Lucian glanced across the dinner table at Serafall Sitri — or rather, at the self-proclaimed Levi-tan, the Magical Girl of Love and Justice! — who was, for once, uncharacteristically composed. Her usual sparkle was dimmed, replaced by the calm demeanor of a stateswoman. He found it oddly amusing.
So she really can turn off the glitter when needed, he mused.
Still, a part of him couldn't help but imagine her reaction if he ever showed her an actual world of magical girls. He could do it — in theory. His Essence of Nomad could anchor him anywhere, even across dimensions. The problem was where exactly he'd land. The Essence prioritized familiarity and anchors, meaning unless he'd seen or known the world, it was a roll of cosmic dice.
Would he appear in a parody world filled with sparkles and transformation sequences… or a grimdark one where "magical girls" hunted eldritch gods? Either way, it'd be a trip.
For now, though, the dinner itself was... boring. Painfully so. Even Serafall's parents, Lord and Lady Sitri, spoke in the polished tones of political hosts, and Sona — ever the model daughter — matched their formality with practiced precision.
Lucian, seated quietly beside her, smiled politely through the small talk. He had no idea that beneath this quiet surface, a domestic storm was brewing.
Because while Lucian thought this was just another formal dinner, Sona had, in her usual logical-yet-stubborn way, just informed her parents that she wanted to marry him.
And the reason was simple — the Affection System had already done its work.
{Sona Sitri's Relationship Progressed.}
{Current Score: 99.}
{Relationship Type: Deep Crush → Lover.}
{Affection Threshold: Romantic Feelings → Love.}
Her parents, naturally, were confused. Their daughter, ever cautious and analytical, suddenly declaring love for a man she'd known barely a month? That was a first, even for the Sitris.
Thankfully, Serafall's intervention (and Lucian's undeniable charm and strength) smoothed things over — though "smoothed" might have been generous. The atmosphere that evening hovered somewhere between awkward and politely pretending everything was fine.
To Lucian, though, it all just felt like another stiff political dinner. In his last life, he'd attended similar events representing his country at chess tournaments — the same polite silences, the same half-hearted laughter.
So, after exchanging obligatory pleasantries, he excused himself to the guest room.

Lucian fell asleep quickly, drifting into a landscape of fractured color and soft static — Amanush's domain.
Amanush, the Dream Watcher, lingered there — its form shifting like liquid glass, a thousand unblinking eyes studying him. Though it couldn't speak, its thoughts rippled through the dream.
Lucian crossed his arms, smirking faintly. "Still trying to impress me with these half-baked illusions?"
The creature's essence pulsed in mild embarrassment.
He sighed. "You know what? Let's make you useful."
A faint shimmer rippled across the dreamscape as he gave the order. "Go to Riser Phenex's dreams. Give him nightmares — creative ones. Especially about that arranged marriage with Rias Gremory. When you're done, pay Diodora Astaroth a visit. Make it unpleasant."
Amanush's eyes flared in acknowledgment, and it vanished into the dream currents.
Lucian's grin darkened slightly. "That should keep him busy."
In another region, Riser's dream fractured into chaos.
He stood at his own wedding altar, only for Rias to turn away — not to another man, but to his own Queen, Yubelluna. The noble devil froze in horror as his elegant suit melted into a pink tuxedo with hearts, and a priest declared him "the most faithful spectator." His wings refused to move, locked in place by invisible chains. From the pews, the Phenex clan applauded with polite horror.
In the real world, Riser shot awake screaming, clutching his chest.
But this was just the start of unpleasant dreams for him — all of which began with his marriage to Rias and ended with him in extremely… painful situations.

