Power is a fiend, a dead body possessed by a devil.

She is a Public Safety Devil Hunter who works (against her will) under Makima as a member of an experimental squad in Tokyo Special Division 4. She works alongside her partner Denji, and under supervision by Aki Hayakawa.

Power is childish, greedy, and almost entirely self-motivated. She tends to fights if she has something to gain and is certain of her victory and has no problems in running away from a fight where she is outmatched. She also feels the need to boast her superiority over her fellow Devil Hunters due to her status as a fiend. She has no loyalty to humanity, openly admitting that she will join the winning side. Power is often rude, unkempt, and feels as though those around her should clean up after her. She self-admittedly rarely bathes or flushes the toilet and sees humans as being sensitive for caring about their hygiene so much. As the Blood Fiend, she has the power to freely manipulate the blood within her own body.
