"Can I... help you?"

Voiced by: Austin Hively (Taro)

Senpai is a regular senior-year student at Akademi High who inadvertently becomes the target of affection for Ayano-chan and nine other females at the schoolnote . He (or she, eventually) is 19 years old, has a "Loner" personality, and is in Class 3-2.


  • Ambiguously Bi: An interesting meta example with the ambiguity coming from whether Ayato - Ayano’s potential male form - will ever be included in the game beyond an Easter Egg. If he is, then Senpai’s sexuality would change to accommodate this in both their male and female forms. Taro going from a straight man to a bisexual one, and Taeko changing from a Lipstick Lesbian into a bisexual woman.
  • Author Avatar: In Fall 2015, became one of YandereDev for a while (replacing Ayano), until Dev got his own unique avatar that looked somewhat different from Senpai several months later.
  • Berserk Button: He finds people who commit crimes while wearing masks to be especially cowardly, and will attempt to rip your mask off if you kill someone in front of him wearing a mask, even at the expense of his own safety.
  • Beware the Nice Ones: YandereDev states if he's pushed too far and he finds out that Yan-chan was the cause of all his torment, it doesn't end well… as we see Senpai grab a knife.
    Yandere Dev: I wonder, what if Senpai was driven to the very edge of sanity, and then he learnt that you were the one that forced him to watch his sister die… what would he do?
  • Big Brother Instinct: It's implied that he will have this to his little sister once she's implemented in the game.
  • Big Man on Campus: Downplayed. At first only the most average girls will like him, but each subsequent rival is more popular, important, strong, or otherwise difficult to defeat than the previous one.
  • Blessed with Suck: He has the ability to instantly attract a harem of girls who all want to be with him. Too bad one of those girls is a yandere.
  • Brainy Brunette: Played with. He has black hair by default and is frequently seen reading a book at the fountain during the morning, implying that he's a bit of a bookworm, but if Info-chan's comments in the Student Info are anything to go by, his grades (like everything else about him) are average.
  • Break the Cutie: He has close relationships with two of the rivals (Osana Najimi and his younger sister), and the developer has stated that the way they disappear from his life may give him serious mental problems by the end of the game, including PTSD. Even if rivals are dealt with non-violently, it appears he'll either suffer trust or abandonment issues, depending on the methods used.
  • Broken Bird: Like Yan-chan, Senpai has a sanity meter. Unlike hers, his isn't visible. It will be damaged if he witnesses something disturbing. note  Heaven help you if he finds out that you killed his best friend and his little sister when he has low sanity… It's been confirmed that just how much damage you do to his loved ones will affect the kind of ending you get, possibly including his committing suicide.
  • Call to Agriculture:
    • The information Info-chan gives you on Senpai is rudimentary at best, but he is known to enjoy spending time outdoors in Akademi's courtyard. His interactions with Osana seem to confirm that he enjoys spending time in nature. Indeed, YandereDev has stated that if none of the rivals or Yan-chan existed, he would probably end up with the President of the Gardening Club. He can also be seen on the school's Fakebook page asking about the age of the cherry trees on the main path to the front gate in old debug builds before it was changed to Sakyu who asked the question.
    • Early in development, fans who delved into the game files discovered he was in the Gardening Club, as it was the original "null" club stat. These days, he is in no club. YanDev has said that Senpai will never join any club during the course of the game, though he'll drop in on several.
  • Canon Name: While YanDev stated at one point that he'd like players to be able to change Senpai's name, the character bio on the official site states that the male and female variants are canonically "Taro Yamada" and "Taeko Yamada" respectively. That said, unless Hanako's surname gets programmed to change to whatever is set as Senpai's surname, the Yamada surname will be consistent despite renames.
  • Childhood Friends: With Osana Najimi.
  • Conveniently Seated: YandereDev jokes that he has "the main character chair" – seated in the back next to the window. Sure enough, in the redesigned school (where the students finally sit at their desks), that's where his desk is.
  • Cool Shades: You can give him a pair when you're customizing him.
  • Covert Pervert: When someone asked whether he'd really accept the Nurse's feelings on Twitter, the Dev replied by basically implying that he might have a nurse fetish.
  • Cowardly Lion: Senpai has a variant of the "Loner" persona, meaning his reaction to seeing a dead body is to run off campus to call the police. In addition, many of his quotes upon seeing Yan-chan doing something… unsavory have him react with shell-shocked horror. However, if Senpai sees you kill a rival while wearing a mask, he'll rip it off you personally to expose your identity.
  • Clueless Chick-Magnet: For someone who started the game not being very popular, senpai will somehow attract the attention of a surprising number of people, who will serve the role of the rivals Ayano must get rid of. S/He's utterly clueless as to why these people are attracted to him/her, not the least of which Ayano.
  • Dead Alternate Counterpart: In the Mission Mode Alternate Continuity, his death by the hands of Ayano triggers the transformation of his little sister Hanako into the ruthless killer Nemesis.
  • Disappointed in You: In the "bad reputation" ending, as you are surrounded by giggling girls, he gives you a Disapproving Look, shakes his head and crosses his arms.
  • Distressed Dude: If the player chooses to go for a kill everyone route in the demo, Yan-chan will kidnap Senpai as soon as everyone else is dead. The last scene shows him tied up, gagged and blindfolded on the chair in her basement.
  • The Dog Bites Back: YanDev has mused the possibility of Senpai actually killing Yan-chan himself, should he lose enough sanity and discover that she (that is, you) caused the death of a loved one – his sister mentioned specifically – in front of him.
  • Even the Girls Want Her: Presumably the case if you decide you want a female Senpai, since you and the potential suitors will still be female.
  • Everyone Calls Him "Barkeep": While you can name him whatever you like, he's typically referred to as Senpai.
  • Everyone Has Standards:
    • Nice as he is, there are limits to what he'll take. If you stand near him too long, he'll get creeped out and eventually ask you to go away, triggering a game over. And he also (obviously) won't react well to any signs of Yan-chan's true murderous nature. Adding on to this, he'll be repulsed if he sees Yan-chan taking panty shots.
    • He has a strong sense of justice, and hates people who commit evil behind a veil of anonymity. The sight of a masked murderer would fill him with disgust and cause him to disregard his own safety and unmask the murderer at all costs.
    • On a darker level, in the final game, he will not accept a love confession from a rival who has a sufficiently bad reputation. This also extends to you.
  • Extreme Doormat: He's portrayed as a pushover in response to how his tsundere friend Osana Najimi treats him, as well as his own little sister (he'll actually agree if she demands he not get any girlfriends, for example).
  • Fetish: YandereDev has implied that he might have one for nurses.
  • Flat Character: Justified, as he's not supposed to be a complex character. He is a completely average and normal guy.
    "An average student. Average grades, average look, average life… I'm not sure what you see in him." - Info-Chan
  • Foil: To Jokichi Yudasei, While Jokichi is powerless against Ryoba and doesn’t try to defend himself against her, Senpai on the other hand will attempt to murder Ayano if she pushes him too far.
  • Gay Option: Senpai is male by default, but he can be made a female, turning Senpai (and the entire game) into this. If the option is given to play as a boy, then it will be this a second time around.
  • The Generic Guy: He's a walking nod to all the generic Nice Guy protagonists of harem anime and dating sims. It's to the point where his name is the Japanese equivalent of John Smith.
  • Hello, [Insert Name Here]: So far, it's planned that while he's only referred to as "Senpai"†  in dialogue, the player would be able to pick a name for him that would appear in Student Info and social media.
  • Heroic BSoD: Suffers a nasty one if he discovers his childhood friend Osana's dead body.
    Senpai: Osana?! What's wrong?! Are you hurt?! Osana!! Oh my god!! Osana!! Answer me!! Wake up, please, wake up!! Don't do this! Oh, god!! This can't be happening!! NO!! ...no... ...hello...police? ...I'm...a student at Akademi...my friend is...dead...I'm not sure what happened...please...send someone...anyone... [sobbing]
  • Hero of Another Story: With the tropes listed here and the fact that he slowly starts amassing a harem, he'd serve as a fine protagonist of a harem anime or Dating Sim if he was the lead character. Unfortunately for him, he's in this game.
  • Hero with Bad Publicity: If too many girls die or go missing immediately after meeting Senpai, rumors may spread that he is a serial killer.
  • Human Sacrifice: He is this for several very powerful people. Namely the SAIKOU Corporation, but the Headmaster and others as well. All these people know that Ayano is targeting him and that her family has been targeting men for generations. And yet they are perfectly okay with letting her do so unchallenged, saying that she "serves a purpose". What that purpose is has yet to be revealed, but it still all come down to the fact that they're essentially feeding this poor boy to a monster so that they can reap some benefit from a lifetime of suffering.
  • Inherently Attractive Profession: When Muja Kina substitutes the school's nurse for a week, Senpai gets sick and visits her cabinet a lot. According to YandereDev, Senpai might have a fetish for nurses.
  • Insane Troll Logic: Senpai will come to...interesting conclusions regarding all women, not just the rivals, if they are all eliminated in a certain fashion. This is especially strange if senpai happens to be female herself.
    • If the rivals are made to disappear without a trace, Senpai will jump to the conclusion that all girls are delinquents, who routinely skip school. Ayano herself can fall into this category if the player missed too many classes.
    • If the rivals are instead framed for murder, he will come to believe all women are bloodthirsty killers.
    • Lastly, if the rivals are Driven to Suicide, he will get the impression that all women are suicidally-depressed.
  • Lipstick Lesbian: If Ayato (or any of the Rule 63 versions for that matter) never gets implemented, then Taeko is this by default, since she's a Girly Girl who only has female Love Interests.
  • Love Interest: To Yan-chan. And about ninenote  other ladies… who need to be… dealt with.
  • Meaningful Name: Senpai's placeholder name, Taro Yamada, is about as generic a name as the default design for Senpai (being a rough Japanese equivalent to John Smith or John Doe).
  • Mr. Smith: His placeholder name, Taro Yamada, is a rough Japanese equivalent to John Smith or John Doe.
  • Multiple Endings: Senpai will develop different complexes depending on how Yan-chan eliminates the rivals. Some examples:
    • Majority of rivals commit suicide — Senpai develops a fear that all women are on the brink of suicide.
    • Majority of rivals framed for murder — Senpai develops a fear that all women are murderers.
    • Majority of rivals set up with another boy — Senpai worries that no girl will ever love him.
    • Majority of rivals expelled from school or have their interactions with Senpai sabotaged — Senpai develops a negative opinion of women.
    • Majority of rivals die in "accidents" — Senpai worries that he is cursed.
    • Discovers that Yan-chan is the cause of all his misery — Senpai attacks her.
  • Nice Guy: He seems to be a kind and all-around decent guy, which is what attracts so many girls to him.
  • No Name Given: He's simply known as "Senpai" by most people, although his actual name is Taro Yamada (the Japanese equivalent of John Smith). The Dev has said he would like for the player to be able to choose Senpai's name.
  • Not Good with People: Downplayed. He prefers nature, classical music, and a good book to spending time with other people. That said, while he's introverted, he's a Nice Guy who happens to become a Chick Magnet over the course of the game.
  • Oblivious to Love: He doesn't seem to realize that he's very desirable to his classmates.
  • Ordinary High-School Student: Is this for the most part.
  • Please Wake Up: In the second part of the January 2017 Osana Progress Report, as he witnesses Osana choking to death on poison, he'll say this to her.
    "Osana, answer me! Wake up! Please wake up! Don't do this!"
  • Purely Aesthetic Gender: While he's male by default, it will be possible to choose his gender in the final product.
  • The Quiet One: Senpai prefers solitude, and he's often seen sitting alone at lunch.
  • Roaring Rampage of Revenge: The developer has hinted that, at the end of the game, if you have pushed him too far and he finds out that Yan-chan is the source of all his misery, she's probably getting a knife to the face. If you kill his sister, he will attack you in retaliation.
  • Sanity Meter: He also has one that steadily decreases as he witnesses bad things happening around him. If his sanity is at rock-bottom by the end of the game... see Roaring Rampage of Revenge.
  • Sanity Slippage: YandereDev plans to have this happen to him if his sister and/or his Childhood Friend are killed.
  • Screw This, I'm Outta Here:
    • If he sees a body, he'll leave campus to alert the cops.
    • If you sabotage Osana's Thursday event by disabling her alarm clock so she sleeps through their designated meeting time, Senpai will eventually lose his patience and head home.
  • Senpai/Kōhai: Senpai is Ayano's senpai because he's one year above her. He's also Osana's (as she and Ayano are in the same class).
  • Significant Double Casting: If male, he shares a voice actor with Yan-chan's father. Why is it significant? 
  • Turn the Other Cheek: He's a pretty forgiving dude to his love interests (with the exception of Yan-chan). That said, his patience has its limits and he will not accept a confession from a rival whose social events have all been sabotaged.
  • Unlucky Everydude: Despite being an Ordinary High-School Student, he attracts the attention of a Yandere and is going to be put through the worst experience of his life.
  • Unwitting Instigator of Doom: Him meeting Ayano, and Ayano falling for him, is the reason for (almost) everything evil that happens in the story.
  • What the Hell, Hero?: He says this trope verbatim to Osana when he hears the doctored voice recording that Yandere-chan makes to frame her for badmouthing him.
  • You Monster!: Says this verbatim to Yan-chan in at least one of the bad endings.

