Nemesis (born Hanako Yamada) is a student who is exclusive to Mission Mode and the Horror Prototype Easter Egg.

She presents a "lethal obstacle" to Ayano.[1]


'Mission Mode' takes place in a separate timeline from the main game. In Mission Mode, you play as a young female assassin who has been contracted to kill a student at school. However, you aren't the only killer at school...

Nemesis is a character who attempts to hunt and kill you during Mission Mode. It is impossible to kill her with a frontal attack; if you want to kill her, you need to approach her from behind. If you run, she will hear your footsteps, so you must be very careful and quiet if you wish to sneak up on her. Depending on what difficulty level you have chosen, Nemesis might be invincible, and might also be disguised as one of the female students.

So, just who is Nemesis? Is she a bodyguard hired to protect the student that you're after? Is she a vigilante who has made it her mission to stop you? Is she another assassin who wants to remove her competition? Or, true to her namesake - the Greek goddess of retribution - is she here to take revenge on the protagonist for the sins of her past? For now, it's a complete mystery..."[2]

As of August 1st, 2019, it was revealed that Nemesis is Taro Yamada's younger sister, Hanako Yamada, in the Mission Mode timeline. In this timeline, Taro was Ayano Aishi's first target she assassinated, and Hanako swore to punish her brother's killer.[3]


She wears the default female school uniform for Mission Mode, which is the fifth female uniform available.

Nemesis has pale skin, rounded straight black hair, and thin red eyes. Her fists are always clenched and she wears black gloves. She used to have spiky wavy hair, similar to Oka Ruto's hair, which changed into a bowl haircut. This is her third hair style.

If the player chooses to have Nemesis disguised, she will take on the appearance of a random female student in school, bar the Student Council members, the Bullies and Club Leaders.


YandereDev pictures Nemesis wearing a very grim and serious facial expression at all times, and being very emotionless and solemn. In almost any situation, she would have a deadpan look on her face. However, the moment she goes in for the kill, her expression may change to reveal her true nature.[1]


Nemesis about to kill Ayano Aishi by stabbing her in the head. January 16th, 2017.

She only appears if enabled in Mission Mode. At 7:00 AM, Nemesis will spawn randomly inside the school and will start wandering around the school corridors and courtyard, searching for Ayano. If disguised, she will enter the school grounds as a female student, but will turn hostile after changing her shoes at the lockers.

When noticing Ayano, she will break her routine and start following Ayano in an attempt to kill her with a knife. If aggressive, Nemesis will always run to Ayano, everytime she sees her. Her running speed is faster but Ayano can still outrun her, but it will be also difficult to make Nemesis lose her sight on Ayano.

She does not go to class.

If the player opens up the Horror Prototype by using "F2" in the Easter Egg menu, the school will be set at the lowest atmosphere. Nemesis, like in Mission Mode, will spawn randomly in the school, looking for Ayano. She will not be disguised as a female student.


  • Pointing the camera at Nemesis when she kills Ayano will clip her face through the camera with the game over text overlapping.
  • Nemesis will spin in circles if led onto the running track.
    • The bug no longer exists as the school environment has been shrunk.
  • Nemesis will spin in circles if Ayano is standing in front of a hiding spot.
  • Nemesis cannot be cauterized or dismembered.
  • Under certain conditions, Nemesis will stand still.


  • When on a mission, Ayano may specifically not be permitted to kill Nemesis.[4]
  • She was implemented in the December 16th, 2016 Build.
  • Nemesis can only be killed from behind.
  • Nemesis is able to hear Ayano's footsteps whenever she is running, so Ayano must walk, crouch or crawl in order to kill her.
  • If the player sends Info-chan a photo of Nemesis, she will respond with, "Strange. I have no profile for this student."
    • For the 2nd time, she will respond with, "...wait. I think I know who she is."
    • For the 3rd time, she will respond with, "You are in danger. Avoid her."
    • For the 4th time, she will respond with, "Do not engage."
    • For the 5th time and beyond, she will respond with, "I repeat: Do. Not. Engage."
    • If Nemesis is disguised as a female student, Info-chan will respond with, "Something about that student seems...wrong."
    • When sending a picture of Nemesis' panties, Info-chan will respond with, "Wait...I recognize those panties! This person is extremely dangerous! Avoid her at all costs!"
  • She is the only character that can kill Ayano.
  • When she was first introduced, Nemesis was referred to as 'Nemesis-chan'.[5] YandereDev has since confirmed that her official name is 'Nemesis'. He chose this because he thought the name 'Nemesis' sounded far more ominous.[6]
  • Nemesis is the name of the Greek goddess of revenge and divine retribution and the word for one’s arch-enemy.
  • YandereDev imagines that, when Nemesis is disguised as a student, the original student was knocked out and stuffed into a container on their way to school.[7]
  • It is possible that she wields a ceramic knife in order to not be detected by the metal detector.[8]
  • On his blog, YandereDev has decided to change Nemesis' current hairstyle, as the artist of the illustration he took inspiration from was uncomfortable with how similar the current Nemesis and her illustration was.[9]
    • As of the January 16th, 2017 Build, her hairstyle is now the third option that fans voted for.
  • Nemesis' temporary hair model was the 'Bobcat' hairstyle without the tufts.
  • If a Student Council is the person who Nemesis disguised as, they will be simple to spot. They won't look at you if you get too close to them, their idles will not be used, and will keep on walking if Ayano's phone is pointing at them.
  • While Nemesis is aggressive, she runs the same way as in Enigma mode, one of the Easter Eggs.
