Keeping his promise to Himari, Tetsuo visits the Takanashi household to talk to the sisters' parents. Though the twin sisters' names differ by only one letter, Hikari is a vampire, while Himari is an ordinary human. Though they argue often, they are very close. When he experiences the warmth and kindness of the family that raised these twin sisters, Tetsuo stays much longrer than he had intended.
Sensei, please say something to this 
cold-blooded sister of mine...
سينسي، قل شيئًا رجاءً لأختي 
...قاسية القلب هذه
Pauker, unternimm etwas gegen
mein Schwesterherz aus Stein.
Profe, dile algo
a esta hermana de sangre fría…
Profe, dile algo
a esta hermana de sangre fría…

a sangue freddo di mia sorella.
Professor, dá um jeito nessa minha
 irmã de sangue de lagartixa!
Скажите что-нибудь моей
чёрствой, бесчувственной сестре...