    Info-chan 

Info-chan

https://static.tvtropes.org/pmwiki/pub/images/info_chan_artwork.png

"You're a client and I'm a provider. That's all we need to know about each other."

Voiced by: Cayla M Martin

Ayano's ally in "winning" Senpai's affections. Yan-chan can take pictures of her classmates and send them to Info-chan for, well, info. Yan-chan can also send her panty shots or plant listening bugs in order to earn various "favors" from her. She's is 18 years old, belongs to her own little club of one, and is exempt from most school rules due to blackmailing the Headmaster.


  • Ambiguously Bi: She was originally intended to be the final rival for Senpai's affection, but in her official art, she's looking at a Panty Shot photo while blushing. This implies that her reasons for requesting them aren't just so she can sell them to other people. However, YandereDev stated that she's possibly asexual and/or has no time for relationships.
  • Best Served Cold: Among the segment of the fandom that believes she is the daughter of the Journalist, there is speculation that her motivation for working with Yandere-chan is to expose her, and probably her mother, for their crimes.
  • Blackmail: According to Yan-chan, she has a history of blackmailing girls. For a price, you can have her do her thing to your rivals. A Headmaster tape released with the Delinquents update in April 2018 reveals that she actually blackmailed the headmaster himself into giving her ownership of the room she now works out of, the equipment she needs for work, and ample privacy to do her thing.
  • The Chessmaster: She is constantly gathering information, developing professional connections (at least a few of them with very shady people), and maneuvering people towards unknown ends.
  • Crazy-Prepared: She has at least one CCTV camera installed, right outside the Info Club room (wherein she has barricaded herself).
  • Curtains Match the Window: Red eyes and red hair to match.
  • The Dragon: She's Yan-chan's main ally in her quest for love.
  • Even Evil Has Standards: Though she accepts panty shots in exchange for favors, she doesn't accept any panty shots from corpses. However, this might be for pragmatic reasons, as those would be very incriminating — not to mention that (hopefully) no one would buy them.
  • Evil Duo: With Ayano. Yan-chan will send Info-chan upskirt photos, while Info-chan introduces the rivals to her and also provides basic information about anyone whose face Yan-chan photographs. If Yan-chan sends Info-chan enough upskirts, then Info-chan will do favors, such as give out blackmail or send a student home.
  • Eviler than Thou: She's even worse than Yan-chan, and that's saying something.
  • Evil Redhead: Absolutely.
    • In the first (now outdated) intro, she was the one who pushed Yan-chan to take action against Osana Najimi, outright telling her to kill.
    • In the second intro, she's fully aware of Ayano's nature (Yan-chan already wants Osana dead), and also seems to hold some sort of grudge against Osana and has no qualms about sending Osana to her death. She will probably be similarly callous about other rivals.
    • In-game, she responds to photos of your murder victims with nothing more than "good work, but I don't need photos like this".
  • Final Boss: Played straight early in development but later averted. She's the mythical Second Yandere, and concept art exists of her and Yan-chan having a rooftop knife fight during a thunderstorm. However, that idea was eventually scrapped.
  • Freudian Excuse: Although future developments could eventually refute it, some things in the game imply that she's the daughter of the Journalist.
  • Four Eyes, Zero Soul: Wears glasses which are visible even in the gloom of her hideout and is just as sociopathic, if not more so, than Yan-chan herself.
  • Friend to Psychos: She's a "friend" to Yan-chan, although they're less actual friends and more simply allies who are mutually exploiting each other. The second intro of the game seems to imply that Info-chan has something against Osana Najimi.
  • Get Out!: If the player manages to glitch or mod their way into the Info Club, the game resets the week. Before that, though, you can hear Info-chan's response to Yan-chan suddenly appearing in the room, which is less than positive.
  • Greater-Scope Villain: It's very likely that she has her fingers in many other pies. If nothing else, she's definitely the Greater-Scope Villain to Yan-chan's Big Bad.
  • Hated by All: Her reputation, at least as "Info-chan", is permanently set at -999. note  Everyone at school knows what she does. This is a big reason why she keeps her true identity a secret.
  • He Knows About Timed Hits: Offers tutorials to Ayano regarding many game mechanics such as reputation, sanity, murder, etc.
  • Hidden Agenda Villain:
    • Unlike Ayano, Info-chan's reasons for wanting Osana to die are completely unknown at this moment. All she says about it is that she'd "be happy if something bad happened to Osana-chan", and that Yan-chan is the right person to give Osana "what she deserves".
    • If it really is true that she's the Journalist's daughter, then her motives for working with the daughter of the woman who ruined her father's life are even more mysterious.
  • Hypocrite: Her interests state that she has a positive feeling about the concept of justice, ignoring the fact that she's a criminal and is willing to help out a potential Serial Killer/Spree Killer/mass murderer.
  • In-Series Nickname: She acknowledges her nickname when introducing herself to Yan-chan.
  • Karma Houdini: YandereDev doesn't want her to be killable, and her being the second Yandere was scrapped. Unless she ends up being a Bonus Boss, it's likely she'll get away with everything scot free.
  • Knowledge Broker: She's able to identify any student you send her a picture of along with various other useful information on them.
  • Meaningful Name: She helps the player learn more about the other characters. When a picture of a character is taken, she'll tell Yan-chan everything she knows about them.
  • No Love for the Wicked: YandereDev has stated that she's possibly asexual and/or has no time for relationships. And she's probably more immoral than Ayano. Ayano can be a horrible murderous monster, but she can just as easily be a school cupid. Info-chan will always be a blackmailer, black-market dealer, enabler of criminal activity, and information broker who deals in panty shots, and implies that she wants something horrible to happen to Osana, an innocent girl.
  • An Offer You Can't Refuse: Part of her reputation is that when she asks for a favor, you do it... or else.
  • Oh, Crap!:
    • Not a reaction you'd expect from a girl as cool-headed as Info-chan, but, in Mission Mode, if you manage to snap multiple photos of Nemesis, Info-chan's reactions slowly go from confused to this.
      "Strange, I have no profile for this student."
      "...wait. I think I know who she is."
      "You are in danger. Avoid her."
      "Do not engage."
      "I repeat: Do. Not. Engage."
    • If, by some miraculous chance, you manage to get away with taking a panty shot of the Nemesis, Info-chan would not recognize her panties. The July 2017 update changed her response to this, and, like her above quotes, it is not a reaction you want someone like Info-chan to have;
      "Wait...I recognize those panties! That person is extremely dangerous! Avoid her at all costs!"
  • Only Known by Their Nickname: Everyone calls her "Info-chan" because no one knows what her real name is. The dev has implied this is intentional on her part – she goes out of her way to avoid anyone associating her true identity with "Info-chan", to the point of leading a double life. He also stated her real name will probably never be revealed, since it's not important.
  • Psychotic Smirk: Her default expression.
  • Punctuated! For! Emphasis!: If you send her enough photos of an undisguised Nemesis, she will be quite succinct in telling you to stay the hell away from her.
    "I repeat: Do. Not. Engage."
  • Red Eyes, Take Warning: She's red-eyed, and she's the handler who's manipulating a (potential) Serial Killer. Heck, she was originally a second Yandere.
  • The Rival: The original plan for the game, as stated by the dev, was for Info-chan to make her move on Senpai during the final week and for you to have a Battle in the Rain with her. This idea has since been scrapped.
  • Sailor Fuku: Just like every other girl in school.
  • Scary Shiny Glasses: Red half-frames.
  • Shrouded in Myth: According to YandereDev and the demo's intro, she's an urban legend that few believe.
  • The Sociopath: She has a disturbing lack of empathy and a willingness to dabble in extortion, blackmail, and murder. In Mission Mode, she works with a hitman, and the Info-chan from the main timeline "wouldn't be opposed to it".
  • Stalker Without A Crush: The way she gets her information; either she (through planted bugs) or her "connections" spy on whoever she wants spied on. Yan-chan herself can be one such "connection" if you so choose.
  • The Unseen: Sort of. She does attend school, but she spends all of her time in the (locked) Info Club room and cannot be interacted with directly, although you can peek in to see her at work. Her profile picture is in silhouette (except for her glasses and hair). Attempting to access her profile leads to a glitched out screen and a (recorded!) message from her telling you not to bother.
  • Voice with an Internet Connection: While she'll be attending school like all other students and will communicate with Yan-chan, you'll never actually encounter her in-game in order to avoid the dilemma of being able to kill her.note 


The 10 Rivals

These are the ten ladies who challenge Ayano's love for Senpai. All of them like him along with one other so that you can play matchmaker and set them up with someone else if you wish.

