School girls can't be murderers, I just want to go to school and learn things, like every other schoolgirl! Who has time for murdering people anyway? We have to study for exams! Murdering people would only waste precious time, especially for us schoolgirls! Are you insinuating that girls like me can be murderers? How terrible! | „ |

At least Genius, likely Extraordinary Genius
Despite her extreme mental illness, Ayano is an extremely cunning and strategic killer, throughout the game and through statements she's shown to be highly skilled in several different areas including academics, combat, manipulation, adaption, cooking/baking, sewing, video games, sports, acting, artistry, music, photography, and several different fields of science (forensics, physics, botany, toxicology, psychology, chemistry, sociology, biology, engineering, computer science, etc) all of these she displays exceptional proficiency in, being able to do things even real scientists would have trouble accomplishing in such a short amount of time, such as making stink bombs and bang snaps even without using any study points showing how even with her base knowledge she has a very deep understanding of chemistry, usage of tools and engineering. She's also able to utilize her skill in adaptation to change her personality to more easily blend in even while actively murdering people. Ayano attends Akademi, which is an extremely prestigious school being compared to Harvard or Yale in universe.
Knowledge/Learning
- Even without studying she intuitively knows how to craft stink bombs and bang snaps with stolen chemicals in the science lab
- Can study different classes and get one full level in just 2 days and immediately be able to reap the rewards of that knowledge
- For biology Ayano is immediately able to find utilize that knowledge to inject students with the correct amount of sedative to knock them out and how to inject them in the correct area. This also teaches her how to kill without spilling as much blood, the more she increases her biology knowledge the less mess she'll make.
- After just a the first level of chemistry she's able to learn how to create a non lethal poison, the next level allows her to make headache poison, the third lets her learn to make a sedative, the fourth lets her learn to make lethal poisons and the final one lets her learn to create smoke bombs. All of these are vastly above the level of a highschooler implying that she spends her time studying far more advanced topics than the school actually teaches.
- While studying language she is able to learn very quickly how to replicate someones vocabulary and writing style in order to forge notes and even suicide letters making murders look like suicides even after being investigated thoroughly by the police.
- Studying psychology lets her drive kidnapped students to madness much more efficiently as well as do better in social situations, give better matchmaking advice and lose sanity slower when killing
- Knows how to create weapons with random garbage and stolen items
- Knows how to grow poisonous plants without any need for prior learning
- At a very young age she was taught forensic countermeasures by her mother, most notably how to completely clean a crime scene. This scene also seems to imply that Ryoba (Ayano's mother) constantly taught her daughter about things like these which is what led to Ayano's deep knowledge in these matters, likely including how she knows how pick locks and craft complex items and traps.
- Ryoba was the protagonist of the 1980's mode where she was capable of getting away with at least 11 murders, and even successfully defend herself in court.
- This also showed that even as a child she was capable of understanding these lessons showing some impossible understanding of chemistry for a child her age.
- Can join the science club, which is comprised of genius students capable of inventing and creating things like humanoid robots and artificial intelligence. The fact that she's able to join and remain in the club by itself implies that Ayano is on a similar level, this is again supported by her taking part in some of the experiments.
- Despite the robot seemingly behaving normally, Ayano is able to mess with it's code and get it to kill for her and even self destruct. Two things that were almost certainly not implemented by Homu
Manipulation/Deception
- She has multiple ways to increase her reputation and good standing in school.
- Can drive fragile students to murder a rival by first decreasing the students reputation which causes bullying. Then they convince them that their bullying is caused by the rival, which culminates in the student killing them.
- Can slowly sabotage Taro and Osana's relationship which at the end of the game makes Taro reject her
- Knows how to break her victims minds to a point that they become completely subservient to her, even to the point of killing whoever she tells them to.
- Constantly deceives the entire school through various methods, this includes students, teachers and student council members one of which is shown and stated to be a genius herself.
- Despite Itachi not wanting or even seeing the value in having friends Ayano is still able to befriend him.
- Participating in the photography club meetings after a murder has been committed will cause the meeting the be about discussing culprits and showing off collected "evidence", and Ayano is able to participate in these discussions without being suspected.
