Uragirimono -- Sephiroth. On account of how that's the word he used for Zack at Nibelheim, the one that's always translated as 'traitor,' but the kanji show a blade cutting through the back, a literal backstabbing. And the one thing Sephiroth never did was to stab from behind, after all... that got left to the hero of the story... XD

must go and see if the first batch are baked and done yet!
