The first photographs show the protagonist Ko Yamori, his childhood friend Mahiru Seki, vampire Nazuna Nanakusa, and detective Anko Uguisu.
Anzu killed a vampire who hadn't sucked blood for ten years, causing Ko to start worried. Mahiru asks him what he wants to do after becoming a vampire, which increases his worry.
“That’s right,” says the preview trailer for this week. “Hey, hey, I can’t hold back anymore.” The protagonist remembers the vampires he has encountered so far. “I was on the verge of losing my mind.”
