After using the \ debug command.

Study points are a way to increase stats in each of Ayano Aishi's skills in Yandere Simulator.

When Ayano goes to class, she will receive a number of study points that the player can use to spend in each school subject. The number of study points she receives depends on her punctuality. Normally, she receives five study points when going to class on time or ten study points if she wears the Old Fashioned Fundoshi panties. The game is structured so that if Ayano attends class every single day on time for the next ten weeks, then on the final day, she will have maxed out all her school subjects.[1]

To level up a skill, the player must allocate twenty study points in a skill category. Each skill, when leveled up, will open up more methods and buffs for Ayano to eliminate students.

As of the April 15th, 2016 Build, if Ayano is in the Gaming Club, she can play an educational video game to temporarily raise one of her subject levels for a day.


If Ayano arrives late to class, she will be scolded by her teacher and will be able to spend fewer study points, the deduction depending on how late Ayano is. Ayano will get a warning on her HUD when she is late for class. 

On time: Five study points.

8:31 AM - 10:00 AM: Four study points.

Please, try to make it to class on time. Take your seat.

10:00 AM - 11:00 AM: Three study points.

If you're late for class I must mark you as absent. This will affect your grades.

11:00 AM - 12:00 PM: Two study points.

You obviously don't care about your education.

12:00 PM - 1:00 PM: One study point.

Why do you even come to school?

Class Subjects


Focusing on Biology will teach you the weaknesses of the human body, unlocking new abilities, and enabling you to kill your victims more efficiently, resulting in less blood.
— Summary of Biology.
  • Rank 2: Ayano will be able to tranquilize any female student using the tranquilizer found in the infirmary. This can only be done in the gym's right storage room.
  • Rank 3: Currently unprogrammed.
  • Rank 4: Currently unprogrammed.
  • Rank 5: Currently unprogrammed.

In the Biology summary, it is stated that Ayano will be able to commit less bloody murders. This feature has not been added yet.


Focusing on Chemistry will allow you to construct chemical weapons.
— Summary of Chemistry.
  • Rank 2: Ayano will be able to locate poison in the school's chemistry lab and poison any student's bento during lunch time.
  • Rank 3: Currently unprogrammed.
  • Rank 4: Currently unprogrammed.
  • Rank 5: Currently unprogrammed.

YandereDev has spent no time planning or thinking about chemical weapons in the game. Being able to construct chemical weapons may change in the future.[2]


Focusing on Language will allow you to write fake love letters, write fake suicide notes, and impersonate other students through writing.
— Summary of Language.
  • Rank 2: Ayano will be able to write a note after faking someone's suicide and place it by their shoes on the rooftop.
  • Rank 3: Currently unprogrammed.
  • Rank 4: Currently unprogrammed.
  • Rank 5: Currently unprogrammed.

It may be possible that, if her Language skill is high enough, she will be able to call in sick to skip a day of school.[3] It could also factor in what she is able to say to the guidance counselor.[4]

Physical Education

Focusing on Physical Education will increase your running speed, allow you to end physical confrontations faster, and allow you to run while carrying a corpse.
— Summary of Physical Education.
  • Rank 2: Ayano is able to carry corpses in her arms and run while carrying them. (Very Weak)
  • Rank 3: Ayano's running speed increases. (Weak)
  • Rank 4: Ayano's running speed increases. (Strong)
  • Rank 5: Ayano's running speed increases. (Very Strong)
  • Rank 6: Ayano's power is maximum. (Peak Physical Strength)

As of the June 15th, 2016 Build, Ayano can carry five dumbbells at once if she is Rank 2 or above. In the future, it may be possible for Ayano to kill a student with her bare hands if she has zero sanity and her P.E is maxed out.[5] If all her physical education is maxed out, Ayano will be able to run six meters per second, if not combined with anything else.[6]

Focusing on Psychology will boost your reputation gain, lessen your reputation loss, and strengthen the effect of your gossip.
— Summary of Psychology.
  • Rank 1: "Now that you have reached Psychology Rank 1, you... well, honestly, Psychology doesn't do anything yet. The game is not done yet." (Currently unprogrammed)
  • Rank 2: Currently unprogrammed.
  • Rank 3: Currently unprogrammed.
  • Rank 4: Currently unprogrammed.
  • Rank 5: Currently unprogrammed.

In the future, a higher Psychology rank could possibly allow Ayano to torture her victims more efficiently.[7] Later on, it might also grant boosts, benefits, and buffs to social interactions.[8]


  • As of the April 15th, 2016 Build, there is a Stats menu where the player can look at Ayano's current subject levels.
  • There may be more class subjects, but the number of subjects depends on game design rather than budget, along with Q&A feedback.[9]
  • Currently, resetting the day does not reset study points, meaning that the player is able to max out every subject if they reset multiple times.
  • It is possible that in the future, Ayano will sound less "robotic" and more "human" if her Psychology or Language levels are high enough, but multiple voiced lines will be needed.[10]
  • In debug builds before the December 1st, 2015 Build, S was used to raise study points. In builds after it, S maxes out Seduction and Self-Defense instead. The button used to raise study points now is \ at the interface used to distribute points. Pressing P will bring the player one point away from maximum points in the Physical Education skill.
  • Weekends may be used to accumulate extra study points if a small town is not implemented.[11]
  • Pressing the \ debug command key while in class will upgrade Ayano's skills by one.
