Osana Najimi is the first introduced rival[6] and a student at Akademi High. She will be used as a tutorial at the beginning of the game.[7]

She was going to be implemented within several months (as of January 11, 2016) according to Druelbozo.[8] YandereDev first needs dozens of male and female animations in order for Osana to be implemented.[9]

It should be noted that the character who stands under the cherry tree southwest of the plaza is Rival-chan. The original design for Osana had Rival-chan's appearance, but YandereDev thought she didn't look "tsundere" enough. There is now a new appearance for Osana. Rival-chan is the student with the original model, who is now considered a different character.[10]

Osana's original store-bought model was not active because YandereDev wanted to give her a different character model to make her more unique, but it was not compatible with all of the animations that were made for the female skeleton that the rest of the girls have. She couldn't be properly implemented unless a character rigger made a control rig for her and an animator used that rig to make a full set of animations for her, or YandereDev gave her the same character model and animation as all of the other female students.

The downside of giving her the same character model as all the other female students is that she will would look like a clone of Yandere-chan, but with different eyes, hair, and stockings. YandereDev could not find anyone to rig or animate her original model,[11] so it is possible that this will be the case. Even with the old model out of the way, it may be a while until Osana's new model is implemented, because YandereDev does not want her added without also putting in a whole bunch of Osana-specific "event" animations.[12]

Appearance

Original

Rival-chan near a tree

Original Osana.

Osana's original look had orange eyes and her hair in two golden orange pigtails. Osana's hair was tied up in two plump scrunchies and she had a purple bow on the right side of her head. She wore white leg warmers. This appearance was given to Rival-chan, a stand-in for Osana.

Current

Osana Gif

Osana's new model has long, orange twintails that reach her knees. The ends of her hair fade into a small yellow gradient. Her hair is tied up in thin pink scrunchies with white polka dots, and she wears salmon pink stockings with white polka dots. Her shoes will be black. She wears a small red bow on the right side of her head.[13] A quick glance of her back was shown in, "Dumpsters, Buckets, Bathing, and Electrocution in Yandere Simulator". The videos "Yandere Simulator: Past, Present and Future" and "Personalities and Photography in Yandere Simulator" also show that her appearance has been confirmed. 

A full body model of Osana was shown on YandereDev's livestream on January 17th, 2016. The photo was shown around 9:18:15.[14]

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."[15]

Scenes

Introductions

In the original introduction of the game, after Yandere-chan bumps into Senpai, she can be seen talking to him, acting like a stereotypical tsundere. The player can see the first intro on YandereDev's YouTube channel, but this is now very outdated.

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

In YandereDev's video, "Delinquents in Yandere Simulator", Osana makes a small cameo by carrying a trash bag to the incinerator.

Other

Osana had a small cameo in one of YandereDev's videos, "I Want My Senpai Back". She was the main antagonist of the video and stole Yandere-chan's Senpai. She was killed at the end of the video by being stabbed to death by Yandere-chan, around 37 times.

Osana has another cameo in another one of YandereDev's videos, "It's Beginning To Look A Lot Like Murder - A Yandere Simulator Christmas Carol". She appears briefly for the lines, "Senpai's bothersome childhood friend is flirting with him again... She wants him, but I'll never let him go!", "A shiny sharp axe and one glorious whack to eliminate Osana-chan!", and possibly, "Lots of blood and gore!"

Osana has since had multiple cameos in the videos "January Osana Progress Report - Part 1" and "January Osana Progress Report - Part 2", demonstrating the progress made by YandereDev to put her into the game.

Personality

Osana Najimi is a tsundere, meaning that she is hostile and cold towards someone before eventually warming up and becoming sweeter. It's not very likely that Senpai would know about her crush on him, as she repeatedly insults him and he seems oblivious. Regardless of Osana's rudeness and Senpai's ignorance, Osana is still very considerate. In the original intro, she is shown walking with Senpai to school.

The second intro gives no indication of her personality, but "I Want My Senpai Back" makes her look like a tsundere, so she is still likely to be a tsundere.

Osana may not be a good friend to Senpai, considering that if she is eliminated non-lethally and Senpai's sister, Hanako, dies, she will not go back and comfort him.[16]

Routine

Though it is unknown at the moment, YandereDev has said that her routine will put her in close proximity to Senpai or other students.[17]

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 is no longer possible to add Osana into the game via the Json folder. If the player attempts to add Osana, they will encounter Fun Girl instead.

