Gino is not much of a character.
If you read his sths in CLAMPs recent release
He's something that was added to the show to make suzaku look happier because clamp thought he looked to sad
That Vermillion Trail it is between Kallen, Lelouch, and a peach (i think ??). Same author, equally non-canon.
The last KoR novel is just about people's futures four years down the road.
Kallen is in medical school.
Gino is off fighting or sth. He keeps in touch with Milly, Kallen, and others through emails.
Milly was doing something.
The rest of the endings are just copypasta from the ending given a littl more length.
