In the game Yandere Simulator, the main character Ayano and Info-chan do not mention anything about Osana's death. The developer, YandereDev, has discussed the potential implementation of a sanity meter for the character Senpai in the future. YandereDev also mentioned that he would like Senpai to be slightly taller and has considered releasing Senpai's textures for players to create custom skins. To play the game, you need to unpack and run the YanSimJuly22nd.exe file. By default, the game downloads to the same folder where the launcher is located.
Yanvania: Senpai of the Night is a video game that players can play in the bedroom. In this game, there is an innocent-looking girl with a criminal mind, and many of the deaths can appear as tragic accidents.
The title “多朗” written in Kanji can mean “many shiny.” Senpai's default appearance is designed to resemble a generic male anime protagonist. While Ayano is a member of the club, she automatically wins any wrestling minigame against other students and teachers. However, losing is still possible if Ayano doesn't have a concealable weapon. It is important to note that this feature is still under development.
Senpai accepts the confession of any rival with a good enough reputation, unless Ayano sabotages his relationship with them. This indicates that he is still fairly meek. Some popular people may take notice of him. Senpai enjoys nature more than the company of people and is considered a loner.
Oka is a fellow student who has a crush on Senpai. He is the same height as other male students in the game to ensure animation compatibility. The school's Audiovisual Room contains a radio. You can take pictures of it and modify the uniform in the sewing room to get the correct uniform. Senpai wears the default school uniform with gold buttons and black cloth, although players can change his outfits.
Senpai's default appearance includes light skin, charcoal grey eyes, and short dark hair. Players have the option to customize his appearance at the beginning of the game, including skin tone, hairstyle, hair color, eye color, eyewear, and facial hair. If no changes are made, Senpai will appear with his default look.
Senpai's sanity will decrease more if Osana or Hanako Yamada dies. If the player damages his book, Senpai will be angry at Osana for breaking her promise and will walk home alone. However, the teacher will discover the evidence at the end of the day as usual.
Oka asks Senpai about his favorite book, which was a gift from his sister. Senpai lends it to Osana for the rest of the day, but only if she promises to take good care of it. At 5:29 PM, Senpai meets Osana at the front gates to retrieve his book.
Players have the ability to leave the club with permission, but they can never rejoin once they leave. If Ayano approaches Oka too closely, she will push her away with a graceful spin. In the official game, players will be able to choose Senpai's gender.
Senpai has a younger sister, and Ryoba is Journalist's sister, although they pretend not to know each other. During lunchtime, Osana goes to the plaza to read Senpai's book at the fountain, just like he does. Osana also asks Senpai about his favorite place in the school, and he mentions that the plaza is the most soothing place he knows.
In the official intro of the game, Senpai is seen bumping into Ayano and helping her up, portraying him as kind and considerate. However, in the second intro, Senpai's character is not as developed as in the first intro.
In summary, Osana's death in Yandere Simulator is a mystery, and the game offers various customization options for Senpai and his surroundings. Senpai is portrayed as a meek loner who enjoys nature and has a younger sister.
