1980s Mode is an official mode created for Yandere Simulator. It serves as the prequel to the game's main story mode, taking place in the year 1989.

Currently, the mode can be accessed directly from the title screen before the main menu has even appeared, in which the player can decide to play 202X mode or 1980's mode. Before its release, people thought that it could only be playable after beating 202X Mode for the first time.[1] And this mode could only be accessed through a save file that was used to beat the game.[2]

Description[]

In 1980s Mode, the main character is Ryoba Aishi, who is the mother of Ayano Aishi, as well as the yandere girl featured in the Mysterious Tapes.[3] Her appearance will resemble the Ayano from the save file that was used to start 1980s Mode.[2]

This mode only has technology that was available in 1989, along with stricter school rules. There is no internet, smartphones, Info-chan, or anything else that did not exist in 1989. The smartphone is replaced with a notepad, and students that witness a murder call the police using the landline phone in the Faculty Room. There is a Yakuza in this mode, unlike in 202X Mode. There is an optional filter that makes the game look grainier and older, much like a movie on VHS, to help represent the fact that this mode takes place in the 1980s. Basement Tapes 1-9 are meant to serve as the epilogue of 1980s Mode.[4]

The endings for this mode vary, but are determined by the player's "grade", or rank of how they played, eliminated the rivals, and dealt with homicide and any cleanup. The S+ rank unlocks the canon ending, but it can only be found if certain events play out beforehand.

Synopsis[]

The objective of this mode is to defeat 10 rivals, like in 202X Mode. However, the plot of 1980s Mode is not as elaborate as 202X Mode. For example, all the events between Jokichi Yudasei and the ten rivals are the same, but with different dialogue.

Every night, Ryoba Aishi was having recurring dreams for as long as she remembers about a certain boy; in those dreams, they fall in love, live their life together, and are happy. Ryoba thought this dream was showing her her future, and she was right. The boy who she was dreaming about, named Jokichi Judasei, was attending the same academy as her, Akademi. After realizing, she started to obsess over him, fantasizing about him every day, following him around all the time and investigating his interests and most deep secrets, and all without talking to him, not even once. Eventually, another girl started to show interest in this boy. Ryoba wouldn't allow anyone to take him away from her, and she will do anything to avoid that from happening. So that's why over the following 10 weeks, she will stop anyone who she thinks is threatening her relationship with him.

Differences to 202X Mode[]

  • The background music was completely remixed/remade in a synthwave style to match the 80s style.
  • Because smartphones did not exist in 1980s Mode, the pause screen was changed from a smartphone to a notepad. Instead of students calling the police on their phones, they will call the police on the landline phone located in the Faculty Room.
  • All Student's Profile on the pause screen are loaded up at the start of the game, as you cannot take pictures with a phone.
  • Ryoba Aishi's room is different from Ayano Aishi's room in 202X, and the video game console in her room is the "Mafukuru Entertainment System", which is a reference to the original Nintendo Entertainment System.
  • Info-chan did not yet exist, meaning it is not possible to see the schemes' steps. However, most schemes are unlockable at the start of the game. Some of the schemes must be unlocked by the serial killer in the town.
  • Ryoba is not threatening to Kocho Shuyona in this mode. If she encounters him, Kocho talks to her in a friendly way while in his office and will not try to tase her if she is close to him. However, he will tase Ryoba if he sees her carrying a weapon or a corpse in front of him.
  • Some of the students that were previously removed, such as the Rainbow Students, now appear in 1980s Mode.
  • Some of the electronics, such as the radio, are redesigned so they can fit the style of the 1980s.
  • All Student Council members were male in 1980s, and they are functionally identical to the 202X Mode student council.
  • The calendar screen now has "VHS aesthetic effects", and there's also a new menu called "Stats" where the player can see their actions, such as Rival Elimination Methods, in the previous weeks.
  • Ryoba will now be able to interact with the Yakuza in the town at night. However, the Yakuza will not speak with Ryoba unless she completed Togo Atatsuma's task.
  • The exclusive persona in 1980s Mode is the Snitch persona, which replaces the Social Butterfly and Phone Addict personas. The students with this persona will run to the faculty room and call the police on the landline phone if they discover a corpse or witness murder, and will stay there until the police arrive. This makes it impossible to kill them, as they will be surrounded by teachers.
  • The Journalist will be investigating Ryoba's suspicious behavior while walking in front of the school gate. If he sees Ryoba kill someone, being bloody, or carrying a weapon while standing too close to him, he will quickly run up to her and pepper spray her, resulting in a Game Over.
  • The Sociology Classroom is in place of the Gaming Club in this mode.
  • The Info Club has been changed into the Newspaper Club, which is now a fully-functioning club Ryoba can join.
  • There is a grade you will receive at the end, depending on the way you played the game.
  • There are now 10 delinquents instead of five, with half of them being female.
  • The Saikou laptops aren't present in the Meeting Room or the Student Council Room as laptops did not exist back then.
  • The player has access to a list of debug commands on the Calendar screen which allow them to change the events of the previous weeks, such as how they eliminated their rivals.
  • The player cannot take photos as they don't have a smartphone. However, they can do so if they join the Photography Club as an old camera will be provided to them.
  • Since wireless headsets didn't exist in 1989, the player has to give a suitor advice before the daily interaction for the matchmaking process, and learn the outcome afterwards.

