Key Dorrikey (キー・ドリッキー Kī Dorikkī) the "Inviter of Fresh Corpses" (死斑誘致者 Shihan yūchi sha) is a self-proclaimed "Great Detective" and a clear admirer of the Sherlock Holmes stories by Arthur Conan Doyle.
His modus operandi when conducting an investigation is to bite and subjugate everyone connected to a crime to force out a confession. While this method has produced many a success, the police are growing ever more wary of how Dorrikey manages to catch criminals without doing any actual detective work. Some even suspect that he is the mastermind behind the crimes he is solving.
Dorrikey wears a monocle, and constantly smokes out of a Holmes-inspired pipe. His clothing is weighty and 'fit for a nobleman,' though it contrasts with his youthful features and 'somewhat unbalanced mien.'
