Chapter Text
Kat was staring at Satan, standing in front of her in his new Arabian-inspired outfit. He looked absolutely amazing, and it was so distracting. She could see Satan's whole chest! And the jewelry draped over him? Hot.
God. She can't deal with this. Where's Gemma when you need her?
"...So?" Satan asked. "What's the deal? Why did all of us get summoned here on such short notice?"
Kat cocked her head at Satan, so they were called without explanation as well? She was just used to being summoned randomly. Usually by Lucifer, but whatever.
"Well, I heard that it's about something important," Asmo replied.
Kat immediately bit her lip to contain her response as she saw Asmo's costume. This might be the sexiest outfit she's ever seen him in. Her eyes traced over his figure as much as she dared.
She blushed a dark red when he noticed and sent her a playful wink. She immediately changed focuses, to embarrassed to keep looking. She turned to Leviathan, smiling at his much cuter outfit.
He had so many gold necklaces on and her coat was just adorable. He was pouting - like usual - and she just wanted to smush his face in her hands and kiss him.
"You know, there's some anime I was hoping to watch, and it's starting soon." He complained.
Beel spoke next. His huge, well-built form was draped in just the right amount of jewelry. Wearing a beautiful coat. And his bright smile was so beautiful. God, Kat was so lucky to know all of these men.
"You think maybe this is about food?" He asked hopefully.
"I doubt it, Beel." Belphie commented. Now Kat was just distracted trying to mentally catalog all the ways his outfit was different than Asmo's. They were quite similar. Belphie was missing one arm, and had a lot more jewelry, and his shirt was cropped quite a bit shorter, showing more of his stomach.
"You guys don't think it could have something to do with this human here?" Mammon asked, and Kat just grinned at Mammon and his costume. She didn't even bother mentally categorizing his nearly bare chest. She's seen his demon form before!
"It better not." Mammon huffed.
But why was he acting like they've never met before? She was surprised he wasn't complaining about her gawking at his brothers-
"Oh!" Kat said out loud, finally figuring it out. Then she turned red when all eyes were on her for her unexplained outburst. Barbatos must have sent her to one of those parallel worlds! Hopefully Gemma shows up soon, she misses her when she's not around.
But for now, she would enjoy this.
"You, human! Say somethin'!" Mammon ran out of patience, waiting for her response.
Kat decided to play along with this game, not questioning their outfits or what was going around. Putting herself back in the mindset in the beginning. "Is this some sort of a dream?" She asked innocently.
Asmo giggled. "Hehe, don't you say just the cutest things?" He asked, sending her that beautiful smile of his.
"You lot. Calm down." Lucifer ordered, his arms crossed. Kat liked his outfit, it was layered quite beautifully. But it wasn't as... interesting as his brother's outfits. In her opinion, at least. It was rather bland, especially when compared directly to Asmo or Beel. "Lest you forget, the seven of us are part of the royal line, so I expect you to carry yourself with dignity at all times."
Oh. That's different. But then, what is Diavolo doing in this world. Is he just gone? Oooh, what outfit is he gonna wear?
"Right. Yeah. Whatever." Mammon shrugged, still looking rather irritated.
"The prophet Diavolo has something to tell you. I'm going to give him the floor now." Lucifer declared. Kat was distracted by the sight of his nails, suddenly realizing that - even in bed - she has never seen Lucifer without his gloves on until now!
"Thank you." Diavolo gave a warm smile. "I come bearing a prophecy. One that I think you'll all find very interesting."
Kat almost pouted. How boring. He was just in his demon form. Come on, Diavolo as a PROPHET? How could you just not do anything aesthetic with that idea!
"Last night, I discerned a message in the stars. And now I will pass it on to you." Diavolo informed. "Whoever marries this human will gain the power to rule the world."
Okay, scratch the Barbatos idea! She was in one of Levi's dating sims! Astounding. This is gonna be, just, so much fun.
Levi gasped in shock, "What...?"
"Did you say.... marries?" Belphie asked, arching an eyebrow.
"Wha....wait wait wait wait!!" Mammon never changed, regardless of the rules of the world he's in. "WHAT'D you say?!" He shouted.
"He said that whoever marries this human-" Satan looked rather shocked, as he stared at Kat.
Kat just grinned back at him.
"-Is gonna gain the power to rule the world?! Seriously?!" Mammon interrupted.
"If you heard him the first time, why ask him to repeat himself?" Asmo rolled his eyes, annoyed at the waste of time.
"When you say "the power to rule the world," what exactly does that entail?" Belphie asked.
