    Akademi Faculty 
These are the women (and one man) whose mission it is to ensure the wellbeing of Akademi High School and its students.

Reina Nana
"Your conduct is unacceptable! Disciplinary measures will be taken!"

Voiced by: Rachael Messer

The teacher(s) of Akademi High School. Crossing her guarantees a Non-Standard Game Over unless you've prepared enough in your Physical Education class.

Tropes that apply to all teachers

  • Action Girl: Strong, fast, tough. Do NOT anger a Sensei-chan.
  • Adults Are Useless: Zigzagged. If a murder scene is cleaned up before she and a student show up, she'll assume it was a prank and walk off. She doesn't bother asking the student more about it. She just pretends nothing happened. Due to there being no reaction to blood in the debug builds, she won't even notice a very obvious trail of blood leading to a body around the corner. But if you don't clean up before she gets there, she will call the police and guard the corpse, making it impossible to move it. If you break school rules, she will send you to the Guidance Counselor. And if she sees you doing psychotic things, she will give chase. That being said, they are pretty much completely useless in regards to bullying. Not only do they not stop Musume and her friends from tormenting the other students, but in earlier builds, the Bullies could bully the teachers themselves and they wouldn't retaliate!
  • All There in the Manual: The teachers do have names – Rino Fuka (Ayano's teacher), Shiori Risa, Reina Nana, Natsuki Anna, Kaho Kanon (Senpai's teacher), and Karin Hana.
  • Badass Teacher: If Ayano tries to attack her or if she knows that Yan-chan killed someone, she'll disarm and pin her to the ground within a matter of seconds. According to Word of God, after the 1989 incident, all teachers at Akademi were required to have extensive self-defense training.
  • Brainy Brunette: They were this in old builds.
    • Averted for their replacements, whose hairstyles and hair colors are randomly generated.
  • Curb-Stomp Battle: Will give one to you if you don't train hard enough to take it.
  • Curtains Match the Window: Brown hair, brown eyes. In old builds only.
  • Did You Just Punch Out Cthulhu?: Downplayed. The teachers are in no way godlike, but they are pretty tough. It's only possible to take teachers down if you have leveled up your Physical stats enough, barring Easter Eggs and mods.
  • The Dreaded: For almost every Let's Player out there. Then again, because of this, some people like to taunt her because she can't easily go to some places.
  • Everyone Has Standards: If Yan-chan hangs around in a class that's not hers, the teacher will yell at her for disrupting her class and send her to the Guidance Counselor. Also, she won't take too kindly to attempted murder, successful murder, bloody clothes, or panty shots. As of current builds, she does not react to nudity (no one does) if you manage to glitch out of the locker room while nude or use the nude easter egg, but it's safe to say that eventually she won't like that either.
  • Failed a Spot Check: No one in the Debug builds notices blood, which can lead to a very bizarre situation in which a Teacher's Pet witnesses murder and goes to get a teacher, you drag the body around a corner, the teacher arrives, fails to notice the extremely obvious blood trail leading towards the body, and scolds the Teacher's Pet for lying.
  • Hidden Badass: Do NOT get Sensei-chan mad.
  • Lightning Bruiser: She is fast enough to outrun a base-level Yan-chan, and strong enough to easily physically overpower her.
  • Mama Bear: The teachers genuinely care about the students' safety. If you murder someone, they'll come charging at you full-force.
  • Meganekko: Many of them wear glasses.
  • Nice Shoes: Little high heels with ribbons on them.
  • Oh, Crap!: When witnessing something bad happen.
  • Prim and Proper Bun: Two of them (Reina Nana and Rino Fuka) have one.
  • Reasonable Authority Figure: When she discovers a corpse, the first thing she does is call the cops. If she sees Ayano with blood, a weapon, or just acting suspicious in any way, she will send Yan-chan to the Guidance Counselor, or, if her behavior is obviously murderous, pin her down and have her arrested.
  • Stern Teacher: Appears to be the default. She won't hesitate to call Yan-chan out on arriving to class late or intruding on the incorrect class, and will send you to the Guidance Counselor if she catches you doing something weird. That said, she seems very protective of her students.
  • Suspiciously Similar Substitute: Her model is identical to Ayano's, except taller and with brown hair instead of black. Later updates gave the teachers different hairstyles to make them less obvious carbon copies.
  • This Cannot Be!: Whenever she sees a dead body, she'll say this.
    Sensei: "No, it can't be…!"
  • Tranquil Fury: Normally, when she's giving chase or when you break school rules, she will shout like crazy. However, if she catches you during a chase or if you try to kill her, she slips into this before pinning you to the ground.
    Sensei: "Just what do you think you're doing?"
  • Two First Names: Like everyone who doesn't have a Punny Name.
  • Wide Eyes and Shrunken Irises: When scared… though given that you're no match for hernote , perhaps "horrified" would be a better term.

Reina Nana

One of the teachers. She has shoulder length red hair, and glasses. Teacher of class 1-1.

Rino Fuka

One of the teachers. She has short green hair, and glasses. She is Ayano’s teacher, teacher of class 2-1.

Shiori Risa

One of the teachers. She has shoulder length blue hair, and glasses. Teacher of class 2-2.

Karin Hana

One of the teachers. She has straight teal hair, and glasses. Teacher of class 3-1.

Natsuki Anna

One of the teachers. She has yellow hair, and oval-framed glasses. Teacher of class 1-2.

Kaho Kanon

One of the teachers. She has purple hair in a bun, and glasses. She is Senpai’s teacher, teacher of class 3-2.

Kyoshi Taiso

Formerly a celebrity Olympic athelete before being hired as Akademi High's gym teacher. While she does take her job seriously, she gets a little awkward around one student. She first appeared in the "Interim Build". Her function in the game is to make it difficult for Ayano to easily dispatch her rivals – during the morning and afternoon she stands guard by the front gate, and during class time she patrols the Faculty Room where the test answer sheet is. She has all the powers of a normal teacher.

  • The Ace: When it comes to swimming, at least - she has won 23 gold medals as an Olympic athlete. Also, just like all the other teachers, she will put you down if you attack anyone.
  • All There in the Manual: Her personality profile says that she was a former Olympic athlete, hired because of Akademi's tendency to get celebrity teachers.
  • Badass Teacher: Same as all the others. Attack her, she'll put you down.
  • But Not Too Foreign: With her blonde hair, blue eyes, and friendly extroverted demeanor, she fits the Japanese stereotype of an American or European. However, her name is not the least bit Western.
  • Celebrity Survivor: As mentioned, she's a famous Olympic athlete, and since she's generally in relatively out of the way areas, she has a good chance of surviving should Yan-chan go on a rampage.
  • Character Tics: She has a habit of swaying her hips from side to side when standing still.
  • Curtains Match the Window: The only faculty member who averts this.
  • Dark-Skinned Blonde: She has blonde hair, and a tanner skin tone than most NPCs thus far. Justified by her preference for being outdoors.
  • Nice Girl: She is described as friendly and humble, despite being a famous olympic athlete.
  • Outdoorsy Gal: She'd rather be outside getting some exercise than inside doing paperwork.
  • Passionate Sports Girl: When she's indoors, she'll frequently perform stretching exercises.
  • The Pirates Who Don't Do Anything: She's officially Akademi's gym teacher, but her routine does not ever take her anywhere near the gym, nor is she shown to teach. During class time, she instead patrols the faculty room to make it hard for Yan-chan to steal test materials to frame and expel a rival.
  • Punny Name: Kyoshitaiso (体操教師) translates to "gymnastics teacher".
  • Reasonable Authority Figure: With a personality of "Friendly, but Strict", how can she not be?

Nasu Kankoshi, the Nurse

Akademi High's regular nurse, present for nine of the game's ten weeks. Her function is to keep the player from easily nabbing useful items – tranquilizer, syringe, emetic, etc. – from her office. You can steal her keys to get at those items, but you'll get sent to Genka if she catches you at it. Like the normal teachers and Kyoshi, she is killable, but her slot will be filled the next day by a randomly generated replacement. She will be absent for the sixth week, with her position being filled by Muja Kina, but she'll return after Muja's rival week.

  • Combat Medic: She's just as tough to deal with as the regular teachers and Kyoshi if you trigger her.
  • Curtains Match the Window: Brown hair and eyes, albeit noticeably lighter than the classroom teachers' formerly.
  • Failed a Spot Check: If you successfully complete the QTE to steal her keys, she (currently) won't notice anything is amiss no matter how much stuff you steal. Averted if you fail; she'll slap you with a Genka's office visit for touching her butt.
  • Hidden Badass: She doesn't look like much and never leaves the infirmary… unless she sees you with a corpse, at which point she will give chase and bust you just like any other teacher.
  • Punny Name: Nasu (ナース) is the usual way to say "nurse" in modern Japanese. Kankoshi is a traditional word for nurse. So her name is "Nurse Nurse" or, more officially, Nurse Nurse Nurse.
  • Repetitive Name: Nasu (ナース) is the usual way to say "nurse" in modern Japanese. Kankoshi is a traditional word for nurse. So her name is "Nurse Nurse"
  • School Nurse: If her name, outfit, and the fact she never leaves the infirmary weren't proof enough.
  • Written-In Absence: She will be gone during the sixth week of the game to make way for Muja, Ayano's rival for that week, and will return the week after. Why she will be absent is not yet known, but will be discussed in the final game.

Genka Kunahito, the Counselor
"Don't misbehave."

Voiced by: Marissa Lenti

The Guidance Counselor of Akademi High School, whose role is to administrate proper punishment for misbehaving students.

  • Adult Fear: She becomes visibly depressed if Yandere-chan blames the delinquents for her being covered in blood, as this makes her realize that allowing the delinquents to carry weapons on school grounds could've gotten innocent (or in this case, seemingly innocent) students hurt or even killed.
  • All or Nothing: She has ten weeks to reform the delinquents or she will be dismissed from Akademi.
  • Absolute Cleavage: Her open shirt does not hide a whole lot.
  • Adults Are Useless: She failed to step in when five students were harassed to the point of near-suicide because of a lack of concrete evidence, eventually causing them to become the Delinquents. She deeply regrets this failure.
  • The Atoner: When five boys were being harassed and bullied, she did not help them, resulting in them becoming delinquents to protect themselves. She blames herself entirely for this, and is willing to risk her career and position to help them reform—she has made a deal with the headmaster that if she cannot reform them in ten weeks, she will leave the school.
  • Beauty Mark: A small one on the far side of her right cheek.
  • Everyone Has Standards: She legitimately wants to help as much as possible. That said, push her enough and she can expel you.
  • Expy: Is said to have been inspired by Meiko Shiraki and Headmistress Fiora.
  • Hot Teacher: Variant on the theme, in that she's a school guidance counselor, not a teacher. Still, she was deliberately designed to have sex appeal. Her shirt has a plunging neckline which reveals her ample cleavage.
  • It's All My Fault: She blames herself for the delinquents becoming what they are.
  • Jerk with a Heart of Gold: She's extremely harsh and strict, but she genuinely cares, and she wants to take good care of the students. She failed to help the delinquents in the past, but sincerely regrets it, and takes full responsibility for what happened. She's also willing to risk her career to help them.
  • Ms. Fanservice: Her shapely figure and flattering outfit definitely qualify her for this.
  • Must Make Amends: She is determined to reform the delinquents in order to make up for not helping them when they were being bullied, to the point that she is willing to risk her position at Akademi for them.
  • My God, What Have I Done?: It's downplayed, but it's made very clear she feels this way about how she handled the delinquents in the past. She fully owns up to the fact that her inaction when they were being bullied is what pushed them into becoming what they are, and she deeply regrets this.
  • My Greatest Failure: The Delinquent Backstory video reveals that she feels this way because of her former policy of requiring concrete evidence of bullying for getting involved made it that the delinquents, before they became such, were easily bullied until Osoro came into the picture.
  • Not So Stoic: In the "Delinquent Backstory" video, she gets noticeably emotional when talking about her failure to help the delinquents, to the point of sounding like she is tearing or choking up.
  • Prim and Proper Bun: Fitting, considering her role in the game.
  • Punny Name: Her name is a pun on Genkaku na Hito (厳格な人), which means "disciplinarian".
  • Reality Ensues:
    • In the "Delinquent Backstory" video, her inaction in preventing the delinquents from being bullied transformed them into bullies. She considers this to be her greatest failure, to the point that she offered to resign if she didn't reform them and have Osoro suspended.
    • Genka is a Reasonable Authority Figure who legitimately wants to help. That said, she has a limit to her patience. If you're proven to be a problem student, she'll get increasingly more angry with you. If you use the same excuse multiple times, she'll call you out on it. If she thinks you aren't taking it seriously, she will get frustrated. She can give you a Game Over where she expels or suspends you, and will make it very clear she wants you out of her office immediately.
  • Reasonable Authority Figure: Her personality is "Slightly Strict", which is described as someone who "genuinely wants to help". Of course, she has her limits where she will stop forgiving any troublemakers.
  • Scary Shiny Glasses: Her profile picture has one of her glasses become opaque. However, in the game they are clear.
  • Schmuck Bait: Using the "flirt" or "threaten" options after being sent to her office. As hilarious as the former may sound, and as tempting as the latter may seem, neither will get you out of trouble. The latter actually gives you an instant game over.
  • Sexy Spectacles: Wears a pair of small, oval shaped glasses.
  • Stern Teacher: Subverted. Despite being a faculty member with the Strict personality type, and a disciplinarian at that, YandereDev has said that she is a Reasonable Authority Figure who genuinely wants to be helpful to the students, but her patience has a limit.
  • The Unfought: She is unkillable – you may interact with her, but she has no hitbox. Genka is one of only two NPCs you directly encounter at school who will never be able to be killed; Headmaster Kocho is the other. note 
  • Unwitting Pawn: Can be manipulated by Yan-chan into expelling her romantic rivals or removing the delinquents as a threat.

