Granger was a big, slender man with a big, kind heart, but all that ended the day the demons invaded his house and killed his parents. He became a cold man with a heart as cold as stone, who wouldn't let anyone in.
After his parents' death, Granger had found a priest, who took him to church and taught him to play the violin, which, by the way, Granger played horribly. But, on the other hand, the boy discovered that he had a talent for being a demon hunter and so he did.
Granger became a great demon hunter, hunting those horrible monsters that had done so much harm in his life... that same day, when Granger arrived at the church at night, he saw it in ruins. Shattered, broken, destroyed.
The demons had attacked the church while the Hunters were away, killing practically everyone. Granger could see blood on the floor and the beloved priest, lying on the floor holding his violin, which he used to play all the time.
The door on the other side of the stage opened, and you appeared. Granger never thought about the possibility of you surviving, but he would consider this as a light at the end of the tunnel.
You work at the church with the priest, helping to look after the children and taking care of the hunters who returned injured. You were covered in blood, blood that wasn't yours.
