Summary
Emma Andrich is a twenty-two-year-old university student living an ordinary life—until she suddenly wakes up in December 1888. Time travel would’ve been bad enough, but she quickly realizes she’s no longer in her own world. Instead, she’s face-to-face with Earl Ciel Phantomhive and his unnervingly perfect demon butler.
Desperate to find a way home, Emma clings to the only safety she can find in this dangerous new reality. But when Sebastian reveals she’s his mate, the lines between safety and temptation begin to blur.
Caught between two worlds, Emma must navigate Victorian society, demonic politics, and her own growing attachment to a creature who isn't capable of love. As the days pass, one forbidden question refuses to leave her mind:
Does she even want to go back?*Disclaimer:* English isn't my first language.

Summary
Immortality has a way of draining the color from existence, Astre Phantomhive—who once answered to "Ciel"—learned over the centuries. Desperate to break free from the suffocating monotony of eternal life, he did the unthinkable: he sought out his older twin brother's scattered soul and forged him a new body. Against all odds, Ciel Phantomhive lived again.
They were twins once. Identical in every way. But death has changed everything—Astre is no longer the boy who lost his brother all those years ago, and Ciel awakens to a world he doesn't recognize, brought back by a twin who has lived lifetimes without him.
Astre tells himself he did it to fill the emptiness, to have his brother back after centuries of loneliness. But his carefully laid plans spiral into chaos when murder, dark supernatural forces, and... something unexpected emerge between them.
Something that shifts and changes as they navigate this strange second chance. Something that might become more than either of them anticipated.
It's complicated. It's unexpected. It's exactly what Astre's immortal life has been missing.
And he's going with it.Based on and Inspired by Devils like to Dance

Summary
“We’re investigating a case,” the man in black says slowly. “Deaths related to head and neck injuries, which are particularly common in this prefecture. We were sent to handle it.”
“Are you from the police?” Yoshiki asks.
Or private detectives, but there aren’t any such firms in the surrounding villages. Yoshiki isn’t sure there’s anyone in town who would hire these people and send them here.
“No, no,” the man shakes his head with a smile. “Allow me to introduce ourselves. This is the Watchdog of Her Majesty the Queen of Great Britain,” a soft wave of a white velour-gloved hand toward the one-eyed young man, “and his humble servant,” the hand resting on its owner’s chest. “We have nothing to do with the police and we really hope you’ll agree to help us.”
A one-eyed boy and a man in funeral black appear in Kibogayama, and everything goes to hell.

Summary
“Permission to speak, my lord.”
Ciel looked down, drinking in the sight of his butler kneeling under the desk, a red collar tightly clasped around his neck which was connected to a leash. Sebastian’s shirt and jacket had been discarded in the bedroom well before they arrived at the office.
“You may,” Ciel said lazily as he hoisted a foot onto Sebastian’s shoulder, digging his heel downward.

The line between servant and predator blurs, as a twelve-year-old boy and his demon butler struggle to survive each other, and London, long enough to finish their contract.

The boy mutters something under his breath. Instantly, Sebastian’s head snaps back towards the bed, past what any human neck could manage. The room freezes.

When she finds out that at least one of her brothers is alive, Asteria moves back into her home and joins her brother in all he does, afraid to lose him again.

Summary
“What was that, sweetheart?” Sebastian's voice is distinctly smug.
“Nothing,” He grumbles sullenly.
“I thought I heard a sound… What are you doing now, darling boy? Still reading?”
“No,” Ciel says, short and jerky. His thighs tense around the rabbit, and his hips rock once, delicately, into the plush. He inhales sharply.
Sebastian snickers. “Yes, it certainly doesn’t sound like it.”

Summary
Ი︵𐑼 ۶ৎ - While investigating a criminal among the guests, Earl Ciel Phantomhive notices Onigi. Soft white hair frames pretty doe eyes and blushed porcelain cheeks. Such sweetness is a distraction and Ciel has quite the sweet tooth.
In a room full of masks and schemes, Onigi's unguarded smile is both disarming and dangerous, for even the sharpest Earl can find himself tempted by something pure, if only for a moment.
