As the oldest of his brothers, he’d really appreciate it.
He does admit sometimes it’s you causing havoc beside one of his brothers but the fact that you stepped up instead, he’d gladly appreciate it.
If you miss your siblings and wish to see them, he’d be okay with taking you back to the human world to visit them for a brief moment.
He understands missing a sibling. He’d miss his brothers if he were in your situation, although he’d never admit it.
If he’s also part of the mess (surprisingly) and you decide to take charge, he’d appreciate that you were able to calm him down and may take you somewhere to thank you.
Overall, I think he’d be the most impressed.
Probably the one that stirred up trouble.
He’d get scared at first, seeing you take the authority instead. You scolding him would probably be more painful compared to Lucifer’s physical punishments.
He’d feel kinda guilty afterwards, kind of embarrassed that he was the reason you brought your older siblings instincts out.
Would probably try to use you against his brothers, thinking you’re actually willing to go out and stick up for him trying to cause mischief
Actually likes when you difuse the situation, seeing you won’t let his brothers tie him up in the corridor again
He will feel bad afterwards and just cuddle you lol
According to him, Mammon kept messing with his Ruri-chan action figures.
Is surprised, but ultimately entertained, that you decided to step up to help calm the situation.
He’d probably take a video of you calming down his brothers and it’ll go viral in the devildom and get used as a meme.
Does feel very embarrassed if he was participating in the trouble with his brothers, but is relieved that you could calm down the situation.
He knows not to cross you now.
Would probably take you to one of his concerts as a sorry.
He is a bit surprised, a little taken back.
You sure have some balls seeing you’re just a human trying to calm a fight between ancient demons.
This man is the Avatar of Wrath™, if you manage to calm him down then you really did deserve being his friend.
Also he does try to control his temper, so if something or someone ticks him off, he’d go to you so he could calm himself. That or he’d hole himself in his room because if he goes on a rampage around you, well he doesn’t want another mini Lucifer (you) to lecture him
Honestly impressed by you. He now knows you have younger siblings and would ask to see pictures. You two would compare your siblings to each other and see who is more like whom.
If he’s part of the situation and he sees you interjecting, he’ll probably try to nicely ask you to leave if he’s getting too heated. But I also doubt he’d continue and instead go somewhere else with you so he can distract himself.
He’s the type to vent it out to you and see what you have to offer him. It wouldn’t take long before he begins to flirt with you again.
“MC you’re so sexy ahaha kiss me”
He does feel bad having you in a stressful situation just to difuse a quarrel between his brothers. So he’d take you to a spa to help you both to relax.
He does love his brothers, he would miss them as well if he were in your situation. Although he may not admit it. Just to help you, he’d listen to your stories about your siblings and may want to look at pictures.
Would call you “big sister/brother/sibling” to tease you.
Family is VERY important to him.
Seeing you become a peace maker for his siblings, his heart would skip a beat.
This mf is a big baby and he’s very much older and bigger than you, but he still considers you family or more and appreciates you more and more each time you do something with his brothers.
He’d make it up to you somehow. Be it going to a restaurant, going to a sporting event, or just going anywhere you’d want to, he’d be perfectly okay with that.
He just admires how you treat his brothers like their your brothers as well.
If he were one of the reasons a fight was caused, he’ll apologize. He’d never hurt you, and if he scared you he'd be sad.
Likes to talk about your siblings and asks to see pictures of them if you have any. He’d like to meet them and tell them they have an awesome older sibling to take care of them.
He is a bit frightened at first.
You know usually the youngest sibling usually has it easier more or less since they’re the “baby” but this mf basically killed you before.
Yes, he’s troublesome and he probably caused some mischief. He’d think he’d get away with you but instead you get onto him.
He really is interested in seeing your family and hearing stories about them as well. He missed his brothers when he was locked away in the attic, so he’d understand if you missed your younger siblings.
He does let you baby him now. Especially in front of his brothers, he wants to purposely get them jealous but would deny it.
Back to the miniature family fued, he tells you that it happens quite a lot and it isn’t that serious but seeing you calm down demons that can easily kill you at any moment at any time, he just lets you do your thing.
He does appreciate you care about them like you’d care for your own siblings. Even if he does find it annoying at times, being told what to do, he still does have a soft spot for it.