At the beginning of the term, Senpai will only be liked by fairly average girls who are easy to deal with. Over the next ten weeks, the rivals become tougher to defeat. The rivals will not be in school before their week begins, so you can't get rid of them early. If you finish off a rival early, you will get the option to skip to the next week.

    As a Whole 
  • Always Female: All ten rivals are female, even if Senpai is also female.
  • Anguished Declaration of Love: All of the rivals will do this if you don't stop them. note 
  • The Bad Guy Wins: From Yandere-chan's perspective, any of them successfully confessing their love to Senpai is this.
  • Contractual Boss Immunity:
    • Info-chan has (or will have) an option where you can call in a favor to get a student sent home by faking devastating family news. However, the Rivals will be immune to it, to prevent Yan-chan from sabotaging their confession that easily.
    • Rivals are almost never actually alone, unlike most other students, to prevent you from easily ambushing them.
  • Contrasting Sequel Antagonist: Every one of them (if you include "development rival" Kokona as one of the rivals) contrasts a previous rival.
    • While Kokona didn't know Senpai very well, Osana Najimi is his childhood friend.
    • Unlike the abrasive Osana, Amai Odayaka is a very gentle and sweet girl.
    • Whereas Amai is very kindhearted, Kizana Sunobu is selfish and self-centered.
    • In contrast to Kizana, who loves being in the spotlight and has a big ego, Oka Ruto is a very shy and insecure girl.
    • Unlike the shy and quiet Oka, Asu Rito is energetic, exuberant and very extroverted.
    • In addition to being the first adult rival, Muja Kina contrasts Asu through their respective competence levels. Asu is a good enough athlete to be seriously considered as a future Olympic gold medal winner, while Muja is so inept at her job that she makes her patients worse off.
    • Mida Rana is an intelligent woman, unlike the dimwitted Muja. Also, while Mida's a very innocent woman whose apparent innuendos are unintentional, Mida is perverted to the point of being a sexual predator and her use of innuendo is completely intended.
    • Unlike Mida, who preys on teenage boys, Osoro Shidesu actually took some teenage boys in need of protection under her wing.
    • Not only is Hanako Yamada the first rival who's not romantically interested in Senpai, she contrasts Osoro by being far more girly and openly affectionate than her.
    • Finally, Megami Saikou contrasts Hanako by being far above her in social class, as well as being a longstanding and major part of the school's establishment unlike Senpai's New Transfer Student younger sister.
  • Curtains Match the Window: The vast majority of the rivals have the same color hair and eyes, regardless of how much or little sense it makes. Amai and Asu are the major exceptions.
  • Dark Secret: Each of the rivals will have one that can be used against them.
  • Driven to Suicide: If you destroy their reputation enough.note 
  • Flowers of Romance: This Reddit post by YandereDev details how each rival would react to being given a flower. Osana would call it stupid, but put it in her hair while denying that she likes it; Amai would treasure it; Kizana would throw it away and get angry at the giver for not realizing that her favorite flowers are roses; Oka would be surprised (and happy), Asu would thank the giver and offer to go with them for a run sometime; Muja would bump into the giver, apologize, and only notice the flower on the ground later; Mida would giggle slyly and offer to have "a word" with the giver after class; Osoro would tell the giver to keep the flower; Hanako would thank the giver and mention that it reminds her of a time she picked flowers with her brother; Megami would say that she appreciates the flower.
  • Gender Flip: For April Fool's Day 2017, the introduction video was re-posted featuring bishified male versions of them… only this time, it wasn't Senpai they were after, but Ayano herself.
  • Has a Type: The Matchmaking elimination method revolves around figuring out each rival's type and molding a student who has a crush on them into fitting those criteria.
  • Hero of Another Story: In a less-insane Dating Sim, they would be the members of the harem each trying to win protagonist Senpai's heart. You could honestly make a game based on them romancing Senpai. Unfortunately for them, they're in this game.
  • Iconic Item: YandereDev had mentioned (and the Rival Introduction video later confirmed) that each rival would be recognizable by a pair of unique stockings.note 
  • Love Interest: To Senpai.note  All the rivals will also have a second crush that you can pair them with.
  • Kill the Cutie: Some of the rivals are meant to be likeable and/or cute (such as Hanako and Oka Ruto), but all will be killable. That's one of the punishments you can mete out for their getting in between Yan-chan and her Senpai.
    YandereDev: Several of the rivals are supposed to be likable characters who don't deserve to die. I want the player to feel shame/guilt.
  • Murder the Hypotenuse: You don't have to kill them, but you can, and many gameplay features involve the various ways you can murder them.
  • Pair the Spares: Aside from murder, you can peacefully remove them by setting them up with someone other than Senpai.
  • Permanently Missable Content: Maybe? Four of your rivals are club presidents. Normally, killing or kidnapping a club president results in their club being disbanded and any perks Yan-chan could gain from that club disappearing. However, YandereDev has given conflicting information about whether killing or kidnapping these club presidents during their "Rival" weeks would also result in the club shutting down for good. note 
    • As mentioned on the main page, killing or kidnapping a student who is set to be a Rival's secondary suitor renders Matchmaking impossible for the week. Same story if you kill a student who would be involved in a Rival's Befriend/Betrayal (e.g. Musume). This is intentional, and is your consequence of playing the game as a murder-happy nutcase.
  • Punny Name: All but one of the rivals (Hanako) have either this or a Meaningful Name.
  • Removing the Rival: You'll have to get rid of them one way or another if you want to keep your Senpai.
  • The Rival: Each one is Yan-chan's rival for Senpai's affections. Even more so with Oka and Megami, since they’re both implied to be aware of Yandere-Chan’s true nature.
  • Sailor Fuku: Every student rival – that is, all of them except Muja Kina (substitute nurse), Mida Rana (substitute teacher), and Megami Saikou (who wears the white Student Council blazer) – wears the standard Akademi uniform. Some, like Osoro and Oka, may wear a jacket over it.
  • Single Woman Seeks Good Man: They all went after the Nice Guy. Of course, they're also planned to have another crush that Yan-chan can pair them off with to get them out of her way without killing them.
  • Video Game Caring Potential: You can eliminate them peacefully by befriending them (and then asking them to leave Senpai alone) or matchmaking them with a different boy...
  • Video Game Cruelty Potential: ...or you can murder them, get them arrested, torture them into insanity, get them expelled (or in the case of Mida Rana or Muja Kina, fired/arrested for unprofessional conduct and violating age of consent laws), or drive them to suicide by getting the entire school to bully them. Whatever works.
  • You Bastard!: Many of the rivals are designed to be extremely likeable girls with endearing personalities. The developer stated that he wants players to feel guilty about killing them.

    Osana Najimi

"Did you oversleep again? Ugh, you always keep me waiting! D-don't get the wrong idea! I-it's not like I like you or anything… dummy!"

Voiced by: Brittany Lauda

The very first of Yan-chan's rivals. She is Senpai's Tsundere childhood friend and secretly harbors feelings for him. Because she believes in the Myth of the Cherry Tree, she plans to tell him of her feelings on Friday under that tree to make sure he'll accept her. Osana serves as a tutorial of sorts for the player and is the easiest rival to defeat. But beware; Osana herself has no combat skills, but she is almost always accompanied by her best friend, The Indestructible Rival, Raibaru Fumetsu.


