What does it feel like to leave Earth knowing you may never return? *The Last Passenger* is Chapter 1 of Kono Express, an original science-fiction story set in a distant future where interstellar migration has become part of everyday life. A passenger leaves Earth aboard a small shuttle and begins a years-long journey across the Solar System. He passes Mars, travels alongside a massive interstellar ship, experiences life in deep space, and slowly confronts the memories of the life he left behind. After more than two years in transit, the journey finally reaches *Obrion* — a distant low-gravity world of endless oceans, violent storms, and the sprawling water city of **Shionari**. But his arrival is only the end of one journey. Another story is about to begin. *Kono Express* is an original sci-fi world exploring space travel, immigration, memory, artificial intelligence, robotics, everyday life in the future, and what it means to leave one world behind for another. Created through a combination of original concept design, visual development, storytelling, and AI-assisted filmmaking.
