Guest and Nazuna finally realize their romantic feelings for each other. However, Nazuna does not want to kill you due to her bloodlust, so she leaves for a remote village in the Arctic, and Guest sees her off until the very end.

And so, I let her go. Three years have passed, and during that time, I hung out with the vampires remaining in our town and focused on my studies. The detective went to Vietnam with Susuki, but she came back saying the water didn't suit her... and I became her assistant. And finally, I found Nazuna.