Rivals[]

Ending[]

Determination[]

The "rank" given at the end will depend on your "guilty points" and "innocent points".

Guilty Points[]

  • The police are called to school: +1 Guilty Point per visit.
  • The police discover a corpse on School grounds: +1 Guilty Point per corpse.
  • Student catches Ryoba doing something suspicious: +1 Guilty Point per student. If Ryoba is spotted in Jokichi's aura, she will NOT receive a guilty point.
  • Student accuses Ryoba of murder: +20 Guilty Points per student.
  • The rival's death is judged to be a murder:
    • the murderer is unknown: +10 Guilty Points.
    • another person is believed to be the murderer: No Guilty Points.
    • The rival's death is considered to be an accident / she has gone missing: No Guilty Points gained.

Innocent Points[]

  • Befriend a student in school: +1 Innocent Point per student.
  • A befriended rival testifies that Ryoba would never be a killer: +10 innocent points.
  • Each reputation point is worth +1 innocent point, with a maximum of +100 reputation points available to Ryoba.

Canon Eliminations[]

As for Rank S+, Ryoba will hint at the beginning of each week how she wants her rival eliminated:

  1. Kaguya Wakaizumi: Sabotage her interactions with Senpai so he'll reject her love confession.
  2. Moeko Rakuyona: Burn her to death and make her death look like an accident.
  3. Honami Hodoshima: When she enters the library, push a bookshelf on her, crushing her to death. Her death will be considered an accident.
  4. Sumiko Tachibana: Poison her bento using lethal poison. Her death will also be considered an accident.
  5. Ritsuko Chikanari: Put a sedative into her bento, wait for her to sunbathe after school, and push her lounge chair into the school pool to drown her as she is sleeping. Her death will be considered an accident.
  6. Ai Doruyashi: Have her electrocuted to death during her daily performance on stage in the school's gymnasium. Her death will be considered an accident.
  7. Teiko Nabatasai: Have her expelled from school. Framing her for possession of Narcotics will not be counted, as she will get arrested afterward.
  8. Komako Funakoshi: Gossip about her until her reputation reaches -100 or below. This will cause her to withdraw from Akademi. If her reputation reaches -150 or below, she'll kill herself, which does not give you S+.
  9. Chigusa Busujima: Matchmake her with her suitor, Etsuji Odaka.
  10. Sonoko Sakanoue: Befriend her and ask her to stay away from Senpai.

Following through with each specific elimination and earning at least 100 more innocent points than guilty points will earn you rank S+. It will also unlock a bonus cutscene at the end of the game as well as a timeline.

