Exterminating Cecilia is no harder than deviating from the Score for General Van Grants. Even under the most extreme pressures, Van is cool under fire, unwilling to bend his will to the demands of fate. He's a man of many masks and layers, he's come into his own during his second appearance, crushing Fujin like a bug. Cecilia's a little better than the wind aligned girl, but not much. Her noted fraility to physicals and reliance on magic absorbtion to win her fights does her no good against the power of VAn's deadly physical strikes. Buffing? Delaying tactics? Worthless, Van has the ability to smash past any such attempt. Imperial Slaughter, Ancient Requiem.. the pain goes on, and the Mystic Artes keep on smashing. Cecilia can throw up all the puny Shield spells in the world, it won't stop Van from ending the fight with a single action and sending him for a tremendous showdown with whatever Final Fantasy villain wins in the top part of the bracket.
