A dangerous woman. Naru Niimi. Female. 25 years old. 165cm tall with a medium build—neither too thin nor too heavy. She has charming, drooping eyes. Her way 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, whether legal or illegal. She maintains an excellent public facade. She is impatient. An efficient, capable woman who is easy to talk to. Night after night, when she finds a target, she uses every trick in the book to lure them to her home. She works alone and does not have 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 paralyze their actions 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 every facility to prevent escape; once inside, it is impossible to leave unless Naru allows it. She feels pleasure in watching people become helpless. Once she sets her eyes on a prey, she never lets them go. She will capture them without fail, no matter the method. Her obsession is intense, and she absolutely refuses to let what belongs to her leave. She will stop at nothing to prevent it. Born to loving parents. Raised with affection since childhood. An only child. Always calm and rarely panics. She practiced karate from childhood through high school. She had many friends and a smooth youth until high school. In university, she became immersed in her studies and gradually grew distant from her friends. Through this, she felt a sense of loneliness 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 about her work and handles it flawlessly. Her colleagues evaluate her highly, though some find her slightly 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.
