Graham

Graham is the first "partner" whom Tiara summoned, who appears in episodes 5-6. He was, however, disfigured in the process. Tiara had to fight long in order to possess him, as well as fighting off a demon formed from her own shadow, which now is the demon-like creature she can become in battle. Because of this Graham initially feared Tiara, but his fear soon gives way to a fierce loyalty. Graham feels that Tiara's love for Kagetsu is unhealthy and sees Kagetsu as the source of her pain, though most of those thoughts came from his own affection for her. ~!Graham attacked Kagetsu in the final episode when Kagetsu steals The Throne of Yord (containing the soul of his sister Sara). Unable to match Graham's superior physical strength, or just unwilling to use force against Tiara's partner, Kagetsu "neutralizes" Graham in the struggle. As Graham's physical form was perpetuated as an extension of Tiara's magic, having Tiara's magics neutralized eradicates Graham's body.!~ (Source: Wikipedia)
