Ithnan

Ithnan (イスナーン, Isunān) was a member of the Al-Thamen. He also had some ties with Solomon.

Appearance
Ithnan is a tall man with a muscular build. He has long light-colored hair which extends past his shoulders. He covers his head with a turban, and wears a black and white checker mask, and a cloth that covers the lower half of his face. Under the mask, he has three vertical dots on his forehead, and sports a goatee. He wears a black jacket with a high collar over his robe. He also wields a mask with a handle as a Wand.

Personality
Ithnan is a serious person. He has a tendency to get to the point. He is also partial to Dunya. According to Gyokuen, he betrayed Solomon even if he deeply respected and loved him.

History
Back when Alma Torran still existed, Ithnan was already a member of Al-Thamen, and was fighting against fate and King Solomon. He also seemed to have a connection with King Solomon.

Zagan Arc
Ithnan is first seen coming onto the Torran Nation island posing as merchants, following Dunya Musta'sim and Isaac. They entered the Dungeon after Aladdin and the rest enter. Once inside, Dunya and Isaac attack Aladdin and his friends, however Aladdin is able to create a mirage of him and Alibaba and fools Dunya into aiming her attack into an empty field. Alibaba strikes at Ithnan and cuts his head off. Ithnan's decapitated head produces a snake, which bites Hakuryuu's hand prior to their departure of the Dungeon.

Second Sindria Arc
At the banquet, the night Hakuryuu, Morgiana, and Alibaba returned from the Dungeon, Hakuryuu's hand fell off his arm. Out of his hand, Ithnan emerged, with a lot of Black Rukh.

Sharrkan immediately attacks Ithnan, however his attack only enhances the problem as clones appear from the amputated parts. The clones aim their attacks at Sinbad and Alibaba, but are quickly defeated, however, the blood from the clones splatters on both Sinbad and Alibaba. It gives them the "Curse of Death". The blood will possess their blood vessels and dye their Rukh black, eventually transforming the victim himself into a completely different person ("Falling into Depravity"), as Ithnan explains. Opposing the transformation will cause the black and white rukh to destroy each other and rot the flesh. That being said, he "invites" Sinbad and Alibaba to become Black Kings and surrender to Al-Thamen's "Father". He says because of all the White Rukh in Sindria, he has trouble breathing, but he felt comfortable living inside Hakuryuu.

Ithnan leaves Sindria, but he is unexpectedly confronted by Sinbad, who appears out of a Transfer Magic Circle. Ithnan immediately amps up the curse he put on Sinbad. Ithnan tells Sinbad that the moment he gave Sinbad the curse, he became a doll Ithnan could manipulate at will. Just at Ithnan is about to amp up the curse even more, Sinbad starts to use his Magoi Manipulation to equalize the White and Black Rukh in his body.

He then brings out his own Black Rukh, revealing that his body has already been cursed, and that Ithnan's curse wasn't strong enough to take over. Sinbad then proceeds to gather in wind, while Ithnan is trying to realize what is happening.

Just as Ithnan realizes that Sinbad has already half-way "Fallen into Depravity", Sinbad uses his Extreme Magic, Foraz Zora, to defeat him. Foraz Zora blasts him and takes a big chunk out of a mountain. Sinbad finds Ithnan in the form of a doll (like the shape of a matryoshka doll). Sinbad crushes it.

Curse Magic
It is a magic that will possess a person's blood vessels and turn their Rukh black if it is white. They will then be reborn as a new person because there exist no one without darkness. Ithnan stated that if you try to oppose the change Solomon's rukh and the Black Rukh will destroy each other in the person's body and their flesh will rot.

Dunya Musta'sim

King Solomon
