Beatrice summons Lucifer, who makes the first offer.

"Now, Ushiromiya Battler..." Beatrice stepped forward, holding her hands up with their backs towards him. "You and I are going to perform some magic. Your own talents are pitifully poorly suited for it, but with my instruction, you shall be a master summoner in no time."

Battler still looked fully confused, but he hid it behind a natural grin as best he could. "Hihi... Magic, huh? You two sure go on and on about that."

"Naturally! Magic is the most powerful **** in this world, Battler. With it, a human can grab hold of whatever sinful desires his heart can imagine. Would you like to satisfy your greed? Your lust? Let us find out which sin governs your nature-"

"Woah!" Battler took another, larger step back, realizing the witch was trying to place her hands over his eyes. "Hey, hey! This is kind of a sketchy scenario for me to let you blind me just like that!"

"But I'm not trying to blind you, Ushiromiya Battler. I am trying to open your eyes to a presence who has been here with us, the entire time... Kihihi!!"

"Yeah, well, forgive me if I don't find that very convincing. Besides, I only trust what I can see with my own two eyes!"

"Ho! How manly." Beatrice smiled, although she looked a bit impatient. "With that pride of yours, the summoning should be relatively simple, even for a simpleton like you. Fine. Close your eyes yourself, if you're going to be a baby about me touching your precious face!"

Battler sighed, then finally shut his eyes, although it was easy to imagine he was squinting through his lids. "What's next?'

"Now... Let us perform the ritual. Let us recall the form of Lucifer, the Eldest of the Sisters of Purgatory, she who governs the sin of pride. I want you to picture my furniture in all of its splendor-"

"Furniture?! I thought we were talking about-"

"Do not interrupt! Simply listen to my words, and give form to her. Repeat after me, if it helps you... Picture Lucifer's pale, youthful body, her unblemished flesh. Picture her dark hair, long, straight, and beautiful, as much of a source of pride as any ability for her. Picture her red eyes and fanged teeth; these mark her as a demon, but do nothing to detract from her ethereal beauty. Picture her provocative dress, guaranteed to ensnare the hearts of men: her short red jacket and tight vest over her white shirt and inappropriately playful pink tie, and a lovely, form-fitting leotard that hugs her hips like a lover... Now, you must picture her cute, round butt, for that is your helpless male nature! It is hidden from you by her short skirt, yet the skirt does nothing to hide her enticing thigh gap from the front. Picture the garters that cross her thighs on the way to her dark stockings, her long and lovely legs tucked into tall, fashionable boots... Lucifer. Long, dark hair. Red eyes, fanged teeth. Red jacket, red vest, white shirt, pink tie. Black leotard, black skirt. Cute butt. Black stockings, brown boots. Picture her, Battler."

Obviously feeling fully ridiculous, Battler nonetheless did what he was told. He seemed to have the same reverence for this ritual as he would if Maria was begging him to play along with a magic trick. Beatrice made him repeat the description over and over...

... And, as she did, I saw Lucifer's form gradually come into view. Her face was already fully flushed with indignation, and I saw her eyes screw up in a wince every time Beatrice and Battler repeated "cute butt" as one of her necessary summoning characteristics. Finally, when she was almost fully solidified, she let out a yell. "Lucifer of Pride, right heeere!!"

Battler's eyes shot open. Then, he rubbed them thoroughly with his fists. It didn't seem to do any good. "What... the hell... This is her, isn't it? This is... that Lucifer with the cute butt we were-"

"Yes, the Eldest Sister of Purgatory, Lucifer of Pride!" Lucifer interrupted him, brandishing her sword reflexively. "Lady Beatrice, why have you allowed this buffoon, completely bereft of talent, to summon me...?!"

"Hmhmhm... Kyahahaha!!" Beatrice threw her head back and cackled. "Amazing! Truly improbable! To think, Battler was capable of summoning my high-specification furniture! Lucifer, you are going to help me to **** Battler to submit to my power!"

"Oh... Of course! It will be my pleasure-"

"You will help me **** him to submit with that cute butt of yours!"

"Oh!" Lucifer gasped as Beatrice knelt alongside her.

Effortlessly, the witch spun her furniture around and used one hand to raise Lucifer's skirt, pressing her own cheek to the side of the demon's hip while using her other hand to frame the leotard-clad ass. As she did so, she showed Battler a taunting grin, gazing into his eyes and trying to make sure they locked where she wanted. "Seeee? Incredible, high-specification furniture is mine to command! And, for tonight, my command is for her to dance for your pleasure, Ushiromiya Battler! All you must do is grant her one of these favors."

Lucifer glanced around as though looking for somewhere to escape to, then showed Beatrice her unenthusiastic face. "Lady Beatrice... I am happy to do as you command, but... You needn't have him offer me something as insignificant as human money...!"

"Ho! You are proud, after all." Beatrice gave Lucifer a teasing squeeze, showing even more teeth as the young woman squirmed. "However, I said these are Witch's Favors, did I not? For my furniture, money is of little consequence, but a favor can be much greater! Let us set the terms, Lucifer. If Battler grants you the first of my favors, I will grant you... Hm! A high quality kill. I will guarantee you that the next time I unleash you for my ritual, your prey will be only the finest, such that your renown will grow among your sisters!"

Immediately, Lucifer's eyes sharpened and her bearing changed entirely. Beatrice seemed to know exactly what to offer her furniture to get results out of them. "Battler! You are afforded an opportunity humans can only dream of! If you grant me this favor, know that I will do all I can to please you with... my body, which you summoned with your pride..." Even though she wanted to act tough, Lucifer glared at the floor stubbornly as color stayed on her face.

"I wonder if his pride is what summoned you?" Beatrice teased again, bouncing Lucifer's buttcheek playfully once more and making her gasp. "It was some other sin, wasn't it? Wasn't it, Battler?!"

A witch and her furniture had appeared before him... Battler must have been stunned. Still, he was a hot-blooded young man. Surely he wouldn't let this opportunity pass him by, a night of literal fantasy? Lucifer doesn't offer this sort of thing to a human every day, Battler!
