- "A Heartbeat that lasts for eternity. Lives consumed in soundless balls of fire. No one can tell when the world is displaced and the Flames of the Crimson World sweep over all."
- — Alastor's opening narration of the first season.
Alastor (アラストール Arasutōru ) is the God of the Crimson Realm to whom Shana is bound. His true name is "Flame of Heaven" (天壌の劫火 Tenjō no Gōka ), but he is also referred to as the God of Retribution (天罰神 Tenbatsushin ) and is greatly feared by Denizens. Alastor is the strongest of all Lords and Denizens, a "God that can kill Gods (神をも殺す神 Kami wo mo Korosu Kami ) who is considered the only being capable of destroying the "God of Creation", Snake of the Festival. Even so, he tries to keep the Denizens from consuming Power of Existence.
In his sealed form, he expresses his will through a divine vessel called Cocytus, which takes the form of a pendant when he is under Shana's contract and a hand accessory in Mathilde's case, both forms sharing a pitch-black gem.
Alastor's true form is a massive creature with powerful limbs and horns that resembles a Minotaur. He has large wings with membranes the color of the night sky and burning eyes. He is completely covered in flames which are powerful enough to incinerate everything in his path. A black mass is hidden inside those flames.
In the novel, he is described as having a voice resembling the roar of distant thunder.
Alastor is like a father-figure to Shana and cares for her, as he had watched over the future "Flame-Haired Burning-Eyed Hunter" as she grew up and usually tells her stories (particularly about his former Flame Haze, Mathilde Saint-Omer). He seems to have the personality of a typical king (in his case, of another world), as he speaks in a regal tone and is ever mindful of disciplining Shana. He and Shana seem to have a parent-child dynamic at first, but Alastor is aware that Shana must grow up and maybe trying to adapt. Despite his serious nature and regal mannerisms, like a hapless father struggling to deal with his child, he tends to neglect what some would consider to be common sense and stumbles when it comes to matters he is unfamiliar with, like human relationships. As a result it is not uncommon for him to be reprimanded by his closer associates, in particular Wilhelmina Carmel and Tiamat, a treatment he would sheepishly endure. He is commented by the Snake of the Festival as the "one who wishes for judgement" (裁きたがり Sabakitagari ) and the "retribution-crazy God" (天罰狂いの神 Tenbatsu Gurui no Kami ) or simply "retribution-crazy one" by Denizens.
The Great WarEdit
Before the Great War, Alastor chooses to not participate in the sealing ceremony of the Snake of the Festival. However, he actively participates in the conflict following the Snake's sealing, where he, under a contract with Mathilde Saint-Omer, defeats the forces of the Crimson Realm, and ultimately, the leader of the Crimson Realm organization Töten Glocke, Asiz. Unfortunately, the victory is due to a sacrifice in his contractor's part, as his beloved Mathilde perishes the moment she summons Alastor through the ceremony called Tenpa Jōsai (Heaven-breaking, Earth-sundering).
After the end of the Great War, with Wilhelmina Carmel and Merihim, they head off to the Tendōkyū, where he stays inside a Treasure Tool called Caina as the Flame Haze searches for the candidates for the next "Flame-Haired Burning-Eyed Hunter". Hundreds of years later, they finally found a child perfectly fit to be the vessel of the true Crimson God.
Second Great WarEdit
After Shana's defeat, he follows Yūji and a few member of Bal Masqué then travel to the rift between the human world and the Crimson Realm, the place where the body of the Snake of the Festival is sealed to know his intentions.
Through various battle and tactical planning, Shana reunites with him and her team returns to fight Yūji Sakai as they realize the new world would cause an imbalance of Power of Existence in the far distant future if Denizens consumes Power of Existence recklessly. Through ensuing battles, Shana and Margery Daw successfully re constructed the Unrestricted Spell to include a Law that humans can never be consumed in Xanadu. This is a last ditch effort as Shana's team is too small to prevent the creation of Xanadu, so they merely wanted to protect the Xanadu humans instead. As they feel relieved that their plan worked, Shana is agitated to see Yūji Sakai smiling.
Yūji Sakai, having foreseen such a plan, revealed that the Unrestricted Spell is a secondary effect. In reality, the only requirement is to wait till midnight so that the Reiji Maigo would refill, during that time he ask the Professor to place a special Unrestricted Spell to obtain an extremely vast amount of Power of Existence under his control, where he can direct it to the creation of Xanadu and nullify the Law placed by Shana. Shana and her team has not won, but clearly lost, and can only watch helplessly on the creation of Xanadu. However, Yūji Sakai, as the God of the Festival hears the Denizen's wish as well as the Flame Haze's wish, and did not undo the Law placed by Shana.
Post-Second Great WarEdit
He, together with Shana and Margery Daw, in the aftermath, faces Yūji. During the battle Yūji activates Lamie's Unrestricted Spell and cast it on Kazumi Yoshida, with the last plea for her to agree. The spell activates and it repairs the distortions caused in Misaki City and restored the existence of those eaten by Crimson Denizens.
Shana asked Sakai Yūji what his intention is, and he replied that in order to atone forthe killing of many Flame Haze and, indirectly, Humans on his quest, he will travel to Xanadu alone to teach Denizens and humans to coexist peacefully, even if it takes thousands of years so that he can finally be together with Shana without guilt. Shana and Alastor, however were furious with his philosophy of severe self punishment, They used their tremendous strength to overpower and defeat Yūji. Later, after Shana and Yūji embraced and kissed, the Spiral Organ's Unrestricted Spell activated and Sakai Yūji becomes a "solid existence", as prophesied by himself - something more then a normal Torch or a Mystes. As Yūji Sakai and Shana delights at this revelation, he, Yūji and Shana departed to Xanadu.
Shakugan no Shana-tanEdit
Dengeki Bunko 2007 Movie Festival SpecialEdit
When Yūji and Kazumi were going to the movies together, Alastor misinformed Shana that the movies are a place where couples fall in love. Later, in the theater, he is appalled to see Yūji with his head against Kazumi's breasts, even though Yūji was unconscious at the time.
Alastor loves Shana like a father does his daughter.
As Shana's guardian, Alastor's surface and primary disposition is to act unpleasantly harsh and severely towards him. However in truth, after overcoming many battles with him, he grows to have the same amount of trust in him as Shana does, though he would never tell this to Yūji and would still act severely towards him.
Alastor uses the rude pronoun "kisama" (貴様) when talking to him and often calls him a fool. The severity of his language towards Yūji is toned down in the anime series.
He loved Mathilde with all his heart. Even then, he would not set his responsibilities aside just for love.
Powers and AbilitiesEdit
Tenpa Jōsai (天破壌砕, Heaven-and-Earth Sundering): Tenpa Jōsai is the summoning of Alastor himself, capable of burning everything to ashes. Unlike other lords that requires a lot of Power of Existence from human to manifest their forms, Alastor's contractor can perform a summoning ceremony of the God of Retribution that, instead uses Denizens around him as the source of the Power of Existence. This method is his Flame Haze's last resort; as no Flame Haze had survived after using it before. But Shana can endure it due to her power. In the novel, the only time Tenpa Jōsai is performed is in the final battle of the Great War. Mathilde summoned Alastor as the last resort the stop Asiz from succeeding his plan to create the entity from Tis (his beloved contractor) and his own existence aka the "Heir to Both Worlds".
