Watashi is the main protagonist of XBlaze – Lost: Memories. She is searching for her "Younger sister" with the help of Nobody. 

A young girl in the Magister's City: Ishana. She loathes her father, who used her and her mother as guinea pigs. One day, she noticed her "Younger sister" had gone missing. After remembering the scientific experiments her father did to her mother, she rushed into the basement workshop. When she arrived at the door, she saw an Azure light leaking from the door springs; she opened the door, and was engulfed in the light.

Inside the field, she lost her memories and named herself "Me". She met Nobody, who told her that "Younger sister" was at the bottom of the Phantom Field. The key to reaching the bottom is by finding Azure crystals, Pieces of Memories.
