2, the second king of hell = = = Yellow-eyed devil (Azazel, few people know that he is Lucifer's assistant), the devil who killed the hero's mother.

3, the third king of hell = = = Korol, in the case of hell demon leaderless, defeated the opponent Lilith (the film did not mention the origin of Lilith, but it is actually one of the three female demons in hell).

Before Korol became the king of hell, in order to defeat Lilith, Korol had cooperated with the protagonists, each taking what he needed;

Korol became the Queen of Hell, which was equally cruel, but unlike the former King of Hell, he was better at management. Under his management, the demons were honest, but they still opposed the hero.

For example, before Lucifer, he was like a mafia leader, doing evil and leading the mafia all over the world;

The yellow-eyed demon is like the first master of the underworld except Lucifer, a lonely murderer, running around doing evil;

Korol, like a gangster, is not very strong in himself and has strong management ability under his opponent, but he can't get rid of the essence that he is a bad guy.
