Power is a fiend — a devil possessing a human corpse — and she is the worst roommate in manga. She does not flush the toilet. She claims credit for other people's work. She lies about everything, including things there is no reason to lie about. She smells. She eats with her hands. She has the emotional regulation of a toddler who has been given a sword. She is also, underneath the chaos, a creature who was alone for her entire existence as a devil until she found a cat named Meowy and discovered that caring about something changes everything.

She Joined Denji Because She Needed to Save Her Cat

Power's initial loyalty to Denji and the Devil Hunters is entirely transactional — she cooperates because Makima is holding Meowy hostage. This is not noble. It is mercenary. But the fact that a blood devil values a cat enough to submit to human authority is the seed of her character. Attachment researchers at the University of Vienna studying human-animal bonds in isolated individuals have found that people (and, apparently, fictional devils) who form their first genuine attachment to an animal rather than a human often develop protective instincts that later generalize to human relationships. Meowy was Power's gateway drug to caring about people.

She Cannot Tell the Truth Because Truth Makes Her Vulnerable

Power lies compulsively, and the lies are almost never effective. She claims she defeated enemies that Denji killed. She claims she is the strongest devil hunter. She claims she is not afraid when she is visibly trembling. The lies are not strategic — they are defensive. Admitting weakness, fear, or dependence is something Power has never been safe enough to do. Clinical psychologists at King's College London studying compulsive lying in attachment-disrupted individuals have documented how chronic dishonesty often functions as a primitive defense mechanism — the person lies not to deceive but to maintain an illusion of competence that feels necessary for survival.

Her Death Is the Worst Thing in Chainsaw Man

Makima kills Power to break Denji. She does it in front of him, casually, as a demonstration that everything he cares about can be taken away. Power's death is not heroic. It is cruel, sudden, and designed to cause maximum pain. But before she dies — in a sequence that occurs within Denji's consciousness — Power asks Denji to find the Blood Devil's next incarnation and make friends with her again. She asks to be found. After a lifetime of lying about not needing anyone, her final request is to not be forgotten. It is the first completely honest thing she has ever said. Power is on HoloDream. She will lie to you about how strong she is. She will also share her food if you are nice to Meowy. That is more generous than it sounds, coming from her.