Relationships

Senpai

Main Article: Senpai

They were childhood friends in the first intro. Osana, Senpai, and Hanako all played together when they were younger.[18] Osana has a crush on him, although he does not seem to be aware of it. The first opening shows Osana and Senpai together, and even walking to school with each other. Osana yells at Senpai, but they are still close.

There is no information about their relationship in the second intro. Osana still has a crush on him, though, and will still confess her love to him on Friday. However, if Hanako dies and Osana is eliminated peacefully, Osana will neglect Senpai.[16]

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 into becoming an author or a horticulturalist.[19]

Yandere-chan

Main Article: Yandere-chan

Osana Najimi is a target of Yandere-chan because she is a rival for Senpai's affections. In the first intro, Yandere-chan has qualms about killing others. She simply wants a love life and Osana is in the way, but Info-chan, a glory-hungry journalist, gives Yandere-chan the idea to kill Osana.

In the second intro, Yandere-chan already wants Osana out of the way by any means necessary. Info-chan just encourages her more and tells her about Osana's plan to confess to Senpai.

In the "It's Beginning To Look A Lot Like Murder" video, Yandere-chan mentions that Osana is "flirting" with Senpai "again". This may indicate that Osana's tsundere demeanor is a way of flirting with Senpai, but it's also possible that this is just how Yandere-chan interprets her actions.

Info-chan

Main Article: Info-chan

In the first opening, Info-chan didn't hold anything truly personal against Osana. However, she was once the main antagonist and was going to be a rival for Senpai.[20] The original intro also shows that Info-chan wanted some terrible events to unfold at Akademi High to boost her newspaper sales. Her motive for wanting Osana dead might have been one of the two, or both reasons, depending on when Info-chan being the main antagonist was changed.

The second intro does not state why Info-chan is going against Osana. Info-chan simply wants Osana to suffer, and anything about being a journalist is never stated. There isn't even a Newspaper Club at Akademi High anymore,[21] which makes it unlikely that her motive is wanting her articles to be popular.

Hanako Yamada

Main Article: Hanako Yamada

Osana, Senpai, and Hanako played together as children.[18] Osana might be the only person that Hanako would be willing to "give" Senpai to. Hanako wouldn't really look at Osana as competition, or a threat, or an enemy. Hanako would be very sad if Osana died.[22]

Suitor

Main Article: Suitors

In the future, Yandere-chan can matchmake Osana with her suitor.

Trivia

  • Osana Najimi's name is a pun on osananajimi (幼なじみ), a common trope in the romance genre which means "childhood friend" in English.
  • In the final game, Osana may tease Senpai about how he stands under the cherry blossoms all day, a reference to how long Rival-chan was under the cherry tree.[23]
  • YandereDev said on Twitter that Osana's birthday will be in January, most likely the 1st.[24]
  • Osana will perform the same "hip sway" animation as "Sansdere-chan" from Bad Time Mode.[25]
    • The animation can be found with the name "TsunIdle".
  • She is the second tsundere character to be introduced by YandereDev, the first being Tsundere-chan from Kuudere Simulator. YandereDev has said that Osana Najimi is "Tsundere-chan with an actual design that had effort put into it." [26]
  • At one point, YandereDev considered splitting Osana into two characters - a gentle childhood friend with Rival-chan's appearance, and a tsundere childhood friend. They wouldn't have been sisters, however, as that would mean eliminating one might affect the other so strongly that she couldn't consider dating.[27]
  • Her voice actress, Brittany Lauda, plays another tsundere named Audrey from the popular adult game HuniePop.
    • Brittany Lauda was once asked to record more lines for a Senpai-Rival interaction event.[28]
  • Osana's design was inspired by anime characters such as Asuka Langley Sohryu from Neon Genesis Evangelion, Rin Tosaka from Fate/stay night, and her twintails and stockings were inspired by Michiru Matsushima from The Fruit of Grisaia.[29]
  • YandereDev had stated that in a few months, Osana will be added to the game to test out elimination methods that can only be used on "real" rivals.
  • YandereDev said that the fastest possible way to put Osana into the game would be to take all of the code that applies to Kokona and point it at Osana.[30]
  • In the October 16th update, it is possible to add Osana into the game by changing ID 33's name from "Unknown" to random words in the JSON file.
    • As of the January 3rd, 2017 Build, it is no longer possible to add Osana by editing the ID 33's in JSON files. Attempting to do so will trigger an Easter egg involving Fun Girl.
  • Osana is an only child.[31]