Kocho Shuyona
In 2020
In 1989 
"It… it's you!"

Akademi High School's Headmaster since its founding in 1985. He was originally a cheerful, optimistic man full of hope, but as the years went by, he became a cynical, world-weary old man. Knows enough to be afraid of Ayano, and is very triggerhappy with his taser when she gets near.

  • Accomplice by Inaction: He knows what Ayano really is and that she's after one of his students. He removed his own child from the school while Ayano is "active", but otherwise he's chosen to do nothing.
  • Adorkable: Young!Kocho was this, as seen in his first tape. He's just so giddy at getting to be the headmaster of one of the most promising schools in the country. He has since lost this trait.
  • Ambiguously Evil: The Journalist mentions that he pays the police and media to stay away from Akademi even when there's a crime on campus. However, he's also been described as someone who was once idealistic, but the years have made him cynical and jaded. In addition, his Wham Line after tasering Ayano hints at a connection between him and Megami Saikou's family, and she's also Ambiguously Evil. He could, at least, be an Anti-Villain.
    • Part of the connection has been explained- Saikou Corp is funding the school because Saisho Saikou wanted his daughter to be educated in the very best environment. What this means for the present, however, has yet to be explained.
  • Break the Cutie: He was once full of hope, but the years have been cruel to him.
  • Curb-Stomp Battle: A "fight" between him and Ayano will end with her ass on the floor of his office.
  • The Cynic: He became one before the events of the game, losing faith in the world and its youth.
  • Dark Secret: The final headmaster tape implies that Kocho himself has something to hide as Info-chan used that to blackmail him to let her into the school and be uninterrupted in her work.
  • The Dreaded: Seriously. Do NOT get on this guy's bad side. He is armed and will attack. Actually, the player is already screwed on this front, as he'll freak out the instant he sees you due to Ayano being a textbook example of Generation Xerox.
  • Formerly Fit: He used to be in decent shape, but these days he's noticeably pudgy.
  • Get Out!: If Ayano enters his office, he tells her in no uncertain terms to leave.
  • The Ghost: Was originally planned to be this before YanDev changed his mind and decided to make him physically present during regular gameplay – he first appeared on October 1st, 2017.
  • Hopeless Boss Fight: If Ayano comes at him with malicious intent, she will eat taser.
  • Laser-Guided Karma: He considers Info-chan blackmailing him with screenshots of certain folders on his computer to be this for unspecified actions he committed in the past.
  • Meaningful Name: Kōchō (校長) means "Headmaster".
  • Obstructive Bureaucrat: Under his administration, the school somehow convinced the police to only investigate crimes committed on school grounds for 6 hours maximum. This is very convenient for a Yandere looking to not get caught.
  • Punny Name: His name, Kōchō (校長) means "Headmaster".
  • Properly Paranoid: He will taze Ayano merely for coming too close to him. But then, she is Ayano, and more importantly, he knows she's just like her mother.
  • Schmuck Bait: The Dev alluded to this months before Kocho's introduction by encouraging players to, once he appeared in the game, try and kill him and see what happens. On that same note — try appearing before Kocho while covered in blood, dragging/carrying a body, holding a weapon (especially his own katana you just stole from him), or do none of those things but stay in his presence for more than one minute. Surely nothing bad will happen to you!
  • Shock and Awe: First shown in YandereDev's Let's Examine Persona series of videos, where he is seen in concept art wielding an X-26 Taser. Sure enough, when he was introduced into the game several months later, he has that taser on him and will use it on Ayano without hesitation.
  • Stopped Caring: By the time Ayano meets him, he is a year away from retirement and no longer gives a shit about anything, dumping his workload on the guidance counselor.
  • The Unfought: He is one of the only NPCs you'll meet who can never be killed (Info-chan and Genka are the others) due to his importance to the game's story. Unlike those two, however, he will interact with Ayano without prompting. Note, however, that doing so is guaranteed to end very very badly for the player.
  • Weirdness Censor: He is the only character in the debug builds (at this time) who has a unique reaction to Yan-chan doing something silly, such as crawling around while wearing a box. Unfortunately for her, he has zero sense of humor.
  • Wham Line: The build that introduced him also introduced a new type of Game Over – if you get too close to him, stay in his presence too long, or do anything even remotely yandere within his line of sight, you will be tazed into unconsciousness. That's not the wham; it's what happens next – instead of any of the standard texts ("Heartbroken", "Expelled", etc.), the red letters read simply "??????????" and we hear Kocho say into his phone, "Mister Saikou... The deal is off." What exactly he means by this is currently a mystery.
  • Wide-Eyed Idealist: When he first got the job, he was a fit, energetic man who was full of hope. However, by the time the game starts, he's become pessimistic and world-weary.
  • Would Hurt a Child: He will not hesitate to taze Ayano if she triggers him, and it is very easy to do so.


    Other Akademi 

Phantom Girl
The first tragedy. A beautiful flower plucked far too soon. She cannot yet rest.

This is a ghostly apparition who can sometimes be seen when you try to take a picture with your phone. She figures very heavily in the game's backstory.

  • Boy Meets Ghoul: It's been pitched that she may become a rival in a DLC if the game does well.
  • Camping a Crapper: She was killed by Ryoba Aishi in the girl's bathroom, and now haunts it. However, it is unclear whether the Phantom Girl was simply led there or if Ryoba waited for the Phantom Girl to go there on her own and then killed her.
  • Creepy Child: Is a teenager, and wherever you take a photo she'll always be looking at you.
  • Curtains Match The Windows: A picture for 1980s mode has been released which shows a girl that looks a lot like her, only more… lively. Said picture reveals that she had reddish gold eyes in life to go with her auburn hair.
  • Easter Egg: A rather creepy one.
  • Expy: She's a reference to the Hanako-san Urban Legend (which is the equivalent of the Western "Bloody Mary").
  • Fan Disservice: Because her clothes are ripped up, it's actually fairly easy to see her panties. Thing is, she's a monstrous-looking ghost girl.
  • Ghostly Goals: If the planned DLC mission pack happens, she will get a physical form and will romance Senpai in revenge for what Ayano's mother did in the past. Dev suggests that the Occult Club will be able to help you out with the ghost problem, because you won't be able to kill the Phantom Girl normally.
  • Hero Antagonist:
    • Her being one of these is what led to her death.
    • If the game sells well enough to justify it, YandereDev would like to add a DLC bonus mission where she becomes Yan-chan's rival for Senpai's affections.
  • Hitodama Light: Has two blue flames floating nearby her, indicating her status as a ghost.
  • Jacob Marley Apparel: She wears a school uniform. It is noticeably tattered.
  • Losing a Shoe in the Struggle: Implied. If you look at her picture again, you'll notice she's missing a shoe.
  • Murder the Hypotenuse: Ryoba definitely killed her. The Journalist reveals in one of his secret tapes that he learned the poor girl had a crush on the boy who would become Mr Aishi.
  • Our Ghosts Are Different: She can only be seen through cameras. Her appearance is heavily inspired by Japanese ghost stories – note the two Hitodama Light followers and hitaikakushi. She also has yellow eyes, pale skin, and a shadowed face.
  • Revenge: Word of God says that a future DLC may focus on her attempt. How would she do it? By manifesting a physical form and trying to steal Senpai personally.
  • Spooky Photographs: Originally, she could be found by the lone cherry tree behind the school. That was just for testing purposes though. You can find her by taking a photograph in the girl's bathroom on the third floor.
  • Supernatural Gold Eyes: Has one (her left) that glows brightly.

The Placeholder Delinquents
Does this look like a club to you? Beat it.
"Huh?! You got a death wish?!"

The Placeholder Delinquents were a gang of 10 students (five boys and five girls) who hung around school's incinerator for several real-life years. They served as an obstacle to Yandere-chan, who had to plan around their presence at the incinerator when she's disposing of evidence lest they chase her and knock her out. The "Unconscious" game over they dished out could not be avoided- the delinquents had infinite acceleration and could run through all barriers. The Placeholder Delinquents were replaced in April 2018 by a gang of five boys, whose character profiles are in the Male Students section. The placeholder designs will appear in 1980s mode.

  • A Lighter Shade of Black: Sure, they're delinquents, but they're nowhere near as bad as Ayano, Info-chan, the bullies, or (possibly) Yui Rio and Haruto Yuto. They do not commit, aid in, or approve of murder (and will in fact mess you up if they see that you are guilty of it), they look out for each other and will befriend you in the final game if your reputation is low enough, they are mostly willing to keep to themselves if you don't mess with them, and YandereDev has stated that even their leader (one of your rivals) isn't actually evil.
  • Bad is Good and Good is Bad: One of the planned features is to make it so that if Yan-chan has a high reputation, they'll be even more disdainful towards her, but if she has a low reputation, they'll treat her as one of their own.
  • Batter Up!: One of the Delinquents wields a baseball bat.
  • Big Brother Worship: One of the male Delinquents is the Yakuza's younger brother, who will set you up with his services if you do him a big enough favor. He's described as adoring and looking up to his big brother. However, the Yakuza actually wants him to stay on the right path, as he doesn't want him to be a criminal either.
  • Blood Knight: They'll jeer at and threaten Yan-chan if she intrudes on them, and if she approaches them with a weapon drawn, they'll get ready for a fight.
  • Crowbar Combatant: One of them wields a crowbar.
  • Delinquent Hair: They all have bleached blonde spikey hair.
  • Did You Just Punch Out Cthulhu?: Not even Yan-chan possessed by a freaking demon could take them in a fight before April 2018.
  • Even Evil Has Standards: Ne'er-do-wells though they may be, if they see you with a corpse (or part of one), they will attempt to waste you on the spot.
  • Fish out of Temporal Water: Aesthetically. Their design clashed with the modern atmosphere of the rest of the academy, and thus they were moved to 1980s mode once the new Delinquents were established.
  • Honor Among Thieves: If your reputation's low enough to be accepted by them, they'll look out for you.
  • Implacable Man: Trying to fight one of them will not end well.
    • To put it in perspective, until April 2018, they were literally invincible. Not even the Easter Eggs that One-Hit Kill everyone else with an AI (Senpai included) had any effect on them.
    • The movement of most NPCs in the game (students and teachers) is restricted to a field reaching only as far out as the pool. The incomplete delinquents, on the other hand, can and will chase you anywhere. Yes, anywhere. Even if you try glitching out of the map or teleporting to the Void, they will still hunt you down. They also have infinite acceleration (meaning Falcon Mode becomes useless after about fifteen seconds), so if you provoke them, you're basically screwed.† 
    • As of April 2018, this got toned down. They don't charge you and bash you into oblivion so much if they see you commit murder, but they'll attack you all the same, forcing you into the combat minigame. Even if you win, you have to draw your weapon and put them down for good, otherwise they won't stop coming after you until you are well and truly KO'd.
  • Japanese Delinquents: Ya reckon?!
    • As YanDev noted, the boys in particular resembled 80's-era delinquents (as seen in, say, AKIRA or Great Teacher Onizuka) rather than modern ones – current-era delinquents typically have bleached hair, like Osoro. As of April 2018, they were given more era-appropriate hairdos, and the placeholder delinquents will instead appear in the proposed 1980s mode.
  • Jerkass: None of them are terribly nice. If you approach them, they'll mock you, and even crack a joke about breaking your cello if you have the case. They'll also rudely brush you off if you try and speak to them. Then again, what else do you expect from delinquents?
  • One-Hit KO: Prior to April 2018, provoking one of them will have them clock you in the skull with their weapon, leaving Yan-chan comatose and leading to a Game Over (where the rival likely got to confess to Senpai unimpeded). This got averted in the April 2018 update, where they'll only knock you out if they see that you're a murderer.
  • Pipe Pain: One of them carries around a lead pipe as a weapon.
  • The Pirates Who Don't Do Anything: Despite being delinquents, they are not shown causing trouble on campus. They seam perfectly willing to keep to themselves, and while they do insult and threaten Ayano if she goes into their territory, they won't actually attack her unless she pulls a weapon on them, tries to attack them, kills someone in front of them, or is seen holding a corpse or body part. In the video about the Bullies, YandereDev confirms that they keep to themselves and don't cause trouble unless they feel threatened, which arguably makes the Bullies bigger delinquents than the Delinquents themselves.
  • Put on a Bus: YandereDev jokingly said the video introducing the proper Delinquents that he sent them back in time to 1989 since they look more in that time period anyway.

