Osana Najimi

Osana Najimi (幼なじみ Osana Najimi) is the tsundere character in Yandere Simulator. She is the first introduced rival and is used as a tutorial at the beginning of the game.

Original
Osana's former appearance had the character model of Raibaru Fumetsu, another character in Yandere Simulator. Her old appearance had light orange eyes and golden hair tied into two fat pigtails. Her hair was tied up by two pink scrunchies with white polka dots and she had a light purple bow on the right side of her head. She wore loose white leg warmers.

Current
Osana's appearance was changed because she "didn't look tsundere enough". Her current appearance has orange eyes and hair, which is tied into long twintails that reach her knees. The ends of her hair fade into a small blonde gradient. She has an average bust size.

Osana's hair is tied up with 2 salmon pink scrunchies with white polka dots, and she has a small red bow on the right side of her head. She has black shoes, salmon pink stockings with white polka dots, and salmon pink panties.

Personality
Among the personas currently implemented, Osana is Lovestruck. If she witnesses a murder, she will run to Senpai and inform him that Ayano is the murderer, causing an automatic Game Over. Osana will not react to the player's phone camera aimed at her, instead becoming annoyed with Ayano and incurring a reputation penalty. Osana will only agree to follow Ayano under specific circumstances (if Raibaru is not hanging out with Osana and the player has a high reputation), suggesting that she doesn't trust others easily. Osana will also refuse to follow Ayano if the latter intimidates her as a delinquent. If Raibaru is missing or dead, Osana's walking animation will change and she will mourn her in the plaza before and after class.

Osana is based off the tsundere character trope found in Japanese anime and manga. She acts hostile and irritated towards Senpai to conceal her romantic feelings for him, although her true personality appears to be kind and friendly as she acts as such towards other students. She has a tendency to softly speak of her affections towards Senpai in between her aggressive outbursts towards him, and also frequently expresses her kinder side during her events with Senpai.

She is implied to be self-conscious and worrisome, as she often speaks to Raibaru on the topic of romantically pursuing Senpai, unsure of whether or not she has been too desperate or harsh with him. This is also shown during her matchmaking cutscenes: in certain dialogue options, she will tell her suitor that she is afraid of coming on too strongly, and is worried about her self image and what people may think of her hairstyle.

However, Osana will willingly follow the player if they have high reputation, even if Ayano has only spoken with her to complete her task. Although this behavior suggests that Osana easily believes her fellow students, it can be considered unusual that she exhibits gullibility despite her implications of issues with trust. For these same reasons, it is also unknown why Osana is able to become good friends with Raibaru in a relatively short span of time.

Osana appears to be a popular student due to her high reputation. She is close friends with Raibaru (another popular student) and is seen sunbathing with the Bullies, who are also highly popular girls at school. She states during her confession that many boys ask her out, suggesting that she is also considered attractive.
