Create an image of an elderly samurai, around 120 years old, who has just awakened from a long coma. He is wandering through a modern Japanese city, looking confused yet dignified. The samurai is dressed in traditional, worn-out armor, with a katana at his side, but his surroundings are a stark contrast--full of neon lights, modern skyscrapers, and bustling city life. His expression should convey a sense of bewilderment and curiosity as he tries to make sense of the unfamiliar world around him.
