Shinki was originally very nervous and easily-tempered. He's sometimes cold and rude towards anyone. He was shocked at Gaara showing him such compassion. Since being raised by the Kazekage, Shinki is described as the calm and collected leader-like figure of his team. Shinki is shown to be a respectful person when interacting with others, most notably referring to Shukaku with an honourific, something the Tailed Beasts do not hear very often.
