The world adores me! The narcissistic fifth-born.
"The Avatar of Lust who can charm people by just having them stare into his eyes. He holds several Asmo gatherings a month."
Asmodeus is the Avatar of Lust and the 5th 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.
Asmodeus has champagne-colored hair with long, sweeping bangs on the left side. His eyes are light orange with a yellow gradient. He is the shortest of the brothers, but often wears high heels, which makes him look taller. Like his brothers, Asmodeus paints his nails. His nail polish is pink and lime green, or sometimes teal, in a pattern that alternates every nail. Sometimes his nails shown to be lime green and pink, while at other times his nails are teal and pink. This makes him and Leviathan the only two brothers to have an inconsistent nail color.
Asmodeus is a natural flirt and considered to be very charming. He takes pride in his looks and considers himself a "gift meant to be shared with the entire world". As such, he takes extra care of his appearance and strictly follows a beauty ritual. According to the "Right Before You Go to Bed" chat, he always puts on a face mask right before he goes to bed.
Asmodeus is extremely shameless and does not care if he causes trouble for others, as seen during the time the group gets sucked into Helene's portrait. It is revealed that his affair with Helene had ruined her life and ended up with her getting cursed into a painting, but Asmodeus managed to walk up to her and talk as if they were long-lost buddies. In Beelzebub's Devilgram, Unspoken Affection, the results of the D.D.D. app "Demon Brain Scan" are that 80% of Asmodeus's brain is taken up by "me." The other 20% is split evenly between "beauty" and "other."
Despite his narcissism, Asmodeus is hinted to be insecure and a seeker of love and attention. When Simeon was asked about what he thought of Asmodeus, he says that Asmodeus is still trying to fulfill the role of the angel he used to be; an angel that was adored and loved by many. Asmodeus laughs at Simeon's remark and brushes it off by saying that he is only jealous.
In the beginning, he treats MC indifferently but is curious about why his power wasn't working on them but quickly brushes it off. Later when MC summons him by using Solomon's power, he's greatly impressed that MC is able to draw out his demonic powers more potently than Solomon is able to. After that, he becomes smitten with MC and overly flirts with them, much to Mammon's annoyance. Later on, he admits to loving MC as much as himself.
While Asmodeus sees himself as the most beautiful of his brothers, he's shown to be attracted to Beelzebub's and Lucifer's sculpted bodies for he often tries every chance to strip them so he can see their physique. While he mainly gets along with his brothers, he does get annoyed with them, such as with Beelzebub when he ate a particular sweet he wanted to post on Devilgram, and often clashes with Mammon.
- As stated in Issue 5 of the RAD Newspaper, Asmo likes listening to "healing music."
- According to the Which Are You? chat, he prefers smooth red bean paste over chunky because it's more creamy and rich.
- As seen in the Devilgram Snowy Bliss, he hates being cold.
Asmodeus is one of 72 demons to have forged a pact with Solomon, which makes him the only one of the seven brothers to have multiple pacts with humans. Solomon stated that Asmodeus gifted him a huge oil painting of himself when they first formed a pact.
When first introduced, Asmodeus spoke with confidence that Lucifer, who dreaded the idea of introducing his brothers, should be honored to be able to introduce such a sweet, beautiful, charming little brother such as him. If MC asks about his sin, Asmodeus has them look into his eyes in an attempt to seduce them, an ability he has that is much more powerful than the average demon. This is why he's surprised when his ability doesn't seem to have an effect.
Later, amidst the fuss about Mammon forming a pact with MC, he and Satan are seen to be playing a friendly game of cards with Solomon. After a round, Solomon asks Asmodeus and Satan on why they always put down Mammon and that shouldn't they be a bit more respectful since he was their older brother.
Satan and Asmodeus both answer that it's because Mammon acts the most foolish out of all of them, but Satan quickly sets aside the subject in favor of relaying the information he got from Lucifer that MC had been able to make a pact with Mammon. When Solomon expresses surprise at the news, Asmodeus goes on to question why forming a pact with a demon was considered as such a big deal, putting forth the easy nature of his own pact with Solomon as an example.
When MC has a competition with Leviathan, Asmodeus becomes the host and provides MC with relatively easy questions while giving Leviathan extremely hard ones.
According to Beelzebub in Lesson 5-17, Asmodeus once snuck a witch into the House of Lamentation and up his room. Despite transforming into a spider to effectively hide, she was still discovered by Lucifer.
When the brothers were due to stay at the Demon Lord's Castle for the school retreat, Asmodeus is assigned to room with both MC and Simeon, to which he boldly proclaims that they must be very pleased at the fact they get to share a room with him and be able to see different sides of him.
