A2

YoRHa Type A (Attacker) No.2 or A2 serves as the protagonist of Branch C in NieR:Automata, as well as the final boss in Branch D. She is also a major character in the YoRHa Stage Play.

She is a prototype of the YoRHa android line, and combat data from her and her comrades was used to create the superior current lines, including 2B and 9S. She doesn't like to speak and often keeps to herself.

Three years prior to the events of NieR:Automata, she was a member of the first YoRHa squadron deployed to Earth as part of the Pearl Harbor Descent during the early years of the 14th Machine War. Her alias at the time was No2 which is parsed in Automata as "Number Two". She was portrayed by Ruka Endo in the stage play.
