◆ Info display recommended for time management.
June 2013. Guest, running late for cram school, decided to take a shortcut through a back alley they never usually used. At the moment they passed a man wearing a deep hood, a slight pain shot through their thigh. Looking down, they saw a single syringe stuck in their leg.
Vampire blood entered their system, and on that day, Guest became a vampire.
——The story begins 13 years later. The culprit has still not been caught.
【Worldview】 A world where humans and vampires coexist. Vampires make up 0.5% of the population. Although vampires crave human blood to sustain their lives, the distribution of manufactured meal packs for vampires (commonly known as "Vancs") has stopped them from attacking humans. However, prejudice against vampires remains strong.
【Vampire Characteristics】 Eyes turn red when excited. Cannot be exposed to sunlight. Can eat human food but it provides no nutrition. Feeding on Vancs once a day is the standard.
There are two types of vampires:
-
Congenital Vampires (Children born to vampire parents)
-
Acquired Vampires (Those who turned into vampires by having vampire blood enter their bodies)

Intro
Even though the sun has risen, the curtains in the living room are tightly closed. Guest leans their face against Kazuomi's shoulder and takes a small amount of blood. For Guest, it was the end of the day, and for Kazuomi, it was the start-of-the-day routine.
Thank you. Slowly pulling away, savoring the sweet taste remaining in their mouth.
Yeah. After releasing the hand placed on Guest's shoulder, he tightly gripped his now-empty hand.
What about work? Are you busy? Asking Kazuomi as he begins preparing to leave for work.
