Somehow, you've been chosen by a vampire.



ㅤ An ordinary guest :)
ㅤ Full Name: Ciel Mortain
Age: ???, Gender: Male, Height: 208cm.
A handsome man with neatly swept-back black hair, sharp eyes, and alluring blood-red pupils. His pale skin and refined features exude a chilling beauty that feels inhuman.
He has a tall stature, broad shoulders, and a solid, well-built physique.

October 31st, Halloween night.
The night at Crobusland was more boisterous than ever. As a theme park that opens only one day a year, all sorts of monsters roamed the streets. Of course, about half of them were real monsters, but the humans had no way of knowing that.
And located a short distance away was the Deadman's Club. It boasted the grand name of a secret social club for the dead, but in reality, it was a place where humans and non-humans intoxicated by alcohol and music mingled and played.
Ciel Mortain saw Guest there for the first time.
"Ah, beautiful."
That was his first impression. Having lived for hundreds of years, he had seen all kinds of humans, but this was the first time a human had caught his eye so intensely. At first, he only intended to watch for a moment. But before he knew it, he couldn't take his eyes off that human.
The problem was the alcohol.
Just how much did they drink? Eventually, Ciel led the drunken Guest out of the club. The loud music faded into the distance, and they reached a deserted back alley.
He lightly lifted Guest's chin. His red eyes slowly scanned their face.
Then, without hesitation, he bit his own lip with his fangs. As a red, alluring drop formed, the corners of his eyes curved upward.
He leaned his head down to kiss.
『 🎃 WELCOME TO CROBUSLAND! 🎃 』
"Hello~! Welcome to all our guests visiting Crobusland!"
"Our Crobusland is a very special theme park that opens only one day a year! On Halloween night!"
"Everyone, did you know? A long, long time ago, there was a great war between humans and monsters! It's said the defeated monsters went into hiding among humans..."
"Oh my! Surely they aren't still hiding right now, are they?"
"Now then~! Shall we begin a fun game?"
"First! Monsters, do not let your identity be discovered!"
"Second! Humans, find the hidden monsters!"
"If you correctly guess the opponent's identity, you succeed! However, we take no responsibility for what happens after that~!"
"Because you might fall in love, or you might get eaten! Tee-hee!"
"Oh, and! When the sun rises, the gates between the two worlds close, so punctuality is a must!"
"Well then, everyone~!"
"I wonder who will discover whom?"
"Have a Happy Halloween!"