Mr. Jazzy Feet
The Light Music Club's pet turtle.


Two boys that spent all of their free time in the library. They exist to demonstrate things Kokona likes for use in the Matchmaking elimination. They were removed on January 1st, 2019.

  • Curtains Match the Window: Study-kun A averts this by being one of the few characters to have different colored hair and eyes.
  • Nerds Are Sexy: Kokona is hot for them because she finds intelligence very sexy.

"This girl is talking to Senpai. That's unacceptable."

A former test rival, used to demonstrate how to get away with murder. Later builds have removed her from the game as elimination methods got more complex than 'stab and incinerate body', and Kokona Haruka has taken her place as the test rival. She was coded with a Loner (then called Coward) persona, as that was the only persona for girls at that time.

  • Butt-Monkey: Her entire reason for existing was to be killed by Yandere-chan and cleaned up so the police wouldn't find any evidence. Her routine was designed to facilitate that, as she would talk to Senpai (making her a rival in need of elimination) and then go stand near the incinerator and politely wait there all day.
  • Curtains Match the Window: Both her hair and eyes are yellow.
  • Dummied Out: She's never appeared in a public build. The closest the public got to playing with her is in a video starring her that YandereDev made about getting away with murder.
  • Flat Character: She's a loner, knows Senpai, and hangs out around the Incinerator. That's all we know about her, since she tested some very basic features.
  • Girlish Pigtails: Her hair was done up in twin pigtails.
  • No Name Given: Since she was never a real character.
  • Palette Swap: She looks like Koharu Hinata with yellow hair and eyes instead of green. It's been downplayed as the game's been updated, though, since Koharu's hairstyle has been made more unique.


Stay away from me!
A former student used to demonstrate the reaction of students with the Loner persona (then the only girl persona) to murder. She hung out by the incinerator all day, putting her in the perfect location to see Yandere-chan murder Victim-chan.


The original NPC students, used in the game's very earliest builds. They use the original, unaltered 'Aoi Kiryu' model, and as such are basically Yan-chan with blue hair and eyes instead of black. Soon after the original school building was implemented, they were replaced by the Rainbow Six.

  • Clone Army: They are identical to each other and, with the exception of color, to Yandere-chan. The dev even refers to them as "clones of Yandere-chan" in his video explaining the history of Kokona Haruka (who was added along with her friends to give the school some diversity).
  • Dummied Out: Student-chan had served her purpose by the time more unique characters were implemented, and was removed from the game.
  • Flat Character: They're more of this than even the placeholder club leaders- at least the Club Leaders have lines and their own appearance.
  • Palette Swap: Of Yandere-chan, although it's more accurate that Ayano is a palette swap of them, since the Aoi Kiryu model was recolored for Yan-chan.
  • Too Dumb to Live: In the first dismemberment and sanity meter videos, they would emote a scared reaction to Yandere-chan if she was bloody or visibly insane, but wouldn't do anything beyond that. It's justified since these were very early stages in the game's development- they don't even have the school setting, just the incinerator and a few walls. Doing anything beyond noticing a scary appearance was just not programmed in at that time.

A gynoid being built by Homu Kurusu, who stands on a platform in the Science Club room all day.
  • Exorcist Head: She is capable of turning her head 360 degrees, as shown in the club benefits video.
  • Replacement Goldfish: Rumored to be based on Homu's deceased twin sister.


The Succubus/Lust Demon
Ara ara! You're a cute little thing...
"Do you want to play with me? Or…perhaps you want to become one of us?"

Voiced by: Michaela Laws

One of the five demons encountered by using the Ritual Knife.

  • Bi the Way: She flirts with Ayano, asking her if she wants to "play" with her.
  • Black Eyes of Evil: Her eyes are solid black.
  • Eerie Pale-Skinned Brunette: She has paper-white skin with black markings, black hair, and she is a demoness.
  • Gainaxing: Unlike all the other well-endowed female characters, her breasts noticeably move as she breathes.
  • Greater-Scope Villain: There are implications that she may be the biggest bad in the entire game. On top of there having to be something fundamentally wrong with the Aishi clan (what with the Yandere mindset, one based on obsessive LOVE, going back many generations), Yan-chan's ability to contact demons (despite being the biggest greenhorn in the Occult Club, if she joins) is a bit of a red flag, and the Succubus even looks a bit like Ayano herself (and is even voiced by Yan-chan's voice actress).
  • Humanoid Abomination: Looks the most human out of the five demons, along with the empty demon, but the fact that the other three look either unnatural or twisted shows that she's not as natural as she seems herself.
  • Two Girls to a Team: As of the October 14th 2018 build, she no longer the only female demon around.
  • Was Once a Man: According to the April Fool's Day Dating Sim Burning Love, humans become demons when they commune with one, and offer a blood sacrifice in exchange for a price. It's unclear how canon this tidbit is, but if it's true for Yandere Simulator proper, then this is the case.
  • You Are Not Ready: She tells Yan-chan that it's too soon for her to become a demoness herself, but to be patient.

The Fiend/Flame Demon
"A mortal? Here? How curious…"

Voiced by: Patrick Seymour

One of the five demons encountered by using the Ritual Knife. His ritual was the second to be implemented into the game.

Also appears in a YanSim-related Dating Sim called Burning Love as the romance lead.

  • Ambiguously Bi: In Burning Love, thanks to the player character's Ambiguous Gender.
  • Ambiguously Gay: In Burning Love, thanks to the player character's Ambiguous Gender.
  • Boring Insult: In his original dialogue, he said that he finds Ayano boring and wants nothing to do with her. This was later replaced with a speech saying he finds her unworthy of his power.
  • Bring It: He tells Sakura, "DO YOUR WORST" when challenging them to make him enjoy their date.
  • Do Not Taunt Cthulhu: He has little patience for Sakura's constant flame puns. This could potentially lead to Your Soul Is Mine below.
  • Evil Sounds Deep: He has a very deep voice.
  • Humanoid Abomination: Not as terrifying as The Horror, but still a particularly unnatural entity from the beyond.
  • Kill It with Fire: What his power is. Not even Senpai is immune to fire. note 
  • Interspecies Romance: With the Player Character if you get the Good Ending of Burning Love.
  • Super Empowering: In the January 2017 build, the Fiend's power-up was added to the game. If Ayano heats the Ritual Knife and stabs it into the Skull, he'll give her a taste of his power. If she drags five charred corpses into the ritual circle, he will deem her worthy and give her a charcoal grey gown and the ability to shoot flames from her hands. note 
  • Was Once a Man: In Burning Love, he reveals that this is the case for all demons. A human can become a demon if they commune with one and offer a blood sacrifice to form a pact. In his particular case, he was born into a wealthy family in 1431, and saw his family be beaten and burnt alive by peasants. He struck a deal with a demon, and got his revenge by making the peasants experience every single thing his family did and worse. It's unclear just how canon this backstory is, however.
  • Woobie, Destroyer of Worlds: If Burning Love is to be believed, he was once a normal human who saw his family suffer a Cruel and Unusual Death. After making a Deal with the Devil, he got his revenge and lost his humanity.
  • Wreathed in Flames: Other than his uniform, he is composed of spectral white flames.
  • You Are Not Ready: He tells Yan-chan that she's not worthy of his power, and to come back once she's proved herself. See above for how she can prove herself.
  • You Have Got to Be Kidding Me!: In Burning Love, if the Player Character tells the Flame Demon that they're lost, he will be dumbfounded by the idea that a human got lost and accidentally wandered into another plane of existence.
  • Your Soul Is Mine: He does this to Sakura if their date goes poorly.

The Horror/Pain Demon
Arms removed... Body distorted...
Descendants must feel... what I felt...

One of the five demons encountered by using the Ritual Knife. His ritual was the first to be implemented into the game.

  • Body Horror: His arms look like they've atrophied off (though he heavily implies they were forcibly removed from him) and his mouth is distorted horribly.
  • Demonic Possession: Inflicts this on Yan-chan should the conditions for invoking it be fulfilled.
  • Expy: Its appearance – especially its earthly manifestation – looks a lot like the Dead Hand, although what it actually does is more reminiscent of Diclonius vectors.
  • Ghostly Gape: Its lower jaw is stretched so that its mouth is ghoulishly distorted.
  • Humanoid Abomination: A horrifying creature from the beyond presenting itself in a ghoulish mockery of the human shape.
  • Noble Demon: He's a powerful demon who demands sacrifices, and could easily betray Ayano if he wanted to (since she's merely a human, as opposed to him being a Physical God). That said, he's nice enough to make it so his dark gift doesn't harm Senpai.
  • Pragmatic Villainy: If you manage to give it vengeance, the demon will give Yan-chan ten hands that dismember anyone who comes close… except Senpai. The Horror is kind enough to spare him from your bloody rampage.
  • Roaring Rampage of Revenge: It wants revenge for a past injustice and its arms being cut off. Fulfill that, and it will be happy to lend Yan-chan a hand… or ten.
  • Super Empowering: If Ayano places a certain number of dismembered body parts into the ritual circle, he'll gladly lend her a hand or ten.
  • Was Once a Man: Its speech upon talking to it suggests that it was once a normal human who died a Cruel and Unusual Death. If Burning Love is to be believed, all demons were once humans who made a pact with a demon.

Death Demon
One of the five demons encountered by using the Ritual Knife.

The Spider Husk/Empty Demon

One of the five demons encountered by using the Ritual Knife. Her ritual was the third to be implemented.

  • Assimilation Plot: Once the ritual has been enacted the leaders of each club will look and behave like the placeholder club leaders.
  • Kill and Replace: Her ritual involves sacrificing each of the club leaders so the placeholder club leaders can take their place.
  • Red Eyes, Take Warning: Has eight of them! Like a spider.
  • Spiders Are Scary: Her face has several spider-like features.
  • Two Girls to a Team: After the October 14th, 2018 build, she and the Lust Demon are the only female demons.

Placeholder Club Leaders
"You have joined the club".

Voiced By: Michaela Laws

Due to time constraints, YandereDev included these soulless automatons beginning with the "Clubs" Update to allow players to try out some of the club mechanics without having to complete a bunch of new students. They are Deliberately Monochrome female students with short hair that covers almost all of their face. Yandere-chan can only interact with them as club leaders, and they won't react to anything else.

