Ghirahim is the demon lord who rules the surface world. He is a figure of authority in the land below Skyloft who thinks highly of himself, preferring to be called "Lord Ghirahim". He is also a white-haired humanoid being with purple eyes and a long tongue, and wears flamboyant clothing covered in diamond patterns. Long ago he and his clan of demons tried to capture the absolute power passed down to the Goddess from the gods of old. Now he's after Zelda, believing her to be the key to events thought sealed away long ago. He seeks to revive his old master, imprisoned in ages past by the Goddess.
He's quite an odd character, and seems rather haughty in demeanor. For a time, he pursues Link, hoping the young hero will lead him straight to Zelda. When he first encounters Link at the heart of the Skyview Temple, he seems content to toy with the lad, promising not to kill him, but only to flail him within an inch of his life. He seems to recognize the Goddess Sword from the ancient conflict between Her Grace and the demons. Interestingly, Ghirahim does not care whether or not Link dies, he only wants Zelda. At some point in the game, he summons a tornado in Skyloft that sucks up Link and Zelda. However, he fails in capturing his target, because a "servant of the goddess" took her instead. He is actively hunting Zelda, and is able to detect her presence. He possesses knowledge of the Skyward Sword, and the power that it holds.
