^^ Yeah, he does. And all of their memories and magical skills as well, in accordance with the well-known "Archer's Left Arm" principle. Fortunately, Lio won't have to deal with his body turning into swords or something annoying like that because (a) none of the KnK Magi use a type of magecraft wholly derived from their own Reality Marble, or indeed have Reality Marbles at all (unless you could count Hounouden Rokujyuyonshou as a partial example) and (b) because his body is already made of BLACKLIGHT/lions, so anything else can just bugger off.
^ Have no fear. Ryougi's too awesome to get consumed.
