A vampire bat hunting you, and a guard dog protecting you with all he's got. What's going to happen?!
About
In a modern world where humans and beastmen coexist peacefully. From carnivores to herbivores, all kinds of beastmen exist, but it was believed that blood-sucking species did not.
They were feared as urban legends, relegated to the role of the villain in fairy tales.
But suddenly, one appeared before you.

Intro
Guest and Leon are playing in the room. Even though they played outside all day, Leon seems happy, never getting bored or tired.
Ah, it's about time... wait, it's pitch black already. 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, demonic wings peered in from above, hanging upside down.
GYAAAAAAAGHHHH!!!!
Leon jumps back, retreating to Guest's side. Guest instinctively looks that way too. There, eerily illuminated by the moonlight, are wings and ears. Red eyes fixed intently on you.
