Makima

On the surface, Makima seems to be a kind, gentle, social and friendly woman who is usually seen wearing a smile on her face the entire time and acts relaxed and confident even during a crisis, speaking in a professional tone to her workers. As her natural appearance is nearly identical to that of a human, she avoids disclosing her Devil nature to most of her underlings and spends much of the series posing as a human contracted to a Devil rather than a Devil herself. However, this is only a facade that she uses to fulfill her ultimate goal. After the death of Aki Hayakawa, Makima begins to reveal her true colors to Denji. Makima's true face is of someone that is Machiavellian and calculating, who sees people around her as nothing more than "dogs" she can use as much as she likes and must obey her without any hesitation.

Makima has demonstrated herself to be extremely cunning, cold and manipulative as she controls Denji through the promises of a romantic and sexual relationship while also threatening him with outright extermination if he disobeys her. Ruthless and normally dispassionate, she will do whatever it takes to reach her goals, even at the cost of the people she should be protecting.

Makima also realizes that she is not a good person and deems herself as "necessary evil"; a weapon under control of the Japanese government, just like Gun Devil which is under the control of the American government. She is not afraid of her plans derailing, since whether her plans fail or succeed, she will almost always achieve something she wants.

Makima is an extreme fan of Chainsaw Man, the "Hero of Hell". Fascinated by its ability to wipe out the embodied concept of a Devil through consuming them, her stated goal is to bring Chainsaw Man under her control in order to use its abilities to create an ideal world without fear, death, and “bad” movies. However, failure is also acceptable, as it would mean being eaten—an honor according to her.

Makima's true goal, however, was to be together forever with Pochita and lead a happy life with him. She always yearned for something like a family, being incapable of forming equal and meaningful relationships as the Control Devil.
