Osoro Shidesu Gallery Illustrations Quotes [[:Osoro Shidesu/|]]

Osoro Shidesu is the eighth upcoming rival and the leader of the delinquents in Yandere Simulator.

Appearance

Osoro has unkempt, shoulder-length blonde hair and brown eyes. She has an 'X' shaped scar on her left cheek. Her bust size is 1.3. Osoro's messy hair is a result of meticulously combing her hair to make it presentable, with her pet flying on top of her head and ruffling her hair, appearing messy before she leaves her home.^[3]

Osoro is the second tallest girl in Akademi^[4] at 165cm (5'5").^[5] She is one of the heaviest students at Akademi, as the weight is from muscle,^[6] also being described as "extremely muscular".^[4] In her official art, she is shown to have a muscular figure, with well-defined arms and legs.

She wears the same school uniform as the other girls with black shorts underneath her skirt, a large, torn jacket hanging off her shoulders, and bandages on her arms and legs unless customized by the player. Outside school, Osoro wears something similar to what the woman on the left in this photo wears and never takes off her "cape".^[7]

Personality

Osoro is the leader of the school's gang of delinquents. Very little is known about her past, or her goals. She has been known to be violent, so most people tend to stay away from her out of fear.

Osoro will be absent from school for a very long time, and will not make her appearance until the eighth week of gameplay. Against all odds, she will develop a bond with Senpai, who normally keeps his distance from people like Osoro.

Senpai and Osoro are polar opposites — so, what kind of experience could possibly cause them to form a friendship? What does Senpai know about her? What does he see inside of her? And what could stop their friendship from blossoming into something deeper?

— Description on the official website.

Gameplay-wise, like all other rivals, Osoro will be Lovestruck;^[8] however, if she witnesses Ayano Aishi committing murder, she will not run to Taro Yamada, but will attack Ayano instead.^[9] She is the most dangerous girl in Akademi besides Ayano.^[10] In case of a direct attack from a mind-slave or Ayano, Osoro would react similarly to Raibaru Fumetsu.^[11] Attempting to take a panty shot would result in the same reaction.^[12] It will also be more difficult to soak Osoro with a bucket, as she will have fast reflexes.^[13]

Overall, Osoro can be described as a closed-off and aloof, yet hardworking with a hidden softer side.^[14] She appears to have extremely low trust in other people, with only a few exceptions, and isn't willing to accept any offers or help from anyone.^[15] Despite the way she's trying to portray herself and how most people see her, Osoro appears to see violence only as a way of defending herself or others, and isn't actively seeking out to harm other people in any way; she may intervene in situations like bullying, however, only to eliminate the immediate threat and not to comfort or otherwise help the victim.

Osoro dislikes speaking unless necessary and often refuses to respond to people speaking directly to her, as her intimidating aura is often enough to make someone stop what they are doing and defuse most situations, without her even saying a word. If she does respond to someone, she's probably going to be terse and may use profanity. If someone tried to have a positive interaction with her, she wouldn't deliberately be rude, but she wouldn't be polite either; her response would indicate that she doesn't understand how to express herself or respond meaningfully to people who are trying to interact with her, even when they're being nice.^[16] This doesn't change depending on whether or not she's comfortable with the people present, as she speaks the same way with the rest of the delinquents. Osoro also rarely openly expresses her emotions; she remembers the last time she cried, but she hasn't cried for several years.^[17] The last time Osoro cried was around the age of 10. That was when she decided, since nobody in this world would help her to survive, she had to become somebody strong, and that meant she couldn't allow herself to cry. ^[18] YandereDev imagined that if Osoro had one friend, that same person would be her best friend by default. This is because Osoro views herself as a person with no friends.^[19]

