Fan Casting Magical Minority in Sort by Tropes

In order to show the world that minority characters are not bad people, one will step forward to help a "normal" person, with their pure heart and folksy wisdom. They are usually black and/or poor, but may come from another oppressed minority. They step (often clad in a clean, white suit) into the life of the much more privileged (and, in particular, almost always white) central character and, in some way, enrich that central character's life. If the Magical N***o (also known as Magic N***o or Mystical N***o) is from a society of Noble Savages, expect an Anvilicious Aesop about the failings of the protagonist's society — which usually leads to the protagonist "Going Native".