  • Because You Were Nice to Me: If Ayano befriends Osana, by sneaking into Osana's stalker's house to get Osana's cat back so the stalker can't use the cat as leverage to prevent Osana calling the police, Osana will pay Ayano back by agreeing to stay away from Senpai as Ayano requests, which will non-violently eliminate Osana as a rival.
  • Blatant Lies: She will often do something nice for Senpai, and then feed him some excuse about how it was just convenient for her or something like that.
  • Butt-Monkey: As the first true rival to be revealed, she tends to be on the receiving end of a lot of abuse.
    • Several non-gameplay-related videos feature her being brutally killed. For example:
      • "I Want My Senpai Back"
      • "It's Beginning to Look a Lot Like Murder"
      • "Raising the Strength Stat" doesn't show her being killed per se, but Yan-chan does grab her by the pigtails and hammer-toss her into the stratosphere.
    • As progress on her AI and routines continued into 2017, she took on this role in-game as well.
    • And now that the "official demo" has been released as of August 31st, 2020, Osana is officially in the game and thus players can eliminate her (by pacifistic or violent means) as they please.
  • Celebrity Resemblance: This is why the stalker is harassing Osana; Osana happens to resemble an anime character the stalker is in love with named Miyuki, so the stalker wants to have Osana to himself because it's the closest to having Miyuki in the real world.
  • Childhood Friends: With Senpai (and his sister Hanako).
  • Childhood Friend Romance: If you don't butt in, she'll become Senpai's girlfriend.
  • Clingy Jealous Girl: In this video (made by the game's voice actors), Osana is willing to have a (relatively) civilized rap battle with Ayano, until Ayano taunts her with the idea she's going to bang Senpai. Osana responds by attacking her.
  • Closet Geek: Her dark secret is that she writes Self-Insert Fic pairing herself with boys from her favorite anime.
  • Curtains Match the Windows: More or less for her ginger hair.
  • Deadly Rotary Fan: Easily the goriest way to kill her. By unscrewing a fan grate on the rooftop HVAC unit and luring her up to the roof, Yan-chan can feed one of her very long pigtails into the fan, which will proceed to suck her in, tearing off her head and spraying blood everywhere.
  • Died in Your Arms Tonight: One means of eliminating Osana leads to her eating a lethally poisoned lunch and dying in Senpai's arms. YandereDev states that being forced to watch as his childhood friend dies in his arms while he can do nothing but helplessly beg her to stay with him will cause more damage to Senpai's sanity than any other means of eliminating her.
  • Et Tu, Brute?: Ayano can optionally befriend Osana after rescuing her cat from the stalker, but Ayano can also optionally drug Osana's tea so Osana can be tied to a chair and eliminated.
  • Fiery Redhead: She has orange hair to go with her Tsundere personality.
  • First Girl Wins: If she gets to confess to Senpai, since she's the rival of the first week.
  • Freudian Excuse: Her Dark Secret has been hinted at, and now that the "official demo" has been released as of August 31st, 2020, players can discover what it is. A stalker is harassing her, to the point where Osana threatens to call the police, but the stalker has kidnapped her pet cat and is threatening to kill it if Osana calls the police. The stalker in question is in love with an anime character named Miyuki, and wants Osana to dress up as her and be his girlfriend because Osana superficially resembles her.
  • Friendship Trinket: After Osana and Raibaru became best friends, they became so close that they started wearing matching hair accessories.
  • Girlish Pigtails: Wears her hair in pigtails, as a nod to the typical Tsundere image. They were originally short and plump, but were later designed as more long and slender.
  • Has a Type: If you decide to use the Matchmaking elimination method, you can eavesdrop on Osana admitting to Raibaru that she developed feelings for Senpai gradually, but Senpai isn't normally her "type". Osana is normally attracted to tan skin, glasses, a ponytail, and piercings, and the man also has to be intelligent. If you tell these details to Kyuji Konagawa, he will change his appearance accordingly, and then you can matchmake them.
  • Heterosexual Life-Partners: She is this with Raibaru, the previous president of the Martial Arts Club. This factors into her week, as Raibaru never leaves her side and attempting to kill either her or Osana while they are together is the equivalent of a suicide. That said, their friendship can help Ayano to gather information about her rival's interests and secrets.
  • Hypocrite: Will come across as one to Senpai if you sabotage her Thursday event by setting off her alarm clock and making her oversleep and lose the date. Senpai will run out of patience and leave, after which he says that Osana claims he's the one who's always late.
  • I Can Explain: Every time you sabotage an interaction with Senpai, YandereDev states that Osana calls Senpai after school and explains the circumstances, which is why they are on good terms the next day. This is why you must sabotage multiple events, once might be explainable, but multiple times is a cause of concern.
  • Important Haircut: If she's still at school during week 2, she'll have cut her hair short. According to an earlier conversation with Senpai, she promised herself not to cut her hair until "a certain idiot stops being stupid and realizes how I feel about him."
  • Insult Backfire: In an unofficial, but official-voice-actor-made, rap battle, she insults Ayano by calling her a freak, only for Ayano to respond by stating she is a freak in the sheets.
    "I don't think he'll complain when he gets me in the sheets~"
  • Jerkass to One: So far, it seems like she's usually nice to just about everybody... except Senpai. As she's a Tsundere.
  • Jerk with a Heart of Gold: She seems to be a decent person otherwise. As an example, she acts rather friendly to Ayano during her Friendship Task. There are also quite a few occasions where she's genuinely nice to Senpai.
  • Kindhearted Cat Lover: She has a cat phone charm and a pet cat, and she's generally a Nice Girl outside her Tsundere moments. Saving her cat is the key to befriending her.
  • Living Emotional Crutch: Downplayed. She is childhood friends with Senpai, and if she dies, it'll take a large chunk out of his hidden Sanity stat. (Second only to killing Hanako.)
  • Meaningful Name: Her full name is Japanese for "childhood friend", and has this sort of relationship with Senpai.
  • My Sister Is Off-Limits: According to YandereDev here, Osana is the only aversion to this that Hanako will allow. Since they're childhood friends, Osana is the one person she is willing to "give" her big brother to.
  • Nice Girl: to anybody other than Senpai or her stalker.
  • Not What It Looks Like: The social sabotage route involves making her look like she is a Lethal Chef who is careless with other people's property, takes lewd photos, doesn't keep her appointments, and talks shit about Senpai behind his back. Naturally, this doesn't endear her to Senpai one bit.
  • No Sympathy: If Yan-chan eliminates Osana nonlethally, but kills Hanako, YandereDev has said that Osana will make no attempt to comfort her grieving childhood friend. This is especially jarring since Osana is also friends with Hanako, and Hanako herself would be upset if Osana were the one to die, which goes way beyond her tsundere behavior and straight into cold-hearted territory.
  • Off with Her Head!: One of her unique elimination methods results in this. Yan-chan removes the protective grate covering the school's rooftop heat/air unit, then grabs one of Osana's long pigtails and feeds it into the moving fan – Osana gets sucked into the unit and violently decapitated before it explodes.
  • Ordinary High-School Student: She doesn't appear too abnormal, aside from being Akademi's only ginger.
  • Patient Childhood Love Interest: She's had feelings for Senpai since they were kids. It's even in her Punny Name, since it basically means "childhood friend" in Japanese.
  • Punny Name: Her name loosely translates in English to "childhood friend".
  • Recorded Spliced Conversation: One of the events that can be sabotaged involves Ayano recording a conversation between Osana and Musume, and editing the audio to make it seem like Osana is disgusted by Senpai.
  • Self-Insert Fic: If you pay Info-chan for Osana’s dark secret, it’s revealed that she writes self-insert fanfiction where she romances the boys in her favorite anime.
  • Small Role, Big Impact: She may only be the first rival, but the way you deal with her has one of the biggest impacts on Senpai's sanity in the game, due to their past together.
  • Starter Villain: She's the first "villain" to go up against our "hero", Ayano-chan. The developer has said she functions as a tutorial of sorts… though there is also likely to be an actual tutorial to teach new players basic mechanics before Osana's week officially begins. note 
  • Supreme Chef: Her Monday event has Senpai enjoy a bento she makes for him. A little emetic poison will fix that quite nicely.
  • Symbol Motif Clothing: Her stockings, hair scrunchies, and phone case are pink with white polka-dots.
  • Tears of Joy: If Senpai accepts her confession on Friday, she will cry out of happiness.
  • Technicolor Eyes: Orange ones, to match her hair.
  • Through His Stomach: The progress report video on her shows her trying to win over Senpai by preparing him a boxed lunch, which Yan-chan can sabotage with emetic medicine.
  • Tsundere: This is her character type, first glimpsed in the original opening cutscene:
    "Don't get the wrong idea! It's not like I want to walk to school with you! I only walk with you because you'd probably get lost without my help! You're hopeless!"
  • Tsurime Eyes: Has upturned eyes because she's a tsundere.
  • Unlucky Childhood Friend: If only because she unintentionally ran afoul of Yan-chan.
  • Warm-Up Boss: The developer confirmed that Osana is this, as her strength is weak, she has no club or posse, and she's much easier to befriend or frame than future rivals. However, she'll still have a routine that always keeps her near Senpai or other students, unless you put in the work to get her alone. And now that the "official demo" has been released as of August 31st, 2020, Osana's friend Raibaru is always following Osana around, so Raibaru will need to be dealt with first in order to get Osana alone.

"Senpai, you're just in time! I baked cookies, would you like some? ...Y-y'know, Senpai...I wouldn't mind cooking for you every day..."

Voiced by: Kimberley Anne Campbell

The caring president of the Cooking Club. She is an excellent chef-in-training who loves to see people enjoy the food she prepared. A sweet, gentle girl who will bond with Senpai quickly. During her week, she operates a bake sale in the school courtyard- conveniently placed so that the students who hang out there (and Senpai) will notice immediately if Yan-chan tries anything.


  • A Friend in Need: After Senpai is feeling sad and vulnerable, reeling over however you eliminated Osana in the previous week, Amai becomes Senpai's friend just when he really needs one, which also kick-starts Amai's own romantic feelings towards him.
  • Because You Were Nice to Me: Inverted; if you don't eliminate Amai, then a romance can happen because she was nice to him.
  • Beware the Nice Ones: Possibly. In a video where YandereDev discusses the possibility of implementing an elimination method that involves driving the rival to murder and getting them arrested, he illustrates his point with an image of Amai covered in blood, carrying baskets full of organs, and holding a severed human head on a plate.
  • Big Ol' Eyebrows: While her current 3D character model lacks them due to technical limitations, her official design shown on the game's website is noteworthy for making her one of only two rivals in the entire game to have thick eyebrows (Osoro is the other). Itachi and Miyuji also have big eyebrows.
  • Boyish Short Hair: Inverted. Her hair is fairly short compared to most other rivals, probably so she doesn't have to tie it back when cooking. However, she's about as far from a tomboy as one can get.
  • The Chick: Is probably the kindest rival out of all of them.
  • Cool Big Sis: She's very cool, considering she's so sweet and caring.
  • Curtains Match the Window: Notable for being one of two rivals to avert it – Brown hair and green eyes.
  • Feminine Women Can Cook: Very girly-seeming and the president of the Cooking Club.
  • Nice Girl: She's been consistently described as a gentle, caring Cool Big Sis type; as her profile on the website notes, "nothing makes her happier than seeing people enjoy the food that she has prepared." Also, she's nice enough to offer to be Senpai's friend simply because he was feeling sad and vulnerable and really needed one, which is what can kick-start a romance if you fail to eliminate her.
  • Punny Name: "Amai (甘い)" means "sweet (taste)" in Japanese; odayaka means "calm" or "gentle".
  • Relationship Upgrade: It is remarked that Amai and Senpai become close because she is friendly and Senpai needs a friend. She is hoping for more.
  • Supreme Chef: She kinda has to be, since she's the president of the Cooking Club. The character page confirms that Amai's culinary skills are far beyond those of a normal high schooler.
  • Through His Stomach: She will make Senpai food as she gets close to him.
  • Tomboy and Girly Girl: She's the Girly Girl to Asu's Tomboy.
  • Wake-Up Call Boss: Since Amai is not a "demo" rival like Osana, it's likely that eliminating her will be significantly more difficult than the first week.

"It's only natural that I'd get the lead role in the play! I deserve it more than anyone else. Senpai~, I'm going to be Juliet. Would you be my Romeo?"

Voiced by: Katelyn Barr

The self-centered president of the Drama Club. She harbors three desires – to be the most popular girl in school, to be the greatest actor to ever live, and to get Senpai. That last one means Yan-chan must deal with her.


