Pippi is the first student to be introduced as an Easter Egg. Soon after, Midori Gurin was as well.

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

Among the personas that are currently implemented in the game, Pippi is a Phone Addict. She will strike a cute pose for a picture if Ayano aims her phone 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 obsessed with an augmented reality game called "Pretty Guardian Miyuki" that is about collecting "waifus" and hunting monsters.

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, the official mascot of the game osu!

  • She was implemented in May 24th, 2015 Build. She was the first student who had hair in two different colors.
  • She is the mascot of the popular rhythm game, osu!.
    • Her bandana might reference a look that Pippi has in osu!.
  • She plays osu! when she is in the Computer Lab. As of the August 12th, 2015 Build, the song that plays in her game if Ayano stands close to her is the remix of the song that plays when Ayano is sane, which also gets distorted as she goes insane.
    • Before August 12, 2015 Build, when Ayano Aishi stood close to her, the song "Connect" by ClariS, the theme song of the anime Puella Magi Madoka Magica, could be heard.
    • Mami Tomoe, a main character in Madoka Magica, could be seen on her screen.
    • 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. She plays Standard mode. She looks to be playing at a hard difficulty.
  • Before the June 29th, 2016 Build, she arrived on school grounds 14th in the line on the right side, at 7:05 AM.
  • YandereDev used to consider her 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 peppy (her original creator, also the creator of osu!) for her to be in the game.[4]
  • YandereDev might implement her blushing when she is near Ryuto Ippongo.[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 Ayano 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.
