Yukiyoshi's personality was stated as "terrible" and said to be the complete opposite of Yukisada's. He is very grumpy most of the time and could be very straight forward too when expressing his disdain to something. He also has a bad mouth, often swearing, however he tries not to swear too much around his brother. To the people he do however tolerates or likes he can be rather respectful towards them and addressing them in a respectful manner. He generally has a pretty disagreeable personality.
