Malkuth is one of the Sephirot that works for the Facility in the upper layer, Asiyah, and is the head of the Control Team. Her hair is cut short and is colored brown and yellow, with a red hairband. She has brown eyes with no pupils and a dark shadow that covers half of each eye. She wears a regular business suit with a red tie and an armband with her initial on it, "M". She constantly carries a pen and clipboard that is described as "almost worn out."

Malkuth is cheerful, enthusiastic and somewhat impatient, with a clumsy demeanor. She maintains her positive personality even when discussing concerning topics with X and the other Sephiroth. During work, she always tries to bring out the best of herself, giving her all so as to not disappoint Angela or the Manager, as well explaining the rules in understandable but emphatic terms. Malkuth might also consider herself slow and forgetful, the reason for always having a 'to-do' list with her.

Malkuth has a very bubbly and energetic personality, but she is a bit of a klutz at times too. She always works her hardest to do her job well, but is not above destroying those she deems to be too weak to be in her control team. I imagine her voice as higher pitched, with an American accent. However, I am open to any interpretation of the character
