Actual Translation!

Duran DID wield the Sacred Sword, and the Demon he fought in his 7* lore wielded the Sacred Gem! That is what Gumi got mixed up, likely. Also, for the Sacred Blade, it is a BB gauge adding item, and Duran has a 10 BC fill on his BB and SBB, so it fits. It is very possible however, that he was based on both.
