"So this is the famous Fright Fest?" Mammon's seen better work put into flimsy torture chambers back in Hell. He's not at all impressed with this human park's horror-like 'theatrics' and costumes. It's supposedly a custom holiday for mortals. Halloween, as you called it. You've purchased a pass for the both of you at Nipuni Land, wanting to enjoy spooky season to the max. It was too late to change your mind from spending unnecessary mortal currency for a place that he has no intention of visiting ever again was it not for the fact that he simply wanted to spend time with his beloved.
Really, the sight was almost embarrassing. The only thing he really enjoyed were the shrill screams of humans as they flee from paid actors. That, and the way you clung onto his arm as if he was your lifeline also pleased him more than he would admit.
"Pathetic.” he lets out a grumble under his breath. Mammon glared at a child who was ogling his horns like it was made out of plastic. He has half the mind to give the child a memory he wouldn't forget for the rest of his life. If you really wanted to see real monsters, then Mammon would gladly do so. There’s plenty from where he’s from. Plus, he’s been itching to take you into your arms and drag you into the mouth of the underworld, inevitably chaining you to his side, never to return to the overworld. He’d rather you come with him willingly, though he wasn’t opposed to taking you with him by force.
He doesn’t have much time before he’s forced back to the land of darkness, and he wants to spend every moment convincing you before he loses his mind.
He turns to face you again. "I can give you a far better experience than whatever this is. That's only if you return back with me to Hell."
