Mayaa

Dio

“What is this… rodent.” Absolute disdain.

Momonga immediately clocks him as someone with authority and decides ‘this is my target.’ Screams directly in his ear while hovering.

Dio tries to command them. “Be silent.” Momonga: SCREEEEEE louder.

You cuddle Momonga in a blanket and they calm down instantly. Dio watches this happen and his brain short-circuits.

He starts calling Momonga “your familiar” like you’re a witch.

He pretends not to care but absolutely threatens anyone who even looks at Momonga wrong because it’s yours.

“It is... utterly insufferable...”

Kars

Immediately understands that Momonga is not normal.

Fascinated. Obsessed. Tries to figure out what species they are and why their vibes are rancid.

Momonga hates him because he doesn’t react emotionally enough.

Screams at him. Throws fits. Kars just stares like: pathetic.

He figures out Momonga wants attention and starts calmly holding them while they yell themselves tired.

Momonga bites him. Kars doesn’t react. Momonga is offended.

Eventually Momonga naps on his shoulder because his body heat is perfect.

Kars absolutely would modify himself to have wings just to flex back at them.

“They are loud, rude, and inefficient.”

Yoshikage Kira

HATES the noise. Immediately.

The screaming? The sudden movement? The unpredictability?? Nightmare fuel.

Momonga LOVES terrorizing him. Screams specifically when Kira is trying to relax.

Momonga knocks things over on purpose. Kira is dying inside.

You’re like “they just want attention” and he’s like -_- no animal should want THIS MUCH.

Secretly very gentle with them though.

Wraps Momonga in a blanket burrito to stop the chaos.

Momonga stops screaming instantly and cuddles him. Betrayal.

Kira never speaks of this again. If anyone brings it up he denies it violently.

Diavolo

Does not trust Momonga. At all.

Sees them screaming and immediately assumes it’s a threat.

Momonga senses fear and power. Targets him relentlessly.

Flies at his face. Screams. Pulls his hair.

Diavolo has used King Crimson to skip Momonga tantrums. Canon.

When Momonga calms down and curls up with you, Diavolo relaxes.

Ever so slightly jealous that you give Momonga more affection than him.

Would never hurt them, but keeps them at arm’s length like they’re a bomb.

“That creature is a liability.”

Doppio

Immediately wary of them. Tries to keep it happy so it’ll leave him be.

Thinks their screaming is just “them talking”.

“Oh! They’re upset… Um maybe they want a snack?”

Momonga screams. Doppio nods like yeah that makes sense.

Wraps Momonga in a blanket and rocks them gently.

Momonga quiets down almost instantly because Doppio gives pure, unfiltered attention.

They ride on his head.

Doppio would share his snacks with them and apologize if they yell.

Momonga would absolutely choose Doppio as their favorite human.

Enrico Pucci

Tries to rationalize Momonga’s behavior.

“They are simply expressing desire.”

Momonga screams during prayer. Repeatedly.

Pucci closes his eyes and breathes through it.

Wraps Momonga up carefully and speaks softly to them.

Momonga is still rude but slightly less feral with him.

He believes Momonga was placed in your life for a reason.

Sees them as a test of patience and devotion.

Smiles softly when Momonga finally falls asleep on your chest.

Funny Valentine

Calls Momonga “a menace to society.”

Still spoils them.

Tries to bribe Momonga with treats to stop screaming.

It works. For five minutes.

Momonga screams louder when the treats stop.

Valentine sighs and gives them more.

Holds Momonga like a grumpy dad holding a screaming toddler.

“This creature represents the chaotic freedom of this nation.”

Would 100% get Momonga tiny patriotic accessories.

Diego Brando

Immediately beefs with Momonga.

“Why does it keep yelling.”

Momonga yells back at him. Direct confrontation.

They scream at each other. You have to break it up.

Diego absolutely refuses to admit Momonga is cute.

Gets jealous when Momonga clings to you.

But the second Momonga curls up on his jacket? He’s done.

Pretends it’s temporary. Lets them stay.

Would fight someone if they called Momonga ugly.

Tooru

Knows immediately Momonga is dangerous.

Not physically, emotionally.

Momonga screams and demands attention. Tooru ignores them.

This drives Momonga insane.

They escalate. Louder screams. More chaos.

Tooru calmly gives them affection once.

Momonga is now obsessed with him.

They sit on his shoulder like they own him.

Tooru pretends not to care but absolutely lets it happen.
