Weapons

Weapons are tools generally used to commit homicide in Yandere Simulator.

Weapons fall into any of the six categories: small stabbing weapon, large stabbing weapon, small bludgeoning weapon, large bludgeoning weapon, small strangulation weapons, and big strangulation weapons. There is also the Circular Saw, which is normally used for dismemberment but can also be used for murder.

Currently, there are 20+ weapons that the protagonist can use to kill a student. Each weapon has its own strengths and weaknesses, so the player has a lot of options when it comes to killing.

General

Suspiciousness

Some weapons are considered non-suspicious and will not result in a reputation penalty if the protagonist is seen carrying them. Other weapons, however, are considered generally suspicious, such as a fire extinguisher or a pipe wrench. Some weapons aren't considered suspicious if the protagonist is a member of a certain club.

If someone sees a non-suspicious weapon on the ground, 10 meters away from its initial location, they will pick up the item and bring it to its original place. Some suspicious weapons, such as a fire extinguisher, may also be picked up and brought to its place, but most of them will scare students, so if a student sees such weapon, they will call a teacher. If a teacher sees "scary" weapon, she will bring it to the Faculty room.

If Senpai sees the protagonist with a suspicious weapon, he will become terrified of her, resulting in the "Heartbroken" Game Over. If a terrified person sees the protagonist with a suspicious weapon, they will decide that the protagonist is a murderer. In other cases, people who spot the protagonist with a suspicious weapon will react according to their persona.

The reputation penalty for being spotted with a suspicious weapon is ten points during high School Atmosphere, fifteen points during medium School Atmosphere, and twenty points during low School Atmosphere. If a friend or a student that is affected by the protagonist's seduction level 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.

Bloody weapons

If a stabbing weapon is used to attack someone, it gets covered with blood. Blunt weapons will also get bloody if used in a frontal attack. Bloody weapons are always considered suspicious and scary, although Senpai may not see a small bloody weapon in the protagonist's hand. If a faculty member sees a bloody weapon, she will call the police.

If an uncovered bloody weapon is present when the protagonist attends classes (or is sent to a guidance counselor), a faculty member will find the weapon and call the police. The player may conceal the weapon, but this is only a temporary measure, because all concealed bloody weapons will be discovered at the end of the day. To prevent the weapon to be discovered, the player must wash the weapon in a sink or simply dispose of it.

Usually, a weapon that was disposed of will be replaced by the new one next day. However, as of the Big June Update of 2022, there are seven weapons that won't return once disposed of because they are one-of-a-kind. These unique weapons are the Katana, Magical Girl Wand, Fantasy Sword, Medieval Sword, Ritual Knife, Old Axe, and the Guitar.

If the police arrives at the school, they will find any bloody weapon and check fingerprints on all of them. If the protagonist touches any of those weapons with bare hands, her fingerprints will be found. However, if the protagonist wears gloves or a rain coat while wielding a weapon, she won't leave her fingerprints. The player can also frame another student by getting their fingerprints on a weapon.

Concealment

Some weapons can be easily concealed, while others cannot. the protagonist cannot use a non-concealable weapon when fighting against NPCs, 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 and carried inside a Cello Case, a Trash Can, or a Weapon Bag. Concealable weapons may be put in a container as well.

Killing animations

Each weapon has four killing animations, depending on sanity:

• Stealth kill: Performed from behind, with the victim unaware. Quick, quiet and clean.
• High sanity kill: Efficient, but not as fast as a stealth kill. Produces some extra noise and blood. Takes two seconds.
• Medium sanity kill: The victim struggles a little bit. The kill is sloppy and messy, taking more time. Takes four seconds.
• Low sanity kill: Very prolonged killing animation that is brutal and sadistic. Victim screams and struggles to get away. The player has the option to make the protagonist continue to attack her victim indefinitely by mashing the "attack" button, causing a segment of the animation to loop until the player stops mashing the button. Takes six seconds if not prolonged by button mashing.

Low sanity kill animations last longer than high sanity ones.

More animations could show additional kill techniques that vary depending on weapon type and current sanity level. 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.

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.

Knife-like weapons (short sharp)

Currently, only these weapons can be used for self-defense in struggles.

All knife-like weapons are small and can be easily concealed. However, if the protagonist uses one of them, she will get blood not only on weapons, but also on her clothes and the ground. Another disadvantage is that these weapons, except the makeshift knife, can be spotted with a metal detector.

When the "Knife only" restriction is enabled, the player is allowed to use only these weapons.

Weapon		Suspicious?	Can be picked by a student?
	Knife	Yes (unless you're a Cooking Club member and carry it in the Cooking Club)	No
	Scissors	No	Yes
	Box Cutter	No	Yes
	Screwdriver	No	Yes
	Ritual Knife	Yes	No
	Syringe	Yes	No
	Makeshift Knife	Yes	No

Big stabbing weapons

These weapons cannot be concealed or used in struggles. Using them always makes a huge splash of blood that gets on clothes and on the ground. Some of these weapons have additional features (i.e. the circular saw can be used for dismemberment).

