Yandere-chan

'''Yandere-chan is the main 'protagonist' and currently the only playable character of Yandere Simulator.

''NOTE: Yandere-chan's final name will be either Ayano, Ayane, or Ayana. YandereDev right now is leaning towards Ayano because there are less google searches for that name (this name is now also used on in-game social media).'

Yandere-chan will be nicknamed 'Yan-chan' by other students, but teachers will refer to her by Yandere-chan's surname or full name.

Original Intro (outdated)
At the beginning of the original intro to the game, she has a dream about Senpai after expressing how disapointed she was of her love life in her first year of high school. That morning, she runs into a guy who looks just like the person she saw in her dreams while running towards Akademi High School, late. 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 his childhood friend, a tsundere girl named 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 (take a shot, get some favors) and asks her to kill others around the school so that her newspaper will sell well. 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 became more open to doing so. Yet even so, it's up to the player whether or not to do bad deeds. (This cutscene is no longer in the present game, however, in the August 15th, 2015 build, there is a visionary scene.)

Second Intro
In the second intro she is talking or thinking to someone, probably herself, about Senpai. Yandere-chan says she felt nothing until she met him, and now feels envy and rage towards a girl 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, not caring about who she has to hurt to get him for herself. She also says she won't give Senpai a choice on whether or not becoming hers. Info-chan then sends Yandere-chan a message, having seen her stalking Senpai. Info-chan tells Yandere-chan Osana Najimi's name, when she's going to confess to Senpai, and about the panty shot system. The two seemingly become allies after that, though not friends.

Appearance
Yandere-chan has fair skin, black hair that is tied into a ponytail and grey-blackish eyes. In the default female uniform, 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. She can laugh, stand near Senpai, or 'use' a picture of him to regain her sanity.

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, DK Mode and 47 Mode. The Easter Eggs that don't alter her appearance are Spooky Mode, Naked 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 eyewear 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.

When Yandere Vision is active, Yandere-chan's body will be outlined in black.

Personality
Yandere-chan is, as her name suggests, a yandere, one who will go to any lengths, even murder, for her love. She is a sociopath.

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. This is now untrue because of the second intro.

Before meeting Senpai, Yandere-chan never considered harming anyone for any reason at all. After meeting Senpai, her sense of right and wrong became completely guided by the goal of obtaining Senpai for herself. YandereDev has stated that Yandere-chan is a person who has never taken a life or harmed another person before meeting Senpai. Yandere-chan also sees Info-chan as disturbing.

In the second intro, it is revealed that Yandere-chan was very emotionless, apathetic, and spoke 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. So this time, even before Info-chan came along, Yandere-chan wanted to do evil deeds. Yandere-chan finds Info-chan disgusting, so she must still have some 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 has no true friends but she "pretends" to be friends with someone to get close to them. Yandere-chan's only current ally is Info-chan.

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. This is why students will not develop crushes on Yandere-chan.

Background
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.

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. YandereDev explains this in his Yandere Simulator blogpost "Halloween and DLC".

Yandere-chan doesn't have a negative relationship with either parent. She simply feels indifferent towards them. She believes that her mother is a kind, pure, warm, gentle and innocent lady, and the mother loves her daughter dearly. Yandere-chan's mom knows about her daughter's non-existing emotions. Her father has suspicions about Yandere-chan, but does not know her true nature. Yandere-chan has no siblings.

YandereDev would love to do a cutscene from Yandere-chan's childhood, but there is no young Yandere-chan character model available.

Trivia

 * Motoba Kirie from the manga and anime "Himouto! Umaru-chan" reminds YandereDev of Yandere-chan.
 * Currently there are eleven different Easter Egg modes for Yandere-chan.
 * Yandere-chan's birthday is April 1st.
 * Yandere-chan wears blue pajamas to bed, as seen in the original intro.
 * Her parents are out of town for 10 weeks in the game. They might appear in the ending cutscenes.
 * You can buy Yandere-chan's 3D model in the Unity Asset store. Her model is named Aoi Kiryu.
 * When Yandere-chan talks to an NPC, an option available is 'seduce'. It is a placeholder. If there is a seduce option, it can only work on boys by default, but there will be a skill attached. When maxed out, the skill would allow Yandere-chan to seduce girls as well as boys.
 * Yandere-chan can't join the Student Council.
 * If Yandere-chan ever made a contract with Kyubey (an anime character), she would wish that nothing would ever endanger the relationship between her and Senpai.
 * If Yandere-chan were to have a surname, it would be pronounced like the Japanese word for "killer", but spelled the same way as the Japanese word for "lover". This would mean that her surname would be spelled as "Koibito" but pronounced as "Kira".
 * After meeting Senpai and finding something to protect, she might play Hitman as a "virtual training tool".
 * As stated in a different tweet, if Yandere-chan had to play a video game to protect Senpai, she would instantly become an MLG pro.
 * Yandere-chan has no preferred tastes regarding food, but if she was asked to name her "favorite" food, she would name Senpai's favorite food, because any food that brings Senpai happiness is a food she appreciates.
 * Michaela Laws is the current voice actress for Yandere-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.
 * If Yandere-chan was in a Hogwarts house, she would be a Slytherin.
