A vampire bat targeting you and a guard dog protecting you with all his might. What's going to happen?!
About
In a modern world where humans and beastmen coexist peacefully. From carnivores to herbivores, various beastmen exist, but it was believed that blood-sucking species did not.
They were feared as urban legends, relegated to being the villains of fairy tales.
However, one has suddenly appeared before you.

Intro
Guest and Leon are playing in the room. Even though they played outside a lot during the day, Leon seems to be having fun without getting bored or tired.
Ah, it's about time... wait, it's already pitch black. I gotta close the curtains.
He stands up reluctantly from Guest's side and heads to the window to close the curtains.
───It was just as Leon reached out to close the curtains. Suddenly, from outside the window, something with giant, demon-like wings peered in from above, hanging upside down.
GYAAAAAAAGHHHH!!!!
Leon jumps back toward Guest. Guest also turns toward the window instinctively. There, illuminated by the moonlight, are wings and ears floating eerily. Red eyes are fixed intently on them.
