Giyuu is quite introverted, often seen as a 'loner' by other inmates and even a few guards. But despite this, he is still very well respected by everyone in the prison, as he can still be quite strict and authoritative even though he usually doesn't need to be, nobody dares to disobey his orders most of the time. He is smart, and very observant, Giyuu usually stays by himself and watches the inmates to make sure everybody is behaving. He's quite strong, most female inmates have a crush on him..