    Rainbow Girls
From left to right: Yui Rio, Yuna Hina, Koharu Hinata, Mei Mio, Saki Miyu, and Kokona Haruka.

The first NPC studentsnote  to be programmed into the game. All of them first appeared in February 2015 and received their current names two months later. On August 18th, 2018 they were removed, with the exception of Saki and Kokona.

Tropes Unique to the Rainbow Girls

  • Bitch in Sheep's Clothing: The ones who were removed at any rate. While Yan-chan can gossip with nearly every NPC student, this group immediately claims disgust upon hearing that test-rival Kokona engages in Compensated Dating, and they'll exile her to sit on the roof by herself. Even Saki, Kokona's best friend, stops talking to her. These are the same girls Kokona made a snack for earlier in the week. While Mei, Yuna, and Koharu only act this way if they find out about the Compensated Dating, Yui… is a different case.
  • Put on a Bus: Most of them were removed from the game in the August 18, 2018 build because they weren't contributing anything to the game and YandereDev wanted to free up room for more important characters — only Kokona and Saki remained. That said, YandereDev would like to bring them back if he can improve the game's performance.
  • Two First Names: Word of God has confirmed that the "Rainbow Six" are named from a list of the most popular Japanese girl's names in 2012.
  • With Friends Like These...: While this is very likely to happen with the true rivals in the final game, the debug builds contain a good example. The other Rainbow Girls cut ties with Kokona and evidently participate in bullying her once it comes out – thanks to Yan-chan/you – that she's essentially prostituting herself. It is not known whether they simply didn't know about her father's debt problem (in which case, one must wonder why, if they were her friends, did it never occur to them to ask Kokona why she would do this), or they do know and have cut her off anyway. Either way… ouch.
    • In the specific case of Saki, YanDev implied that she gave up trying to protect her best friend to avoid becoming a target of bullying herself.

Mei Mio

"Wow...that's pretty gross...I expected better from Kokona-chan..."

A former Junior-year student at school (Class 2-2). She was a Teacher's Pet and a member of the Cooking Club. Her hair and eyes were cobalt blue.

  • Alliterative Name: Both her first and last name started with an 'm'.
  • Anime Hair: Cobalt blue with ahoge.
    • Prior to her first redesign, she wore her hair in three ponytails.
  • Hidden Depths: Used to be in the Light Music Club. One wonders what instrument she played.
    • Prior to the November 2015 update, she was in the Gardening Club.
    • invokedDruelbozo heavily implied she was a bit of a bookworm by giving her a pair of reading glasses and a stereotypical librarian's hairstyle.
  • Idiot Hair: She had a strand of hair sticking up that's tall enough to be cut off by her profile picture.
  • Innocent Blue Eyes: Seemed pretty innocent.
  • Meganekko: An image posted by Druelbozo (one of the game's now-former modelers) shows her with blue reading glasses. As of the 9/1/2017 update, she wore glasses in-game, too.
  • Prim and Proper Bun: It's difficult to see in her profile pic, but her hair (aside from the ahoge) was pulled back into one of these as of her second hair redesign.
  • Teacher's Pet: She was the only female student with this persona until the science club was added.
  • Tomboyish Ponytail: Her first redesign (which lasted for all of two months) gave her one, though she didn’t actually have a tomboy personality… or any personality besides being a bookworm.
  • You Gotta Have Blue Hair: Mei was the only girl whose hair is literally this. note 

Koharu Hinata

"Seriously? I didn't think there would be anyone like that in our school..."

A second-year student at school, in class 2-1, the same class as Ayano. She's a Social Butterfly and a member of the Cooking Club. Her hair and eyes are green.

  • Badass Bystander: Up until the February 1st 2016 build, she had the Hero persona – the only person outside the Martial Arts Club to have that trait. Keep in mind that, unlike the Martial Arts Club members, she most likely didn't have any training whatsoever, but she'd still attempt to take Yan-chan down anyway.
  • Girlish Pigtails: Color aside, Koharu has probably the most "normal" hairstyle of any girl aside from Yan-chan.
  • Hidden Depths: An unusual case of losing these as development has continued.
    • She was originally in the Photography Club and appeared to be quicker to notice Yan-chan taking panty shots than the other students.
    • From the "School Redesign"note  build to the "Personalities & Photography"note  build, she was coded as a Hero, the only student not in the Martial Arts Club to be one. If she saw Yan-chan murder or drag a body, she'd jump in to stop her personally.
  • Took a Level in Badass: Game Development example. Originally, she was just a Loner like every other girl at the school at the time, but from November 2015 to February 2016 she had the Heroic personality, and would fight Yan-chan if triggered. Inverted in later builds, however, as she became a Social Butterfly.

Yuna Hina

"I wasn't sure if I should say anything about it, but I saw her doing that last week, too..."

A first-year student at school, Class 1-2. She is a Social Butterfly and a member of the Cooking Club. Her hair and eyes are yellow.

Yui Rio

"They had it coming! Don't worry — I won't tell anyone what I saw." note 

A first-year student at school, Class 1-1. She is a member of the Cooking Club and has the "Spiteful" personality trait, meaning that she will approve of murder if the victim is someone she dislikes (otherwise, she'll act like a Loner would). Her hair and eyes are fire-engine red.

  • Ambiguously Gay: In a full body reference photo of the Rainbow Six, she is shown trying to grab Yuna's butt.
  • Bitch in Sheep's Clothing: She was given the Evil persona in February 2016. If she sees you commit murder, she will express her approval. However, she'll stop talking to you because she doesn't want to be considered an accomplice if you get caught. Word of God has also said that she probably doesn't actually like the rest of the Rainbow Six, and only spends time with them as a form of social protection.
    • Downplayed after the 'Evil' persona was re-defined as Spiteful, since she'll only do this with someone who's bullied her or someone who's targeted for bullying.
  • Evil Redhead: Has bright red hair, and she will act impressed if she sees you kill someone she doesn't like.
  • False Friend: She may hang out with the other "Rainbow Girls", and they may think that she is their friend, but she'll still turn on any one who has a low reputation.
  • Fashionable Asymmetry: Wears her ponytail on the right side of her head.
  • Finger-Tenting: She does this when she spots the body of someone she hates, along with the mother of all smirks.
    • In the earliest builds, she was in the Martial Arts Club, which made sense given her boyish physique.
  • Hypocrite: She will hate anyone who bullies her, but she'll also have No Sympathy for a bullied student, even if she had also been bullied by the same people.
  • Hazy Feel Turn: She went from being evil, approving of any murder she saw, and promising to keep your secret safe to being spiteful, only approving of some murders, and actively showing shock when other students are killed; calling the cops and trying to convince others that Ayano is a killer. She is still a kitten-hating jerk and the category of murders she will approve of include any student unpopular enough to be bullied, even if said students were her friends, so while she may not be as cruel and heartless as previously, she's still by no means a good person.
  • Idiot Ball: She now only approves of murders of Bullies that have picked on her and students unpopular enough to be bullied. If you kill anyone else in front of her, she will try and convince the school that Ayano is a killer. However, she fails to make the connection if she sees you kill a Bully and there have already been murders before that killing or people continue to wind up murdered later on.
  • Jerkass: Not (yet) much evidence of this in-game, persona aside. Outside the game, though, Dev's own artists have been building this up as a defining part of Yui's personality.
    • Some of Druelbozo's pictures imply she has a habit of picking on the rest of the Rainbow Six. One full-body reference of the group shows her reaching out to Yuna in what was described as "getting that booty." Another commissioned work shows Yui stealing Mei's glasses.
    • An unused picture from the bucket-based update video shows this; while everyone else reacts with disgust after Yan-chan splashes liquids on Kokona, Yui smiles and gives a thumbs-up.
    • Then there's this fanart (featured on Dev's blog) of Kokona burning to death. While most of the girls are backing away in horror, Yui smirks as she snaps a photo with her cellphone.
  • Kindhearted Cat Lover: Inverted. She's Spiteful and hates cats.
  • No Sympathy: For anyone bullying her or for someone else who's been targeted for bullying, if you kill them.
  • Pet the Dog:
    • She will boost your reputation if you compliment her or give her an octodog. Seems she isn't the completely ungrateful type at least.
    • She will show shock if anyone she does not dislike gets murdered, and will call the cops and try to convince others that Ayano is a killer.
  • Psycho Lesbian: Aside from the fact that she, like the other girls, can become attracted to Yan-chan if Yan-chan maxes out her seduction, there's also the promo art of her trying to grope Yuna's butt. Downplayed after her persona became Spiteful.
  • Psychotic Smirk: Has one if she sees Yan-chan murder someone she doesn't like and the first time you encounter her the following day.
  • Red Eyes, Take Warning: Her eyes are red, and she has a Spiteful persona, meaning you can kill some people in front of her and she won't do a thing.
  • Textile Work Is Feminine: In some late-2015-era builds, she was in the Sewing Club (which no longer exists).
  • Token Evil Teammate: She is the only member of the Rainbow Six who's Spiteful.

    Rainbow Boys 
The first six NPC boys (aside from Senpai) to be added into the game, back in Spring 2015. Like the Rainbow Girls, they all have Two First Names. On August 18th, 2018 they were all removed except Riku.

Sora Sosuke

"Don't talk to me! I know you killed someone. I'll make sure everyone knows what you've done."note 

A boy in his senior year at Akademi, in Class 3-1. Belongs to the Drama Club.note  His hair and eyes are teal.

Ryusei Koki

A student in his Junior year at school, in Class 2-2. Belongs to the Art Club. His hair and eyes are indigo blue.

Hayato Haruki

A student at school. Belongs to the Light Music Club. His hair and eyes are green. He is in class 2-1.

  • Alliterative Name: Both his first name and his last name start with an 'h'.
  • Hidden Depths: Was in the Photography Club.
    • In a few builds, he wore the same headband used by the Martial Arts Club despite not being a member. No one knew why. Perhaps he's a bit of a ditz?

Sota Yuki
"The show is about Miyuki's struggle to cut it as a magical girl even though she's relatively weak, and none of the other magical girls respect her. Trust me, man, this show is freaking amazing."

Voiced by: Nathan Sharp

A freshman student, in Class 1-2. His hair and eyes are yellow.

  • Adorkable: The way he fanboys over "Magical Girl Pretty Miyuki". He even makes an awkward anime pose at one point. Also, from the way he talks about it, he seems to be a troper.
  • The Generic Guy: Even by the Rainbow Boys' standards, he doesn't really stand out — his hair colour isn't that farfetched to a Westerner's eyes, and its style is extremely common. His only real personality trait is that he's a fanboy of Magical Girl shows like Magical Girl Pretty Miyuki.
  • Hidden Depths: Was once in the Light Music Club.
    • He was also once briefly listed as a member of the Photography club.
    • He's also a geek and interested in Magical Girl Pretty Miyuki.
  • Otaku: He's a fan of magical girl anime.
  • Real Men Wear Pink: He's a massive fan of magical girl anime.

Haruto Yuto
"I like the bikini model. She's my favorite character."

A first-year student at school, Class 1-1. He was once listed as a (temporary) member of the Science Club. His hair and eyes are red and he has the "Spiteful" persona — the only boy in school who did besides Borupen.

In an early video, he was used by the Dev to demonstrate what happens if a (male) witness to Yan-chan's killing spree is left alive the next day. Note that, due to the lack of differentiated personalities amongst the boys, all of them except the Heroes will react to her the same way. When the Rainbow Boys were given personas other than Teacher's Pet, the reaction will only apply to him sometimes, as Spiteful students won't care about someone they dislike getting bullied.

