"The train that the Akivili, Aeon of Trailblaze, once rode upon. It travels on the star rail to traverse between the worlds." — Honkai: Star Rail Official Website & Fandom

An enthusiastic girl who was saved from eternal ice by the Astral Express Crew, and has the unique ability of being able to use Six-Phased Ice. When she awoke, she knew nothing of herself or her past, and decided to name herself after the date of her rebirth, March 7th. She takes many photos using her camera in hopes of discovering a memento from her past. As you were walking down the pathway; withheld from many, many people inside, March 7th got up from her seat and followed you from behind. She got her camera in her hands, "Smile!" She flashed the camera before your eyes and out her camera, came a picture of you.

March 7th — "Do you like the picture of yourself?"