Alternative Canon Eliminations[]

For some rivals, you don't need to eliminate them in a specific way. You can use alternative methods and can still get S+ rank (Note: These elimination methods might not get you S+ rank in future versions of the game):

  1. Moeko Rakuyona: Splash her with a bucket filled with Gasoline and get a candle or a bunsen burner and approach her before she takes a shower in the Shower Room to burn her.
  2. Honami Hodoshima: Crush her by dropping a heavy weight from the school rooftop.
  3. Ritsuko Chikanari: Poison her bento with rat or emetic poison. After she ate her bento and ran to the nearest bathroom, drown her in the toilet while she's throwing up.
  4. Ai Doruyashi: She doesn't need to be electrocuted during her performance. You can electrocute her at any time using any method, such as with a car battery, at a water drinking fountain, or poisoning her bento and sabotage the sink while she's throwing up.

Ranks[]

At the end of the game, if you have more guilty points than innocent points, you'll be found guilty of murder and earn Rank F. If you have at least 100 more innocent points than guilty points, you'll be found innocent, free of suspicion and earn Rank S. Anywhere between these two and you'll earn Rank A, B, C, or D.

Alternate Timeline[]

In this timeline, Ryoba confesses her love to Jokichi Judasei without interruptions, avoiding the trial and any kind of suspicion that people may have in her.

Ayano's basement with postcard pop-up

Postcard at 202X's basement.

Step by step[]

  1. To activate this timeline, the player needs to go to 202X's basement and look around to find a postcard. It will be located at the right corner behind the stairs.
  2. Read the postcard and remember the phone number written on it.
  3. Then, the player has to go back to 1980's mode, and at the beginning of the tutorial, instead of following the instructions, go to the Faculty Room.
  4. The player will find a phone at the left of the desk, when interacting with it, Ryoba has to call the number found before.
  5. Fun Girl will appear and explain the situation to Ryoba.
  6. The player has to follow the instructions given by her:
    1. Grab balloons (found at the backstage in the GYM) and ammonium (found in the Science Lab).
    2. Go to the Workshop to craft Stink Bombs.
    3. Go to the Cooking Club and throw the Stink Bombs at Ui Tunesu.
  7. Then, continue to follow the normal instructions from the tutorial.

Gameplay[]

In the speech of the fun visitor, the player will be given certain instructions that need to be accomplished to get the "Alternate Ending" throughout the following 10 weeks:

  • The player can not kill anybody.
  • The player has to eliminate the rivals without ending their lives.
  • The player needs to have the best reputation at school.
  • The player has to leave romantic notes and gifts in Jokichi Judasei's desk.

If the player doesn't accomplish this tasks, Fun Girl will destroy the timeline permanently.

Not following instructions[]

If the player doesn't cooperate and doesn't follow the instructions given, at the time Fun Girl notices a mistake and after the "End of the Day" sequence, she will immediately speak to Ryoba, saying that she failed to follow the rules:

  1. Ha ha ha...
  2. You Idiot!
  3. You ignored my instructions.
  4. This timeline is now a "Dead End."
  5. I will now erase you...and this timeline.


After the speech, Fun Girl's sprite will become bigger, approaching the screen, and then the game will crash. When going back to the title screen, the save file the player has been playing on will be gone, deleting all the progress.

Non-Lethal Elimination Methods[]

This Elimination methods can be used to eliminate the rivals without killing them, successfully finishing the Alternate Timeline.

Differences[]

  • While playing the game, instead of the speech Ryoba gives every Saturday about the upcoming rival, Ryoba will always say this:
    • "Another rival has appeared." "I can't let her take Senpai from me." "I must eliminate her before 6:00PM on Friday." "I'm not worried. I have full confidence in my ability to stop her..." "I just have to keep following the instructions I received from that phone call."
Ryoba speech alternate timeline
  • On every Saturday's speech, Fun Girl will appear floating around the screen, almost unnoticeable because of her transparency.
  • In the tutorial, after disposing of the bloody clothing, Ui Tunesu will not ask Ryoba about the knife she took from the Cooking Club.
  • After the tutorial, the police will not be called.
  • The journalist is not investigating Akademi in this timeline.
  • The Student Council's members are not alert or conscious about a murderer in school, so they will not push Ryoba and will not turn around when walking or running behind them (It's still impossible to interact with them).
  • Chigusa Busujima is the last rival, Sonoko Sakanoue doesn't have any motive to go back to Akademi.
  • Instead of the judge, the one who decides the fate of Ryoba depending on the player's decisions is Jokichi.