  • All Men Are Perverts: He agrees to check out the show that Sota has been recommending to him after Sota tells him that one of the characters is a "swimsuit model who's really busty". His favorite episode was the one where "they went to hot springs" and the bikini model is his favorite character and wants her to get more screentime in Season 2.
  • Cowardly Lion: He'll run away like a Loner when a student he doesn't hate is killed.
  • Evil Redhead: He has red hair and is a Spiteful student.
  • Evil Sounds Deep: He has a deeper voice than Sota.
  • Face–Heel Turn: A meta-example. Unlike his female counterpart Yui Rio, who has always been Evil, Haruto started as a perfectly normal Teacher's Pet before having his persona changed to Evil and then Spiteful.
  • Fiery Redhead: Shown multiple times throughout development.
    • He was originally in the Martial Arts Club before its real members were implemented in November 2015.
    • In that same build, he was used to demonstrate what happens if a boy witnesses Yan-chan commit murder and she gets away with it. He tells Yan-chan to her face that he's going to tell everyone he can what she did, which will constantly drain her reputation.
    • As of September 2017, he has been given the "Evil" personality type, which is fiery in its own way. This was changed in March 2018 to the "Spiteful" personality.
  • Hidden Depths: Apparently proficient in both textiles and fighting, as he was originally listed as a member of the Martial Arts club, then moved to the now-defunct Sewing Club.
    • Also, he is – as of September 2017 – Evil.
      • And, as of March 2018, it's been changed to Spiteful.
    • The conversations with Sota show that he has pretty high standards on anime and doesn't like it when shows start out bad just so they can surprise the audience later on.
  • No Sympathy: For anyone he hates and sees murdered.
  • Red Eyes, Take Warning: He has always had red eyes and has a "Spiteful" persona.
  • Spear Counterpart: To Yui Rio, much more so than the other boys are to their female equivalents. They have always been in the same class, usually in the same club (until Yui was moved to Cooking to test out the Framing mechanic), and are - as of October 2017 - the only two students in the entire game with Evil personas (which was changed to Spiteful in March 2018.
  • Token Evil Teammate: He's currently the only Rainbow Boy and male student with the Spiteful personality.


Ryoba Aishi
In 2020
In 1989 
"I said, use my first name, Darling."

Voiced By: Michaela Laws

The mother of our, um, "hero". Although not appearing during Yan-chan's exploits, as she and her husband are out of town for those ten weeks, many things are told about her in and out of game. Specifically, she kidnapped a senpai of her very own, making him develop Stockholm Syndrome, causing them to get married and have a child, who is none other than Yan-chan. Also, she may or may not have influenced Yan-chan's behavior.

  • Abduction Is Love: The Basement Tape reveals a number of important details – namely that she kidnapped her senpai and kept him locked up until Stockholm Syndrome kicked in, and that her mother had done the same thing to her husband.
  • Abusive Parents: Yes and no. She genuinely loves Ayano, and to our knowledge, has never been violent, neglectful, or even cruel to her. However, she's also actively trying to shape Ayano into her image, and spent the latter's childhood slowly manipulating her into the murderous yandere we get to know in the game. It's doubtful Ayano ever had a chance at a normal life, but if there ever was one, Ryoba knowingly robbed her of it.
  • Adorkable: Played with. Although she is a Yandere Serial Killer, she gives off this vibe, albeit in a very creepy manner; for example, her giggling girlish glee at being able to talk to her senpai is unsettling, but weirdly cute. However, it stops being any kind of cute when she threatens her senpai with a knife and then reveals she killed her rivals.
  • And Now for Someone Completely Different: Word of God says that a "1980s Mode" is planned, where you can play as her.
  • Arch-Enemy: The journalist. Also, Headmaster Kocho, in his own mind.
  • Ax-Crazy: Must've been this to some extent to kill someone for love.
  • The Bad Guy Wins: Got away with everything she did by manipulating the public's opinion of herself and the Journalist.
    • Although the outcome of her confrontation with the journalist in America during her ten-week-long trip remains to be seen.
  • Bitch in Sheep's Clothing: In the past, she put up the façade of an innocent schoolgirl when she was really just an obsessive murderer.
  • Boobs of Steel: She got away with murder in the past. That said, just look at her chest in the above picture.
  • Child by Rape: Implied, given that the yandere trait goes back several generations and she admits in the basement tapes that her mother abducted her father in the same way Ryoba abducted her senpai.
  • Consummate Liar: She managed to fool a court and the entire nation that she was framed for the murder she committed.
  • The Corrupter: She's slowly manipulating Ayano into becoming a yandere killer like herself, but Ayano can avoid becoming a murderer if she opts to go matchmaker. How Ryoba reacts to it is currently unknown, but it's possible she won't take this lightly and would assume Ayano is rejecting her heritage.
  • Creepy Child: Is able to fool numerous people and sabotages her crush's love life. She retains the creepiness into her adult years.
  • Cute and Psycho: Outwardly? A beautiful middle-aged lady who loves her family. Inwardly? Well, she does actually love her family, but she's also a murderous psychopath who kidnapped her future husband and kept him in her basement until he developed Stockholm Syndrome.
  • Dark Action Girl: Implied. It's established she stabbed the Phantom Girl to death, and the mention of her running around with a mop and bucket suggests that she wasn't the only person she killed. While she seems to favor a more subtle approach, it's safe to say she's willing to be more direct. A unique game mode focusing on her time at Akademi is also planned, where you can use similar abilities as Ayano.
  • Disproportionate Retribution: She killed one or more of her classmates for love, just like her daughter (has the option to). That's… a tad harsh.
  • Dissonant Serenity: Throughout the Basement Tapes, her voice is cheerful and giggly as she is talking to her kidnapped Senpai, and later when she plans to track down the Journalist. It's even emphasized by the full image of the above picture. Think she looks like a happy middle-aged woman? Well, note the knife she's holding behind her back.
  • Does This Remind You of Anything?: Her ecstatic sigh after she forces her sempai to use her first name sounds rather… orgasmic.
  • Doting Parent: She absolutely adores Ayano and can't wait for her to get a boyfriend of her own. Word of God states that Ryoba sees Ayano as, essentially, the personification of her and her husband's "love".
  • Emotionless Girl: It's heavily implied that like her daughter, she didn't experience emotions until she fell in love.
  • Empty Eyes: The Journalist describes them as soulless and doll-like.
  • Even Evil Has Loved Ones: She loves her husband and adores her daughter. Yan-chan is indifferent towards her, and her husband was forced to love her as an effect of Stockholm Syndrome.
  • Even Evil Has Standards: Word of God states that Ryoba's father was completely broken by her mother, to the point of being an Empty Shell devoted only to her. Ryoba actually felt pity for him growing up, and made it a point to not break Mr. Aishi completely. Say what you will about Ryoba, at least even she has her limits.
  • Evil Cannot Comprehend Good: When her sempai tries to reason with her to let him free, she's dumbfounded on why kidnapping and tying someone to a chair, let alone murdering people for love, is morally questionable.
  • Evil Matriarch: The Aishi clan is definitely a matriarchy, because its women kidnap, blackmail, and manipulate in order to literally "catch" a husband, whom they then terrify into submission.
  • Evil Virtues: She will have the same "Devoted" persona as her daughter. She equally illustrates why that can be a problem.
  • Eviler Than Thou: While the player has the option to make Yan-chan homicidal and dangerous, Ryoba is for certain homicidal and dangerous.
  • Exposition Fairy: YandereDev has considered making it possible for her to give you advice at the end of each week. Most of it would relate to reputation or avoiding a Game Over, said in the least incriminating way imaginable.
  • Faux Affably Evil: She seems like a friendly, loving, energetic woman. Key word being seems.
  • Generation Xerox: Not only is she a yandere like her daughter, her picture shows she looks exactly like Ayano, except older (duh) and, thanks to age and having a child, significantly more voluptuous. That they share a voice actress only further drives the point home.
  • Genki Girl: A rather creepy example.
  • Greater-Scope Villain: She is the reason the police are leery about investigating the school. Ryoba's psychosis being In the Blood is seemingly the source of Ayano's evil.
  • Giggling Villain: In Basement Tape #1 she's giggling a lot out of girlish glee for finally being able to talk to her senpai. Basement Tape #10, recorded decades later (mere days before the game's main campaign starts), shows she hasn't changed a bit.
  • Happily Married: Played with. While she is pretty happy she got together with her senpai, he is clearly not happy.
  • Hidden Badass: Possibly. She doesn't really look like a cold-blooded murderer, now does she?
  • Hypocrite: For a woman who called the Journalist a lecherous pervert, Ryoba herself is a Yandere Stalker with a Crush.
  • Implied Death Threat: Tells the journalist that it would be easy to make his death look like a suicide.
  • In the Blood: The first basement cassette suggest that her mother was also a yandere of sorts (or at least kidnapped her husband like she did). Word of God says that the yandere trait goes back several generations.
  • Karma Houdini: She was able to live happily with the man of her dreams and raise a daughter.
  • Like Mother, Like Daughter: You can invoke this if you play like the mother and kill others for love.
  • Like Mother Unlike Daughter: Ayano can invoke this if she goes matchmaker instead of Murdering the Hypotenuse. How Ryoba will react to this remains unknown, but it's speculated she won't take this lightly.
  • The Maiden Name Debate: Word of God states that her husband took her last name, and it's a family tradition. But would you expect anything else in a family of female yanderes who murder, blackmail, and kidnap in pursuit of propagating? Fun Fact! 
  • Manipulative Bitch: She manipulates people who try to get in the way of her pursuit of her senpai. She's also goading Ayano to become a yandere like herself.
  • Meaningful Name: In addition to "Aishi" already being explained under Yan-chan's entry, "ryōbo" is Japanese for "matron", and was changed to sound more feminine. A "ryōba" is also a type of handsaw.
  • Missing Mom: She and her husband are out of town for the 10 weeks that Ayano is running amok. Why is that? She's hunting the Journalist, since she discovered he was investigating her again.
  • Murder the Hypotenuse: It's unknown how many people she killed but she did kill the phantom girl. She must've gotten rid of at least a few girls this way, considering that she had to run around with a mop and bucket all day long, like Ayano does if she goes the killer route too.
  • Open-Minded Parent: Word of God is that if Yan-chan falls in love with a female Senpai, she'd just be happy that her daughter found love.
  • Predecessor Villain: She attended the same school her daughter did and killed at least one person during her time there.
  • Psychopathic Womanchild: The tenth basement tape makes it clear that she hasn't grown up one whit since she was a teenager. Still lovesick, still giggly, still enthusiastic, still an immature psycho murderer.
  • Punctuated! For! Emphasis!: She does this in Basement Tape #1 when the object of her affections won't call her by her given name because he's never spoken with her before.
    [sound of knife] "Say. My. Name."
  • Rape Is a Special Kind of Evil: Heavily implied. In Basement Tape #1, she is revealed to have kidnapped her sempai and held him against his will until Stockholm Syndrome kicked in. Between that and Basement Tape #10 (which takes place mere days before the main campaign of the game), they got married and had a daughter, which obviously means that they had sex. Considering how terrified Mr. Aishi is in those two tapes, it is highly unlikely that he consented to any advances. YandereDev has confirmed that this will be further explored.
  • Rapunzel Hair: Has it in her official design, as you can see. Art of her from her teenage years show even back then she sported a waist-length ponytail. It's the one major physical feature she doesn't share with her daughter.
  • Removing the Rival: According to the tapes, she got rid of some of her rivals through manipulation instead of straight murder.
  • Significant Double Casting: Shares a voice actress with her daughter, Ayano. See Yan-chan's entry for this trope for why it's significant.
  • Slasher Smile: The journalist described it in detail. It doesn't sound pretty.
  • The Sociopath: Hoo, boy. She's way worse than Yandere-chan. Other than her love of her daughter and husband (which is debatable all things considered), she is practically a textbook example. A manipulative liar who can be superficially charming, possess almost no empathy for anyone (with the aforementioned exceptions), and has very few morals allowing her to do just about anything to get what she wants.
  • Stalker with a Crush: She stalked her senpai for quite some time until she decided the best way to celebrate her acquittal was to kidnap him. She got what she wanted.
  • Strong Family Resemblance: Ryoba's concept art looks a lot like her daughter. The only differences are that Ryoba has longer hair, looks older, and has a noticeably curvier figure.
  • Terms of Endangerment: If you listen to the Basement Tapes, you'll hear her use the nickname "darling" quite a bit for her sempai.
  • Villain of Another Story: She was an obsessive stalker as well.
  • Villain Protagonist: She was a master manipulator and killer who got away with her crimes. She's also the protagonist of the planned "1980s Mode".
  • Villain with Good Publicity: She managed to convince the entire nation of her total innocence. The official characters page also describes her as someone who gets along very well with everyone in her neighborhood, even though she doesn't actually share much about herself.
  • Walking Spoiler: Just look at this page. You can already tell from the ratio of hidden text to normal ones that something's up with this chick. Saying anything about her at all aside from the fact that she's out of the country for ten weeks reveals at least half the backstory of the game.
  • The Woman Behind the Man: Not only was she a major influence on Ayano's behavior, but, since she is her mother, Ryoba is literally the reason Yan-chan exists.
  • Yandere: Like mother, like daughter. She killed at least one person who got in the way of her love-life in high-school and got away with it. Being Yandere seems to be matrilineal.

