hikari no 4 senshi is the title (sans subtitle, "Final Fantasy Gaiden"), with four warriors of light as a translation. Dunno about what I suppose are names, but I guess the site's been updatin'.
It's...the title. Even were it a character or something, it wouldn't need to be distinguished, like Gilgamesh. Or do you mean that the titling isn't apparent (which can be handled by a wiki), or that the qualifier would help in searches (the final_fantasy implication would cover that)?
