Kain

Kain is a boy about the same age as Orba, who came to the detention facility when he was fifteen, and took after him. He wasn’t that great physically or with a sword, but he excelled in dexterity, especially when handling handguns or rifles.

He was arrested along with all the other members of the Troupe following the assassination attempt at Seirin Valley. They were imprisoned at Idoro and there were rumors that they were going to be put to death to raise solider moral. Kain was even working on an escape plan when "Gil" surprisingly saved them by appointing them his Imperial Guards.

Because Kain possess a similar build and height to Prince "Gil" he was ordered to wear armor and encourage the troops as the Prince during the battle at Zaim Fortress.