Lucian, now free from Amanush's attempts to impress him, once again tried to sleep.
But before he could drift deeper, his Universal Perception flared — a whisper of killing intent in the dark.
His eyes opened instantly. Someone was in the room.
The pressure was faint but deliberate — a trained assassin. Not a Devil, either. The energy signature was off, denser, colder. A Demon.
What's a Demon doing in the Underworld?
The moment the intruder moved, Lucian's leg shot out. His heel connected, sending the demon crashing into the wall with a metallic crack. The plaster exploded, dust filling the room.
"Lucian-chan!"
Serafall appeared in an instant, her aura washing over the room in a surge of blue light. With a flick of her wrist, a crystalline water barrier sealed the demon in a sphere of liquid stasis.
"Who's this?" she asked, her tone still cheerful but with a razor edge beneath it.
Lucian dusted his sleeve. "Probably an assassin. No clue who sent him. I don't remember offending anyone lately."
"Hmm… maybe someone targeting my family," Serafall murmured, tapping her lip thoughtfully. "But I couldn't even sense him until he attacked. That's… impressive."
"Thankfully, not impressive enough."
Lucian's eyes glowed faintly silver as his All Seeing Seer activated. The world slowed, every detail unraveling — the demon's fragmented soul-memories spilling open like pages in a book.
No name.
A lineage — Blanc.
A unique skill — Unperceived, perfect concealment even from divine senses.
And the client — a low-class Devil, anonymous, paid in human souls.
Lucian closed his eyes, filing away the data. "He's from Blanc's lineage. Professional hitman. The Devil who hired him's probably a scapegoat. There's definitely someone higher."
Serafall blinked. "You… got all that in a few seconds?"
He shrugged. "Perks of good eyesight."
She stared at him for a beat, then laughed softly. "You're dangerous, you know that?"
"Only when people interrupt my sleep."

A flash of teleportation later, they appeared in a dark alleyway. The stench of blood hit first — and then the sight.
A headless body slumped against the wall, the severed head lying neatly beside it, expression frozen mid-terror.
Lucian sighed. "Well, that lead's gone."
"Not necessarily," Serafall replied, eyes narrowing with a calculating gleam that didn't suit her sparkly persona. "If this Devil really was the intermediary, I can handle it from here. I might be Levi-tan, but on the side, I am the foreign minister of the Underworld, after all."
Lucian arched an eyebrow. "And here I thought you were full-time Maou."
She puffed up proudly, placing a hand on her hip. "Nope! I'm full-time Levi-tan and part-time Maou. Multitasking!"
Lucian couldn't help but laugh. "Alright, Levi-tan. I'll leave it in your hands."
Serafall gave a mock salute, her smile dazzling. "Consider it handled!"
---
Back at the Sitri mansion, Lucian explained the situation to the family — who, to his surprise, handled it with composed pragmatism. Lord Sitri simply nodded and ordered stronger wards placed. Lady Sitri looked more concerned that her daughter's new boyfriend had nearly been assassinated than anything else.
When the house quieted again, Lucian was moved to a new guest room. For once, he managed a few hours of dreamless sleep.
He remained with the Sitris for three days afterward. With Serafall off managing the investigation, the house was calmer — though Sona's parents took the opportunity to speak to Lucian properly.
They asked about his past, his abilities, his intentions — the kind of questions any protective parents would ask.
Lucian answered honestly — or at least as honestly as one could when dealing with multiversal nonsense.
Lord Sitri finally smiled faintly. "You're… quite composed for someone so young."
Lucian chuckled. "Experience ages you fast."
Lady Sitri nodded approvingly. "Sona has good taste."
That earned a rare blush from Sona, who promptly changed the subject by bringing tea.
---
By the fourth morning, they were ready to return to Earth.
As they stood near the teleportation circle, Sona adjusted her glasses, glancing at him with quiet fondness. "You really didn't have to stay this long, you know."
"I didn't mind," Lucian replied. "Besides, your parents make excellent tea. And your sister makes an excellent magical girl."
Sona groaned softly. "Please don't tease my sister like that."
"I'd never," he said with mock sincerity.
Her lips curved despite herself. "You absolutely would."
He smiled, leaning closer. "Maybe."
The teleportation array lit up, washing them both in white light. As the world shifted, Sona's hand brushed against his — a simple, wordless touch that grounded the chaos of the past few days.
When they arrived back on Earth, night had already fallen. Kuoh's skyline shimmered under faint moonlight, quiet and still.
Lucian looked out toward the horizon, feeling the weight of countless possibilities tug at his mind — the threads of different worlds, fates, and stories crossing in the dark.
Sona turned to him, her tone soft. "So… what now?"
He smiled faintly. "Now? We live together. Maybe I'll get that promised night."
She rolled her eyes. "You're insufferable."
"Yeah," he said quietly, "but you love that about me."
Sona didn't deny it.
A/n: Writing Serafall is hard... On one hand I'm thinking of going full on Levi-tan on other hand I want her to actually be competent too.. Hopefully writing Milim wouldn't be hard...
Should I go for some Serafall Yuri route?
