Hero Syndrome

Hero Syndrome(英雄症候群, Eiyū shōkōgun) is a magical disease.

History
Hero syndrome is a magical disease that has a possibility to appear in one person out of 10 million. They are far more rare than magicians. The persons body is constantly using mana at all times. This causes the person to be far stronger than a normal person. Excluding a magician opponent, they are almost the strongest in inter-personal combat, however as compensation, they will immediately end up dying due to starvation if they don’t take in excessive amounts of calories. If they are born to a commoner or lower class noble family they usually end up starving to death before they can make use of their talent because of their birthplace
