Tetsuo is invited to the Takanashi household, spending some time talking with Hikari and Himari's father while also witnessing some of the feuding that goes on between the two sisters. The next day, as Himari scolds Hikari for not being able to sort out her own hair, Tetsuo brings up the possibility that. as a vampire, she can't see her own reflection in the mirror. This leads Himari to feel guilty about what she has done up until she realises that the superstition is actually false. Later, Kyōko finds herself in the biology prep room with an allegedly sleeping Tetsuo, unaware that he is actually awake.
