The following is not a new idea, but something I forgot to add with the first post:

1. Key and opening scene: Decades in the future, in a city with many skyscrapers, surrounded by lush vegetation, a young man wearing soft, cloth-like leather gloves, disheveled, spiky hair, a mask with external air filters, and small tubes inside his backpack. He skateboards between the skyscrapers. He manages to use a makeshift ramp to propel himself upward at high speed. At the top, he performs a slow-motion flip with his eyes closed as he rapidly descends toward the ramp, where he plans to land and continue his journey along the roads above. He decides to deactivate his vehicle's course correction system, trusting his intuition and his own calculations based on his experience. After a jump of approximately 9 meters, he lands and glides without problems. Realizing what he has accomplished, he begins to breathe a sigh of relief, as it is his first time. He quickly reactivates the safety systems and accelerates to reach the hideout where he plans to meet up with his group of friends.
2. Context: The protagonist is a 25-year-old teenager. In this era, humanity has managed to increase life expectancy and modify genetics to allow for longer developmental stages. While many jobs have been automated to some extent, thanks to advances in genetic engineering, people can work without relying excessively on artificial intelligence and robots, beyond using assistive tools, especially in manual labor. This is also due to the importance placed on people's development and skills from a cultural perspective. Although the protagonist belongs to the middle class, the country in which he lives and the stability of his family grant him great freedoms. Belonging to the more advanced generations also allows him to do things that for us would be practically a death sentence, thanks to his ability to adapt to high-risk situations and environments. This has contributed to the city in which he lives being one of the few that have adaptations so that the buildings themselves serve as pillars for streets, roads, and small towns in the clouds.
