Anyways, here's a list of the demon brothers and their 'not so nice attitude' A warning that this will include spoilers from Devilgrams which I don't own MOST of them.
Let's start with our favourite goof ball: Mammon
- He has threaten to sell your stuff at the beginning of the game. He even wanted to sell your blood in the Vampire event.
- He said that you should die if he was unable to save you at any given point.
- He indirectly had Beel destroyed your bedroom and even forced you to eat Beel's custard
- About 50% of the time he roped you in his scam to steal stuff and even tried to put the blame on you.
- He had a picture taken with Satan about strangling a bunch of Incubis
- The worst he ever did was almost killing you for knowing a spoiler before him.
- He released a deadly monster in the human world causing chaos
- Satan had threaten to chop you up limb by limb and was about to kill you when you refuse to make a pact with him
- He almost killed two parents Infront of a child and was filled with excitement seeing them begging for mercy.
- He almost ate you. Literally
- Had your room destroyed after he found out his custard was eaten by either you or Mammon
- He admitted to you that he was thinking of eating you so that you won't have to leave
- He wanted to eat you in both the Vampire event and the Paws and Claws event
- He literally kills you. Like. He successfully kills you.
- The only demon I don't really like and I can't believe MC forgives him easily.
- It is confirmed by the Devs he is a manipulative yandere.
- According to the actual translation 'The cat napping seventh born' was actually 'The yandere seventh born'
- He caused a war broke out and a woman trapped in a picture forever
- He indirectly caused us to be eaten or killed by Henry 1.0 and doesn't even feel remorsed about it
- He said that he'll cut you open to see your insides when he found out the secret between you and Belphie
- That one demon that everyone got so dramatic about.
- Maybe because in all of the event modes, we always ends up with him.
- He had tried to kill you twice. One when you protect Luke or Beel and two, when you told him you met Belphie
- Kinda said mean things like 'A lowly human' and stuff
- Almost crushed your hand when he forced you to dance with him.
- Let's you get sucked into the labyrinth by Helena.
- Drama begans in Vampire event.
- Devs tones him down by not making him the main boi in the events onwards.
- His Idol Devilgram card had him saying 'Will you consent to be my partner?'
- Please don't hate Lucifer. He's a good boi I swear.
