There are no difficult bosses if you prepare properly. However, I will say that Dark Anima in NSG is the hardest boss I know of. She remains unbeaten without the use of Zanmato.
I was actually talking about Shinryu in FFV, who is a pain in the arse if you don't have Dragon Lances.

Dark Anime really isn't that hard, her low luck is her downfall.
