Familiarity

"This is your bedroom? Isn't it a bit small for someone of your status and import?" asked Serafall, looking around Vahn's repurposed club room with a curious gleam in her eyes.

"Rias and Sona offered me a villa of my own, but I don't really like excess and extravagance..." explained Vahn, removing his ribbon and unbuttoning his dress shirt.

"That's more common than you might think," responded Serafall, turning to face Vahn with a playful smile as she explained, "But there is a meaning behind such extravagance. Because of the nature of Magic, the resilience and efficacy of barriers and seals are greatly influenced by the perception of large groups of people. If the average person were to see a shack, they would assume its defenses are weak and that it can be toppled easily. On the opposite end of the spectrum, a fortress the size of a mountain gives the impression of impregnability, strengthening its foundation and making the barriers protecting it more resilient."

"Makes sense," assented Vahn, nodding. He had learned the importance of symbology and the power of belief from his magical studies with Rias, Sona, Akeno, and Grayfia. However, as it would be rude to tell Serafall he already knew what she was trying to teach, he accepted her lesson with a smile and proposed, "Do you want to relocate to the Corridor? We have a hot springs villa and a castle we use for recreation."

"Are you sure you're not asking that to extend your sixty-five minutes to multiple hours~?" asked Serafall, angling her head downward to stare at Vahn with upturned eyes as she tentatively pulled at the green cord that kept her obi in place.

"I wouldn't mind if that ended up being the case..." responded Vahn, his tone calm as his expression eased into a smoldering look.

"Then let's make things official~" hummed Serafall, raising and spreading her hands as a large hourglass appeared from a burst of pink smoke with illusory stars and sparkles.

"The sands in this hourglass will stream for precisely sixty-five minutes," explained Serafall, flipping the hourglass upside down and releasing it to float in the air as she added, "You have until it's empty to impress me with your capabilities and manliness."

"Alright," responded Vahn, nodding and approaching Serafall without fear, grasping her waist as he casually affirmed, "I'll be sure to give it my all..." before transferring them to the Checkpoint housing the hot springs and Ryokan. Serafall immediately released a faint pulse of Demonic Energy the moment they arrived, but her blue eyes were focused on him as he slid his hands to her bottom and raised her to the tips of her toes.

Seeing Vahn's hair shift to black with a slight purple hue and his eyes turn a luminous shade of violet, Serafall narrowed her own, the smile on her face becoming more prominent as she inquired, "Are you going to call me Onee-chan next~?"

"Sera..." responded Vahn, his voice deeper than usual as he turned his head slightly and slowly drew his face closer to Serafall's. There was a glimmer of disappointment in her eyes as she observed him, but instead of insisting that he call her Onee-chan or something similar, she ultimately closed her eyes, raised her chin, and puckered her lips to allow him to kiss her.

Sensing that Serafall wasn't really into them making out despite readily engaging his tongue, Vahn pulled away after a few seconds, causing her brows to rise as he proposed, "Since we've got time, want to look around and destroy some things...?"

"It depends," responded Serafall, her expression and tone playful as she asked, "Did So-tan coach you to make such a proposition?"

Shaking his head, Vahn revealed, "We've talked about you a lot, but the only thing she's told me expressly is that when we meet, I shouldn't hold back and just be honest. And what I honestly want to see right now is see a real-life Magical Girl in action..."

With Vahn releasing his hold on her and backing away, Serafall stared at him for several seconds before covering her mouth with her right hand to reveal a charm shaped like a magical girl's wand as she responded, "Well, alright then~" in a cutsey, sing-song tone. Then, striking a double-peace pose that framed the top and bottom of her face, she exclaimed, "Sparkle Shine, your command is mine~!"

Though she was capable of transforming instantaneously, Serafall used her Demonic Powers to create a unique space filled with warm pink and yellow lights and sparkling stars of various shapes and sizes. Vahn found himself unable to move due to the space's effects, but he did his best not to let it bother him as he watched Sona's kimono dissolve away in a flash of pink light, revealing her naked but light-obscured form. What followed was her performing a series of graceful and implicitly sensual poses and pirouettes as a pale pink crop top, a frilly pink skirt, dark purple and pink thigh-highs, dark purple heels, dark purple arm warmers that flowed into fingerless gloves, and nurse-like cap materialized on her body. The style and color of her hair and eyes had also changed to dark purple twin tails, and, in place of her previous aqua blues, she now had glowing pink irises that matched her ensemble.

Finishing things off with a flourish of her staff, a 120cm long pink rod with a star-shaped ornament flanked by Devil wings on the end that ended up sandwiched suggestively between her thighs as she made a peace sign over her winking left eye, Serafall exclaimed, "Magical Girl Milky Levi-tan, ready to crush Heaven and sinners alike~!" in a cutesy, high-pitched tone.

Not sure how else to respond, Vahn raised his hands to his chest, gave two thumbs up, nodded, and offered a direct "Very nice..." with a stone-faced expression. Serfall's nearly minute-long transformation and Magical Girl form were a sight to behold, but witnessing something generally only seen in anime in person felt...weird...

