Legend of Zelda: Skyward Sword - Demise Reborn [HD]

While Link was fighting Ghirahim, the ritual to revive Demise continued working and was completed. Ghirahim offers Zelda's soul to transform The Imprisoned (Demise's abomination form) into the true, menacing demon king. Apparently, Ghirahim was nothing more than Demise's sword. The king offers to battle Link in a place where they won't be bothered by distractions.
