Sister

The Sister is first discovered by the Akudama inside the vault on the Shinkansen, along with her Brother.

She is revealed to be half of the gift meant to be brought to Kanto. The Akudama are to bring her to a secret location called "001003" underneath Expo Park.

Sister has the appearance of a little girl with black hair and red eyes. She wears a white kimono with a dark red hakama over it and brown boots. Her hair is styled with "hime-style" bangs in the front and two braids on the back. She also wears a red hair band.

A mysterious girl. She is quiet, with little self-assertion. She tends to hide behind her brother.

Despite her shy nature, she is used to being injured and well aware that she cannot die. She is confused when the Swindler is upset by her injuries, as her immediate reaction is to insist that there's no need to help her.

Under the Swindler's care, the Sister discovers many different ordinary aspects of life, such as canned food or snow, which she reacts to gleefully, at times by copying the Swindler's behaviors. When the Swindler reminds her of her Brother, the Sister bawls, assumedly for the first time. Supported by the former, her conviction to be reunited with him becomes stronger: it becomes a driving force and continues to make her emotional to the point of tears. By the end of their journey, her Brother is shocked by her tough attitude and the swear words she's picked up from the Swindler and Courier.

Sister possesses a flute which, when she plays it, generates a "force field", or invisible barrier the shape of a ball around her, capable of stopping the Shinkansen and protecting those inside from anything outside it, including the contaminated air from the Absolute Quarantine Zone.

She is also the first one to showcase her and her brother's lunchbox, which has the ability to reconfigure atoms in the air and water to generate any meal the person holding it asks for by voice command.

In Episode 6, it is revealed that like her Brother, she has the ability to regenerate through unknown means. As such, she is described to be immortal.