  • Alpha Bitch: Has elements of this. Her short-term goal is to become the most popular girl in school, and she's described as haughty, arrogant, and rude. In the video addressing Kokona's and Kizana's similar appearances, she is shown copying Kokona's hairstyle, then demanding that Ayano tell Kokona to change it because it's now "hers".
  • Big-Breast Pride: Kizana has the largest chest of any student rival in the game (slightly bigger than Megami's) – yet another thing she has in common with Kokona. Unlike Kokona, Kizana has never been shown to regret her top-heavy proportions.
  • Composite Character: Potentially. Her current design strongly resembles Kokona Haruka, one of the first NPCs to be introduced into the game and also the debug builds' test rival.note  It is possible that some of Kokona's backstory could be reused for Kizana. While the developer once considered making the two characters one and the same, blowback from fans (who pointed out the two characters' nearly opposite personalities) forced him to consider more creative options. As of now, nothing is settled.
  • Drama Club: She's its leader.
  • Fatal Method Acting: In-Universe. It's been hinted that each of the rivals will have unique murder methods that can be used only on them, and hers would involve dying on-stage.
  • Flower Motifs: Red roses, as a symbol of both the romance she's hoping for and her desire to be adored as a performer. She wears two roses in her hair and one on her black choker, her stockings are patterned with images of roses and leaves, and her introductory video has her being showered with roses while spotlighted on-stage.
  • Irony: The play she's trying to romance Senpai with is Romeo and Juliet, of all things. This play is one of Shakespeare's tragedies, a drama about two kids who just fell in love and, in less than a week (three days to be exact), it ends abruptly with their self-inflicted deaths. Depending on how things go – that is, how the player deals with her – either Kizana will be killed in less than a week (abruptly ending her attempt to woo Senpai), or she'll confess her love to Senpai… at which point Yan-chan might very well kill them both and herself (if the "Promo Concept" is any indication).
  • It's All About Me: She's very fond of herself. One proposed solution for the whole Kokona/Kizana problem is to have her rip off Kokona's hairstyle, then browbeat Yan-chan into forcing Kokona to change her hair so she can have her own unique hair. Real mature.
  • Jerkass: Kizana is arrogant, selfish, and egotistical. It has been stated that she dislikes anyone who is more popular than her, would want more money to be given to her club just because another club got more money, and, if given a flower, would throw a fit and reject the gift while calling the giver stupid for not realizing that she likes roses, telling them to leave and get her a better gift. A proposed plotline is to have her copy Kokona's hairstyle and then accuse Kokona of copying her and demand that she change it so she (Kizana) can look original. In this plotline, she would tell Ayano to make herself useful and demand that Kokona change it for Kizana because confronting Kokona herself is beneath her.
  • Know-Nothing Know-It-All: Though she must have some talent to become the president of the Drama Club, she's still described as "arrogant".
  • Large Ham: Kizana clearly has a flair for the dramatic, as shown in her currently available dialogue. She also speaks a lot with her hands during her proposed task, as seen in the video focusing on her and Kokona. It makes sense really; she is a stage actress, after all.
  • Lovable Alpha Bitch: Newer videos from YanDev have had him toying with the idea of making Kizana this, rather than a straight-up Alpha Bitch. Sassy, commanding, and charismatic, but still likable and ultimately a nice person, at least in public.
  • Meaningful Name: "Kizana" means "snobbish", while "Sunobu" is Engrish for "snob". The dev describes her as "someone who thinks of herself as royalty".
  • Narcissist: She has many characteristics of one. Her defining trait is her pride. She thinks of herself as far more important and knowledgeable than she really is, and she hates it whenever anyone makes her feel inferior. She pays no mind to those she deems unworthy of her attention and has a grudge against Megami for being more popular. While she is fond of Senpai, it would not be surprising if she still loves herself more. The possibility that she'll push him to be an actor if she wins his affections implies such.
  • Pride: Has a lot of confidence in herself.
  • Proud Beauty: According to hypothetical dialogue, Kizana wouldn't feel too bad about masks being banned because "a mask would only rob the school of the privilege of being able to see my stunning good looks."
  • Romance on the Set: In-universe, apparently this is part of her tactic of romancing Senpai. She's trying to nudge him into the Drama Club. The school's play happens to be Romeo and Juliet. She feels she's the best to play Juliet. And well, what better way to get your crush to notice you than having to act out a romance together? She doesn't seem to consider how the play turns out for the titular characters, however.
  • Small Name, Big Ego: She's very fond of herself, and while she is a talented actress, she doesn't appear to have any other skills. This may change once we see more of her, though.
  • To Be a Master: According to her character profile on the official website, Kizana's goal is "to be the most famous actress who has ever lived".
  • The Tragic Rose: Potentially. She has a rose motif reflecting her desire for love, and this can result if you take her out via murder or bullying by proxy.
  • Ungrateful Bastard: A reddit post from YandereDev about the reaction each rival might have if given a flower has Kizana berating the giver and calling them stupid for not realizing that she likes roses and rejecting the gift, telling them to get out and come back with a better gift. Even Osoro's reaction is much less mean.

"We're about to summon a demon... Would you like to join us...? ...I can't stop thinking about that boy... I think he cast a hex on me..."

Voiced by: Caitlin Myers "Mom0ki"

The weird president of the Occult Club. She has a strong belief in the supernatural, and wants to dedicate her life to proving such creatures exist. After falling in love with Senpai in a short period of time, she believes there's something supernatural about him. Uniquely amongst the rivals, she appears in the debug builds†  as an interactable NPC to provide functionality for her club. Her routine will be different when she is a rival. Her NPC persona is "Coward". She is in class 3-2.


  • Ambiguously Human: Like Yan-Chan, there just seems to be something off about her, for a lack of a better term. Plus, it’s also implied that like Yan-Chan, she also possesses supernatural powers, as judging by her claim to see the darkness in people’s auras and(correctly) seeing whether or not Yan-Chan has killed people before.
  • Arch-Enemy: Not in the game itself, as they are never shown to interact, but in works by their shared voice actress, мσм0кι, Oka Ruto and Midori Gurin are always at odds with each other, especially in this video, with Oka using demon powers against "Magical Girl Pretty Midori".
    • With Yan-Chan too. In terms of development time, she’s the rival that’s been around the longest, making her feud with Yan-chan even more pronounced that the other rivals. Also, in the game, it’s implied that she and Megami are both aware of Yan-Chan’s true nature.
  • Aura Vision: She claims to have this, and if she witnesses Yan-chan committing a murder, she'll say she can't join the occult club because her aura is too dark and will attract evil spirits.
  • Breakout Character: She may very well be the most popular of all the rivals. This is due in large part to her strange, cute, and quirky personality… and the fact that she was present in the debug builds (while most other rivals stayed under wraps for nearly a year) so fans had a chance to get to know her. YandereDev openly said he considers her the cutest of the rivals, although that was only part of the reason he introduced her early.note  As such, she appears very often in other works outside of the game itself, especially those made by her voice actress.
    • In fact, a thread on the game's subreddit asked players who they were going to kill or spare once the game was finished. Almost all of the commenters vowed to spare Oka.
    • Kjech has also alluded to this. When he drew this sketch of Oka, he referred to her as "Everyone's favorite" and admitted he feels tremendous pressure when drawing her due to not wanting to upset her legions of fans. Of course, said fans loved the sketch.
  • Chuunibyou: She has a severe case.
  • Creepy Child: "Child" is pushing it (as a senior, she's 18 or close to it), but still… YandereDev describes her as "creepy" and "spooky". Her idea of a fun club activity is attempting to summon a demon.
  • The Cuckoolander Was Right: Turns out you can summon demons…
  • Curtains Match the Window: Dark blue hair and eyes. An updated character model made her eyes more purple, but it's still close enough to count.
  • Early-Bird Cameo: In a meta sense. Oka's not the first rival (she's actually the fourth), but she was added to the debug builds as a NPC nearly a year before most other rivals were unveiled, for a variety of reasons – while Kokona was the elimination guinea pig, Oka has been used to test several technical character model things.note  Her presence in the game led to her club being one of the first to have full functionality.
  • Eerie Pale-Skinned Brunette: She has very dark blue hair, and she will eventually have a pale skin tone.
  • Everyone Has Standards: Like the rest of the Club Presidents, she'll kick you out if she finds out you killed someone. If she does so in person, she'll even note the irony of getting kicked out of an Occult Club for being too spooky.
  • Exhausted Eye Bags: Always has these.
  • Expy: YandereDev describes her as a mixture of Tharja from Fire Emblem: Awakening, Hex Maniac from Pokémon X and Y, and Tomoko from Watamote.
  • Goth: YandereDev says he was inspired to make her when someone suggested a goth girl rival. She definitely counts in appearance and tastes.
  • I Just Want to Have Friends: Oka's dialogue makes it clear that she's very lonely and insecure, and she's surprised and elated if Yan-chan joins her club.
    "…y-you…actually…want to join?" [yes] "…this is wonderful news… perhaps the world isn't such a dark and lonely place after all…"
    • This carries over to if Yan-chan decides to leave the club. Oka's obviously devastated by it.
      "y-you're not…going to leave us…are you?" [yes] "…well…that's to be expected… I mean, who would want to be in this club anyway…"
    • Mechanic aside, her dialogue, if Yan-chan tries to rejoin, suggests that Oka isn't getting over it anytime soon.
      "...um... you already left this club once before... I... don't want to let you back in... you might just leave again... and it hurts when people leave... I don't want to be hurt again..."
  • The Insomniac: YandereDev confirmed that the shadows around her eyes are from her staying up late researching paranormal things.
  • I Reject Your Reality: Oka dismisses any evidence that the Basu sisters aren't supernatural. The fact that Inkyu can survive in sunlight leads her to rationalize that Inkyu's a special kind of vampire.
  • Irony: This girl is a walking, talking ball of it.
    • She rambles about Aura Vision to someone who actually has it (that'd be Yan-chan).
    • Upon inquiry, Oka says the Occult Club's goal is to "develop a resistance to horrific and terrifying things... or succumb to them", and its activity consists of trying to summon a demon.
    • She's obsessed with and stalks the Basu sisters, convinced that they are supernatural beings, but has no idea that a real supernatural being (or five) inhabits the club room where she would otherwise spend all of her time.
    • If Yan-chan leaves the Occult Club of her own accord, Oka will grimly muse aloud about why anyone would ever want to join her club anyway… in front of her five club-mates.
    • If Oka herself witnesses Ayano murder someone, she'll either refuse membership or kick Yan-chan out, saying Yan-chan's aura is too dark and will attract evil spirits. Once again, the club's activity is attempting to summon a demon.
    • If Yan-chan is in the Occult Club and one of the other members sees her commit murder, Oka will kick her out on the basis that Yan-chan is too scary. Oka herself lampshades the situation.
      "um… I'm sorry… you can't be a member of this club anymore… you're too scary… huh, that's ironic… being kicked out of a club about scary things… for being too scary…"
  • Loners Are Freaks: Is described by the dev as an outcast. She's also pretty freaky. Note however that, as an NPC, she does not have the game's "Loner" personality type, but rather the "Coward" one.
  • Messy Hair: She essentially has perpetual bed hair.
  • Nightmare Fetishist: Comes with the territory of being the President of the Occult Club. She also spends most of her evenings watching horror movies, reading Creepypasta, and researching paranormal things. Student Info even tells us she doesn't appear to have much interest in anything else.
  • One-Winged Angel: In the Yanderetale minigame, she gains The Horror's Not!Vectors.
  • Opposites Attract: She, a self-proclaimed seeker of the supernatural, is attracted to the milquetoast Senpai.
  • Peek-a-Bangs: Her first hairstyle was like this, as part of her unsettling appearance.
  • Permanently Missable Content: In the debug builds, killing or kidnapping her results in her club being shut down. May or may not be the case if you take her out during her Rival week.
  • Punny Name: "Oka Ruto" sounds like an Engrish pronunciation of "occult".
  • Put on a Bus: In the August 18, 2018 build, she was removed from the game so that she could be retooled into a proper rival.
  • Shout-Out: Does one in-game. Her description of the Occult Club contains this little gem:
    "…witches, ghosts, vampires, demons, aliens, psychics, and time travelers are all welcome here."
  • Shrinking Violet: She walks with her head down, her hands clasped in front of her, and her shoulders pulled up. Her quiet, halting voice only drives in the point further.
  • Speech Impediment: Prior to her having voiced dialogue, the developer typed out a sample line from her that suggested she had a stutter. In the game itself, she does not speak with a stutter, but her speech is very halting and deliberate, like how someone who subconsciously compensates for a stutter would talk.
  • Stalker Without A Crush: She stalks the Basu sisters in an attempt to prove their supernatural nature.
  • Symbol Motif Clothing: She has dark purple gloves and stockings absolutely covered in a spider web design. It fits with such a spooky girl. Based off this picture that has been released it will probably be part of her final design.
  • Unkempt Beauty: One old picture of her depicts her quite nicely, and she's pretty good looking despite her messy hair and baggy eyes.
  • What Is This Thing You Call "Love"?: Oka's dialogue in the Rival Intro Video suggest she is not actually aware that her feelings for Senpai are "romantic love", so she thinks Senpai put a hex on her.

