Hearing that Brian possessed a Hereditary ability left everyone confused. Any person with a hereditary special ability is always able to challenge foes at least a level ahead of them. In the past, a C rated guardian with a hereditary ability once fought an A rated guardian to a tie, shocking the world! Only then did the world look into the difference between hereditary abilities and normal abilities.
What they couldn't understand was why someone like Brian who had a strong background and was already guaranteed to reach the A ratings coupled with his hereditary ability would be an introvert. Even as an A rated guardian this youth will still be able to battle 'S' rated guardians and still win! The only time when someone like him should be scared is fit faced with a disaster realm opponent with a hereditary ability! And this is very unlikely to occur, so they couldn't explain his behavior since those with this sort of opportunity are mostly tyrants, just like Zero and his group.