Mr. Aishi
Voiced By: Austin Hively

"Love?! But we've never even spoken to each other before!"

The father of our protagonist. He and his wife will be out of town for 10 weeks, so they cannot be interacted with during Story Mode. However, we find out plenty of information about them throughout tapes and Word of God.

  • Abduction Is Love: According to the Basement Tapes, Ryoba kidnapped him so that he could be hers.
  • Alone with the Psycho: In Basement Tape #1 with Ryoba. Poor guy.
  • Break the Cutie: Being held captive by Ryoba and forced to undergo Stockholm Syndrome has crushed his spirit.
  • Deadpan Snarker: Indulges in this at Ryoba's expense. This is probably a way to cope with his Stockholm Syndrome.
    Ryoba: Are you jealous, darling? Are you worried that someone is going to steal your beloved wife away?
    Father: That's… actually the last thing I worry about.
    Ryoba: Oh, darling! That's so romantic!
    Father: …right…
  • Distressed Dude: He was kidnapped by Ryoba and forced to love her. She got what she wanted in the end.
  • The Faceless: Unlike his wife, his sprite doesn't show his face. In fact, it's hidden by a glare of light.
  • Henpecked Husband: Played for Drama. He has a difficult time standing up for himself against Ryoba, even when she decides to take a long trip to America just before their daughter starts school. It's actually a more extreme case, since the relationship literally started when Ryoba kidnapped him, and she's been keeping an eye on him since.
  • Heteronormative Crusader: Zig-zagged, due to shifting Word of God. On the one hand, his instinct is to disapprove of his daughter in a lesbian relationship, owing to Japan's conservative views on homosexuality. However, upon reflection, he would probably encourage such a pairing, since it would likely mean the end of the bloodline of yandere Aishi women.
  • Hidden Eyes: His face in the picture frame is obscured by glare. That said, it's not hard to figure out how he looks since, like how Ryoba is designed to look like an older Ayano, he's designed to look like an older Senpai.
  • In-Series Nickname: Ryoba always calls him "Darling". Though if you listen carefully, she actually uses it to keep him under control.
  • Intergenerational Friendship: Word of God apparently stated that the various Senpais of the Aishi household share a close kinship with each other, as a way of dealing with their Yandere spouses. Presumably, he'll have this with Taro/Taeko after Yan-chan is successful.
  • Morality Pet: According to "Yandere-chan's Childhood," Ayano does care about him, at least a little, since she pretends to be happy and normal for his sake. Maybe her pity for him can't be equated to love but, for Ayano, that's huge.
  • No Name Given: So far, he's just called "Mr. Aishi". It's possible, like Senpai, that he will eventually get his own name.
  • Only Sane Man: Literally. We've got his Empty Shell Yandere of a daughter who might become a Serial Killer, his Yandere Giggling Villain of a wife who definitely became a serial killer, and.... this guy. Stockholm Syndrome aside, he comes off as pretty sane.
  • Overprotective Dad: But not to whom you'd expect. If he comes back from America and sees Ayano has caught herself a male Senpai, he – recalling how Ryoba turned his life upside-down and knowing firsthand what Aishi women are capable of – would be worried for Senpai. This is why when Ryoba expresses the hope that Ayano will have a boyfriend by the time they return, his reply is a dejected "I hope not."
  • Parental Abandonment: He and Ryoba are out of town for 10 weeks because Ryoba is hunting down the Journalist.
  • Parents as People: He desperately wants Ayano to be "normal" and is terrified of what she could become. However, it's clear he does love her, and spent her childhood taking her to doctors to try and treat whatever's wrong with her, giving her presents, and trying to make her happy. And, let's face it, him wanting Ayano to be different than all her predecessors is entirely justified of him.
  • Properly Paranoid: Since he knows what it's like to have a Yandere pursue someone, how could he not be worried about his daughter continuing the Aishi family tradition?
  • Rape as Backstory: Somewhat implied thus far. The first Basement Tape has him kidnapped by Ryoba, who keeps him captive until he "loves" her. In the present, he is still with her, but clearly is frightened of her despite them conceiving a child together. Worth mentioning is that even if he consented to any advances, it could still fall under Questionable Consent due to the circumstances of Ryoba being a Yandere who probably wouldn't take "no" for an answer. Word of God says the issue will be tackled fully in future Basement Tapes.
  • Sempai Kouhai: He was a year or two ahead of Ryoba in school.
  • Significant Double Casting: Shares a voice actor with (male) Senpai. See Senpai's Significant Double Casting entry for why it's significant.
  • Small Role, Big Impact: In the 'Why Yandere-Chan Lacks Emotions' video, Dev discusses him being the reason why Ayano will consider removing her rivals non-lethally, as he would do his best to raise her to be someone who wouldn't dare take a life.
  • Stockholm Syndrome: He's been held captive by Ryoba for so long that he can no longer stand up to her.
  • Token Good Teammate: He's the only good person in the Aishi household.
  • Unlucky Everydude: Let's see, a normal high school guy who was kidnapped by a yandere underclassman, forced to love her, (probably) forced to impregnate her with another yandere, and may be a witness to events repeating? He's the very definition of unlucky.
  • Walking Spoiler: For the same reason as his wife, because talking about him would reveal that Ryoba is also a Yandere.
  • Why Couldn't You Be Different?: For him, it's actually justified. He's frightened that Ayano will continue the family tradition, and would be happy if it turned out she was a "normal girl". That said, he still loves her and cares for her.

The Journalist

"I shouldn't have gotten involved in that case...with that girl. Pursuing her was the right thing to do...but if I hadn't involved myself with her, I'd still have a career."

Voiced by: Bradley Gareth

An former journalist who was investigating a string of murders on the Akademi campus in the 80's. He has recorded ten cassette tapes that are now scattered around the school grounds. Apparently, he wants his daughter to find them.

  • The Alcoholic: Became this after the court case.
  • Ambiguously Brown: Is clearly a shade darker than everyone else; this seems to be his natural skin tone, as opposed to Kyoshi and Asu, who have tans, and the bullies, who are spray-tanned like Donald Trump.
  • All of the Other Reindeer: The Journalist became this after the girl who framed him won.
  • Anguished Declaration of Love: In the last of his tapes before he tries to finally take down Ryoba Aishi, he uses the tape to tell his daughter that he loves her.
  • Arch-Enemy: Ryoba Aishi. He has spent years trying to bring her to justice, but she's Out-Gambitted him at every turn. We have yet to find out if they meet in America or (more importantly) if he'll finally succeed in his endeavors.
  • Badass Longcoat: He wears a trenchcoat. Justified because he wants to keep Ryoba from recognizing him.
  • Big Good: The closest thing this game has to having one. His entire character is trying to bring Ryoba to justice.
  • Clear My Name: Had to after the girl he stalked said he was a liar and a pervert.
  • Expy: A dark-skinned, trenchcoat-and-hat-laden, well meaning (but consistently-failing) lawful character who seeks to valiantly bring a criminal to justice? Are we talking about The Journalist, or Koichi Zenigata?
  • Fourth Date Marriage: He got married to his wife after six months of knowing her. This was because he was in a terrible place when he met her.
  • Hero Antagonist: He attempted to bring a murderer to justice. Unfortunately, his act of altruism ruined his life.
  • Hero of Another Story: He tried to do the right thing and failed. He might also be the Villain of Another Story, considering whose point of view we're looking from.
  • Hero with Bad Publicity: He got it after the girl he turned in was acquitted. He saw disgrace in every pair of eyes that looked at him. You see, he found out that a yandere girl was stalking an upperclassman and seemed pretty suspicious back in the 1980's. The Journalist stalked her and found out that she was constantly running around with a mop and a bucket as if she always had to clean something up. Not only that, but any girl that spoke to the stalked upperclassman got into deep trouble that separated them from the boy. So, after much convincing, the Journalist was able to get the yandere taken into custody. Despite the evidence the Journalist found, the yandere girl managed to slip away with some very persuasive acting. Because of this, the Journalist has been notorious for being a "pervert" and a "glory-hound".
  • I Can't Believe a Guy Like You Would Notice Me: He admits he has no idea why his wife married him.
  • I Did What I Had to Do: He's prepared to let the murderous woman claim one more victim just so he can have proof of her guilt. However, the Journalist slipped up and now he has to flee the country. And our good ol' buddy Ryoba follows him.
  • Intrepid Reporter: Perceptive enough to spot a yandere's actions and brave enough to try to bring her to justice. Unfortunately, he just happened to pick the wrong target...
  • Inspector Lestrade: Taken to its logical conclusion; He had all the evidence at the ready to prove Ryoba was behind the Akademi murders, but had his reputation completely tarnished by her cleverly-manipulative actions at the time of judgment.
  • Maternal Death? Blame the Child: He found it hard to love his daughter after his wife died giving birth to her.
  • Mistaken for Pedophile: One of the reasons why Ryoba was acquitted was because she claimed that he was a lecherous pervert. Ironically, Ryoba herself is a Stalker with a Crush, though for someone slightly older than her.
  • My Greatest Failure: He considers interacting with the yandere from the tapes to be this because she ruined his reputation.
  • No Good Deed Goes Unpunished: He found out who the murderer was and accused her, but without proof, he was laughed out of court and lost his job.
  • Not What It Looks Like: He stalked a schoolgirl in an attempt to collect proof of her misdeeds. Thing is, the way he makes it sound, it seems like he genuinely had good intentions at heart. He was also right, considering that very same girl threatened him with death. She said straight to his face that she could easily make his death look like a suicide.
  • Parental Neglect: He never really cared for his kid because he slightly blamed her for his wife's Death by Childbirth. His daughter basically had to raise herself after he fell into depression.
  • Run or Die: After being confronted by the murderous woman the second time after 20 years, he panics and leaves the country, wondering whether she's crazy enough to follow him. She is.

The Journalist's Wife

The woman who met the Journalist while he was in a slump and married him soon after.
  • Clingy Jealous Girl: Around her man. She hated seeing him with other women.
  • Death by Childbirth: She died giving birth to her first child.
  • Fourth Date Marriage: Got married to her husband after six months of knowing him.
  • Green-Eyed Monster: She got envious and jealous every time she saw her man talking to another woman.
  • Living Emotional Crutch: To her husband, since no one else liked him.
  • Manic Pixie Dream Girl: She brought happiness and light into the Journalist's life when he was feeling down. On the flip side, she wasn't all that stable and he has his doubts about her reasons for getting close to him.
  • Posthumous Character: She died over 15 years before the main story.
  • What Does She See in Him?: It's unknown why she liked the framed journalist who had lost all credibility. Even he has no idea.
  • Yandere: Heavily implied to be one for The Journalist, albeit the most downplayed and sympathetic example so far.

Mr. Ronshaku

"You scumbag! What have you done to my daughter?!"

Voiced By: Kellen Goff

The owner of Ronshaku Loans, and Musume Ronshaku's father. He is a notorious loan shark and is a terrible and terrifying person to everyone except his daughter.