Ending[]

At the end, Ryoba finally confesses to Jokichi without any interruption. Then, Jokichi judges the player's actions to decide whether or not he accepts Ryoba's feelings.

He will take the following subjects into consideration:

  • The methods used to eliminate every rival.
  • The amount of interest he has about his secret admirer.
  • Ryoba's reputation at school.
  • If he has experienced any kind of trauma or any situation that resulted alarming to him.

Trivia[]

  • At the beginning of the game, because of the murder of Sumire Saitozaki (the tutorial rival), the headmaster prompted the school to force faculty members to undergo self-defense training.
  • The idea for 1980s Mode occurred when someone complained that they did not like Info-chan and wanted a mode without her.[5]
  • YandereDev would like help from volunteers to make period-correct outfits and hairstyles for the 1980s.[6]
  • The Journalist appears in front of the gates at school and in multiple cutscenes.
  • Senpai's parents do not appear in this mode.[7]
  • This mode is meant to be the most difficult mode. It may include the player getting a Game Over if a witness escapes, since in the Mysterious Tapes, the yandere of 1989 was arrested with no hard evidence.[8]
  • YandereDev has stated that he will attempt to give this mode the same vibe as "a peaceful countryside Japanese town in the late 80s".[9]
  • This mode is ten weeks long.
  • The outcome of this mode will not affect the story.[10]
  • Genka Kunahito's mother, Mae Kunahito, appears in this mode.[11]
  • The overwhelming majority of the new music in 1980s Mode was created by one person, CameronF305.[12]
  • While passing time, Ryoba looks at a polaroid of Jokichi, rather than a phone.
  • Canonically, half the rivals were killed, and the other half were eliminated peacefully.
  • 1980s Mode is currently the only mode where Ayano does not appear as a playable character as she did not exist yet.
  • Mission Mode is available since in the alternate universe, The Yakuza sent Ryoba to kill people.
  • Originally, there was going to be a rival for 1980s mode who was a shy and antisocial girl who had trouble communicating with others. She wanted to become a meteorologist after she graduated, so she would spend most of her time outdoors near meteorological equipment, studying the weather. During her week, there would be a lightning storm. While all the other students would go inside, she would stay outside in the rain next to her meteorological equipment to study the thunderstorm and gather data. There would have been an event where you would sabotage her equipment so it would overload and electrify her. Ryoba would frame this as a lightning strike, as you'd make it look like she was struck by lightning while studying the lightning storm. In the end, this concept was rejected because it would have taken too much time to set up a weather system for just one day.[13]
  • As of the 2nd May, 2023 build, all the rivals have now their own tasks. Their routines were also updated.
  • Eliminating a rival non lethally and then killing them on a later week will NOT give you any guilty points, as "Ryoba's involvement [will not be] suspected."
  • There is a bug that if you open 1980s Mode and 202X Mode at the same time Ayano will wear a 1980s uniform and the other students will wear normal uniforms. 1) If you open the Schedule, Student Profiles from the 1980s will appear. 2) If you open the Students Info Screen and click on one of the student profiles, the photos that appear are students from the 1980s. 3) The Player doesn't need to get Senpai's photo to speed up time. 4) The Player can't access the camera on the 202X unless they join the Photography Club and get an old camera from the 1980s. 5) If the Player kills Raibaru on the first day with poison, when Osana discover the corpse she will run towards Senpai and run out of school instead of crying next to the corpse or calling the police.
