Easter Egg menu as of June 1st, 2019.

Easter Eggs are fun surprises in Yandere Simulator that the player must discover in order to use.

YandereDev has included many Easter Eggs in the debug builds of the game. They include wearable accessories for Ayano Aishi, game modes, a small timed event at the starting menu, references to several anime characters or in-game jokes, and a phantom. The final game may have cheat codes that change the appearance of the characters, like the Easter Eggs do.[1]

There is a piece of cheese near a mouse hole at the bottom of the room. When examining the piece of cheese, words will come up on the HUD, saying, "Knowing the mouse might one day leave its hole and get the cheese...It fills you with determination." This is a direct reference to a line from Undertale.

Book

At various times each day, Kuu Dere, Senpai, and Horuda Puresu will walk to their respective places and read a book. Study-kun B used to read the same book in the library. This book contains simple information on Yandere Simulator's premise.

Development of Yandere Simulator began in 2014, with YandereDev releasing test builds of the game for debugging purposes. He has periodically released updates that add elements to the game, such as the ability to poison, electrocute, and drown rivals, stealing other female students' uniforms to change into after committing a murder, befriending other schoolgirls, small mini games, a town the player can bike around in, and more. I hope the game's out before 2019.

Players control Ayano Aishi, a Japanese schoolgirl who has developed a crush on a fellow student when she bumped into the boy currently named Taro Yamada, nicknamed "Senpai". Over the course of 10 weeks, 10 rival students develop crushes on Senpai, and Ayano must prevent them from confessing their love to him. Due to her "yandere" nature, this can be accomplished by the player via several methods such as murder, blackmail, or social sabotage. Throughout the game, Ayano can receive aid from an information broker calling herself "Info-chan", who can provide her with services such as weapons, plans, or other favors in exchange for panty shots. Ayano must also avoid being witnessed while performing criminal activities, or suffer penalties ranging from a loss in reputation that makes it harder for other students to trust her to an immediate game over. Murdering students will result in penalties to "School Atmosphere", which alters NPC behavior to become more suspicious and riddled with anxiety. During this time, she can join school clubs and attend classes to receive additional abilities such as easy access to weapons or increase abilities to avoid suspicion.

Hello. He-he-he-he-have some respect and don't spoil the game. It's impossible to have mysteries nowadays, because of nosy people like you. Please keep all of this between us. If you post it online, I won't make any more secrets. No one will be impressed. It will be your fault! He-he-he-he-ha-he-he-ha-he-he.

 
— The text of the book.

The last paragraph is a reference to the Undertale game file, "abc_123_a.ogg", in which listeners are asked not to spoil the game for others.

Abc 123 a

Confession Tree Voice

If Ayano steals Sakyu Basu's ring at lunchtime and then goes to the Confession Tree behind the school, a female voice will say "...that...ring...".

Delinquents

Between the April 15th, 2017 and April 26, 2018 builds, if the player pressed the Space Bar ten times in front of the placeholder delinquents, they donned Team Skull masks and danced slowly.

Fun.txt

Main Article: Fun Girl

The Fun.txt was added into the Streaming Assets folder as of the February 8th, 2016 Build. Within the text was a single zero, which the player could change. Depending on the number entered, there would be several texts before the game usually crashes. Deleting this file does not have any effect on the game and it will run as normal. The file was removed in the January 4th, 2017 build, and readded in the April 2nd, 2018 Build.

Glowing Blue Eye

The left eye of the skull in the Occult Club will glow blue after viewing the cheese. This is another reference to Undertale, namely the character Sans, whose left eye also glows blue.

Pink Turtle

If Ayano goes to Mr. Jazzy Feet in the Light Music Club and asks him to forgive their sins 10 times, a pink turtle wearing a bow will appear alongside Mr. Jazzy Feet in his tank.

Rainey

If the player types out the word 'rainey' on their keyboard, a female student will appear in the Martial Arts Club just behind where Budo Masuta stands. She will wear the default uniform regardless of customization and has a long brown braid. She will slowly sway side to side.

Yandere Simulator Website Easter Eggs

Konami Code

  • If the Konami code (up, up, down, down, left, right, left, right, B, A) is entered on the "Characters" page, the page will become red and black. All the characters are replaced with one character, that being Fun Girl.

Characters Page

If the Konami code is entered on the characters page, the website's theme will become dark. All the current characters' profiles will be replaced by a profile of the Fun Girl. Her role, status, personality, appearance, and weakness will all be "?????". If the player hovers over her image, the page will start to turn to static and eventually the screen will go black. The Japanese text on the left says:

アラアラ...

あなた誰?

ふふ...

はじめまして。

私たちは一緒に多くの楽しみを持ってしようとしています。

Which translates to:

Ara ara ...

Who are you?

Fu Fu ...

Nice to meet you.

We are trying to have a lot of fun together.

If you entered it again, the screen will fade out quickly, turning black. The screen will turn red after a short pause, and multiple Fun Girls will start to flash on-screen. If entered again, the red background will turn black. The black background will last about 10 seconds before it turns red again. On subsequent code entries, the background will turn black, but only if the background is red. If it is black, it will not change to red when the code is entered.

Bugs

  • In DK Mode, it is difficult to mop up blood because the mop grows and moves through the floor when the player picks it up.
  • Long Skirt Mode will not work correctly for any uniforms besides the default one, as it glitches the textures.
  • If the player kills all the teachers and students in the school with an Easter Egg mode, at the end of the day, the game will still say that a teacher discovered a corpse.
  • When activating Naked Mode, Ayano will still be wearing her panties. To fix this, change into a different uniform in the locker room.

Trivia

  • If it becomes possible to choose Ayano's gender, then male-equivalent Easter Eggs will have to be created.[10]
  • There may be an Easter Egg where one NPC is secretly a magical girl, and there would be an opportunity to see her transform. It's a low priority, however.[11]
    • In addition, if Ayano manages to collect all ten Magical Girl Pretty Miyuki manga, she will unlock a magical girl Easter Egg.[12]
      • In the 31st October, 2018 build, this Easter Egg was implemented as Miyuki Mode, albeit with different requirements to activate it.
  • C was used to disable copyrighted music. With Cirno Mode now available, it has been shifted to D. M also mutes all of the game music.
  • YandereDev's favorite Easter Egg to create is Punished Mode.[13]
  • There may be a Sonic Easter Egg where Ayano is naked, covered in blue body paint, and moves at 10x speed.[14]
  • NPCs without an AI are not affected by any mode.
  • It was very important to YandereDev that some sort of cheat code or Easter Egg in the future will unlock a "giant sci-fi energy scythe".[15] It was later revealed to be the Cyborg Mode.
  • In the game's code, Info-chan's glasses are named KON glasses.[16]
  • Undertale has been referenced the most through Easter Eggs, with its references being the mouse hole and cheese, the skull with its glowing eye in the Occult Club, Bad Time Mode, the Fun Girl, and the book students read.