Honestly, it was a good question. She'd let Diavolo give an answer that fits this reality before she BS'ed her own answer.
"Like, does it mean all the food in the world would be yours?" Beel asked excitedly.
In an almost robotic motion, Kat reached into her purse and grabbed one of the snacks she keeps on her. She reached over to hand it to him silently.
His bright smile in response was worth the weird looks the other brothers were currently giving her.
"Oh, and all the anime merchandise too...?!" Levi asked excitedly.
Kat gave Levi a wide grin. He's just so cute when he's excited.
"So this human actually possesses power like that..." Lucifer stared her down, trying to decipher the truth.
"You betcha." Kat answered, giving them an easy smirk. After all, she probably did. In this world, at least.
"Okay, not it really sounds like you're lyin'..." Mammon rolled his eyes.
Kat gasped, as if genuinely offended. She put her hand up to her chest in pseudo-offense. "I absolutely cannot believe you would even say such a thing about moi."
Lucifer huffed, "All of you, think about it for a moment. Have any of Diavolo's prophecies ever been wrong?"
"...No." Belphie had a petulant pout on his face.
"Nope, they haven't." Asmo admitted, a rare serious look on his face.
"Exactly." Diavolo sounded proud of himself. "The prophecy is true. This human, Kat, possesses a mysterious sort of power."
"For real? Whoa..." The shocked look on Mammon's face made Kat smirk.
"...Well, that settles it." Lucifer came just... too close to Kat. Giving her those bedroom eyes that made her so conflicted. Cause on the one hand they were kind of dreamy, and on the other hand, she didn't like that... that... domineering attitude that always came along with it. "Kat, you're going to marry me."
This is exactly what she was talking about! It wasn't a question, or a hope, but it also didn't seem to be a demand. A mere statement of purpose. An arrogant declaration that he would marry her regardless of her feelings on the matter.
"...What?" Satan's eyebrows arched immediately.
"Of the seven of us, I'm the eldest." Lucifer declared, not even deigning to respond to his brother's outburst. "I'm the most powerful and the most influential. So I'd say it's only natural that you should marry me, Kat."
Kat almost immediately had to bite her lip to keep from scowling at him. Wow. Is that really what she seems like to him? A power-hungry shrew who just wants to amass influence? It makes her hackles raise. Intellectually, she could see that he's looking at this from the royal perspective. But on the other hand, it still really ticks her off.
"I have no interest in your power or influence." Kat was perhaps being harsher than usual. She immediately winced and hurriedly attempted to correct herself, seeing how rude she was being. She didn't like being that rude. "What I mean to say is... I uh... I think there's plenty of good things about you besides your power."
Which was true enough. Kat's favorite things about Lucifer have always been his genuine attempts to take care of his siblings and his responsibility. She could always depend on him for assistance if she needed it. And personally, those were so much more important to her than his influence.
Kat almost didn't notice the shock on his face, so lost in thought. But she did notice the way a genuine smile brightened his face. He was so handsome when he actually smiled. "I have to say, I didn't expect you to say that."
"That's it. I'm not going to sit here listening to this." Satan scowled, interrupting their "flirting" or whatever they wished to call it. "No one else in the land has read more books than I have, and no one is more knowledgeable. If anyone should rule the world, it's me."
Satan gave her one of those beautiful smiles of his, "I will be the one to marry you, Kat." Despite his words being the same, the tone in which he spoke was so much less presumptuous. Kat was not nearly as irritated by them. It was almost, hopeful.
"So you're an avid reader?" Kat thought that this situation would be good for heaping praise on all her boys, who were all so special to her in their own ways. "Wow, that's great!"
The way Satan's eyes widened before he looked down as his cheeks darkened was just delicious. How absolutely adorable. Oh she could just eat him up!
"Well, it's... my hobby, that's all." He told her, rather embarrassed by the praise.
"All right, you two. Settle down. It isn't up to you to decide." Diavolo tried to reign them in/ "Kat is the one who gets to choose whom to marry and love."
"Obviously, that's going to be me." Lucifer declared.
"Wrong. It's going to be me." Satan scowled at his brother.
"Whoa, hey..." Mammon frowned at them.
"Lucifer and Satan are both being so pushy..." Leviathan pointed out, frowning.
"Yes, but that's nothing new, is it?" Belphie sighed.
"Listen, Kat." Asmo held his hand out for her, "Why don't we get you out of here now while we still have the chance?"
"Come on, this way." Beel led her out of the room.
