Technically, "Mage" is series title, not a name for protagonist Kevin Matchstick. The titular "Mage" probably refers to the wizard (Mirth, or Merlin in disguise) that he meets. This is a story of existentialist engagement and can be read as an allegory for Wagner finding his own voice as an artist.
