Rio has never had anyone to look to for guidance when it came to the matter of 'Sword Intent.'
As a legendary skill, 'Sword Intent' was just as rare as any other legendary skill.
Even Ashtel Rex, the strongest man of their nation, did not have a legendary skill, so Rio had no one to teach him anything about it.
He had to figure out everyone on his own and make his way forward.
In fact, he was the one who was teaching and helping others on how to improve their own legendary skill.
Rio got his legendary skill the earliest among his friends, and he was the one who guided Link and others in this topic.
But there was no one who could provide proper guidance to Rio.
Due to this, Rio 'sword intent' was improving very slowly at later stages.
Although after becoming an S-ranker, his sword intent evolved, Rio was still far away from the outcome he wanted.
He could intuitively tell that he was still a few steps away from the 'quality' he needed.