Adaptability/Observation
Ayano's adaptability and observation is debatably her strongest point whether it be in combat, social situations, or academic pursuits, she displays a level of adaptability that is far beyond typical human limits. She rapidly improves and outpaces even those with extensive training, constantly reacts to the environment and adapts her personality and disposition to blend in seamlessly essentially making her the perfect social chameleon. All of which points to an extraordinary capacity for growth and processing speed, which at this level is would likely be impossible in real life.
- After gaining information on a student she's able to easily use that information to adapt to a students personality letting them fit into social situations much better.
- She spends her free time "researching and spending time learning about things and items that would trick people into thinking she is a normal girl" and "Ayano's "hobby" is trying to convince everyone around her that she is a normal girl with normal feelings. She buys manga, plays video games, and rides a bike to project the image of a regular school girl. However, she doesn't enjoy any of it"
- She learns to be a "normal girl" by eavesdropping at her school to learn what girls her age are doing or watching. Videos she watches includes what she learns from eavesdropping. If Ayano is asked about it, she can provide an answer and falsify her personality as a normal person who knows and enjoys the same things that other people her age know and enjoy. She also understands societal norms and expectations for a girl her age, understanding that she would be considered weird for not knowing certain trending topics. Which is why she watches movies or shows to keep up her façade, even though she doesn't care about watching them.
- She's able to switch her personality to mesh better with a person/student she's trying to manipulate
- Even as a little girl she was able to convincingly fake being "normal", she was also able to notice even at this young age that the people around her bullied her for being abnormal and so she again convincingly faked normalcy and the bullying went away.
- After studying her victims she can visualize their current location even if they can't actually see them, meaning she's so good at analyzing her victims behaviour that she can accurately guess their location based on behaviour alone, even doing so for multiple people at once.
- She's also able to visualize weapons and other helpful environmental factors
- Can build complex traps requiring the use of tripwires as well as predicting and/or manipulating the movement of the victim.
Strategy/Planning
All of these strategies are made up on the fly and usually with little to no prior prep time. Ayano is very opportunistic in her schemes and usually comes up with them after getting a small piece of information, such as hearing a rivals secret and somehow spinning that into a complex plan to befriend and betray them, or drive them to doing something drastic. Although info-chan does occasionally help by alerting Ayano of potentially important events she herself doesn't come up with the plans, thats all Ayano. One example of this is when she convinces another student to murder her rivals, info-chan casually references a students low self esteem and negative headspace and Ayano is able to use this information to manipulate that student into doing the "job" for her completely negating any risk to Ayano being discovered as a murderer.
Expulsion
Ayano has multiple different strategies to get her rivals expelled from school all non lethal and all ranging from simple things like framing for vandalism and theft to embezzlement and poisoning:
- Ayano poisons the pastries in the Home Ec room with a non-lethal poison. After that, she reports her to the guidance counsellor, and attends class.
- Ayano must wait until 8:15 AM, find a radio, use the radio to lure the gym teacher out of the faculty room, steal an answer sheet while she's distracted, and bring the answer sheet to Info-chan's room. After Info-chan makes a copy of the answer sheet, the player must pick up both copies, put the original back in the faculty room without getting caught, place the copied answer sheet in Osana's desk during lunch, report her to the guidance counselor, and attend class.
- She is able to obtain a pack of cigarettes before class. These can be found in the convenience store in Buraza Town, in the faculty room on Kaho Kanokogi's desk, or in Info-chan's "Drops" menu. Once the player has cigarettes, they must be placed in Osana's bag, which is at her desk. After that, the player needs to report her to the guidance counselor. The final step is to attend class as usual.
- She has far more schemes for getting rivals expelled, all of which display some level of skill in stealth and/or social skills and manipulation
Befriending
- Can befriend Osana by eavesdropping on a conversation and discovering that Osana has a stalker. She can then find the stalker break into his house without alerting the family, she then rescues the stolen cat which earns Osana's trust enough to get her to come to Ayano's house at this point she can either choose to tell Osana not to confess to Taro or she can drug her and keep her captive
Poisoning
- Can use stealth to get close to a rivals food allowing her to poison them without being spotted.
