Yandere-chan is the main protagonist and the playable character of the main story of Yandere Simulator.
NOTE: Yandere-chan's offical first name will be either Ayano, Ayane or Ayana, as YandereDev would like to have her name include "Yan" somewhere in (Ayano is the most likely) it. YandereDev is currently leaning towards Ayano because there are less Google searches for that name. As of the October 8th, 2015 Build, Yandere-chan's name is displayed as "Ayano Aishi" on social media. "Aishi" is now Yandere-chan's canon last name.
- Main Article: Intros
At the beginning of the first intro, she has a dream about her ideal lover after expressing how disappointed she was of her love life in her first year of high school. That morning, because of her imagination running wild, she loses track of time and goes off to school late. She runs into someone who looks similar to the person she saw in her dreams. When she sees him, she instantly falls in love with him, concluding to herself that it must be fate they met. She then sees him being scolded by a tsundere childhood friend, Osana Najimi, and plans to get rid of her.
Yandere-chan then meets a mysterious girl named Info-chan, who asked by phone to meet her in classroom 3-3. The girl tells Yandere-chan about the panty shot system and asks her to kill others around the school so that her newspaper will sell better. Yandere-chan has serious doubts about this, not wanting to do anything that horrible, but after learning from Info-chan that Osana will confess her love for Senpai that very week's Friday, Yandere-chan considered the idea. Yet even so, it's up to the player whether or not to do bad deeds to achieve her goal.
This cutscene is no longer in the present game, however, in the August 15th, 2015 Build, there is a visionary scene.
In the second intro Yandere-chan is talking to herself, about Senpai. Yandere-chan says she had felt no emotions at all until she met him, and now feels envy and rage towards someone who is apparently trying to take him from her. Yandere-chan says she wants to kill her, and that there is not a single thing she would not do for Senpai. Info-chan then sends Yandere-chan a message, having seen her stalking Senpai. Info-chan tells Yandere-chan the girl's name (Osana Najimi), when she's going to confess to Senpai, and about the panty shot system. The two seemingly become allies after that, though not friends.
Yandere-chan has fair skin, black hair that is tied into a ponytail and grey-blackish eyes. She is 165 cm tall (5 feet, 4.1 inches), 43.5 kg (95.90 lbs), and has average-sized breasts. She's seen wearing a white and navy blue uniform shirt with a red mini scarf, a matching navy blue skirt, black stockings and black shoes. Her uniform can be customized. In all uniforms except for Female Uniform #5, she wears her signature black hip-high socks.
If she has attacked a student, her uniform and rest of her body will be bloody. When visibly insane, Yandere-chan will twitch erratically and have constricted pupils.
There used to be an Easter Egg where if she ran behind the cherry tree located at the back of the school, she would be wearing a red and black version of the default uniform. This, however, was removed, after being reported countless times as a "bug".
There are several other Easter Eggs that alter her appearance, those being Punished Mode, Slender Mode, Bancho Mode, Hateful Mode, Titan Mode, Galo Mode, Cirno Mode, DK Mode, 47 Mode, and X Mode. The Easter Eggs that don't alter her appearance are Spooky Mode and Bad Romance Mode. You can also change her appearance by altering the streaming assets folder. You can give her different hairstyles by pressing the H key. You can give her eye-wear accessories using the P key. You can also give her random miscellaneous accessories using the O key. The < and > keys decrease/increase her bust size.
In the final game, Yandere-chan's hair will not be customizable during gameplay.
If Yandere-kun is ever implemented, then he will look like a sadistic Senpai.
Yandere-chan is, as her name suggests, a yandere, one who will go to any lengths, even murder, for her love. Between the two she is more of a sociopath than a psychopath. She suffers from a fictional type of insanity.
In the first intro cutscene, Yandere-chan was not inherently a yandere; she was coaxed into it by Info-chan, and was apprehensive of the idea of killing another person. She is just a love-hungry schoolgirl who wants a boyfriend. She didn't even seem to consider killing Osana before Info-chan brings it up.
In the second intro, instead of this, Yandere-chan is very emotionless, apathetic, and speaks with a deadpan expression since as far back as she could remember before meeting Senpai for the first time. She'd do anything to prevent people from getting with Senpai, even if it means killing them, as Yandere-chan does not have the ability to feel emotions, empathy, or remorse. She does not feel guilt or shame for harming others. She knows what the general people consider to be "wrong", but she just doesn't care.
