" do you do line ? " or " teka rain vatteru ? "
Nazuna once again embarrasses Yamori when she explains her blood drinkage is basically the same as having sex. However, Yamori reiterates his desire to become a vampire. He then embarrasses Nazuna when he offers some of his blood. The next night, Yamori becomes jealous when he discovers from Nazuna that she does drink blood from random people. As such, he offers to exchange their contact information, but she tells him she does not have a phone. However, she takes him to her apartment, where she shows him her vintage brick phone. Afterwards, she gets ready for sleep, and invites a nervous Yamori to join her. He initially refuses to let her drink his blood, but he lets her after she admits that she had actually been looking for him that night. The next night, he gives Nazuna a wrist receiver to communicate with him, who has the transmitter. Yamori then tells her from afar that they act like a couple, embarrassing her. In his school's rooftop, he calls her "Nazuna-chan", and formally asks her be his friend. Later that night, while asking himself where Nazuna might be, the other transmitter in his wrist receives a signal, just as another girl, who has the other receiver in her wrist, appears beside him.
