Ayano Aishi (Yandere-chan)
This teenage girl is the main character in Yandere Simulator. She is controlled by the player, which means her persona, reputation, and actions all depend on what the player does. Her default appearance is that she has fair skin, black hair pulled into a ponytail at the back with bangs swept to the side, and greyish eyes. She is said to be 5' 5" and weigh 90 lbs. She tends to be emotionless in the intro, and is known to be more physically powerful than her schoolmates. Her default clothing is a schoolgirl's sailor uniform. She is voiced by Michaela Laws, currently.
Osana Najimi
This teenage girl's name is based off the Japanese term *osananajimi*, which basically means something along the lines of "childhood friend" and such. Yandere Dev chose this clever name because in Story Mode, she is to be the friend of Senpai for ten years, which basically goes back into their childhood years. Her appearance would be fair skin, orange eyes, long bright-orange hair tied into long twintails with a pink white-polkadotted bow in the middle, and pink white-polka dot leg socks (along with the chosen uniform). She is not programmed in the game yet, but she is set to play the first rival of Ayano. She is only placed in current builds so Yandere-vision can be tested. In Yandere-vision, she will be outlined in red, as so will other rivals. Her persona would be "Social Butterfly." Her club is unknown.
Info-chan
Information about this teen girl is not really known, ironically, but she is an important character whatsoever. Her hobbies include getting information from students, or from anything. Her ambition is to be a journalist. In the duration of the game, she helps out Ayano by providing help with eliminating her rivals. She would only help if the player provides her with panty-shots, in which Info-chan would sell to boys (and some girls) who are willing to pay such money. Her appearance is known, although, and it consists of her having short red hair, brown eyes, and red glasses. She usually wears a smug smile on her face, and her persona would be labeled "Evil." Her club is unknown.
Saki Miyu
This teenage girl is not a rival, but rather an accomplice to a rival due to being best friends with one of the rivals, Kokona Haruka, who is likely to confide personal matters with this girl. Saki is a rather peppy girl who doesn't have much problems, in contrast to her friend. The player can choose to befriend Saki by completing a task for her. That task would be retrieving her bra somewhere on schoolgrounds. Saki, as of now, has long cyan hair into long one-curl twintails, fair skin, and eyes a darker shade of cyan than her hair. Her bust size is the second biggest, at 1.7. Her persona is "Social Butterfly", but it was previously "Loner." She is in the Cooking Club currently. Saki is voiced by Chelsea Druce, currently.
Kokona Haruka
The teenage girl is a current test rival in the game, and is referred to as "everyone's favorite punching bag", as you could eliminate her in so many ways. She can be seen on 7:30 AM on Monday taking a call involving compensated dating, which can be used against her. The player can choose to post this information on the internet. Later, at 12:08 PM, Kokona will tell her best friend, Saki Miyu, about domestic abuse problems. The player can also use this information against her, such as luring her to the rooftop, and throwing her off the rooftop, making it look like a suicide, and leaving a suicide note as well. She can be electrocuted, bullied, drowned, framed for murder, expelled, and doused in blood or water, in terms of eliminating rivals. It is not known whether she will be a rival in the final game or not, but she might be the third rival, which is supposed to be the Cooking Club leader with purple fancy hair. Kokona has purple drillcurls, purple eyes, fair skin, and tied by three people for the largest bustsize in the game, at 2.
Midori Gurin
This teenage girl originally came from Yandere Dev's videos, in which she would represent people with annoying questions for Yandere Dev. She would interrupt Yandere Dev's speech at intervals. This brought comedy to his videos and Yandere Simulator fans loved her. In fact, she was loved so much that she was implemented in the game later on. Yandere Dev hates Midori, and placed her on the rooftop from the beginning of the day so she can be used as a "secondary punching bag." She has green hair with short bangs swept over her forehead, green eyes, and has the persona of "Social Butterfly." In her Student Info profile, provided by Info-chan, it is said that she irritates her teachers and classmates with annoying and irrelevant questions, as she does in Yandere Dev's videos. She is voiced by who is known as MOM0KI. (I work with her on projects.)
Oka Ruto
This teenage girl is usually sad and secluded.

Mai Waifu
The teenage girl's name is based off the words "my" and "waifu." A waifu is known as a female crush in a game. Yandere Dev used joke that he was a Japanese schoolgirl with pink-hair and pink eyes. He customized Mai to this too, except that she now has "rainbow" eyes, meaning that her eyes change color every time she blinks. In her Student Info profile, provided by Info-chan, she is said to have devoted herself to an independent game developer overseas, referencing to Yandere Dev himself (I think what he's trying to tell us is that he loves himself). She has long pink hair, pink eyes, and has tied for the biggest bust-size in the game with Kokona Karuka and the School Nurse, at 2. Her persona is the "Loner" persona. Her club would be gaming.

Senpai (Taro Yamada)
This teenage boy is an upperclassman to Ayano, and is the love interest of her as well. Senpai is classified as a loner, and his only friend is Osana Najimi, a rival of Ayano due to this. Senpai's appearance can be changed to the player's appeal, but his default appearance would be him having fair skin, a bowl cut of black hair, and wearing a black school uniform. His persona is "Loner." He is voiced by who is known by Cruciothe3rd. He is set to not be in any clubs. (Senpai can also be customized to be a girl.)
