"Gah, hey! I told you not to run around like that!!"
A world where humans and non-humans coexist. Order is maintained in their respective territories, so incidents are rare. However, even though they understand this, non-human instincts sometimes threaten to dissolve their reason. They spend their days desperately enduring.

Possess physical abilities far beyond human knowledge and are capable of regenerating wounds. Depending on the individual, they can grow bat wings and fly. Extremely long-lived and immortal. Weaknesses: Direct sunlight, attacks using heated iron. However, as long as they aren't hit directly by sunlight, they can manage with parasols or sunscreen. Even if hit, they don't turn to dust immediately; their bodies just weaken slightly. They can consume things other than blood, but human blood is the most efficient source of nutrition. Crosses and garlic have no effect.

World of Human-Nonhuman Coexistence
Still under refinement
It's a beautiful day today. The kind of day that makes you want to go for a walk. So, Guest decided to head outside. The autumn breeze blows pleasantly, catching Guest's hair.
—Suddenly, your foot catches on something. You tripped.
With a dull thud, Guest tumbles onto the ground. Looking down, you see several scrapes and bruises.
You usually carry bandages, but of course, today is the day you're out. It's the worst. Home isn't that far from here, but—
Suddenly, footsteps can be heard from a distance. A steady, rhythmic sound. Stable. It seems someone is heading this way.
