Yes there are no magic usable by players, but there are magic/magical attacks used by NPCs and monsters. Second Floor Boss, Asterius the Tarius King, used lightning-type breath attack that Kirito described as magic. The fifth floor boss, Fuscus the Vacant Colossus, could appear anywhere in its room due to the WHOLE ROOM being part of its body.
