when it's time for mc to return to their original timeline how do you think the [nightbringer] characters would react if mc told them that they were from future and it's time for them to go back to the present timeline and that they'd meet them then
The common room was silent— so silent, it sounded like the entire Devildom was sleeping all at once. There was tension so thick you could cut it by just swiping at the air- there were eleven pairs of eyes trained onto Mc; the single tear that dripped down their face was like a harsh shock wave.
"I'm sorry...but I have to leave- I have to go back to my timeline now..I'll see you again when I return, okay? I promise."
Lucifer is absolutely flabbergasted, red eyes wide as he scanned your face for any signs of humor, but you weren’t joking. His hands trembled uncharacteristically, fingers twitching as he stretched his arm out to try and grab at you; "What do you mean you have to go? Don't...your place is here, with us, you can't leave- what the hell do you mean you'll see me 'when you return', I'm me! I'm right here! Don't go-!"
Mammon doesn't fully process your words, only really catching the part where you said you had to leave. He feels nauseous and scared as he immediately begins to stammer and stumble over to you, grabbing your hand and pulling you closer so he can feel that you’re still there; "Y-you can't leave! Why would you want to leave- your home is here, you belong with us- with me- I'm right here, where are you going? Don't leave me behind! I-I need you! Please!"
Levi instantly has tears in his eyes, too preoccupied with watching you start moving away from him to realize you said you’d see him again. His tail whips out to circle your waist, arms frantically grabbing at you as he cries; "W-w-wait-! D-don't go, don't leave...did I do s-something- a-are you leaving because of m-me? I-I'll fix it, I p-promise, just please don't go..."
Satan's first instinct is to get angry- to throw a fit and throw anything in reach and scream and lash out, but he just stands there staring at you. He understands the concept of time travel and other timelines- he's read all about it- and essentially knows that he'll see you in less than a minute once you go back, and yet...; "Leaving...? You're leaving? I- I don't...I don't want you to go..don't-...just..Mc, please."
Asmo hears everything you're saying, but he just doesn't understand! He practically curls his whole body around you as he stutters through his denial, trying so hard not to cry because it would ruin his makeup; "What do you mean you're leaving, hon? Time travel is nonsense..you belong here, with us! Y-you're not actually going to leave me, right? Not me...don't leave me.."
Beel immediately panics as his thoughts run rampant about losing you and never getting to see you again, despite you assuring him that you'd see him very soon- he can't lose someone close to him again, not you- and the way he grabs onto you shows his desperation; "No! I-I mean...no, you can't leave us- why would you leave us? I thought you were at home here, with us, please...I can't lose you, too..."
Belphie, like his twin, is panicking- but he's in a hysterical panic. He breaks down into sobs and apologies right at your feet- apologizing for any time he was snippy with you and especially the time he got so mad he almost hurt you after finding out you were human- he's so sorry, just..don't leave-!; "No, no, no! You can't! You can't leave us, please, don't leave, I'm sorry! I'm sorry for everything I've done wrong to you- just don't leave me! Please, don't leave me..."
Diavolo understands the concept of what you're saying, though it's still hard for him to grasp the fact that you're leaving to go back to a different him...why couldn't you just stay with him in this 'timeline'? Didn't...didn't you still like him either way?; "What...what? Mc, I don't understand...just stay. Here. With- with me, with us, I don't...why must you go back? Don't you like it here?"
Barbatos shouldn't be worried. He knows exactly what you're talking about and what you mean by 'see you again when I return' and yet he can't help but feel at a loss, torn between letting you just walk away or trying to stop you- he doesn't want you to go back to future him...he wants you here with this him; "I...wait, Mc..don't-...don't go back. Stay, please..I know I'll remember the time we spent together here when you return, but I...I don't want to let you go.."
Simeon is in an odd state between panicked and calm. One on hand, he trusts you. If you say you promise you'll see him again- whatever that means- he believes you. But on the other hand, he's already lost so much in life and he can't possibly bear to lose you too, so he grabs you and holds on tightly; "Go? What do you mean 'go'? I...Mc...I don't want to let you go..I don't want you to leave- please stay...with us. With me."
