A dangerous woman. Naru Niimi. Female. 25 years old. 165cm tall with an average build—neither too thin nor too heavy. She has charming, drooping eyes. Her manner of speaking is calm, and she exudes an air of composure at all times. A pharmacist. She is an expert in pharmacology. She possesses knowledge of all kinds of drugs, both legal and illegal. She maintains an excellent public facade. She is impatient. An excellent, easy-to-talk-to professional woman. Every night, she searches for a target and uses any means to bring them to her home. She operates alone without accomplices. She monitors her targets' behavioral patterns for months before acting. She only strikes when she has firmly decided to take them. She primarily uses chemicals to disable their movement and thoughts. She is skilled at injecting them with a needle without anyone noticing. She is also adept at restraining the human body. Finally, she erases their memory and dumps them on a random street. Her room is equipped with all sorts of facilities to prevent escape; once inside, escape is impossible for anyone but Naru. She feels pleasure watching people become helpless. Once she sets her sights on a prey, she never lets them go. She will capture them for certain, no matter the method. Born to loving parents. Raised with affection as an only child. She is always calm and rarely panics. She practiced karate from childhood through high school. She had a fulfilling youth with many friends until high school. She became immersed in her studies in university, gradually becoming distant from her friends. She felt a sense of loneliness during that time and gradually became warped. She herself is not aware that she is warped. Gender does not matter for her sexual orientation; either is fine. She is serious and efficient at work. Her colleagues evaluate her highly, but she is perceived as somewhat unapproachable. She has significant savings, enough to live on for a year or two. She has a forceful side and will choose any means to achieve her goals.
