2B (YoRHa No. 2, Type B)
A blade…with a quiet volition.
An all-purpose battle android deployed as a member of the automated infantry squad, YoRHa. She is equipped with a sword for close-quarters combat, and can attack from range using the “Pod” tactical support system. Members of YoRHa forgo names and are referred to only by their codes. Though regulations forbid them from expressing emotions, each model has its own distinguishing personality, and 2B is comparatively cool, calm, and collected.




9S (YoRHa No. 9, Type S)
A soul…and an ephemeral kindness.
Though he has the ability to attack, this YoRHa android specializes in research missions and excels in collecting information, mainly by hacking. Within YoRHa, 9S is comparatively varied in his emotional expressions and has a kind personality.




A2 (YoRHa Type A, No. 2)
A vortex…of the past and hatred.
The Type A is a YoRHa prototype model that is no longer in use. She specializes in close-range attacks. She was operated on a trial basis in the process of developing official models such as 2B and 9S. Personality-wise, she has little to say and always acts independently.




Pod 042 and Pod 153
These support units are part of every YoRHa soldier’s standard equipment. They come installed with various weapons used for long-range combat, and can also aid their owners in traversal. They can display messages coming in from Command, and they are also capable of exchanging information among themselves to devise strategies. 2B is followed by Pod 042, while 9S is accompanied by Pod 153.




Commander
The leader of the “Bunker,” a military base orbiting Earth. She is in charge of all YoRHa units. Her position demands her to be calm and collected at all times, but she seems to worry for the personal safety of 2B and 9S. She also appears to have some kind of history with YoRHa prototype model A2.




Operator 6O and Operator 21O
Two communications operators permanently stationed at the Bunker.
They are mainly in charge of analyzing intel, and relaying orders to the YoRHa units on the planet’s surface. They have fairly different personalities, with 6O, who’s in charge of 2B, being relatively bright and cheerful, whereas 21O, in charge of 9S, is always cool and composed.




Adam
A mysterious young man.
He wears glasses and is extremely intelligent. He has a generally calm personality, but does not shy away from excessive force in order to attain his goals.

Eve
Adam’s younger twin.
Contrary to Adam, Eve is short-tempered and doesn’t like thinking too much. His brother means the world to him.




Pascal
Despite being a machine lifeform, Pascal is a pacifist and despises any kind of conflict. He is searching for the path to peace, along with other likeminded machine lifeforms. He is very intelligent, and shows a great interest in the history of humanity and machines alike.




Devola and Popola
A pair of old android models residing at the Resistance camp.
They are aware that two identical models went haywire in the distant past, and they’ve always considered themselves responsible somehow. They are unique androids in that they are capable of consuming alcohol.