The reason Osoro will appear only in the eighth week is that she has been suspended from Akademi for one week seven times in a row.^[20] The reason for that is that Genka Kunahito and Kocho Shuyona were able to reach an agreement: the Faculty and Student Council will tolerate the delinquents' behavior for 10 weeks, and give the counselor a chance to reform them. However, if Genka is unable to reform the delinquents within 10 weeks, she will be dismissed from Akademi and the delinquents themselves will be expelled. Genka recognized that it would be difficult to reform the delinquents while their biggest influence — Osoro — was still present at school. The next time Osoro slipped up, the counselor expelled her for 7 weeks.^[21] YandereDev always imagined the suspension reason as something like "threatening a teacher."^[22]

Nobody is willing to bully Osoro. She is tall, muscular, and physically frightening, and her presence is imposing. If someone were "stupid enough" to bully her, she wouldn't respond or even acknowledge them. If they tried to touch her, she could punch them hard enough to break any bone in their body, if she wanted to.^[4] Despite her intimidating behavior and aura, she does not have any interest in joining a gang.^[23] If Osoro saw the bullies bullying another student, she would hang around and give off an intimidating aura, and that would make the bullies too scared to do anything with her around.^[24]

She doesn't back down from a fight that someone else starts, but she also doesn't go out of her way to start fights, either.^[16] If someone would challenge her to a fight, she would not verbally accept the challenge, but would not decline, either. She wouldn't say anything at all; without changing her posture, she would simply stare her opponent in the eye, silently. If her opponent drew closer, she would tilt her arms back to make her coat fall from her shoulders. If her opponent continued to draw closer, she would angle her body to make it easier for her to react to an attack; not a full-on "fighting stance", but a "ready stance". If, at this point, her opponent threw out an attack, only then would she make any type of aggressive move. Her specialty is deflecting her opponent's first move and ending fights with a single knockout blow, landing a punch on the opponent's chin that makes their head turn so quickly that their brain slams against the interior of their skull at high speed, and they go unconscious immediately. If their opponent doesn't go down from a single punch, Osoro fights very, very dirty, without mercy, going for eyes and other sensitive areas. She prefers not to speak at all unless it is to return an opponent's taunt with an unexpected, witty comeback in a completely flat tone of voice.^[25]

Osoro's fighting style is best described as street fighting, as her goal is to quickly stop her opponent with brute efficiency, even with no structure or plan to incapacitate them. This may include using nearby objects as weapons and using dirty tricks (such as aiming for a vulnerable spot in the human anatomy or using her teeth) to ensure she wins. Osoro does not care if she has any visible injury marks when the fight is over, which is often why she has many scars on her body.^[26]

Background

Currently, not much is known about her background, as it will play an important role during her week, and a lot of it would be spoilers. However, the revealed details point towards a very difficult, if not traumatic childhood.

Osoro's exact relationships with her family are unknown, but her father is stated to be neglectful, refusing to buy even proper food for his daughter, potentially abusive, an alcoholic,^[27] and someone who smokes.^[28] He does not show affection or love to his daughter, which results in Osoro always wondering what it feels like to be hugged.^[29] Her X-shaped scar is a result of a "drunken family member" who beat her with a broken bottle.^[30] Osoro was also made fun of by other children for several reasons as a young child. Some of these reasons included "coming to school covered in bandages or with new scars, and being poor". Her relationship with her mother is completely unknown, as it would be spoilers;^[31] the only known fact is that her mother died during childbirth,^[29] and her family overall will be an important aspect of her week.^[32] In her early childhood, she had toys, but they started to slowly be taken away in the middle stage, up until her "late childhood".^[33] She has never celebrated her birthday due to the circumstances of her life.^[34]

Osoro's extreme distrust towards people and closed-off nature appear to come from negative experiences during childhood; she attempted to befriend other kids, but it never worked. But because intimidating other kids changed this, it made them too afraid to make fun of Osoro. She decided then to be scary and frightening rather than try and attempt to make friends.^[35] This resulted in her not wanting friends.^[36] Despite her unwillingness to be around people, Osoro has "fans" who find her attractive, cool,^[27] and hot.^[3] Due to her trauma, a hypothetical situation of Osoro being hugged would result in her panicking and pushing the person away, as she would need a lot of time before feeling comfortable hugging someone.^[37]

