Belphegor

"Could too much love breed rebellion? The catnapping seventh-born."

"'The youngest, cheekiest, and most cunning of the demon brothers. Until a certain incident took placce, he respected Lucifer the most among his brothers.'"

Belphegor is the Avatar of Sloth and is the youngest and 7th sibling among the seven demon brothers. He is one of the main characters in Obey Me! One Master to Rule Them All that is involved in the intimacy system of the game; therefore, users can interact and raise their relationship with him.

Appearance
Belphegor has dark bluish grey, white-tipped hair with long bangs that cover his right eye, and violet eyes with a pink gradient like his twin Beelzebub. He's among the shortest of brothers, at least compared to Beelzebub.

Like his brothers, he wears nail polish, but in a cyan colored variety.

Personality
Napping and constantly sleepy, Belphegor is the second youngest of the demon brothers but ranked as seventh due to his powers. He is a clever trickster and liar and had a strong hatred towards humans, believing them to be the cause of Lilith's death. But Belphegor never hated the human world, he loves it too much to ever come to hate it. What he truly hated was Lilith's fate. Unable to accept the fact that he was the one who left her to die, he grew to “hate” humans because he had no other way to express his anger. After hearing that Lilith did survive and had a family, leading to MC, his hatred for humanity dissipated and was able to let go of his sister.

He sometimes has a brisk tempter, but he's also proactive, efficient, sensible, and mellow. He isn't particularly sociable but still wants to cuddle and take naps with MC. He also lies about the fact that he doesn't like to be pet. He isn't the type to say sorry or accepts "a sorry" from others, for he sees an action or gesture as an act of forgiveness instead of words. He has expressed regret in "killing" MC and accepts and expects MC to not forgive him (if they chose so).

Belphegor is rebellious, as he does not care for any higher authorities, especially Diavolo and his whims. He is naturally manipulative and a great actor, posing to MC as a human prisoner of Lucifer when they first met. After he's been freed from the attic, he shows sadistic tendencies and he's delighted to see the broken faces of his brothers, mainly Lucifer. Since he's been locked up for a long time, it's possible it made him lose his mind, which resulted in this behavior as otherwise, he hasn't acted this way at later points in the story.

Out of all his brothers, he's closest with his twin Beelzebub where they share a telepathic link. He used to be quite fond of Lucifer but quickly despised him after he swore his loyalty to Diavolo, however, after MC helped amended their relationship, he doesn't outright hate him but does find him suffocating. He and Satan had formed an alliance where they'll prank Lucifer or make his life miserable in anyway they can.

Background
Belphegor was born in the Celestial Realm as an angel, along with his brothers and younger sister Lilith. He, Beelzebub, and Lilith were all very close. He had loved humans and was always sneaking in the human world, which led Lilith to become interested as well.

After Lilith fell in love with a human, she was severely punished for trying to cure his illness, which sparked a war with all the brothers fighting against their father. During the war, he and Lilith were nearly killed until he was saved by Beelzebub but Lilith was mortally wounded.

Many years after settling in at the Devildom, Diavolo proposed an exchange program with the other worlds. While the other student council members were for it, Belphegor was strongly against it. The night, he pleaded with Lucifer to make Diavolo change his mind but Lucifer refused. When Belphegor reminded him about Lilith, Lucifer remarked on what she had to do with Diavolo’s goal. Lucifer’s dismissal of their sister sent Belphegor into a rage and attack his brother, only to be subdued and imprisoned in the attic until he changed his mind.

Main Story Normal
Belphegor, being portrayed as a voice in the early parts of the game, continuously calls out to MC for help from the attic where he is locked up but is unable to proceed because Lucifer stops them and then makes a veiled threat.

MC is able to distract Lucifer with the TSL soundtrack, obtained after making a pact with Leviathan, and heads toward the attic as Belphegor continuously guide them using his voice. When MC asked about his identity, Belphegor lies that he's a human just like them. He continues the conversation by saying a demon was the one who locked him up there, that demon, being Lucifer. Belphegor then pleads MC to help him.

The door cannot be opened by either of them for the reason being that it is sealed with very powerful magic. With that said, Belphegor suggests MC make pacts with all of the demon brothers to gain their consent which will then open the door. With the fact that MC had already made pacts with Mammon and Leviathan, Belphegor suggests Beelzebub be the next target.

After MC talks to Beelzebub and realizes that the missing brother is Belphegor, they confront him and he implies that he's just teasing and that humans are a foolish lot. He then explains that he wants to have a proper talk with Lucifer, but MC is hesitant to trust him since he lied to them.

After clearing their thoughts, MC comes back after a day and agrees to help him make pacts with his brothers and set him free. Belphegor then warns them to never speak to his brothers of his situation.

After making a pact with Beelzebub, Belphegor is impressed by how far MC‘s come along and they discuss the exchange party at the Demon Lord’s Castle. MC also tells him about what Lucifer said to them about a spell that bars demons from entering the attic, but angels or humans are able to pass through. They also tell him that Lucifer is convinced that MC can’t see him or this room. Belphegor sees this as good news and wonders why an ordinary human was picked for the exchange program. He then tells MC to find out why they were chosen while staying at the castle.
