As the king of Hoshido, Sumeragi was benevolent to his people and treated them fairly. When he was not busy with policies, however, Sumeragi cared deeply for his family, having fun with them as he wanted to be the best father he could. He cared very little of being the Hoshidan King and took little enjoyment out of it. However, in the Female Avatar and Yukimura support conversations, it is revealed that he would always be happy to see his children after a long day. Sumeragi also has a different view in warfare; in a support conversation between Yukimura and the male Avatar, Sumeragi told him that there is no point in killing soldiers who have surrendered and disliked killing the enemy without letting them have a chance to surrender.