Growing up and still living in poverty, she had earned the money to pay the Akademi tuition fee, starting to work as soon as she turned 15.^[38] The exact reason why she chose to do this instead of using the money to get out of poverty would be a spoiler, however, she does have some huge reason to enroll in Akademi in the first place and not let herself be expelled, having to swallow her pride and be respectful or cooperative to others when she normally isn't.^[39] Her father refuses to buy anything more expensive than the cheapest kind of food, so she had to learn how to cook and buy her ingredients on a very low budget, saving for the tuition fee. She isn't an expert, but her food is better than the alternative, and she appreciates the topic of cooking.^[40] Osoro would not accept anything offered to her; however, it is hard to tell whether it is because of pride or distrust towards other people.^[41] It is, however, explicitly stated that she's ashamed of her living conditions, explaining why she doesn't turn on her web camera during class.^[42]

Routine

Though it is unknown at the moment, YandereDev has said that her routine will put her near Taro or other students.^[43]

During class time between Week 1 and 7, Osoro will attend her classes via a SAIKOU laptop on her desk.

Topics

The topics Osoro is Negative/Positive/Neutral towards are as follows:

Positive	Negative

Cooking Music Martial Arts Cats Money	Drama Violence Reading School Family

Miscellaneous

Besides gameplay-related, her preferences include:

Favorite color: Black.^[44]
Video, TV shows, social media content: None. Osoro is least likely to have social media,^[45] and she does not watch TV or videos as much to have defined preferences.^[46]
Favorite food: Any food that involves protein, since it supports her muscle growth.^[47] Besides that, she enjoys grilled chicken, although she rarely gets the chance to have it.^[48]
- She also has had trouble finding a protein bar or shake that she enjoys the taste of.^[47]
Favorite song genre: Heavy metal, which gets her pumped up when she goes jogging or is at the gym.^[49]

Relationships

Taro Yamada

Main article: Taro Yamada

Like most other rivals, Osoro will have a crush on Taro. There will be a reason as to why she can win him over even though she is a delinquent and has a low reputation. YandereDev will not spoil anything, but apparently, the two will grow some sort of mutual bond.

Delinquents

Main article: Delinquents

Being victims of bullying and almost brought to the verge of suicide, the first time they met Osoro was when she was challenged to a fight by a rival gang of ten people right at the school gates — and managed to single-handedly defeat them all. This became a symbol that even a single person could defend and stand up for themselves; they started idealizing her and trying to copy her in every possible way. Due to Osoro's closed-off and distrusting nature, however, it took them some time to get on good terms with her — the radio they listen to every day is a physical symbol of their first steps towards it, as they had fixed and presented it to Osoro after she broke it after being confronted by Aoi Ryugoku who was following a noise complaint.^[50] Their relationship was fully established when they scarred their own faces^[51] and recolored their hair.

The training she provides includes not only physical or combat training, but also general advice and guidance; even though she always speaks curtly and vaguely, they learned to "decipher" her statements.^[52] In case of losing a fight with Ayano, their first thought would be to ask Osoro about the situation.

Osoro does not seem to express any care or affection towards them directly, but it is evident that she not only agrees to train and mentor them but also tolerates and protects them even when it may lead to getting in trouble herself.^[52] She looks at the other delinquents the same way as one another, but acknowledges that Umeji Kizuguchi has better leadership qualities and trusts him to lead the delinquents while she is absent, as her right-hand man.^[53] Additionally, she would also find Umeji the easiest to be friends with.^[54] The only other delinquent that Osoro also feels about is Hayanari Tsumeato, since his smoking makes her dislike it due to it being a reminder of her father.^[28]

Shisuta Town Gang

Osoro has a long-lasting conflict with another gang from Shisuta town, as it holds a grudge against her for defeating their leader and stealing his cape, as they appear to believe, using "underhanded methods".^[55] Unlike her company, the gang does have an actual hierarchy system, which motivates its members to continuously try to fight her, albeit unsuccessfully so far.^[52]

