Ian Kruger is the real name and identity of Roman.
Roman, his sister Alice Kruger and his parents lived in Pretoria. Both of his parents were anti-Apartheid activists and when they were killed, Ian and Alice were taken to a secret academy to be trained and become deadly soldiers.
During his time into the academy, he received a cut on his face by a boy with a razor blade.
Life inside the academy
Alice and Ian managed to hide a 1 Rand coin which it became their only possession from their old lives. The coin was used by the two children as present in birthdays and important dates. They usually kept it with themselves but when not, it was hidden away inside of a chewing gum wrap.
When the academy was shut down, the children were freed; Ian and Alice were found by Shepherd who decided to adopt them after realizing they were too dangerous to be put among people who couldn't control their behavior.
