Since Monkey Punch's manga was published in 1967, I realized when I research that the first anime series and the comics were based on movies and TV shows at the time in the 1960s. So, I've decided to look it up on either the Japanese wikipedia or Lupin Central. Link of their website are down below. You can choose the story you like and I will see what ideas that can be put into a story. Most of stories takes places in the 1960s.