Their first fight happened right after Osoro enrolled in Akademi; she humiliated their leader so badly that he showed up with nine other people to "teach her a lesson" on ceremony day. Despite having an advantage in their sheer number, they lost the fight, and she took the cape from the leader, laying the foundation for her reputation at school, the heated relationship with them, and unknowingly stopping the five bullying victims from taking an irreversible decision.^[56] YandereDev imagines that the reason for their feud is that Osoro walked through their group that took up the middle of the sidewalk, stepping on the leader's shoe while doing so. When he calls her out, she calls him an "asshole," and he tries to grab her, to which Osoro reacts by punching him, fracturing his nose. This caused the leader to feel humiliated that a random girl just humiliated him in front of his goons, going as far as to craft a plan to try and surprise attack her at Akademi.^[57]

The exact number of times they had encountered each other is unknown, but there was at least one that was described. A few of the thugs from this gang showed up in the morning at the school gates again, intending to defeat her and take the cape back. While Osoro herself did not want to engage in further conflict or fight them, she had no other choice, as Hayanari provoked them, putting himself in danger. The fight ended without even starting properly, as Osoro broke one of the guy's noses, and neither she nor Hayanari got any significant injuries; however, she had expressed that she wasn't really satisfied with how the situation turned out, and it could've been a better choice to just give them the coat instead.^[52]

Even though Osoro isn't present at school during the first 7 weeks, on the second week, Sakyu Basu explains to her sister that Kyoshi Tachikawa, the physical education teacher, is watching the school gates because "there's a gang of delinquents at another school who plans to come here and beat up one of our students".

Pet Bird

She has a pet cockatiel^[58] who YandereDev imagines as a male. Her father doesn't like the bird, so the animal cannot leave Osoro's room. She is the only person who takes care of her pet in her household.^[59] She inherited her pet after the original owner at the place she worked at (being a humble cashier at a bookstore in another town)^[60] passed away.^[61] Although her father would try to take care of the bird (as he would be devastated if she died), he could get frustrated and release it.^[62]

