Pippi Osu is one of the female students that currently attends Akademi High School.

Pippi is the first student to be introduced as an Easter Egg.


Pippi wears the default female school uniform, unless customized by the player.

Pippi used to have short neat black hair with a pink fringe, which was a placeholder.[2]

As of the October 8th, 2015 Build, Pippi has short, black hair, accompanied by a pink fringe. A thin, and single, pink strand lays on her forehead. Her eyes are emerald green. Unlike other students, she wears short socks. Her bust size is 1.

As of the August 18th, 2018 Build, Pippi wears a red bandana around her neck.

Among the personas currently implemented in the game, Pippi is a Phone Addict. She will happily pose for a picture if Yandere-chan aims her camera at her. If she sees a corpse or witnesses a murder, she will snap a picture with her Phone and will text it to the police. While she is doing this, she will run out of the school.

She enjoys playing video games more than socializing with the other students. According to her Student Profile, she is unlikely to witness murder unless it takes place in the Computer Lab.


As of the August 18th, 2018 Build, Pippi enters the school grounds at 7:05 AM. She walks to her locker at 7:10 AM and changes from her outdoor shoes to her indoor shoes. At 7:15 AM, Pippi plays an augmented reality game with Midori Gurin, Ryuto Ippongo, and Mai Waifu.

At 8:00 AM, Pippi walks into Classroom 2-2 and sits at her desk. She starts her morning classes at 8:30 AM, and leaves to go to the rooftop at 1:00 PM.

Pippi walks back to class again at 1:30 PM and participates in cleaning time between 3:30 PM and 4:00 PM. Afterwards, she continues playing the augmented reality game until the rest of the day.

Pippi's used copy of the Yanvania re-release always crashes right after the first boss. She will ask the player to take the disc home and play it, to see whether there's a problem with the disc or her console. After playing past the first boss, the game will crash. The next day, Pippi will thank the player and tell them to keep the disc.


Ryuto Ippongo

Main article: Ryuto Ippongo

Pippi has a crush on Ryuto according to her student profile, but she doesn't know that he feels the same way.

Since she has a crush on him, if the player kills Ryuto in front of her, she will attack the player with much more force than she's usually capable of. However, if he dies, she will not mourn his death.


  • Pippi was implemented in the May 24th, 2015 Build. She was the first student who had hair in two different colors.
  • Pippi is the mascot of the popular rhythm game, osu!.

    Pippi, the official mascot of the game osu!

  • Pippi plays osu! when she is in the Computer Lab. As of the August 12th, 2015 Build, the song that plays in her game if Yandere-chan stands close to her is the remix of the song that plays when Yandere-chan is sane, which also gets distorted as she goes insane.
    • Before the August 12, 2015 Build, when Yandere-chan stands close to Pippi, she could hear the theme song ("Connect" by ClariS) of the anime Puella Magi Madoka Magica play.
    • On her screen is Tomoe Mami, a main character in the anime Puella Magi Madoka Magica.
    • On the computer, the player can see she is playing osu!. In the actual game, there are four gaming modes; Standard, Mania, Taiko, and Catch the Beat. Pippi plays Standard mode. She looks to be playing at a hard difficulty.
  • Before the June 29th, 2016 Build, Pippi arrived on school grounds 14th in line on the right side, at 7:05 AM.
  • YandereDev used to consider Pippi to be his 2nd punching bag, number one being Kokona Haruka, since she was the last student to arrive at school. No student could witness her death if she was killed when walking to school. Now that there are more students that arrive later than Pippi, she can't be killed easily without being seen.[3]
  • YandereDev has permission from Pippi's creator for Pippi to be in the game.[4]
  • YandereDev might implement Pippi blushing when she is near Ryuto.[5] She may fall into depression if he dies.[6]
  • If YandereDev decides to have student nicknames, then her real name would not be Pippi Osu and would instead be a nickname given to her, due to her affinity for 'osu!' and her dyed hair.[7]


What is a Senpai?
— Pippi Osu in "I Want My Senpai Back".
I bought a used copy of the Yanvania re-release, but the game always crashes right after the first boss! I'm not sure if there's a problem with the disc, or if there's a problem with my SaikouStation 4... Would you please take this disc home with you, play it, and tell me if the game crashes after the first boss?
— Pippi asking Yandere-chan to take home and play her disc.
You'll do it? Thank you so much! I really appreciate it!
— After accepting her task.
Oh! Oops! I guess I shouldn't have just presumed you'd have a SaikouStation4...sorry...
— After denying her task.
So, it crashed for you too, huh? Well, now I know there's nothing wrong with my SS4. You can keep the disc. Thanks for your help!
— After completing her task.
