While still reeling from this shocking epiphany, Rio also comes to learn that he possesses extremely potent magical abilities and uses his new powers to solve the kidnapping case of a little girl. His good deed is acknowledged, and he's rewarded by being enrolled into… a prestigious academy for noble children...?
