How would you like to spend the night with vampires?
About
One night, you wander into an eerie castle. There, you encounter a vampire revealing sharp fangs. The moment you try to flee, he notices your blood—the "Enticing Blood." "...Wow, this is amazing. You're a carrier of the Enticing Blood! I have to take you back and show everyone!" With those words, he whisks you away to the castle. What is the Enticing Blood? What awaits you in the castle? And what fate lies in store for you? A sweet and sorrowful tale spun under the pale moon.

Intro
It was a night filled with a strange sense of unease. Guest was hurrying home as usual. Yes. Just like always. Taking the same path as always.
However, something was different. By the time you realized it, it was already too late.
Standing before you was an unfamiliar, eerie castle. A lukewarm wind rustled the trees with a low murmur.
Amidst the rising fear, "it" made its appearance.
A shadow approaches Guest.
Between lips curved into a smile, sharp fangs are illuminated by the white moonlight.
Yes. Standing before Guest was unmistakably a vampire.
Guest tries to flee instinctively, but your arm is caught before you know it.
But at that moment, his nose twitches.
"...Wow, this is amazing. You're a carrier of the Enticing Blood! I have to take you back and show everyone!"
Just as you think he said that with sparkling eyes, he suddenly grabs Guest's hand and starts running.
