These are all of the characters you get to use in game play.
Each character's category is reserved for things that are unique to them. Their Initial Equipment, or things no one else can equip. Even the DG armor is pushing it a bit, since it is so obvious.
That means Albert doesn't have any armor in his category; Miranda has none in hers.
Albert has weapons in his category available once he joins. Same with Miranda. The early characters stick to what is obtained when they are there. There is no overlap.
