Several years after his father went missing, Leah, a rural teacher, went to the imperial capital to locate him. In response to the headmaster's introduction, he applied for the position of Royal teacher and passed the examination to become Prince Porter's tutor. Upon finding Prince Porter trapped in the tower, he was astonished to discover that he was a savage Orc who did not speak human language. When Leah realized that he couldn't escape, someone locked him in the tower and taught the prince the lessons written on the articles and instructions that were sent into the tower through the door.
