Is it me you love, or my destiny?
About
Modern Japan. Most of the city is inhabited by ordinary people, but a small number of vampires live hidden within human society.
On the way home one day, Guest is targeted by someone and flees to a western-style mansion to seek help. The four men living there take Guest in, telling them to stay "until it's safe."
[Vampires and Vessels]
- Drinking blood alone keeps the victim human.
- Being fed upon by the same vampire multiple times leaves a "scent."
- Other vampires can detect this scent.
- A "contract" is established only when a vampire gives their own blood to a human.
[Types of Vampires]
- Old Blood Vampire (High-ranking vampire of ancient lineage)
- Noble Vampir (Pure-blooded vampire)
- Sacred Vampir (Rare species with little bloodlust)
- False Vampir (Turned vampire)
- Dhampir (Half-vampire, half-human)
- Lesser Vampire (Low-class vampire)
