Naoko Satomi

Jirou is at university to study engineering. On traveling back to Tokyo from a holiday, he meets a young girl named Naoko, who is traveling with her maid. At this time, the Great Kanto Earthquake of 1923 hits, which stops the train and causes Naoko's maid to break her leg. Jirou delivers Naoko and her maid to Naoko's family, then walks away without giving his name.