Kidnapping
- They can purchase headache poison and use stealth to put it in their food during lunch, this student will then go down to the infirmary which manipulates the nurse into unlocking the medicine cabinet letting Ayano steal the sedative without being seen.
- In order to successfully kidnap a student Ayano first needs to have at least 1 rank in biology and have a good relationship with a student, this lets her trick them into following her into a secluded location where she can safely sedate them and stuff them in a crate to be brought home after school usually intended for torturing them.
- Could kidnap a very popular girl who is also the daughter of a very wealthy man in a presumably very short amount of time
Matchmaking
- Ayano stalks her rival/utilizes Info-chan to get information on their likes and dislikes in a guy she will then find a suitable candidate in school, befriend the rival usually through some sort of underhanded/manipulative method to build enough to trust to tell her that someone wants to meet her. Ayano would then use a wireless headset to coach the suitor through the conversation and eventually she will get the two together avoiding any violence and successfully stopping her rival from confessing their love to Taro.
Drive to suicide
- Ayano is able to drive Osana to suicide by spreading gossip and discovering her "dark secret" and leak it on social media. This leads to ruthless bullying, and by -100 reputation Taro will now reject her confession. However Ayano is able to continue to lower her reputation and by -150 reputation she will commit suicide.
Drive to murder
- Ayano is extremely manipulative and knows just where her victims emotional weak points are, casually being able to manipulate a person who's described as "cheerful and friendly" into a brutal murder. While doing this she stays very close to the person she's tricked into committing the crime, actively helping set it up, talking them through the steps, preparing a weapon, etc. but at the last possible moment she will leave the crime scene. Even with the victims statement that Ayano was involved she was so careful and deliberate that the cops can't find a shred of forensic evidence to stick to her, no fingerprints on the bat (Besides Kokona's) due to the use of gloves, no witnesses seeing the two ever interacting due to Ayano always meeting in a secret place such as the roof, and apparently she even prepares a fake alibi which was stated to be "airtight".
- She was able to easily extract an embarrassing secret from Kokona despite them not being particularly close. She also quickly discovered who was extorting Kokona's father and found a way to utilize that information plan her framing job, in the span of just a few hours
At least Gifted, possibly Genius
Ayano is an extremely intelligent and creative fighter using several different methods to gain the upper hand on her opponents, although even without any tricks Ayano is a more than capable fighter usually able to fight those slightly stronger than her with pure skill alone, even those who are known for being aggressive and/or semi-skilled fighters (Such as the Delinquents and member of the martial arts club respectively)
- Even without investing any points into physical education Ayano is still able to fight off students who practice martial arts.
- After upgrading her strength she is now able to fight off teachers all of which have been extensively trained in hand to hand combat due to the principal's paranoia. This even includes a world famous Olympic athlete.
- If she joins the martial arts club she will automatically win every struggle against even the strongest teachers, even without upgrading her strength. Implying that she developed her fighting skills so fast that they quickly surpassed the extensive training the staff took. After joining students are now completely incapable of putting up a fight against her at all, including those with martial arts training showing that she quickly surpassed the students she sparred with too.
- Using surprise attacks she easily overwhelms people much stronger than her and will utilize distractions in order to accomplish this whether it be through the use of giggling or more complicated methods like bang snaps.
- Can use a variety of weapons all with wildly different weight, length, techniques, etc. and will use them all expertly
- Should be somewhat comparable to Osoro due to her being described as "the most dangerous girl in school, besides Ayano". Osoro was able to fight off a large group of boys all by herself even to the point of "maiming" the attackers. Accounts of the battle vary wildly from her being able to defeat 10 of them one at a time, to even fighting off 100 students all at once
- This is further supported by the fact that Ayano can defeat Itachi in hand to hand combat while it's stated that Itachi and Osoro would be the most even fight in Akademi.
- She's also capable of defeating Shiromi in a fight, Shiromi is stated to have a very high degree of skill in stealth and "ninjutsu", due to her father having been trained by a ninja and him passing that knowledge down to her
Weaknesses: Killing large amounts of people will drop her sanity, and the lower it gets the more frenzied and sadistic her kills get causing more mess. She will also be visibly insane meaning she's liable to be seen as suspicious due to her compulsive twitching, giggling and hallucinations.
