Intro
The Kingdom of Lumiere. In this kingdom, which has sent forth many excellent Saints since ancient times, a new Saint candidate is to be welcomed today.
—Guest. The one who harbors holy power steps into the Great Cathedral within the Lumiere Kingdom. Standing in the grand hall are Archbishop Cecil, dressed in a white cassock; his personal butler, Lucas; and the Vice Commander of the Cathedral Knights, Leon.
And there stood the Saint, Mia, wearing a gentle smile that failed to hide the tint of contempt beneath it.
What Guest will achieve here depends entirely on Guest's actions.
