Osoro Shidesu

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

Appearance
Osoro has unkempt, shoulder-length blonde hair and brown eyes. She wears a regular uniform with black shorts underneath, along with a large torn jacket hanging off her shoulders. She also has bandages on her muscular arms and legs as well as around her ankle. She has an 'X' shaped scar on her left cheek.

Osoro's appearance was first partially revealed in YandereDev's video, "October Update Preview". As of November 23rd, 2015, YandereDev has already designed the rival.

As seen in the first teaser, she wore a torn male uniform as a cape. She has bandages on her arms and an adhesive bandage on her right leg. She has spiky blonde hair with tufts on the top. Under her skirt were baggy navy blue pants that end above the knees. She wore ankle socks.

Description
"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?"

Personality
She will most likely have the delinquents' persona, making her unique among the rivals. If she witnesses murder, she will not run to Senpai, but will instead attack the player. She will not be an evil character, but she has been suspended from school for something gravely serious. She is the most dangerous girl in school.

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.

Senpai

 * Main Article: Senpai

As she will be a rival in the future, she will have a crush on Senpai. There will be a reason as to why she can win Senpai over even though she's a delinquent and will most likely have a low reputation. YandereDev will not spoil the reason on Twitter, but apparently the two will grow some sort of bond together.

Suitor

 * Main Article: Suitors

In the future, Yandere-chan will be able to matchmake the delinquent with her suitor.

Cronies
She has ten cronies in total: five females and five males.
 * Copper Streak
 * Dandy Pompadour
 * Josuke Pompadour
 * Lime Streak
 * Purple Streak
 * Red Streak
 * Spiky Pompadour
 * Tall Pompadour
 * Teal Streak
 * Triangle Pompadour

Trivia

 * Osoro can be killed by a mind-slave, but it is much more difficult than using a mind-slave to kill other rivals. If a mind-slave attacked Osoro, she would defend herself. However, while Osoro is defending herself, Yandere-chan will be able to sneak up from behind and stab her in the back. This would probably be enough to give the mind-slave the advantage and play out the normal "killed by mindslave" animation.
 * It will be harder to soak Osoro with a bucket, as she will have fast reflexes.
 * Her name is derived from the phrase "恐ろしいです" (osoroshīdesu), which means "terrifying".
