Before you give set your undying hatred for his parents for "abandoning" him, don't. There is a reason for everything. Look at the bubble that he was in. If they were going to just abandon him, they wouldn't put him in that. It must be a Superman situation where the parents were about to be killed and they sent their son away from danger. I am sure of it. They clearly knew about his mana-less condition when he was born. If they didn't love him, why would they raise him for all that time with such love.