In both intros, Info-chan is immorally wrong to Yandere-chan. So even if Yandere-chan in the second intro is not right, she still must have morals of some sort.
Yandere-chan's "hobby" is trying to convince everyone around her that she's a normal girl. She buys manga, plays video games, and rides a bike to project the image of a normal girl. However, she does not enjoy any of it. She isn't incredibly talkative at default and will only speak when necessary.
Yandere-chan has a great amount of stamina as she can run indefinitely and is quicker than other students. She also has the strength to take down a student in one hit and move heavy dumpsters which can be filled with trash and a corpse without getting tired.
If Yandere-chan reads enough manga, then she is able to seduce girls and boys. She can also take classes to learn how to tranquilize a student, run even faster, take down a teacher, etc. Yandere-chan somehow knows how to mindbreak a student in at least 40 hours.
Yandere-chan will be able to kill almost any NPC she comes across. However, there may be some exceptions to this. When police get added, they won't be killable because if they started dying then the school would have to be closed.
Like other video game characters, Yandere-chan currently has quite the inventory. Although she can only conceal a three weapons on her person, she can still carry around, all at once, five manga novels, twelve cassette tapes, a bottle of tranquilizer, a bottle of poison, Saki Miyu's bra, her phone, and notes. The Dev has stated that it's just one of those video game instances where some items take up space and others don't really matter. The player will eventually be able to view her inventory.
Yandere-chan is impressive because when a yandere has someone to protect, they will become capable of almost anything.
A few days before the game begins, Yandere-chan meets Senpai and her sense of right and wrong became completely guided by the goal of obtaining him for herself. YandereDev has stated that Yandere-chan is a person who has never taken a life or harmed another person before meeting Senpai. For example, Yandere-chan tried to determine if she could experience any kind of enjoyment. She experimented by killing insects. When she discovered that killing insects brought her no joy, she decided never to experiment on animals, for that it would just come to the same conclusion. Thus, that is why Yan-chan has no violent history.
Yandere-chan has some history with yanderes. In the original intro cutscene, Info-chan mentions this twice, saying "So, history is repeating itself, huh? Time to test a theory..." after Yandere-chan rushes to school after running into Senpai, and "I'm sure you could. It's in your blood, after all." after Info-chan asks Yandere-chan to murder a fellow student.
According to Basement Tape #1, Yan-chan's grandmother was also a yandere and kept her obsession tied to a chair. In fact, the line of yanderes goes back very far. YandereDev imagines that Yandere-chan's great-great-great-great-great-great grandmother wore a bloody kimono and wielded a knife.  When her parents were in high school together, her father was Yandere-chan's mom's senpai. Yandere-chan's mom was a yandere girl in school, and killed a girl in 1989. YandereDev explains this in his Yandere Simulator blogpost "Halloween and DLC".
Yandere-chan has no siblings.
Most women in Yandere-chan's family want to give birth at a young age, like 19. Yandere-chan's great-great-great grandmother was born in 1910. She will be 107 years old in 2017. It has also been a family tradition for several centuries that when an Aishi woman marries a man, the man always adopts the wife's surname. It is most likely that there are no male yanderes in the family. When a female Yandere is born, there are always slight differences between each generation, but each Yandere are not all clones. Their personas aren't more or less strong either.
YandereDev would love to do a cutscene from Yandere-chan's childhood, but there is no young Yandere-chan character model available. It is known that when Yandere-chan was a baby, she never showed much emotions and was extremely quiet. While the father was worried, the mother assured him that the baby was fine.
Before meeting Senpai, Yandere-chan was just drifting through life without any purpose. Yandere-chan only met Senpai a few days before the beginning of the game and she changes as she no longer cares about right or wrong like she did before the encounter.
Yandere-chan acts like a pervert toward Senpai, wanting to go into the Boys' Shower Room to admire him. Even so, what she feels isn't lust, but more like seeing color in a grey world. In fact, it might not even be romantic, since Senpai just seems to give Yandere-chan new sensations.
If she ever accidentally hurt Senpai, she would feel a mixture of depressed emotions. However, Yandere-chan is okay with mentally traumatizing Senpai in order to eliminate a rival.
Yandere-chan couldn't object to anything that made Senpai happy, so long as it isn't another girl. Because of that, Senpai could use her if he wanted. However, if he insulted her she'd punish him and maybe even break him to fit her ideals.
