In the Yandere Simulator game, Info-chan expresses a strong desire to see Osana suffer, indicating a deep-seated hatred towards her. It is also possible that Info-chan simply enjoys witnessing the suffering of others. The game features a total of eleven rivals, with some being fellow school members like Mida and Muja, while others belong to different classes. Osana, knowing that Senpai dislikes certain types of music, decides to create a pop music playlist for him to listen to during lunchtime on the rooftop. If Ayano turns off the alarm set for Osana, she will continue sleeping until 6:00 PM, and Senpai will become impatient and leave. If the book is not damaged, Osana tells Senpai that it was even more interesting than she initially thought, and they walk home together. In the event that her phone is not stolen, Senpai compliments the pictures on it, and they walk home together. Prior to Week 1, Osana and Senpai were close childhood friends, and they used to spend time together in the morning and during lunch every school day. Pressing 2 can change the day to Tuesday, while pressing R can alter the reputation rating.
When Ayano points a camera at Osana, she does not react, resulting in a loss of reputation points for Ayano. As part of the “Expulsion” elimination method, Ayano can frame Osana for vandalizing school property. Alternatively, after losing her friendship with Raibaru, Osana spends her free time walking around the school. Eventually, she runs to the Confession Tree and waits for either Senpai or Kyuji. It is during this time that she confesses her feelings to one of them. If Ayano sabotages the yellow vending machine and then buys chips from the red vending machine, Osana gets thirsty and attempts to get a soda. If Ayano fails to turn off the alarm, it will go off at 5:30 PM, prompting Osana to run downstairs to meet Senpai at the school gate. During lunch, she still eats with Senpai and cleans the fountain during cleaning time. As Yandere Simulator is still in development, it is currently free to download. Despite the game's unfinished state, it is visually impressive. Personas in the game determine how NPCs react when they witness a murder or come across a corpse. At 4:11 PM, Osana takes a nap on the rooftop to avoid falling asleep during a movie, with Raibaru sitting next to her to ensure no one disturbs her.
During conversations with other students, players can use the mouse to highlight dialogue options and press the E key to select them. I cherish this photo because it represents the dedication of a fan who created a doll based on Yandere Sim and the opportunity I had to collaborate with talented game developers. At 1:04 PM, Osana takes a picture of the east fountain, the same location used for the Matchmaking elimination method. At 5:21 PM, she shows the picture to Senpai. If Ayano recorded a conversation with Musume, she can steal Osana's phone and replace the music with audio that makes it sound like Osana is saying hurtful things about Senpai. Ayano can also save Osana's cat from a stalker, either befriending or betraying her in the process. There is a scene where Osana talks to her stalker on the phone. After realizing that her book is damaged, Osana sits on a bench near the fountain and has lunch with Raibaru until lunchtime is over.
At 7:30 AM, Osana receives a phone call from her stalker, followed by Raibaru asking if everything is alright. At 7:03 AM, Osana and Raibaru discuss Osana's upcoming date with Senpai and decide to talk about it on the rooftop after classes. However, Osana expresses that she is not yet ready to discuss her personal issues. Evidence of murder or witnesses to murder are indicated by an orange outline. While walking to school together, Osana and Senpai have a conversation about nightmares. At 1:00 PM, Senpai listens to Osana's playlist. After stretching, Osana continues reading or searches for Senpai's book in the water. This provides Ayano an opportunity to take the book and place it in the water while Osana's back is turned. Kyuji is Osana's preferred suitor, and players have the option to matchmake the two characters in the current demo. It is revealed that Osana used to write fan-fictions involving romance with boys from her favorite anime. If Osana's phone is not stolen, Senpai compliments her taste in music, and they have lunch together. While “most likely” having an “orange” trademark color, Osana's favorite shade is salmon or persimmon pink, as seen in her scrunchies and stockings.
