Although they are removed, YandereDev stated that they might back in 1980s Mode, similar to the original Delinquents. Also, he might add them back if the framerate significantly improves. He might add a cheat code to spawn them and use the Rival's slots, but it will be removed once the rivals are implemented.
These characters have only appeared in their respective games. Sakura appeared in Burning Love, Tsundere-chan and Kuudere-chan in Kuudere Simulator, Himedere-chan in Kuudere Simulator 2, and Osana Najimi in Kuudere Simulator 3.
Students sometimes get stuck on each other or the props.
If a student is beckoned by laughter, they may sit down, play games, or read once they reach their spot.
There may be a Kickstarter reward allowing a fan to create a student to be implemented into the official game.
It may be possible for the player to add their own students in the future.
There will be one character in Yandere Simulator who YandereDev has always envisioned as someone who tortures animals. However, it is not Yandere-chan.
If YandereDev could make a student based on himself, he would make a student who is in the Gaming Club, a Loner, and has no crush, unless he added a student who resembles his favorite video game character. Still, he has no desire to put himself in-game.
An NPC with Rival-chan's appearance might be in the final game.
There may be a student that looks like YandereDev, but is the complete opposite of him otherwise.
YandereDev would love to include a gothic lolita character.
Students with something noteworthy about them (such as rivals and Easter Egg students) might have ironic names.
In the future, when a student who wears glasses loses their glasses, their line of sight might be reduced.
There is a reason why the students will still come to school when they know there is a serial killer on the loose, but YandereDev has not released this information yet.
In very early debug builds, all students were recolors of Yandere-chan's model, with the only difference being the hair and eye color (light blue). Before students had names, they were all named "Student-chan" within the game code. They were given different hair colors in the February 15th, 2015 Build. Five corpses of "Student-chan" used to be seen on the title screen before the March 17th, 2016 Build, when they were changed.
YandereDev quickly makes students by modifying lines on an XML sheet and exporting the XML as a JSON file. Within the current game engine, however, he has to place all physical destinations where a student has to go. In the future, the game will automatically assign students' destinations.
There will be some comic relief moments in the full version of Yandere Simulator, during particular NPC conversations.
Some boys in the school are very big perverts, as they buy panty shots from Info-chan.
In the future, two "special" NPCs that are popular among fans may enter a relationship.
The player may be able to distract students with small firecrackers in the full game.
As of the September 20th, 2015 Build, students' clothes, hair, and animation codes are not active when Yandere-chan is far away. This is to improve frame rate.
Since Info-chan is a notorious name around the students, her default reputation will be -999. But her true identity will have a rep of "0", as no one knows who she really is.
The names of the first six male and six female characters are the most popular Japanese given names of 2012.
Pippi and Ryuto will be the only rhythm game references in Yandere Simulator.
A fictional anime called Magical Girl Miyuki will be popular among students, and they may talk about it occasionally. "Did you see last night's episode of Magical Girl Miyuki?"
YandereDev stated that he might even add a magical girl in the game for fun.
Students will have an age of "???". It is this way due to the fact that 16-18 year old students seen naked may be recognized as child porn.
Budo Masuta is the only fully programmed NPC who doesn't appear to be scared at low School Atmosphere. However, if the Martial Arts Club closes down, he will become paranoid.
YandereDev will only make parodies of characters that he cares or knows about.
YandereDev has stated that a Japanese teacher told him nobody at school would be openly LGBT and only come out after graduating.
However, Senpai, Yandere-chan, Yandere-kun, and the rivals will not be straight depending on what combination of those characters the player chooses.
YandereDev "has some plans for students who act as amateur 'investigative journalists'".
In the future, the delinquents will only willingly interact with the player if Yandere-chan's reputation is low enough. YandereDev believes that the delinquents should arrive at class late when they are fully implemented. They will not help the player with murder nor take the blame for it.
In the future, it's possible that if Yandere-chan gets too popular, some students may start to stalk her, meaning that any murders committed would have witnesses.
According to YandereDev, Yandere-chan would only befriend students for manipulative purposes.
YandereDev would love to keep the original 12 students in the game, but he might have to ditch some NPCs if the production puts limits on him.
There are two characters who have abused an animal once during their life. It is unknown if these characters are students or not.
YandereDev would like to rename some characters.
YandereDev may have the female students in the game act more like "real Japanese schoolgirls" and perform lewd actions such as sneaking up on another girl and pulling up her skirt. He was most likely kidding when he mentioned this.
YandereDev hopes to implement the ability to put custom skin and uniforms on students in the future.
In the future, students will be programmed to carry their book bags.
In the final game, it is almost certain that all students will be the same height.
Originally YandereDev stated that there would be at least one exchange student and that they would most likely be American so the student could be a comically exaggerated American stereotype.
However, YandereDev has since stated that he does not think he'll add an exchange student.
YandereDev has hinted that one of the current students may have multiple personality disorder.
If the S key is pressed in the debug menu, looking at the second reserved student slot displays a profile with an ‘Invincible’ self-defense, and the ‘Protective’ persona.
