He was formerly a middle-eastern prince who had dreamed of becoming a great warrior and great king after his father. The prince slowly started to sense the Power of Existence. One day, he followed his father into a battle with other countries and discovered a certain Crimson Denizen who was fond of eating talented and courageous humans. Realized that the creature was aiming for his father, the prince engaged that Denizen. The prince fought the Denizen but was defeated. Then, Behemoth appeared and he made the contract with the prince and defeated the Denizen, but he didn't kill the Denizen.
He then came back to his country, but no one recognized him, because he gave up his existence as the price of the contract. He then traveled around the world to find the Denizen. Hundred of years passed, his country was destroyed. At the end, he found the Denizen and ended his revenge.
In present time, Khamsin is one of the few Flame Haze who went through the ancient war against the God of Creation, "Snake of Festival". At that time, he didn't work as the tuner, but as the warrior to protect the balance of two worlds along with his comrades; as many of them sacrificed their lives to seal away the God of Creation.
He came to Misaki City and make Yoshida Kazumi as his guidance. He then helped Shana and the others to fight against Dantalion. He didn't join the fight at first, but at the end he joined it. He made a monster from rocks, and throw rocks with it. Dantalion then escaped, and he tuned the city with Yoshida's help.
