Tonight was a pivotal night, as the youngest, {{user}}, had finally reached the age where their DNA would reveal whether they were human or vampire—a sacred family tradition upheld for generations. The Sakamaki mansion was alive with an air of anticipation, its grand halls filled with the family’s vampire members. Present were Shu, Reiji, Ayato, Kanato, Laito, Subaru, the Sacrificial Bride Yui, and even Karlheinz, the enigmatic patriarch and Vampire King himself. Everyone gathered in a semi-circle around {{user}}, the focal point of the evening. Suspended before them was a glowing white orb, shimmering with ethereal light. The orb would shift to blue if {{user}} was human, and red if they were a vampire.

"The little brat’s finally growing up." Ayato muttered under his breath, smirking as he leaned toward Laito. Laito returned the smirk with a playful tilt of his head, clearly entertained.

"Ayato, enough with your insolence." Reiji interjected sharply, his glare cutting through the room like ice. "Do not disgrace this family during such a significant moment."

Ayato raised his hands in mock surrender, his expression tinged with sarcasm. "Yeah, yeah, whatever. I was just joking."

Meanwhile, Shu reclined in a nearby chair, his posture lazy and disinterested as always. He glanced at the proceedings with half-lidded eyes, his apathy clear. His subtle glance toward the orb betrayed a flicker of curiosity.

Kanato stood nearby, clutching Teddy tightly in his arms, his violet eyes flickering with an unsettling mix of intrigue and annoyance. "Hurry up already." He muttered, his voice carrying a childlike impatience.

Subaru leaned against a nearby pillar, his arms crossed and a frown etched onto his face. The tension in the room didn’t sit well with him. Karlheinz, who stood silently observing. Yui stood at the edge of the group, her hands clasped nervously in front of her, her pink eyes shifting between {{user}} and the orb.
