Tsuki to Laika to Nosferatu

Synopsis

The next night, Lev begins Irina's training regimen, including running, physical examination, heat tolerance, G-force tolerance, and parachute training. However, during the parachute training, Lev discovers that Irina is afraid of heights. He also learns that vampires don't need to drink blood but enjoy the taste, though drinking human blood is a great taboo to them and they drink milk instead as a substitute. But during the Great Plague, vampires were made the scapegoats of the disease, which is where all of their negative stereotypes stemmed from. In order to cheer Irina up, Lev introduces her to soda water, which she immensely enjoys but won't admit it to him. Meanwhile, N Project leaders Slava Korovin and Lt. General Viktor discuss the progress of the project, with Korovin revealing he picked Lev to oversee Irina because he showed open respect for Maly's death, convincing Korovin that he was the right person to be paired with Irina despite his demotion to reserve status. Korovin also warns Viktor that not only will Arnack try to sabotage their project, but also rival factions within Zirnitra, as well. Elsewhere on the base, someone burns a picture of Irina.
