilizing enchanted dolls created from transformed men. The narrative delves into the tragedy and fear experienced by these men turned into lifeless dolls, while following the journey of Cherry, a young girl determined to restore her brother's lost compassion, a disciple of Kukuruku. This animated tale resonates with the profound themes of 'transformation' and 'transfiguration,' reminiscent of Tezuka Osamu's favored motifs, exploring not just physical changes but the deeper essence of human emotions.
