Sakon was distinguished by a malicious, self-confident and mocking nature, constantly taunting his enemies and enjoying battle, deliberately dragging out the fight. He considered himself the strongest and fastest in the Four and never missed an opportunity to boast in front of others. Ukon, on the contrary, was more hot-tempered and impatient, often pulling his brother back when he got carried away playing with the opponent. Despite the difference in temperaments, the twins got along perfectly and acted as a single whole. Sakon acknowledged Ukon's seniority and obeyed his orders. Both brothers looked at their enemies with extreme contempt and called them "trash." Sakon had a habit of waiting and tormenting the target, while Ukon preferred quick and decisive actions. Their arrogance was backed by real strength, which made the duo extremely dangerous. They treated their allies with the same rudeness, but within the group they observed subordination. Any display of weakness only provoked their mockery. Both were extremely vindictive and never forgave offenses.
