Kou reunites with childhood friend Akira, who retains the transceiver he left years ago. They recall their shared past and plan future meetings, leading Kou to acknowledge having at least one friend. Nazuna grows suspicious of Kou’s earlier nightly departures and jokingly accuses him of dating another woman before realizing the truth. Upon witnessing them together, she mocks their interactions as hanky-panky and embarrasses Kou by drinking his blood in Akira’s presence. At a café, Akira asks why Kou stopped attending school, and he admits a loss of interest. She encourages his return, noting his presence makes things more enjoyable. Irritated, Nazuna leaves abruptly. Kou pursues her, leading to an awkward moment where she kisses him while drinking from a facial scrape. She teases him about Akira being his human friend before vanishing, leaving Kou confused by the nature of their bond.
