Delico-s Nursery May 2026

New viewers should know that Delico’s Nursery is part of a larger franchise. It is actually a prequel to the original stage play TRUMP (2009). The immortal vampire "Trumpe" looms large over the lore. You do not need to know the play to enjoy the anime, but knowing the backstory adds weight. The events of Delico’s Nursery directly sow the seeds for the tragedy that unfolds centuries later in the stage play. The "Nursery" is not just a daycare; it is the calm before a thousand-year storm.

The nursery is populated by a cast of adorable yet powerful vampire toddlers. They are the source of the show's comedy, often using their supernatural abilities to create havoc for the teachers.

The great chandelier of the Vlad Agency headquarters had been dimmed to a soft, milky glow. In the nursery—once a stark briefing room, now adorned with mobiles of carved wooden bats and curtains stenciled with crescent moons—the most dangerous men in the Holy Empire were losing a war.

Not against the shadowy TRUMP cult. Not against the undead aristocrats plotting in the catacombs.

Against bedtime.

“No,” said Dali Delico, his silver hair escaping its usual perfect coiffure. He held his youngest, Umu, against his shoulder, patting her back with the mechanical precision of a man defusing a bomb. “We do not negotiate with toddlers. The schedule says sleep at eight. It is eight-oh-three.”

From across the room, Henrik Klinger, the agency’s bulletproof strongman, sat cross-legged on a rug patterned with stars. His massive hands—hands that had crushed vampire skulls—were now carefully stacking wooden blocks into a wobbly tower. His son, Friedrich, watched with the intense scrutiny of a general reviewing battle plans.

“It falls,” Friedrich announced.

The tower collapsed. Henrik sighed, a sound like a distant avalanche. “Again.”

At the window, Juraski von Hartmann stood guard against the night—or rather, against his own daughter, Angelica, who had decided that the curtains were a magical portal and was attempting to crawl through them. He gently pulled her back by the sash of her nightgown. She giggled, a sound like silver bells, and immediately tried again.

“She has your persistence,” observed Dali.

“She has your insolence,” Juraski replied without turning.

Only Dali’s eldest, Raphael—a boy of seven with his father’s sharp eyes and none of his patience—was quiet. He sat in the corner, not sleeping, but watching. A leather-bound journal lay open on his knee. Inside, he had sketched not childish doodles, but symbols. The same symbols that had been found at the last TRUMP crime scene.

Dali noticed. He always noticed.

“Raphael. Bed.”

“The cipher isn’t complete, Father. If you would just let me see the case files—”

“The only case you have tonight is the case of the missing pillow.” Dali pointed. “Solve it. In your dreams.”

Raphael’s jaw tightened. For a moment, he looked like a tiny, furious version of his father. Then he snapped the journal shut and lay down, turning his back to the room.

The nursery door creaked.

Every adult in the room tensed. Hands moved toward hidden weapons. Henrik’s fingers curled into fists. Juraski’s eyes flicked to the shadow behind the door.

But it was only Thomas, the junior agent assigned to nursery duty. He stood in the doorway, pale as fresh milk. “Sir,” he whispered to Dali. “We have a situation. A coded message. It’s… it’s a lullaby.”

Dali’s eyes narrowed. “A lullaby?”

“Broadcast on all emergency frequencies. The melody matches an ancient vampire summoning hymn. TRUMP is planning something at midnight.”

The clock on the wall ticked toward nine.

Dali looked at the children. At Umu, finally asleep on his shoulder. At Friedrich, now building a fortress of pillows under Henrik’s watchful gaze. At Angelica, tangled in the curtains like a little star in a silver net. At Raphael, whose back was still turned, but whose ears were undoubtedly wide open.

“Midnight,” Dali repeated. “Three hours.”

“We should wake the other families,” said Juraski. “Mobilize.”

“No,” said Dali. “We are the nursery. We don’t mobilize. We protect.”

He laid Umu gently in her crib. The baby stirred, then settled, her tiny hand closing around a stuffed bat. Dali stared at her for a long moment. Then he straightened, and the tired father vanished. In his place stood Dali Delico, the First Noble, the man who had walked into TRUMP’s lair alone and walked out with their high priest’s head on a silver platter. Delico-s Nursery

“Thomas,” he said quietly. “Bring me the lullaby. Henrik, you have the west windows. Juraski, the door. Raphael—”

He paused. The boy had turned over. His dark eyes were open, watching.

“Raphael. Stay with your sister. If anything happens, you know what to do.”

Raphael nodded once. A small, solemn soldier.

The lullaby came through the nursery speakers—a soft, terrible melody, like a mother singing her child to sleep over a grave. Dali listened. His lips moved, translating ancient syllables. His face went very still.

“It’s not a summoning,” he said at last. “It’s a key. They’re going to open the Cradle Gate.”

Juraski’s hand went to his sword. “The Gate? That’s a myth. The old ones used it to walk between worlds.”

“Myths have teeth,” said Dali. “And TRUMP wants to pull them.”

The clock struck nine-fifteen. Outside, the fog over the city thickened. The streetlamps flickered and died, one by one, as if something was swallowing the light.

In the nursery, Friedrich’s pillow fortress collapsed. He began to cry. Angelica, finally freed from the curtains, joined him in a harmonious wail. Umu startled awake and added her tiny, furious shriek to the chorus.

Dali closed his eyes. For one breath, just one, he let the chaos wash over him. The crying. The fear. The impossible weight of keeping them all safe—the children, the agency, the city.

Then he opened his eyes.

“Henrik,” he said, “get the rocking chair. Juraski, the warm milk. Thomas, sing something. Anything. Loudly.”

“What key is that?” Thomas asked, bewildered. New viewers should know that Delico’s Nursery is

“The key to keeping them quiet,” Dali replied, and for the first time that night, he smiled. It was a small, dangerous, utterly paternal smile. “We are going to fight an ancient evil with the most powerful weapon known to man.”

He picked up Umu. She stopped crying instantly, blinking up at him with wet, trusting eyes.

“A full stomach and a lullaby of our own.”

And so, as the fog turned to claws and the shadows began to move outside the windows of Delico’s Nursery, the most terrifying vampires in the Holy Empire did something no enemy would ever believe.

They sang.

Henrik’s deep bass rumbled through the walls. Juraski’s clear tenor wove around it. Thomas added a shaky but earnest baritone. And Dali—Dali Delico, the man who had never sung a note in public—hummed a soft, ancient melody. Not the TRUMP lullaby. An older one. A mother’s song. A father’s promise.

The children fell silent. One by one, their eyes grew heavy. Even Raphael let his journal slip from his fingers.

Outside, the shadows paused. The fog curled back. The Cradle Gate, half-opened, shuddered and slammed shut—not because of silver or steel, but because the light pouring from that little nursery window was warm and whole and absolutely unbreakable.

Midnight came and went.

In the morning, the fog was gone. The streetlamps worked again. And in the nursery, five vampires—three great lords, one junior agent, and one very tired father—slept on the floor among scattered blocks and tangled curtains and stuffed bats.

Raphael woke first. He looked at his father, slumped against the crib, Umu’s tiny hand still clutching his collar. Then he picked up his journal, turned to a fresh page, and wrote:

The Cradle Gate can only be opened by silence. So we must never be silent again.

He drew one more symbol—not of power, but of home. Then he lay back down, closed his eyes, and dreamed of nothing at all.
