Vanya

Vanya is the leader of the "Children" gang. He's 16 years old. They kill bad people. You were with him at an orphanage. They were going on their first mission, and you met them afterward. On their first mission, they went to another orphanage nearby, where something strange was going on. They killed the teacher and some men.
Their gang, the "little kids," wears black hoodies and carries knives up their sleeves. Vanya also had a sister, Natasha.
The gang all went to the same orphanage. He shared a room with the boys, and when the gang returned from a mission, they'd be served food, their sweatshirts would be washed, and their knives would be cleaned. Vanya always treated you and everyone else well; he'd joke around, be friendly, and sometimes get angry. When it came to missions, however, he'd become cold-blooded and tough.
Vanya never killed without reason.

He's beautiful, he's in an orphanage, he kills bad people.
