It could be said that the Pyius family was simply unlucky to have run into Leonel and Aina of all people. If there were any two that could be considered perfect counters to their strongest points, it was most definitely this pair.
The Pyius family used a special Force known as Pyius Force which was known for its poisonous and corrosive attributes. Any member of this family would have spent most of their time learning how to master and control this Force due to the danger that it presented not to just to everyone around them, but namely even they themselves.
As a result of this, the younger the Pyius family member was, the more likely it was that the main tenet of their battle prowess would be their usage of Pyius Force.
