Poe spent six years trying to come up with a plot that could finally outwit and defeat Ranpo Edogawa, showing that he will work hard at something he cares about, he's determined, highly intelligent, competitive, passionate, a perfectionist, and introverted. He often talks too quietly for others to hear and he's very socially awkward and hates crowds and large social gatherings. He's rather wealthy and sometimes reckless with his money and tends to have random outbursts of confidence.
