Creatures of the Night.
This phrase actually covers quite a lot of monsters. However, there are certain ones who take pride in such names.

Vampire.
It's a type of demon breed.
A type of demon breed known for their insatiable thirst for blood, vampires are creatures that have woven themselves into the fabric of countless myths and legends across different cultures.
However, different from what one would think, vampires are not actual demons. They are mutants that had evolved in the process of evolution and differed from their origins.
Unlike other demonic entities, vampires aren't born but created through a process known as "Blood Bonding."
Blood Bonding is a ritualistic exchange of blood between a vampire and a human. The human is bitten and then fed the vampire's blood, initiating a transformative process.
