This time, Oliver got a great problem. His father got a new job! Isn't it a good news? No, he had a job at Oliver's school. It means that if his father makes some problem, he will also have some problem.
Unfortunately, Oliver's father was not so good at making potion. He was a helper to make potion, but he couldn't do well on it. And also, there was big wall to climb over. Casper, the genius young wizard.
Casper disgraced Mr.Moon, so Oliver was really angry. Then, he decided to have a magic confrontation with Casper. They were both good at magic, so they got the same score when they realized they didn't disgraced each other. Casper also thought Oliver disgraced him, and they were just tricked by the bad guy, Bully Bogeywort. Maybe they became good friends, don't they?
