Osana Najimi

'''Osana Najimi is the first introduced rival and a student at Akademi High. She will be used as a tutorial at the beginning of the full game. '''

YandereDev needs to complete very few key game features before implementing her into the game.

Original
Osana's original look was Raibaru Fumetsu's current appearance.

Osana had light orange eyes and golden-orange hair tied up in two short pigtails. Her hair was tied up in two pink scrunchies with white polka dots and she had a light purple bow on the right side of her head. She wore white leg warmers similar to the ones the bullies wear.

Current
Osana's current appearance has orange eyes and hair, which is tied into twin-tails that reach her knees. The ends of her hair fade into a small yellow gradient. She has a bust size of 1.To keep Osana's hair tied, there are thin salmon pink scrunchies with white polka dots. She also wears matching stockings. Her shoes are black and she wears a small red bow on the right side of her head.

As of the March 15th, 2018 Build, her hair and eyes are much lighter and her hair gradient starts further up. This appearance was mistakingly made available to players. As of the March 31st, 2018 Build, she has retained her lighter hair and eyes but slightly less saturated. YandereDev stated that this happened because he wanted to test out features.

Description
"Osana and Senpai have been close friends ever since they were very young children. They have always lived next-door to each other, and have always walked to school together.

Despite their closeness, Osana is quite rude and harsh towards Senpai; she is always easily irritated and quick to anger when he is around. The reason for this behavior is because Osana has developed romantic feelings for Senpai, but she is afraid of letting him know how she truly feels about him.

She doesn't want him to know how she really feels about him, so she is mean to him at almost every opportunity. However, her true desire is to confess her feelings to him underneath the cherry tree behind the school...and if nothing stops her, that day will come very soon."

Introductions
In the original introduction of the game, after Ayano Aishi bumps into Senpai, she can be seen talking to him, acting like a stereotypical tsundere. The first introduction can be seen on YandereDev's YouTube channel, but the introduction is now outdated.

In the second introduction added in the August 15th, 2015 Build, Osana is mentioned by Info-chan, as she requests for Ayano to murder Osana. Info-chan expresses that she wants Ayano to "make her suffer". It is currently unknown what grudge Info-chan holds against Osana.

The updated version of the second intro, added in the June 15th, 2019 build, is slightly different from the original second intro, but now features graphics. In this cutscene, Osana and Senpai are seen talking near one of the bathrooms. The Osana and Senpai talking animation loops, the surroundings are blacked out, and the animation is seen through the hollow in Ayano's silhouette. Ayano then expresses that she wants to kill or hurt Osana. During the Info-chan texting sequence, the dialogue was not changed and, according to the paragraph above this: "Info-chan expresses that she wants Ayano to 'make her suffer' It is currently unknown what grudge Info-chan holds against Osana."

Personality
Osana Najimi is a tsundere, meaning that she is hostile and cold towards someone she likes before warming up and becoming sweeter to a person eventually. She seems to be much nicer to girls and her other friends. Regardless of her rudeness and Senpai's ignorance, Osana is still very considerate.

Osana is implied to be a popular student, as she‘s seen sunbathing with 6 other girls and she herself says that many boys ask her out.

Background
Osana is an only child. YandereDev doesn't imagine her mother to be tsundere.

Osana and Senpai attended the same middle school. They have probably known each other over a decade.

Routine
Though it is unknown at the moment, YandereDev has said that her routine will put Osana in close proximity to Senpai or other students.

If Osana was put into the game via changing file names in the October 16th update, she would go to the roof, take a phone call, go to the roof, go to class 3-2, and stand there at the back for the rest of the day. She wouldn't take the phone call on Monday.

If she was put into the game via changing the file names in the November 15th update, she would stand in front of Senpai looking at the fountain, take a phone call, go back to the fountain, go to class 2-1, and sit down for the rest of the day.

As of the January 3rd, 2017 Build, it was no longer possible to add Osana into the game via the JSON folder. If the player attempted to add Osana, they will encounter Fun Girl instead.

As of the March 31st, 2018 Build, if added to the game, Osana will socialize with Raibaru Fumetsu every day and take a phone call on Monday.

As of the May 3rd, 2018 Build, if added to the game, she will socialize with Raibaru every day, and will not take her phone call, nor will she patrol clubrooms.

Osana has a crush on him but he is oblivious, as a result, she tries to impress him in the days leading up to her confession.

If Osana entered a relationship with Senpai she would give him "tough love" and would lecture him about leading a carefree life and would encourage him to pursue a career that involves one of his interests. This would eventually lead him to become an author or a horticulturalist.

If all the rivals were in school in the same week, Osana would probably end up with Senpai.