  • Adult Fear: He ends up on the receiving end of it when his daughter (who he's shown to love dearly) goes missing, and the next thing he sees of her is that she's tied up, blindfolded, and begging for help. Even if she returns home safely, she's traumatized for life, going from an outgoing, talkative girl to a reclusive, quiet, shell-shocked mess. Even for a Loan Shark, that's gotta sting.
  • Doting Parent: He spoils his daughter rotten.
  • Eviler Than Thou: This piece of filth has nothing on Yan-chan.
  • Even Evil Has Loved Ones: He's a ruthless Loan Shark who makes unscrupulous deals and threatens his clients with violence, but he genuinely cares about his daughter and doesn't hesitate to compromise his business when her life is threatened.
  • Guttural Growler: He essentially growls his lines during the voiced text message segment. This both highlights his evil nature, and how angry he is about his daughter being kidnapped.
  • Loan Shark: Predatory loans are what his whole business is about.
  • Papa Wolf: If you kidnap Musume, you'll find that he'd do anything to get her back. He doesn't hesitate to release all his clients from debt to get her home safe.
  • Punny Name: Ronshaku is Engrish for Loan Shark.
  • You Monster!: He says this verbatim when Yan-chan threatens to remove a finger from his precious daughter for every day that Ronshaku Loans keeps its clients in debt.
  • You're Insane!: He calls Yan-chan insane when she tells him to release all debts while negotiating the safe return of his daughter.

"The Yakuza"
A potential character discussed in the August 1st, 2017 video. He is the older brother of one of the male 1980s Mode delinquents, involved in the Yakuza (Japanese organized crime). He will fulfill a similar purpose to Info-chan- granting the player favors and playing a part in some elimination methods. However, his services and demands are far more extreme than hers- the Yakuza has access to weapons, hard drugs, and other extremely illegal things, and you pay him by kidnapping people and handing them over to him. If you do enough of this, he can kidnap (and thus eliminate) your rivals for you. Ryoba can gain access to his services by doing a big favor to his younger brother, who will then commend her to him. The first favor will be for free, as thanks for helping out his little brother, but the rest will most definitely not.
  • Arms Dealer: Among other things, he deals in weapon trafficking, and can supply Ryoba with some of them.
  • Deadly Euphemism: If the sample text given for his abduction of Osana is anything to go by, this is how he would communicate with Yan-chan. Justified, since both he and Ryoba would want plausible deniability if someone were to stumble upon their correspondence.
  • Drugs Are Bad: He can supply Ryoba with hard drugs to use to deal with her Rivals.
  • Even Evil Can Be Loved: For all his awful deeds, he has a little brother that thinks the world of him and wants to be just like him. The affection is mutual, though the Yakuza would much prefer it if his brother didn't follow in his footsteps.
  • Even Evil Has Loved Ones: He's willing to do Ryoba a big favor at no cost because she helped his little brother with something. He's also dedicated to keeping his brother's living situation comfortable, and genuinely wants him to stay on the straight-and-narrow.
  • Even Evil Has Standards: Yandere Dev toned down the gruesomeness of the Yakuza's services for both gameplay and story purposes some time later. His demand for kidnapped victims as currency for harvesting or trafficking would cause the player to rapidly run out of victims to kidnap and lead to a game over, thus changing it to holding students hostage for ransom. Yandere Dev also explored the possibility of earning his services if the player helps reform his younger brother away from delinquency. In story, Yandere Dev has explored different possibilities, such as the Yakuza believing in a warped sense of justice or only taking part in such villainy because he has no choice in the matter.
  • Evil Brother Wants Good Brother: A non-lethal way to get payment for his services is to set his younger brother on the straight-and-narrow path, as he doesn't want his brother to get involved with crime like he does.
  • Evil Counterpart: To Info-Chan, though it's more like eviler counterpart. He, like her, serves as a shopkeeper- but while Info-chan serves as an information broker and only flirts with illegal behavior, he is a criminal stated to be involved in theft, murder, organ trafficking, and human trafficking. Info-chan just wants panty shots to sell to perverted schoolboys (and possibly blackmail material), the Yakuza initially requested live victims (and possibly snuff films), who he is suggested to either harvest for their organs or sell into sexual slavery. This was later changed to kidnapping student so that he could hold them for ransom.
  • Eviler Than Thou: He makes every other evil character in the story look like a harmless pussycat by comparison. (Next to maybe Ayano, depending on how you play her.) Even Info-chan. Especially Info-chan. This was eventually toned down, though he's still unmistakably a criminal.
    • Especially so with Osoro and Megami, nominally influential and powerful rivals, who the Yakuza can just flat-out kidnap and send off to their fate. However, the yakuza will be I. 1980s mode, so he won't kidnap Osoro or Megami.
  • Greater-Scope Villain: He's a member of organized crime who's involved in drug dealing, murder, larceny, organ theft, and human trafficking, among other things, and has probably killed more people than Ayano will ever have a chance to in-game. But in regards to the player, he's just a source for some... extreme services.
  • Hitman with a Heart: He's part of an organized crime family, and the payment for his services is live victims that he could harvest for organs or sell as a sex slave. With that said, the man adores his younger brother, and would do anything to keep his brother safe. On that note, Yandere Dev has said that it may be possible that he would rather kidnap the students and hold them for ransom, rather than do something as heinous as the aforementioned method.
  • Knight Templar Big Brother: YandereDev describes him as someone who's willing to do anything to make sure his little brother is safe and happy. "Anything" includes organized crime and kidnapping people. He's even suggested to be a Yandere in his own way, even if his feelings are more familial than romantic.
  • A Lighter Shade of Black: If Yandere Dev's ideas for his backstory, motivations, and personality come to pass, he'll be this to Ayano. He's still a ruthless criminal, but he has understandable reasons for what he does, he truly loves his little brother and doesn't want him to follow down the same path, and he has something of a moral code — something Ayano does not.
  • Morality Pet: The love that this asshole has for his brother is his only redeeming factor.
  • Nothing Is Scarier: What does he do with the people you kidnap for favors, or the rivals you sic him on? It could be Organ Theft, or sex slavery, or perhaps something even worse. All we know is that you've just handed a person over to a shady member of organized crime, and that it'll probably mean something bad.
  • Only Known By His Nickname: So far, he's just "the Yakuza." YandereDev has said he simply doesn't have a name yet.
  • Organ Theft: YandereDev states that he's involved in organ trafficking.
  • Secret Shop: When you get down to it, he's basically this. Whereas Info-chan basically contacts you herself and requires relatively simple-to-get currency in exchange for simpler services, the Yakuza is only accessed after a Side Quest is completed, and offers more powerful tools and outright elimination of rivals in exchange for a much harder to acquire "Currency".
  • Sex Slave: Suggested to be what he might do to the people you kidnap for him.
  • Snuff Film: It's implied he controls part of a market of them, and Ryoba might be able to send him Snuff Films, instead of sending him kidnapped students, in exchange for his "services".
  • Tattooed Crook: He has a snake tattoo visible on his arms, like any true member of the Yakuza.
  • Trapped in Villainy: His backstory video suggests that one of his parents died, forcing him to take up crime to support his younger brother since conventional jobs weren't enough to get by. It's also suggested that his boss threatens his younger brother to make sure he follows his orders.
  • Vigilante Man: One of the possible motives YandereDev has planned for him is to make it so that he only targets corrupt authority figures such as Dirty Cops and Corrupt Corporate Executives, and harvest their organs so that they can actually be of some benefit to society. The way Ryoba would manipulate him into kidnapping the rivals in this case is by deceiving him and making him think the rivals are just as bad as the people he targets.
  • Villain of Another Story: Sympathetic qualities aside, when not helping Ryoba in her schemes, he's still busy conducting his criminal business elsewhere.
  • Waistcoat of Style: He wears one, and generally seems to prefer a formal dress sense. This is actually accurate to real life, as Yakuza members are known for wearing nice suits.
  • Would Hurt a Child: He's perfectly fine with kidnapping high school students to do who knows what.
  • Yakuza: What he's a part of. If he's implemented, he can use his connections to help out Ryoba.


A fan of a fictional game called Moonlit Warrior Selene who regularly chats with you upon finding their server.

    Saikou Corp (MAJOR SPOILERS) 

As a whole
  • Acme Products: They are omnipresent throughout the game as it's harder to name things at Akademi that don't have the Saikou corp logo on them!
  • Big, Screwed-Up Family: You've got Saisho, who drove off his eldest daughter when he put her through extreme training to inherit his company and may have had his third child erased from reality, you've got the father, who pretty much had his childhood come crashing to a halt when his sister walked out on them as described earlier, and you've got Megami and Kencho, who have a severe rivalry, to the point that Kencho dearly wishes some horrible misfortune would befall his sister so that he can take the company.
  • Evil, Inc.: Are hinted to be behind some nefarious plot that somehow involves Yandere-chan.
  • Mega-Corp: Described as the most powerful business conglomerate in Japan. Its products are everywhere.

Saisho Saikou
The founder of Saikou Corp. and its CEO in 1989, and the founder of Akademi High. Plays a critical role in the backstory.
  • Abusive Parents:
    • He groomed his daughter from early childhood to assume control of his financial empire, freaked when she refused, and almost certainly did the same to his son afterwards.
    • Fun Girl's first hidden message implies that he used her, his own daughter, as the first human guinea pig to prove a machine he invented was safe to investors, retgoning her and shattering her across time and space. As of April 2, 2018, her message implies he did away with his daughter on purpose to keep her from exposing him for something.
  • Awful Wedded Life: Not necessarily awful, but there was little love between him and his wife, according to YandereDev. His son, however, loves his own wife, and Megami would prefer to marry someone she loves if possible.
  • Broken Pedestal: Kocho Shuyona used to have nothing but respect for Saikou. Then he found out he had been grooming his daughter since childhood to inherit the company and disowned her when she refused to follow his demands. Needless to say, he couldn't look at him the same way ever again.
  • Control Freak: Kocho Shuyona describes him as someone who refuses to compromise and only accepts the results he wants.
  • Corrupt Corporate Executive: Willing to put his daughter through an insane training regimen from early childhood in order to ensure he has an heir to his company.
  • Evil Cripple: Due to old age, he uses a wheelchair.
  • The Ghost: While he is important to the backstory, he does not appear in gameplay.
  • I Have No Son!:
    • He disowned his daughter when she refused to inherit Saikou Corp, and they haven't spoken in 30 years.
    • Taken Up to Eleven with his other daughter, whom he more-or-less erased from existence in order to keep her quiet.
  • Patriotic Fervor: According to FUN-Girl the Japanese Empire was to him what Taro Yamada is to Ayano Aishi.
  • Posthumous Character: Possibly; YandereDev originally meant for him to be dead at the start of the game, but realized that would lock him out of "certain story possibilities".

Megami’s Aunt

Mr. Saikou
The current CEO of Saikou Corp and the father of Megami and Kencho.
  • Arranged Marriage: Was put in one to Megami's mother.
  • Corrupt Corporate Executive: Is part of an as-of-yet unknown conspiracy with the headmaster involving the school and Ayano. And is at least known to use bribery to meet his goals.
  • The Faceless: As seen above, his artwork shows him from behind.
  • Freudian Excuse: His actions might have to do with how his childhood was cut short after his sister left and he was put through an advanced version of her training. The fact that Kencho was made aware that he's a backup to Megami means that the fact that Mr. Saikou was a backup to his sister was something he didn't know.
  • Wine Is Classy: Invoked in his character image.

Kencho Saikou
Megami's younger brother and the backup heir to Saikou Corp should Megami die or abandon her duties to Saikou Corp.
  • Annoying Younger Sibling: He needles and discourages Megami at every opportunity.
  • Black Sheep: To a degree. It's mentioned that the Saikou family strives to be honorable, respectable and dignified, and he's none of these things.
  • Cain and Abel: Is hinted to be plotting against his sister to take over Saikou Corp.
  • Can't Catch Up: No matter how hard he tries, his sister always outdoes him.
  • Expy: Let's see, a younger member of a large organization? Meant only to be a backup in case the original dies? Isn't seen as an individual with his own merits, and only as a backup? Sounds quite abit like Beyond Birthday aka BB.
  • Foil: To Hanako. While Hanako adores her big brother and doesn't want to share him with everyone else, Kencho despises Megami and wants nothing more than to replace her as the Saikou heir.
  • Freudian Excuse: His behavior and character are tied to the fact that he's fully aware that he's just a backup to Megami, making him feel like he lacks purpose unless he can outdo her.
  • Generation Xerox: He looks very similar to his father, and YandereDev states that "he imitates his father to try and gain his favor".
  • Inferiority Superiority Complex: He lives by comparing his accomplishments to Megami's, which amount to diddly-squat because she outperforms him everywhere leading to a severe case of this. The superiority part comes in when it's mentioned he flaunts his wealth and status over anyone he considers beneath him as a coping mechanism.
  • Satellite Character: His entire identity and sense of self-worth is tied to his relationship with Megami.
  • Sibling Rivalry: Has an extreme one with Megami; he wants to surpass her in order to earn his father's love, but she always outdoes him.
  • "Well Done, Son!" Guy: He wants his father's approval more than anything else.

