Himuro is soft-spoken but has confidence in himself. Unlike the other Senior Managment at Carrier Man Trading Co., Ltd., he speaks his mind and is not a "yes-man." He is very fastidious, keeping his three desk pens arranged in perfect order. Overall, Himuro is self-assured, but his biggest hubris is his stealthy manipulativeness and ruthlessness in his nature. However, he does have close relationships to some people he shares common ground with, such as Washimi.
