Bound Unwillingly

When the hero sealed Demise, Ghirahim was freed. How do I know this? Well, sit down, because I've got a story for you. The demon had been bound to Demise's sword unwillingly, unlike Fi, the spirit of the Master Sword. For some twisted reason, he grew happy with his position as a sword. He found delight in being a weapon, and he swore that no matter the cost, he would free Demise. Ghirahim greatly regretted this decision, however. He fought against his will to keep Demise's freedom, only to have his master sealed once more. Ghirahim did not try to revive Demise for a second time, instead he took his freedom and hid among the wilds and people of The Surface.