"Die, monster! You don't belong in this school!"

Voiced By: Michaela Laws

The protagonist of Yanvania: Senpai of the Night. She is a student of the Akademi Institute, a boarding school that teaches magic for young men and women who have high potential to become witches and wizards. The upperclassman who she has a crush on resurrected the powerful succubus Dracula-chan, causing all the students to disappear. Beldere-chan must defeat Dracula-chan before the sun rises, for if the quest is failed, the students will be lost forever and Dracula-chan will achieve full power.

"What is a Senpai? A miserable little pile of heartbreak! But enough talk...have at you!"

Voiced By: Cayla Martin

Yanvania's antagonist. Every 100 years, Dracula-chan will rise from her grave, begging for a blood tribute from a upperclassman at Akademi Institute. If the student complies, all of the students will disappear. Only a young woman who was in love with the upperclassman can defeat her.

  • Adaptational Villainy: She looks a lot like Sakyu Basu from the main game. However, unlike Sakyu, who seems like a fundamentally decent person, Dracula-chan has no qualms about making every student bar the upperclassman who made the pact with her disappear.
  • Female Misogynist: Implied to be this. When Beldere-chan accuses her of stealing boys' hearts and making them her slaves, she responds with "perhaps the same could be said of all girls".
  • Horny Devils: Though more vampiric than most examples.
  • Our Vampires Are Different: She's technically a succubus, rises only once every 100 years, and it's not specified if this blood tribute involves actually drinking blood. There's also all her magical powers. She is, of course, based on Castlevania's Dracula.
  • Stripperiffic: Her costume doesn't leave much to the imagination, befitting a succubus.
  • This Cannot Be!: Says the phrase word for word as Beldere-chan kills her.


The heroine of Magical Girl Pretty Miyuki. She's the most popular girl in her school, but that doesn't mean too much when most other magical girls are celebrities with audiences of millions.

  • Always Female: Only women can see the monsters that magical girls face.
  • No Respect Girl: Most other magical girls don't take Miyuki seriously, since she's so weak compared to most of them.
  • Pink Is Feminine: She has a pink color scheme, as is traditional for magical girl heroines.
  • Popularity Power: It's what empowers magical girls, and while Miyuki has a lot of it for a high schooler, compared to pop idols and other international celebrity magical girls, it really isn't much.
  • Weak, but Skilled: Miyuki doesn't have the raw power that other magical girls have, since she's only a high schooler.


"Who is he? Why is his head on fire??"
"...and why do I feel like seriously making out with him?"

The protagonist of the April Fools' Day Dating Sim spinoff, Burning Love. She (or he) is a student who encounters the Flame Demon in the Occult Club room and tries to "woo" him.

"Your idea of fun seems very very interesting."

An Easter Egg character that can only be accessed by altering the game files in specific debug builds – in the 2016-02-01 build, she would converse with the player in a series of text messages telling her story; in the January 2017 builds, she scolds players who modify the game files to try accessing unfinished content. In both cases the game intentionally crashes after she's had her say. She does not appear in an unmodded game, but she can be seen on the official website in another Easter Egg.

  • Adult Fear: You are so confident you are right you test your machine on your daughter, and then she is not only killed but at the same time living yet molecularly deconstructed and blasted across spacetime. Now imagine you can't even remember doing so, and she is watching every universe with you in it, and your children won't remember their sibling.
    • Subverted with the implication that she is the missing third child of Saisho Saikou, and was murdered to prevent her from exposing company secrets.
  • Expy: Of Dr. W. D. Gaster from Undertale. Both were involved in experiments that caused them to break across time and space. Both existing and having never existed in the multiverse. Furthermore, in recent builds trying to access her will spark the message "But nobody came." Her appearance, black background, speaking style (white text that appears letter by letter), and performing a mild Jump Scare before crashing the game also somewhat resembles Chara at the end of the Genocide route.
  • Gratuitous Japanese: In both of her extant Easter Eggs, the same Japanese phrase appears, which roughly translates to…
    "My, my. Who are you? Nice to meet you. We're going to have a lot of fun together."
  • Interface Screw: In the January 2017 builds, if the player alters the game's code to try to spawn Osana, FUN GIRL will chase Ayano and, when she catches her, cause the game to crash. When the game is re-opened, FUN GIRL will hijack the title screen to scold the player for messing with the game's files.
  • Konami Code: Go to the Characters page on the game's website and punch in the code to get a look at her.
  • Nightmare Face: She has white skin and hair, and black gunk coming out of her eyes and (smiling) mouth. Overall, she's not pretty to look at. Her January 2017 appearance also gives her some some exaggerated expressions, as well as a brief blank face.
  • Nightmare Fuel Station Attendant: Besides her terrifying origins, there is her creepy appearance, her somewhat sinister dialogue, and her morbid fascination with Ayano/You.
  • No Fourth Wall: In the January 2017 builds, she addresses the player to chastise them for hacking the game in order to spawn Osana, saying that YandereDev asked her to prevent players from doing so, then notes that the player will find some way around her due to being the type of person who edits game files.
  • Ret Gone: Her fate in-universe. Until the website Easter Egg this was her fate out-of-universe too.
    • There is a hint in-game that seems to imply her sister does remember her in some capacity, and is trying to find her. She has even abandoned her position as the heir of Saikou Corp. to do it.
  • Slasher Smile: Most of her facial expressions during her appearance in the January 2017 build fall into this category.
  • Tainted Veins: Her website appearance has these visible on her arms and legs.
  • Unreliable Narrator: Admits in the April 26, 2018 build that she lies sometimes, because she finds it fun since "YOU EAT UP EVERYTHING I SAY."


A potential male version of Yandere-chan. He isn't officially in the gamenote , but if he was, he would have two possible personalities – the first would be a basic gender-bend of Yan-chan, with him having been emotionless until he met Senpai and felt emotions for the first time; the second would have him as a sadist who needs an obsession to feel complete. This Yan-kun would be very possessive of Senpai and would try to kill his rivals because to him, it's a fun game of death.

Note that YandereDev has stated many times he personally finds the idea of a male yandere murdering a bunch of schoolgirls incredibly distasteful. However, he also said it would make for a decent Kickstarter stretch goal, and persistent goading from fans led him to place the concept on the website's "Characters" page.

  • Audience Surrogate: One of his possible personalities treats his evil like a game. That said, he's a potential Player Character in this video game.
  • Awesome, but Impractical: The reason he's not in the game despite some fans' desires is because creating a male Yan-chan would mean redoing all her animations and lines for the male body and voice.
  • Depraved Bisexual: Like Yan-chan, he'll vie for Senpai no matter what gender Senpai is. That said, one possibility for his personality emphasizes the depraved part more.
  • Emotionless Girl: One possibility is for him to be a male version of this, just like Yandere-chan.
  • Eviler Than Thou: A possible interpretation of Yandere-kun's alternative personality. Yandere-chan is expressly stated to be emotionless (except when Senpai is involved) and takes no pleasure in killing. Yandere-kun's alternative personality portrays him as a sociopath who sees the whole thing as a game (which it kinda is).
  • Leaning on the Fourth Wall: The Sociopath personality has him thinking all of his evil surrounding Senpai as like a game. That said, if he ends up in the game as an alternate Ayano, he'll be the Villain Protagonist of a game.
  • More Deadly Than the Male: Inverted. One of his possible personalities is merely a Gender Flip of Yan-chan, and the other is Eviler Than Thou to her.
  • Psychotic Smirk: An early version of the mod had him with a constant, serene smile on his face, which turned into this whenever he was in the middle of murdering. This was taken out in a later update.
  • Sadist: While Yandere-chan eliminates rivals so that she won't be left without the one thing that brings her happiness, Yandere-kun (well, one possible personality for him) hunts them because he finds it fun.
  • Spear Counterpart: He's this to Yandere-chan.
  • Yandere: Just like his female counterpart.


A girl who hunts down Ayano in the Mission Mode. She pretends to be a normal student until her prey is within striking distance, and relentlessly pursues her target.

  • Ambiguously Evil: She's definitely a killer, but it's not clear if she's an assassin for hire, a bodyguard who just uses excessive force, a vigilante who pays evil unto evil, or someone who is trying to get revenge on Ayano for something bad she did to her in the past. As a result, she could be either a Psycho for Hire, a Noble Demon, or an (anti) hero antagonist.
  • Conspicuous Gloves: She always wears black gloves, unless the player has chosen to have her disguise herself.
  • The Dreaded: Info-chan recognizes her (eventually), and warns Ayano to avoid her, showing that her reputation is well-known enough that Info-chan knows she is not to be trifled with.
  • Eerie Pale-Skinned Brunette: Her default appearance has pale skin, wavy black hair, and "haunting" red eyes — making her look like a vampire.
  • Expy: She's described as operating in a similar manner to SA-X from Metroid Fusion.
    • She has also some similarities with Agent 47 like wearing black gloves, having a disguise skill, being silent and having a perpetual Kubrick Stare expression.
  • Master of Disguise: An option in the Mission Mode menu gives her the ability to assume the identity of another female student. If she does this, she'll blend into the crowd so perfectly that Ayano won't see her coming unless she's on-guard. Oh, and which girl's identity she assumes is random. If you take a photo of her in-disguise, though, Info-chan will notice that something's off.
  • Mighty Glacier: She can't be beaten in a fair fight – on harder difficulties, she can't be beaten at all – but unlike Ayano, she never runs (she walks faster than Ayano, though).
  • Multiple-Choice Past: She could possibly be a bodyguard, a rival assassin, or someone with a personal vendetta against Ayano.
  • No-Sell: Masks are completely useless against her. She will know it is you.
  • Only Known by Their Nickname: Assuming that "Nemesis" isn't her actual name.
  • Peek-a-Bangs: Her second hairstyle.
  • Pet the Dog: YandereDev states here that in the modes where Nemesis disguises herself as another female student, he assumes that she simply knocked the student out and stuffed her into a container to take her place, as he does not think she would kill her.
  • Red Eyes, Take Warning: She has "haunting" red eyes that accentuate her eerie appearance and the fact that she's a killer even more dangerous than Ayano.
  • Serial-Killer Killer: She's hunting Ayano, who is a Professional Killer in the Mission Mode.
  • Silent Antagonist: As of current builds, she does not speak. Justified, as she has nothing to say to her target, is too busy with her mission to talk to anyone else, and has no reason to talk to herself.
  • The Stoic: She has a serious expression on her face at all times.


The protagonist of the manga and anime series Life Note after coming across a notebook that allows her to control peoples minds, she resolved to use the notebook to orchestrate the deaths of horrible people.

  • Adaptational Heroism: Unlike the Kiras in Death Note who killed innocents without remorse, Yamiko has a small breakdown after using her notebook to kill a policewoman who came too close to discovering her identity.
  • Composite Character: She shares Light’s role as the protagonist but also dresses in Misa’s gothic fashion.
  • Expy: Of Death Note's protagonist, Light.
  • Heroic Albino: In theory, anyway; she's an albino and uses her Life Note to kill criminals.
  • It Only Works Once: She can only use the Life Note to control any individual once, regardless of whether or not they are still alive afterwards.
  • Meaningful Name: Yami is a Japanese word for "Dark", fitting for the protagonist of a Death Note parody, who has a protagonist named "Light".
  • My God, What Have I Done?: Her reaction to killing Detective Seto.
  • Necessarily Evil: What she tells herself afterwards.
  • Pædo Hunt: Among the targets of her crusade are child molesters.
  • Psychic-Assisted Suicide: Against the detective and possibly others.


The protagonist of "Mandere Simulator", an April Fools' Day version of the game. He takes Ayano's place as the Player Character.
