Together they form Makenshi, meaning evil/cursed/dark/devilish swordsman and most definitely not Mystic Knight. The Japanese name used for Mystic Knight in Final Fantasy is Mahoukenshi which translates to magic swordsman.
I don't think I conveyed my point well enough. Cecil uses Dark Swords. What is a dark sword? Is it a katana? Is it a broadsword? Is it a sabre? Yes and no. It could be anything, just as long as it's imbued with darkness.

Other than using swords... what carries over to Dark Knight?

I understand the translation, I was saying Mystic Knight to make it easier to discuss.
You ever watch Final Fantasy Unlimited? In it, the main character uses something called the Magun. The Demon Gun. Does it wield the power of darkness? No. It's used as a tool for summoning the various espers/eidolons that we know from the series. The conclusion here is that "demon", when used in Japanese as a descriptor, does not necessarily equate to darkness. It's mostly synonymous with "magic". "Mahou" can easily be taken as an evil force or demon magic, depending on what the author of a story wants to do with it.
