Shibirin's facial expressions didn't resemble those of a happy person, nor did they show tha he was somehow depressed. No, they were neutral, nothing more than a blank line that stood in as his smile. He observed the two ninja, taking in a more interest towards the one who claimed to be a Hyuga clan memebr first, before focussing on the other. "Hmf, i am up for a fight, but saying in advance, don't bother telling me how strong you are or how you're going to take me down. Words, when it comes to fighting, are mere distractions and only a pittyful ninja would use them to back up his pathetic, 'so-called skills'", he said to them, not picking on anyone in particular.
Shibirin had fought and beat a ninja, back in suna, who approached himself as stronger than Shibirin. They both were swordsman and both used ninjutsu, but when it was time for them to test and see who really was the best, Shibirin came out on top. This just proved that one shouldn't praise their abilities so soon in life, for it will be those they mock that end up rising on top of them.
