Tapes

'''Collecting and finding tapes is an implemented feature in Yandere Simulator. They are used for listening to recordings of people about their past that we would not know of otherwise while playing the game.'''

In YandereDev's August 1st Build Delay video, he provided previews of the new features available in the next build. One of the slideshow of features are tapes. There are 10 tapes in total, hidden around the school. On your Phone, there is a wifi signal on the top right corner that can signify whether you are close to a tape or not. If there are parts of the story that can't be revealed by normal gameplay, more cassette tapes will be added. In the August 12th build, the tapes were implemented. The tapes can be played in the cassette player in the Computer Lab. Use the Left and Right arrow keys to rewind and fast forward, 'E' to pause, and 'Q' to stop the tape from playing.

They are told from the point of view of an unnamed journalist, which reveals a backstory. The journalist's daughter's identity has not yet been confirmed. However, the person's identity will be extremely obvious in the final game.

Trivia

 * The Headmaster is mentioned for the first time in Mysterious Tape 2.
 * The tapes reveal that there is an active Yandere-woman living in Yandere-chan's town. It is unknown whether she is currently in Japan, or she may have left the country to hunt the Journalist down.
 * Instead of tapes, there used to be an original plan where Yandere-chan would learn about the murders through scattered newspaper articles.
 * There is a planned tape to explain why Info-chan is in a one member Club that is exempt from School Rules as soon as an appropriate voice actor is found.
