Aleister Crowley/Personality and Relationships

Personality
Aleister Crowley exudes an aura of levelheadedness, and most often talks in an incredibly cryptic manner. The man's personality is that of one who doesn't show many overt expressions, but still possesses emotions, like smiling during interesting events, such as when he questioned on what existence the Imagine Breaker would prove. He is shown to be a mastermind behind many things, manipulating several coincidences for Kamijou Touma and Accelerator, key cores in his plans, to fall into, like allowing Touma to be used by Stiyl Magnus, or Accelerator forcibly being inputted with the numerical settings of the AIM diffusion fields. He has many plans running parallel and seemingly abandoning one plan in favor of another if it fails; though the act of doing so, with the apparent disbanding of one enabling the execution of another or even the original purpose of the plan benefiting from its discontinuation, could still be a facade. According to Musujime Awaki, his plans are probably beyond what anyone can think of, and in his eyes, even the planet might only be a resource for use and discarding.

However, Aiwass says that he is not a perfect human, and that the plans that he has woven are falling apart in the seams, such as the continued existence of Hamazura Shiage. He has also shown anger and hesitation, as with what happened to Leivinia Birdway, having a few strands of her hair cut-off after taunting Aleister of the unraveling of his plans. Aleister has conflicting desires in his heart, making him a valid target for World Rejecter.

According to Kihara Noukan, Aleister has a habit of trying to sound rational when he's handling everything through emotion. In the past, despite having been a coldheart pragmatist, rejecting human emotion as impure and cursing the imperfections of mankind, he had gone on passionate rampages, married a woman and had a daughter, and kept a journal. On the day his daughter died, he apparently left a tear stain in his journal, and when given the opportunity to become a Magic God, rejected it and chose to remain as a human in the same realm as his family.

Aleister bears a thorough hatred for gods, having come to look down on the god who created the world so easily fooled and unable to punish liars at a young age. His wish to find the rules and answers that god could not and make the world a better place is what started him down his path, and likely influenced his later work. The Magic Gods' involvement in his daughter's death only added to this hatred.

Due to the many setbacks in his life, Aleister is quite aware that things often won't work out the way he wants, and as such set up his plan so that everything would converge on a single path not matter what crises befall him. Despite setting up his plan to be a perfect one, he doesn't wholeheartedly wish for it to be so and has cursed it at least once, thinking it to be little different from what the Magic Gods do.

Family
Aleister's parents, who were Christian and held influential positions in the town he lived in, considered the young Aleister stupid for his lack of belief, refusing to listen or understand him. Rather than protecting or caring for the boy as a parent should, they were more focused on ensuring that he acted "proper", sending him to a strict boarding school in the belief that it would place in him the strict spirit and understanding of God's teachings they desired. Aleister held considerable contempt and scorn for his parents, whom he saw, like many of the other people in his childhood, as proclaiming themselves believers and righteous yet acting foolish and disgracefully.

Lilith Crowley
Lilith isn't keen on her overly long full name and did attack Aleister for appearing in the body of a young girl when they reunited, but she does care for her father, reaching out to the hesitant Aleister when her strength ran out. Aleister loved his first daughter and favoured her over his other children, giving her a long, meaningful name that he read from the stars. It was Lilith's foretold early death that led him to destroy the Golden Dawn and seek the destruction of magic, as well as his hatred of the world after it came to pass. His miraculous reunion with his daughter reignited something within him which had been frozen for ages. At some times when Lilith reached out her small hand to Aleister, he has shown hesitation in reaching out with his own, perhaps not wanting to her or feeling he didn't have the right to take her hand.

Lola Zala Crowley
While Aleister didn't favour Lola as much as he did Lilith and was estranged from her after taking his anger out on Rose after Lilith's death, he still cares for her as a father. On learning how Coronzon supposedly possessed her and hearing how her supposed last words as she was being taken over were crying out to her father to help her, he made the demon's complete eradication and his daughter's rescue his top priority.

Coronzon
Coronzon doesn't have a particularly high view of Aleister, looking down on him and mocking him for his failures. After ambushing Aleister, the demon took great pleasure in supposedly using his daughter's body to trample on the father's dignity and taunting him with her last words.

Aleister had displayed hostility towards Lola Stuart before she revealed herself as Coronzon, but after learning what the demon had supposedly done to his daughter, Aleister immediately focused his efforts towards its complete eradication.
