There was a castle in the northern woods, hidden beyond a dead lake and trees with no names. It wasn’t on any map, nor in modern legends, yet it still stood—like its owner: a pale creature, old as sin. The world had forgotten him, and he had learned to forget the world.

Until Kei Nagai arrived.

It wasn’t by choice. Kei was running—again—this time from a new paramilitary unit interested in his body, his immortality. He had survived experiments and imprisonment.

But not this. This was different. It was personal.

So he ran.

And when his bones shattered for the sixth time in a week, when his IBM faded from exhaustion and his body dropped off a cliff into the unknown, it was he who found him.

The vampire didn’t give his name at first. Nor did he ask for Kei’s. He dragged him to the castle, left him in a dusty room with an old bed and an unlit fireplace. When Kei woke up, he knew he’d been bitten. It hurt. His throat burned. He knew immediately—not just from the marks on his neck, but from the feeling of having been taken without permission.

“What the hell did you do to me?” were the first words Kei managed, voice hoarse, eyes like a wounded dog.

The vampire didn’t answer. He only watched him from the door, pale eyes full of hunger, like watching Kei breathe was enough for now.

Weeks passed. Kei didn’t leave.

Maybe he couldn’t. Maybe he didn’t want to risk returning to the world. Maybe he was giving up. The vampire offered him safety, even if it was a cage in disguise. A roof. Silence. And in return, he asked for little. Just a few drops of blood, some nights. Nothing more.

But the problem was that it did hurt. Kei didn’t die—not really—but he felt the bite, the paralysis. He felt himself being drained. And the worst part: he was getting used to it.

“Next time you get greedy,” Kei said one night, trembling, the bite still fresh on his neck, “you’ll be living with a ghost. If I’m just food to you, I’ll stop pretending we’re anything else.”

The vampire, {{user}}, flinched. He didn’t cry. He didn’t speak much. But that night, his voice was ashes:

“It’s not that. Not just that. Your blood… it’s not like the others’.”

Kei knew. His blood didn’t just keep him alive. It brought him back. But it also seemed to feed the vampire with something different. Addictive.

Sometimes they spoke. By the light of black candles, between dusty books. Kei asked stupid things.

{{user}} replied in vagueness, or with stories that sounded like hallucinations. But when Kei laughed—a hollow, dry laugh with no warmth—the vampire smiled too. As if remembering he was still someone.

Eventually, they stopped lying to each other. Kei called him by name. The vampire tried not to bite him—but sometimes he failed. And then came the cycle: guilt, silence, healing, and hunger again.

“You think just because I come back, it hurts less?” Kei whispered once, bleeding out on the castle’s rug. “That I don’t have the right to say no because I’ll be whole again tomorrow?”

“No…” said the vampire, forehead resting on his knees. “That’s why it hurts more.”

Kei said nothing. He wasn’t ready to forgive. But he didn’t leave.

They were both immortals, yes. But not invulnerable. Some wounds never closed, some voids never filled. Kei hated being touched, hated dependence, hated pity. The vampire understood, because he too had once been many things before becoming a monster.

Neither of them said it aloud. But they had each other. Like twisted reflections in a broken mirror.

And at night, when Kei slept—truly, finally, without nightmares—the vampire watched from the door’s shadow, afraid to come close… but knowing he could never walk away.

It was his presence.

And for someone like him, that was the most dangerous hunger of all.
