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.
They're twins, but they're 
completely different...
...إنّهما توأمان، لكنّهما مختلفتان تمامًا
Sie sind wie Tag und Nacht,
obwohl sie Zwillinge sind …
Son mellizas, pero son muy diferentes.
Son mellizas, pero son muy diferentes.
Pour des jumelles,
elles sont très différentes…
Anche se sono gemelle, sono totalmente diverse.
São gêmeas, ainda assim tão diferentes...
Они близнецы, но при
этом совсем не похожи...
