Sibling relationships
Some headcanon about the brothers interactions and relationship.
Lucifer is well aware of Levi's social anxiety, so much that he was the one who intervened to allow him to study from home, speaking personally with Diavolo. For that reason, he can't help but spoil him.
Lucifer also greatly appreciates his passion, which is why he makes an effort to take an interest in his tastes, the new anime, manga, or games he’s passionate about, so he can share them with him and, in that way, try to help him open up more to the world and not withdraw so much into himself.
Mammon spoils Asmo; despite their differences, he’s the one who lands him the best shoots and opportunities in the modeling world, plus he always promotes Asmo’s products and frequently wears them. He’s the first to brag about his achievements.
The demon knows that Asmo is pretending, that he’s been pretending for a long time, so he makes sure to keep him busy, take him out partying, or just listen to him. It’s not uncommon for him to deal with obsessive fans or stalkers without Asmo ever noticing.
Leviathan fully understands Satan’s hyperfixations, so he’s Satan’s best ally when it comes to getting files, books, or other strange things. He’s the only one who can talk for hours on end with the fourth-born, and he often lets Satan “interrupt” his game nights to discuss a new interest.
Levi understands Satan’s frustration, imposter syndrome, and the helplessness of having someone dismiss your feelings. So often, when Satan has a fit of rage, Levi gives him his precious loyalty cards for cat cafes, or even accompanies him to shelters to volunteer with the kitties.
Asmodeus is always the first to go to Beel’s games, cheering him on with all his might and celebrating his victories as if they were his own. He promises to promote restaurants so they’ll continue to let Beel eat there. Many of his collaborations with restaurants are for this reason.
Asmo understands the pressure Beel feels from believing he must protect everyone, and the disappointment of having let his loved ones down. That’s why Asmo always gives him hugs, because, even if he doesn’t ask for it, Beel can feel his family’s presence.
Whenever Satan comes across a new or innovative blanket, pillow, or other sleep-related item, he buys it for Belphie. He also often uses his connections to stay informed about astrological events in the Devildom, and whenever he’s invited to these events, he always brings his brother along.
Satan knows that Belphie is suffering from deep depression. So he stays by his side, being with him without saying a word, simply being there for him whenever he needs it, without pressuring him, without forcing him to see the bright side, just there in case he ever wants to talk.
Beelzebub always tries to make sure Lucifer has some kind of snack in his study, bedroom, or RAD desk. He always tries to remind his older brother to eat, indirectly, for example by reminding him to buy certain things or suddenly deciding to make his brother's favorite meal.
He also takes care of putting him to bed on many of his nighttime expeditions. Beel tries to help his brother from the shadows, because he knows Lucifer doesn't want to depend on anyone, he takes care of him secretly so his pride isn't hurt.
Belphegor always makes sure Mammon has sweet dreams; despite how the younger brother acts, he knows how often his older brother has nightmares. Sometimes, he even uses them to persuade or scare off witches who are after his brother.
Belphie knows that Mammon can be many things, but above all, he cares deeply for them. So he shows just what a great older brother he is by acting like the younger brother from time to time. He knows Mammon loves it. And even if he doesn’t say so, he brags a lot about his accomplishments to other demons.
Mc always smiled when they heard about these situations, because there was nothing more adorable than seeing one of the brothers look out for the other.

I wanted to explore the relationships between the siblings a little more; despite everything, all the problems, all the conflicts, they all care deeply about their family. And even though their relationship was strained for years, they're still siblings.
Thank you for reading 🩷