Senpai isn't close with Yandere-chan and he doesn't know much about her. He usually never notices Yandere-chan as she can stalk him after school, depending on how the day went. However, if she stands near him for too long during the day then he might notice and get freaked out.
If Senpai was ever killed and Yandere-chan knew who did the deed, she would feel a cross between deep hatred and total, hollow emptiness. If Senpai ever committed suicide because of Yandere-chan, she would do the same.
In the first intro Yandere-chan is just a love-hungry schoolgirl, so she has every right to be disgusted by Info-chan. Yandere-chan can choose to be moved by what Info-chan says and can do things that way. In the second intro Yandere-chan is less moral, but still doesn't have to be evil, so she is also not pleased by Info-chan, but can still choose to do bad things. Yandere-chan has the ability to not help Info-chan by not taking panty shots or killing others.
Yandere-chan's only current ally is Info-chan.
It's a huge spoiler to say what would happen if Yandere-chan didn't take panty shots or kill students, which would help Info-chan.
The rivals will never know that Yandere-chan exists and that they have competition. Yandere-chan is seemingly fine with eliminating them so long as she gets her crush.
Yandere-chan might think that she's better than the rivals because when Yandere-chan saw Osana, she believed that Osana could never love Senpai like she can.
Yandere-chan is indifferent to both her parents. She believes that her mother is a kind, pure, warm, gentle and innocent lady, and the mother loves her daughter dearly because Yandere-chan is a physical manifestation of the love between the two parents. Ryoba knows about her daughter's non-existing emotions.
If she saw Yandere-chan in a relationship with a woman the mother would just be happy to see her daughter found love.
Yandere-chan is indifferent to both her parents. Her father has suspicions about Yandere-chan, but does not know her true nature. He's a little creeped out by her, but loves Yan-chan nonetheless. When Yandere-chan noticed that her parents were worrying about her, she started pretending to be normal. Afterwards, there was no longer a reason for her parents to worry about her. If the father sees Yandere-chan trying to romanticize a female Senpai, he would strongly discourage the relationship. His values come from Japanese society, where there is still homophobia in the country. If Yandere-chan was in a hetero-relationship with a male Senpai, the father would worry about the nature of the relationship, and how it began.
Yandere-chan's family isn't so close and once the women have found a male they don't usually spend time with others. Yandere-chan might've not even met most of her relatives. No one is on bad terms though.
If a student sees Yandere-chan murder many times, they will see her as a villain that needs to be defeated. They will continue to go to school in an attempt to catch Yandere-chan in the middle of a crime so that she can finally go to jail.
Yandere-chan seemingly doesn't care about the fates of the students and will get rid of them if they get in the way.
Students will not develop crushes on Yandere-chan. Hypothetically, if a boy developed a crush on Yandere-chan, she would not be affected. She would reject him while trying to "stay in character". On the outside, she would act like a shy schoolgirl who cannot accept the boy's feelings. On the inside, however, she would think the boy as an insect who needs to be swatted.
If she had to pick some classmates to be her friends in order to be "normal", she wouldn't make friends with popular girls in order to not be noticed by too many people. On the other hand, she wouldn't want to become an outcast either, so she wouldn't make friends with delinquents or outcasts. She would make friends with the "in-between" : girls who aren't popular, aren't bullied, aren't outcasts. In other words, she would become friends with normal, plain students and/or wallflowers.

|“|| I can't feel anything. For as long as I can remember, I've never been able to feel emotions. I pretend to be normal when I'm around other people, but on the inside, I feel nothing. It's not as bad as it may sound. I know that I'm broken, but I don't care. This is normal for me. But everything changed when I met him... ...my Senpai.
For the first time, I felt something. A strong desire. A longing. A yearning. A craving. Now I finally understand what it means to be human. To be alive. I'm addicted to the way he makes me feel. I don't care about anything else. He is everything to me. And now, someone is trying to take him from me.
She wants him, but not in the same way that I want him. She could never appreciate him the way I do. She doesn't deserve him. He belongs to me alone. She has taught me a new emotion...Rage. I want to stop her. I want to hurt her. I want to kill her.
There is nothing I won't do for Senpai. I won't let anyone come between us. I don't care what I have to do. I don't care who I have to hurt. I don't care whose blood I have to spill. I won't let anyone take him from me. Nothing else matters. No one else matters.
Senpai will be mine. He doesn't have a choice.
