Poe is 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 and cockiness when he isn't comparing himself to Ranpo. He isn't known to have many friends. With the exception of his raccoon, Karl, who he considers his greatest friend.
