Chishiya is mostly seen sneering even when he is angry unless he becomes emotional or regretful, which occurs only a few times. Heavily intense or horrific events don’t ever have him falter. The only times in the series he’s ever seen truly disturbed is the aftermath of the Witch Hunt and at the death of Keiichi Kuzuryu. He is calm, highly intelligent and manipulative, and analytical at all times, making him a potentially strong Hearts and Diamonds player, even though he claimed to not be suited for Hearts. This allows him to triumph in games that require defeating other players, yet because he declares to be uninterested in understanding the human heart, Diamond games remain his strong suit. His capabilities to remain so calm in dangerous situations stems from the fact that he has no interest in the concept of life, both his own and others. To others, the Borderlands are a situation of life or death, but to him the games are just simple games. The truth is, he lacks a will to live. He doesn’t know what he’s living for, and was just interested in finally finding someone that was “interesting” in the Borderlands. Although he acts c*cky, it’s clear he doesn’t like himself for who he is. He couldn’t help shunning people’s good will and intentions, he couldn’t get by without hurting and manipulating someone. For what purpose does he live? He says that in the end, he feels like the only he existed was to display “just how empty a human can be”
