Mammon

At first, he’s confused—your scent, your energy—it’s all different but familiar.

He grabs your shoulders and shakes you, asking if it’s really you.

Once you confirm it, he bursts into tears in the middle of the street, hugging you so tight you can barely breathe.

He insists you’re still his human, demon or not.

Now refuses to leave your side—if you’re a demon, you’re gonna be his partner in crime forever.

Leviathan

Lowkey panics because you’re not human anymore—what if you don’t like anime or games now??

You have to reassure him that yes, you’re still you, just with sharper teeth.

Once he calms down, he gets giddy about all the “demon perks” you can now enjoy with him.

Starts making fanart of “MC the Demon Lord’s Lover” and hangs it in his room.

If anyone insults your transformation, they’ll be on the receiving end of his tail and magic.

Satan

The curiosity overwhelms him—he studies every change in your aura, your abilities, your eyes.

His hands are trembling when he touches your cheek for the first time after your rebirth.

Angry at the world for taking you away, but even angrier at himself for not protecting you.

Swears to teach you every trick in the demon book so no one can ever overpower you again.

When you smile at him, calling him “my favorite demon,” his heart aches in the best way.

Asmodeus

He cries on the spot—not because you’re a demon, but because you’re beautiful.

Your new form has him swooning, taking hundreds of pictures, insisting the two of you need a photoshoot.

Says you’ve “leveled up” into his perfect match.

Keeps holding your hand like he’s scared you’ll vanish again.

Throws you a “Welcome to Demonhood” party that lasts all night.

Beelzebub

The second he sees you, he drops all the food in his hands and runs to you.

Hugs you so tightly you lift off the ground.

Quietly says, “You’re back. That’s all that matters.”

Doesn’t care if you’re human, demon, or something else—you’re you.

From now on, he will protect you the way he protects Belphie—without question.

Belphegor

At first, he can’t believe it—it feels like a dream.

Guilt hits him all over again for every moment he ever took you for granted.

Stays up all night just watching you breathe, terrified you’ll vanish.

When you joke about joining him in his naps “forever,” he smirks but there’s relief in his eyes.

Holds your hand whenever he sleeps now—he’s not letting you go ever again.

Diavolo

Beams when he sees you, though his smile hides deep relief.

Says you’re living proof that death isn’t the end—and that the Devildom is now your home forever.

Assigns you a special place in the royal court immediately.

Insists on personally training you in demonic etiquette and power control.

Genuinely thrilled that he now gets to spend eternity with you in his realm.

Barbatos

His reaction is calm on the surface, but inside, he’s overwhelmed with gratitude.

He saw countless timelines where you never returned—this one is rare and precious.

Swears in his own quiet way to serve and protect you, just like he does with Diavolo.

Always appears when you need him, no matter where or when.

If anyone tries to harm you, they’ll simply… disappear.

Solomon

Absolutely fascinated by your transformation—wants to document everything.

Still calls you “human” just to tease you.

Says this means you can now join him in more dangerous magic experiments without dying so easily.

Lowkey protective in his own chaotic way—summons creatures to watch over you when you’re apart.

Glad that now you have the lifespan to match his.

Simeon

His smile is bittersweet—he’s happy you’re alive, but sad you’ve fallen from grace.

Still treats you exactly the same, angel or not.

Reminds you that your worth isn’t tied to your form—it’s tied to your heart.

Becomes even more protective of you in the Devildom.

His hugs linger a little longer, as if he’s making sure you’re real.

Raphael

Sighs when he sees you, muttering about how you “couldn’t stay out of trouble even in death.”

But there’s a flicker of relief in his eyes that he can’t hide.

Offers to train you in combat—“if you’re going to be a demon, you should be a competent one.”

Keeps his emotions under wraps, but you catch him watching you with a faint smile sometimes.

If anyone insults your change, they’ll mysteriously end up with a black eye.

Mephistopheles

Pretends to be unimpressed, but it’s all an act.

Secretly thrilled that your “new form” is just as charming as before.

Says you should write for the paper about your death and rebirth—“It would sell like crazy.”

Defends you fiercely if anyone calls you a lesser demon.

Insists on teaching you Devildom politics so you can thrive.

Thirteen

The moment she senses your aura, she stops dead in her tracks.

Then she bursts out laughing—“So you came back on my side now?!”

Thrilled to have you as a fellow demon, immediately starts dragging you into her pranks.

Also swears she’ll kill anyone who tries to take you away from her again.
