Yuri was the only child of the Head of Spider Yakov, Yakov was considered the greatest Head of Spider, he led The Spider to glory.
It was in his hands That the Spider become the biggest and the most feared syndicate in UG, with his leadership they exterminated all rival gangs and organizations that opposed them.
They bribed and threaten many government officials in Central City, which many are afraid to do, as HFA has a very tight relationship with UG among any other nation on earth, but The Spider was able to do it under the nose of HFA and under Yakov leadership, hailing him as the greatest Head of The Spider, Yakov has everything he needed except a son, his wife died of childbirth to a daughter.
Yakov loves his wife very much, so much so that he has never been with another woman besides his wife. But when Yuri is born he never hated or despised her, in fact, he was very worried about her future for no woman is allowed to take the seat of Head of The Spider, so to protect her daughter he killed everyone who knows of her identity and picks two of the most outstanding protector candidate as her protector.
He raised her as a boy, and repeatedly told her not to reveal her true identity to anyone under no circumstances, he told her that her life will depend on her keeping her identity.
Yuri was a smart girl, in fact, she was very outstanding at the age of 14 she is already very involved in The Spider management her father let her manage and give her open authority in many decision-making. The Spider and the Elders and Leaders respect her so, in fact, she's been acting as the Head 5 years before her father officially hand her the position of the Head of The Spider.
It's very easy for her to disguise herself as a man using a voice-changing tech. An oversized coat to hide her body, she even wears a mask to hide her feminine face. And no one ever questions her, everyone feared her more than they respected her and in a criminal organization fear is a very powerful weapon, and she knows this because her father repeatedly told her so.
So when a group of Elders and Leaders tried to instigate a coup she didn't just capture the traitors, she also captured everyone close to them and put them in "Hell" The Spider's most feared prison. [Hell] was created specifically for Traitors and offenders as well as enemies of The Spiders
That action solidifies her position as Head of The Spider no one else will try or even think of questioning her decision, for on that day she butchers more than a thousand traitors and imprisoned hundreds more, oftentimes she forgets she was actually a woman for all her life she acted like a man, and not once she shows any weakness that would make others suspected her otherwise.
Yuri never once shows fear in the face of her enemies not even when the rebellion happens not even when she was cornered and outnumbered she shows any fear, but now in front of the two girls, she felt something she never felt in a long time Fear and Desperation not even when her most beloved father died he felt this afraid and desperate not even when the coup happen she never felt this afraid, even when she was surrounded by the Shadow Units she never really felt afraid, she didn't think, not even once that her life is in danger.
She was surprised when she saw Mikhail being captured, but even then she was never really afraid. Only when the two girls appeared in front of her, she realized her life is no longer in her hands...
The Spider has one more trump card that only when the existence of the Spider is in danger can this trump card be played, but how come she felt that even if she's used that trump card nothing would change in front of these two girls all schemes are useless, in fact, it wasn't just the Head who felt like this Mikasa as well as everyone, Elders who have been enhanced and been through a lot also felt this way…
"Impossible, what are you two..." Beru said as he points his finger at Ruby and Jem while shaking
"Well, we can be your executioner or your new Boss, depends on how you act in a few minutes." Said Jem to Beru while grinning
"You have 30 seconds to decide to become part of us. Or, well, part of them." Ruby said she points at the dead officers
... for ten seconds no one spoke until one of the officers kneel down and said "ill join you"
After that one by one many Officer follows, 20 seconds later almost all officers are kneeling but no leader or elders submitted.
"After ten seconds, kill everyone who doesn't submit." Ordered Ruby while releasing a boundless killing intent.
Only now they found out how serious the other party was when they gave the ultimatum, most of them believe that there's no way they will kill them all just because they said so, the fact they were still alive proves that their enemies don't want them dead and want something from them and wouldn't really kill them.
In that case, they can still negotiate, how wrong they are for Arc very much wants to kill them all and the 30 seconds were given to them as a second chance Ruby, Jem, and the rest of the Shadow unit know this, so when Ruby release her killing intent all shadow units follow they are really going to kill them all...
Soon one of the leaders couldn't resist the pressure anymore and kneeled Leaders follows and when only 5 seconds have left some elders also kneeled and 2 seconds before the time limit Beru kneeled, he was trembling and shaking as he kneeled…
"Times up kill the rest, leave the Head and the girl beside her, cut off her limbs if she resists." Said Ruby without any emotions on her face.
