After becoming an S-ranker, Rio has become even more emotionless than before, but that's not the only change that happened to him.
His 'Sword Intent' also evolved to a higher form and became able to express itself in many types of forms and approaches.
A legendary skill is, simply speaking, a manifestation of a 'law' of the 'world,' and every 'law' of the 'world' is a semi-conscious existence.
It also has preferences for things it likes and dislikes.
The 'Law' of 'Sword,' which powers Rio's 'Sword Intent,' hates and loathes people who are cowardly and use their strength to bully the weak.
Now that Rio has become able to use his 'sword intent' to manifest the 'law' of 'sword' to such a high extent, he can even manifest it with such power that even the emotions of the 'law' itself can also manifest in his sword intent.
Rio has given this ability the name 'Approach.'