"Nobody in the sports club ever turns down a challenge! Come on, let's get started right away! Senpai… would you like to go on a run together? Y'know, just the two of us?"

Voiced by: Dawn M. Bennett

The athletic president of the Sports Club. She's the top student athlete in the region, and her classmates predict she'll be winning Olympic gold medals in a few years. A cheerful and friendly girl, she finds it very easy to make friends, and her nature is what attracts Senpai to her.


  • Action Girl: She is the president of the Sports Team, so she must be.
  • Action Girlfriend: Will be this with Senpai if you don't stop it.
  • Ambiguously Brown: She is quite tan in her artwork, although her in-game model has lighter skin due to technical limitations.
  • The Big Girl: Is the most active of the rivals.
  • Boyish Short Hair: As president of the Sports Club, this is practical.
  • Foil: To Itachi Zametora. While Asu is positive and cheery, Itachi is gruff and unfriendly towards everyone.
  • Genki Girl: Her character profile describes her as "perpetually cheerful and energetic".
  • Lesbian Jock: Bisexual Jock in her case. She's the president of the sports club and the top athletic student in the region, and she also swings both ways, as she will pursue a relationship with either a male or female Senpai.
  • Light-Haired Swimmer: She has dark skin and blonde hair due to how much time she spends outside and in the pool.
  • Lovable Jock: Is your rival, but seems alright.
  • Modesty Shorts: She wears black and yellow shorts under her skirt.
  • Passionate Sports Girl: Must be to be the leader of the Sports Club and Swim Team Captain.
  • Punny Name: Like Oka's name seen above, Asu Rito's name is Engrish for "Athlete".
  • The Smurfette Principle: She is the only female member of the Sports Club.
  • Tomboy: We're assuming this because she's so sporty. Also that hair.
  • Tomboy and Girly Girl: The president of the Cooking Club, Amai Odayaka, is the Girly Girl to her Tomboy.
  • Unknown Relative: The profile information of the Gym Teacher suggests that she may have one.

Voiced by: Dawn M. Bennett

The substitute school nurse and a rival to Senpai's affections. Her characterization has been described as pure and innocent, if a little blind to certain implications. She loves taking care of people, but her klutzy nature often causes problems…


  • Combat Medic: She will have a "Heroic" persona, meaning that she will respond to murder by attempting to disarm Yan-chan. Just how strong she is hasn't been revealed yet, but since the teachers are no pushovers, she likely won't be either.
    • That said, YandereDev has waffled regarding this concept, and stated that he might make her the only faculty member who is incapable of self defense. He has also stated that one of the Headmaster's tapes will explain why she was employed despite this.
  • Crazy-Prepared: In the game, she moves around certain items so that the player won't know where to get them.
  • Curtains Match the Window: Pink hair and pink eyes.
  • Cute Clumsy Girl: She's even spilling ethyl alcohol in her character art, and in the Rival introduction video, the in-game visual it freezes on is of her tripping while carrying a tray of syringes.
  • The Ditz: She's described as rather less than intelligent. It's been stated that she tends to make things worse for her patients due to her incompetence, has no defense training or combat experience, is a clumsy oaf, and, if she were given pepper spray, she would accidentally spray herself.
  • Early-Bird Cameo: She was in the debug builds from mid-2015 until August 2017 (when she was replaced by the regular nurse), albeit as a model without any programming. Her status as an official rival was confirmed by her red aura.
  • Ephebophile: She does show interest in a high school senior. It's been implied by YandereDev that Senpai may come on to her due to having a nurse fetish.
  • Florence Nightingale Effect: YandereDev says Senpai will become ill at the start of her week, and will visit the nurse's office once a day. Combined with Senpai's thing for nurses, this illustrates why you need to eliminate her.
  • Foil: To Mida Rana, the substitute teacher, whose schtick is intentional innuendo, unlike Muja's own tendency to make Innocent Innuendo. There's also the fact that Mida is smart and has had extensive self defense training, while Muja is an idiot who can't defend herself.
  • Hartman Hips: Is also quite gifted in another certain area.
  • Hospital Hottie: She's a nurse and has a highly sexualized figure.
  • Impossible Hourglass Figure: Even in the context of this game, she has one.
  • Innocent Innuendo: YandereDev says that her schtick is "unintentional innuendo".
  • The Load: She's stupid, clumsy, makes things worse for her patients, and can't even defend herself from a teenage girl.
  • May–December Romance: Will get one with Senpai, though she's so innocent that she might not actively search for it. And, again, she likely isn't that much older than him.
  • Meaningful Name: Her name, Muja Kina, is derived from mujaki na, which is Japanese for "innocent".
  • Pink Is Erotic: Muja is a rival because Senpai has a nurse fetish and her outfit is one of the most risque designs in the game. Her nurse uniform consists of pink and white, with her cleavage and thighs being shown.
  • Put on a Bus: Being a substitute nurse, she will leave the school when her week is over, regardless of how she is eliminated. However, YandereDev has stated that there might be a reason for her to stay at Akademi despite the fact that the official nurse has returned; namely, she might stay as the nurse's intern/trainee.
  • Rose-Haired Sweetie: She's so innocent that she's unaware of how things can sound to teenage boys. Naturally, she has pink hair.
  • School Nurse: It's in her description!

"I can teach all sorts of things. Would you like me to be your… private tutor?"

Voiced by: Marissa Lenti

The horny substitute teacher. She loves being the center of attention, especially from teenage boys. Seducing schoolboys is her hobby, and no man has been able to resist her charms.


  • Asshole Victim:
    • If you decide to kill her. She regularly seduces her own students (who may or may not be of legal age) for sport. However pleasant she may appear to be, she's still in gross violation of occupational ethics at best and a sex offender at worst.
    • In fact in the same subreddit poll mentioned above under Oka Ruto, whenever the commenter wasn't going for a multi-kill or full kill everyone scenario, in which case she is usually included as a victim, she is the rival most commonly singled out as being the one rival they would specifically kill off, even in a mostly pacifist run, and she is rarely ever spared, so apparently even the fanbase agrees that, in this case, it would be good thing to Kick the Son of a Bitch.
  • Badass Teacher: Like the other teachers, she will have extensive self-defense training, so she'll be just as capable.
  • Depraved Bisexual: Considering the fact that she's a horny ephebophile who takes joy in seducing male students, but would happily do the same to a female senpai, she's this.
  • Determinator: It's said that once she has her sights on a boy, she will not let up. Of course, she's yet to meet Ayano-chan.
  • Ephebophile: The thing she enjoys most about her job is that it gives her access to teenage boys she can seduce.
  • Even Evil Has Standards: She spends her time seducing her male students (which is a crime, even if they are of legal age, due to her being in a position of power). That said, she will be horrified by murder, just like the other rivals.
    • YandereDev has also stated that she wouldn't make any lewd/inappropriate remarks regarding a teen pregnancy due to how serious of an issue it is and would offer any advice she could to someone going through a personal crisis.
  • Expy: YandereDev says she was inspired half by Noriko Kashiwagi, and half by Mitsuka Yoshimine.
  • Foil: To Muja Kina, the substitute nurse whose shtick is Innocent Innuendo, while Mida's innuendo is completely intentional.
  • Hartman Hips: Like Muja, and unlike her, she's fine with using them to her advantage.
  • Hate Sink: She's a shameless Ephebophile who constantly persues her own students and has no problem abusing her authority in order to do so. Needless to say, there are few players who can stomach sparing her.
  • Hot Teacher: She's sexy, and she certainly knows it.
  • May–December Romance: Clearly wants one with Senpai, and is said to have had some similar relationships with previous students.
  • Mrs. Robinson: An adult woman who's a serial seducer of teenage boys.
  • Ms. Fanservice: As part of her lewd nature, she has a more overtly sexual design.
    • One of the Headmaster's tape will explain why she was hired to work at Akademi High despite the way she dresses.
  • Proud Beauty: She's well-aware of the effect she has on teenage boys, and enjoys the attention.
  • Punny Name: Her name is a play on midara na, which means "lewd".
  • Put on a Bus: Like the School Nurse, she will leave the school at the end of her week. She's a substitute teacher, after all. However, YandereDev has stated that there might be a reason for her to stay at Akademi despite the fact that the teacher she was substituting for has returned; namely, she may be hired as Kocho Shuyona's secretary.
  • Really Gets Around: Seducing schoolboys is her hobby.
  • Sexophone: Her leitmotif, heard during the "Rival Introduction" video.
  • Shadow Archetype: To Genka, Akademi's counselor. Both are school faculty members who dress in dark clothing, have shapely figures, show a lot of cleavage, and play an adversarial role to Yan-chan. They also happen to share a voice actress. However, while Genka is consistently professional in her dealings with students, Mida has numerous sexual conquests among the teenage boys she's taught, and shows no signs of stopping anytime soon.
  • Shameless Fanservice Girl: YandereDev has confirmed that if she noticed Ayano taking a upskirt shot of her, she would actually be flattered. She'll still turn you in to Genka if you're caught taking panty shots of other students, but only for your lack of subtlety than you doing it at all.
  • Significant Double Casting: Shares a voice actress with Genka Kunahito, which is significant for the reasons detailed above.
  • Teacher/Student Romance:
    • What's she's hoping for. Will happen if you don't step in.
    • Possibly if you do, as well. If matchmaking with her works the same as with all the other rivals, you'll be able to set her up with a different student than Senpai.
  • The Worf Effect: Considering the fact that she would be one of the few rivals capable of fighting back, and she's one of the teachers, and comes right before Osoro's week, with Osoro being noted to be the hardest of the rivals to (physically) take down, she would be this if you were to try and eliminate them both via murder.

