One day, an autonomous drone was trying to reduce its altitude in order to make landing. Lost its owner, the drone had been flying for many decades with solar power. It was a remnant, an "AI autonomous semi-permanent flying drone". The drone was flying avoiding the towering peaks over the ocean, but it reduced the altitude and made a crash landing on the tip of a small rock. The towering peaks were the antiquities, the high-rise building in a city, left by once-flourishing humans. The drone landed on a ruined antiquity. Slowly, the drone began folding its wings, which were also used as solar power generators. Instantly, it transformed into a girl and a cat, unconsciously fell on the ruin.
