It was partially implemented in the October 8th, 2015 Build, and fully added in the November 1st, 2015 Build.
It is located on top of the panty drawer in Ayano's bedroom. Ayano is not able to interact with it during the day. At night time however, the player can walk up to the shelf and a small HUD will appear saying "Read Manga".
Each volume increases Ayano's skill by one level, but the same volume cannot be read twice. In addition, when the player reads manga, Ayano will arrive at school one hour late. Before Ayano reads, the menu asks if the player would like to arrive late. Press E to accept and Q to decline.
The player will wake up at 7:30 AM. Since they are already one hour late, they cannot torture a prisoner for an hour in the basement, but can still do so for 12 or 18 hours. If the player decides to go to school, they will arrive at 8:00 AM.
In the future, there might be five sets of manga that have effects on gameplay while one set of manga is for Easter Eggs,and another set would relate to a game YandereDev made before Yandere Simulator.
Currently, the manga novels that are in game are:
- Cherry Touch (increases Seduction level.)
- Life Note (increases Enlightenment level.)
- Yokai Story (increases Numbness level.)
Bukiyona-chan's Daily Life
In the future, the player may be able to read a comical manga series about a very clumsy girl in order to figure out how to "accidentally" douse a student with a bucket. This series may have been inspired by the ero guro manga of a similar name, "Mai-chan's Daily Life," which also focuses on a female protagonist who is also extremely clumsy.
- There may be a manga series called Magical Girl Miyuki, a popular magical girl manga in-game. If Ayano collects all 10 manga, then the player is able to unlock a magical girl Easter Egg.
- Manga may work differently in the final version: it may take five nights to read one book, but reading won't make the protagonist late.
- If Yandere-kun is ever implemented, a gender-swapped version of Cherry Touch will need to be created. If implemented, then Seduction would initially work on girls, before finally working on boys at level 5.
- YandereDev is open to the idea of fan-comics of Yandere Simulator, but they'd have to be at the level of the fan-comic, "Fall Girl". To include "Fall Girl" in the game, however, YandereDev would have to have the author's permission.
- Although Ayano buys manga, she does not enjoy them. She only reads them to make herself look like a normal school girl.
- Manga has no outline in Yandere Vision. However, the signal bars on Ayano's phone indicate how close Ayano is to a volume.
- In the future, it may be possible to read a horror manga so Ayano can learn new methods to kill with.
- If the player presses S while at the manga menu, Ayano's Seduction, Numbness and Enlightenment levels will increase. While at school, the player can press \ for the debug controls and then S to max out their Seduction level.
- The manga covers were illustrated by Yessenia Taylor (Mulberry).
- The game's warning referred to manga, saying that this game contained "lewd manga". This warning was later removed because YandereDev said that it was "cringey".
- 'Bukiyona-chan's Daily Life' may not make it to the final game due to the tripping feature being removed.
- Cherry Touch and Yokai Story were deposited and located in random places in the school, up until the October 22, 2019 Build.
