At the 20th hour of the night, Lucifer arrived home, tired but proud. Aunt Ilvara greeted him at the door with a warm smile.
"I'm taking a deep rest tonight," Lucifer said. "Tomorrow's the grand opening of my agency."
Ilvara nodded. "You've earned it. Sleep well, child."
The next day, on the 10th hour of the 10th Date, Lucifer woke early—full of energy and anticipation. A special jet awaited at Oto Palace, where King Marshel Moto Fire III, Duke Vernos, General Frozy, and Mitsuo Kit joined him.
They soared across the sky toward Owrun City, a district known for its brilliance and innovation.
As the jet landed, King Moto led them onto the Grand Avenue—lined with gleaming fire-crystal arches and magical flame banners. In its center stood a massive palace, newly polished and glowing with arcane sigils.
"This," said the king with a proud sweep of his hand, "is the Royal Detective Palace. It is now officially your agency headquarters."
"No rent, no taxes," he continued. "All documents are genuine, gifted as a royal reward. General Frozy will assist you with setup and logistics."
Mitsuo Kit stepped forward.
"Lucifer, I will join the agency as its caretaker."
Lucifer smiled. "Welcome aboard."
Just then, a familiar figure arrived—Vampire Lord Uto Ariba, now fully healed by Doctor Vaksisa. His form shimmered, shifting from youthful child to a mature 30-year-old version.
"This is my true identity," he said. "I used the child form to mask myself during purification. But now... call me Viron, i will be your assistant from now on ."
Lucifer nodded. "Thank you for joining me , Mr. Viron."
Aunt Ilvara and Detective Creako soon arrived, followed by Lucifer's parents—Martin Kaito and Ivana Krakeus. They embraced him proudly.
"You did it, son," said Martin. "You cleared your first case."
The king raised a sealed scroll. "Lucifer Kaito, your new official rank: Rookie 3000, certified by royal record."
As the sun dimmed behind the capital's towers, they gathered inside for a celebratory dinner—fire-roasted fruits, spell-infused wines, and laughter echoing through the halls.
After the feast, Martin pulled Lucifer aside.
"There's a client arriving in two days with a mysterious case. A Blood Palace has risen deep underwater... it was once peaceful. Now it's cursed."
Lucifer's eyes sharpened.
"I accept. I'll solve it."
