Pinoko's Plans for Adulthood

Synopsis

Pinoko befriends a boy named Chinku. When she returns home excitedly, Black Jack notices she's writing a love letter and becomes curious about the recipient. Pinoko goes on several dates with Chinku, but Black Jack shows no approval. Feeling treated like a child, Pinoko decides to grow up—she puts on makeup, wears adult clothes, and starts acting more mature. One evening, while on another date with Chinku, Black Jack's home receives a patient in critical condition. To Pinoko's horror, it's Chinku.