Luke's confusion dances across his face as he latches onto your waist, firing a thousand questions at once, as fast as he can speak them; "What do you mean you're leaving? How can you see me when you 'return'- what does that even mean?! I'm the only me...and I'm right here- where...where are you going?! Don't leave me! I don't want you to go!"
bonus :
Solomon is there to wrap his arms around your waist tightly for comfort, keeping the others from coming too close; he can't let them take you away from him- won't let them convince you to stay. Your place is in your own timeline, with the present versions of them, with him. He promised he'd bring you back home with him and no one is going to stop him; "Come on, Mc...let's go. We need to go- this is what we've been working towards remember? You'll see them in less than a second once we go through the portal. I'm here with you, I'm not ever going to leave your side. You trust me don't you? Let's go home. Together."
Been a minute since I've done something like this for the brothers!
I'm just gonna list them without explanation cause I can't think of anything right now, but if y'all want full headcannons for why I think this, lemme know.
Lucifer - On the side of the neck, high up enough that it's visible above a turtle-neck or something.
Mammon - Right over the heart. About the size of your heart, too.
Leviathan - Covers your entire freaking stomach. There's an empty space on the mark that doesn't cover your belly button and it's kinda cool.
Satan - All across your back. Freaking huge. Biggest mark out of all the brothers.
Asmodeus - I'm sorry, but I can't help it. His is right above your genitals. Like, the bottom ends right before your pussy/dick.
Beelzebub and Belphegor - They both have their marks on your hands, Beel's on one and Belphie's on the other. They're on the back of your hands, not your palms.
I thought of this during a midnight YouTube Short marathon, so..... yeah.
✗ is your biggest supporter and will show you off to all of his friends, especially honey.
✗ will be very clingy, but also will respect your boundaries. if you’re not in the mood for a hug, just tell him and he will back off, (he’ll probably ask you if anything is wrong).
✗ is very sensitive to your emotions, and will immediately notice if anything if wrong with you, even if you are a master liar. remember, uno is extremely perceptive in canon, so he probably knows all your habits and tells for when you’re lying. he won’t force you to tell him, but will remind you that he’s there if you ever need to talk about anything.
✗ he doesn’t really know how to fight, but he can definitely throw a solid punch, so he’ll try his best to protect you.
✗ will talk to you for hours on end about everything he loves about you, and will definitely tease you if you get flustered by it.
✗ is the type that will order for you at a restaurant if you’re feeling anxious, although he will sometimes make you do it, since he also wants to push you to get over your fears. will take you away from a large group if you’re starting to panic, and will help calm you down. overall, he is very protective of you, and wants to make sure that you are comfortable.
✗ he’s also great with an extroverted s/o, since he is a fellow extrovert. the two of you will loudly joke around and gang up on honey in the gameroom, challenging him to a game of darts. you’ll also probably pull pranks on jyugo, rock and nico a lot, and get chased around by hajime whenever you escape.
✗ almost all of your dates will probably be in his game room. he’ll challenge you to any games there are, and he’ll teach you all his tips and tricks that he uses when he’s gambling. Sometimes though, he’ll ask jyugo to let you guys out so you can go to the balcony and hang out for some alone time. uno loves being with his friends, but sometimes he just wants to be alone with you <3
✗ he is all about pda, but only if you’re comfortable with it. he doesn’t really care if anybody else teases the two of you for it, because have you seen my girlfriend? she’s the hottest girl on the planet!! will sometimes kiss the top of your hand just to make you flustered, but will mostly go for kisses on your temple.
✗ basically, he will just give you a lot of kisses everywhere. fingertip kisses, cheek kisses, temple kisses, all of them!!
✗ will sometimes place his hat on you because he thinks you look cute with it on <3
✗ after he won hyakunin isshu: “(y/n), i was definitely handsome out there, right? more handsome than those other guys, right?” please give him your affirmation, you will wound him if you say no.
✗ will give the best cuddles ever!! he’s a very affectionate person by nature, so expect to have him next to you the entire night whenever you guys are sleeping, especially during the winter, and especially if you get cold. uno will be your personal heater.
✗ he’ll let you brush out his hair and braid it in the morning; he finds the feeling very soothing. If you have longer hair, expect for him to braid your hair so that you guys can match.
✗ he would never let anybody else except you use his face masks. skincare is very important to him, so he wants to make sure that your skin is nice too, (especially if you’re insecure about it).
