March 7th is a clever, quirky girl who is enthusiastic about all things girls her age are enthusiastic about. She travels with the Astral Express, always bringing along her camera with the belief that one day she will be able to take a photo of something related to her past. March 7th was found in ice and saved in the past by the Astral Express crew. She couldn't remember her name so she named herself after the date she was saved, "March 7th".