Weapon		Suspicious?	Can be picked by a student?
	Medieval Sword	Yes	No
	Saber	Yes	No
	Katana	Yes	No
	Scrap Metal	Yes	No
	Circular Saw	Yes	No
	Scythe	Yes	No

Bludgeoning weapons

These weapons get bloody only during front attacks, and never leave splashes of blood on clothes or the ground. As of 2024, this has been partially changed and if the player performs a front attack with any of the weapons listed down below, the attack will result in the protagonist getting blood on her clothes. However, they can't be concealed or used in self-defence. Some of them can be carried through a metal detector.

Weapon		Suspicious?	Can be picked by a student?
	Baseball Bat	Yes (unless you're a Sports Club member)	Yes
	Dumbbell	Yes (unless you're a Sports Club member)	Yes
	Magical Girl Wand	Yes (unless you're a Drama Club member)	Yes
	Guitar	Yes (unless you're a Light Music Club member)	Yes
	Axe	Yes	No
	Old Axe	Yes	No
	Shovel	Yes (unless you're a Gardening Club member)	Yes
	Pipe	Yes	No
	Pipe Wrench	Yes	Yes
	Fire Extinguisher	Yes	Yes
	Manhole Tool	Yes	No
	Crowbar	Yes	No
	Bokken	Yes	No
	Shinai	Yes	No
	Thinker Statue	Yes	Yes
	Battle Axe	Yes	No
	Spiked Mace	Yes	No
	War Hammer	Yes	No

Strangulation weapons

Currently, these weapons leave no evidence. However, you can strangle the victim only when you're standing behind them, and the process of strangulation lasts longer then other stealth attacks. They cannot be used for self-defence.

Weapon		Concealable?	Suspicious?	Can be picked by a student?
	Garrote	Yes	Yes	No
	Stethoscope	No	Yes (seen as stolen)	Yes
	Necklace	Yes	No	Yes
	Measuring Tape	Yes	No	Yes
	Earphones	Yes	No	Yes
	Jump Rope	No	No	Yes

Possibly Planned Weapons

Weapons that might be added in future builds:

• Butcher Knife.

• Painting Knife.
• Soda Cans.
• Gardening Shears.
• Glass Cutter.

There will be different types of weapons in the future, such as two-handed, swinging, stabbing, and strangling weapons.

Bugs

• After the player washes a weapon after getting bloody, it will still count as a "bloody weapon" at the end of the school day.

Trivia

• 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.
• There are more weapons available in the small town, but they are currently not implemented.
• YandereDev has stated in an interview that the katana might be something that Kocho Shuyona confiscated and just never got rid of.
  • As of the November 15th, 2016 Build, the katana is located in the Headmaster's office.
  • The headmaster was said to have never touched the katana since 1988.
• Ranged weapons will most likely not be in the game. This is likely to prevent the game from becoming too easy, as nobody has defense against any ranged weapon (like a helmet). For example, with a sniper rifle/crossbow or even a pistol (which is easily concealable), all what one needs to do is to shoot, hide, then dispose of the weapon. It can be said that even without a silenced weapon, it is extremely easy to win Senpai by killing all the rivals. The game is also a school environment, so most likely very few opponents will ever get to use a ranged weapon that definitely requires another to defeat.
  • However, while the player cannot use any, there are NPCs with ranged weapons. The main example is the headmaster, who owns a taser that immediately causes a Game Over and has a longer rage than any other weapon.
  • Though the police are never seen with any ranged weapons, they might carry a pistol at the very least for security purposes.
  • Additionally, YandereDev does not want to add ranged weapons to the game due to the sharp increase in school shootings in the United States in the past decade.
• 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 the protagonist wins a fight against a Heroic student and another when 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 the protagonist.
• the protagonist intends to kill when the player presses the "attack" button. There is no chance of knocking the victim unconscious or leaving them "half-dead".
• There is a possibility that a sniper mini-game will be added purely for fun. However, a sniper equivalent in the game is unlikely. With one, it will harm the gameplay experience since the weapon will likely sustain against several rivals before it risks discovery by Senpai.
• It is very important to YandereDev that there's a cheat code or Easter Egg which unlocks a giant sci-fi energy scythe.
• In the future, it is possible that if students see a certain weapon lying around, they will give it to a teacher.
• YandereDev does not have the animations nor the models for choking someone with a rope or a chain yet.
• Cleaning bloody weapons can be done using a sink and the Drinking Fountains.
• YandereDev's favorite weapon is the cyborg ninja sword.
