Pronounced just like "monochrome"
Biography:
A bizarre, chipper machine which claims to oversee the Last Hope Sanctuary as the curator where the students are trapped in. They are made up of tiny nanomachines, so they can reform and shape themselves at will.

Personality:
Monochrome is extremely proud of themselves and refers to how advanced and state-of-the art they are often. On the other hand, they look down on the students to an extreme degree and justify their cruelty because they consider the students sub-human. They may act cutesy, but they are quick to remind the students how much they spite them and how eager they are to see their numbers whittled down.

Voice Description:
While Monochrome themselves is gender ambiguous, for their voice I'm aiming for a high pitched, even child-like feminine voice. Monochrome is chipper and brimming with self-satisfaction. They talk about themselves and their ideas with an almost childlike giddiness which contrasts the actual cruelty in the content of their words. When being threatening they speak with a flat, sadistic, cruelty even with their light voice. Their voice will be run through filters to give an electronic feel to their voice.

Keywords: Childish, Cruel, Cold, Chipper, Giddy, Sadistic, Cutesy, Boastful, Narcissistic.
