Beelzebub

"What time is dinner? The always-famished sixth-born."

"'A growing demon who is always eating something. He loves his younger twin brother Belphegor.'"

Beelzebub is the Avatar of Gluttony and is the 6th oldest 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
Beelzebub has messy orange hair and blue-violet eyes with a pink gradient, similar to his twin, Belphegor, and is the tallest of all the brothers. Despite his everlasting tendency to eat, he has ripped muscles and abs, due to him working out a lot. Like all the brothers, he wears nail polish, but his comes in the orange variant.

Personality
Beelzebub, being the Avatar of Gluttony, is always hungry and gluttonous. He fills most of his bag with food during travelling or stays in either places, as seen in Lesson 7-1 when Mammon criticizes his luggage size. He is easily bargained with food and will do any favors for those who promise to pay him with food. Despite his tremendous food intake, Beelzebub manages to maintain a sculpted body figure through exercise. His brothers tend to fawn over his figure.

He is emotionally mature and wants the best for his brothers. He dreams of a world where he can live happily without a care in the world with his siblings. He has a childlike innocence and is affectionate, hugging Belphegor as much as he can and asking if he could hold MC's hand until he falls asleep.

Naive and childlike as he can be, Beelzebub holds tremendous guilt and blames himself for the death of their youngest sister, Lilith. He thinks that Belphegor blames him for Lilith' death and wonders if Belphegor could ever forgive him. He even asks MC as to whom they would save if they had to face the same choice.

Main Story Normal
Beelzebub, who was being introduced at the start of the game had a grumpy look on his face. This is because he was'' hungry. ''

When MC asks him on the whereabouts of their 7thundefinedbrother, Beelzebub warned to MC to never mention him in front of Lucifer. Beelzebub further added that he won’t say anything for the reason that Lucifer will yell at him nor will his brothers. With a sad look on his face, he claims injustice that even though he is their brother, they have to treat him like he doesn’t exist.

[Missing details on Lesson 3, please add!]

One day, Mammon texted MC commenting on how he was hungry and asked MC to come down to the kitchen while implying that it is not because of his fear of Lucifer catching him alone that he asked MC to come. In the kitchen, Mammon talked MC into eating Beelzebub’s custard which had a note clearly stating “''Property of Beelzebub. Eat it, you die.''” To their surprise, Beelzebub caught them in the act and flew into a rage, transforming into his demon form.

After being lectured for hours by Lucifer on the incident that had occurred, MC, who had their room totally destroyed due to Beelzebub’s attacks, was told by Lucifer to sleep in Beelzebub’s room until repairs. Beelzebub who could not disagree in the matter had no choice but to accept Lucifer’s demand. In his room, Beelzebub tells MC to not sleep on the bed on the right side of the room for the fact that it was his twin brother’s bed. Beelzebub continued as he tells MC to sleep on his bed instead as he will sleep on the couch. When asked about his twin brother, Belphegor, Beelzebub stated that he was in the human world as an exchange student despite being opposed to the idea in the first place. As twins, he implied that the two did not look alike and were only considered as twins solely because their father had made them at the same time. Beelzebub mentions that they had a little sister with the name of Lilith and that the three of them got along very well with each other. Due to MC’s suspicions, they asked Beelzebub to show a picture of Belphegor thus confirming the truth that the person in the attic was indeed Belphegor.

During MC and Beelzebub’s search for Luke, Beelzebub talks about a dollhouse that is a replica of the House of Lamentation and, with the help of MC, uses it to find a secret room - a replica of Lilith’s room from the Celestial Realm. MC questions Beelzebub about Lilith and Beelzebub opens up about his history with them and the Great Celestial War. He mentions that he had a choice in saving her or Belphegor and, as he chose to save Belphegor, he blames himself for her death, despite many telling him that it wasn’t his fault. Beelzebub believes Belphegor blames him for Lilith’s death. Later, when Lucifer is going to kill Luke, he confronts Beelzebub for bringing in and hiding Luke. Lucifer decides he will attack Beelzebub as well.

After Lucifer's apology to MC, a meeting convenes about Diavolo's plan to have an exchange party at the Demon Lord’s Castle wherein humans, angels, and demons will have a group exchange. During the meeting, Beelzebub seems to be unable to focus on anything except for mentions of food and the dinner party. MC informs an imprisoned Belphegor about the exchange party, but he mentions that the important thing is if MC had only made a pact with Beelzebub. Once at the Demon Lord’s Castle, in a room where almost all the brothers are present, it is seen that Asmodeus and Mammon are fighting, with everyone else around them bothered by the racket, all except for an oblivious Beelzebub who comments about how shadow swine offal they served at the castle was of good taste.