"Girls like you really get on my nerves. Get lost! ...That boy... he's the only one who..."

Voiced by: Alexis Silvera

The leader of Akademi's gang of delinquents, she is the strongest character in the game. She spends the first several weeks of the game suspended from school due to some very serious infraction. Beyond that, little is known, due in part to everyone else being terrified of her.


  • Action Girl: She's the strongest, toughest, most competent fighter in the game, including Budo and the teachers. The only student who matches her strength is Raibaru.
  • Amazonian Beauty: Some official artwork portrays her as extremely attractive, and she is pretty muscular. Just look at the size of her legs.
  • Authority Equals Asskicking: She's the delinquents' boss, and YanDev has stated that she'll be the most difficult rival to (physically) take down, even harder than Megami.
  • Badass Armfold: Her official character art features her standing with her arms crossed.
  • Battle Trophy: Her Coat Cape acts as one, since she took it from a student from a rival school who tried to beat her up. After she beat him up instead, she took his coat as proof of her victory, and wears it every day.
  • Because You Were Nice to Me: Considering it's been stated that her love for Senpai will bloom from a friendship, as well as her saying Senpai was "the only one who..." before being cut off in the rival video, it's implied this is why she falls for him.
  • Charles Atlas Superpower: Osoro is almost ludicrously strong for a teenage delinquent. She is stated to be the strongest student as well as the strongest rival, putting her above Budo Masuta, Muja Kina, and Mida Rana. Budo Masuta is the president of the martial arts club, and Muja Kina and Mida Rana are adult women employed at a school where extensive self defense training is a requirement for faculty. YandereDev has stated that she could even give a mindslave trouble, despite them being capable of killing teachers.
  • Coat Cape: She wears a coat this way, which is fitting for a delinquent girl. She took it from a member of a group of thugs who tried to attack her one day.
  • Contralto of Danger: Her voice is one of the deepest in the game. As for the "danger" part, she's said to be tougher than Budo.
  • Cool Big Sis: She is this to the other delinquents; they idolize her absolutely and form their core identities around her. Their self-worth comes from her approval.
  • Covered with Scars: A promo image shows her with scars on her back and arms, and her in-game model shows she has a large cross-shaped scar on her face.
  • Dark Action Girl: She's the leader of a group of delinquents, the toughest student in the school, and was suspended for unknown but serious reasons. In the delinquent backstory trailer, it is revealed that she brutally took down a large group of students from another school when they attacked her at the entrance to Akademi High.
  • Delinquent Hair: Her hair is bleached blonde and poorly maintained.
  • The Dreaded: Most of the school avoids her out of fear due to her history of violent behavior.
  • Felony Misdemeanor: In the delinquent backstory, Genka blames the Delinquents' behavior on her and plans to use any excuse she can get to get rid of her for as long as possible in order to reform them. This is the most likely explanation for her suspension for the first seven weeks of the game.
  • Foil: To Musume. Both are blond haired female leaders of cliques comprised of not particularly nice people (the Bullies and the Delinquents, respectively). However, Musume and the Bullies are two-faced bitches with good publicity who keep their true natures hidden, while Osoro and the Delinquents are feared throughout the school. In addition, Osoro has a softer side to her, and the Delinquents tend to keep to themselves and only cause trouble if provoked, while Musume is a Hate Sink with no redeeming qualities, and the Bullies actively harass other students.
  • Hidden Depths: This is pretty much a given, since she's set to end up in a relationship with Senpai – on the surface her polar opposite – if you don't stop her. What those depths are remain to be seen, as she is at first glance a hotheaded uber-delinquent with a history of violent behavior. Her interests at least reveal that she's a fan of light music.
  • Japanese Delinquents: The core premise of her characterization, really.
  • Jerk with a Heart of Gold: The Dev has made it a point to mention that while she's a delinquent, she's not evil; and that if she catches Yan-chan in the act of murder, she will attack her, just like anyone with a "hero" persona. Further, she will form a bond with Senpai, and the fact that she's attracted to such a Nice Guy at all means something. Not to mention, Senpai won't ever accept you if he catches you doing something evil, or if you have an exceedingly low reputation… but he will accept Osoro if you don't intervene. There must be some good in her. Indeed, the backstory of the other Delinquents reveals that Osoro took them in and befriended them when they were being bullied to the point of contemplating suicide.
  • Meaningful Name: Her name comes from osoroshii, meaning "terrible", in reference to her fearsome reputation. "Desu", the other part of her name, suggests her Hidden Depths. Here's Why 
  • Missing Mom: According to YandereDev, her mother is dead.
  • Modesty Shorts: She wears black shorts under her skirt.
  • A Mother to Her Men: The delinquents all practically worship her, and follow her example. Before they became delinquents, they were seen following her around like ducklings. It's through her influence that they became delinquents in the first place, since she was the first person who presented them with a way they could stop being the targets of bullying.
  • Noble Demon: She is the leader of the delinquents and she has been suspended multiple times. However, there is clearly a good side to her. The backstory of the Delinquents reveals that she took the other delinquents in and befriended them when they were being bullied to the point of contemplating suicide.
  • Not So Above It All: As tough and tomboyish as she is, she still blushes in the Rival Introduction video.
  • Odd Friendship: She's the type of person that Senpai normally avoids, but will strike up a friendship with him when she becomes the rival.
  • One-Woman Army: The Delinquent Backstory video reveals she managed to single-handedly take down a group of students from another school, and took her iconic Coat Cape from one of them as a Battle Trophy.
  • Pet the Dog: She befriended Umeji Kizuguchi, Hayanari Tsumeato, Gaku Hikitsuri, Hokuto Furukizu, and Dairoku Surikizu when they were being bullied to the point of contemplating suicide.
  • Pitbull Dates Puppy: She's a tough Dark Action Girl who is interested in dating an introverted Nice Guy.
  • Riddle for the Ages:
    • The cause of the x shaped scar on her left cheek.
  • Sarashi: A piece of concept art (that did not show her face) reveals this is how she ties her boobs down.
  • The Smurfette Principle: Following the April 2018 build, all of the other Delinquents are boys.
  • Toxic Friend Influence: A sympathetic example. She's the one that taught the other delinquents to talk back to teachers, show up late, and behave rudely and aggressively towards other students. They all idolize her so much that they do it without question. However, she befriended them and took them under her wing in their time of need — before joining her, they were being bullied so badly, they were seriously considering suicide. So while she encourages their bad behavior, it comes from a place of genuine caring.
  • Ungrateful Bastard: Downplayed. In the Reddit post displaying each rival's possible reaction to being given a flower, Osoro's is to just tell the person who offered it to her to keep it. Considering that she's the leader of a group of delinquents, however, this seems rather tame considering the response that she could have given. If nothing else, her response seems perfectly polite when compared to Kizana's.
  • We Cannot Go On Without You: If she dies, her underlings will give up their delinquent ways.
  • World's Strongest Woman: Is the strongest student in the school, even stronger than the Martial Arts Club president, Budo Masuta.
    • The only one who matches her strength is the former president of the Martial Arts Club, Raibaru Fumetsu.
  • "X" Marks the Hero: She has an x shaped scar on her left cheek, and while she may be a delinquent, she did help out all the male Delinquents and stop them from committing suicide, becoming their friend when they needed one the most. She also would try her best to take Ayano down if she found out she was a murderer.

"Welcome home, big brother! How was your day? Tell me all about it! If you got a girlfriend...would you forget about me? That won't happen, will it?!"

Voiced by: Dawn M. Bennett

Senpai's cute little sister: a clingy, jealous, and emotionally dependent girl who demands her sibling's attention, so naturally she is a threat for Ayano even if not a typical rival. Rather than confess feelings of love at the cherry tree on Friday, she intends to take him there and demand he never take any girlfriends for her sake. Hanako is meant to resemble Senpai, and is likely to adopt any colour customization the player gives to him.


  • Adaptational Badass: In Mission Mode, the death of Taro leads to her becoming Nemesis-chan, who is basically an unstoppable force that's out to destroy you.
  • Big Brother Worship: She absolutely adores her big bro.
  • Break the Cutie: In one alternate timeline, Ayano killed Taro, which led to Hanako becoming Nemesis.
  • Cheerful Child: YandereDev has described her as a "happy anime girl", implying that she's going to be this. In one picture, she's making a similar pose to the Social Butterfly persona.
  • Clingy Jealous Girl: Non-romantic version. She doesn't like her brother romantically, she just wants him all to herself.
  • Crouching Moron, Hidden Badass: Normally, she's girly, cute, and described by the developer himself as a "happy anime girl". In one Alternate Timeline, she becomes so much of The Dreaded as Nemesis that even Info-chan knows to stay away.
  • The Cutie: Most likely the youngest and cutest of them all.
  • Early-Bird Cameo: As Nemesis.
  • Foil: To Kencho, Megami's younger brother, as he is antagonistic towards his older sister and wishes to replace her. Hanako is extremely clingy towards her older brother and doesn't want to share him with anyone else.
  • Girlish Pigtails: She has shoulder-length pigtails, with a heart-shaped hairpin for her bangs.
  • Girly Girl: The developer tells us that she's girly and cute.
  • Hidden Depths: Hanako is your typical adorable Little Sister Heroine who just absolutely wants to be as close to her big brother as much as possible. That said, the comic Retribution reveals that she would become Nemesis from Mission Mode if something happened to him.
  • The Ingenue: Originally planned to be this, but developed into a bit more of a brat.
  • Little Sister Heroine: Her presence in the game is a clear reference to this trope's prevalence in romance anime and dating sims. However, she's just clingy, not incestuous.
  • Living Emotional Crutch:
    • Downplayed. While they have a fairly average sibling relationship, Senpai has a hidden Sanity stat that can take a hit if rivals are killed off in similar ways. The death of his little sister will knock a massive chunk out of Senpai's sanity, and could result in him becoming suicidal, or even hunting down and killing the person responsible for it (that would be you).
    • The same is true in reverse: Mission Mode takes place in an alternate universe in which Ayano is a professional killer instead of a love-sick stalker, with her very first victim being one Taro Yamada. His death traumatizes Hanako so badly that she ends up becoming Nemesis, a merciless Serial-Killer Killer who is hell-bent on avenging her brother.
  • Mr. Smith: Her name is the rough Japanese equivalent to Jane Smith.
  • My Sister Is Off-Limits: Or in her case, brother. According to YandereDev here, Osana is the only aversion to this that Hanako will allow. Since they're childhood friends, Osana is the one person Hanako is willing to "give" her brother to.
  • New Transfer Student: She's so clingy that she transferred to Akademi near the end of the first trimester because she couldn't bear being away from her big brother for so long, which explains where she's been for the previous weeks.
  • The Not-Love Interest: She's not interested in actual romance or sex, but she does want to be Senpai's number one girl anyway.
  • Token Mini-Moe: She's Senpai's little sister after all. Downplayed because she's only two grades behind him, but she is the youngest rival.
  • Video Game Cruelty Punishment: You can kill Hanako just like all the other rivals, but YandereDev has made it abundantly clear that if you do that, it will result in a big hit to Senpai's sanity. However, if you murder her in front of Senpai, it will lead to your murder by Senpai himself!

