Aiwass

Aiwass (エイワス) is a higher dimensional super-being summoned by Aleister Crowley. An entity ranked above angels, Aiwass was Aleister Crowley's former mentor, and the true author of The Book of the Law. Aiwass also refers itself as "DRAGON," saying it's more accurate as being called an "extraterrestrial intelligent being," "holy guardian angel," or "the true master of the secrets that shaped modern western magicks."

Appearance
Aiwass' gender is unknown, though Aiwass has been described as having feminine slim body and long hair. Aiwass has been described “An Angel that cannot be explained by holy books or theology. And at the same time, in this world which God has made it symbolises material beyond God’s control; breaking through the points which God has decreed for fate…" by Fiamma of the Right

Personality
As opposed to Aleister Crowley, who judges things on their efficiency, Aiwass judges things on whether it has value or not. It seems disinterested in the affairs of the world, though showing interest in both Accelerator's and Kakine's abilities. It also knows of Crowley's true intentions, being his former mentor. It was also the one who prompted Hyouka to go to Russia to participate in the war; this decision may be against Crowley's best interests, if so it implies that Aiwass has plans of its own.

Due to its own disinterest in most things, Aiwass offered Accelerator to let him destroy its physical form, saying it'll buy him time to save Last Order, and that it doesn't matter if it vanishes, as it can always return in 10,000 or even 100,000 years later. In addition, it also doesn't care about Aleister's threats about losing its status as above mortals forever, saying that it never asked for its powers in the first place and it would not matter either way.

Battle Royale Arc
After the events of volume 15 the first clue about its existence was found when Tsuchimikado Motoharu checked the info found in the UNDER_LINE, that would mean that its secrecy level is higher than the other dark organizations within Academy City.

DRAGON(≠Angel) Arc
As Shiokishi said "DRAGON is everywhere. Look, right now it’s behind you," Tsuchimikado Motoharu, Musujime Awaki and Etzali and shortly after that, the member of the Board of Directors, got knocked out instantly. Aiwass appeared before Accelerator and presented "itself" as "the one who once taught the bare essentials of the necessary knowledge to the eccentric magician Aleister Crowley."

Aiwass’ form is still incomplete, as it lapses into 'Angelic gibberish' every now and then since human language can’t convey what it wants to say. Accelerator cannot comprehend Aiwass or what it’s suggesting at first, as to him, its actions of showing up in front of him are illogical, when Academy City tried so hard to hide DRAGON’s information. Aiwass explained how humans never change, and that history is always flowing on regardless of what humans do, so even if it were defeated, it could always come back in another 10,000 years, or even 100,000 years, as it's not really of this world. Aiwass also said though Aleister always improves his plans to make them better after unforeseen events, cracks are starting to appear. When Aiwass revealed Aleister's plans to replace Last Order, and that if it was defeated, Last Order might be saved, Accelerator decided to just kill Aiwass.

Accelerator charged at Aiwass, though his Reflect didn't work on it and Accelerator got sliced in two by Aleister’s self defense program that he embedded into Aiwass’ body, on the off chance it was in danger. Aiwass also had golden-white wings hidden under its hair. Accelerator brought out his black wings and tried to attack, but Aiwass only smiled and says that’s something from the Aeon of Osiris and that it was outdated and cannot possibly defeat itself, a being from from the Aeon of Horus. Their wings clashed and Accelerator got beaten in one blow. Accelerator then followed the AIM Field from the SISTERs and forcibly shutdown Misaka Network, since Aiwass had said Last Order was the core for its existence for now. While Aiwass was disappearing, Accelerator pulled out his handgun and shot its exposed triangular-prism core. After Accelerator shot the core, Aiwass was still present, with the additional defenses programmed in by Aleister. Aiwass said that it was such a pity before finally defeating Accelerator.

At the end, Aiwass is shown having a conversation with Aleister. Aiwass is motivated by the 'value' of doing something, while Aleister judges things by 'efficiency.' Aiwass also comments on the differences between Touma and Accelerator; Accelerator craved for the wholesomeness of being a 'hero' like Touma, to the point he declared himself evil since he cannot reach that level, while in reality, Touma is only doing whatever he felt was right and is labeled 'righteous' by other people impulsively.

Aiwass ends up asking Aleister if he envies 'heroes' like them, the three of them that stands up with their own two feet regardless what happens. One who follows his ideals no matter what (Kamijou Touma); one that tries hard to redeem himself (Accelerator); and someone who is never looked at by people, nor has any talent, but for the one person he loves, he’ll become a hero anyway (Hamazura Shiage).

Fiamma of the Right and the World War III Arc
Aiwass talks with Kazakiri Hyouka, telling her that Archangel Gabriel, or a better description is 'Misha Kruezhev' due to a mix-up in essence, is going to descend soon and then there will be many innocents dead, and Kazakiri should go and restrain Misha. Aiwass doesn't feel like going himself since that's no fun. Aiwass says himself can control the Misaka Network even without Last Order, since the SISTER clones have agreed to help, and he can expand the AIM field in Academy City all the way into Russia. Kazakiri agrees on one condition, that is for Aiwass to not go after Index. Aiwass replies Index will only be targeted if she interests him. Kazakiri then said if Aiwass does go after Index then she'll stop him, even if it means destroying them both. Aiwass smiled and then called her threat naive, since that statement just might perk his interest.

After World War 3 is over Kazakiri warned Aiwass that if it continues to toy with humans one day it might be destroyed by them. Aiwass merely replied that if the frail humans can one day reach their level then that would be interesting.

Abilities
Aiwass's powers cannot be described nor comprehended, however it was capable of making everyone in the vicinity (with the exception of Accelerator) lose their consciousness simply by appearing. Aiwass was also able to bypass Accelerator's vector shields while awakened, as if they were nonexistent. Being far above conventional Christian Angels, which are beings capable to laying waste to everything on Earth with the utmost ease, even one such as the Archangel Gabriel, "The Power of God," meaning that Aiwass is easily one of the strongest entities to appear thus far. It also needs a field with a lot of AIM to manifest itself.

Unlike Kazakiri Hyouka or other artificial angels, the physical form Aiwass currently has many other functions 'programmed' into itself, such as automatic self-defense and being able to continue to exist even if its core is destroyed. Also, Aiwass mentioned its current body even has a transformation function - though the readers were not shown what it can do before that was used to defeat Accelerator.

Trivia

 * Aiwass, Fuse=KAZAKIRI and AIM Burst have all displayed similar angelic features, such as a halo and wings of light.
 * Accelerator noted that Archangel Gabriel and Fuse=KAZAKIRI were "monsters", however they where much weaker than Aiwass who he could not even begin to think on how to defeat
