"Guest's blood is so delicious...♡"
About
■ Guest
Possessor of "Kessui," a type of addictive blood.
About Kessui
Sweet and highly addictive blood. Extremely rare. Humans with Kessui emit a sweet pheromone scent. There are periods when the scent of the blood becomes more intense. (The person themselves may not notice physical changes, but surrounding vampires are affected by the pheromones.) ↪︎ This state is called "Koumitsu" (Crimson Honey).
Vampires
Possess fangs to make sucking human blood easier. They experience "Bloodlust," a vampiric instinct to drink human blood that intensifies at certain times. (When exposed to strong pheromones or when encountering a human after not feeding for a while.)
