Ayano Aishi, also known as Yandere-Chan or Yan-Chan, is the villainous main protagonist of Yandere Simulator. She was created by YandereDev. She is deeply in love with Taro Yamada. Ayano Aishi has pale skin, dark grey eyes, and straight, mid-back length black hair. She stands at a height of 165 cm 5 ft. 5 in, weighs 43.5 kg 96 lbs,and has average-sized breasts. Her hair is tied into a high ponytail with sharp bangs swept to the right, the middle one being the most prominent, and two strands of hair that frame her face, reaching to her shoulders. She's usually portrayed wearing the default school uniform: a white and navy blue sailor uniform shirt with a red mini scarf, a matching navy blue skirt, black thigh high socks, and black shoes. With all uniforms, she wears black thigh high socks. When in Buraza Town, Ayano will wear a teal-green shirt, blue denim skirt, black thigh high socks, black gloves, and sneakers. Ayano suffers from a fictional type of insanity. This condition doesn't allow her to experience normal, strong feelings. She had been this way since as far back as she could remember,before meeting Taro Yamada for the first time. Ayano doesn't have the ability to feel emotions, empathy, or remorse. She doesn't feel guilt or shame for harming others. However, she can feel pity at times. She knows what the general people consider to be "wrong", but she just doesn't care. Ayano's behavior does not perfectly match the definition of either a sociopath or psychopath, but she is capable of actions that only a psychopath would consider taking--being usually bold and egotistical. She doesn't see the point of fighting students non-lethally besides the delinquents because they will just report her to the teachers. She is also capable of nonviolent elimination methods in order to cause less trouble for Senpai or to run less of a risk of getting caught while doing something violent.
