One of the descendants could be Giorno. Giorno has his Golden Experience Stand and is quite different from Jonathan in many ways. He's part of the new generation of the Joestar family. Also, Josuke could be among those he meets. Josuke is known for his Crazy Diamond Stand and his strong sense of justice, which he may have inherited in part from Jonathan.
They might have adventures like exploring ancient family secrets. Maybe they discover a hidden Stand ability that has been passed down in the family but lost over time. They could also go on a journey to find a long - lost family heirloom that has special powers related to their Joestar heritage.
Since I don't have full knowledge of this 'An Old Story' by Jonathan Littell, it might be about an old personal experience. Maybe it's about a family story that has been passed down, full of memories, emotions, and lessons from the past. It could also be related to historical events and how they are remembered and told over time.
The main theme is self - realization and the pursuit of excellence. Jonathan, the seagull, is not satisfied with the ordinary life of his flock. He wants to fly higher and faster, which represents the individual's quest for personal growth and breaking free from the limitations of the group.
The JJBA manga is indeed finished. It had a great journey and wrapped up with a satisfying conclusion for fans. However, there's always the possibility of spin-offs or related works in the future.
Well, the main theme in 'Jonathan Livingston Seagull' is about breaking free from the norm. You see, Jonathan doesn't conform to the typical seagull behavior of just scavenging for food. Instead, he is obsessed with flying and perfecting his flying skills. It's like a metaphor for people who want to break away from the daily grind and reach for something greater, something that fulfills them on a deeper level.
The order of JJBA manga is determined by the release dates and the development of the plot. You can start from the earliest published volume and continue in sequence to get the full story experience.
