He was a failed child prodigy. After all, if he was a real prodigy, he would still be something in the business or have a business of his own. Instead he's an arrogant high school boy living with his big sister. But looking at it objectively, Sento only led the park to a disaster with her nonexistent (entertainment, management, and business) skills, so how on Earth could she have had the wits to choose and convince the right person to save the park? Instead she chose Kanie for whatever reason. Maybe due to some magical fairy guidance. Still, at least he's trying, trying really hard. Probably he's still far better than some random joe from the streets since he does have a distant background in the entertainment.
