Holding the Ritual Knife. June 3rd, 2016.

The ritual knife is a weapon and a tool used to summon demons in Yandere Simulator. It is not to be confused with the knife.


The ritual knife is found inside the Occult Club, placed in the forehead of the skull on the altar. The ritual knife is seen as suspicious and can be concealed. If a student sees Ayano Aishi holding the ritual knife, her reputation will drop by ten points at high School Atmosphere.

If Ayano kills a student with a ritual knife and places it back into the skull on the altar, she will start a Demonic Ritual.

In the future, if a student spots Ayano holding the weapon while she is not part of the club, she will be called a thief and it will be taken away from her. Student AI and path finding will have to be revamped before this happens.[1]

Ritual Knife Animations

There are 4 killing animations for the ritual knife depending on Ayano's level of sanity.

  • High Sanity: A swift stab to the right side of the head.
  • Medium Sanity: The victim tries to defend themselves, then gets stabbed in the right shoulder, then gets stabbed in the right side of the head.
  • Low Sanity: She will grab the victim's neck and tackle them to the ground, the victim will try to defend themselves, as they are stabbed in the head multiple times.
  • Stealth Kill: She will cover the victim's mouth, then stab them in the head.


What kind of weird knife is that? What are you going to do with that thing?!

  • On Druelbozo's Deviantart, more color variations of the ritual knife are available. This was so YandereDev had more options of which knife to choose from.[2]