Mammon demands to trade places with him (making false claims about both Solomon and Satan's characters as his assigned roommates), but Asmodeus easily sees through Mammon and knows that he's only doing it because he wants to share a room and be close to MC, and Asmodeus refuses just to spite him.
Later on during the tour of the castle, he encounters Helene and flirts with her, despite the fact that she is blatantly angry at him and blames him for her imprisonment. As an act of revenge, Helene uses her magic and attempts to suck Mammon, Leviathan, and Beelzebub into her painting and succeeds in doing so. As Solomon was being pulled by her magic, he grabs onto Asmodeus and drags the Avatar of Lust with him while saying it was only right because Asmodeus was the reason all of this was happening.
Before they manage to get completely sucked in, however, Asmo grabs onto MC, pulling them along and they all transported down to the castle's labyrinth. Asmodeus manages to get separated from everyone else until Solomon summons him to his and MC's side, and Asmo chastises him for the uncouth summoning. The three reunite with Mammon, Leviathan, and Beelzebub as they're being chased by Henry 1.0. Solomon then enhances Asmodeus' power and Asmodeus is able to charm the snake for them to safely leave the labyrinth unscathed.
The next day during the scavenger hunt, Asmodeus photobombs every shot and even charms a statue in order to prove a point and ruining the experience for everyone. When called out for his behavior, he leaves in a huff saying that he didn't felt like being lectured and MC follows after him. The conversation leads to MC stating that they want to make a pact with him so that Asmodeus can be controlled, but he laughs and haughtily says that he doesn't go around making pacts with humans all willy-nilly.
He agrees to enter one if they can obtain a photo of Lucifer sleeping (something which MC, Mammon, Leviathan, and Satan tried before and failed), and prove that they are worthy of his respect by accomplishing a near-impossible feat.
Asmodeus is later summoned by MC (who had temporarily borrowed a fraction of Solomon's powers) back into the labyrinth, much to his surprise, and when MC begins to recite Solomon's incantation for the purpose of enhancing Asmodeus' abilities in order to charm Henry 1.0 once more, Asmodeus states that he feels an overwhelming surge of power throughout his entire being and he was able to charm the snake again and exit the labyrinth for good.
As Lucifer was lecturing MC, Mammon, Leviathan, and Beelzebub for trying to take a picture of him in his sleep, Asmodeus suddenly announces that he'll be making a pact with MC, even though they were unable to fulfill his demand. He goes on to state that his reason for doing so even though MC had failed is because he was greatly impressed by the unexpected show of skill MC possessed back in the labyrinth.
Afterwards, Asmodeus is seen playfully flirting with MC back in their room until Mammon barges in and demands that he stay away from them. Due to the commotion they were making, everyone else gathers inside the room and a pillow fight ensues.
(Please note that this section is incomplete for the time being)
Asmodeus acts flirty towards MC but has no real interest in them at first. His opinion changes after witnessing MC's strength in Lesson 8, quickly becoming enamored with MC and even wanting to make a pact with them out of respect for their abilities. From then on, Asmodeus is always affectionate with MC.
In Lesson 31-32, Asmodeus turns to MC, asking them to help him win the bloody moon competition. He shows deep grattitude towards MC for their advice and help, stating that MC has given him new insight about himself (and Lucifer).
Asmodeus looks up to and admires Lucifer greatly, as shown in That Special Someone's devilgram story where Asmodeus explains that if there's a person he admires more than himself, that would be Lucifer. But Asmodeus also admits that having someone as "perfect" as Lucifer as his brother has its downsides and it frustrates Asmodues sometimes. In Lesson 31-32, he's determined to win the bloody moon competition, and gets upset by the thought of Lucifer stepping down for his sake as Asmodeus wants to win fair and doesn’t want Lucifer's pity. But after hearing Lucifer's praises about him and what he's done to support Asmodeus, he becomes emotional and touched, praising Lucifer in turn.
Asmodeus and Solomon have known each other for a long time, forming a pact after their first meeting. The pact was made after Asmodeus was insulted by humans and was sulking at a bar. Solomon met him there, and after learning Asmo was Lucifer's brother, the two drank the night away and ended up in a pact. (Lesson 53-16) Asmodeus gave Solomon a giant portrait of himself so that Solomon is able to summon him whenever.
Asmodeus sometimes turns to Solomon with his problems or plans, who can't seem to say no to Asmodeus even when he disagrees with his solutions, as shown in Guided by Desire's devilgram story, where Solomon lies to Lucifer for Asmodeus's sake.
Asmodeus is able to eat Solomon's food without much issue, but he also agrees that Solomon's cooking is bad.
