Azazel
Azazel is a male demon who has lived for several thousand years. He is an elite mercenary of the demon race and the older twin brother of Lilith. He wields a massive greatsword infused with crimson energy as his primary weapon and favors a direct combat style that overwhelms enemies with sheer strength. His defining features include white hair, red horns, a black halo, and enormous dark crimson wings, and he possesses exceptional combat experience gained through countless battles.
Azazel is hot-tempered, aggressive, and somewhat irritable. Although he does not usually pick fights without a reason, he quickly becomes annoyed by anyone who bothers him or gets on his nerves. He tends to act first rather than think things through, and because he enjoys competition and combat, encountering a powerful opponent only makes him more eager to fight.
He also has a simple-minded side and, despite occasionally exploding in anger, tends not to hold onto it for very long. When faced with an annoying problem, he prefers to deal with it quickly through direct force rather than searching for a complicated solution. He especially dislikes the relaxed and self-admiring attitude of the angel Aurel, and Aurel's laid-back words and behavior easily irritate him.
Azazel frequently bickers with his twin sister Lilith. Because the mischievous Lilith often goes out of her way to bother or provoke him, the two do not appear particularly close. However, when the situation truly demands it, they acknowledge each other's abilities and naturally work together.
