Fiamma of the Right

Fiamma of the Right (右方のフィアンマ) is the leader of God's Right Seat and the main antagonist of the magic side in the Toaru Majutsu no Index Light Novels. His name is derived from the Italian name for flame, "Fiamma."

Appearance
He is a tall, skinny man with red hair wearing a red suit. He is always seen with a calm expression and a slight smile.

Personality
Among the members of God's Right Seat, he is seen as the highest position, and the other members are shown to be more loyal to him than they are to the Pope. Behind his calm personality hides a manipulative and ambitious person who doesn't hesitate to overstep his bounds past the authority of the Roman Catholic Church, use the entirety of Russian Orthodox Church, and even declare war against Academy City.

Toaru Majutsu no Index
The leader and center of God's Right Seat, with him stating as long as he's alive, the positions of Acqua, Terra and Vento can be replaced, but if he's gone God's Right Seat as an organization would also be gone beyond salvaging.

Acqua of the Back and the Amakusa Catholic Church
He seeks Touma and Index, the former for his power, which Fiamma considers the Holy Right, and the latter for her knowledge in inaccessible forms of magic. Fiamma also uses his status as the current Pope's mentor to classify Touma as a heretic, thus enabling him to fulfill his purpose to capture Touma. He holds enough power to blow away all of Rome in one blast, but 2/3 of the damage is avoided by the Pope absorbing it to protect the city, resulting in the Pope being hospitalized; however, part of the Vatican was still damaged by the attack.

Carrisa and Curtana Original
He made his way to England, activated the external control of Index's spiritual artifact control, Johann's Pen, during the Magic Civil War and also meets Touma, which leads to the both of them fighting. Using his Holy Right to attack Touma, it is destroyed but suddenly regenerates. According to Touma, Fiamma's Holy Right is very similar to his Imagine Breaker, except the arm is manifested outward.

Fiamma of the Right and the World War III
In Volume 20, he suddenly appears during a meeting between Touma, Lessar, Vento of the Front, and the leader of Elizarina, a country recently separated from Russia, and manages to seize Sasha while fending off the others. During the fight, Vento notices the flaw of Fiamma's power, that it has a limit and reached it while fighting Touma and corners him, but he then uses Index's remote control once more to keep his 3rd arm—even though it disintegrated physically— and leaves with Sasha captured after defeating all of them.

During the fight it turns out that he knew about Touma's memory loss and told Index through a telepathic link while she was forcibly still in her Johann's Pen Mode. He then tells Touma to stay alive because he needs his Imagine Breaker for his powers be to complete.

After he summons Archangel Gabriel and the Star of Bethlehem to fix the elemental balance that affects the creation, he gains full control of the Holy Right. While Touma is aboard the Star of Bethlehem, Fiamma severs Touma's right arm and then absorbs the Imagine Breaker into his Holy Right. Soon after, Fiamma notices that a massive and overwhelming power, which his own pales in comparison to, is forming from Touma's wound. Swallowed in fear, Fiamma is unable to move; he can only listen as Touma seems to converse with the incredible power that is welling up from his wound. Touma then crushes that power with an even greater power, which causes his right arm to regenerate, along with the Imagine Breaker. Touma then confronts Fiamma about his objectives and points out that, if Fiamma were really the strongest existence, and if his Holy Right adjusted its strength according to the difficulty of the enemy, then there wouldn't be a reason to go around and gather up parts from churches and cathedrals around the world. This revealed that it was all insurance to mask Fiamma's fear, as he was unsure if he really had 'power enough to save the world,' on his own. Touma explained that there was no way that someone who hadn't already saved the world could know if the power to save it really existed. In differnece to him, Touma had seen with his own eyes the instant that someone's 'world was saved.' With the conviction lost and defeated, Fiamma is told by Touma that he still has a future despite all of this. Later on after the battle on the Star of Bethlehem, Fiamma tries to change everything that he's done and is attacked by Aleister Crowley in an ambush. Aleister destroys Fiamma's right arm because he had seen the true power that was residing within Kamijou Touma, so Aleister had no choice but to come and kill Fiamma with his own hands. Fiamma unleashes his Holy Right, as he can't let Aleister stomp on the world that Touma had protected, but is defeated and nearly killed.

Before leaving, Aleister said that Fianma had the right goals, reaching "La persona superiore a Dio," (神上) but tried to comprehend the 'right hand,' the Imagine Breaker, and the "One that cleanses God and exorcises the Devil" (神浄討魔) within the level of Christianity instead the Age of Horus and that his format was his mistake.

Afterwards Fiamma is found barely clinging to his life by Silvia and Ollerus, who picks him up and asks him to tell what he knows about the Aeon of Osiris of his, and what he saw of the Aeon of Horus Aleister has.

Abilities
According to him, he holds the symbol of miracles, the Holy Right (聖なる右), which has the power of the archangel Michael, but he cannot use its full potential as of yet. When his power is used, a mirage- and a bird's talon appears from behind him, which is his main form of attack. However, he has revealed he can now use any symbolism magic that has anything to do with the Right Hand, such as how archangel Michael slayed Lucifer with his right hand, the Son of God heals with his right hand, and one needs to record bibles with their right hand, plus many others. Touma likened Fiamma’s power to having "One-hit KO" in an RPG alongside the other options like "Fight," "Items" and "Magic," thinking that it’s really unfair.

With his Holy Right, he has shown he can do the following:
 * The strike that ends everything it touches: this attack destroys everything it touches without any destructive force.
 * The strike that reaches everything when swung: this attack delivers itself right next to its target without any speed, thus allowing him to move anywhere at will.
 * He can produce a 30–40 km-sized sword made of flame.

Quotes

 * (Vol.16) "The Holy Right that symbolises all powers of miracles, no matter it be magic or demonic arts, it will destroy all without differentiating between them. Even in the past it has sealed the demon lord Lucifer into Hell for a thousand years, the power of the Right that let the human realm have a thousand year of peace."
 * (Vol.16)"The 'Son of God' could use His Right hand to cure the illnesses of the sick and revive the fallen. It was the Right hand that was used to draw the Cross and scatter the Holy water used for the Baptism. Furthermore, the Right hand of 'The One Alike to God' is said to be the greatest weapon in history, having cast down an uncountable number of Fallen Angels; even 'The One Who Challenged the Light' was defeated when opposed by the Right hand of 'The One Alike to God'. It is such an overwhelming power.”
 * (Vol.16) "To handle an overwheling power, an overwhelming knowledge is needed."
 * (Vol.20) "Seriously, still having a strategy meeting at this stage, you people are beyond late."
 * (Vol.20) "Today's my lucky day. I thought I'd need to put in more hard work, but obtaining my goal was surprisingly easy."
 * (Vol.22) "I'm about to save this world. Therefore, I have no more use for you. Feel the glory, meatbag. Your value as a human being, obediently let me have it."
 * (Vol.22) "I did not succeed. I had the power same as that of the Son of God, power that can save the world. But I could not save the world."