Others

Students and Rivals: Osoro feels indifferent towards other rivals and almost everyone else; she does not spend time thinking about the people who cross her path.
- All other people, with a few exceptions, including Asu Rito and Muja Kina, are afraid of her and wouldn't try to talk to her. Muja may get worried if she sees her bandages, but wouldn't try to ask anyway, afraid of getting yelled at.^[63]^[64]
  - Out of all rivals, Osoro would most likely talk to Mida Rana or Megami Saikou, as they both are authority figures. Osoro would feel obliged to cooperate with them and show respect, although still giving her usual short, one-word answers.^[65]
  - Additionally, Osoro would only get along with Megami if they had to beat up a gang of delinquents who approached Akademi intending to cause trouble.^[27] They share common traits, including that both women are serious, stoic, non-emotional, and keep their cool when facing problems. A conversation between the two would be similar to a person talking to their own reflection in a mirror. The only difference is that Osoro speaks in short and sharp sentences, while Megami speaks in long, eloquent sentences. YandereDev mentioned it may be silly, but these two women would understand one another and speak in short sentences as a way to communicate with one another. These "conversations" would be through contact and body language.^[3] While they do not know about each other enough, Osoro only knows that Megami appears cold and is the president of the Student Council.^[66]
  - Osoro and Oka Ruto being friends would be a "cute mental image" for YandereDev, but he is unsure how their friendship would've formed.^[67]
Raibaru Fumetsu: Raibaru is one of the few students who may not perceive her as dangerous or intimidating; however, if Raibaru attempted to test her theory by having a casual conversation with her, Osoro wouldn't respond at all, resulting in a very awkward and short one-sided "dialogue".^[68]
Budo Masuta: Budo knows she's a gang leader and is suspicious of her; however, in their hypothetical encounter, neither is depicted acting outright hostile towards the other.^[69] If Osoro wanted to join the Martial Arts Club, he would question whether she intended to use martial arts for good or evil. Budo would only let her join if he felt that her intentions were not malicious.^[70] Another hypothetical encounter between them is if they were assigned partners for class work. Osoro would diligently work on her part of the assignment, although a lack of communication could cause issues between the two. Budo would also have worries working with her, but he does his best to give her the benefit of the doubt and not judge her too quickly.^[71]
Itachi Zametora: If Osoro fought with Itachi, it would be one of the most "evenly-matched" fights in Akademi. Itachi would refuse to fight Osoro seriously at the start of the match unless he received several damaging blows. After that, he would fight Osoro as if he were fighting a man. Osoro would sustain injuries during the fight. In the end, Itachi's arrogance would cause Osoro to win. He would complain about her fighting dirty instead of fairly, but would concede anyway.^[72]^[73]
- In a hypothetical scenario where she bumps into Itachi while going through the school hallways, he is shown to be more openly aggressive. However, the situation doesn't erupt into a fight, as Osoro decides it would be "a waste of time and energy" and continues on her way, and Itachi does the same.^[69]
Kokoro Momoiro: In a hypothetical scenario where Kokoro would have enough courage to leave the bullies and join the delinquents instead, Osoro wouldn't turn down her request, but only if the rest of the delinquents would be comfortable with it. Kokoro, in turn, would act extremely politely and nervously.^[74]
Ayano Aishi: There may be a chance for Ayano to meet Osoro as early as Week 1 if she joins the delinquents, since the latter visits Osoro after school. YandereDev says it's a "plot problem" that makes him unsure what to do about it.^[75] Osoro would be concerned for Ayano, as it would mean she is facing bullying and needs protection.^[76]
Kiyoko Tatsuhara: The unknown sibling mentioned in Kiyoko's description avaliable on Reddit was originally meant to be Osoro, but was later abandoned by YandereDev.^[77] It's unknown what's their relationship now.

Trivia

Osoro itself is not a proper name. It is likely derived from the Japanese word Osoroshii (written 恐ろしい), which means "frightening" or "terrifying".
- Another possibility is that her name is from the Basque word Osor, meaning "fear" or "dread".^[78]
- Shidesu is not a proper surname.
Her surname comes from her mother.^[79]
After Megami Saikou, she is YandereDev's second favorite rival.^[80]
She would probably win in a one-on-one fight with Megami.^[81]
- Osoro would defeat Shiromi 9/10 times if Shiromi doesn't use any dirty tricks.^[82]
In an email, YandereDev answered that if Osoro wasn't in Japan, she'd be in South Korea.^[83]^[84]
In a situation where Osoro's life is at risk, and she has to kill people to not die, she would be in third place in terms of being a lethal risk, followed by Budo Masuta, Raibaru Fumetsu, Itachi Zametora, and Daisaku Aragaki.^[85]
Osoro could've been picked as an "enforcer" as a student council member by Megami Saikou because of her physical strength, but her role as a delinquent would disqualify her.^[86]
Osoro is physically capable of doing a backflip, but it will not be needed during gameplay.^[70]
Initially, out of all of the 202X rivals, Osoro ranked #10 in academic knowledge.^[87] However, this was later changed; the fact that it took Hanako Yamada multiple attempts to be able to pass the Akademi exams places Osoro at 9th place.^[88] In terms of intelligence and general knowledge, her rank might be slightly different.^[87]
She would not be expelled from Akademi along with other delinquents if they were expelled during her week.^[89]
Osoro does not drink alcohol.^[90]
Osoro may be applying a cinnamon scent, mainly because while she isn't the type to use perfume, she applies a scent to avoid smelling like "bird" or alcohol.^[27]
Osoro does not have a criminal record.^[91]
If Osoro had an iPhone, she would have the fifth-latest model.^[92]
Though it is revealed that she has never celebrated her birthday, this does not mean that she doesn't know her own birthday because every character of this game that YandereDev knows are aware of their own birthday.^[93]
