Mario was once a simple student who realized his school, Heights of Labranza, was in decay due to its poor policy, incompetent handling of conflicts and rules that made no sense, so he made a contract which he gave to the principal, and after she signed it, the principal had to leave her position, leaving Mario in absolute power as a result. Several changes were made to the school, and even though its beginnings were controversial, it's widely accepted that his period is the best one.
