Dandy

A man wearing a brown trench coat and hat that is seen running from the same police officer in almost every episode (almost like a Zenegata/Lupin relationship). It is never explained why the cop chases Dandy as he is never seen doing anything wrong and even helps out Ink every now and again. It is later revealed that he is the King of the Magical Kingdom and Mio's partner. He turns into the form of a small dog while still wearing his hat and has a lolicon fetish as well (drooling and having a nose bleed when Mio changes, a combination of Arc and Kaksu's reaction).
