Kellie Kaypopp is a student who appears in Yandere Simulator 2D.


Kellie has long brown hair and light blue eyes. She wears orange and blue striped stockings.


Kellie is known for warning people she will bring out the advice ball, and usually does. Some believe the advice ball might be the reason she can never be killed as it deflects attacks.

She also commonly calls strangers Grace or Trip.


Pippi Osu

Pippi was the first member of Gaming to meet Kellie. They get along well.

Ai Hayashi

Every morning Kellie sees Ai under a tree with Potato-kun and says "Hi, Grace!" to her.

Kitino Ashi

Don't make me bring out the advice ball!
— When trying to kill her in Yandere Simulator 2D.


  • She is a parody of the YouTuber KPopp.
  • She is an American transfer student.
  • Kellie's crush used to be Popptart Manlytart, however this was changed when she gained the Popptart persona.
    • Popptart Manlytart are the names KPopp gives her fans.
  • Kellie's name was changed from Kelly Kpopp to Kellie Kaypopp to be more parody-ish.
  • In the final version of Yandere Simulator 2D, killing her will unlock her stockings.
    • However, it will be extremely hard to kill her. She may be the only "regular" student with an exclusive elimination method.
  • The Science club has published a paper on Kellie's advice ball titled "A Scientific Study on the Advice Ball".
    • 95% of people hit with it are left unconscious, 4% can't walk for some time, and it's believed 1% probably die (no deaths are known, yet a 1% death-rate is listed on the paper)
    • The member in charge of the study, tried to find out what the advice ball was made out of. The paper quotes him saying, after being hit by her 20 times, "That ball must of been made by aliens. Though, further research is needed for a conclusive answer."
    • The paper states the ball weighs 70 pounds at the start, but at the end it states 5 tons. This has lead to several rumors about the weight.
    • The member that conducted this study is considered unreliable due to severe head injuries, and absurd claims about advice balls afterwards.
      • A group of people that have been hit by the advice ball state the paper is correct and that "Pro-Advice Ball Scientists are covering up the truth about the dangers of people named Kellie possessing them!"
