The Two Assassins are cold inside. They feel no remorse, pity or any other emotion for anyone. They have no mercy, and do whatever their master tells them to do.
The Two Assassins claim they were born into the service of their master. However, this is not true. They were born into a loving family. A few days after being born, they were taken from their home. They then endured a tough childhood of training. This hard childhood took all the emotion from them. They do not remember their family, and so believe they were born into their master's service.
