Weapons of Yandere Simulator as of the December 26th, 2018 Build

Weapons are tools used to commit homicide in Yandere Simulator.

When Ayano kills a person with any weapon, her uniform and weapon will be splattered with blood. Her sanity will decrease with each kill, although wearing the Tiny Thong Panties, belonging to the Occult Club, or increasing Ayano's Numbness level lowers the amount lost. To avoid getting arrested, the player must at least dispose of the uniform and the weapon using the incinerator. In future builds, different weapons may result in different amounts of blood, but this will be determined in the balance phase.[1] One way to balance the weapons would be to make non-suspicious weapons less lethal with longer killing animations.[2]


Weapons shown in the Challenges Menu.

Currently, there are seventeen weapons Ayano can use. The only available weapons that can currently be seen on the Challenges Menu are the knife, boxcutter, scissors, screwdriver, syringe, and katana.

Some weapons are considered non-suspicious and will not result in a reputation penalty if Ayano is seen carrying them. If Ayano is a member of a particular club, suspicious weapons associated with that club (such as the shovel as a member of the Gardening Club) will become non-suspicious.

Some weapons can be concealed, while others cannot. The player can check if a weapon is concealable by pressing the 1 key. As of the February 15th, 2016 Build, Ayano cannot use a non-concealable weapon when fighting a Heroic student, because the weapon is too unwieldy to use in close quarters and will result in automatically losing the struggle. Any non-concealable weapon can be hidden inside a cello case or a trash can.

If Ayano drops a weapon 10 meters away from its initial location, it will be considered as suspicious. Students that find the weapon on the ground will report it to their teacher. The teacher will then pick it up and place it inside of a box in the Faculty Room. If the weapon is bloody, the teacher will call the police, and any other students that see the bloody weapon will run to their classrooms.


As of the December 1st, 2015 Build, the game will track whose blood and whose fingerprints are on each weapon. If Ayano does not dispose of a bloody weapon, a teacher will find it and call the police. The police will try to trace the weapon back to Ayano. If she wears gloves, the police will not find her fingerprints on the weapon. As a result of this, she is able to frame other students by using weapons they have touched to commit murder. This method can be used after Kokona Haruka uses the knife in the Cooking Club. Since Kokona's fingerprints are the only ones on the knife, she will be arrested for the murder.

In earlier builds, Ayano would automatically dropped all weapons when the day ended. This would have been troublesome for a player who forgot to dispose of a weapon would leave it on the ground when Ayano left school. A teacher would then find it and call the police, and the police could immediately trace the weapon to Ayano. As of the January 2nd, 2015 Build, she will instead take the weapon home and dispose of it. If the police arrive at school, however, they will search the students and find the bloody weapon on Ayano's body, so she will still be arrested.


Main Article: Reputation

If students see Ayano carrying a dangerous weapon, they will see her as suspicious, thus damaging her reputation by ten points during high School Atmosphere, fifteen points during medium, and twenty points during low. Apologizing to a student will give her back some of the reputation lost. If a friend or a student that is being seduced by Ayano sees her with a weapon, her reputation will be affected by eight points. If she is in the Occult Club, it will take longer for students to notice her carrying a dangerous weapon.

If Senpai sees Ayano with a dangerous weapon, he'll become terrified of her, resulting in a game over. If a teacher sees Ayano with a dangerous weapon, she will be sent to the Counselor's Office. If a teacher sees her holding a dangerous weapon after a student has been murdered, she will assume Ayano killed the student and pin her down, apprehending her.

The scissors, box cutter, and screwdriver are classified as non-suspicious weapons. Ayano will not be considered "Visibly Armed" when carrying these weapons. In the final game, the only weapons available will be ones found in a school environment, unless she asks Info-chan to leave a weapon at the back of the school.

If Ayano holds a suspicious or bloody weapon near the delinquents, they will assume a menacing stance, ready to fight. They will lower their guard after she puts it away, and taunt her. If the player walks up to the delinquents multiple times a battle minigame will activate. Winning this minigame will result in being able to take the delinquents weapon and frame them for murder.[3]


Main Article: Sanity

In the final game, each weapon will have four killing animations, depending on sanity:[4][5]

  • Stealth kill: Performed from behind, with victim unaware. Quick, quiet and clean.

Low sanity kill animations will last longer than high sanity ones.[6]

  • High sanity kill: Efficient, but not as fast as a stealth kill. Produces some extra noise and blood. Will take two seconds.
  • Medium sanity kill: The victim struggles a little bit. The kill is sloppy and messy, thus taking more time. Will take four seconds.
  • Low sanity kill: Very prolonged killing animation that is unnecessarily brutal and sadistic. Victim screams and struggles. The player has the option to make Ayano continue to stab her victim indefinitely by mashing the "attack" button, causing a segment of the animation to loop until the player stops mashing. Will take six seconds.

More animations could show additional kill techniques that vary depending on weapon type and current sanity level.[7] Ideally, every weapon will eventually have a unique animation set. If this cannot happen, a less ideal scenario would be that each weapon type (short, stabbing, long, and bludgeoning) has its own animation set. At worst, all weapons will have the same animation.[8]

YandereDev will not implement any more animations into the game unless he has four sets of four animations for short sharp, long sharp, long blunt, and for the circular saw.[9]

  • As of the October 15th, 2017 Build, sound effects for picking up weapons have been added.
  • It is theoretically possible for a pencil to become a weapon, but YandereDev does not find it cool enough. He wants all weapons to be cool.[20]
  • If a small town is implemented, more weapons will be available.[21]
  • YandereDev has stated in an interview that the katana might be something that the headmaster confiscated and just never got rid of.[22]
    • As of the November 15th, 2016 Build, the katana is located in the Headmaster's office.
  • Ranged weapons will most likely not be in the game.[23]
  • Formerly, there were only three regular animations with a murder weapon: a sideways stab to the neck for the knife, scissors, box cutter, screwdriver, syringe, and ritual knife, a slam to the head for the katana, baseball bat, shovel, dumbbell, and a unique animation for the circular saw. There is also a stab in the head whenever Ayano wins a fight against a Heroic student and another when brainwashed, kidnapped victims finish a murder-suicide. All of the weapon animations have been replaced with the sanity-based attacks, except during fights against a Heroic student.
    • The animation used for the larger weapon, high sanity attack animations, (except the circular saw) is also used for when the old delinquents attack Ayano.
  • Ayano intends to kill when the player presses the "attack" button. There is no chance of knocking the victim unconscious or leaving them "Half-dead".[24]
  • There is a possibility that a sniper mini-game will be added purely for fun.[25]
  • It is very important to YandereDev that there's a cheat code or Easter Egg which unlocks a giant sci-fi energy scythe.[13]
  • In the future, it is possible that if students see a certain weapon lying around, they will give it to a teacher.[26]
  • YandereDev does not have the animations nor the models for choking someone with a rope or a chain yet. [27]
  • Cleaning bloody weapons was planned to be done with a sink. This, however, can currently be done with Drinking Fountains.[28]
  • YandereDev does not want to add guns to the game.[29][30]
