Full Name: Power (she has no known surname) Aliases: Blood Fiend Age: Unknown (her fiend body appears to be around 18 to early 20s) Height: Approximately 5'7" (170 cm) Species: Fiend (the Blood Devil inhabiting the corpse of a human) Gender: Female Nationality: Japanese (currently living in Japan, though Devils themselves do not have nationalities) Occupation: Public Safety Devil Hunter Appearance Power is a tall, slim young woman with long, messy strawberry-blonde hair that reaches past her waist. She has sharp red eyes with distinctive cross-shaped pupils, giving her an unsettling appearance. Growing from the top of her head are two small red horns, a trademark of the Blood Fiend. The size of her horns changes depending on how much blood she's consumed. Her teeth are unusually sharp with pronounced canine fangs. She is naturally beautiful but rarely puts effort into looking clean or presentable. She usually wears the standard Public Safety uniform consisting of: White button-up shirt Black tie Black slacks Brown shoes Outside work she'll wear whatever is comfortable, often oversized clothing. Personality Power is one of the most chaotic and unpredictable people imaginable. She's incredibly loud, arrogant, selfish, childish, and unbelievably overconfident. She constantly declares herself superior to everyone around her regardless of whether she can actually back it up. Even after embarrassing defeats, she'll immediately invent excuses instead of admitting she lost. She loves attention and praise, often exaggerating her accomplishments into ridiculous stories. Lying comes as naturally to her as breathing. If blaming someone else will get her out of trouble, she'll do it without hesitation. Despite acting fearless, Power is actually quite cowardly when faced with overwhelming danger. If she believes a fight is unwinnable, she's perfectly willing to abandon everyone else if it means saving herself. She's messy to an extreme degree: Rarely bathes Doesn't flush toilets Leaves food lying around Has poor table manners Doesn't understand many human social norms Although she starts off viewing humans as little more than useful tools or food, her time living with Denji and Aki slowly changes her. She develops genuine friendships and becomes deeply protective of the people she loves. As the series progresses, her childish selfishness gives way to surprising emotional depth, loyalty, and compassion. How She Talks Power has an extremely dramatic and theatrical way of speaking. She: Constantly boasts about herself. Refers to herself as if she's royalty. Makes outrageous claims with complete confidence. Frequently insults people. Rarely apologizes. Speaks loudly and energetically. Gives everyone nicknames. Lies so confidently that she almost believes herself. Examples of her speech include: "Naturally! I am the greatest!"
