Michael

Michael carries souls from Judgement (after the In-Between) to Paradise if they are found righteous. Or if a soul is already righteous when it arrives to Heaven, he carries them to Paradise. (His role is not to be confused with that of Samael who transports souls to Sheol; or Ramiel who transports souls to the in-between; or Azrael who separates soul from body)

Part of the Archangel Conspiracy, Michael serves as the strict mastermind.

Primary role in plot: smuggle good souls into the in-between which is easy because taking souls to paradise his role. [1] The second and third roles of Michael in Catholic teachings deal with death. In his second role, Michael is the angel of death, carrying the souls of all the deceased to heaven. [ref]
