Eri was an infant abandoned at a church entrance. Her name comes from the piece of paper clasped in her tiny hands.
Once she figured out the ways of the world, she decided to leave the sanctuary of the church and taste the forbidden fruit of the real world. Little is known about her youth that point. Her invigorating, tom-boy personality and keen fighting sense helped her become leader of a gang of street kids. She was recruited for military service when her abilities caught the attention of the Intelligence Agency. As a top agent, who received a special education for the gifted in espionage, Eri made her name known in countless missions.

But Eri, sickened by the succession of assassinations and conspiracies that consumed her conscience, applied for transfer to the special forces squad, Sparrows. Such a request which would normally not have received a second thought was specially approved in light of her record and indispensable abilities.
Eri subsequently assumed the post of demolitions expert in Sparrows. She took the nickname, "Memphis Bombshell," and demonstrated her advanced abilities by putting a premature end to Morden's second coup.
