These original short animated films are screened in the "300 Inch Theater" at Tezuka Osamu World, located in the Kyoto Station Building. The lineup also includes a double feature comprising animated adaptations from among Tezuka Osamu's major manga works, with one film focusing on historic episodes of Kyoto. In this theater, the Phoenix serves as the storyteller, introducing two films. The Phoenix selects a story titled "Old Woman" ("Oba-chan") from numerous episodes of "Black Jack" to explore the theme of how much love can grow within a short lifetime. The narrative features a seemingly greedy old woman who constantly asks her daughter-in-law for money, causing her son and his wife to become fed up with her behavior. Naturally, constant quarrels erupt in the family, and their quiet, ordinary life appears to be lost. After accidentally learning about the family, Black Jack discovers that the old woman had her young son, who was dying at the time, treated and saved by a noted doctor who demanded a large sum of money. In fact, she has been paying for the treatment over several decades. Driven by her great love for her son, the old woman devoted her entire life to settling the debt. Unaware of his mother's sacrifice, the son feels helplessly crushed and squeezed between his mother and his wife. However, when he finally learns the truth, he is deeply moved by his mother's love, which valued her son's life more than her own. Black Jack asks him if he could love her just as much as she loved him. Explaining that only love valued more highly than life can live forever, the Phoenix then tells a story about the move of the capital to Heian, which was a great national project and an attempt to infuse a city with eternal life.