"Does Vahn-sama not like Magical Girls...?" asked Serafall, spinning her staff between the fingers of her right hand as she approached him with a relaxed expression.

"It's not that I don't like them," responded Vahn, shaking his head as he revealed, "I don't have much experience with them. One of the very first anime I watched was a Magical Girl anime called Cardcaptor Sakura, but while I found the main character cute, it wasn't as exciting as the Shonen anime I got into later."

"Do you mean Clowcaptor Sakuya...?" asked Serafall, tilting her head slightly as she questioned, "Or is that what it was called in your original world?"

"Here, take a look," said Vahn, purchasing and pulling out the first volume of Cardcaptor Sakura for Serafall to peruse directly. She was exceedingly knowledgeable regarding all things Magical Girl, so it didn't take her long to confirm, "This is almost identical to the Clowcaptor Sakuya I'm familiar with, but the names of the characters and the overall art style are slightly different."

"Yeah, this world's One Pisu, Drag-so Ball, Black, and Menma have nearly the same plots as my world's One Piece, Dragon Ball, Bleach, and Naruto," affirmed Vahn, pulling out volume one copies of each.

"It sounds like our worlds are direct parallels of one another," remarked Serafall, ostensibly flipping through each of the volumes without care but grasping the contents of each page in detail. She could even react to and dodge lightspeed attacks, so if she honed her senses to their limits, each successive page flip would take approximately sixteen years to complete.

"It may seem that way, but from what I understand, there is no direct link between our two worlds..." stated Vahn, causing Serafall to stare at him in intrigue as he explained, "It's more like this world was created after mine, similar to an echo..."

"Does that mean your world—your universe was destroyed...?" asked Serafall.

Shaking his head, Vahn, aided by Sis, clarified, "It still exists, but its past, present, and future have all been written. If you could observe it from the outside and see into it, you could theoretically peer into any point in time and space, but it's no longer possible to influence things without breaking everything."

"Then, if our world is an echo of yours, does that mean you can use your power to create texts and records of events that have yet to come to pass in ours~?" asked Serafall, her pink eyes sparkling as she grew increasingly interested in Vahn, his past, and his abilities."

"It's possible..." confirmed Vahn, having once looked up Highschool DxD in his Shop, finding a functionally infinite list of volumes. However, as he had specifically chosen a Record he wasn't familiar with to avoid knowing what the future held and stressing over it, his expression hardened as he warned, "But bad things happen when you start basing your decisions on things that might happen rather than simply living life to the fullest..."

"Humu, humu...fair enough..." responded Serafall, crossing her arms and nodding several times with closed eyes. Then, meeting Vahn's gaze, she smiled, pumped her fists, and exclaimed, "But now that I know you can reproduce anime from your world that are virtually identical to ours, there are a ton of shows I want to view ahead and see future seasons of! Let's have a watch party...!"

"Alright," responded Vahn, nodding affirmingly before adopting a playful smile and adding, "But since we came here to do naughty things, I think I'll have you sit on my lap and maybe play with your breasts as we watch. Sound good...?"

"Heck, if that's the case, why don't we just throw on some hentai and reenact what we see on the screen~?" asked Serafall, narrowing her pink eyes mischievously as she held her staff in a way that caused the pole to nestle between her thighs, deform her skirt, and press against her most sensitive region.

"Sounds like fun..." responded Vahn, grinning wolfishly and surprising Serafall by picking her up in a princess carry and carrying her into the Ryokan. He trusted Sona's advice, so even though it had only been a few minutes since his and Serafall's first meeting, he did his best to treat her like they had been in a relationship for years. Fortunately, she seemed to find his behavior novel, an amused smile blossoming across her face as she allowed him to do as he pleased...

"Wow, nearly sixty-five minutes on the dot..." noted Serafall, grabbing the hourglass she had left suspended in Vahn's room as the final few grains of sand trickled from the top half to the bottom.

"It's a shame I didn't earn a hundred points..." remarked Vahn, grabbing Serfall's waist from behind and kissing the back of her head. In the end, they had spent nearly the entirety of their seven and a half hours simply binge-watching anime as she sat atop and reclined against him, but with thousands of years ahead of them, he didn't feel they needed to have sex during their very first meeting. He did, however, enjoy fondling her breasts and gently kneading her nipples as she propped her feet on his knees and fingered herself through her pure white, pink-ribboned panties.

Amused by Vahn's words, Serafall exhaled a light-hearted chuckle before sliding his hands to her belly and playfully remarking, "But you did keep to the time limit I set. I'd say that's worth some extra credit...how about five billion points...?"

With Sis dutifully informing him that five billion points, when converted to an equal number of minutes, was approximately 9,500 years, Vahn leaned his head around Serafall's face, causing her to turn and meet him to share a chaste but protracted kiss. They still didn't end up having sex, but when Serafall learned he had a wardrobe full of cosplay outfits to accommodate Koneko's and Asia's penchant for dress-up, she enthusiastically tried on a few before capping things off by giving him one of the most intense, essence-draining blowjobs of his life...