"My top priority is to put a stop to anyone who poses a threat to this school! Senpai, I think someone may be stalking you, but don't worry, I'll keep you safe."

Voiced by: Amanda Lee

The wealthy, famous, beautiful, brilliant, strong, and otherwise perfect Student Council President, who is also the sole heir to the Saikou Corporationnote . She's in the game's debug builds, albeit only seen on a laptop in the Student Council room. She seems to have a vendetta against someone who may or may not be Yan-chan.


  • Abusive Parents: Like her aunt before her, she has been groomed since birth to take over Saikou Corp, regardless of her wishes and in defiance of her right to any sort of childhood.
  • The Ace: She's close to perfect. Of course, she could easily turn out to be a Broken Ace the more we see of her, since each rival is planned to have a Dark Secret. That said, quoth the character page: "Weakness: None". Fuck with her at your own peril.
  • Ambiguously Evil: Her venomous speech certainly sounds sinister, but considering the lack of context, it's not clear who she's talking to or how malevolent she is. And if it's true that the person she is talking to is Yandere-chan herself, she may very well be a Hero Antagonist. Still, some things about her make you wonder how good she really is.
  • Annoying Younger Sibling: According to YandereDev, her younger brother Kencho is the only person who can get under her skin and cause her to lose her temper.
  • Berserk Button: Killing any of the Student Council Members is this for her; she will respond by setting up extreme security measures such as cameras and metal detectors, which will permanently set School Atmosphere to its lowest possible setting. YandereDev describes killing a Student Council Member as a way of setting the game on hard mode.
  • Big, Screwed-Up Family: Is part of one; see the Saikou Corp folder on the "Other Characters" page for more details.
  • Boobs of Steel: To go along with her Sue-ish perfection, she has a noticeably larger than average chest – the second largest amongst the teenage rivals, in fact. And she's absurdly powerful in just about every way you can imagine.
  • Create Your Own Hero: Unlike the other rivals, whether or not Megami plans to confess to Senpai, let alone if she's even attracted to him, is rather ambiguous. She makes a Declaration of Protection to him because she and Oka both have suspicions of Yandere-Chan's true nature.
  • Declaration of Protection: Towards Senpai.
  • Deconstructed Character Archetype: It’s implied that she’s this to the Mary Sue archetype; she’s like this because her family keeps pressuring her into being perfect in every way, which caused her to become rather high-strung and standoffish. Her aunt was groomed in the same way many years ago.
  • Does Not Like Men: Rumors have spread about her not liking men, as all of the student council members are female, and the president must approve of someone before they're allowed to join the student council.
  • Even Evil Has Loved Ones: She genuinely cares about the fellow members of her Student Council. If one of them is killed, she will be furious and increase security restrictions on the school by adding security cameras and metal detectors.
  • Expy: She looks a lot like Satsuki Kiryuin with a slightly messier and pale hairstyle, and has the same kind of authoritarian personality, based off what we've seen so far and the word of YandereDev. Both characters are also the leaders of their respective school councils, and have a parent in charge of a major corporation. In fact, Megami's hair was originally jet-black like Satsuki's, but was later changed to silvery-blue to be less infringing; as of now, her concept bears some resemblance to B-ko Daitokuji
  • The Face: As the student body president, she serves as this for Akademi.
  • Face Framed in Shadow: When she initially speaks to Yan-chan through the laptop, her eyes are obscured by shadow. Following the redesign that gave her model silver hair, she is now entirely framed in shadow.
  • Fiction 500: Being heiress to the largest business conglomerate in Japan, she has enormous amounts of money.
  • Final Boss: She is the tenth and final rival Yan-chan must face. Fun Fact  Naturally, she will be the most difficult to eliminate.
  • Final Solution: Unlike her father, she says she has no tolerance for "vulgar creatures" and, if it were her decision, then "every last one of you would be exterminated." Who or what she's referring to isn't exactly clear.
  • Foil: A Lighter Shade of Black to Musume Ronshaku. Both are wealthy, popular girls who lead Girl Posses and wield great amounts of influence over the school. Megami is strict, professional, and leads the powerful Student Council, while Musume openly flouts school rules thanks to her father's wealth and is the leader of her Gang of Bullies. While Megami is a Hero Antagonist who wants to make the school a safer place, Musume is a Hate Sink whose only purpose is to make other students' lives miserable. Finally, while Megami cares about her fellow student council members and would become enraged if one of them were to be killed, Musume would backstab anyone, including her best friend, in a heartbeat.
  • Freudian Excuse: Her family has some... issues. The sheer volume of tangled, twisted threads of intrigue that surround the Saikou line is too much to explain here; see the Saikou Corp folder on the "Other Characters" page for details. Suffice to say that she has her reasons to be screwed up.
  • Grand Finale: In every sense of the word as the dev himself has said that Megami is "the end of everything". One can only wonder what's going to happen when she is eliminated.
  • Greater-Scope Paragon: Serves as a Hero Antagonist variant until week 10. She does not appear in person to deal with Ayano directly until then, but the rest of the student council is still around to enforce her will. Don't try killing them; that'll just prompt Megami to buck the rules and turn the school into a Police State, making your job much harder than it already was.
  • Hero Antagonist: More than any other rival. It's heavily implied that she knows that Yan-chan is a Stalker with a Crush who is Yandere for Senpai, and will do anything to stop her.
  • Hidden Depths:
    • While ostensibly a Parody Sue, her speech implies that she has a surprising amount of awareness about Yan-chan's true nature, and she herself exhibits unexpectedly dark traits.
    • She's noticeably upset about having to attend school via web chat, and resents her initial circumstances that prevent her from being a normal student.
    • As we’ve just said, she and Oka are both implied to know about Yan-Chan’s true nature.
    • When Megami is alone with Aoi, she behaves differently and is less formal than usual, implying some truth to the rumor that they're childhood friends.
  • I Just Want to Be Normal: She's physically absent for the first nine weeks of the game and attends via laptop, but she'd much rather attend school as a normal student.
  • Iron Lady: Authoritarian and strict, and with ruthless tendencies. Highlighting this, on the official website's character page, whereas most of the rivals have two character portraits, 'normal' and 'blushing', Megami is unique in having 'normal' and 'gentle'… and even her 'gentle' portrait still comes across as serious and stern.
  • Knight of Cerebus: Compared to practically every other character introduced to the game, she and everything known about her is portrayed completely seriously. No comedy, levity, or over-the-top exaggeration of anime clichés surround her character at all. The only remotely humorous thing about her is an Undertale Shout-Out in one of her lines and some intentional Sueishness, and even then, she still speaks some surprisingly threatening words in a grim tone. She seems to know exactly what's going on around her and is not going to take it sitting down.
  • Knight Templar: She's trying to protect the school from Yandere-chan and any other trouble makers. However, her methods are overzealous and borderline authoritarian.
  • Lack of Empathy: She would be offended rather than angry or sad if her younger brother Kencho was killed, and see his death as merely "a tremendous waste of time and money."
  • Marry for Love: According to YandereDev, she would like to marry someone she genuinely loves, if possible.
  • Meaningful Name: Megami means "goddess", while Saikou could be derived from "saikō", meaning something along the lines of "the best/the highest", or from saiko, meaning "talented". Both names are quite befitting of someone stated to be absolutely perfect and who stands to inherit the largest business conglomerate in Japan.
  • My Greatest Failure: Aoi's missing eye is rumored to be due to reasons related to Megami.
  • A Nazi by Any Other Name: As detailed under Final Solution, she has no tolerance for "vulgar creatures" and, if it were her decision, then "every last one of you would be exterminated."
  • The Not-Love Interest: Possibly, considering a Declaration of Protection can be completely platonic, and the pose she does when declaring it isn't referred to as a blush pose (as opposed to every other rival, even Senpai's own sister, having a blush pose). Regardless of whether or not she truly loves Senpai, she is still a threat once you take into account the implication that she knows Ayano's true nature and will do anything to stop her.
  • Ojou: She is described as the most beautiful and popular girl at Akademi Academy who is also the Student Council President and a wealthy heiress.
  • Parody Sue: The Dev himself once described her as a Mary Sue. Her profile on the official site describes her as the most popular, the most beautiful, the smartest, and the most talented girl in school. She's the heiress of a massive corporation that she will one day inherit, and is the Student Council President. On top of all this, she also somehow knows about Yan-chan's true nature and the dark secrets of Akademi High from the very beginning. Note, however, that unlike most Parody Sues, nothing about Megami is Played for Laughs. It’s also implied that she may somewhat of a deconstruction of the trope, since she’s heavily implied to be the way she is because she’s pressurized by her family into being perfect in every way, just like how her aunt was groomed to be the CEO in the last before she gave it all up.
  • Pet the Dog:
    • Megami is ridiculously harsh and strict, and is deeply suspicious of Ayano. However, she's not completely unreasonable; if you have a moderate or high reputation by the time Megami returns to school, Megami will seriously consider the possibility that she was wrong about her, and give Ayano the benefit of the doubt. (Depending on how you've been eliminating your rivals up until that point, it may even be deserved.)
    • According to YandereDev, if someone gave her a flower, she would appreciate the gesture.
  • Red Armband of Leadership: Natural for club leaders, but considering that she's an authoritarian with a rather fiery method of speaking, the confusion associated with this trope is even greater.
  • Screw the Rules, I'm Doing What's Right!: Megami is explicitly prohibited from taking any actions against Yandere-chan during the first 9 weeks of school, despite her suspicions of her. She'll keep to and follow these orders, but if Yandere-chan kills any of the members of the Student Council, whom she is very close to, Megami will turn the school into a borderline Police State with the express purpose of exposing Yandere-chan.
  • The Smart Guy: She is stated on her character profile to have genius-level intelligence.
  • Student Council President: She is one, though you can join the council to enact a plot against her.
  • To Be Lawful or Good: She'll keep her distance from the school and follow her orders to leave Yan-chan alone. If one of her friends on the Student Council dies, however, then the game increases in difficulty as she disobeys those orders.
  • Training from Hell: Went through it from an early age in order to inherit Saikou Corp.
  • Tranquil Fury: Her laptop speech is absolutely full of quiet, visceral disgust towards the subject of it.
  • Well-Intentioned Extremist: She knows Senpai has a stalker, and that there's someone dangerous at Akademi. She will do anything in her power to protect the school. This includes installing security cameras, hiring security guards, and instituting a zero-tolerance policy.
