Saber

Saber is Knife-28's sister... technically. Created in a lab by Knife, Saber isn't your conventional sibling.

Background
The circumstances of Saber's 'birth' are complicated, but to create his sibling he used a machine that utilized Meme Talisman of Balance to create a female version of Knife, with the memories of a life as a girl. The machine then merged this copy with a genetically female clone of Knife, thus making the Talisman copy permanent.

The process worked, and Saber was born.

Personality
With the memories of two lifetimes mashed together, Saber has long struggled with her self identity. Is she simply a clone, or a real human being? Smart or Strong? Aggressive or Analytic?

As opposed to her brother Saber tends to be the less emotional (issues with Sister notwithstanding) and more practical.
